Introduction Formaldehyde is one of the most chemicals in the fields of textile industry, leather industry, synthetic chemistry and etc.
Further observe the morphology of the nanofibers obtained at 90 °C, a number of fibers are so slender to coated MnO2 powder and exist the serious blemish, in addition, much conical structure exist in nanofibers obtained at 30°C.

Efficient Synthesis of Functionalized 3-Aminopropanols Xiaochuan Lia, Shanshan Gongb, Qi Sunc,* Jiangxi Key Laboratory of Organic Chemistry, Jiangxi Science and Technology Normal University 605 Fenglin Avenue, Nanchang, Jiangxi 330013, PR China aemail: 985037753@qq.com, bemail: gongshanshan33@gmail.com, cemail:sunqi96@tsinghua.org.cn Keywords: Aminophosphonate; Kabachnik-Fields reaction; Solvent-free; 3-Aminopropanol Abstract.
Introduction α-Aminophosphonates have been found in versatile applications in agricultural, industrial, and medicinal chemistry on the basis of their chemical and biological properties as well as their utility as important synthetic intermediates [1-3].
In polymer chemistry, alkyl diamines and amino alcohols have been widely applied as cross-linking agents in the production of different types of polymers [12-14].
The structures of the α-aminophosphonates were characterized with NMR and MS.

Effect of Surface Modifier on Their Tribological Properties of LaF3 Nanoparticles in Base Oil Guo-Xian Yu, Mei Jin, Kun Wan, Ping Lu* School of Chemistry and Environmental Engineering, Jianghan University, Wuhan 430056, China luping@126.com Key words:Surface modifier; lipophilic chain length; LaF3; nanoparticle; tribological properties Abstract.
It has been indicated that these four modified LaF3 nano-particle samples were quite similar both in morphologic feature and particle size, whereas big gaps were presented in tribological characteristics resulting from different molecular structure.
Based upon the colloid chemistry of surfactants, a surface modifier was easier to be adsorbed on the friction interface in a rather large amount.

In this study, a simple immersion method was introduced to attach the syntesized chiral selector onto the nanoarchitectured structured PDMS surface in order to develop a chiral selective PDMS-BCPA nanomembrane.
The oxidation solution used capable of changing the surface chemistry of PDMS by producing silanol terminations groups (Si-OH) on its surface as illustrated in Fig. 4 followed by surface functionalization using APTES then created a Si-O-Si bond with terminated amine group for effective attachment of BCPA as depicted on Fig. 5.

At the first stage, the porosity increases due to the release of volatile substances (0÷200) ºC, at the second stage (200÷400) ºC as a result of thermal action, the thin-porous structure is compacted (the total volume of micropores and the specific surface area decreases).

The physical-mechanical properties of WPCs depend on the compatibility that depends on interfacial adhesion between a wood filler and a polymer matrix, which represents one of the main problems since wood has a strongly polar structure, but the most polymers are non-polar [2].

It is interpreted as follows: a moderate increase in the SiO2 contents has allowed to decreasing the number of active groups and thereby modified the glass surface chemistry.
It is this surface chemistry alteration which is responsible for the reduction of hydrogen-bonds formation in contact with water because of low surface free energy in the presence of SiO2.
This improvement is attributed to the reduction of active groups on the glass surface, where the SiO2 particulate assisted surface chemistry with low interfacial free energy favoured the formation of hydrogen-bonds in contact with water.
