Electrically conductive electrospun polymeric mats for sensing dispersed vegetable oil impurities inwastewater
(
MDPI AG
, 2019 , Article)
This paper addresses the preparation of electrically conductive electrospun mats on a base of styrene-isoprene-styrene copolymer (SIS) and multiwall carbon nanotubes (CNTs) and their application as active sensing elements ...
Identification of Molecular Fluorophore as a Component of Carbon Dots able to Induce Gelation in a Fluorescent Multivalent-Metal-Ion-Free Alginate Hydrogel
(
Nature Publishing Group
, 2019 , Article)
We introduce a simple approach to fabricate fluorescent multivalent metal ion-free alginate hydrogels, which can be produced using carbon dots accessible from natural sources (citric acid and L-cysteine). Molecular fluorophore ...
Preparation of progressive antibacterial LDPE surface via active biomolecule deposition approach
(
MDPI AG
, 2019 , Article)
The use of polymers in all aspects of daily life is increasing considerably, so there is high demand for polymers with specific properties. Polymers with antibacterial properties are highly needed in the food and medical ...
Recycled polyethylene/paraffin wax/expanded graphite based heat absorbers for thermal energy storage: An artificial aging study
(
MDPI AG
, 2019 , Article)
An artificial aging study of novel heat absorbers based on phase change materials (PCMs) prepared from recycled high-density polyethylene (HDPE), paraffin wax (PW), and expanded graphite (EG) was investigated. The optimal ...
Piezoresistive sensors based on electrospun mats modified by 2D Ti3C2Tx MXene
(
MDPI AG
, 2019 , Article)
The preparation methodology and properties of electroconductive, electrospun mats composed of copolyamide 6,10 and Ti3C2Tx are described in this paper. Mats of several compositions were prepared from a solution of n-propanol. ...
Novel enzyme-free multifunctional bentonite/polypyrrole/silver nanocomposite sensor for hydrogen peroxide detection over a wide pH range
(
MDPI AG
, 2019 , Article)
Precise designs of low-cost and efficient catalysts for the detection of hydrogen peroxide (H2O2) over wide ranges of pH are important in various environmental applications. Herein, a versatile and ecofriendly approach is ...
Anticoagulant activity of cellulose nanocrystals from isora plant fibers assembled on cellulose and sio2 substrates via a layer-by-layer approach
(
MDPI AG
, 2021 , Article)
In this study, we report the isolation of cellulose nanocrystals (CNCs) from Isora plant fibers by sulfuric acid hydrolysis and their assembly on hydrophilic cellulose and silicon-di-oxide (SiO2) surfaces via a layer-by-layer ...
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 ...
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 ...
Facile preparation of N-S co-doped graphene quantum dots (GQDs) from graphite waste for efficient humidity sensing
(
Elsevier B.V.
, 2021 , Article)
In this work, graphene quantum dots (GQDs) were prepared from Graphitic waste. The resulting GQDs were evaluated for the potential application for resistive humidity sensors. The resistive humidity sensors were fabricated ...
