--- _id: '13367' abstract: - lang: eng text: Confining molecules can fundamentally change their chemical and physical properties. Confinement effects are considered instrumental at various stages of the origins of life, and life continues to rely on layers of compartmentalization to maintain an out-of-equilibrium state and efficiently synthesize complex biomolecules under mild conditions. As interest in synthetic confined systems grows, we are realizing that the principles governing reactivity under confinement are the same in abiological systems as they are in nature. In this Review, we categorize the ways in which nanoconfinement effects impact chemical reactivity in synthetic systems. Under nanoconfinement, chemical properties can be modulated to increase reaction rates, enhance selectivity and stabilize reactive species. Confinement effects also lead to changes in physical properties. The fluorescence of light emitters, the colours of dyes and electronic communication between electroactive species can all be tuned under confinement. Within each of these categories, we elucidate design principles and strategies that are widely applicable across a range of confined systems, specifically highlighting examples of different nanocompartments that influence reactivity in similar ways. article_processing_charge: No article_type: original author: - first_name: Angela B. full_name: Grommet, Angela B. last_name: Grommet - first_name: Moran full_name: Feller, Moran last_name: Feller - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn citation: ama: Grommet AB, Feller M, Klajn R.

Utilizing specifically designed grooved quartz capillaries pulled into a sharp pipette, we have fabricated the smallest SQUID-on-tip (SOT) devices with effective diameters down to 39 nm. Integration of a resistive shunt in close proximity to the pipette apex combined with self-aligned deposition of In and Sn, has resulted in SOTs with a flux noise of 42 nΦ0 Hz−1/2, yielding a record low spin noise of 0.29 μB Hz−1/2. In addition, the new SOTs function at sub-Kelvin temperatures and in high magnetic fields of over 2.5 T. Integrating the SOTs into a scanning probe microscope allowed us to image the stray field of a single Fe3O4 nanocube at 300 mK. Our results show that the easy magnetization axis direction undergoes a transition from the 〈111〉 direction at room temperature to an in-plane orientation, which could be attributed to the Verwey phase transition in Fe3O4. article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Y. full_name: Anahory, Y. last_name: Anahory - first_name: H.

Here, we demonstrate that a similar concept can be extended to the optics realm, particularly to propagating phonon polaritons–hybrid light-matter interactions. To do this, we fabricate stacks composed of two twisted slabs of a vdW crystal (α-MoO3) supporting anisotropic phonon polaritons (PhPs), and image the propagation of the latter when launched by localized sources. Our images reveal that, under a critical angle, the PhPs isofrequency curve undergoes a topological transition, in which the propagation of PhPs is strongly guided (canalization regime) along predetermined directions without geometric spreading. These results demonstrate a new degree of freedom (twist angle) for controlling the propagation of polaritons at the nanoscale with potential for nanoimaging, (bio)-sensing, or heat management. acknowledgement: "J.T.-G. and G.Á.-P. acknowledge support through the Severo Ochoa Program from the\r\nGovernment of the Principality of Asturias (nos.

Here, we report a general methodology allowing for reversible switching of such molecules on the surfaces of solid materials. Our method is based on dispersing photochromic compounds within polysilsesquioxane nanowire networks (PNNs), which can be fabricated as transparent, highly porous, micrometer-thick layers on various substrates. We found that azobenzene switching within the PNNs proceeded unusually fast compared with the same molecules in liquid solvents. Efficient isomerization of another photochromic system, spiropyran, from a colorless to a colored form was used to create reversible images in PNN-coated glass. The coloration reaction could be induced with sunlight and is of interest for developing “smart” windows. article_processing_charge: No article_type: original author: - first_name: Zonglin full_name: Chu, Zonglin last_name: Chu - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn citation: ama: Chu Z, Klajn R.

