Cement production is an energy-intensive process, whic h has traditionally been dependent on fossil fuels. However, the usage of selected waste, biomass, and by-products with recoverable calorific value, defined as alternative fuels, is increasing and their combustion is mo re challenging compared to fossil fuels, due…

HgTe nanoparticle were conveniently prepared via solvothermal decomposition of novel single source molecular precursor(SSMP), i.e. mercury (ii) complex of bis(isopropyltelluro) propane. Synthesized nanomaterials were well characterized by powder XRD, SEM, TEM. Surface morphology of synthesized nanomaterials was studie…
This abstract performs experimental investigations on the jumps of rotation and temperature in non-linear torsional vibration of NiTi wire. With a synchronized measurement of rotational angle and temperature, the jumps of mechanical and thermal responses are captured simultaneously near the eigenfrequency. It’s shown…
Validation of the individual steps of the processes is called the process validation. In this study the process validation was carried out for the tablet dosage form which contains Clopidogrel bisulphate 75 mg. In tablet dosage form, critical parameters like dry mixing, drying, lubrication and compression were taken u…
Forsterite (Mg 2SiO 4) powder was synthesized by using magnesium and talc with assistance of ball milling and subsequent heat treatment. Manganese doped forsterite was prepared at weight percentage of 0.05%,0.1%,0.2%,0.5% and 1.0wt% by adding manganese oxide before ball milling. The undoped and manganese doped forster…
Process conditions of furfural produced from bamboo by a 2-step method at atmospheric pressure were studied. The first hydrolysis step of bamboo hemicellulose was researched by the experimental factors such as liquid-solid ratio, reaction time, and volume fraction of organic solvent, volume fraction of sulfuric acid a…
The objective of this thesis has been to investigate alternative catalysts and technologies which are able to handle the challenging o-gases from biomass- and waste-red units. Nitrogen oxides are unwanted by-products formed to some extent during almost any combustion. These by-products are usually removed with the sel…
Enhancement of polymer electrolyte fuel cell tolerance to CO impurities would allow the use of lower quality hydrogen, thus reducing the costs without compromising fuel cell performance. In this work, the effect of carbon monoxide is mitigated by combining different methods, including air bleed, varying the anode flow…
The formation constant of mixed ligand complexes of zinc (II) with Schiff bases (1-(2-hydroxy benzamido)-2-(fur-2- yl)-azomethine) L1, (1-2-hydroxyhexamido)-2-(thien-2-yl)-azomethine) L2 as primary ligands and Glycine (R1) , DLValine (R2) as secondary ligands have been determined potentiometrically in 40% (v/v) THF-wa…
Correns’ and Steinborn’s pioneering experiment is probably the most intriguing one in the field of salt crystallization. It consisted of the measurement of the force needed to prevent a monocrystal of potassium alum (potassium and aluminium sulfate dodecahydrate, KAl(SO4)2∙12 H2O) from growing in various supersaturate…
Experiments were conducted to investigate deformation-induced processes during in-situ tensile test at elevated temperature. Consequently the microstructure after creep loading was examined by 3D Electron Back Scatter Diffraction (EBSD) technique. The billets of coarse-grained copper were processed by equal-channel an…
Storage of spent nuclear fuel and high-level waste in dual purpose casks (DPC) is related with the challenge of maintaining safety for transportation over several decades of storage. Beside consideration of mechanisms by appropriate design, material selection and operational controls to assure technical reliability by…
N,N-dimethylaminobenzylideneamino) phenyltellurium tribromide synthesed by reaction of ehtanolic solutons of 4- aminophenylmercuric chloride with 4-N,N-dimethylaminobenzaldehyde then with tellurium tetrabromide. The prepared compund 4-(4-N,N-dimethylaminobenzylideneamino)phenyltellurium tribromide was charecterized by…
Nanocatalysis is a very active field, so there are a few studies in the shape dependent catalytic properties of transition metals from a thermodynamics approach. Transition metal nanoparticles are very attractive due to their high surface to volume ratio. Bimetallic nanoparticles are the combination of two metals of t…
Polyhydroxyalkanoates (PHA), a class of microbial polyesters produced from fermentation, is of interest for scientists and environmentalists due to its wide-ranged combinations of monomers, biodegradability and biocompatibility properties. In this study, efforts were made to understand the kinetics of isothermal cryst…
Beam losses may cause activation of vacuum chamber walls, in particular those of the Large Hadron Collider (LHC) experiments. For the High Luminosity LHC, the activation of such vacuum chambers will increase. It is therefore necessary to use a vacuum chamber material which interacts less with the circulating beam. Whi…
This project report presents design, simulation and development of passive shunt filter and shunt hybrid power filter (SHPF) for mitigation of the power quality problem at ac mains in ac-dc power supply feeding to a nonlinear load. The power filter is consisting of a shunt passive filter connected in series with an ac…
Background: The use of thermoplastic material is increasing in all industries and human daily lives especially polypropylene (PP) and polyethylene (PE). Additional of PP into PE could impart extra mechanical strength of the final products. This study analysed the mechanical strength and structural changes of different…
アクリル酸を5 wt%含むアクリル酸−n-ブチル−アクリル酸ランダム共重合体（A）およびアクリル酸２エチルへキシル−アクリル酸ランダム共重合体（B）の架橋剤量を変化させたモデル粘着剤を用いたプローブタック試験で，タックの接触時間にともなう上昇率におよぼす粘着剤の分子構造の影響を検討した。接触時間は1~30,000秒の範囲で，プローブはステンレススチール（SS）製である。タックの上昇率はB>Aで，共に架橋剤濃度にともなって低下した。また，タックは接触時間約100秒ではA>B，これ以上ではB>Aであった。パルス各自帰郷名宝測定より，分子運動性がB>Aであったことから，被着体表面への濡れ性はB>Aで，接触時間が長くなるほどこれが顕著にな…
