[Investigation on endemic situation of schistosomiasis in infection-controlled regions in Anhui Province].

Objective: To understand the epidemic situation of schistosomiasis in 27 counties (cities, districts) that reached the criteria of schistosomiasis infection controlled in Anhui Province.

Methods: According to the requirement of The National Assessment Scheme of Schistosomiasis, 81 administrative villages where the schistosomiasis epidemic situation was relatively heaver in above-mentioned 27 counties (1 village per town, 3 towns per county) were sampled and investigated.

Results: From 2012 to 2014, 81 villages were investigated, and 34,293 residents received the serum examinations, and 1,086 were positive with a positive rate of 3.

[Susceptibilities of Oncomelania hupensis snails to Schistosoma japonicum miracidia from different hosts].

Objective: To understand the susceptibilities of Oncomelania hupensis snails to Schistosoma japonicum miracidia from different hosts.

Methods: The Schistosoma japonicum eggs from different hosts, such as rabbits, cattle and mice were collected. These eggs were incubated for miracidia, respectively.

Characterization of partially reduced graphene oxide as room temperature sensor for H2.

Reduced graphene oxide (RGO) was synthesized under H(2)/Ar treatment from 100 °C to 900 °C. RGO-300 shows excellent sensitivity to H(2) and a dual sensing mode was observed. The balance between the chemical adsorption capacity and electronic conductivity, and the dominance of either electrons or holes are the key factors.

Hydrophilic TiO2 porous spheres anchored on hydrophobic polypropylene membrane for wettability induced high photodegrading activities.

TiO(2) porous nanospheres on polypropylene (PP) films (TiO(2)/PP composite) are produced at ambient temperature. Particle/pore size match up is the key anchoring point to overcome the low affinity between hydrophilic materials and hydrophobic materials. With the hydrophilic TiO(2) catalyst evenly dispersed on a hydrophobic surface, the aqueous solution will selectively skip the substrate and wet the catalysts.

Identification of the nitrogen species on N-doped graphene layers and Pt/NG composite catalyst for direct methanol fuel cell.

Heat treatment of graphene oxide (GO) with ammonia flow at various temperatures resulted in different distribution of nitrogen species. Synchrotron based X-ray absorption near-edge structure (XANES) spectroscopy provides unambiguous evidence for the presence of three nitrogen species. The Pt/NG-800 composite exhibits outstanding electrocatalytic activity for methanol oxidation.

Silica nanotubes with mesoporous walls and various internal morphologies using hard/soft dual templates.

Silica nanotubes with mesoporous walls of 30 nm thickness and various internal morphologies are produced using hard/soft dual templates; this hierarchical pore structure shows faster mass transportation in catalysis.
