This report is meant to give a brief introduction to tool steels, phases and alloying elements. The focus is to understand the microstructure, its evolution and how it is altered through processing ...
원자층 증착법을 이용한 SnO 2 , TiO 2 박막의 성장과 성장된 박막의 구조적 특성 및 수소 가스 감응 특성 연구 Growth of SnO 2 and TiO 2 thin films by PE-ALD : their structural characteristics and H 2 gas sensing properties 2014 년 8 월 서울대학교 대학원
In the light of the new paradigm provides a brief overview of the works, reflecting mainly the evolution of the dynamical theory of martensitic transformations applied to the selection rules of dislocation nucleation centers of martensitic crystals. It is noted that the inclusion of quasi-longitudinal waves alters the…
Der synthetische Klinopyroxen LiScGe2O6 wurde mittels in-situ Hochdruck Raman Spektroskopie und Röntgenbeugungsmethoden untersucht. Drei Strukturverfeinerungen bei 0.0001, 4.94 und 9.51 GPa wurden durchgeführt. Sie bestätigen die Raumgruppe P21/c; Die Gitterkonstanten sind bei 0.0001 GPa a = 9.9999(8) A, b = 9.1040(2)…
Tin oxide thin films of differentmolarities were successfully deposited by spray pyrolysis technique on preheated glass substrates at a temperature of 500°C. The Effect of molarity concentration on film properties was investigated. All deposited films were characterized by various techniques such as X-ray diffraction…
Cathodic protection in the sacrificialsystem is essentially a controlledelectrochemical cell; corrosion on theprotected structure is shifted to theanode. When the anode material iscoupled to steel, they behave anodicallyand discharge current.In this work,magnesium used as sacrificial anode forthe protection of carbon…
An effective structural codoping approach is proposed to modify the photoelectrochemical(PEC)properties of anatase TiO2by being doped with nonmetal(N or/and C)and transition metal(Re)elements.The electronic structures and formation energies of different doped systems are investigated using spin-polarized density funct…
Die Therapie mit Photosensitizern stellt eine nebenwirkungsarme Alternative zu den herkömmlichen Behandlungen von vielen Hauterkrankungen und oberflächlichen Tumoren dar. Jedoch ist die Anwendung wegen der für die praktische Handhabung nachteiligen Eigenschaften wie geringer Löslichkeit der Wirkstoffe limitiert. Um di…
Diese Master-Arbeit befasst sich mit der Untersuchung der optischen Eigenschaften von Bor-dotierten einwandigen Kohlenstoff-Nanoröhren (SWCNT). Bor ist, aufgrund der geringen Größenunterschiede zwischen Bor- und Kohlenstoffatomen, eine der natürlichen Dotierungssubstanzen für SWCNT. Dennoch gestaltete sich die Herstel…
During the construction of steel storage oil tanks, a state of stresses under wind loads is induced which is not covered by the regulations. Cases of collapse of such structures during their construction occurred in Patagonia Argentina and elsewhere under moderate wind speeds, as reported in the literature. Previous n…
Measurement of the dielectric properties of different substances has been the subject of many researchers and various models have been proposed to interpret the experimental results.Dielectricmeasurements on ionicmaterials give useful information about dynamic processes involving ionic motion. In this paper the dielec…

As an alternative energy generation device with higher efficiency compared to conventional devices, the solid oxide fuel cell (SOFC) has been widely investigated. However, the application of SOFC is seriously limited due to the difficulty of maintaining an effective balance between excellent performance and strong sta…
Experimental evidence for the possibility of controllably transforming the habit of copper microcrystals formed by electrodeposition has been presented. Selective evolution of microcrystal facets with a specific crystallographic orientation has been performed by a premeditated change in the chemical composition of a s…
An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space grou…
El zirconio fue bien reconocido como un biomaterial estético y resistente para la fabricación de implantes dentarios. La biocompatibilidad que presenta en relación a los tejidos subyacentes a las piezas dentarias, también arrojaron excelentes resultados. En estudios de investigación en los que se comparó la adhesión d…

Some results of computer simulation of atomic structure of amorphous metals (Al, Cu, Ni), received from melts by force of ultra-fast cooling are cited and analyzed from the position of dynamic systems theory. It is determined that the atomic structure of such amorphous metals is unpredictable and irreproducible. A hom…
Представлено діагноз і опис нової форми Peridinium gatunense Nygaard f. kinneretа Krachmalny f. nov. із оз. Кіннерет. Від типової форми вона відрізняється будовою і розташуванням апікальних пластин і швів між ними (1’ – асиметрична, велика, її верхня частина зміщена в ліву сторону тіла; 3’ – клиновидна, витягнута; 4’…
