Surface‐Ligand‐Dependent Excited‐State Dynamics in Aqueous CuInSe2/ZnS Quantum Dot–Chlorophyll Assemblies

Advanced Materials Interfaces, EarlyView.
CuInSe2/ZnS quantum dots are synthesized in water and coupled with chlorophyll to probe ligand‐controlled excited‐state interactions. Broad visible–NIR emission and high PLQY are observed. Time‐resolved measurements reveal shortened chlorophyll lifetimes, indicating dynamic quenching via Förster energy and/or charge transfer, highlighting surface ...

Electrical resistivity and induced polarization in the investigation of acid drainage in decommissioning a mine

REM: International Engineering Journal
The opening and development of mines without previous planning can generate costly environmental liabilities that are difficult to recover. The Osamu Utsumi Mine was responsible for extracting uranium until 1995 in open pit mining operations. The sulfide

The Use of Quicklime in Acid Mine Drainage Treatment

Chemical Engineering Transactions, 2017
In this study, quick lime or calcium oxide (CaO) is used to treat acid mine drainage (AMD). Quick lime was obtained from quarry in Simpang Pulai, Ipoh, Perak. Quick lime is produced by calcination process of limestone at a temperature around of 900 °C to 950 °C. Acid mine drainage (AMD) was collected from a tin tailing pond that located in Perak.

Enhancing Small Molecule Sensing With Aptameric Functionalized Nano Devices

Advanced Materials Technologies, EarlyView.
Unveiling an ultra‐sensitive, non‐invasive neurotransmitter sensor. For the first time, a nanoscale sensor for detecting an important neurotransmitter was demonstrated using micro‐electromechanical systems (MEMS) technology. Our approach utilized field‐effect transistor (FET)‐based readout to enable pico‐molar detection of biomarkers in sweat.
