Abstract Electrocatalysts based on Fe and other transition metals are regarded as most promising candidates for accelerating the oxygen evolution reaction (OER), whereas whether is catalytic active site OER still under debate. Here, unary Fe‐ binary FeNi‐ catalysts, FeOOH FeNi(OH) x , produced by self‐reconstruction. The former a dual‐phased FeOOH, possessing abundant vacancies (V O ) mixed‐valence states, delivering highest performance among all iron oxides‐ hydroxides‐ powder catalysts...
Abstract All‐polymer solar cells (all‐PSCs) have achieved impressive progress in photovoltaic performance and stabilities recently. However, their power conversion efficiencies (PCEs) still trail that of small‐molecular acceptor‐based organic (>19%) mainly because the inferior fill factor (FF). Herein, a combined homo hydrocarbon solvent sequential deposition (SD) strategy is presented to boost FF rigid all‐PSCs 77.7% achieve superior PCE 17.7% with excellent stability, which among...
Nickel–iron oxyhydroxides are among the most active electrocatalysts, but their sluggish kinetic of oxygen evolution reaction (OER) limits energy efficiency toward overall water splitting. Here, we present a “cascade electron transfer” strategy through spurring unidirectional transfer different metal sites in Mn-doped FeNiOOH@FeNiP to boost OER and The Mn doping induces cascade from Ni Fe then via metal-O-metal bridge, thus promoting oxidation centers, which turn help charge by increasing...
Here, we report that the water oxidation activity can be significantly increased by confining ruthenium molecular catalysts, such as RuII(bda)(pic)2, in nanocage of SBA-16. The TOF RuII(bda)(pic)2 confined from 1.2 to 8.7 s−1 simply increasing number molecules one seven each nanocage, which is direct evidence for “cooperative activation” mechanism involved a binuclear reaction pathway reactions. high two times homogeneous due enhanced limited space nanocages. Moreover, preliminary kinetic...
This paper develops a novel volumetric parameterization and spline construction framework, which is an effective modeling tool for converting surface meshes to splines. Our new splines are defined upon parametric domain called generalized polycubes (GPCs). A GPC comprises set of regular cube domains topologically glued together. Compared with conventional (CPCs), the much more powerful flexible has improved numerical accuracy computational efficiency when serving as domain. We design...
Immobilization of the chiral salen-metal complex [MnIII(salen)(H2O)2ClO4] on Keggin-type polyoxometalate (POM) skeletons leads to isolation POM derivatives functionalized with complexes, which represent first examples introducing complexes into systems.

Abstract This study reports a novel hydrogel synthesized using only water and the inorganic salts of FeCl 3 .6H 2 O (NH 4 ) 6 Mo 7 24 .4H O, which offers stable host for various ions (including Li + , Na Mg 2+ Zn Mn or Ca ), affording high ionic conductivity. More interestingly, redox pair Fe /Fe 3+ gel renders considerable pseudo‐capacitance, delivering volumetric energy density (4.8 mWh cm −3 based on one‐piece half‐cell) cycling stability. simple approach is convenient effective—by...
Chirally functionalized hollow nanospheres with different surface properties were successfully synthesized by co-condensation of (2S,1'R,2'R)-N-tert-butyloxycarbonylpyrrolidine-2-carboxylic acid [2'-(4-trimethoxysilylbenzylamide)cyclohexyl] amide 1,2-bis(trimethoxysilyl)ethane or tetramethoxysilane using F127 (EO(106)PO(70)EO(106)) as surfactant in water. The TEM and N(2) sorption characterizations show that the particle size nanosphere is 15-21 nm a core diameter 10-16 nm. These...
Abstract The electron transporting layer (ETL) used in high performance inverted perovskite solar cells (PSCs) is typically composed of C 60 , which requires time‐consuming and costly thermal evaporation deposition, posing a significant challenge for large‐scale production. To address this challenge, herein, we present novel design solution‐processible material (ETM) by grafting non‐fullerene acceptor fragment onto . synthesized BTPC exhibits an exceptional solution processability...
Ein beengter „Arbeitsbereich“ hat seine Vorteile, und zwar im Fall eines nicht-aciden festen Katalysators, der durch Einschluss von [CoIII(Salen)] in ein mesoporöses Kieselgel hergestellt wurde. Durch den kooperativen Effekt innerhalb Nanokäfige erhöhte sich die katalytische Aktivität Selektivität beträchtlich. Ethylenoxid konnte bis zu 96 % Ausbeute Ethylenglycol umgesetzt werden.
Abstract Taking silica as an exemplary material system, we studied water‐assisted densification behaviors of different crystallinities (quartz, glass, and vitreous silica). To avoid the complexity in data interpretation, adopted a simple procedure similar to those used for pressing salt pellets IR: compressing powders mold with pure water under ambient conditions. It is discovered that crystalline compacted through liquid lubrication, while amorphous silica's contradict widely regarded...

Man-made ceramics generally undergo harsh manufacturing conditions (e.g., high-temperature sintering). In contrast, mineral structures with superior mechanical strength teeth) are generated in organisms under mild biocompatible conditions. Herein, we report that ceramic objects can be directly produced and strengthened by drying purely inorganic gels (PIGs), mimicking the biological tactic of fabricating continuous monoliths from hydrated amorphous precursors. The overall process is easy...
