Synthesis and characterization of La0.75Sr0.25Cr0.5Mn0.5O3- nanoparticles using combustion method

Reddy Channu V.S., Holze R., Walker Jr. E.H., Kalluru R.R., Technische universtat of Chemnitz, DE

La0.75Sr0.25Cr0.5Mn0.5O3-δ (LSCM) perovskite phase nanoparticles were successfully synthesized by solution combustion method using different carriers (NTP, oxalic acid, and citric acid) after calcination of fired gel at 1200 ºC for 7h. Scanning electron microscopy (SEM) [...]

siRNA Delivery Using Biodegradable Nanoparticles for Breast Cancer Therapy

Abbasi S., Arghya P., Afshan K., Prakash S., McGill University, CA

Polyethylenimine (PEI)-coated human serum albumin (HSA) nanoparticles form suitable biocompatible carriers for therapeutic molecules. Small interfering RNA (siRNA) molecules have suggested great promise as a future therapy for breast cancer. In order to overcome the [...]

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 [...]

Analysis of Membrane Filtration Efficiency in Removal of Metal Oxide Nanoparticles from Aqueous Nanoparticle Suspension in the Presence of Coagulation Pretreatment

Surawanvijit S., Kim M., Cohen Y., University of California, Los Angeles, US

The introduction of nanoparticles (NPs) into aqueous environment is expected to rise with increased manufacturing and use of nanoparticles. There is a need to identify efficient and methods for NP removal and such methods must [...]

Semiconductor Oxide Nanoparticles

Sharma A., Sharma R., Sharma A., Sharma R., Sharma A., Sharma R., AKG College of Engineering, IN
