text: Cesium lead halide (CsPbX3, X = Cl, Br, I) nanocrystals (NCs) offer exceptional
optical properties for several potential applications but their implementation
is hindered by a low chemical and structural stability and limited processability.
In the present work, we developed a new method to efficiently coat CsPbX3 NCs,
which resulted in their increased chemical and optical stability as well as processability.
The method is based on the incorporation of poly(maleic anhydride-alt-1-octadecene)
(PMA) into the synthesis of the perovskite NCs. The presence of PMA in the ligand
shell stabilizes the NCs by tightening the ligand binding, limiting in this way
the NC surface interaction with the surrounding media. We further show that these
NCs can be embedded in self-standing silicone/glass plates as down-conversion
filters for the fabrication of monochromatic green and white light emitting diodes
(LEDs) with narrow bandwidths and appealing color characteristics.

text: 'The functional properties of quaternary I2–II–IV–VI4 nanomaterials, with
potential interest in various technological fields, are highly sensitive to compositional
variations, which is a challenging parameter to adjust. Here we demonstrate the
presence of phosphonic acids to aid controlling the reactivity of the II element
monomer to be incorporated in quaternary Cu2ZnSnSe4 nanoparticles and thus to
provide a more reliable way to adjust the final nanoparticle metal ratios. Furthermore,
we demonstrate the composition control in such multivalence nanoparticles to allow
modifying charge carrier concentrations in nanomaterials produced from the assembly
of these building blocks. '

text: The control of the phase distribution in multicomponent nanomaterials is critical
to optimize their catalytic performance. In this direction, while impressive advances
have been achieved in the past decade in the synthesis of multicomponent nanoparticles
and nanocomposites, element rearrangement during catalyst activation has been
frequently overseen. Here, we present a facile galvanic replacement-based procedure
to synthesize Co@Cu nanoparticles with narrow size and composition distributions.
We further characterize their phase arrangement before and after catalytic activation.
When oxidized at 350 °C in air to remove organics, Co@Cu core-shell nanostructures
oxidize to polycrystalline CuO-Co3O4 nanoparticles with randomly distributed CuO
and Co3O4 crystallites. During a posterior reduction treatment in H2 atmosphere,
Cu precipitates in a metallic core and Co migrates to the nanoparticle surface
to form Cu@Co core-shell nanostructures. The catalytic behavior of such Cu@Co
nanoparticles supported on mesoporous silica was further analyzed toward CO2 hydrogenation
in real working conditions.

text: The efficient conversion between thermal and electrical energy by means of
durable, silent and scalable solid-state thermoelectric devices has been a long
standing goal. While nanocrystalline materials have already led to substantially
higher thermoelectric efficiencies, further improvements are expected to arise
from precise chemical engineering of nanoscale building blocks and interfaces.
Here we present a simple and versatile bottom-up strategy based on the assembly
of colloidal nanocrystals to produce consolidated yet nanostructured thermoelectric
materials. In the case study on the PbS-Ag system, Ag nanodomains not only contribute
to block phonon propagation, but also provide electrons to the PbS host semiconductor
and reduce the PbS intergrain energy barriers for charge transport. Thus, PbS-Ag
nanocomposites exhibit reduced thermal conductivities and higher charge carrier
concentrations and mobilities than PbS nanomaterial. Such improvements of the
material transport properties provide thermoelectric figures of merit up to 1.7
at 850 K.

text: Copper-based chalcogenides that comprise abundant, low-cost, and environmental
friendly elements are excellent materials for a number of energy conversion applications,
including photovoltaics, photocatalysis, and thermoelectrics (TE). In such applications,
the use of solution-processed nanocrystals (NCs) to produce thin films or bulk
nanomaterials has associated several potential advantages, such as high material
yield and throughput, and composition control with unmatched spatial resolution
and cost. Here we report on the production of Cu3SbSe4 (CASe) NCs with tuned amounts
of Sn and Bi dopants. After proper ligand removal, as monitored by nuclear magnetic
resonance and infrared spectroscopy, these NCs were used to produce dense CASe
bulk nanomaterials for solid state TE energy conversion. By adjusting the amount
of extrinsic dopants, dimensionless TE figures of merit (ZT) up to 1.26 at 673
K were reached. Such high ZT values are related to an optimized carrier concentration
by Sn doping, a minimized lattice thermal conductivity due to efficient phonon
scattering at point defects and grain boundaries, and to an increase of the Seebeck
coefficient obtained by a modification of the electronic band structure with Bi
doping. Nanomaterials were further employed to fabricate ring-shaped TE generators
to be coupled to hot pipes, which provided 20 mV and 1 mW per TE element when
exposed to a 160 °C temperature gradient. The simple design and good thermal contact
associated with the ring geometry and the potential low cost of the material solution
processing may allow the fabrication of TE generators with short payback times.

