Microcrystals and Microfibers of Cellulose from Acrocomia aculeata (Arecaceae) Characterization

Biology and Life Sciences Forum, 2023
In the context of the so-called lignocellulose bio-refinery, the coconut shell (S) and pulp (P) of Acrocomia aculeata (Arecaceae) are interesting agro-industrial wastes that can be used as feedstock for the production of high value-added products.

Nanostructural mechanisms of physicochemical reactions

Литьë и металлургия, 2021
It is generally accepted that physicochemical reactions are mainly molecular atomic. It was shown that liquid water consists of 12 % molecules and 88 % of ice nanocrystals.

Nanostructural phase transformations in eutectoid reactions of binary alloys

Литьë и металлургия, 2023
It is shown that eutectoid reactions of binary alloys are nanostructural processes. The main phase, which decays during the eutectoid reaction, is formed during the crystallization of a metal melt of eutectoid composition. This process is nanostructured.

Sintering Temperature Induced Evolution of Microstructures and Enhanced Electrochemical Performances: Sol-Gel Derived LiFe(MoO4)2 Microcrystals as a Promising Anode Material for Lithium-Ion Batteries

Frontiers in Chemistry, 2018
A facile sol-gel process was used for synthesis of LiFe(MoO4)2 microcrystals. The effects of sintering temperature on the microstructures and electrochemical performances of the as-synthesized samples were systematically investigated through XRD, SEM and

On the stability of aluminum oxide in carbon steel melts

Литьë и металлургия, 2023
It is shown that hydrogen atoms in carbon steel melts are surface‑active elements for aluminum oxide microcrystals. Adsorbed hydrogen atoms reduce the interfacial surface energy and increase the resistance of small aluminum oxide microcrystals to ...

Detection of Microcrystals for CryoEM

, 2020
Here, we present a strategy to identify microcrystals from initial protein crystallization screen experiments and to optimize diffraction quality of those crystals using negative stain transmission electron microscopy (TEM) as a guiding technique. The use of negative stain TEM allows visualization along the process and thus enables optimization of ...

Enteric Entry of Microcrystals.

Experimental Biology and Medicine, 1965
SummaryMicron- and submicron-sized crystals of tricalcium phosphate, of sand and of barium sulfate ingested by rats entered the intestinal epithelium. They then were distributed and deposited in various organs where tricalcium phosphate and sand incited inflammation and granulomas.
