Prikazani su ostvareni ciljevi na projektu.
Dye sensitized solar cells (DSC’s) have received considerable attention once this technology offers economic and environmental advantages over conventional photovoltaic (PV) devices. A DSC photoanode typically consists of a nanocrystalline porous TiO2 film, endowed with a large adsorptive surface area. Dye molecules t…

For the design of drug delivery systems, in which a large amount of drug should be stored and released over a sustained period of time, utilization of nanostructures is frequently advantageous as their high specific surface areas are beneficial for adsorptive drug loading. Additionally, the use of nanostructured drug…
I en inledande fas av projektet undersoktes allmant forutsattningarna att anvanda en smaltextraktionsapparat for matningar av diffusibelt vate. Tva konkreta fragestallningar framkom ur detta. Reste ...

The article considers the principles of defining the direction to the acoustic radiation source. The results of the research in the field of directing properties of the registrating devices when operating these beams are cited.
The results of analyzing the deformation process along "fan-type" two-part broken trajectories (tension with twisting), using the flow theory with translational-isotropic hardening, are presented. The results of the theoretical analyses are compared with experimental ones. Qualitative and applicable for engineering an…
본 연구에서는 Bi0.5(Na0.82K0.18)0.5TiO3 (BNKT) 세라믹스의 소결거동, 유전 및 압전 특성에 대한 과잉의 CuO 첨가 효과를 살펴보았다. 과잉의 CuO를 소량 첨가하면 소결 과정에서 치밀화와 입자 성장에 크게 도움을 주지만, 3 mol% 이상 첨가하면 소결 후에 입계에 CuO가 석출이 되는 문제가 발생하였다. 1∼2 mol% CuO를 첨가하여 975℃의 낮은 온도에서 소결한 시료가 소결조제를 넣지 않고 1,175℃에서 소결한 시료에 필적하는 압전 특성을 나타내어서, CuO를 소결조제로 이용하면 저온소성을 통한 BNKT 적층형 세라믹 액추에이터…
This paper describes an inverted bulk heterojunction organic solar cell featuring solution-processed zinc oxide nanoparticles (ZnO NPs) as the electron transport layer. ZnO NPs with an average diameter of ~5 nm are synthesized by a wet chemistry method. The ZnO NP layers are deposited from colloidal ZnO NPs dispersed…
Solar cells are promising alternatives to fossil fuels as they provide a clean source of renewable energy. Organic bulk heterojunction solar cells based on semiconducting polymers have potential as a low cost alternative to silicon solar cells due to reduced material costs, mechanical robustness and simple fabrication…
A new method of optical studies of microdefects under uniaxial compression of transparent specimens is proposed. In the view of the microscope the evolution of the microstructure is traced up to major cracks initiation. The emergence of new and resizing of existing microdefects are revealed and analyzed. Keywords: uni…
近年来， 因2 μm波段激光在军事、医疗和遥感探测等方面有着广阔的应用前景引起了广泛的关注。作为2 μm激光器核心工作物质的激光材料也成为研究的热点。其中该波段光纤激光器用的激光玻璃和光纤已经成为该领域的一个重要研究方向。目前，在石英光纤、锗酸盐玻璃光纤、氟化物玻璃光纤和碲酸盐玻璃光纤基质中已经实现了2 μm激光输出。但是上述几种光纤分别存在稀土掺杂浓度低、成本高、机械强度差等缺点。与石英光纤相比，硅酸盐玻璃稀土掺杂浓度高，与其他多组分玻璃光纤比，硅酸盐玻璃光纤机械强度高，化学稳定性好，原料成本低。虽然国外已经有硅酸盐玻璃光纤2 μm激光的报道，但是国内仍属空白。 本论文以2 μm波段激光输出用掺铥硅酸盐玻璃与光纤作为研究对象，对…

In conclusion, phase field simulation method is employed to understand the relations between composition and interdiffusion microstructure as well as relations among composition, ferroelectric domain structure and piezoelectric property of ferroelectric MPB materials and helps answering some important questions both i…
Drug delivery to the lungs is difficult to achieve and conventional approaches like intravenous and oral administration of drugs do not effectively deliver drugs to the lungs. The inhalation route of administration provides a way to deliver the drugs locally, thereby increasing their efficacy. However, there are sever…
Les latrines a fosse simple sont l’une des plus vieilles formes d’assainissement ameliore dans le monde, et pour beaucoup, elles restent la meilleure option. Les latrines a fosse simple peuvent etre facilement construites en utilisant des materiaux et technologies locales. Comparees aux autres formes d’assainissement,…
