Periplasmic bacterial biomineralization of copper sulfide nanoparticles

, 2022
Metal sulfides are a common group of extracellular bacterial biominerals. Only few cases of intracellular biomineralization have been reported in this group, mostly limited to greigite (Fe3S4) in magnetotactic bacteria.

Modelling anaerobic sulfide removal by sulfide shuttling bacteria

Bioresource Technology
Sulfide oxidizing bacteria are used in industrial biodesulfurization processes to convert sulfide to sulfur. These bacteria can spatially separate sulfide removal from terminal electron transfer, thereby acting as sulfide shuttles. The mechanisms underlying sulfide shuttling are not yet clear. In this work, newly obtained sulfide removal data were used

Sulfide Removal From The Sulfide Spring

Tikrit Journal of Engineering Sciences, 2007
In this study ferrous sulfate had been used as an oxidant for removing the sulfide from water samples taken from sulfide spring in Hamam al-alil south of the Mosul city. The study revealed that ferrous sulfate is efficient in removing sulfide in dose not to exceed to 200mg/l with an efficiency of 77%, also adding of Bentonite clay with ferrous sulfate ...

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

Advanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

Estudo da adsorção de hidrogênio e sulfeto na superfície de paládio: aspectos experimentais (eletroquímica) e teóricos (ab initio e Teoria do Funcional da Densidade)

Química Nova, 2001
The adsorption of H and S2- species on Pd (100) has been studied with ab initio, density-functional calculations and electrochemical methods. A cluster of five Pd atoms with a frozen geometry described the surface.

On the Surface Hardening of Zinc Sulfide Windows by Gallium Sulfide

Materials
This study examines the effect of gallium doping on the phase transformation, transmission, and hardness of commercial multispectral-grade ZnS specimens exposed to Ga2S3 vapor. Using secondary ion mass spectrometry, we show that Ga diffusion extends into the subsurface down to several tens of microns.

Bioorthogonal Photoactivation of 2‐Nitrobenzyl Caged Doxorubicin Anticancer Prodrugs on Gold Nanostars

Advanced Materials, EarlyView.
Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.

Quantifying Solar-Powered Removal of Aqueous and Gaseous Sulfide in a Mine Water Passive Treatment System [PDF]

, 2018
Passive treatment systems can improve water quality for mine water discharges. However, some process units, like vertical flow bioreactors (VFBRs), may produce excess sulfide, which can be a source of nuisance odors and toxicity.
