Recent developments in the application of nanomaterials in agroecosystems
(
MDPI AG
, 2020 , Article)
Nanotechnology implies the scientific research, development, and manufacture, along with processing, of materials and structures on a nano scale. Presently, the contamination of metalloids and metals in the soil has gained ...
Preparation and characterization of alumina HDPE composites
(
MDPI AG
, 2020 , Article)
In this study, effects of two different types of porous alumina nanoparticles have been incorporated into high-density polyethylene (HDPE) to study their impact on the properties of the HDPE composite. The dispersion of ...
Highly sensitive humidity sensor based on cadmium selenide quantum dots-polymer composites: synthesis, characterization, and effect of UV/ozone treatment
(
Springer
, 2023 , Article)
This work describes the rational design of thin film-based cadmium selenide quantum dots (CdSe) mixed with conductive polyvinylidene fluoride (PVDF), inducing PVDF-CdSe composite for potential resistive humidity-sensing ...
Heterogeneous Catalysts for Conversion of Biodiesel-Waste Glycerol into High-Added-Value Chemicals
(
MDPI
, 2022 , Article)
The valuable products produced from glycerol transformation have become a research route that attracted considerable benefits owing to their huge volumes in recent decades (as a result of biodiesel production as a byproduct) ...
Electrically conductive, transparent polymeric nanocomposites modified by 2D Ti3C2Tx (MXene)
(
MDPI AG
, 2019 , Article)
The electrically conductive, transparent, and flexible self-standing thin nanocomposite films based on copolyamide matrix (coPA:Vestamelt X1010) modified with 2D Ti3C2Tx (MXene) nanosheets were prepared by casting and their ...
High Dispersion of Platinum Nanoparticles over Functionalized Zirconia for Effective Transformation of Levulinic Acid to Alkyl Levulinate Biofuel Additives in the Vapor Phase
(
MDPI
, 2022 , Article)
In recent years, functionalized metal oxides have been gaining popularity for biomass conversion to fuels and chemicals due to the global energy crisis. This study reports a novel catalyst based on noble metal immobilization ...
