The low-temperature sonochemical synthesis of up-converting β NaYF4:Yb,Er mesocrystals
(Elsevier BV, 2022)
In this paper, we report the mild sonochemical synthesis of hexagonal (β) NaYF4:Yb,Er mesocrystals at low temperature of 40 °C. The nucleation and transformation of crystal structures is investigated in the course of time, ...
Hormone receptor binding, selectivity and cytotoxicity of steroid D-homo lactone loaded chitosan nanoparticles for the treatment of breast and prostate cancer cells
(Elsevier BV, 2022)
Chemically modified steroids have a long history as anti-neoplastic drugs. Incorporation of a lactone moiety in the steroid nucleus, as in previously obtained 3β-acetoxy-17-oxa-17a-homoandrost-5-en-16-one (A) and ...
Antioxidant and cell-friendly Fe2TiO5 nanoparticles for food packaging application
(Elsevier Ltd, 2022)
An emerging technology of active packaging enables prolongation of food shelf life by limiting the oxygen transfer and the reactivity of free radicals, which both destruct food freshness. In this work, Fe2TiO5 nanoparticles ...
In vitro colistin susceptibility of pandrug-resistant Ac. baumannii is restored in the presence of selenium nanoparticles
(John Wiley and Sons Inc, 2022)
Aims: To investigate the synergistic activity of colistin and selenium nanoparticles (SeNPs) against pandrug-resistant (PDR) Ac. baumannii. Methods and Results: Chequerboard and time-kill assays were employed to ex- plore ...
High-Precision Method of Moments Applied to Measurement of Dielectric Parameters at Microwave Frequencies
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
A novel high-precision model of a custom-made coaxial chamber used for broadband measurement of the relative complex permittivity at microwave frequencies is presented. The model is based on a surface integral-equation ...
Functional and Environmental Advantage of Cleaning Ti5B1 Master Alloy
(Springer Science and Business Media LLC, 2022)
One of the greatest environmental goals for the aluminum alloys industry is generating higher quality products by introducing cleaner input materials while maintaining low production costs. A typical dilemma for the master ...
Integer Codes Correcting Burst Asymmetric Errors Within a Byte
(Taylor & Francis Group, 2022)
This paper presents two types of integer codes capable of correcting burst asymmetric errors within a byte. The presented codes are constructed with the help of a computer and are very efficient in terms of redundancy. The ...
Pathway to tailor the phase composition, microstructure and mechanical properties of pulsed laser deposited cobalt-substituted calcium phosphate coatings on titanium
(Surface and Coatings Technology, 2022)
Dense calcium phosphate-based ceramics were fabricated to be used as targets for pulsed laser deposition (PLD). Nanostructured cobalt-substituted hydroxyapatite (Co:HAP) was used as a starting powder. To vary phase composition ...
Optimization of Seating Position and Stimulation Pattern in Functional Electrical Stimulation Cycling: Simulation Study
(Institute of Electrical and Electronics Engineers Inc., 2022)
Two significant challenges facing functional electrical stimulation (FES) cycling are the low power output and early onset of muscle fatigue, mainly due to the non-physiological and superficial recruitment of motor units ...
