text: We advance high-harmonic spectroscopy to resolve molecular charge migration
in time and space and simultaneously demonstrate extensive control over the process.
A multidimensional approach enables us to reconstruct both quantum amplitudes
and phases with a resolution of better than 100 attoseconds and to separately
reconstruct field-free and laser- driven charge migration. Our techniques make
charge migration in molecules measurable on the attosecond time scale and open
new avenues for laser control of electronic primary processes.

text: All attosecond time-resolved measurements have so far relied on the use of
intense near-infrared laser pulses. In particular, attosecond streaking, laser-induced
electron diffraction and high-harmonic generation all make use of non-perturbative
light–matter interactions. Remarkably, the effect of the strong laser field on
the studied sample has often been neglected in previous studies. Here we use high-harmonic
spectroscopy to measure laser-induced modifications of the electronic structure
of molecules. We study high-harmonic spectra of spatially oriented CH3F and CH3Br
as generic examples of polar polyatomic molecules. We accurately measure intensity
ratios of even and odd-harmonic orders, and of the emission from aligned and unaligned
molecules. We show that these robust observables reveal a substantial modification
of the molecular electronic structure by the external laser field. Our insights
offer new challenges and opportunities for a range of emerging strong-field attosecond
spectroscopies.

text: The large majority of three-dimensional structures of biological macromolecules
have been determined by X-ray diffraction of crystalline samples. High-resolution
structure determination crucially depends on the homogeneity of the protein crystal.
Overall ‘rocking’ motion of molecules in the crystal is expected to influence
diffraction quality, and such motion may therefore affect the process of solving
crystal structures. Yet, so far overall molecular motion has not directly been
observed in protein crystals, and the timescale of such dynamics remains unclear.
Here we use solid-state NMR, X-ray diffraction methods and μs-long molecular dynamics
simulations to directly characterize the rigid-body motion of a protein in different
crystal forms. For ubiquitin crystals investigated in this study we determine
the range of possible correlation times of rocking motion, 0.1–100 μs. The amplitude
of rocking varies from one crystal form to another and is correlated with the
resolution obtainable in X-ray diffraction experiments.

text: "In the present note we announce a proof of a strong form of Arnold diffusion
for smooth convex Hamiltonian systems. Let ${\\mathbb T}^2$ be a 2-dimensional
torus and B2 be the unit ball around the origin in ${\\mathbb R}^2$ . Fix ρ >
0. Our main result says that for a 'generic' time-periodic perturbation of an
integrable system of two degrees of freedom $H_0(p)+\\varepsilon H_1(\\theta,p,t),\\quad
\\ \\theta\\in {\\mathbb T}^2,\\ p\\in B^2,\\ t\\in {\\mathbb T}={\\mathbb R}/{\\mathbb
Z}$ , with a strictly convex H0, there exists a ρ-dense orbit (θε, pε, t)(t) in
${\\mathbb T}^2 \\times B^2 \\times {\\mathbb T}$ , namely, a ρ-neighborhood of
the orbit contains ${\\mathbb T}^2 \\times B^2 \\times {\\mathbb T}$ .\r\n\r\nOur
proof is a combination of geometric and variational methods. The fundamental elements
of the construction are the usage of crumpled normally hyperbolic invariant cylinders
from [9], flower and simple normally hyperbolic invariant manifolds from [36]
as well as their kissing property at a strong double resonance. This allows us
to build a 'connected' net of three-dimensional normally hyperbolic invariant
manifolds. To construct diffusing orbits along this net we employ a version of
the Mather variational method [41] equipped with weak KAM theory [28], proposed
by Bernard in [7]."

text: Nature has long inspired scientists with its seemingly unlimited ability to
harness solar energy and to utilize it to drive various physiological processes.
With the help of man-made molecular photoswitches, we now have the potential to
outperform natural systems in many ways, with the ultimate goal of fabricating
multifunctional materials that operate at different light wavelengths. An important
challenge in developing light-controlled artificial molecular machines lies in
attaining a detailed understanding of the photoisomerization-coupled conformational
changes that occur in macromolecules and molecular assemblies. In this issue of
ACS Nano, Bléger, Rabe, and co-workers use force microscopy to provide interesting
insights into the behavior of individual photoresponsive molecules and to identify
contraction, extension, and crawling events accompanying light-induced isomerization.

