Ultraviolet Light (UV)-Induced Photocatalytic Degradation of Diclofenac Using Naturally Derived TiO2@rGO Composite

Lorenz E. Borromeo, Lea P. Bongat, John Patrick S. Nunez, Kirby F. Mendioro, Jocelyn R. Balisnomo
Diclofenac (DCF) is a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain in joint-related diseases. It is not completely metabolized after consumption and cannot be easily removed using conventional wastewater treatment. DCF has been detected in water bodies and may pose chronic effects on the endocrines of living organisms even at low-level exposure. Heterogeneous photocatalysis provides an alternative and efficient method of degrading DCF. In this study, the photocatalytic remov...

Evaluation of Laser-Heating and Laser-Reheating of Sunflower (Helianthus annuus) Seed Oil Quality

Alaa Ahmed Mudawi, Ali A. S. Marouf
This paper focuses on the difference between the effect of heating and reheating on sunflower oil properties by using carbon dioxide laser and electrical heater. Two samples of sunflower oil were heated and reheated with carbon dioxide laser beaming up to 50°C, which takes 30 minutes; another two samples were heated and reheated up to 250°C using electrical heater in two minutes, along with an unheated control sample at ambient conditions. Chemical properties like acid value, free fatty ...

Static IR Drop Estimation on the Power Network

S. S. Abazyan, N. E. Mamikonyan
This paper presents a power consumption estimation algorithm for static analysis. IR drop is being calculated for each separated node, which makes this algorithm favorable for IR drop calculation on infinite power network. The power consumption is being calculated using random walk algorithm, which includes Monte Carlo simulation method for increasing accuracy of estimation. For power mesh with 150 k power nodes, total IR drop cal

Electronic Transport Mechanisms in PVDF/ZnO Nanocomposite Films

Bir B. Bohara, Ashok K. Batra, James R. Currie Jr.
In this report, we present fundamental DC conduction mechanisms of pol-yvinyl difluoride/nano-zinc oxide (PVDF/ZnO) composite films. Nano-composite films of zinc oxide in the PVDF matrix have been fabricated via a solution casting method. Space charge limited conduction (SCLC) was found to be a prominent conduction mechanism in higher voltage region and Schottky- Richardson mechanism was a possible conduction mechanism in a higher

The Cooperative Effect of BSA Langmuir Monolayers and Magnesium Ions on Calcium Carbonate Crystallization

Zhonghui Xue, Ning Xue
The crystallization of calcium carbonate at interface of Langmuir monolayers of bovine serum albumin and subphase containing magnesium ions was studied in this paper. The results were characterized by using powder X-ray diffraction (XRD) and scanning electron microscopy (SEM). The effect rules were obtained by the cooperation of bovine serum albumin Langmuir monolayers and magnesium ions. BSA Langmuir monolayers controlled calcium

Electronic Properties of Mo(1﹣x)W(x)S2-Ni Grown over Graphene

D. H. Galvan, J. Antunez-Garcia, S. Fuentes, M. Shelyapina
A proposal of the theoretical adsorption of 2H-Mo(1﹣x)W(x)S2-Ni over graphene using extended Hückel tight-binding method was investigated. It is well known that a theoretical prior investigation is well accepted by the scientific community due to that provides information regarding elec

Effect of Substrate Temperature on Structural and Optical Properties of Au/SiO2 Nanocomposite Films Prepared by RF Magnetron Sputtering

Ahmed Belahmar, Ali Chouiyakh
Silica films containing gold nanoparticles were grown by magnetron radio frequency (rf) sputtering technique under various deposition conditions. The structural and optical properties of the composite films deposited at 400℃ substrate temperature were compared with those deposited at room temperature. Effect of substrate temperature of AuNPs on micro structural properties of the Au/SiO2

Synthesis and Characterization of Carbon Nanospheres

Priya Karna, Madhav Ghimire, Sanjay Mishra, Sunil Karna
An experiment was conducted to synthesize carbon nanospheres of different sizes by controlling the temperature in polycondensation reactions of glucose under hydrothermal processes. Morphological, structural, thermal, and optical properties of as-synthesized particles were characterized using a transmission electron microscope (TEM), scanning electron microscope (SEM), X-ray diffractometer (XRD), thermal gravimetric analysis (TGA)

Hydrogen Storage in VNx-Hy Thin Films

Viktor Bryk, Aleksey Guglya, Aleksandr Kalchenko, Ivan Marchenko, Yuriy Marchenko, Elena Solopikhina Melnikova, Victor Vlasov, Evgeniy Zubarev
Vanadium or its alloy-based hydrides are intensively studied at the moment with regard to their use as hydrogen absorbents. Most experiments were carried out using “bulk” materials. This paper uses ion beam-assisted deposition technology (IBAD) to create thin-film nanocrystalline VNx-Hy hydrogen storages. The transmission electron microscopy and scanning electron microscopy were used to study the initial stages of the film formation. The main mechanisms of the formation of ...

Endostatin-Encapsulated N-Succinyl-Chitosan Nanoparticles Inhabited the Growth of MCF-7 Cell

Yanrong Fan, Ye Li, Xuefei Xia
A simple method was developed to synthesize the N-succinyl-chitosan (NSC) successfully. NSC was characterized by FTIR, 1H NMR and element analysis. The NSC can form nanoparticles with TPP through electrostatic interaction. The morphology, particle size and zeta potential of the nanoparticle were investigated and showed a 100 - 200 nm in diameter with a positive potential 9.99 mv. The encapsulation efficiency of NSC-ES-NPs was 94.76 ± 0.05. The in vitro cell culture indicates th...
