Nanotechnology and Food: Brief Overview of the Current Scenario
The rapidly expanding sector of nanotechnologies has applications in every industrial sector. The production of food of animal origin recognizes several possibilities for technological development through the use of nanomaterials, at animal farming, food processing and product storage levels. Direct use of nanomateria…
Design and fabrication of functional polycaprolactone
Abstract Functional polycaprolactone (PCL) has great potential for applications in biomedical areas. This review summarizes the recent progress in the chemical synthesis of functional PCL. The functional PCL can be synthesized by (a) homopolymerization or copolymerization of functional ε-caprolactone (ε-CL), (b) copol…
Adhering magnetic molecules to surfaces
In this review we aim to present an overview of the work that has been performed on attaching and studying Single-Molecule Magnets (SMMs) on various surfaces, with an emphasis on molecular design for surface interaction and on the magnetic properties before and after adhesion occurs.
Ternary silicone sponge with enhanced mechanical properties for oil–water separation
Sponge-like silicone polymers were obtained from a mixture of silanes with di-, tri- and tetra-functional groups. The optimized material exhibited enhanced mechanical properties and stable adsorption capacities for various organic solvents, as well as an excellent recyclability for oil–water separations.
The effect of molecular composition and crosslinking on adhesion of a bio-inspired adhesive
Catechol-containing polymers with a crosslinked structure were obtained by free radical polymerization. Optimal adhesion properties were obtained at a catechol composition of 5 mol%.
Phase-selective gelators based on closed-chain glucose derivatives: their applications in the removal of dissolved aniline/nitrobenzene, and toxic dyes from contaminated water
Easy-to-implement methods were realized with glucose-based gelators for the efficient removal of aniline/nitrobenzene, and toxic dyes from contaminated water.
Self-assembling dual component nanoparticles with endosomal escape capability
This study reports a novel nanoparticle system with simple and modular one-step assembly, which can respond intelligently to biologically relevant variations in pH. Importantly, these particles also show the ability to induce escape from the endosomal/lysosomal compartments of the cell, which is integral to the design…
Interpreting equilibrium-conductivity and conductivity-relaxation measurements to establish thermodynamic and transport properties for multiple charged defect conducting ceramics
A model-based interpretation of measured equilibrium conductivity and conductivity relaxation is developed to establish thermodynamic, transport, and kinetics parameters for multiple charged defect conducting (MCDC) ceramic materials. The present study focuses on 10% yttrium-doped barium zirconate (BZY10). In principl…

Ultrathin porous nickel–cobalt layered double hydroxide (Ni–Co LDH) hybrid nanosheets on metal nickel sheets shows highly electrochemical performance which synthesizing via a facile hydrothermal method without any adscititious surfactant.
Co 3 O 4 particles grown over nanocrystalline CeO 2 : influence of precipitation agents and calcination temperature on the catalytic activity for methane oxidation
Crystalline cobalt oxides were prepared by a precipitation method using three different precipitation agents, (NH 4 ) 2 CO 3 , Na 2 CO 3 and CO(NH 2 ) 2 .
Influence of Filler from a Renewable Resource and Silane Coupling Agent on the Properties of Epoxidized Natural Rubber Vulcanizates
Rice husk ash (RHA) was used as a reinforcing filler in epoxidized natural rubber (ENR) with various loading levels (0, 10, 20, and 30 phr), and silica filled ENR was also studied for comparison. The effects of RHA content on cure characteristics, mechanical properties, dynamic mechanical properties, and thermoelastic…
Antibacterial Activity and Cytocompatibility of PLGA/CuO Hybrid Nanofiber Scaffolds Prepared by Electrospinning
The PLGA/CuO hybrid nanofibers scaffolds were prepared via electrospinning technique. The presence of CuO in the PLGA scaffolds was confirmed by transmission electron microscope (TEM) and X‐ray photoelectron spectroscopy (XPS). The scaffolds were subjected to various antibacterial and cytobiocompatibility tests. The r…
