Bed‐scale quantitative discrimination of hyperpycnites from intrabasinal turbidites—Results from a channelised slope system in the Upper Carboniferous Westward Ho! Formation, United Kingdom

Sedimentology, EarlyView.
ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

The Influence of Sieving on the Dust Explosion Characteristics of a Lignite Coal

Chemical Engineering Transactions, 2019
For the new developments in the area of coal-fired power plants, the flexibility is a major concern. The power plants must be able to operate with a high variety of coal qualities, with different particle size distribution, moisture content and ash ...

Research on dust control mechanism of coal baffle based on CFD-DPM model

Meikuang Anquan
The fully mechanized mining face is among the most critical areas for dust pollution within a mine, in large mining height faces, the elevated coal fall height during the mining process facilitates the dispersion of particulate matter from the coal ...

Analytical model of brittle destruction based on hypothesis of scale similarity

, 2011
The size distribution of dust particles in nuclear fusion devices is close to the power function. A function of this kind can be the result of brittle destruction.

Development and Characterization of Mesoporous Activated Carbon From Cassia fistula Waste

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Waste derived from the Cassia fistula tree, including pods, leaves and bark, was used as a starting material for the synthesis of mesoporous activated carbon (M‐AC) through a single‐step chemical activation process. Characterization of the samples was confirmed by using SEM, XRD, BET, FTIR and EDX analysis.

Sensitivity of Anthropogenic Cloud Droplet Number Change to Preindustrial Emission Inventories and Physics Parameterizations

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Understanding the preindustrial (PI) to present‐day (PD) change in cloud droplet number concentration (ΔNd) is important to constrain the anthropogenic influence on clouds and aid future model projections. Perturbed parameter ensemble simulations of PI and PD conditions in the Energy Exascale Earth System Model (E3SMv3) reveal two locations ...

A Comprehensive Review of Waste‐Derived Materials for Solar Still Performance Enhancement

Advanced Materials Interfaces, Volume 13, Issue 9, 5 May 2026.
Solar desalination reduces energy use and produces freshwater sustainably, but its productivity is limited and cannot meet rising demand. Thus, solar desalination system improvements are sought to boost water productivity. Waste materials are abundantly available and burden the environment, making them low‐cost enhancers for solar desalination systems.
