Ag/Ag3PO4-doped BiPO4 heterostructures and their photocatalytic applications under visible light irradiation

Chen Y.J., Tseng C.-S., Tseng P.-J., Huang C.W., Tseng C.-S., Tseng P.-J., Wu M.-Y., Wu T.H., Lai C.-Y., Wu M.-Y., Wu T.H., Lin Y-W, National Changhua University of Education, TW

Ag/Ag3PO4-doped BiPO4 (Ag/Ag3PO4/BiPO4) heterostructures were synthesized by the hydrothermal method combined with the sonochemical process. Powder X-ray diffractometry, UV–Vis diffuse reflectance spectroscopy, Raman spectroscopy, and transmission electron microscopy were used to characterize the heterostructures. The [...]

Removal of Water Contaminants Using Nanotechnology

Yu Z., Li Z., California State Polytechnic University, Pomona, US

Propanil, Diuron, Simazine, and Metolachlor are widely used as herbicides and pesticides in California agriculture and across the U.S., and are considered to pose a significant threat to water contamination by transporting chemicals into surface [...]

Catalytic activity of Cu-CeO2-ZrO2 for biodiesel production

Wongvitvichot W., Jampa S., Luengnaruemitchai A., Chaisuwan T., Wongkasemjit S., Chulalongkorn University, TH

Ceria-Zirconia (CeO2-ZrO2, CZ) was synthesized using two different methods, coprecipitation (copre) and nanocasting (nanocast), for using as support material for copper (Cu) catalyst. Cu-CeO2-ZrO2 (CuCZ) was applied for esterification reaction in biodiesel production. Structure and [...]

Production of Bioabsorbible Nanoparticles of Polycaprolactone by Using a Recirculating System

Colmenares G., Agudelo L., Pinal R., Hoyos L., Universidad Pontificia Bolivariana, CO

Encapsulation and controlled release of substances using polymeric nanoparticles require that these have a high reproducibility, homogeneity, and control over their properties, especially when they are to be used in medical, pharmaceutical or food applications [...]

Uniform Spray-based Large Area Nanoparticle Coating at Nanometric Thickness

Rukosuyev M., Lee P-C, Jun M.B.G., Purdue University, US

Nanoparticle deposition or coatings have drawn significant attention of many researchers and companies because of their potential use in a broad range of applications. For example, nanoparticle coatings can be used to create conductive, catalytic, [...]

Numerical and Experimental Investigation in Replicating a Micro-Featured Surface with the Injection Molding Process

Rajhi A., Jaafar I.H., Coulter J.P., Lehigh University, US

This paper describes current efforts to numerically and experimentally investigate micro and nanoscale features replication using the injection molding process. A silicon (Si) insert with micro–features is fabricated via photolithography followed by deep reactive ion [...]

Fabrication of Polymeric Membranes with Micro and Nano Apertures over Large Areas

Li K., Hernández-Castro J.A., Veres T., National Research Council of Canada, CA

Micro- and nano-porous membranes have a wide range of applications including plasmonics, data storage, and energy devices, as well as biomedical devices. Most of them use Si, SiN, or highly periodic anodic alumina membranes. They [...]

Feedback Process Control for Nano-manufacturing of Semi-conductor Circuits

Kohn W., Zabinsky Z.B., Atigeo, LLC and CUNY Graduate Center, Computer Science Department, US

We develop a feedback process control to realize 3-D circuits with a 2 to 4 nanometer footprint, using a heavily modified ink-jet based nano-manufacturing facility that includes actuator controls driven by pulsed femto lasers. At [...]

Mobility Enhancement from Process-Induced Stress of T-FinFET and Compact Model Development

He J., Peking University Shenzhen SoC Key Lab., CN

It is an often measure that the process-induced stress has been used in advanced CMOS process platform to increase the carrier mobility so to enhance MOSFET performance. It has also a strong effect on the [...]

Synthesis By Two-step Growth Scheme For Fabrication of Hierarchical Micro/Nano-structured Mesoporous FePO4 Particles for High Performance Lithium-Ion Batteries

Dong B., Li G., Yang X., University of Nottingham Ningbo China, CN

Olivine lithium iron phosphate (LiFePO4) has been considered as a promising cathode material in fabrication of lithium ion battery because of its features of low cost, lower toxicity, higher stability, excellent capacity retention, extremely flat [...]
