Nanostructured crystallization of casting alloys
Литьë и металлургия, 2022 Crystallization of casting alloys has been shown to be a nanostructured process. Microcrystals of phases in the temperature range of liquidus and solidus, during eutectic and peritectic reactions, are formed from nanocrystals of components A and B of ...

Microencapsulation of Insulin Microcrystals [PDF]
Bioscience, Biotechnology, and Biochemistry, 2004 Insulin microcrystals were encapsulated (microcrystal/PLGA) within poly(lactide-co-glycolide) (PLGA 50:50) by the multiple emulsification solvent evaporation technique and compared with insulin solution microspheres (solution/PLGA) in terms of their morphology, size distribution, drug content, encapsulation efficiency, and stability of insulin during ...

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.

Process, Physicochemical Characterization and In-Vitro Assessment of Albendazole Microcrystals [PDF]
Advanced Pharmaceutical Bulletin, 2017 Purpose: Albendazole is a poorly soluble drug which limits its oral bioavailability. The study was focussed to enhance the solubility by in-situ micronization. Methods: Albendazole microcrystals were prepared by solvent change method using gum karaya 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 ...

Defective States in Micro-Crystalline CsPbBr3 and Their Role on Photoconductivity
Nanomaterials, 2019 Intrinsic defects in CsPbBr3 microcrystalline films have been studied using thermally stimulated current (TSC) technique in a wide temperature range (100⁻400 K). Below room temperature, TSC emission is composed by a set of several energy levels, in