text: The design and engineering of earth-abundant catalysts that are both cost-effective
and highly active for water splitting are crucial challenges in a number of energy
conversion and storage technologies. In this direction, herein we report the synthesis
of Fe3O4@NiFexOy core-shell nanoheterostructures and the characterization of their
electrocatalytic performance toward the oxygen evolution reaction (OER). Such
nanoparticles (NPs) were produced by a two-step synthesis procedure involving
the colloidal synthesis of Fe3O4 nanocubes with a defective shell and the posterior
diffusion of nickel cations within this defective shell. Fe3O4@NiFexOy NPs were
subsequently spin-coated over ITO-covered glass and their electrocatalytic activity
toward water oxidation in carbonate electrolyte was characterized. Fe3O4@NiFexOy
catalysts reached current densities above 1 mA/cm2 with a 410 mV overpotential
and Tafel slopes of 48 mV/dec, which is among the best electrocatalytic performances
reported in carbonate electrolyte.

text: 'The optimization of a material functionality requires both the rational design
and precise engineering of its structural and chemical parameters. In this work,
we show how colloidal chemistry is an excellent synthetic choice for the synthesis
of novel ternary nanostructured chalcogenides, containing exclusively noble metals,
with tailored morphology and composition and with potential application in the
energy conversion field. Specifically, the Ag-Au-Se system has been explored from
a synthetic point of view, which leads to a set of Ag2Se-based hybrid and ternary
nanoparticles including the room temperature synthesis of the rare ternary Ag3AuSe2
fischesserite phase. An in-depth structural and chemical characterization of all
nanomaterials has been performed, which proofed especially useful for unravelling
the reaction mechanism behind the formation of the ternary phase in solution.
The work is complemented with the thermal and electric characterization of a ternary
Ag-Au-Se nanocomposite with promising results: we found that the use of the ternary
nanocomposite represents a clear improvement in terms of thermoelectric energy
conversion as compared to a binary Ag-Se nanocomposite analogue. '

text: Monodisperse Cu2ZnSnS4 (CZTS) nanocrystals (NCs), with quasi-spherical shape,
were prepared by a facile, high-yield, scalable, and high-concentration heat-up
procedure. The key parameters to minimize the NC size distribution were efficient
mixing and heat transfer in the reaction mixture through intensive argon bubbling
and improved control of the heating ramp stability. Optimized synthetic conditions
allowed the production of several grams of highly monodisperse CZTS NCs per batch,
with up to 5 wt % concentration in a crude solution and a yield above 90%.

text: Size and shape tunability and low-cost solution processability make colloidal
lead chalcogenide quantum dots (QDs) an emerging class of building blocks for
innovative photovoltaic, thermoelectric and optoelectronic devices. Lead chalcogenide
QDs are known to crystallize in the rock-salt structure, although with very different
atomic order and stoichiometry in the core and surface regions; however, there
exists no convincing prior identification of how extreme downsizing and surface-induced
ligand effects influence structural distortion. Using forefront X-ray scattering
techniques and density functional theory calculations, here we have identified
that, at sizes below 8 nm, PbS and PbSe QDs undergo a lattice distortion with
displacement of the Pb sublattice, driven by ligand-induced tensile strain. The
resulting permanent electric dipoles may have implications on the oriented attachment
of these QDs. Evidence is found for a Pb-deficient core and, in the as-synthesized
QDs, for a rhombic dodecahedral shape with nonpolar {110} facets. On varying the
nature of the surface ligands, differences in lattice strains are found.

we characterized the NC surface chemistry and demonstrate the presence of surfactants
in dynamic exchange, which controls the NC growth mechanism. In addition, these
NCs were electronically doped by introducing small amounts of bismuth. To demonstrate
the technological potential of such processed material, after ligand removal by
means of NaNH2, AgSbSe2 NCs were used as building blocks to produce thermoelectric
(TE) nanomaterials. A preliminary optimization of the doping concentration resulted
in a thermoelectric figure of merit (ZT) of 1.1 at 640 K, which is comparable
to the best ZT values obtained with a Pb- and Te-free material in this middle
temperature range, with the additional advantage of the high versatility and low
cost associated with solution processing technologies.

