Drying shrinkage behavior of geopolymer mortar based on kaolinitic coal gangue

open access: yesCase Studies in Construction Materials, 2023
The coal industry generated tons of waste over the years of mineral extraction, and the waste disposal leads to soil and air pollution caused by acid mine drainage and spontaneous combustion.

Selective Electrocatalytic Oxidation of Phenol to Benzoquinone via Water Splitting Using a Nonprecious Metal‐Based Electrocatalyst

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
A green process has been developed utilizing electrochemistry to convert inexpensive, readily available phenol derived from lignin into para‐benzoquinone, a valuable chemical widely used in the manufacturing and chemical industries. For the first time, a novel electrocatalytic oxidation system is achieved with high 96.2% conversion of phenols to para ...

Las "esferas" de los valores [PDF]

open access: yes, 1995
El objetivo de este trabajo radica en mostrar cómo el estudio de los valores debe partir de una clasificación en ámbitos o esferas. La lógica interna de cada una de las esferas es independiente de todas las demás, aunque en los distintos mundos de la ...

Toward Deoxygenation Electrolyze with Compensating Catechol Oxidation

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study presents a sustainable electrochemical method for water deoxygenation using catechol as a sacrificial redox additive. It protects carbon electrodes and drives oxygen reduction efficiently. The approach significantly lowers energy use (0.263 Wh L−1) compared to vacuum degassing, reducing dissolved oxygen from 8.8 to 0.06 mg L−1 using low‐cost,

From Flue Gas to Syngas: Composite Electrode Based on Ionic Liquid and Microporous Polymer for MEA‐Based CO2 Electrolysis

open access: yesAngewandte Chemie, EarlyView.
A composite gas‐diffusion electrode (GDE) with a thin CO2‐selective interlayer beneath the catalyst facilitates direct MEA electrolysis of simulated flue gas (with O2) to CO/syngas, eliminating costly pre‐purification. The interlayer—an intrinsically microporous polymer scaffold infused with CO2‐philic [Emim][BF4]—delivers high CO2/N2 and CO2/O2 ...

Price Premiums for Single‐Name and Compound‐Name Geographical Indications in Swiss Cheese Trade

open access: yesAgribusiness, EarlyView.
ABSTRACT Geographical indications (GIs) have become increasingly important in agri‐food markets, especially in Europe. For Swiss cheese imports and exports, we analyze whether GIs are associated with higher trade prices. We find that price premiums can be obtained for both exports and imports. However, this is only the case for cheeses with single name
