In this thesis, the potential of the electrospinning technique as a tool for the preparation of fuel cell electrodes was studied. In the first part of the work, electrospinning was used to prepare porous electrode structures that allow for rapid transport of both fuel and water as well as protons and electrons to and…
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease affecting the upper and lower motor neurons causing muscle atrophy and paralysis followed by death. Aggregates containing superoxide dismutase (SOD1) are found as pathological hallmark in diseased ALS patients. Consequently ALS is regarded as a protein…
Nanoporous gold (NPG) is conventionally made via dealloying methods1. We present an alternative method for bottom-up chemical synthesis of nanoporous gold film (cNPGF), with properties resembling those of dealloyed NPG. The developed procedure is simple and only benign chemicals are used. Chloroauric acid is reduced t…
Due to increasing threats from terrorism in the past decades, progressive collapse modeling of buildings is gaining popularity with objective of simulating collapse process of the whole or partial structural system, in order to give useful insight to improve existing design for the structure against progressive collap…
Выполнены исследования магнитных свойств кислород-дефицитного нанокристаллического недопированного диоксида титана, синтезированного газофазным, электровзрывным и химическим методами. Дефектное состояние контролировалось с помощью восстановительных обработок в вакууме или в среде водорода. Показано, что дефектное сост…
С использованием ab initio расчетов получены данные о структурных, электронных, оптических свойствах титаната висмута со структурой типа пирохлора и соединений с замещением атомами скандия, индия позиций висмута, титана. Результаты теоретических расчетов согласуются с экспериментально полученными структурными и оптиче…
Dysregulation of cellular metabolism is a key feature of major diseases such as diabetes and cancer. Monitoring cellular metabolic alterations is of critical importance for improved understanding of disease progression and the development of novel therapeutics. Carbon-13 magnetic resonance spectroscopy (13C MRS), whic…
Scalable and sustainable solar hydrogen production through photocatalytic water splitting requires highly active and stable earth-abundant co-catalysts to replace expensive and rare platinum. Here we employ density functional theory calculations to direct atomic-level exploration, design and fabrication of a MXene mat…
Trunnion wear とは，人工関節ステムのヘッドネック接合部のtrunnion に生じる摩耗や腐食のことである．メタルオンメタル人工股関節全置換術（MoM THA）におけるtrunnion wear によるadverse reaction of metaldebris（ARMD）の報告が散見される1,2）が，人工骨頭置換術ではtrunnion wear を生じたという報告はほとんどない．今回，AML‒plus ステム（DePuy 社，Warsaw）を用いた人工骨頭置換術後にtrunnion wear が疑われた症例を経験したので報告する．
The paper describes a convenient and facile methodology for the synthesis of 2,5-diphenylthiophene derivatives.The environmentally friendly synthetic approach is supported by a one-pot tandem reaction process.All of the target products was confirmed by 1 H NMR, 13 C NMR and HRMS.On this basis, UV and fluorescence prop…
With constant development and prosperity of social economy, China's industrial domain has achieved great development, so has the chemical industry. During the specific process of chemical product manufacturing, corrosion of chemical equipment is a common phenomenon. How to effectively prevent corrosion is a significan…

Electromagnetic Metamaterial (EMM), which cannot be found in nature and possesses the novel electromagnetic properties of negative refraction, reversals of both Doppler shift and Cherenkov radiation, is a kind of artificial composed material. In order to solve the problem of long delay and high packet loss rate, the p…
It was mentioned in Section 1.1 that all nuclear reactors generate “decay heat” even after “shutdown.” In order to remove this decay heat, the reactors are equipped with safety systems or Emergency Core Cooling Systems (ECCS). Determination of this decay heat as a ratio of the reactor power after shutdown to the initi…
Reactor criticality condition and fuel conversion capability are depending on the fuel arrangement schemes, reactor core geometry and fuel burnup process as well as the effect of different fuel cycle and fuel composition. Criticality condition of reactor core and breeding ratio capability have been investigated in thi…
The porous carbon materials were prepared by the following processes of evaporation induction self-assembly (EISA), thermal polymerization process and calcination step at high temperature with the nano-zinc oxide as a hard template and phenol resin as carbon source. The as-prepared porous carbon materials were charact…
Solid polymer Blend Electrolyte System based on Na-salt has been investigated.