A micron-size magnetic particle attached to the tip of a silicon cantilever is used to locally apply magnetic flux through the superconducting structure. By scanning the tip over the surface of the device and by utilizing the dynamical coupling between the vortices and the cantilever, a high-resolution spatial map of the different vortex configurations is obtained. Moving the tip to a particular location in the map stabilizes a distinct multivortex configuration. Thus, the scanning of the tip over a particular trajectory in space permits nontrivial operations to be performed, such as braiding of individual vortices within a larger vortex ensemble—a key capability required by many proposals for topological quantum computing. acknowledgement: We are grateful to Nadya Mason, Taylor Hughes, and Alexey Bezryadin for useful discussions.

In contrast to freestanding 2D systems, the details of damage creation in supported 2D materials are not fully understood, whereas the majority of experiments have been carried out for 2D targets deposited on substrates. Here, we suggest a universal and computationally efficient scheme to model the irradiation of supported 2D materials, which combines analytical potential molecular dynamics with Monte Carlo simulations and makes it possible to independently assess the contributions to the damage from backscattered ions and atoms sputtered from the substrate. Using the scheme, we study the defect production in graphene and MoS2 sheets, which are the two most important and wide-spread 2D materials, deposited on a SiO2 substrate. For helium and neon ions with a wide range of initial ion energies including those used in a commercial helium ion microscope (HIM), we demonstrate that depending on the ion energy and mass, the defect production in 2D systems can be dominated by backscattered ions and sputtered substrate atoms rather than by the direct ion impacts and that the amount of damage in 2D materials heavily depends on whether a substrate is present or not. We also study the factors which limit the spatial resolution of the patterning process. Our results, which agree well with the available experimental data, provide not only insights into defect production but also quantitative information, which can be used for the minimization of damage during imaging in HIM or optimization of the patterning process. article_processing_charge: No article_type: original author: - first_name: Silvan full_name: Kretschmer, Silvan last_name: Kretschmer - first_name: Mikhail full_name: Maslov, Mikhail id: 2E65BB0E-F248-11E8-B48F-1D18A9856A87 last_name: Maslov orcid: 0000-0003-4074-2570 - first_name: Sadegh full_name: Ghaderzadeh, Sadegh last_name: Ghaderzadeh - first_name: Mahdi full_name: Ghorbani-Asl, Mahdi last_name: Ghorbani-Asl - first_name: Gregor full_name: Hlawacek, Gregor last_name: Hlawacek - first_name: Arkady V. full_name: Krasheninnikov, Arkady V. last_name: Krasheninnikov citation: ama: 'Kretschmer S, Maslov M, Ghaderzadeh S, Ghorbani-Asl M, Hlawacek G, Krasheninnikov AV.

Yet, the physicochemical properties of detergent micelles and lipid bilayers differ markedly and could alter the structural organization of MPs, albeit without general rules. Dodecylphosphocholine (DPC) is the most widely used detergent for MP structure determination by NMR, but the physiological relevance of several prominent structures has been questioned, though indirectly, by other biophysical techniques, e.g., functional/thermostability assay (TSA) and molecular dynamics (MD) simulations. Here, we resolve unambiguously this controversy by probing the functional relevance of three different mitochondrial carriers (MCs) in DPC at the atomic level, using an exhaustive set of solution-NMR experiments, complemented by functional/TSA and MD data. Our results provide atomic-level insight into the structure, substrate interaction and dynamics of the detergent–membrane protein complexes and demonstrates cogently that, while high-resolution NMR signals can be obtained for MCs in DPC, they systematically correspond to nonfunctional states. article_processing_charge: No article_type: original author: - first_name: Vilius full_name: Kurauskas, Vilius last_name: Kurauskas - first_name: Audrey full_name: Hessel, Audrey last_name: Hessel - first_name: Peixiang full_name: Ma, Peixiang last_name: Ma - first_name: Paola full_name: Lunetti, Paola last_name: Lunetti - first_name: Katharina full_name: Weinhäupl, Katharina last_name: Weinhäupl - first_name: Lionel full_name: Imbert, Lionel last_name: Imbert - first_name: Bernhard full_name: Brutscher, Bernhard last_name: Brutscher - first_name: Martin S. full_name: King, Martin S. last_name: King - first_name: Rémy full_name: Sounier, Rémy last_name: Sounier - first_name: Vincenza full_name: Dolce, Vincenza last_name: Dolce - first_name: Edmund R.

