Summary: A new class of EC polymer has been developed, showing significantly enhanced performance under lower electric fields compared to state-of-the-art materials. This improvement is achieved by increasing the number of polar entities in the polymer through the conversion of a small number of chlorofluoroethylene groups into covalent double bonds. The polymer displays high-entropy polar phases with low energy barrier for electric-field-induced switching, maintaining performance for over one million cycles at low fields suitable for practical EC cooling applications.

Summary: The study shows that CHCS, after hydration-calcination treatment, exhibits higher catalytic activity for tar reforming and faster reaction rate for CO2 absorption with better H-2 selectivity. Increasing temperature helps reduce tar content, but lowers H-2 content and increases CO2 content. A higher Ca/C ratio leads to higher H-2 content.

Summary: The study demonstrates a straightforward approach to generate ring-shaped nanoparticle assemblies in thin films of supramolecular nanocomposites, simplifying and streamlining nanofabrication processes. Directed self-assembly is used to guide the formation of concentric rings with high-quality orbital angular momentum, introducing interparticle coupling as a new design axis. The detailed analysis confirms the flexibility of the supramolecular system in self-regulating the spatial distribution of components, providing guidelines for developing self-regulating DSA as an alternative to incommensurability-driven methods.

Summary: To address the sluggish oxygen evolution kinetics of bismuth vanadate (BiVO4) photoanodes, a vanadium oxide (VOx) with enriched oxygen vacancies was grown on BiVO4 photoanodes using a photo-assisted electrodeposition process. The optimized BiVO4/VOx photoanode showed a significantly enhanced photocurrent density of 6.29 mA cm(-2) at 1.23 V, which was 385% higher compared to the pristine counterpart. The presence of oxygen vacancies in VOx improved the adsorption of water molecules and promoted charge transfer during the oxygen evolution reaction, resulting in excellent photoelectrochemical (PEC) water splitting performance.

Summary: Inorganic perovskite nanosheets (Cs3Bi2I9, Cs3Sb2I9) are synthesized at the liquid-air interface by drop-casting the precursor solution with the addition of iodine. The thickness and lateral size of the nanosheets can be adjusted through the iodine concentration. The iodine repairs iodine vacancies during perovskite growth, resulting in enhanced optical and optoelectronic properties. The liquid-air interfacial growth of ultrathin perovskites provides flexibility for constructing perovskite-based heterostructures and devices at the atomic scale.

Summary: Due to their low cost and simplified production process, electron-transport layer-free (ETL-free) perovskite solar cells (PSCs) have attracted great attention recently. However, the performance of ETL-free PSCs is still at a disadvantage compared to cells with a conventional n-i-p structure due to the severe recombination of charge carriers at the perovskite/anode interface. In this study, a strategy was reported to fabricate stable ETL-free FAPbI3 PSCs by in situ formation of a low dimensional perovskite layer between the FTO and the perovskite. This interlayer improves energy level alignment between the anode and perovskite, facilitates charge carrier transport and collection, and suppresses charge carrier recombination, leading to ETL-free PSCs with a power conversion efficiency (PCE) exceeding 22% under ambient conditions.

Summary: We present a two-dimensional nonHermitian photonic crystal that enables broad-angle coherent perfect absorption-lasing (CPAL) and super-collimation. This is achieved through a combination of nonsymmorphic glide symmetry, gain-loss modulation, and unit cell optimization, resulting in a parity-time phase transition in the band structure along the Brillouin zone boundary. The dispersionless band structure significantly extends the range of incident angles for CPAL and collimation.