text: Nanoporous frameworks are polymeric materials built from rigid molecules,
which give rise to their nanoporous structures with applications in gas sorption
and storage, catalysis and others. Conceptually new applications could emerge,
should these beneficial properties be manipulated by external stimuli in a reversible
manner. One approach to render nanoporous frameworks responsive to external signals
would be to immobilize molecular switches within their nanopores. Although the
majority of molecular switches require conformational freedom to isomerize, and
switching in the solid state is prohibited, the nanopores may provide enough room
for the switches to efficiently isomerize. Here we describe two families of nanoporous
materials incorporating the spiropyran molecular switch. These materials exhibit
a variety of interesting properties, including reversible photochromism and acidochromism
under solvent-free conditions, light-controlled capture and release of metal ions,
as well reversible chromism induced by solvation/desolvation.

text: The cyclopropene radical cation (c-C3H₄⁺) is an important but poorly characterized
three-membered-ring hydrocarbon. We report on a measurement of the high-resolution
photoelectron and photoionization spectra of cyclopropene and several deuterated
isotopomers, from which we have determined the rovibrational energy level structure
of the X⁺ (2)B2 ground electronic state of c-C3H₄⁺ at low energies for the first
time. The synthesis of the partially deuterated isotopomers always resulted in
mixtures of several isotopomers, differing in their number of D atoms and in the
location of these atoms, so that the photoelectron spectra of deuterated samples
are superpositions of the spectra of several isotopomers. The rotationally resolved
spectra indicate a C(2v)-symmetric R0 structure for the ground electronic state
of c-C3H₄⁺. Two vibrational modes of c-C3H₄⁺ are found to have vibrational wave
numbers below 300 cm(-1), which is surprising for such a small cyclic hydrocarbon.
The analysis of the isotopic shifts of the vibrational levels enabled the assignment
of the lowest-frequency mode (fundamental wave number of ≈110 cm(-1) in c-C3H₄⁺)
to the CH2 torsional mode (ν₈⁺, A2 symmetry) and of the second-lowest-frequency
mode (≈210 cm(-1) in c-C3H₄⁺) to a mode combining a CH out-of-plane with a CH2
rocking motion (ν₁₅⁺, B2 symmetry). The potential energy along the CH2 torsional
coordinate is flat near the equilibrium structure and leads to a pronounced anharmonicity.

text: We report the observation of macroscopic field-free orientation, i.e., more
than 73% of CO molecules pointing in the same direction. This is achieved through
an all-optical scheme operating at high particle densities (>10(17) cm(-3)) that
combines one-color (ω) and two-color (ω+2ω) nonresonant femtosecond laser pulses.
We show that the achieved orientation solely relies on the hyperpolarizability
interaction as opposed to an ionization-depletion mechanism, thus, opening a wide
range of applications. The achieved strong orientation enables us to reveal the
molecular-frame anisotropies of the photorecombination amplitudes and phases caused
by a shape resonance. The resonance appears as a local maximum in the even-harmonic
emission around 28 eV. In contrast, the odd-harmonic emission is suppressed in
this spectral region through the combined effects of an asymmetric photorecombination
phase and a subcycle Stark effect, generic for polar molecules, that we experimentally
identify.

