Visible Light Active Phosphorus-Doped TiO2 Nanoparticles: An EPR Evidence for the Enhanced Charge Separation
Phosphorus-doped TiO2 nanoparticles with visible light activity were prepared by sol–gel method by using Ti(IV) isopropoxide and phosphoric acid as precursors. As prepared samples were calcined at… Expand

It is concluded that occupational cement hand dermatitis is an important and severe issue in Taiwan, and the most common allergens among cement workers are potassium dichromate, thiuram mix, fragrance mix and cobalt chloride. Expand
Characteristics of Air Pollutants and Assessment of Potential Exposure in Spa Centers During Aromatherapy
Abstract This study investigated the secondary organic aerosols (SOAs) formation capability of various fragrant and Chinese herbal essential oils in the presence of ozone in a controlled-environment… Expand
Comparison of Chinese Herbal Oils and Lemon Oil for Formation of Secondary Organic Aerosol
Several studies reported that evaporation of fragrant essential oils in an indoor environment may cause the emission of secondary organic aerosols (SOAs). However, the tendency of forming SOAs from… Expand

The multiple regression analysis showed that the use of gloves may reduce significantly the chromium exposure, and total body burden of chromium are higher among cement workers with skin disease and smoking habit. Expand
Effect of hand dermatitis on the total body burden of chromium after ferrous sulfate application in cement among cement workers
The effect of dermatitis on the total uptake of chromium in cement with or without FeSO4 has not been previously explored, andFerrous sulfate added to cement has been used to reduce the prevalence of dermatritis in workers. Expand

Oxidation of reduced TiO(2) apparently is a simple low-cost and promising route for improving the photoactivity of TiO (2), and this EPR active center is assigned to surface oxygen centered anion radical with two coordinating titaniums. Expand
Synthesis, properties and molecular structures of iron(III), cobalt(II), nickel(II), copper(II), copper(I) and zinc(II) complexes with N,N-bis(pyrazol-1-ylmethyl)benzylamine
A newly prepared ligand, N,N-bis(pyrazol-1-ylmethyl)benzylamine (L) reacted with metal ions to form [FeLCl3], [NiL(NCS)2(MeOH)], [MLX2](M = CoII, CuII or ZnII, X = Cl–, Br– or NCS–) and [(CuLI)2].… Expand
Electron Paramagnetic Resonance Investigation of Charge Transfer in TiO2(B)/Anatase and N–TiO2(B)/Anatase Mixed-Phase Nanowires: The Relative Valence and Conduction Band Edges in the Two Phases
Regarding how photogenerated charge carriers are transferred in TiO2(B)/anatase mixed-phase nanowires, no unified conclusion has been reached. Electron paramagnetic resonance (EPR) spectroscopy is… Expand
Chromium-induced skin damage among Taiwanese cement workers
Skin barrier function of cement workers may have been disrupted by chromium in cement, and smoking might significantly enhance such skin barrier perturbation with chromium exposure, and decreased chromium skin exposure and smoking cessation should be encouraged at work. Expand