text: Mn3O4@CoMn2O4 nanoparticles (NPs) were produced at low temperature and ambient
atmosphere using a one-pot two-step synthesis protocol involving the cation exchange
of Mn by Co in preformed Mn3O4 NPs. Selecting the proper cobalt precursor, the
nucleation of CoxOy crystallites at the Mn3O4@CoMn2O4 surface could be simultaneously
promoted to form Mn3O4@CoMn2O4–CoxOy NPs. Such heterostructured NPs were investigated
for oxygen reduction and evolution reactions (ORR, OER) in alkaline solution.
Mn3O4@CoMn2O4–CoxOy NPs with [Co]/[Mn] = 1 showed low overpotentials of 0.31 V
at −3 mA·cm–2 and a small Tafel slope of 52 mV·dec–1 for ORR, and overpotentials
of 0.31 V at 10 mA·cm–2 and a Tafel slope of 81 mV·dec–1 for OER, thus outperforming
commercial Pt-, IrO2-based and previously reported transition metal oxides. This
cation-exchange-based synthesis protocol opens up a new approach to design novel
heterostructured NPs as efficient nonprecious metal bifunctional oxygen catalysts.

text: In the quest for more efficient thermoelectric material able to convert thermal
to electrical energy and vice versa, composites that combine a semiconductor host
having a large Seebeck coefficient with metal nanodomains that provide phonon
scattering and free charge carriers are particularly appealing. Here, we present
our experimental results on the thermal and electrical transport properties of
PbS-metal composites produced by a versatile particle blending procedure, and
where the metal work function allows injecting electrons to the intrinsic PbS
host. We compare the thermoelectric performance of composites with microcrystalline
or nanocrystalline structures. The electrical conductivity of the microcrystalline
host can be increased several orders of magnitude with the metal inclusion, while
relatively high Seebeck coefficient can be simultaneously conserved. On the other
hand, in nanostructured materials, the host crystallites are not able to sustain
a band bending at its interface with the metal, becoming flooded with electrons.
This translates into even higher electrical conductivities than the microcrystalline
material, but at the expense of lower Seebeck coefficient values.

text: The coherent optical manipulation of solids is emerging as a promising way
to engineer novel quantum states of matter. The strong time-periodic potential
of intense laser light can be used to generate hybrid photon-electron states.
Interaction of light with Bloch states leads to Floquet-Bloch states, which are
essential in realizing new photo-induced quantum phases. Similarly, dressing of
free-electron states near the surface of a solid generates Volkov states, which
are used to study nonlinear optics in atoms and semiconductors. The interaction
of these two dynamic states with each other remains an open experimental problem.
Here we use time- and angle-resolved photoemission spectroscopy (Tr-ARPES) to
selectively study the transition between these two states on the surface of the
topological insulator Bi2Se3. We find that the coupling between the two strongly
depends on the electron momentum, providing a route to enhance or inhibit it.
Moreover, by controlling the light polarization we can negate Volkov states to
generate pure Floquet-Bloch states. This work establishes a systematic path for
the coherent manipulation of solids via light-matter interaction.

text: In the underdoped copper-oxides, high-temperature superconductivity condenses
from a nonconventional metallic "pseudogap" phase that exhibits a variety
of non-Fermi liquid properties. Recently, it has become clear that a charge density
wave (CDW) phase exists within the pseudogap regime. This CDW coexists and competes
with superconductivity (SC) below the transition temperature Tc, suggesting that
these two orders are intimately related. Here we show that the condensation of
the superfluid from this unconventional precursor is reflected in deviations from
the predictions of BSC theory regarding the recombination rate of quasiparticles.
We report a detailed investigation of the quasiparticle (QP) recombination lifetime,
τqp, as a function of temperature and magnetic field in underdoped HgBa2CuO4+δ
(Hg-1201) and YBa2Cu3O6+x (YBCO) single crystals by ultrafast time-resolved reflectivity.
We find that τqp (T) exhibits a local maximum in a small temperature window near
Tc that is prominent in underdoped samples with coexisting charge order and vanishes
with application of a small magnetic field. We explain this unusual, non-BCS behavior
by positing that Tc marks a transition from phase-fluctuating SC/CDW composite
order above to a SC/CDW condensate below. Our results suggest that the superfluid
in underdoped cuprates is a condensate of coherently-mixed particle-particle and
particle-hole pairs.

