Evaluating Bicarbonate Electrolyzer Configurations for Energy‐Efficient Formate Production

Advanced Sustainable Systems, EarlyView.
Reactive carbon capture (RCC) with bicarbonate electrolyzers (BEs) offers an efficient alternative to gas‐fed CO2 electrolyzers by eliminating regeneration and pressurization steps. This study optimizes BE configurations and compares RCC chains to gas‐fed carbon chains for formate production.

2‐line Ferrihydrite Enhance Microbial Synthesis of Plant Biostimulants in Composted Biosolid by Regulating Phyla Pseudomonadota and Actinomycetota

Advanced Science, EarlyView.
This study explores how iron and manganese oxides transform sewage sludge into plant biostimulants during composting. Non‐targeted identification reveals the main species of plant biostimulants. Metagenomic analysis reveals that 2‐line ferrihydrite specifically enriches microbial genes for biosynthesis, boosting plant‐growth promoters.

Scalable, Microwave‐Enabled Synthesis of Ternary WxTi1‐xO2 and Heterostructured TiO2‐WO3‐x Colloidal Nanocrystals: Carrier Dynamics and Photocatalytic Properties

Advanced Science, EarlyView.
Two microwave‐assisted synthetic methods, specifically a one‐pot and a seeded‐growth approach, are developed within a hydroalcoholic solution for the growth of single‐phase ternary WxTi1‐xO2 and heterostructured TiO2‐WO3‐x colloidal nanocrystals. Both types of nanocrystals show significant photocatalytic activity for 4‐methoxybenzyl alcohol oxidation ...

Valores semióticos y valores pictóricos

Tópicos del Seminario, 2016
El punto de partida de este estudio es muy simple; a propósito de la pintura, existen numerosos comentarios tanto por parte de los mejores analistas como por parte de los mismos pintores que, de manera inesperada, si nos ponemos a pensarlo, atañen al valor de la frescura.

Selective Conversion of Polyolefin Waste to Branched Alkanes via Methane‐Free Tandem Hydrocracking–Isomerization

Advanced Science, EarlyView.
Scheme illustrating the selective conversion of plastic waste to isomerized C4‐C12 products using RuSZ1 under different reaction conditions. ABSTRACT In recent years, catalytic hydrocracking has emerged as a promising waste‐to‐feedstock solution for processing plastic waste.

In Situ Construction of Cu1+/Cu0 and Cu2+/Cu0 Pairs of Cu‐Based Catalysts for Electrocatalytic Nitrate Reduction

Advanced Science, EarlyView.
CuO and CuPO (Cu2P2O7 and Cu3(PO4)2) as precursors are in suit construction two distinct copper‐based active sites during the NO3RR reaction: Cu1+/Cu0 (derived from CuO) and Cu2+/Cu0 (derived from CuPO). Cu1+/Cu0 is the key to achieving high activity and high selectivity.

Desigualtats matricials lineals amb valors complexos [PDF]

, 2015
Sovint ens trobem davant de desigualtats matricials lineals (LMIs) on les matrius involucrades prenen valors complexos. Es ben conegut que tota LMI complexa es pot reduir a una LMI real.
