Core-shell nanofibers of polyvinylidene fluoride-based nanocomposites as piezoelectric nanogenerators
(
MDPI AG
, 2020 , Article)
Flexible piezoelectric nanogenerators (PENG) are widely applied to harvest sustainable energy from multiple energy sources. The rational and simple design of PENG have great potential in soft electronics. Here we design a ...
The separation of emulsified water/oil mixtures through adsorption on plasma-treated polyethylene powder
(
MDPI AG
, 2021 , Article)
This paper addresses the preparation and characterization of efficient adsorbents for tertiary treatment (oil content below 100 ppm) of oil/water emulsions. Powdered low-density polyethylene (LDPE) was modified by ...
Power conversion techniques using multi-phase transformer: Configurations, applications, issues and recommendations
(
MDPI
, 2022 , Article)
Recently, the superiority of multi-phase systems in comparison to three-phase energy systems has been demonstrated with regards to power generation, transmission, distribution, and utilization in particular. Generally, two ...
The Special Features of Prenatal and Preimplantation Genetic Counseling in Arab Countries.
(
MDPI
, 2022 , Article Review)
Genetic counseling services have only recently been introduced in most Arab countries, and their utilization is increasing. Prenatal genetic counseling is essential, particularly in the Arab context, which is characterized ...
Mesoporous silica filled smart super oleophilic fibers of triblock copolymer nanocomposites for oil absorption applications
(
Springer Nature
, 2020 , Article)
Super oleophilic fibers of styrene-isoprene-styrene (SIS) block copolymer/mesoporous silica (MS) nanocomposites are fabricated by electrospinning, and their oil absorption efficiency is monitored by following two different ...