text: Light-activated self-propelled colloids are synthesized and their active motion
is studied using optical microscopy. We propose a versatile route using different
photoactive materials, and demonstrate a multiwavelength activation and propulsion.
Thanks to the photoelectrochemical properties of two semiconductor materials (α-Fe2O3
and TiO2), a light with an energy higher than the bandgap triggers the reaction
of decomposition of hydrogen peroxide and produces a chemical cloud around the
particle. It induces a phoretic attraction with neighbouring colloids as well
as an osmotic self-propulsion of the particle on the substrate. We use these mechanisms
to form colloidal cargos as well as self-propelled particles where the light-activated
component is embedded into a dielectric sphere. The particles are self-propelled
along a direction otherwise randomized by thermal fluctuations, and exhibit a
persistent random walk. For sufficient surface density, the particles spontaneously
form ‘living crystals’ which are mobile, break apart and reform. Steering the
particle with an external magnetic field, we show that the formation of the dense
phase results from the collisions heads-on of the particles. This effect is intrinsically
non-equilibrium and a novel principle of organization for systems without detailed
balance. Engineering families of particles self-propelled by different wavelength
demonstrate a good understanding of both the physics and the chemistry behind
the system and points to a general route for designing new families of self-propelled
particles.

text: 'Recent studies aimed at investigating artificial analogs of bacterial colonies
have shown that low-density suspensions of self-propelled particles confined in
two dimensions can assemble into finite aggregates that merge and split, but have
a typical size that remains constant (living clusters). In this Letter, we address
the problem of the formation of living clusters and crystals of active particles
in three dimensions. We study two systems: self-propelled particles interacting
via a generic attractive potential and colloids that can move toward each other
as a result of active agents (e.g., by molecular motors). In both cases, fluidlike
“living” clusters form. We explain this general feature in terms of the balance
between active forces and regression to thermodynamic equilibrium. This balance
can be quantified in terms of a dimensionless number that allows us to collapse
the observed clustering behavior onto a universal curve. We also discuss how active
motion affects the kinetics of crystal formation.'

text: We report numerical simulations of membrane tubulation driven by large colloidal
particles. Using Monte Carlo simulations we study how the process depends on particle
size and binding strength, and present accurate free energy calculations to sort
out how tube formation compares with the competing budding process. We find that
tube formation is a result of the collective behavior of the particles adhering
on the surface, and it occurs for binding strengths that are smaller than those
required for budding. We also find that long linear aggregates of particles forming
on the membrane surface act as nucleation seeds for tubulation by lowering the
free energy barrier associated to the process.

text: Using computer simulations, we show that lipid membranes can mediate linear
aggregation of spherical nanoparticles binding to it for a wide range of biologically
relevant bending rigidities. This result is in net contrast with the isotropic
aggregation of nanoparticles on fluid interfaces or the expected clustering of
isotropic insertions in biological membranes. We present a phase diagram indicating
where linear aggregation is expected and compute explicitly the free-energy barriers
associated with linear and isotropic aggregation. Finally, we provide simple scaling
arguments to explain this phenomenology.

text: 'An extensive computational study of the conformational preferences of three
capped dipeptides: Ac-Xxx-Phe-NH2, Xxx = Gly, Ala, Val is reported. On the basis
of local second-order Møller–Plesset perturbation theory (LMP2) and DFT computations
we were able to identify the experimentally observed conformers as γL–γL(g−) and
β-turn I(g+) in Ac-Gly-Phe-NH2, and Ac-Ala-Phe-NH2, and as the closely related
γL(g+)–γL(g−) and β-turn I(a,g+) in Ac-Val-Phe-NH2. In contrast to the experimental
observation that peptides with bulky side chain have a propensity for β-turns,
we show that in Ac-Val-Phe-NH2 the minimum energy structure corresponds to the
experimentally non detected β-strand.'

text: We use numerical simulations to show how a fully flexible filament binding
to a deformable cylindrical surface may acquire a macroscopic persistence length
and a helical conformation. This is a result of the nontrivial elastic response
to deformations of elastic sheets. We find that the filament’s helical pitch is
completely determined by the mechanical properties of the surface, and can be
easily tuned by varying the surface stretching rigidity. We propose simple scaling
arguments to understand the physical mechanism behind this phenomenon and present
a phase diagram indicating under what conditions one should expect a fully flexible
chain to behave as a helical semiflexible filament. Finally, we discuss the implications
of our results.
