Feb 16, 2022 The HCl gas system previously used to produce cellulose nanocrystals was applied on Scots pine wood, aiming at a controlled deconstruction of its macrostructure while understanding the effect on its microstructure. The HCl gas treatments resulted in a well-preserved cellular structure of the wood. Differences in wood initial moisture content (iMC) …

James L. White, Kyonsuku Min, in Comprehensive Polymer Science and Supplements, 1989 9.3.3.1 Technology. Single-screw extruders were introduced to the plastics and rubber industries in the 1870s. 36 They were presumably used for compounding from the time of their introduction. Single-screw extrusion technology has been reviewed in the monographs of Schenkel 37 and …

Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid.This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point.At the melting point, the ordering of ions or molecules in the solid breaks down to a less …

MoS 2 /NiS 2 and WS 2 /NiS 2 p-p heterojunctions are constructed via a simple solid-state synthesis strategy for boosting the oxygen evolution reaction (OER). Importantly, the difference of energy levels can induce the formation of the well-designed built-in electric field and lead to local charge redistribution at the heterointerface of MoS 2 /NiS 2 and WS 2 /NiS 2, thus expediting …

Problem 1. A hot product flow, leaving the reactor, should be cooled from the initial temperature t 1 н = 95 C to the final temperature t 1 к = 50 C; for this purpose, it is directed to a refrigerator, where water with the initial temperature of t 2 н = 20 C is supplied. Please calculate ∆t ср for the direct flow and counter flow conditions in the refrigerator.
