text: 'The elastic Leidenfrost effect occurs when a vaporizable soft solid is lowered
onto a hot surface. Evaporative flow couples to elastic deformation, giving spontaneous
bouncing or steady-state floating. The effect embodies an unexplored interplay
between thermodynamics, elasticity, and lubrication: despite being observed, its
basic theoretical description remains a challenge. Here, we provide a theory of
elastic Leidenfrost floating. As weight increases, a rigid solid sits closer to
the hot surface. By contrast, we discover an elasticity-dominated regime where
the heavier the solid, the higher it floats. This geometry-governed behavior is
reminiscent of the dynamics of large liquid Leidenfrost drops. We show that this
elastic regime is characterized by Hertzian behavior of the solid’s underbelly
and derive how the float height scales with materials parameters. Introducing
a dimensionless elastic Leidenfrost number, we capture the crossover between rigid
and Hertzian behavior. Our results provide theoretical underpinning for recent
experiments, and point to the design of novel soft machines.'

text: "Nominally identical materials exchange net electric charge during contact
through a mechanism that is still debated. ‘Mosaic models’, in which surfaces
are presumed to consist of a random patchwork of microscopic donor/acceptor sites,
offer an appealing explanation for this phenomenon. However, recent experiments
have shown that global differences persist even between same-material samples,
which the standard mosaic framework does not account for. Here, we expand the
mosaic framework by incorporating global differences in the densities of donor/acceptor
sites. We develop\r\nan analytical model, backed by numerical simulations, that
smoothly connects the global and deterministic charge transfer of different materials
to the local and stochastic mosaic picture normally associated with identical
materials. Going further, we extend our model to explain the effect of contact
asymmetries during sliding, providing a plausible explanation for reversal of
charging sign that has been observed experimentally."

text: Models for same-material contact electrification in granular media often rely
on a local charge-driving parameter whose spatial variations lead to a stochastic
origin for charge exchange. Measuring the charge transfer from individual granular
spheres after contacts with substrates of the same material, we find instead a
“global” charging behavior, coherent over the sample’s whole surface. Cleaning
and baking samples fully resets charging magnitude and direction, which indicates
the underlying global parameter is not intrinsic to the material, but acquired
from its history. Charging behavior is randomly and irreversibly affected by changes
in relative humidity, hinting at a mechanism where adsorbates, in particular,
water, are fundamental to the charge-transfer process.

text: Experiments have shown that charge distributions of granular materials are
non-Gaussian, with broad tails that indicate many particles with high charge.
This observation has consequences for the behavior of granular materials in many
settings, and may bear relevance to the underlying charge transfer mechanism.
However, there is the unaddressed possibility that broad tails arise due to experimental
uncertainties, as determining the shapes of tails is nontrivial. Here we show
that measurement uncertainties can indeed account for most of the tail broadening
previously observed. The clue that reveals this is that distributions are sensitive
to the electric field at which they are measured; ones measured at low (high)
fields have larger (smaller) tails. Accounting for sources of uncertainty, we
reproduce this broadening in silico. Finally, we use our results to back out the
true charge distribution without broadening, which we find is still non-Guassian,
though with substantially different behavior at the tails and indicating significantly
fewer highly charged particles. These results have implications in many natural
settings where electrostatic interactions, especially among highly charged particles,
strongly affect granular behavior.

text: Kelvin probe force microscopy (KPFM) is a powerful tool for studying contact
electrification (CE) at the nanoscale, but converting KPFM voltage maps to charge
density maps is nontrivial due to long-range forces and complex system geometry.
Here we present a strategy using finite-element method (FEM) simulations to determine
the Green's function of the KPFM probe/insulator/ground system, which allows us
to quantitatively extract surface charge. Testing our approach with synthetic
data, we find that accounting for the atomic force microscope (AFM) tip, cone,
and cantilever is necessary to recover a known input and that existing methods
lead to gross miscalculation or even the incorrect sign of the underlying charge.
Applying it to experimental data, we demonstrate its capacity to extract realistic
surface charge densities and fine details from contact-charged surfaces. Our method
gives a straightforward recipe to convert qualitative KPFM voltage data into quantitative
charge data over a range of experimental conditions, enabling quantitative CE
at the nanoscale.

