It has been a while since Edwards and Anderson started investigating spin glasses through introducing random bonds in the Ising Model in 1975. The resulting Random Bond Ising Model (RBIM) has since been the focus point of much study, but it is still far from being fully understood. For my thesis, I investigated the dy…
Biosynthesis of metal nanoparticles using microbes, plants and plant extracts provides a viable alternative green approach for nanoparticle synthesis in comparison to conventional chemical approaches. The use of biosynthesis offers significant advantages over chemical synthesis in context of reduction of energy consum…

Abstract The magnetic Ni0.3 Zn0.7 Fe2 O4 nanoparticles were expected to have wide applications in bionanoscience and electronic devices technology. In this work, Ni0.3 Zn0.7 Fe2 O4 nanoparticles were synthesized successfully by a redox chemical reaction in an aqueous solution of nickel chloride, zinc chloride and ferr…

We report tunnel experiments on Bi2Sr2Ca1-xYxCu2O8+δ(Y-Bi2212) crystals with x=0, 0.01, 0.05, 0.1, 0.11, and 0.12. The results are discussed about Cooper pairs existing. Tunneling spectra were measured for Y-Bi2212 crystal-SiO-Ag planar junctions. For superconducting samples the V-shaped gap structure and zero bias co…
Magnesium merupakan unsur menjanjikan sebagai material hidrogen storage. Salah satu contoh paduan yang selama ini banyak dikembangkan sebagai metal hydride ialah paduan MgAl karena penambahan Aluminium pada Magnesium dapat mengikat hidrogen sebanyak 3,02% wt. Dalam penelitian ini, metode yang digunakan ialah mechanica…
Pythium ultimum is an oomycete which causes serious economic losses in greenhouses by causing damping off disease. Ascophyllum nodosum is known to act as a nutrient supplement and its application has shown to reduce diseases caused by microbial pathogens in plants. However, its byproduct, one that is left after the ex…
Kutatómunkám során a kitozán és a poli-gamma-glutaminsav önrendeződésével olyan stabilis nanohordozót állítottunk elő, amely 100-120 nm hidrodinamikai méretű és felületi töltése negatív, valamint képes paramágneses Gd(III)-ionok, illetve szuperparamágneses SPION részecskék szállítására. A nanohordozót alkotó biopolime…
Özet Bu çalışmada, elektromanyetik yöntemle malzeme karakterizasyonu için kullanılan yay (arch) ölçüm sisteminin 8-12 GHz frekans bandındaki ölçüm kabiliyetleri sunulmaktadır. MİLTAL laboratuvarı bünyesinde kurulmuş olan yay sisteminde, elektromanyetik dalganın polarizasyonuna ve geliş açısına bağlı malzemenin yansıma…
A descricao microestrutural de acos e feita frequentemente por meio das tecnicas de microscopia optica e eletronica de varredura, que permitem identificar as principais fases e constituintes presentes. A complexidade microestrutural dos constituintes formados em maiores taxas de resfriamento, durante o resfriamento co…
Pós obtidos de polpa de goiaba (Psidium guajava L.) liofilizada, elaborados com adição de sacarose, em concentrações variando de 0% a 20% e pectina, em concentrações de 0% a 1%, foram desenvolvidos neste trabalho. A estabilidade de tais pós foi avaliada com relação ao comportamento higroscópico durante o armazenamento…
Hydrogenases are a group of enzymes that catalyze the reversible cleavage of molecular hydrogen and are present within aerobic and anaerobic bacteria, archaea, and eukarya. The third class of hydrogenase (which can be obtained from methanogenic archaea grown in nickel-limiting and red light conditions) was originally…
The Inside Cover picture shows the plasmonically enhanced thin dye-sensitized solar cells developed by Kang et al. through synergistic near-field and far-field coupling of size-controlled plasmonic nanoparticles. Molecular complex dyes absorb photons with roughly 100 times lower adsorption intensities than those of ot…
The dynamic response after pump switch-on of a 980 nm pumped-ring laser based on an active photonic crystal fiber with an Er3+ ion concentration of ≈1020 ions cm−3 was registered. Then a numerical fitting procedure of a theoretical model was followed to the experimental values of the relaxation oscillation parameters…
An appearance of the photoluminescence anisotropy induced by photochemical reaction under continuous irradiation with polarized light is demonstrated for an ensemble of CdSe/ZnS quantum rods chaotically embedded in the pores of filter paper. A specific relaxation of the photoinduced anisotropy is revealed in darkness…
One important key to improve the bulk-heterojunction photovoltaics (BHJs) is the fill-factor (FF). In this work, a study of the FF dependence factors on BHJs with an active layer of MEH-PPV / PCBM is made. The FF changes from 20% to 70%, depending on the current – voltage behavior and on the photovoltaic equivalent ci…
ABSTRACT This work we presents a detailed result of Organic Light Emitting Diodes based on europium complex as emitting layer, the tris (dibenzoylmethane) mono (4,7-dimethylphenantroline) europium (III) Eu(DBM) 3 phen. The electrical d.c. and a.c. behavior is analyzed and correlated with the electroluminescence da…
In this paper, the effect of uniaxial deformation of PP/organoclay composite fibers in spinning and drawing on their supermolecular structure, thermal and mechanical properties is presented. The commercial organoclays Cloisite C15A and Cloisite C30B, both based on montmorillonite (MMT) were used in experimental work a…
The main distinguishing feature of the fiber is simply that it is a particle where the ratio of length to width ratio is very large. This provides connectivity between two relatively remote areas. Such linkage may confer strength through physical linkage or may relate primarily to information transfer. In the inorgani…
