Article Abstract
To overcome shortcomings of the traditional freeze-thaw method for PVA hydrogel preparation, we develop a one-step mild method, which induces PVA crystallization to form hydrogels through small molecules containing hydroxyl and carboxyl groups. The obtained hydrogels showed high mechanical properties, untypical plasticity with short gelation time and repeatable sol-gel transformation.

Yttrium-Doped Zinc Oxide (ZnYO) Electron Transport Layers: A Pathway to Enhanced Efficiency in PbS Colloidal Quantum Dot Solar Cells.

Significant progress has been achieved in PbS colloidal quantum dot solar cells (CQDSCs) by concentrating on structural engineering, band-alignment engineering, and enhancing the interfacial functionality of colloidal quantum dots (CQDs). Nonetheless, designing a durable and efficient photovoltaic device still represents a considerable obstacle for scientists in this domain. The present work demonstrates that the photovoltaic performance of PbS CQDSCs can be increased by adding 1-5 wt % yttrium into the zinc oxide (YZO) ETL.

A palladium-catalyzed construction of amino β-lactone derivatives is described herein. This method applies readily available aryl amines and alkenyl carboxylic acids as starting materials, providing the amino β-lactone under mild reaction conditions in one step. The deuterium labeling experiment revealed that the β-H elimination process after aminopalladation was effectively suppressed under the excess amount of I, thus enabling further oxidation and reductive elimination to afford the target amino β-lactones.

Fluorescent carbon dots (CDs) have garnered significant attention for their unique optoelectronic properties and applications, but their practical employment is hampered by the excessive synthesis temperature, tedious post-processing and limited solid-state luminescence efficiency. Herein, we develop a facile molten salt method to achieve the one-step synthesis of full-color CDs with efficient solid-state emission. Comprehensively, kilogram-scale solid-state CDs with a quantum yield of 90% can be readily synthesized via a salt-assisted approach under mild conditions (100-142 °C) within 10 min.

Supported small and dense high-entropy-alloy nanoparticles (HEA-NPs) are promising functional materials for many applications. However, their synthesis remains a grand challenge because the extreme heating typically required to raise the entropic contribution to the formation of a solid solution unavoidably causes the sintering of HEA-NPs. Herein, we present a one-step continuous-flow spray pyrolysis strategy to synthesize multicomponent (from quinary to denary) HEA-NPs with an average size of <2 nanometers and metal loadings of ~30 wt% uniformly dispersed on various carbon substrates, including graphene and carbon black.

Acetone is a crucial chemical and solvent with extensive industrial applications, traditionally synthesized from propane through multi-step processes that demand high temperatures and pressures. Here, we report a selective one-step conversion of propane to acetone using a heterogeneous electro-Fenton process (h-EFP) under mild conditions. In this process, concentrated ·OH radicals are generated in an iron/carbon hybrid cathode via a two-electron oxygen reduction reaction followed by HO conversion.
