Electronic, structural, vibrational and elastic properties of PaN have been studied both at ambient and high pressures, using first principles methods with several commonly used parameterizations of the exchange-correlation energy. The generalized gradient approximation (GGA) reproduces the ground state properties sat…
In this present work, cobalt-iron, cobalt-platinum, iron-platinum and cobalt-iron-platinum systems were synthesized and characterized. Pure Co film was electrodeposited on brass substrates from sulfate plating baths containing sodium saccharin. The compositions of the electrodeposits were found depended on the concent…
作为钠硫电池陶瓷电解质的核心材料, Na-β-Al2O3粉体对钠硫电池的性能影响很大。实验以聚乙烯吡咯烷酮（PVP）为络合剂, 合成了纳米 Na-β-Al2O3粉体。结果表明, 以 PVP 络合的前驱体形成 Na-β-Al2O3相的温度低至 900 ℃, 相比于传统固相合成法及其他化学合成法有显著的降低, 可有效抑制传统制备Na-β-Al2O3粉体方法中由于高温而导致 Na2O 组份的挥发, 从而避免 Na-β-Al2O3性能的下降。X射线衍射, 扫描电镜和透射电镜对粉体的分析表明, 所获得的粉体为纯相的 Na-β-Al2O3, 粉体粒径 60~70 nm, 分散性好。高分散性的纳米粉体有助于制备高致密度的 Na-β-Al2O3陶…
The project is to investigate structure, magnetism and spin dependent states of novel group IV element-based magnetic thin films and heterostructures as a function of composition and epitaxial constraints. The materials systems of interest are Si-compatible epitaxial films and heterostructures of Si/Ge-based magnetic…

Bentonite clays have long been used as additives in animal feed, aiming to improve pellet quality and prevent caking. Certain bentonites are also capable of deactivating aflatoxin B_(1) (AfB_(1)) in feed by adsorption, therefore, detoxifying the feed. However, a 10–fold difference in adsorption capacity has been obser…
Tento clanok je venovaný problematike optimalizacii prevadzky elektrizacných sustav (ES). Optimalizacia ES bola robena s cieľom minimalizovať cinne straty v uvažovanej sieti, ku ktorým dochadza pri prenose elektrickej energie. Za týmto ucelom bol použitý STATCOM (Statický synchronny kompenzator). Vsetky uvedene simula…
Katalis Ca1-xCuxF2 (x= 0; 0,025; 0,05; 0,075; 0,1 dan 0,15) dipreparasi dengan metode sol gel dan dikarakterisasi dengan difraksi sinar-X (XRD), adsorpsi gas nitrogen dan metode adsorpsi piridin FTIR. Kemampuan katalitik katalis diuji pada reaksi trimetilhidrokuinon (TMHQ) dan isofitol. Hasil menunjukkan bahwa semua k…
Tento prispevok sa zaobera meranim zmeny ucinnosti tienenia elektromagnetickeho poľa v zavislosti na case pri postupnom vysusani stavebneho materialu. Meraným objektom bol stavebný material, konkretne vlaknocementova fasadna doska Eterplan s hrubkou 8 mm, ktora sa použiva pre vonkajsie fasadne použitie pri zlepseni te…
The focus of the present research is the synthesis of polypeptides for the study of protein folding and misfolding and for the development of novel polypeptide-based optical antennas in nanotechnology. It is hypothesized that simple polypeptides can be used as models to mimic in vivo folding of globular proteins. Desi…
Quantum field-theory is developed for treating electrons and holes in planar systems. Non-unitary representations of Dirac equation in the plane are developed. These equations can be used for treating holes-electron pairing in high TC materials where in a non-relativistic approximation we have a relatively small energ…
Abstract Two series of terpoly(methoxy‐cyanurate‐thiocyanurate)s based on thiodiphenol and dithiodiphenyl sulfide and on dihydroxydiphenyl ether and dithiodiphenyl ether, were prepared in good yield and purity and fully characterized. Most of the resulting polymers, formed at room temperature using phase transfer cata…
Phase change materials have been widely used in optical and electronic storage due to rapid and reversible phase transition between amorphous and crystalline states with remarkable resistivity and optical contrasts. More recently these materials have been identified as suitable candidates for phase change random acces…
Das Große sehen: Eine neue Methode vereinfacht die Herstellung unsymmetrischer makromolekularer Komplexe, in denen nur ein Teil der Untereinheiten NMR-aktiv ist, was zu weniger komplexen Spektren führt. Für die heteroheptameren LSm1–7- und LSm2–8-Ringe wurden NMR-Spektren der einzelnen Untereinheiten im gesamten Kompl…
We describe a low-energy glow-discharge process using reactive ion etching system that enables non-circular device patterns, such as squares or hexagons, to be formed from a precursor array of uniform circular openings in polymethyl methacrylate, PMMA, defined by electron beam lithography. This technique is of a parti…
The reflection of light from a semiconductor structure on a silicon wafer is analyzed with the finite-difference time-domain technique, with the structure gradually modified for typical defect categories. The effect of these changes on the near and far fields of the reflected light is determined, including the behavio…
In this paper, we developed an intriguing ion-exchange reaction to synthesize Ni -doped titanate nanotubes ( Ni - Ti -NTs), and utilized the sample as an appealing pseudocapacitive electrode for electrochemical capacitors (ECs). The energy storage mechanism of the resulting Ni - Ti -NTs electrode in alkaline KOH aqueo…
Um material eletrocromico e aquele que possui a capacidade de alterar sua coloracao reversivelmente ao sofrer reacoes redox quando estimulado por uma corrente eletrica ou por uma diferenca de potencial adequada. Os materiais eletrocromicos podem ser classificados como oxidos de metais de transicao, materiais de interc…