In this study, antiferromagnet-based spintronic functionality is demonstrated by combining unique characteristics of the isospin state in Sr2IrO4. Based on magnetic and transport measurements, large and highly anisotropic magnetoresistance (AMR) is obtained by manipulating the antiferromagnetic isospin domains. First-principles calculations suggest that electrons whose isospin directions are strongly coupled to in-plane net magnetic moment encounter the isospin mismatch when moving across antiferromagnetic domain boundaries, which generates a high resistance state. By rotating a magnetic field that aligns in-plane net moments and removes domain boundaries, the macroscopically-ordered isospins govern dynamic transport through the system, which leads to the extremely angle-sensitive AMR. As with this work that establishes a link between isospins and magnetotransport in strongly spin-orbit-coupled AFM Sr2IrO4, the peculiar AMR effect provides a beneficial foundation for fundamental and applied research on AFM spintronics. article_number: '1805564' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Nara full_name: Lee, Nara last_name: Lee - first_name: Eunjung full_name: Ko, Eunjung last_name: Ko - first_name: Hwan Young full_name: Choi, Hwan Young last_name: Choi - first_name: Yun Jeong full_name: Hong, Yun Jeong last_name: Hong - first_name: Muhammad full_name: Nauman, Muhammad id: 32c21954-2022-11eb-9d5f-af9f93c24e71 last_name: Nauman orcid: 0000-0002-2111-4846 - first_name: Woun full_name: Kang, Woun last_name: Kang - first_name: Hyoung Joon full_name: Choi, Hyoung Joon last_name: Choi - first_name: Young Jai full_name: Choi, Young Jai last_name: Choi - first_name: Younjung full_name: Jo, Younjung last_name: Jo citation: ama: Lee N, Ko E, Choi HY, et al.

Herein, recent progress in developing diverse synthetic dissipative self-assembly systems is discussed. The systems reported thus far can be categorized into three classes, in which: i) the fuel chemically modifies the building blocks, thus triggering their self-assembly, ii) the fuel acts as a template interacting with the building blocks noncovalently, and iii) transient states are induced by the addition of two mutually exclusive stimuli.

The oligomeric species that are formed in the early stages of protein aggregation are of great interest, having been linked with the cellular toxicity associated with these conditions. However, these species are not characterized in any detail experimentally, and their properties are not well understood. Many of these species have been found to have approximately spherical morphology and to be held together by hydrophobic interactions. We present here an analytical statistical mechanical model of globular oligomer formation from simple idealized amphiphilic protein monomers and show that this correlates well with Monte Carlo simulations of oligomer formation. We identify the controlling parameters of the model, which are closely related to simple quantities that may be fitted directly from experiment. We predict that globular oligomers are unlikely to form at equilibrium in many polypeptide systems but instead form transiently in the early stages of amyloid formation. We contrast the globular model of oligomer formation to a well-established model of linear oligomer formation, highlighting how the differing ensemble properties of linear and globular oligomers offer a potential strategy for characterizing oligomers from experimental measurements. acknowledgement: We acknowledge support from the Schiff Foundation (A.J.D.), the Royal Society (A.Š.), the Academy of Medical Sciences and Wellcome Trust (A.Š.), Peterhouse, Cambridge (T.C.T.M.), the Swiss National Science foundation (T.C.T.M.), the Wellcome Trust (T.P.J.K.), the Cambridge Centre for Misfolding Diseases (T.P.J.K.), the BBSRC (T.P.J.K.), the Frances and Augustus Newman foundation (T.P.J.K.).

