Fluorescence quenching near small metal nanoparticles

, 2012
We develop a microscopic model for fluorescence of a molecule (or semiconductor quantum dot) near a small metal nanoparticle. When a molecule is situated close to metal surface, its fluorescence is quenched due to energy transfer to the metal. We perform

Metal–Metal Bonding

, 2013
This chapter deals with the electronic structure of metal-metal bonds in molecular systems, a diverse topic that now spans almost the entire periodic table. The field is most often associated with strong multiple bonds such as the iconic quadruple bond in [Re2Cl8]2-, and the recently discovered ultra-short Cr-Cr quintuple bonds provide a remarkable ...

Environmental surveillance of the health risk of PM2.5-bound metals and metalloids in Wuxi, China, from 2020 to 2023

Frontiers in Public Health
PM2.5 has been a major public concern due to its association with various diseases; however, its contamination is still not well controlled. From 2020 to 2023, the pollution characteristics of PM2.5-bound metals and metalloids were monitored in Wuxi ...

Anti-Corrosion Inhibition of Mild Steel in 1M Hydrochloric Acid solution by using Tiliacora accuminata leaves Extract

International Journal of Electrochemical Science, 2015
Anticorrosion activity of Tiliacora acuminata leaf extract (TALE) as a corrosion inhibitor in 1M HCl has been investigated using mass loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM), UV-

Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

FEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Iron homeostasis disruption and lipid peroxidation in skeletal muscle during short‐term immobilization

FEBS Open Bio, EarlyView.
14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Using porous metals to enhance heat transfer in phase change materials (PCMs) [PDF]

, 2011
Heat transfer enhancement mechanism of Phase Change Materials (PCMs) by high-porosity metal foams was investigated in this study. The Darcy-Brinkman-Forchheimer modified flow model was employed in the numerical simulations to consider the non-Darcy ...

Combustion and Thermal Behavior of Selected Metallic Fuels Used in Pyrotechnic Compositions

Energies
Metal powders have both a high specific energy and a high energy density, which explains their widespread use in energetic materials (propellants, explosives and pyrotechnics).
