Prediction of heterogeneous nucleation condensation effect on the surface of respiratory coal dust and test of dust reduction test

Meitan xuebao
Surface wettability of coal dust particles is an important factor restricting the efficiency of wet dust removal. Heterogeneous nucleation condensation on the surface of coal dust particles is a means without any pollution, without considering the ...

Performance of N95 elastomeric respirators in high humidity and high coal dust concentration environment

International Journal of Mining Science and Technology, 2022
High humidity and high dust concentration in deep coal mines may severely challenge the performance of respirators worn by coal miners. This paper aims at quantitatively evaluating the respirators used in deep coal mines and providing scientific guidance

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network

FEBS Letters, EarlyView.
Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

Characterization of explosion propagation of coal dust deposited by gas explosion convolutions in closed pipelines

Meitan xuebao
To explore the propagation characteristics of gas explosion-induced coal dust detonations in enclosed pipelines, a custom-developed experimental system was employed for gas explosions involving accumulated coal dust.

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Dust emission in powder handling: Free falling particle plume characterisation [PDF]

, 2009
Dust generation during solids handling, principally from the free falling of bulk materials and their impact on stockpiles, can be a health threat for operators and a cause of dust explosions.

Experimental and numerical simulation study on forced ventilation and dust removal of coal mine heading surface

International Journal of Coal Science & Technology
In order to study the problems of unreasonable airflow distribution and serious dust pollution in a heading surface, an experimental platform for forced ventilation and dust removal was built based on the similar principles.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...
