Silver nanowires exhibit high electrical and thermal conductivity. From the view of this point, silver nanowires are one of the most suitable nanowire materials. For synthesis of controllable silver nanowires, the effects of ions (NaCl and KBr) and polyvinylpyrrolidone (PVP) molecular weight were investigated. Silver…

Because the Pb-based piezoelectric materials showed problems such as an environmentalpollution. lead-free ZnSnO3 materials were studied in the present study. The ZnSnO3 thin films weredeposited at 640℃ on Pt/Ti/SiO2 substrate by pulsed laser deposition (PLD) and were annealed for 5 minat 750℃ using rapid thermal annea…

Fur die Aufklarung der absoluten Stereostruktur von chiralen Molekulen, die ein Chromophorsystem besitzen, hat sich die Kombination der experimentellen und theoretischen Spektroskopie des elektronischen Circulardichroismus (ECD) als Methode bewahrt. In der vorliegenden Arbeit wurden die chiroptischen Eigenschaften von…
Fabric structure is considered to be one of the major factors for the designer, to obtain the desired fabric properties; whether Mechanical or Natural. In fact, these properties play an essential role in determining Quality Standard, and its suitability to the Job Performance Fabric Properties have currently become of…

çalışmada dört yeni iminooksim ligandı, fenil-(1-fenil-etilimino)etanal oksim (ffeieoH), (2-hidroksi-etilimino)-2-fenil-etanal oksim (heifeoH), 2-(hidroksiimino)-1-feniletiliden]asetohidrazon (hifeahH2), (2-hidroksi-etilimino)-naftalin-2-il-etanal oksim (heineoH) ve bu dört ligandın palladyum(II) ve platin(II) iyonlar…
Ligth-induced changes in the optical properties of Ge-Te-In thin films have been studied. The refractive index, the absorption coefficient and the optical band gap of the films have been determined before and after exposure by analyzing the material's transmission spectrum. The thin film's nonuniform thickness was acc…
La adsorcion con intercambiadores de tipo compuesto esta incrementando su aplicacion en el tratamiento de residuos liquidos radioactivos por su mayor estabilidad frente a la radiacion y su mayor selectividad frente a determinados radionucleidos. El objetivo de este trabajo es la sintesis de un material adsorbente basa…
수중 음이온계 고분자 물질과 콜로이드의 상호작용은 입자 안정화, 혹은 반대로 응집에 영향을 미친다. 예를 들어, 휴믹물질의 경우 입자 안정화하고 PAM의 경우 입자 응집을 도모한다. Stericrepulsion 작용하에는 입자표면의 고분자물질이 입자 반발력을 증대시켜 안정화 한다. Chargeneutralization 에서는 고분자물질이 입자표면의 정전기력을 중화시키므로 응집을 증대시킨다. Bridging mechanism 작용하에는 고분자물질이 입자를 서로 엉겨붙게 만들어 응집을 증대시킨다. 이와 같은 고분자 물질의 입자 응집 및 안정화 작용에는 다양한 물리화학적…
