Electric Double Layer Engineering Induces O‐Down Interfacial Water Reorientation for Efficient and Long‐Term Seawater Electrolysis

open access: yesAdvanced Energy Materials, EarlyView.
The additive EDTMPS inhibits hydroxides deposition by chelating with Ca2+/Mg2+. It also disrupts the hydrogen bond network of interfacial water and expands the thickness of electric double layer, promoting more free water to flip into adsorbable O‐down configuration.

FIRST REPORT ON PLATINUM-GROUP MINERALS IN CHROMITITES J%OM NORTHWESTERN NEYRIZ OPHIOLITE, IRAN [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 1993
Electron-probe microanalyses and scanning electron microscopy of chrornitites from some ultramafic members of Neyriz ophiolite indicate that sulifides of platinum- group minerals (PGMs) occur as solid inclusions in chromite grains.

Clay minerals in South Australian Holocene basaltic volcanogenic soils and implications for halloysite genesis and structure [PDF]

open access: yes, 2014
The clay mineralogical composition was determined of 8 soils formed from pyroclastic ejecta (tephra) from adjacent 5000-year old basaltic volcanoes at Mounts Gambier and Schank in South Australia.

Application of SEM and EDS for Phase Characteristics Analysis of Platinoid Mineral in the Danba Area

open access: yesYankuang ceshi, 2013
The study on of occurrence states of PGE resources and the smelting of ore mineral has long been a difficult problem to solve due to low grade copper and nickel sulfide, fine grain and the isomorphism of PGE elements in the Danba area.

PGM in chromitites of Kraka massifs (the Southern Urals): diversity and origin

open access: yesGeoresursy
The paper provides results of study of platinum group minerals (PGMs) from 18 ore occurrences and deposits of the Kraka massifs, most of these located in ultramafic rocks of the upper mantle section (15), and several occurrences in a crust-mantle ...

Regrowth resistance: low-level platinum resistance mediated by rapid recovery from platinum-induced cell-cycle arrest [PDF]

open access: yes, 2009
The H69CIS200 and H69OX400 cell lines are novel models of low-level platinum drug resistance developed from H69 human small cell lung cancer cells with eight 4-day treatments of 200 ng/ml cisplatin or 400 ng/ml oxaliplatin respectively. A recovery period

Plasma–Kinetic Coupling and Redox Mechanisms in the Degradation of Acid Red 51 by Atmospheric Corona Discharge

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates the degradation of the xanthene dye Acid Red 51 (ARE‐51) using atmospheric‐pressure corona discharge plasma, integrating electrical characterization, optical emission spectroscopy (OES), kinetic modeling, and physicochemical analysis to establish a unified plasma–liquid interaction framework. A degradation efficiency of
