poly(ethylene adipte) and poly(ethylene adipate)/silica nanocomposite (pead/sio2) containing 3 wt. % sio2  were prepared by an in situ method. the examinations on the non-isothermal crystallization kinetic behavior have been conducted by means of differential scanning calorimeter (dsc). the avrami, ozawa, and combined avrami and ozawa equations were applied to describe the crystallization kinet...

With the increasing shortage of timber resources and advancement environmental protection projects, many artificial fast-growing forests are planted used as raw materials in China. There significant differences properties natural forest wood wood, mainly depend on change status bound water cell wall. In this study, fiber saturation point (FSP) pore size distributions within wall six species wer...

Dimerization process is essential for producing copolymers. The features of dimerization process like thermal-oxidative degradation should be well known to reach maximum efficiency and a superior reactor design. Also, the degradation mechanism of biodegradable polymers is important during sterilization processes. Thermal-oxidative degradation of PGA, PLLA, and their binary copolymers was invest...

We described an electrochemical method to monitor in real-time the isothermal helicase-dependent amplification of nucleic acids. The principle of detection is simple and well-adapted to the development of portable, easy-to-use and inexpensive nucleic acids detection technologies. It consists of monitoring a decrease in the electrochemical current response of a reporter DNA intercalating redox p...

This review covers both the history and present state of the kinetics of thermally stimulated reactions in solids. The traditional methodology of kinetic analysis, which is based on ® tting data to reaction models, dates back to the very ® rst isothermal studies. The model ® tting approach suŒers from an inability to determine the reaction model uniquely, and this does not allow reliable mechan...

Abstract The influence of flow configuration on flame-wall interaction (FWI) premixed flames within turbulent boundary layers has been investigated. Direct numerical simulations (DNS) two different configurations for interacting with chemically inert isothermal and adiabatic walls in fully developed have performed. first is an oblique wall (OWI) a V-flame channel the second head-on (HOI) planar...

The green blends of an ionic liquid, 1-ethyl-3-propylimidazolium bis(trifluoromethanesulfonyl) imide {[EPrI][TFSI]}, and a biodegradable polymer, poly(3hydroxybutyrate) (PHB), were investigated in this study. The influence of an ionic liquid on the crystallization behaviors of a biodegradable polymer was explored. In the blends, the presence of [EPrI][TFSI] decreased the Tg and Tm of PHB. Incor...

The statistics of isothermal lines and loops of the cosmic microwave background (CMB) radiation on the sky map is studied and the fractal structure is confirmed in the radiation temperature fluctuation. We estimate the fractal exponents, such as the fractal dimension De of the entire pattern of isothermal lines, the fractal dimension Dc of a single isothermal line, the exponent in Korčak’s law ...

bainitic transformation at low transformation temperatures leads to a microstructure involving fine plates of bainitic ferrite and thin films of retained austenite. this microstructure has shown ultimate tensile strength of about 2.2 gpa, noticeable uniform elongation in the range of 5 to 30%, hardness values of about 600 to 670 hv and impact toughness in the range of 30 to 40 mpa m1/2. with ca...

We developed a new loop-mediated isothermal amplification (LAMP) method to detect rrs, a 16S rRNA gene of pathogenic Leptospira spp. in urine. The method enables detection of two leptospiral cells per reaction mixture following boiling of urine specimens. The sensitivity of this method is higher than that of culture or of flaB nested PCR.
