Abstract:
... It has previously been shown that a walk of 250 m (approximately 175 steps/shoe) in a new environment is sufficient to remove and replace particles present on the contact surfaces of footwear. However, it is unknown how quickly this replacement occurs. This paper describes experiments measuring how quickly (in terms of steps) this loss and replacement of VSP occurs.Three environmental exposure sit ...

Abstract:
... Pore size distribution (PSD) is a fundamental petrophysical parameter for shale formation evaluation. Nuclear magnetic resonance (NMR), performing as a widely acknowledged technique, directly measures transverse relaxation time (T₂), which can be converted into PSD via surface relaxivity (SR). Technically, SR is utilized as a constant value in the entire formation, nevertheless, the laboratory cal ...

Biochars produced from wheat straw at 400 °C (BC400) and 700 °C (BC700) were treated with three typical soil minerals to examine the effects of soil minerals on biochar properties and adsorption capacity for sulfamethoxazole (SMX). Mineral treatment enlarged the surface area and pore size of biochar, and the electron donating capacity (EDC) of the mineral-treated biochars also increased due to the ...

Abstract:
... In the densely populated highlands of Madagascar, growing upland rice offers the opportunity to increase the total rice cropping area and to improve food security. However, rice blast was a major constraint for the first cultivars released in the 1990s and consequently limited the extension of upland rice. However, blast epidemics are much less intense in the region of Betafo, where the compositio ...

Low-dimensional organic–inorganic halide perovskites (OIHPs) have attracted intense interest recently for photovoltaic applications, due to their markedly high chemical stability as compared to the widely studied three-dimensional (3D) counterparts. However, low-dimensional OIHPs usually give much lower device performance than the 3D OIHPs. In particular, for the zero-dimensional (0D) OIHPs, it is ...
