Targeted proteins for diabetes drug design
Type 2 diabetes mellitus is a common metabolism disorder characterized by high glucose in the bloodstream, especially in the case of insulin resistance and relative insulin deficiency. Nowadays, it is very common in middle-aged people and involves such dangerous symptoms as increasing risk of stroke, obesity and heart failure. In Vietnam, besides the common treatment of insulin injection, some her...... hiện toàn bộ

Rich variety of substrates for surface enhanced Raman spectroscopy
The efficiency of the application of surface enhanced Raman spectroscopy (SERS) technique to each specified purpose significantly depends on the choice of the SERS substrate with an appropriate structure as well as on its performance. Until the present time a rich variety of SERS substrates was fabricated. They can be classified according to their structures. The present work is a review of ...... hiện toàn bộ

Endophytic synthesis of silver chloride nanoparticles from Penicillium sp. of Calophyllum apetalum
In the present study, Penicillium species extract isolated from Calophyllum apetalum was used for the synthesis of silver nanoparticles and it was confirmed by changing the color of the silver nitrate UV–Vis spectrum. The synthesized nanoparticles have been characterized by biophysical techniques such as scanning electron microscopy and x-ray diffraction

Nanostructured polyaniline rice husk composite as adsorption materials synthesized by different methods
Composites based on polyaniline (PANi) and rice husk (RH) were prepared by two methods: the first one was chemical method by combining RH contained in acid medium and aniline using ammonium persulfate as an oxidation agent and the second one was that of soaking RH into PANi solution. The presence of PANi combined with RH to form nanocomposite was clearly demonstrated by infrared (IR) spectra...... hiện toàn bộ

Synthesis and characterization of Fe-doped TiO2 photocatalyst by the sol–gel method
Thin layers of pure TiO2 and TiO2 doped by different amounts of Fe2O3 have been prepared by the sol–gel method with tetraisopropyl orthotitanate and Fe(NO3)3. Physico-chemical properties of catalysts were characterized by BET Adsorption, x-ray Diffraction (XRD), FE-SEM, as well as Raman and UV-Vis spectroscopy. The photocatalytic activity of the obtained material...... hiện toàn bộ

Design and screening of synergistic blends of SiO2 nanoparticles and surfactants for enhanced oil recovery in high-temperature reservoirs
SiO2 nanoparticles (NPs) were synthesized by the sol–gel method in an ultrasound reactor and monodispersed NPs with an average particle size of 10–12 nm were obtained. The synergy occurring in blending NPs and anionic surfactant solutions was identified by ultra-low interfacial tension (IFT) reduction measured by a spinning drop tensiometer (Temco500). The oil displacement efficiency of the s...... hiện toàn bộ

Synthesis and properties of nickel-doped Li4Ti5O12/C nano-composite: an anode for lithium ion batteries
Composite of nickel-doped Li4Ti5O12 and carbon (designated as Ni–Li4Ti5O12/C) is synthesized by solid-state reaction with sucrose added as the conductive carbon source. For comparison, nickel-doped Li4Ti5O12 (designated as Ni–Li4Ti5O12) is obtained under similar conditions. Both materials are characterized by x-ray diffraction, scanning electron microscopy, energy-dispersive x-ray ...... hiện toàn bộ

Silver nanoparticles ink synthesis for conductive patterns fabrication using inkjet printing technology*
In this paper we present silver nanoparticles ink synthesis targeting conductive patterns for micro fabricated devices by inkjet printing technology. The well dispersed nanoparticles ink was composed of silver colloid with an average particle diameter less than 10 nm. These nanoparticles were protected by a capping layer of poly(N-vinylpyrrolidone) (PVP) even at silver concentration of 20 wt...... hiện toàn bộ
