Preparation and application of silver/chitosan-sepiolite materials with antimicrobial activities and low cytotoxicity.

Antimicrobial materials can prevent microbial infection and affect the beauty and structure of interior walls. Herein, a hybrid material silver/chitosan-sepiolite (Ag/5CTs-Sep) with antimicrobial activities was prepared via impregnation. Its antimicrobial properties were investigated via the disk diffusion method.

Preparation of organic-inorganic chitosan@silver/sepiolite composites with high synergistic antibacterial activity and stability.

Organic-inorganic antibacterial materials chitosan@silver/sepiolite (CTs@Ag/Sep) was prepared by grafting organometallic chelate of chitosan and silver on sepiolite. The prepared samples were characterized, and their antibacterial properties were detected. The carrier sepiolite was beneficial for the thermal stability of the composite material.

Different Crystal Form Titania Supported Ruthenium Nanoparticles for Liquid Phase Hydrodeoxygenation of Guaiacol.

Titania supported Ruthenium-based catalysts were prepared for liquid phase hydrodeoxygenation of guaiacol to cyclohexanol. The catalytic performance is affected by the different crystal forms of titania supports. Anatase and rutile titania supported catalyst 5%Ru/a-r-TiO2 presents higher BET surface area, better dispersion of Ru particles with smaller particle size of 3-4 nm, more acidic centers, and more Ruδ+ located at the boundary between anatase titania and rutile titania.

Ti-doped α-FeO nanorods with controllable morphology by carbon layer coating for enhanced photoelectrochemical water oxidation.

Ti-doped α-FeO nanorods (NRs) with carbon layer coating were fabricated for photoelectrochemical (PEC) water oxidation. The α-FeO NRs were grown on the surface of a Ti foil substrate by hydrothermal synthesis. Ti was diffused from the Ti substrate and doped into the α-FeO NRs by sintering at 800 °C.

Boosting one-step conversion of cyclohexane to adipic acid by NO2 and VPO composite catalysts.

We demonstrate VPO composites as efficient catalysts for highly selective oxidation of cyclohexane to adipic acid with NO2. In particular, the Ni-Al-VPO composite catalyst exhibits the striking conversion of cyclohexane (60.6%) and exceptionally high selectivity towards adipic acid (85.

Study on the resonance light-scattering spectrum of anionic dye xylenol orange-cetyltrimethylammonium-nucleic acids system and determination of nucleic acids at nanogram levels.

The interaction of xylenol orange (XO) and nucleic acids in the presence of cetyltrimethylammonium bromide (CTMAB) in aqueous solution has been studied by a resonance light-scattering (RLS) technique with a common spectrofluorometer. In hexamethylenetetramine (HMTA) buffer (pH7.30), XO and nucleic acids react with cetyltrimethylammonium bromide to form large particles of three-component complex, which results in strong enhanced RLS signals characterized by three peaks at 295.

Study on bromocresol green-cetyltrimethylammonium-deoxyribonucleic acids system by resonance light scattering spectrum methods.

An assay of deoxyribonucleic acids (DNA) determination, with the sensitivity at nanogram level, was established in the present study by using a common spectrofluorometer to detect the intensity of resonance light scattering (RLS). In hexamethylene tetramine (HMTA) buffer (pH 11.00), Bromocresol Green (BCG) and deoxyribonucleic acids (DNA) react with cetyltrimethylammonium bromide (CTMAB) to form large particles of three-component complex, which results in strong enhanced RLS signals characterized by three peaks at 336, 390, and 622 nm and at 336 nm that is the strongest of the three enhanced RLS peaks.
