This volume presents the majority of topics in synchrotron science that are of use to the clay science community. The chapters presented in this volume serve not only as significant statements on the state of these applications, but also as useful primers to potential new users of synchrotron facilities.
Kitosan merupakan polimer yang ideal untuk formulasi nanopartikel, namun memiliki kelemahan yaitu karakter fisikokimia yang tidak konsisten serta bobot molekul yang relatif tinggi sehingga sukar larut. Radiasi sinar Gamma diaplikasikan untuk standarisasi sifat fisikokimia kitosan tersebut karena dapat memotong rantai…
MECHANICAL AND WEAR PROPERTIES OF ALUMINIUM COATING PREPARED BY COLD SPRAYING , Yusof SNA1*, Manap A1† Afandi NF1, Salim MA1, Misran H1, Nooririnah O2 1 Department of Mechanical Engineering, Universiti Tenaga Nasional, Jalan IKRAM-UNITEN, 43000 Kajang, Selangor, Malaysia. 2Faculty of Engineering Technology, Universiti…
Local damage measured on different scale levels in the process of carbon steel’s cyclic creep is studied. This damage is considered to be the result of accumulation of pseudo-random local residual deformations in polycrystal (within grains and more). An original statistical approach for estimation of global damage rev…
Vid Glafsfjordens strand nara Glava i Varmland ligger Hillringsbergs herrgard. I anslutning till den ligger en damm och en nedlagd kraftstation vars gamla turbinbyggnad star oanvand.Glava Energy Ce ...
Polymer nanocomposite is a new choice to conventionally filled polymers. Because of the nanometer sizes of filler, filler dispersion in this nanocomposite demonstrates markedly enhanced properties compared to pure polymers include an increased in their modulus and strength, thermal and mechanical properties. In this s…
V diplomskem delu je predstavljeno nacrtovanje, konstruiranje in izdelava naprave za mesanje koktajlov. Opisana je konstrukcija naprave, njeno delovanje in sestavni deli, med katere je vkljucen tudi pogon. Naprava je nacrtovana z uporabo nestandardnih strojnih elementov, ti pa s pomocjo programskega paketa CATIA. Sled…
Dibutil Ftalat (C16H22O4) mempunyai peranan penting dalam industri polimer sebagai plsiticizer, yaitu suatu bahan yang membuat polimer lebih mudah diproses atau dibentuk (plastis). Untuk memenuhi kebutuhan dalam negeri yang masih harus diimpor dari luar negeri dan adanya peluang ekspor yang masih terbuka, maka diranca…
The possible complex components of the states of crystal fractal nano-dimensional class for deterministic modular structures of composites were discussed.
Photoinduced isomerization of 1,1′-bis-indanyliden (stiff-stilbene) in solution was studied with broadband transient absorption and femtosecond Raman spectroscopies, and by quantum-chemical calculations. Trans-to-cis S₁ isomerization proceeds over a 600 and 400 cm–¹ barrier in n-hexane and acetonitrile, respectively.…

The IRC was created to encourage scientific research by undergraduate students and to help them better understand the exciting educational and research opportunities that exist in science and engineering.An appreciation for laboratory research is central to a working understanding of experimental sciences.By participa…
Die gitter- und spindynamischen Eigenschaften verschiedener Materialien mit fehlender Inversionsymmetrie in ihrer Struktur wurden mittels Neutronenstreuung untersucht. Die experimentelle Untersuchung der Gitterdynamik in FeSi, CePt(3)Si und SrPt(3)P wurde durch ausführliche Modellrechnungen im Rahmen der Dichtefunktio…
Wood fibres have several advantages compared to man-made synthetic fibres: they have high specific stiffness, are renewable, relatively inexpensive, available in industrial quantities and biodegradable. However, to increase and diversify their utilisation, it is necessary to increase the understanding on what controls…
To regulate and control the degradate rate and bioactivity of pure magnesium micro-arc oxidation bio-coating,the pure magnesium micro-arc oxidation film was treated by using Na2SiO3and HF-Na2SiO3,respectively,and detected by using a scanning electron microscope(SEM),X-ray diffraction(XRD),coating adhesion automatic sc…
NMR Spektroskopie ist eine oft vewendete Methode, um Strukturen von Molekuelen und Festkoerpern zu untersuchen und zu bestimmen. In dieser Masterarbeit wird der Fokus auf Festkoerper-NMR Spektroskopie gelegt. Die Resultate der experimentellen chemischen Verschiebungen mit den theoretisch berechneten chemischen Abschir…
In this project, ionic liquid 1-ethyl-3-methylimidazolium acetate (EMIMAc) was used in the spinning of regenerated cellulose micron fiber. EMIMAc is a better candidate for dissolving cellulose for the production of regenerated cellulose fiber because it has a lower melting point than 1-Butyl-3-methylimidazolium Chlori…
目的：制备聚L-乳酸（PLLA）复合纳米羟基磷灰石（n-HA）的新型人工骨材料,并对复合材料的性能进行研究。方法：采用熔融共混法,将PLLA与不同配比的n-HA进行复合,制备得到新型复合材料,并进行力学性能测试、显微结构观察,体外降解试验等项目的研究。结果：当掺入n-HA粉末含量为20%时,PLLA/n-HA复合材料的抗弯强度可以增加到最大值,材料断口的形貌随着n-HA含量的增加表现为不同的脆性断裂特征,复合材料降解液的pH值和力学强度的降低时间较纯PLLA滞后,降解速度减缓。结论：PLLA/n-HA复合材料可明显提高单一材料的力学性能,并可减轻降解过程中酸性产物引起的炎症反应,保持较好的初始力学强度,有望成为一种理想的骨缺损修复…
The corrosion of 13Cr tubing in a gas well was investigated and roundly inspected,and the tubing corrosion distribution status and corrosion concentration position of the tubing were obtained.It is considered that the tubing corrosion was due to CO2,Cl-and water.Some measures for preventing tubing from corrosion were…
Nanoparticle research is, at the moment, one of the most studied branches of science and is emerging as one of the fastest growing areas which includes different fields such as biology, medicine, optics, electronics or pharmaceutical technology, among others. In the last few years, it has emerged as a strategy, in pha…