text: By rigorously accounting for mesoscale spatial correlations in donor/acceptor
surface properties, we develop a scale-spanning model for same-material tribocharging.
We find that mesoscale correlations affect not only the magnitude of charge transfer
but also the fluctuations—suppressing otherwise overwhelming charge-transfer variability
that is not observed experimentally. We furthermore propose a generic theoretical
mechanism by which the mesoscale features might emerge, which is qualitatively
consistent with other proposals in the literature.

text: Origami is rapidly transforming the design of robots1,2, deployable structures3,4,5,6
and metamaterials7,8,9,10,11,12,13,14. However, as foldability requires a large
number of complex compatibility conditions that are difficult to satisfy, the
design of crease patterns is limited to heuristics and computer optimization.
Here we introduce a systematic strategy that enables intuitive and effective design
of complex crease patterns that are guaranteed to fold. First, we exploit symmetries
to construct 140 distinct foldable motifs, and represent these as jigsaw puzzle
pieces. We then show that when these pieces are fitted together they encode foldable
crease patterns. This maps origami design to solving combinatorial problems, which
allows us to systematically create, count and classify a vast number of crease
patterns. We show that all of these crease patterns are pluripotent—capable of
folding into multiple shapes—and solve exactly for the number of possible shapes
for each pattern. Finally, we employ our framework to rationally design a crease
pattern that folds into two independently defined target shapes, and fabricate
such pluripotent origami. Our results provide physicists, mathematicians and engineers
with a powerful new design strategy.

text: "When grape-sized aqueous dimers are irradiated in a microwave oven, an intense
electromagnetic hotspot forms at their point of contact, often igniting a plasma.
Here we show that this irradiation can result in the injection of mechanical energy.
By examining irradiated hydrogel dimers through high-speed imaging, we find that
they repeatedly bounce off of each other while irradiated. We determine that an
average of 1 lJ of mechanical energy is injected into the pair during each collision.
Furthermore, a characteristic high-pitched audio signal is found to accompany
each collision.\r\nWe show that both the audio signal and the energy injection
arise via an interplay between vaporization and elastic deformations in the region
of contact, the so-called ‘elastic Liedenfrost effect’. Our results establish
a novel, non-contact method of injecting mechanical energy into soft matter systems,
suggesting application in fields such as soft robotics."

text: Electrostatic charging of insulating fine particles can be responsible for
numerous phenomena ranging from lightning in volcanic plumes to dust explosions.
However, even basic aspects of how fine particles become charged are still unclear.
Studying particle charging is challenging because it usually involves the complexities
associated with many-particle collisions. To address these issues, we introduce
a method based on acoustic levitation, which makes it possible to initiate sequences
of repeated collisions of a single submillimeter particle with a flat plate, and
to precisely measure the particle charge in situ after each collision. We show
that collisional charge transfer between insulators is dependent on the hydrophobicity
of the contacting surfaces. We use glass, which we modify by attaching nonpolar
molecules to the particle, the plate, or both. We find that hydrophilic surfaces
develop significant positive charges after contacting hydrophobic surfaces. Moreover,
we demonstrate that charging between a hydrophilic and a hydrophobic surface is
suppressed in an acidic environment and enhanced in a basic one. Application of
an electric field during each collision is found to modify the charge transfer,
again depending on surface hydrophobicity. We discuss these results within the
context of contact charging due to ion transfer, and we show that they lend strong
support to OH− ions as the charge carriers.

