Introduction Over the past decades, mesoporous silica materials with special morphology, such as hollow, core-shell, and rattle-type structures, have attracted increasing attention for chemists and materials scientists [1–3].
Typically, the chemical components of shell and core materials in a rattle-type structure are different, and thus interesting properties can be derived from these materials.

Synthesis of Low Fouling Porous Polymeric Membranes Heru Susantoa, Dwi Putri Julyanti, Anis Roihatin Membrane Research Group, Department of Chemical Engineering, Faculty of Engineering, Diponegoro University Jl.
At present, most of commercial membranes are made of polymers because a very wide variety of barrier structures can be realized with this group of materials.
In these regards, polyethylene glycol (PEG), zwitterionic moieties and material that display “kosmotropes” were identified as the non-fouling materials.
As the most commonly used additives, these materials often have various functions such as increasing water permeability as well as fouling resistance.
The authors thank to the Faculty of Engineering, Diponegoro University, for the financial support.

Introduction to Investigation and Appraisal for Building Safety Project of Primary and Secondary School in Yunnan Province Wen Pan1, a, Yu Bai 1, b and Zhong Tao 1, c 1Faculty of Civil Engineering and Architecture, Kunming University of Science and Technology, Kunming, 650051, P.
However, the key point in this investigation step is to identify correctly the buildings belong to Grade A and D, for other two grades would go into further appraisal procedure and get more exact result.
Noticed the fact that there are many differences between codes for design and for appraisal, Executive Regulations for Investigation and Appraisal of Safety Project for Primary and Secondary School Buildings in Yunnan Province recommends the method for utilization of software based on current seismic design code to do appraisal, such as the adjustment of seismic factors and strength of materials, etc.

Developing of a Lubricant Oil for the Ship Gas Turbine of Reducer Huang Fu-chuana,b, Tang Xing-zhonga, Su Man-ronga, Lu Zhao-xiaa, Xiao You-chenga, Li Shenga aGuangxi University, Nanning 530004, China bGuangxi Key Laboratory of Petrochemical Resource Processing and process intensification Technology Keywords: Marine gas turbine; Reducer; Lubricants; Anti-wear Abstract.
Since the ship gas turbine reducer bearings and gear must be able to withstand extremely severe stress level for a long time, the senior engineer status of state work.
Due to gas generator lubricating oil as a high temperature lubricating materials need to work a long time, a long time work at high temperature metal surface and strong oxygen conditions, oxidation stability become a very important performance.
(1) Metal passivation agent Due to ship gas turbine reducer bearing and gears are made in high temperature alloy materials, at high temperatures, may become catalyst to the oxidation of lubricating oil.

Avoiding excess bainite formation, learnt through simulation and dilatometric measurements, is essential and therefore austenite decomposition rate and characteristics in the bainitic range hold key to optimized process design, the details of which are described elsewhere [7].
The potential of steel as light-weight material was further demonstrated in the development of low alloyed TRIP steels [8].
Summary Physical simulation has been effectively employed to generate relevant material data for improved modeling of microstructural phenomena and thermomechanically controlled processes during the development of advanced high strength steel types.
