Nanocomposite of ZrO2/ZnO was prepared under ultrasonic irradiation by sol gel process from directly mixing Zirconium and Zinc gels. The mixture was placed under ultrasonic irradiation for 2 hours. After the aging time and filtration of the reaction mixture, the filtrated composite gel was calcinated at 500 °C for 3h in furnace. The precursor gels of zirconium and zinc were prepared ...

Phenol (87.3 mg/l), p-cresol (58.6 mg/l), o-cresol (76.9 mg/l), and 2,5-xylenol (36.7 mg/l) were detected in the urine of workers employed in the distillation of the high temperature phenolic fraction of tar (carbolic oil). The concentrations of these compounds in the urine of non-exposed male workers was 11.7 mg/l, 25.7 mg/l, 68.1 micrograms/l, and 69 micrograms/l respectively. The excretion r...

The structure of 4-methylphenol (p-cresol) and its binary water cluster have been elucidated by rotationally resolved laser-induced fluorescence spectroscopy. The electronic origins of the monomer and the cluster are split into four sub-bands by the internal rotation of the methyl group and of the hydroxy group in case of the monomer, and the water moiety in case of the cluster. From the rotati...

A simple method to immobilize poly(neutral red) (PNR) and flavin adenine dinucleotide (FAD) hybrid film (PNR/FAD) by cyclic voltammetry is proposed. The PNR/FAD hybrid film can be easily prepared on an electrode surface involving electropolymerization of neutral red (NR) monomers and the electrostatic interaction between the positively charged PNR and the negatively charged FAD. It exhibits ele...

The development of modern therapeutics has raised the requirement for controlled drug delivery system which is able to efficiently encapsulate bioactive agents and achieve their release at a desired rate satisfying the need of the practical system. In this study, two kind of aqueous model drugs with different molecule weight, Congo red and albumin from bovine serum (BSA) were nano-encapsulated ...

The great demand for long-wavelength and high signal-to-noise Ca(2+) indicators has led us to develop CaRuby-Nano, a new functionalizable red calcium indicator with nanomolar affinity for use in cell biology and neuroscience research. In addition, we generated CaRuby-Nano dextran conjugates and an AM-ester variant for bulk loading of tissue. We tested the new indicator using in vitro and in viv...

Presently the majority of tissue engineering approaches aimed at regenerating bone relies only on post-implantation vascularization. Strategies that include seeding endothelial cells (ECs) on biomaterials and promoting their adhesion, migration and functionality might be a solution for the formation of vascularized bone. Nano/micro-fiber-combined scaffolds have an innovative structure, inspired...

Poly(2,5 dimethoxyaniline) and Platinum (PDMA@ Pt) nanocomposite electrode was fabricated by the electrochemical method. PDMA@ Pt nano electrocatalyst size is around 150-200 nm. having electrocatalytic activity towards methanol oxidation reaction.

It is assumed that each nano-robot has a 0.1μm3 tankage which is far smaller than the volume of a human red blood cell (i.e. 1.12× 102 μm3)[6]. Thus, the nano-machines are non-invasive for biomedical applications, such as drug delivery and disease diagnosis. Since the nano-machine has an initial source of 108 molecules in its own tankage and since the throughput of the DMC systems is significan...

Reduced graphene oxide/poly (ionic liquid) functionalized nano-fibrillated cellulose composite paper with significant enhancement of mechanical strength, ductility, toughness and hydrophobicity was fabricated by vacuum filtration assisted assembly.