text: Visualizing molecular localization at high resolution contributes to understanding
of their functions and roles in physiological and pathological conditions. Sodium
dodecyl sulfate-digested freeze-fracture replica labeling (SDS-FRL) is a powerful
electron microscopy method to study high-resolution two-dimensional distribution
of transmembrane proteins and their tightly associated proteins on platinum-carbon
replica. During treatment with SDS, unfixed proteins and intracellular organelle
are dissolved and integral membrane proteins captured and stabilized by carbon
and platinum deposition are denatured, retaining most of their antigenicity, and
exposed on exoplasmic and protoplasmic surfaces of lipid monolayers. The exposure
of these antigens on the surface of replica facilitates the accessibility of antibodies
and therefore provides higher labeling efficiency than those obtained with other
immunoelectron microscopy techniques. In this chapter, we describe the protocols
of SDS-FRL adapted for mammalian brain samples and an additional procedure for
fluorescence-guided electron microscopy for replica immunolabeling.

text: Hole spins have gained considerable interest in the past few years due to
their potential for fast electrically controlled qubits. Here, we study holes
confined in Ge hut wires, a so-far unexplored type of nanostructure. Low-temperature
magnetotransport measurements reveal a large anisotropy between the in-plane and
out-of-plane g-factors of up to 18. Numerical simulations verify that this large
anisotropy originates from a confined wave function of heavy-hole character. A
light-hole admixture of less than 1% is estimated for the states of lowest energy,
leading to a surprisingly large reduction of the out-of-plane g-factors compared
with those for pure heavy holes. Given this tiny light-hole contribution, the
spin lifetimes are expected to be very long, even in isotopically nonpurified
samples.

text: ATP production requires the establishment of an electrochemical proton gradient
across the inner mitochondrial membrane. Mitochondrial uncouplers dissipate this
proton gradient and disrupt numerous cellular processes, including vesicular trafficking,
mainly through energy depletion. Here we show that Endosidin9 (ES9), a novel mitochondrial
uncoupler, is a potent inhibitor of clathrin-mediated endocytosis (CME) in different
systems and that ES9 induces inhibition of CME not because of its effect on cellular
ATP, but rather due to its protonophore activity that leads to cytoplasm acidification.
We show that the known tyrosine kinase inhibitor tyrphostinA23, which is routinely
used to block CME, displays similar properties, thus questioning its use as a
specific inhibitor of cargo recognition by the AP-2 adaptor complex via tyrosine
motif-based endocytosis signals. Furthermore, we show that cytoplasm acidification
dramatically affects the dynamics and recruitment of clathrin and associated adaptors,
and leads to reduction of phosphatidylinositol 4,5-biphosphate from the plasma
membrane.

text: 'Gene regulation relies on the specificity of transcription factor (TF)–DNA
interactions. Limited specificity may lead to crosstalk: a regulatory state in
which a gene is either incorrectly activated due to noncognate TF–DNA interactions
or remains erroneously inactive. As each TF can have numerous interactions with
noncognate cis-regulatory elements, crosstalk is inherently a global problem,
yet has previously not been studied as such. We construct a theoretical framework
to analyse the effects of global crosstalk on gene regulation. We find that crosstalk
presents a significant challenge for organisms with low-specificity TFs, such
as metazoans. Crosstalk is not easily mitigated by known regulatory schemes acting
at equilibrium, including variants of cooperativity and combinatorial regulation.
Our results suggest that crosstalk imposes a previously unexplored global constraint
on the functioning and evolution of regulatory networks, which is qualitatively
distinct from the known constraints that act at the level of individual gene regulatory
elements.'

abstract:
- lang: eng
text: Witness encryption (WE) was introduced by Garg et al. [GGSW13]. A WE scheme
is defined for some NP language L and lets a sender encrypt messages relative
to instances x. A ciphertext for x can be decrypted using w witnessing x ∈ L,
but hides the message if x ∈ L. Garg et al. construct WE from multilinear maps
and give another construction [GGH+13b] using indistinguishability obfuscation
(iO) for circuits. Due to the reliance on such heavy tools, WE can cur- rently
hardly be implemented on powerful hardware and will unlikely be realizable on
constrained devices like smart cards any time soon. We construct a WE scheme where
encryption is done by simply computing a Naor-Yung ciphertext (two CPA encryptions
and a NIZK proof). To achieve this, our scheme has a setup phase, which outputs
public parameters containing an obfuscated circuit (only required for decryption),
two encryption keys and a common reference string (used for encryption). This
setup need only be run once, and the parame- ters can be used for arbitrary many
encryptions. Our scheme can also be turned into a functional WE scheme, where
a message is encrypted w.r.t. a statement and a function f, and decryption with
a witness w yields f (m, w). Our construction is inspired by the functional encryption
scheme by Garg et al. and we prove (selective) security assuming iO and statistically
simulation-sound NIZK. We give a construction of the latter in bilinear groups
and combining it with ElGamal encryption, our ciphertexts are of size 1.3 kB at
a 128-bit security level and can be computed on a smart card.
