In this work, gold nanorods (AuNRs) with well-controlled aspect ratios were prepared using a modified seedgrowth method and covered by TiO2 layers through the hydrothermal reaction to improve stability. Integrating TiO2 with plasmonic rod-like gold nanoparticles could enhance their photo activity by the local surface plasmon resonance (LSPR) effect. AuNRs aspect ratios were controlled by varying the amount of seed solution, reducing agents, surfactant (CTAB), and titanium (IV) but oxide.

TiO2 nanocrystal powders have been prepared by sol-gel routes. By controlling pH, TiO2 nanoparticles of sizes ranging from 7 to 14 nm can be synthesized. X-ray diffraction (XRD) analysis indicated that both the anatase and the rutile phase appears in the powder when pH < 2.

In this paper, nickel oxide thin films on the titanium substrate were prepared by the sol-gel dipcoating technique with the precursors NiSO4.7H2O and acetic acid. The obtained thin films have a good adhesion to the substrate. The electrochemical behaviors of the NiOxHy thin films were investigated in KOH 1 M solution by the voltammetry technique. The effect of addition of platinum, heating temperature and the dip coating number on the electrochemical behavior was also investigated. The thin films have high electrochemical properties at 270o C and at third dip coating.

Titanium oxide ST01, ST31, TiO2 catalysts modified by V5+, N2+ and supported on MCM41 and SiO2 have been used for photooxidation of p-xylene in gas phase. Physicochemical properties of catalysts were determined by the methods of BET Adsorption, Xray Diffraction (XRD), UV-Vis spectroscopy, and atom adsorption spectroscopy (AAS) methods. The photocatalytic activity of catalysts were determined after thermal treatment as well as UV lighting. The common observation is that the higher temperature of treatment the lower conversion of p-xylene obtained.

Kem chống nắng bảo vệ nhan sắc Một trong những bí quyết chăm sóc sắc đẹp là dùng kem chống nắng. Thế nhưng, liệu bạn đã thực sự hiểu nó trước khi thoa sản phẩm làm đẹp thiết yếu này lên cơ thể mình? 1. Chỉ số SPF Dù bạn có sử dụng chỉ số chống nắng SPF 50 thì cũng không có nhiều khác biệt so với loại thông thường. Để bảo vệ tốt nhất, chỉ cần loại SPF 30 có chứa oxide kẽm, titanium dioxide hay avobenzone Mexoryl. 2. Bạn cần nhiều hơn bạn nghĩ. Một lọ kem chống nắng cho...

Abstract Red mud is a residue in the production of alumina by the Bayer process. It contains oxides of iron and titanium, and has been shown to be active in sulfided form as hydrogenation catalyst. The evolution of sulfided red mud activity and selectivity with reaction time was studied for the hydrogenation of a light fraction of an anthracene oil.
