Podlaga za izdelavo magistrskega dela je povprasevanje enote Ulitki v podjetju Talum d.d. po novem orodju za litje aluminijevih zlitin. Narocnik projekta (nemsko podjetje Bosch) je zasnoval nov izmenjevalec toplote imenovan C6 future, ki ga je bilo potrebno preuciti, iz prejetega modela ulitka izdelati model jedra ter…
Different environmental samples reveal that methanogenic Archaea are part of a multi-species biofilm on corroding metallic structures (Fig. 1). Studies on microbial influenced corrosion (MIC) focus mainly on sulphate reducing Bacteria (SRB), leading to the assumption that they are exclusively responsible for metal cor…
本研究ではX線光電子分光法（XPS）を用いてLa1-xSrxMnO3の電子構造解析よりその導電性を評価した．まず，硬X線光電子分光法でのみ観測可能であると報告されていたMn 2p3/2スペクトルにおける低束縛エネルギー側の肩構造（Mn3+の遮蔽された終状態）が，実験室XPSでも観測されたことを報告する．次に，Mn3+，Mn4+，及びこの肩構造を多ピークフィッティングにより分離し，Sr置換量xで決まるMn3+ ⁄ Mn4+比を考慮した結果，上記以外の強度が存在することがわかった．このピークはMn4+の遮蔽された終状態に由来すると考えられ，Mn3+及びMn4+の遮蔽された終状態のピーク強度の総和をxに対してプロットすると，LSMOの導…
Polythiophene-Polyethylene oxide (PTh-PEO) polymer composite was synthesized using Ferric Chloride (FeCl3) as oxidant by in situ chemical oxidative polymerization method. The polymerization was carried out at room temperature. Attempts were made to increase the electrical conductivity by using various concentration of…
The problem of the balance of the rectangular thin plate with two adjacent edges fixed the other two adjacent edges free under the uniform load is solved by using the minimum potential energy of mixed variables. The solution process is clear, and the deflection surface equation is given. Through the numerical calculat…

Superhydrophobic surfaces have drawn a lot of interest both in academia and in industry because of the usability and their wide applications.Inspired by the extreme wetting states displayed by the natural materials, superhydrophobic surfaces have been widely fabricated by various techniques.In this work, superhydropho…
ZnO films doped with Nd contents of 0%-0.81% were deposited by a chemical solution deposition and characterised by X-ray diffraction, field emission scanning electron microscopy, UV-vis and luminescent spectrophotometry and electrical measurement. The experiments revealed that the films have nano-scale particle size t…
A refined higher-order zig-zag model in conjunction with a new modified couple stress theory capable of capturing scale effect is proposed for vibration analysis of composite microbeams. The aim is mainly focused on the effects of transverse shear stresses on the accurate prediction of natural frequencies for composit…
钙镁质磷矿石中白云石因其较高的溶解性导致矿浆中含有大量Ca2＋、Mg2＋影响浮选指标。通过测定溶出离子浓度,研究了pH对白云石表面离子溶出行为的影响。考察了酸性条件下白云石表面溶出液及添加Ca2＋、Mg2＋对其可浮性、Zeta电位和捕收剂吸附量的影响。结果表明：酸性条件下白云石表面Ca2＋、Mg2＋溶出速率快,符合二级动力学方程;自然pH及碱性条件下溶出相对缓慢,符合一级动力学方程。白云石表面溶出Ca2＋、Mg2＋抑制其浮选,与人工添加Ca2＋、Mg2＋浮选效果相同。Ca2＋、Mg2＋对白云石表面Zeta电位无明显影响,但使捕收剂在白云石表面吸附量减小,可浮性下降。
In this thesis the behaviour of iron-containing and -free amorphous soot under UV- and X-ray irradiation in the range from 6 eV to 500 eV was investigated. The interstellar extinction bump at 217nm has been known for more than fifty years, but its carrier is still unknown. Current research supports the idea that this…

Water aerosols affect the climate because they have an impact on the radiation balance and cloud formation. Water is present in all forms in the atmosphere (water, ice and steam), for example as rain and hail. Water aerosols play an important role in many biological and chemical processes in the atmosphere. The most c…
The IEEE International Magnetics Conference, Intermag Europe 2017, was held in Dublin, Ireland, from April 24–28, 2017. There were 1470 registrants from over 50 countries (including 45% from Europe, 37% from Asia, and 10% from the USA). A total of 2060 contributed digests were submitted, 73% of which were accepted, to…
Parameter identification of GISSMO damage model for DOCOL 900M high strength steel alloy : Usage of a general damage model coupled with material modeling in LS-DYNA for Advanced high strength steel crashworthiness simulations
Soil-water interaction is important to understand various soil behaviors. However, the theoretical understanding of soil-water interaction mechanisms is still incomplete especially in the adsorptive regime of soil water retention curves. Molecular simulation techniques were introduced herein to fill historical knowled…
汎用高分子としてPMMAを用い，p型，n型それぞれのナノファイバーコンポジットフィルムを接合した相補型デバイス(有機pn接合ダイオード)を作製し，温度依存性を評価した．作製した有機pn接合ダイオードは整流性を確認することができたが，温度の低下にともなって，電流値が小さくなり，理想係数が増加する傾向がみられた．また，作製したpn接合ダイオードの逆飽和電流の温度依存性より求めたエネルギーバンドギャップは，負の電圧領域におけるリーク電流の影響と，n型のキャリア不足を補うための大量のドーピングによる，不純物準位の影響を受け，非常に小さい値となった．フレキシブル基板を用いた場合でも，この有機pn接合構造は整流性を発現したが，曲げた状態では整…

Analysis of noncovalent sorption and desorption of complex samples is costly and time con- suming. Efficiency of this analysis has been increased through the novel discontinuous vacuum extraction by equilibrium headspace gas chromatography technique (DVE-HSGC) that has been developed. This research quantified the simu…