The measurement of heteronuclear (13C, 15N) relaxation rate constants in the presence of a spin-lock radiofrequency field (R1ρ relaxation) provides access to such motions, and an increasing number of studies involving R1ρ relaxation in proteins have been reported. However, two factors that influence the observed relaxation rate constants have so far been neglected, namely, (1) the role of CSA/dipolar cross-correlated relaxation (CCR) and (2) the impact of fast proton spin flips (i.e., proton spin diffusion and relaxation). We show that CSA/D CCR in R1ρ experiments is measurable and that the CCR rate constant depends on ns–ms motions; it can thus provide insight into dynamics. We find that proton spin diffusion attenuates this CCR due to its decoupling effect on the doublet components. For measurements of dynamics, the use of R1ρ rate constants has practical advantages over the use of CCR rates, and this article reveals factors that have so far been disregarded and which are important for accurate measurements and interpretation. article_processing_charge: No article_type: original author: - first_name: Vilius full_name: Kurauskas, Vilius last_name: Kurauskas - first_name: Emmanuelle full_name: Weber, Emmanuelle last_name: Weber - first_name: Audrey full_name: Hessel, Audrey last_name: Hessel - first_name: Isabel full_name: Ayala, Isabel last_name: Ayala - first_name: Dominique full_name: Marion, Dominique last_name: Marion - first_name: Paul full_name: Schanda, Paul id: 7B541462-FAF6-11E9-A490-E8DFE5697425 last_name: Schanda orcid: 0000-0002-9350-7606 citation: ama: 'Kurauskas V, Weber E, Hessel A, Ayala I, Marion D, Schanda P.

Upon exposure to UV light in nonpolar solvents, these nanoparticles self-assembled to afford spherical aggregates, which disassembled rapidly when the UV stimulus was turned off. The sizes of these aggregates depended on the nanoparticle concentration, and their lifetimes could be controlled by adjusting the surface concentration of nitrospiropyran on the nanoparticles. The conformational flexibility of nitrospiropyran, which was altered by modifying the structure of the background ligand, had a profound impact on the self-assembly process. By coating the nanoparticles with a spiropyran lacking the nitro group, a conceptually different self-assembly system, relying on a reversible proton transfer, was realized. The resulting particles spontaneously (in the dark) assembled into aggregates that could be readily disassembled upon exposure to blue light. article_processing_charge: No article_type: original author: - first_name: Pintu K. full_name: Kundu, Pintu K. last_name: Kundu - first_name: Sanjib full_name: Das, Sanjib last_name: Das - first_name: Johannes full_name: Ahrens, Johannes last_name: Ahrens - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn citation: ama: Kundu PK, Das S, Ahrens J, Klajn R.

Using these mixed SAMs, we show switching of the linear optical and second-harmonic response. The effective switching of these surface optical properties relies on a reasonably large cross section and a high photoisomerization yield as well as a long lifetime of the metastable cis isomer. We quantified the switching process by X-ray absorption spectroscopy. The cross sections for the trans–cis and cis–trans photoisomerization with 365 and 455 nm light, respectively, are 1 order of magnitude smaller than in solution. In vacuum, the 365 nm photostationary state comprises 50–74% of the molecules in the cis form, limited by their rapid thermal isomerization back to the trans state. In contrast, the 455 nm photostationary state contains nearly 100% trans-azobenzene. We determined time constants for the thermal cis–trans isomerization of only a few minutes in vacuum and in a dry nitrogen atmosphere but of more than 1 day in ambient air. Our results suggest that adventitious water adsorbed on the surface of the SAM stabilizes the polar cis configuration of azobenzene under ambient conditions. The back reaction rate constants differing by 2 orders of magnitude underline the huge influence of the environment and, accordingly, its importance when comparing various experiments. article_processing_charge: No article_type: original author: - first_name: Thomas full_name: Moldt, Thomas last_name: Moldt - first_name: Daniel full_name: Przyrembel, Daniel last_name: Przyrembel - first_name: Michael full_name: Schulze, Michael last_name: Schulze - first_name: Wibke full_name: Bronsch, Wibke last_name: Bronsch - first_name: Larissa full_name: Boie, Larissa last_name: Boie - first_name: Daniel full_name: Brete, Daniel last_name: Brete - first_name: Cornelius full_name: Gahl, Cornelius last_name: Gahl - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn - first_name: Petra full_name: Tegeder, Petra last_name: Tegeder - first_name: Martin full_name: Weinelt, Martin last_name: Weinelt citation: ama: Moldt T, Przyrembel D, Schulze M, et al.

