The chirality of colloids dispersed in achiral liquid crystals shapes colloidal dynamics and interactions, giving rise to chiral supramolecular assemblies and attractive or repulsive colloidal motions.
As the electronic performance of organic semiconductors and other emergent materials improves, researchers call for attention in extracting charge mobility values from field-effect transistors.
Additive manufacturing has been used to fabricate a common stainless steel, which imparts a unique microstructure to this material, making it stronger and more ductile than that produced with conventional methods.
Defects in mercury telluride quantum dots can be exploited to achieve amplified spontaneous emission under continuous-wave optical pumping at ultralow power levels.
In situ transmission electron microscopy resolves atomic structures and dislocation dynamics of surface segregation, providing insights that open a pathway to new advances in interface engineering.
Mobility is an important charge-transport parameter in organic, inorganic and hybrid semiconductors. We outline some of the common pitfalls of mobility extraction from field-effect transistor (FET) measurements and propose practical recommendations to avoid reporting erroneous mobilities in publications.
Antiviral nanoparticle-formulated mimics of heparan sulfate proteoglycans were developed and shown to permit strong viral association as well as inhibition of a range of viruses on in vitro and in vivo models of infection.
Strategies to incorporate a lithium-cation source in lithium-ion capacitors have so far proved challenging. A sacrificial organic lithium salt is now shown to irreversibly provide lithium cations to a graphite electrode during the initial operando charging step without any negative effects.
Isotopic enrichment in hexagonal boron nitride is shown to enhance the propagation properties of phonon polaritons, achieving a threefold enhancement in their lifetime.
Using a sol–gel process, monoliths of metal–organic frameworks were fabricated. With an enhanced methane volumetric uptake of 259 cm3 (STP) cm−3, and robust mechanical properties, this meets technological targets.
Isotope engineering in hexagonal boron nitride can affect its vibrational, electronic and optical properties due to the isotope substitution, as well as induce a change in the van der Waals interactions.
The Berezinskii–Kosterlitz–Thouless transition is observed in a 2D gas of exciton-polaritons, through measurements of the first-order coherence both in space and time.
Coherent 1D MoS2 channels, which are free of dangling bonds and dislocations, can be fabricated in monolayer WSe2, driven by dislocations at the interface of the two materials.
Proceeding from quantum mechanical predictions, a high shear piezoelectric constant of 178 pm V−1 was measured for the amino acid crystal beta glycine. This originates from the efficient packing of the molecules of the amino acid.
