Preparation of Ag/TiO2/bamboo charcoal composite based on chemical and electrochemical synthesis: characterization and antibacterial study

Pookboonmee S., Laohhasurayotin K., National Science and Technology Development Agency, TH

A combined function of photocatalysis, antibacterial, and adsorption was introduced as a composite powder in the form of Ag/TiO2/BC. The powder was characterized by SEM, TEM, and XRD for confirmation of the obtained product. The [...]

A Study on Fabrication of Cellulose Nanofibers in Water

Kim K-Y, Jeong W.-Y., Lim D.-Y., Korea Institute of Industrial Technology, KR

Cellulose nanofibers (CNFs) were successfully fabricated by fibrillation of wood pulp cellulose into submicron and/or nanoscale nanofibers with a microfluidizer in water solution. CNFs have the great potential as reinforcing materials for polymeric composite materials. [...]

Fabrication and Characterization of pH-Responsive, Nanoparticle-Attached Porphyrins for Singlet Oxygen Production

Li W., Courtney S., Gandra N., Ellis E.D., Tiyyagura P.T., Gao R., Jackson State University, US

The goal of this work was to understand if singlet oxygen (1O2) production from an immobilized dye could be regulated directly on support media such as titania and silica. Two types of pH- responsive, nanoparticle-attached [...]

Role of Hard Segment Induced Nanosized Domain on Concentrated Solutions and Bulk Properties

Lem K.W., Lee D.S., Haw J.R., Song G.S., Curran S., Sund S., Iqbal Z., Brumlik C., Konkuk University, KR

When a film is cast from solution, the volume fraction of polymer in the film increases with increasing drying temperature and/or time. Its viscoelastic behavior transitions from more viscous (where G” > G’) in dilution [...]

Microstructure and tribological properties of CrTiAlN nanoscale composite coatings on 65Mn steels deposited by multi arc ion plating technology

Cai Z., Zhang P., Academy of Armored Force Engineering, CN

In order to improve the life of piston rings, a multicomponent CrTiAlN composite coatings with different chemical composition are deposited on the surface of 65Mn steels by multi-ion plating technology in a gas mixture of [...]

Nano-imprinting technology applied in pentacene films

Chang M-H, Chou W-Y, National Cheng Kung University, TW

The control of polymorphism in organic semiconductor films has attracted considerable interest for improvement in the device performance. In the present study, nano-imprinting technology is used to control polymorphism in pentacene film. Furthermore, we demonstrate [...]
