Estudio de la hidrólisis del trietilborato por espectroscopía infrarroja: evaluación de geles de borosilicato

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2007
Triethylborate (TEB) is a boron alkoxide largely used in the synthesis of sol-gel prepared materials. This method requires the hydrolysis and condensation of the synthesis reagents, usually alkoxides, for obtaining a gel which can be transformed into ...

Defect‐Free Block Copolymer‐Based Distributed Bragg Reflector for Optimized Light Harvesting in BiVO4 Photoanodes

open access: yesAdvanced Functional Materials, EarlyView.
A solution‐processed distributed Bragg reflector (DBR) film, integrated via block copolymer (BCP) self‐assembly, enhances photon recycling in BiVO4 photoanodes for improved photoelectrochemical (PEC) performance. By tuning lamellar structures using lactic acid and cross‐linking density, the DBR film optimally shifts working wavelengths, boosting ...

Fluorinated Interphase Enabled by Lithium Salt‐Driven Electrical Double‐Layer Modulation for Advanced Zinc Metal Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a highly soluble, reduction‐active lithium salt into conventional zinc battery electrolytes, enhancing the solvation structure and electric double layer. These modifications significantly improve the reversibility of the zinc anode and mitigate cathode material dissolution, presenting a novel approach to enhancing the performance ...