Such studies have invariably involved the use of spectral filters or spectrally dispersive optical components that are inherently lossy and technically complex. Here we present a new technique for the spectral selection of near-threshold harmonics and their spatial separation from the driving beams without any optical elements. We discover the existence of a narrow phase-matching gate resulting from the combination of the non-collinear generation geometry in an extended medium, atomic resonances and absorption. Our technique offers a filter contrast of up to 104 for the selected harmonics against the adjacent ones and offers multiple temporally synchronized beamlets in a single unified scheme. We demonstrate the selective generation of 133, 80 or 56 nm femtosecond pulses from a 400-nm driver, which is specific to the target gas. These results open new pathways towards phase-sensitive multi-pulse spectroscopy in the vacuum- and extreme-ultraviolet, and frequency-selective output coupling from enhancement cavities. article_processing_charge: No article_type: original author: - first_name: Rajendran full_name: Rajeev, Rajendran last_name: Rajeev - first_name: Johannes full_name: Hellwagner, Johannes last_name: Hellwagner - first_name: Anne full_name: Schumacher, Anne last_name: Schumacher - first_name: Inga full_name: Jordan, Inga last_name: Jordan - first_name: Martin full_name: Huppert, Martin last_name: Huppert - first_name: Andres full_name: Tehlar, Andres last_name: Tehlar - first_name: Bhargava Ram full_name: Niraghatam, Bhargava Ram last_name: Niraghatam - first_name: Denitsa Rangelova full_name: Baykusheva, Denitsa Rangelova id: 71b4d059-2a03-11ee-914d-dfa3beed6530 last_name: Baykusheva - first_name: 'Nan' full_name: Lin, Nan last_name: Lin - first_name: Aaron full_name: von Conta, Aaron last_name: von Conta - first_name: Hans Jakob full_name: Wörner, Hans Jakob last_name: Wörner citation: ama: 'Rajeev R, Hellwagner J, Schumacher A, et al.

Although such confined spaces can be found in various nanostructured materials, such as zeolites, nanoporous organic frameworks and colloidal nanocrystal assemblies, the slow diffusion of molecules in and out of these materials has greatly hampered studying the effect of confinement on their physicochemical properties. Here, we show that this diffusion limitation can be overcome by reversibly creating and destroying confined environments by means of ultraviolet and visible light irradiation. We use colloidal nanocrystals functionalized with light-responsive ligands that readily self-assemble and trap various molecules from the surrounding bulk solution. Once trapped, these molecules can undergo chemical reactions with increased rates and with stereoselectivities significantly different from those in bulk solution. Illumination with visible light disassembles these nanoflasks, releasing the product in solution and thereby establishes a catalytic cycle. These dynamic nanoflasks can be useful for studying chemical reactivities in confined environments and for synthesizing molecules that are otherwise hard to achieve in bulk solution. article_processing_charge: No article_type: original author: - first_name: Hui full_name: Zhao, Hui last_name: Zhao - first_name: Soumyo full_name: Sen, Soumyo last_name: Sen - first_name: T. full_name: Udayabhaskararao, T. last_name: Udayabhaskararao - first_name: Michał full_name: Sawczyk, Michał last_name: Sawczyk - first_name: Kristina full_name: Kučanda, Kristina last_name: Kučanda - first_name: Debasish full_name: Manna, Debasish last_name: Manna - first_name: Pintu K. full_name: Kundu, Pintu K. last_name: Kundu - first_name: Ji-Woong full_name: Lee, Ji-Woong last_name: Lee - first_name: Petr full_name: Král, Petr last_name: Král - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn citation: ama: Zhao H, Sen S, Udayabhaskararao T, et al.
