Light-induced plating (LIP), in which the current driving the metal reduction process is derived from illuminated solar cells, is an attractive technique for solar cell metallization because of its potential simplicity. However, applying the LIP techniques on standard acidic-textured multicrystalline silicon wafers wi…
이산화탄소와 에폭사이드를 단량체로 이용하여 친환경, 생분해성 지방족 폴리카보네이트를 합성하는 기술 은 최근의 이산화탄소 활용 기술의 하나로 많은 연구가 진행되고 있다. 본 논문에서는 이산화탄소/에폭사이드 공중합 에 이용되는 균일계 촉매의 개발 동향을 살펴보았다. 초기의 salen-Cr 화합물에서부터 이핵 아연 촉매계, 그리고 아민 염을 리간드로 갖는 다양한 salene-코발트계 촉매까지 이들의 구조와 촉매활성과의 연관성을 중심으로 기술하였다.
Soil algae of the background and recreationally disturbed soils of the birch phytocenoses in Novosibirsk region is researched in the article in the comparative plan. The changes concerning taxonomic organization of the soil algae as a result of recreational influence are revealed.
Materiais zeolíticos foram sintetizados utilizando como fonte principal de silício e alumínio um rejeito industrial gerado durante o beneficiamento do caulim para cobertura de papel; o material de partida e as fases formadas como produtos de reação foram caracterizados por difração de raios X, microscopia eletrônica d…
This paper deals with the mineralogical investigation of mafic enclaves, which are present in metamorphic calc-silicate rocks from the area of Novo Selo-Kriva Lakavica (Macedonia). The host calc-silicate rocks are situated in the Vardar zone, which occupies the central part of the Republic of Macedonia. The rocks in t…

The kinetics of the reduction of silver amine complexes in aqueous solutions were investigated and found to be second order overall, the rate being proportional to silver complex and hydrogen concentrations. These systems were studied under conditions of essentially complete complexing and therefore the rates were ind…
The effect of reprocessing High Impact Polystyrene (HIPS) has been studied in this paper. To simulate recycled HIPS, we reprocessed virgin HIPS through 5 cycles. The HIPS has been rheologically characterized after the various cycles of reprocessing in order to evaluate their corresponding properties and correlate them…
-RO/30 vol%SUS.Sintered porous samples were obtained which consists of well-distributed stainless steel particles within the glass matrix.Such a microstructure is desired for the purpose as a soot particulate filters（DPF）utilizing microwave rapid heating in cold start phase.Heating ability of the fabricated porous com…
patiently guided me through the whole Ph.D. program and taught me a lot of valuable research skills from his own academic experiences
Previous work had shown that near the composition MneoA1₂oC₂o there occurs a highly ordered cubic phase with interesting magnetic properties. A study of the effect of additions of iron and chromium has been carried out with a view to obtaining some information about the structure and magnetic properties. Two alloy gro…
To develop devices based on conducting polymers for the benefit of humanity - such as, for example, artificial muscles and lab-on-a-chip diagnostics - we require the ability to reliably fabricate and understand these materials at the micro and nano scales. In this thesis I present research towards that goal, by develo…
Dans les dernières décennies, les nanomatériaux hybrides organiques-inorganiques sont en plein essor. Ce sont des combinaisons de deux ou plusieurs composants qui génèrent de nouveaux matériaux aux propriétés nombreuses et variées. Les nanoparticules métalliques nobles les plus stables sont les nanoparticules d'or. El…
A series of some novel hybrid materials prepared via sol-gel process has been synthesized from various side chain coupler as precursors and heterocyclic 1,3,4-thiadiazole azo dyes. The start material 1,3,4-thiadiazole was synthesized from formic acid and thiosemicarbazide in reflux to get the 2-amino-1,3,4-thiadiazole…
Nowadays, ceramics and resin epoxy have been used in many sectors. In electrical engineering, ceramics and resin epoxy can be used for insulation. In order to used optimizely, dielectrics and physics characteristic of these materials must be stable although it has experienced aging. To know the characteristics of thes…
We have studied the effect of diffusion on the dynamics of desorption on a lattice-gas model The chemical potential during the adsorption phase was varied in order to vary the initial size distribution for the desorption phase. The effect of diffusion on the size distribution dynamics during the desorption process was…
Using six kinds of epoxy acrylates and a conductive carbon black, photosensitive resistor pastes were fabricated and then their developability in alkaline aqueous solution and the resistance values after thermal curing were evaluated. In order to impart the photocurability by UV exposure and the developability on alka…
The frame frequency of 240 Hz has been demonstrated for the Field Sequential Color (FSC) based on Electrically Suppressed Helix Ferroelectric (ESHFLC) E-0 mode. The proposed display, at the electric field of 3.33V/μm, is characterized by the high contrast (10000:1), wide viewing angle and large color triangle (130% of…
The main energy supply is shifting from oil-based to more natural gas-based since the depletion of crude oil reserves. The non-oxidative direct methane aromatisation over zeolite supported molybdenum bifunctional catalysts produces benzene, toluene, and xylenes as desired products, and hydrogen as a valuable by-produc…