text: By investigating the in situ chemical and O-isotope compositions of olivine
in lightly sintered dust agglomerates from the early Solar System, we constrain
their origins and the retention of dust in the protoplanetary disk. The grain
sizes of silicates in these agglomeratic olivine (AO) chondrules indicate that
the grain sizes of chondrule precursors in the Renazzo-like carbonaceous (CR)
chondrites ranged from <1 to 80 µm. We infer this grain size range to be equivalent
to the size range for dust in the early Solar System. AO chondrules may contain,
but are not solely composed of, recycled fragments of earlier formed chondrules.
They also contain 16O-rich olivine related to amoeboid olivine aggregates and
represent the best record of chondrule-precursor materials. AO chondrules contain
one or more large grains, sometimes similar to FeO-poor (type I) and/or FeO-rich
(type II) chondrules, while others contain a type II chondrule core. These morphologies
are consistent with particle agglomeration by electrostatic charging of grains
during collision, a process that may explain solid agglomeration in the protoplanetary
disk in the micrometer size regime. The petrographic, isotopic, and chemical compositions
of AO chondrules are consistent with chondrule formation by large-scale shocks,
bow shocks, and current sheets. The petrographic, isotopic, and chemical similarities
between AO chondrules in CR chondrites and chondrule-like objects from comet 81P/Wild
2 indicate that comets contain AO chondrules. We infer that these AO chondrules
likely formed in the inner Solar System and migrated to the comet forming region
at least 3 Ma after the formation of the first Solar System solids. Observations
made in this study imply that the protoplanetary disk retained a dusty disk at
least ∼3.7 Ma after the formation of the first Solar System solids, longer than
half of the dusty accretion disks observed around other stars.

text: Many fields of study, including medical imaging, granular physics, colloidal
physics, and active matter, require the precise identification and tracking of
particle-like objects in images. While many algorithms exist to track particles
in diffuse conditions, these often perform poorly when particles are densely packed
together—as in, for example, solid-like systems of granular materials. Incorrect
particle identification can have significant effects on the calculation of physical
quantities, which makes the development of more precise and faster tracking algorithms
a worthwhile endeavor. In this work, we present a new tracking algorithm to identify
particles in dense systems that is both highly accurate and fast. We demonstrate
the efficacy of our approach by analyzing images of dense, solid-state granular
media, where we achieve an identification error of 5% in the worst evaluated cases.
Going further, we propose a parallelization strategy for our algorithm using a
GPU, which results in a speedup of up to 10× when compared to a sequential CPU
implementation in C and up to 40× when compared to the reference MATLAB library
widely used for particle tracking. Our results extend the capabilities of state-of-the-art
particle tracking methods by allowing fast, high-fidelity detection in dense media
at high resolutions.

text: The Leidenfrost effect occurs when a liquid or stiff sublimable solid near
a hot surface creates enough vapor beneath it to lift itself up and float. In
contrast, vaporizable soft solids, e.g., hydrogels, have been shown to exhibit
persistent bouncing - the elastic Leidenfrost effect. By carefully lowering hydrogel
spheres towards a hot surface, we discover that they are also capable of floating.
The bounce-to-float transition is controlled by the approach velocity and temperature,
analogously to the "dynamic Leidenfrost effect." For the floating regime,
we measure power-law scalings for the gap geometry, which we explain with a model
that couples the vaporization rate to the spherical shape. Our results reveal
that hydrogels are a promising pathway for controlling floating Leidenfrost objects
through shape.

text: The Leidenfrost effect occurs when an object near a hot surface vaporizes
rapidly enough to lift itself up and hover. Although well understood for liquids
and stiff sublimable solids, nothing is known about the effect with materials
whose stiffness lies between these extremes. Here we introduce a new phenomenon
that occurs with vaporizable soft solids - the elastic Leidenfrost effect. By
dropping hydrogel spheres onto hot surfaces we find that, rather than hovering,
they energetically bounce several times their diameter for minutes at a time.
With high-speed video during a single impact, we uncover high-frequency microscopic
gap dynamics at the sphere/substrate interface. We show how these otherwise-hidden
agitations constitute work cycles that harvest mechanical energy from the vapour
and sustain the bouncing. Our findings suggest a new strategy for injecting mechanical
energy into a widely used class of soft materials, with potential relevance to
fields such as active matter, soft robotics and microfluidics.

