Summary: This study investigates the gating response of nanochannels to variations in solution pH and ionic strength using selective sidewall functionalization with a polyelectrolyte brush. The conformational and structural changes of the brush layer within the channels are characterized using specular and off-specular neutron reflectometry. The results demonstrate that the brush state collapses under basic pH, representing an open gate, and expands upon decreasing pH and salt concentration, representing a partially closed gate.

Summary: In response to external stimuli, the tunability of liquid crystal polymers and photonic crystals bilayer structures have been examined, revealing that band shifts are proportional to upper-surface transversal strain rather than bending curvature. Incorporating spontaneous bending and contractions in LCP substrates can enhance the tunability of PC films, especially on stiffer substrates.

Summary: This study reports multi-stimuli-responsive crystals of isonicotinamide (INA) that astonishingly respond to all mechanical force, heat, and humidity. The conversion of mechanical properties from two-dimensional (2D) elasticity to elastoplasticity is achieved through phase transitions. Temperature and humidity trigger phase transformations accompanied by crystal elongation, deformation, and displacement, endowing INA crystals with temperature/humidity-reliant dynamic properties. Additionally, the heat/humidity-induced dynamic motions can be controlled by coating silicone grease onto crystal surfaces. This work explores the structure properties of multi-stimuli-responsive crystals of INA integrated with different mechanical properties, which is important for the design of flexible materials with manifold properties.

Summary: This study investigates the use of highly anisotropic 2D ruthenium oxide nanosheets (RONS) as cocatalysts to enhance photocatalytic oxygen evolution rates on WO3 nanoparticles. The results show that WO3 impregnated with RONS exhibits a fivefold increase in photonic efficiency compared to when impregnated with conventional ruthenium oxide nanoparticles. This improvement is attributed to the lower electrochemical water oxidation overpotential and decreased parasitic light absorption properties of RONS.

Summary: This study reports the synthesis of three topologically different MOFs based on the same M6O4(OH)4 clusters (M = Zr or Hf) and methane-tetrakis(p-biphenyl-carboxylate) (MTBC) linkers. The variable coordination geometry of Zr-oxo clusters and the conformational flexibility of the linker contribute to the outstanding diversity of Zr-based MOFs. The structural disorder of the MOFs expands the range of achievable topologies.

Summary: This study investigates bifunctional solar batteries through simulations and experiments, and provides design guidelines for operating a solar battery using 2D carbon nitride potassium poly(heptazine imide) as a photoanode. By proposing an optical design that focuses on light absorption in a charge collection layer within the photoanode, the study highlights the improved efficiency achieved by rear illumination for K-PHI layer thicknesses >200 nm. Enhancement strategies without modifying the photoactive layer are also proposed. Additionally, adapted Ragone plots demonstrate the potential for improved energy and charge output solely through illumination.

Summary: Due to the unique properties of 2D materials and rare-earth elements, the development of 2D rare-earth nanomaterials has become an increasingly popular research trend. This study investigates 2D nanosheets derived from Pr3+-doped KCa2Nb3O10 particles with varying Pr concentrations in order to understand the relationship between chemical composition, atomic structure, and luminescent properties. The results reveal that the nanosheets contain Ca, Nb, O, and a Pr content ranging from 0.9 to 1.8 at%, with the elimination of K after exfoliation. The crystal structure of the nanosheets is monoclinic, and both thin and thick nanosheets exhibit similar chemical composition to the bulk material.

Summary: Multianionic metal hydrides, with diverse physical properties and complex structures, have recently gained attention. In this study, we report the synthesis of Sr6N[BN2](2)H-3, the first compound that combines nitridoborate, nitride, and hydride anions. The crystal structure, determined using X-ray and neutron powder diffraction, reveals a three-dimensional network of nitridoborate units, strontium atoms, and hydride and nitride anions. Electrochemical measurements indicate the presence of hydride ion conductivity.

Summary: The crystalline lithium oxonitridophosphate Li8+xP3O10-xN1+x was synthesized from P3N5 and Li2O in an ampoule. The compound has a triclinic crystal structure with distinctive complex anion species, including non-condensed P(O,N)(4) tetrahedra and P(O,N)(7) double tetrahedra connected by one N atom. The compound also exhibits mixed occupation of O/N positions, allowing for variation of anionic species. To characterize these motifs, complementary analytical methods were used. The compound displays significant disorder in its double tetrahedra structure, as observed in single-crystal X-ray diffraction. Additionally, the compound is a Li+ ion conductor with a total ionic conductivity of 1.2x10(-7) S cm 1 at 25 degrees C, and an activation energy of 0.47(2) eV.

Summary: Solid-state batteries can be developed using thiophosphate electrolytes like beta-Li3PS4. Different solvent-based methods have been used to prepare these solid electrolytes. To recycle end-of-life solid-state batteries based on thiophosphates, dissolution and recrystallization strategies have been considered, particularly for the recovery of beta-Li3PS4. The recrystallization process is studied and found to require polar, slightly protic solvents such as N-methylformamide (NMF). The recrystallized product must have the intermediate phase Li3PS4 center dot 2NMF removed in order to achieve conductivity similar to the original material.

Summary: This study investigates the electrochemical properties of lithium rare earth metal iodides Li3MI6 and reveals the impact of iso- and aliovalent substitutions on their ionic transport properties. The results show that lithium rare earth metal iodides obtained from solid-state synthesis outperform those synthesized through mechanochemical ball-milling in terms of ionic conductivity and activation energy for ion diffusion. However, when mechanochemical ball-milling is combined with post-synthetic calcination, the iodides show similar ionic conductivities as their counterparts obtained from conventional solid-state synthesis.

Phase and amplitude information were obtained, and parts of the magnonic dispersion relation were determined. The numerical solution of an analytic multilayer model verified the experimental results and predicted the effects of changes in saturation magnetization or interlayer coupling.

The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
