Liquid Phase Transmission Electron Microscopy: A Window into the Early Stages of Complex Material Formation

open access: yesAdvanced Functional Materials, EarlyView.
Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

The Equality of Sub-Surface Minerals [PDF]

open access: yes, 2010
Sub-surface minerals are in most cases considered to be the proprietary right of a country should those minerals be found within its borders. PRO169 (Indigenous Peoples’ Rights, International Labour Organization) has recorded instances where the private ...

Exploring agglomeration of respirable silica and other particles in coal mine dust

open access: yesScientific Reports
A better understanding of respirable dust particle characteristics is needed to advance exposure monitoring and prevent health effects. In coal mines and other occupational environments, understanding respirable silica is especially important.

Understanding airflow for enhancing Sepair performance [PDF]

open access: yesMATEC Web of Conferences
In this study, a laboratory-scale negative pressure fluidization air gravity separation unit was employed to conduct air velocity tests. Subsequently, computational fluid dynamics (CFD) modelling was utilized to gain insights into the airflow profile and

Nucleation‐Controlled Reconstruction of CuOx for Selective CO2 Electroreduction

open access: yesAdvanced Functional Materials, EarlyView.
The ratio of oxygen vacancies (Ov) and exposed Cu2O (111)/(200) of CuOx precatalyst is modulated by nucleation control of Cu(OH)2 precursor. Low Ov ratio and high ratio of Cu2O (111)/(200) in slow‐nucleated CuOx reconstructs to high‐coordinated oxide‐derived copper (OD‐Cu) during electrochemical CO2 reduction reaction (CO2RR) and exhibits enhanced ...

Minerals in Afghanistan : the potential for copper [PDF]

open access: yes, 2006
There are around 300 documented copper deposits, occurrences and showings in Afghanistan as shown in Figure 1. A variety of styles of copper mineralisation occur in rocks ranging in age from Proterozoic to Neogene.

Prenucleation Species Dictate Foreign Ion Incorporation in the Biomineral Precursor Amorphous Calcium Carbonate

open access: yesAdvanced Functional Materials, EarlyView.
ACC forms via aggregating prenucleation clusters that gatekeep its chemical composition. Ion identity steers the path: Ba and Sr substitute Ca in clusters, thereby inhibiting nucleation, with a dose‐dependent switch of Sr to induction. Mg partitions into Mg‐rich and Mg‐poor clusters; the latter form ACC, expelling Mg.

Investigating the Maturity of Incident Investigations of the Ghanaian Mining Industry and Its Effect on Safety Performance

open access: yesSafety, 2019
Effective incident investigations have been recognised as a vital means of improving safety. Nevertheless, there has been little attempt to link incident investigations to actual safety performance.
