Chitosan is a naturally derived material that has anti-microbial properties. Studies have shown that chitosan is effective when it is in contact with the surface of the product upon which the antimicrobial effect is desired. This suggests that chitosan should be on the inside surface of the package. In this work, a ma…
The organisation of identification of a technical condition of the power transformer with application of methods of artificial neural networks is considered.
在 sintering 过程和在 ZnO-Bi2O3-based 变阻器陶艺的 Bi2O3 的蒸发之间的关系被调查。阶段和微观结构进化在 sintering 过程期间被检验。结果证明更高 sintering 温度或 sintering 时间越长， Bi2O3 越被挥发。加热的率在 Bi2O3 上有小效果在 ZnO-Bi2O3-based 变阻器陶艺挥发了。这根据相对 X 光检查衍射山峰区域比率分析。结果也证明 sintering 温度在 Bi2O3 的蒸发上有最大的影响，然后到加热的率的 sintering 时间，和效果列在后面是最小。
The NCRP Wound Model describing the retention of selected radionuclides at the site of a contaminated wound and their uptake into the transfer compartment has been combined with the ICRP element-specific systemic models for those radionuclides to derive dose coefficients for intakes via contaminated wounds. Those coef…
研究了酸性介质中EDTA对高钛渣与NaOH熔盐反应水洗产物中Fe3+的络合作用,考察了EDTA加入量、反应时间、pH值和温度对Ti4+和Fe3+溶出率的影响.结果表明,增加EDTA量、延长反应时间、减小pH值及升高温度,Fe3+溶出率增大.将反应后的固相在105℃下水解可制得球状锐钛型TiO2,平均粒径为100nm,纯度可达99.3%.
The method of computer modeling investigates the mechanism of destruction BCC lattice of silver at deformation of shift (lll) and the direction of unstable displacement of atoms in a crystal is determined at infringement of a dynamic condition of stability.

Tissue Engineering setzt die Prasenz von sich regenerierenden Zellen, biologisch degradierenden Matrizen und Bioreaktoren, die die zellulare Umwelt regulieren. Zellen und…
采用燃烧法合成Tb^3＋，Ce^3＋ 掺杂的CaAl12O19发光粉，样品经紫外光激发后发明亮的黄绿光。使用X射线衍射仪、扫描电镜对所合成样品进行物相和显微结构分析。结果表明：所合成的发光粉晶相为CaAl12O19，合成物由微米级微小晶粒构成，随着燃烧引发温度的升高，样品的结晶程度相应提高，晶粒尺寸增大。荧光分光光度计测定了所合成样品的激发光谱和发射光谱，其激发峰和发射峰显示CaAl12O19：Tb^3＋，Ce^3＋ 的发光主要是由Tb^3＋的4f组态电子的^5D4→^7FJ跃迁产生，Ce针将吸收的能量传递给了Tb^3＋而起敏化剂作用。
Amino-functionalized MWNTs (MWNT-NH2), which were functionalized via a series of chemical modification using thionyl chloride and hexamethylene diamine, were adopted in fabrication of MWNT-NH2/PMMA nanocomposites. MWNT-NH2 reacted with PMMA by an aid of amino groups to form MWNT-NH2 /PMMA nanocomposites. SEM and TEM i…
Selective catalytic reduction (SCR) is a prospective way to reduce NO_x emissions from combustion devices.

Nous avons etudie une electrode d’acier au contact de silice et d’argiles dans deux situations tres differentes : le mineral est depose sur l’electrode en donnant un comportement relativement desaere ou il est en suspension dans un systeme mixte electrode tournante/convection forcee. Ces deux situations montrent que l…