text: Four rigid panels connected by hinges that meet at a point form a four-vertex,
the fundamental building block of origami metamaterials. Most materials designed
so far are based on the same four-vertex geometry, and little is known regarding
how different geometries affect folding behavior. Here we systematically categorize
and analyze the geometries and resulting folding motions of Euclidean four-vertices.
Comparing the relative sizes of sector angles, we identify three types of generic
vertices and two accompanying subtypes. We determine which folds can fully close
and the possible mountain-valley assignments. Next, we consider what occurs when
sector angles or sums thereof are set equal, which results in 16 special vertex
types. One of these, flat-foldable vertices, has been studied extensively, but
we show that a wide variety of qualitatively different folding motions exist for
the other 15 special and 3 generic types. Our work establishes a straightforward
set of rules for understanding the folding motion of both generic and special
four-vertices and serves as a roadmap for designing origami metamaterials.

text: Clustering of fine particles is of crucial importance in settings ranging
from the early stages of planet formation to the coagulation of industrial powders
and airborne pollutants. Models of such clustering typically focus on inelastic
deformation and cohesion. However, even in charge-neutral particle systems comprising
grains of the same dielectric material, tribocharging can generate large amounts
of net positive or negative charge on individual particles, resulting in long-range
electrostatic forces. The effects of such forces on cluster formation are not
well understood and have so far not been studied in situ. Here we report the first
observations of individual collide-and-capture events between charged submillimetre
particles, including Kepler-like orbits. Charged particles can become trapped
in their mutual electrostatic energy well and aggregate via multiple bounces.
This enables the initiation of clustering at relative velocities much larger than
the upper limit for sticking after a head-on collision, a long-standing issue
known from pre-planetary dust aggregation. Moreover, Coulomb interactions together
with dielectric polarization are found to stabilize characteristic molecule-like
configurations, providing new insights for the modelling of clustering dynamics
in a wide range of microscopic dielectric systems, such as charged polarizable
ions, biomolecules and colloids.

text: We show that the simplest building blocks of origami-based materials - rigid,
degree-four vertices - are generically multistable. The existence of two distinct
branches of folding motion emerging from the flat state suggests at least bistability,
but we show how nonlinearities in the folding motions allow generic vertex geometries
to have as many as five stable states. In special geometries with collinear folds
and symmetry, more branches emerge leading to as many as six stable states. Tuning
the fold energy parameters, we show how monostability is also possible. Finally,
we show how to program the stability features of a single vertex into a periodic
fold tessellation. The resulting metasheets provide a previously unanticipated
functionality - tunable and switchable shape and size via multistability.

text: While the penetration of objects into granular media is well-studied, there
is little understanding of how objects settle in gravities, geff, different from
that of Earth - a scenario potentially relevant to the geomorphology of planets
and asteroids and also to their exploration using man-made devices. By conducting
experiments in an accelerating frame, we explore geff ranging from 0.4 g to 1.2
g. Surprisingly, we find that the rest depth is independent of geff and also that
the time required for the object to come to rest scales like geff-1/2. With discrete
element modeling simulations, we reproduce the experimental results and extend
the range of geff to objects as small as asteroids and as large as Jupiter. Our
results shed light on the initial stage of sedimentation into dry granular media
across a range of celestial bodies and also have implications for the design of
man-made, extraterrestrial vehicles and structures. Key Points The settling depth
in granular media is independent of gravity The settling time scales like g-1/2
Layering driven by granular sedimentation should be similar.
