Here we have demonstrated a solventless plasma-based process that integrates low-cost, high throughput, high reproducibility and ecofriendly process for the functionalization of the next-generation point-of-care device platforms. Amine functionalities were deposited by plasma-enhanced chemical vapour deposition (PECVD) using a new precursor. The influence of the plasma RF power and the depositi...

The research of organoclays has been occurring for many years to develop and add value these inorganic materials several industrial applications, such as pollutant absorbers or impermeable plastics. organoclay applications are intrinsically related organo-modification the structure clays. This study shows preparation characterization produced by a nontronite type clay (calcic bentonite) from To...

The need to increase the productivity and capacity of power transformers has conditioned production insulating papers a higher thermal class. For this purpose, various techniques solid insulation modification were applied, which enable in chemical stability paper during operation transformer. applied additives, primarily dicyandiamide (DICY) polyacrylamide (PAM), are one form cellulose final st...

It is well known that small amount Piperazine (PZ) enhance the CO2 absorption properties of tertiary amine aqueous solution. Because the tert-amine has the lower heat of reaction, the blended amine solution, tert-amine with PZ, is attractive for low energy absorbent. There are some reports about the investigation of the mechanism of the blended amine solution, however, there still a difficulty ...

Chemical modification of proteins is essential for a variety of important diagnostic and therapeutic applications. Many strategies developed to date lack chemo- and regioselectivity as well as result in non-native linkages that may suffer from instability in vivo and adversely affect the protein's structure and function. We describe here the reaction of N-nucleophiles with the amino acid dehydr...

sulfur mustard (sm, bis- (2-chloroethyl) sulphide) is a chemical warfare agent that causes dna alkylation, protein modification and membrane damage. sm can trigger several molecular pathways involved in inflammation and oxidative stress, which cause cell necrosis and apoptosis, and loss of cells integrity and function. epigenetic regulation of gene expression is a growing research topic and is ...

Microwave-assisted synthetic pathway was explored for the sustainable esterification of cellulose nanofibers (CNFs) using an aromatic amine compound. For this purpose, were isolated from unbleached and bleached eucalyptus pulp through homogenization process. The chemical composition, structural properties, morphology, thermal properties extracted investigated. para-aminobenzoic acid (PABA) empl...

In a preliminary study we demonstrated that the formation of the epidermal growth factor (EGF) receptor-ligand complex requires the participation of the highly conserved arginine 41 side chain of the growth factor peptide (Engler, D.A., Montelione, G.T., and Niyogi, S.K. (1990) FEBS Lett. 271, 47-50). In an attempt to gain further insight into the nature of this interaction(s), we used both sit...

in this paper, we report on the synthesis of cu nanoparticles through a single-precursor route by controlling the growth temperature. selective adsorption of oleylamine on various crystal planes may play an important role in the growth process. the understanding of this self-assembling process will help us develop reliable and reproducible methods to synthesis other three dimensional nanostruct...

Amine-modified mesoporous SBA-15 adsorbent has been prepared by impregnation method using tetraethylenepentamine. The samples of this modified SBA-15 have been characterized by small angle X-ray scattering (SAXS), Scanning electron microscopy (SEM), Nitrogen adsorption-desorption isotherm and FT-IR. The adsorption capacity of CO2 on unmodified and modified samples were measured at high pressure...
