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 ...
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 ...

Synthetic nano hydroxyapatites (HA) have been considered as potential biomaterials for bone tissue engineering applications because of its excellent biological properties. The present work deals with the synthesis of HA ...
Materials and technologies for the tertiary treatment of produced water contaminated by oil impurities through nonfibrous deep-bed media: A review
(
MDPI AG
, 2020 , Article)
This review covers various aspects of the treatment of emulsified oil/water mixtures and is particularly focused on tertiary treatment, which means the reduction of the oil content from 70-100 ppm to below 10 ppm, depending ...
Performance Enhancement of PPMIM Drives by Using Three 3-Phase Four-Leg Inverters
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
In this article, a multilevel inverter (MLI) scheme is proposed for 9-phase pole phase modulated induction motor (PPMIM) drives. The proposed inverter scheme is realized with the help of three 3-phase four-leg inverters. ...
