The Electrochemical Oxidation of Substituted Catechols [PDF]
, 1980 The oxidation of substituted catechols was studied by cyclic voltammetry, chronoamperometry, rotating ring‐disk electrode, and coulometry. The results showed that the quinones that were formed from the oxidation of substituted catechols reacted with the ...

Advanced Materials, EarlyView.This review systematically examines the nanomechanical mechanisms of mussel‐inspired molecular interactions, primarily investigated by direct force measurement techniques such as surface forces apparatus and atomic force microscopy. The macroscopic adhesive and self‐healing performances of mussel‐inspired functional materials, including coacervates ...

Stability of a natural palygorskite after a cycle of adsorption-desorption of an emerging pollutant [PDF]
arXiv, 2019 In this paper, we evaluate the structural stability of a natural Cuban clay (an adsorbent of organic pollutants) after an adsorption-desorption process. The clay under study was palygorskite, and sulfamethoxazole was the emerging contaminant. The materials were characterized by X-ray diffraction, attenuated total reflection infrared spectroscopy and ...

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics
Advanced Materials, EarlyView.Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

A Historical Perspective on the Development of an Ethnic Minority Consciousness in the Spanish-Language Press of the Southwest [PDF]
, 1998 Various scholars have treated ethnic newspapers in the United States as if they all have evolved from an immigrant press.(i) While one may accept their analysis of the functions of the ethnic press, there is a substantial and qualitative difference ...
