HDA-capped ZnO nanoparticles were prepared by solvothermal method using solvents of different polarities. A number of parameters were kept constant such as temperature, pressure, time, and pH while solvents were varied, that is, water, ethanol, and acetone. The TEM was used for the structural properties and morphologi…
Microparticles of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and poly(ε-caprolactone) (PCL) containing resveratrol were successfully prepared by simple emulsion/solvent evaporation. All formulations showed suitable encapsulation efficiency values higher than 80%. PHBV microparticles revealed spherical shape w…
The chemistry of organoimido derivatives of polyoxometalates (POMs) has received increasing interest. In recent decades, a great development of the synthetic chemistry of organoimido derivatives of POMs using different imido-releasing reagents has taken place, particularly the novel DCC-dehydrating protocol to prepare…
A green approach for the electrochemical exfoliation of graphite to graphene is reported. After the exfoliation of graphite, the 9-anthracene carboxylate ion (ACA), which was used as an electrolyte, was adsorbed on the surface of graphene through noncovalent interaction. X-ray diffraction analysis confirms the exfolia…
The self-assembly of [Fe(III)(Tp)(CN)(3)](-) and [Fe(II)(bik)(2)(S)(2)](2+) affords the cyanide-bridged mixed valence {Fe(III)(2)Fe(II)(2)}(2+) molecular square, which exhibits a photomagnetic effect under laser light irradiation at low temperature and also shows thermal spin-state conversion near ambient temperature.
The mechanochemical click coupling of isothiocyanates and amines has been used as a model reaction to demonstrate that the concept of a solvent-free research laboratory, which eliminates the use of bulk solvents for either chemical synthesis or structural characterization, is applicable to the synthesis of small organ…
Polycrystalline CoFe2O4 was produced by a ceramic method. The heat-treated powder was pressed, varying the hydrostatic pressure between 87 and 278 MPa, and was heat-treated again at 1350 °C for 24 h. All magnetic parameters showed a clear dependence on this hydrostatic pressure. The saturation magnetization showed a m…
Recent work on the precipitation of the mineral gypsum (calcium sulfate dihydrate) has shown that contrary to long-standing opinion, this phase can precipitate from solution at room temperature via a bassanite (calcium sulfate hemihydrate, or plaster of Paris) intermediate phase. An amorphous calcium sulfate (ACS) pha…
A microemulsion-mediated hydrothermal method has been demonstrated for synthesizing ZnSe and Fe-doped ZnSe quantum dots (QDs). The properties of ZnSe QDs can be controlled by using the surfactants of polyoxyethylene lauryl ether and Triton X-100. The resulting QDs were found to be in a zinc blende crystal structure, w…
Materials are precious resources. Different methods are employed to protect the material from degradation. Thermal spraying is one of the most effective method to protect the material from wear, high temperature corrosion, stresses and erosion, thus increasing the life of material in use. Detonation gun spraying is on…
Polylactic-co-glycolic acid (PLGA) based nanoparticles are biocompatible and biodegradable and therefore have been extensively investigated as therapeutic carriers. Here, we engineered diagnostically active PLGA nanoparticles that incorporate high payloads of nanocrystals into their core for tunable bioimaging feature…
Nanoparticles are becoming frequently used in the research area of creating functional surfaces because they can be more versatile than just making dimensions smaller. Particularly, a variety of nanoparticles have been applied for the construction of superhydrophobic and superhydrophilic surfaces with micro- and nano-…
Biologically synthesised nanoparticles with distinct shapes and sizes have found tremendous breakthroughs and fondness in various fields of therapeutic and diagnostic applications. In this study, size-controlled green synthesis of silver nanoparticles (Ag-NPs) was performed using Bacillus licheniformis kk2 by response…
In a view to reduce the cost of production and the harmful destruction in normal environment, there's a lot of research have been conducted or still ongoing for the possibility of using natural fibers which are wholly degradable in the combination of biodegradable thermoplastic materials. This research will focus on K…
The development of reliable, eco-friendly processes for the synthesis of nanoscale materials is an important aspect of nanotechnology. Silver bionanoparticles have been known to have inhibitory and bactericidal effects. In the present study, authors report the extracellular synthesis of nanoparticles of silver by redu…
Motivated by the recent quest for producing novel two dimensional nanomaterials, we developed a facile synthetic method for growing boron nitride–carbon (BN–C) phase-separated composite nanosheet coatings on silicon/silicon dioxide (Si/SiO2) substrates. The coatings were composed of compact partially vertically aligne…
The syntheses of new fatty acid-derived amine functional monomers via the thiol–ene addition reaction as well as the thereof derived renewable polyamides were investigated. The thiol–ene addition of cysteamine hydrochloride to the double bonds of methyl 10-undecenoate, methyl oleate, and methyl erucate yielded heterod…
The study of coating carbon nanotubes with metal/oxides nanoparticles is now becoming a promising and challenging area of research. To optimize the use of carbon nanotubes in various applications, it is necessary to attach functional groups or other nanostructures to their surface. The combination of the distinctive p…
Carbon nanodots (C-Dots) have attracted growing interest in recent years due to their low cost, ready scalability, excellent chemical stability, biocompatibility, colloidal stability, and resilience of photoluminescence. They have been employed as novel, ideal fluorescent probes for bio-imaging and smart sensing. In a…
