Self-Crosslinked Ellipsoidal Poly(Tannic Acid) Particles for Bio-Medical Applications
(MDPI AG, 2021)
Self-crosslinking of Tannic acid (TA) was accomplished to obtain poly(tannic acid) (p(TA)) particles in single step, surfactant free media using sodium periodate (NaIO4 ) as an oxidizing agent. Almost monodisperse p(TA) ...
Alpha-Glucosidase Enzyme Immobilized Dextran-Co Metal Nanoparticle Cryogel Composite Systems as Dual Catalyst with Enhanced Stability and Catalytic Activity
(John Wiley and Sons Inc, 2023)
Here, dextran (Dex) cryogels were prepared and used for the immobilization of α-Glu enzyme via two different techniques of entrapment and covalent linking. The entrapment of α-Glu enzyme within Dex cryogels (α-GluE@Dex) ...
A simple gradient centrifugation method for bacteria detection in skim milk
(Elsevier Inc., 2023)
Development of simple methods for bacteria detection is of great importance, especially in the undeveloped countries where there are limited resources for microbial testing. Herein, we present a simple gradient ...
Carbon Tetrafluoride, Oxygen, and Air RF Plasma Modified Low-Density Polyethylene and Polydimethylsiloxane
(Springer, 2023)
Low-density polyethylene (LDPE) and polydimethylsiloxane (silicone or PDMS) were exposed to low-pressure air, oxygen (O2), and carbon tetrafluoride (CF4) plasma to modify their surfaces. Plasma power and irradiation time ...
Removal of Cd(II), Co(II), Cr(III), Ni(II), Pb(II) and Zn(II) ions from wastewater using polyethyleneimine (PEI) cryogels
(Academic Press, 2023)
The removal of the target analytes, Cd(II), Co(II), Cr(III), Ni(II), Pb(II), and Zn(II) from contaminated waters was achieved using super porous polyethyleneimine (PEI) cryogels as adsorbent. The optimum values of the ...
Poly(2-aminoethyl methacrylate) based microgels catalyst system to be used in hydrolysis and methanolysis of NaBH4 for H2 generation
(Elsevier Ltd, 2023)
The poly(2-aminoethyl methacrylate) (p(AEM)) microgels were synthesized by microemulsion polymerization technique and used for in situ metal nanoparticle preparation to render as p(AEM)-M (M: Co or Ni) microgel composites ...
Biocompatible Glycol Chitosan Microgels as Effective Drug Carriers
(MDPI, 2023)
Glycol chitosan (GC) is a chitosan (CH) derivative with improved water solubility with regards to CH which affords significant solubility advantages. In this study, microgels of GC as p(GC) were synthesized by a microemulsion ...
Biofouling and Mitigation Methods: A Review
(AMG Transcend Association, 2023)
Biofouling accumulates living organisms on surfaces in contact with the water and causes significant economic, structural, and microbial problems on ship hulls, piers, oil rigs, power plants, pipework, water treatment ...
Physically and Chemically Crosslinked, Tannic Acid Embedded Linear PEI-Based Hydrogels and Cryogels with Natural Antibacterial and Antioxidant Properties
(MDPI, 2023)
Linear polyethyleneimine (L-PEI) was obtained from the acidic hydrolysis of poly(2-ethyl-2-oxazoline) and employed in the synthesis of physically crosslinked L-PEI hydrogel, PC-L-PEIH, chemically crosslinked L-PEI hydrogel, ...
Force-Based Characterization of the Wetting Properties of LDPE Surfaces Treated with CF4 and H-2 Plasmas
(MDPI, 2023)
Low-density polyethylene (LDPE) films are widely used in packaging, insulation and many other commodity applications due to their excellent mechanical and chemical properties. However, the water-wetting and water-repellant ...
