Rare earth-free V-based TiV2.1 -xCrxNi0.3 (x = 0.4-1.0) alloys were prepared by arc-melting. Each alloy was composed of two phases. V and Cr constituents were mainly distributed in the primary phase, while Ti and Ni constituents were mainly distributed in the secondary phase. Maximum discharge capacity was increased w…
Dynamic contact angles of water and water-lithium bromide solution are measured on metallic surfaces (copper, steel, stainless steel and aluminum) in a wide range of roughness
A környezetvédelem napjaink egyik legfontosabb kérdése, ezáltal egyre nagyobb igény van a környezetet károsító tevékenységek szabályozására. Amellett, fizikai és kémiai mérőműszerek pontos mennyiségi adatokat szolgáltatnak a kül. szennyező anyagokról, mégsem adnak valós képet az élő szervezeteket érő szennyeződés mért…
在碱性催化条件下, 以正硅酸乙酯为前驱体，制备了一种新的、光谱性能持效的短波长减反膜。溶胶制备中，采用20氟基－1, 12－十二醇（PFG）控制了二氧化硅颗粒的结构和尺寸，从而一定程度地减小了薄膜的折射率。以PFG修饰的二氧化硅为基础，再采用甲基丙烯酸六氟丁酯的聚合物(PHFBMA)对溶胶进行改性，得到了适用于熔石英基底的PHFBMA/PFG/SiO 2 减反膜。该改性减反膜在300 nm左右可以达到99.9%的透过率，并且一定湿度条件下和含有机污染物的真空腔室内的考察结果表明，该改性膜层的透过率稳定性获得了显著提升。
In the first chapter Prof. Kozubski and colleagues present atomistic simulations of superstructure transformations of intermetallic nanolayers. In Chapter 2, Prof. Danielewski and colleagues discuss a formalism for themorphology of the diffusion zone in ternary alloys. In Chapter 3, ProfessorsSprengel and Koiwa discus…
The visible light emission spectra from gallium arsenide surface are measured at different charge states of incident ion in the wavelength range 300-700nm. For 340keV Kr q+ (q=17, 15) ions bombarded the GaAs surface, the experimental results show that intensities of spectral lines are related closely with the projecti…
Οι πολυκυκλικοί αρωματικοί υδρογονάνθρακες (ΡΑΗs) αποτελούν μία ομάδα υψηλά λιποφιλικών οργανικών ενώσεων και έχουν προκαλέσει τα τελευταία χρόνια μια αυξανόμενη προσοχή, λόγω των καρκινογενών και μεταλλαξιογόνων ιδιοτήτων τους, καθώς και της παρουσίας τους παντού στο περιβάλλον. Το βενζο[a]πυρένιο (B[a]P) είναι ένα α…

Abstract BuLi‐promoted reaction of the highly fluorinated cyclopentenes (I) with dibromopyridines (II) gives diarylethenes (III) in which the central cyclopentene ring participates in photoisomerization reactions.
The fluorescence radiation from a CsI(Tl) scintillator induced by high-energy carbon ions was investigated. The structures of the emission spectra in the ultraviolet and visible bands as well as their intensity dependence on the projectile energy are reported.
We derive the generalized magneto-absorption spectra for curved graphene nanorib- bons and carbon nanotubes by using the Peierls tight-binding model. The main spectral characteristics and the optical selection rules result from the cooperative or competitive relationships between the geometric structure and a magnetic…

Introduction Efficiency improvements in flexible DSSCs are expected by employing tailor-made ZnO. We have developed a method to quickly crystallize ZnO by microwave assisted hydrothermal reactions. Structures of these nanocrystals for shapes and sizes, as well as preferentially exposed crystal facets, could significan…
We report on our recent work in the measurements of cross sections for electron scattering from radical species.
High energy resolution reflection electron energy loss spectroscopy (REELS) spectra measurements were performed for Ni. We present the differential excitation probabilities for electrons traveling in nickel extracted from the spectra by using the Werner's elimination-retrieved algorithm. The electronic structure and o…
Experimental and theoretical research on water wettability, adsorption, and condensation on solid surfaces has been ongoing for many decades because of the availability of new materials, new detection and measurement techniques, novel applications, and different scales of dimensions. Au is a metal of special interest…
Transmission of low-energy electrons of 200 eV through a single glass capillary was investigated. The results show transmission of electrons at large tilt angles, where direct transmission should be geometrically prevented, thus indicating the existence of the guiding effect. Nevertheless, the transmitted current inte…
양어 사료의 부상시간을 연장시켜, 사료 소비율을 높이고 양식장 수질오염을 저하시키기 위해 사료에 소수성 코팅을 하였다. 상압 유전체장벽방전 플라즈마 반응기 시스템에서 헥사메틸다이실록세인(HMDSO), 톨루엔 및 n-헥세인을 전구물질로 사용하여 사료 입자의 표면에 코팅 층을 형성시켰다. 공정 변수인 플라즈마 구동을 위한 입력 전력, 전구물질 종류, 코팅시간을 변화시키며 코팅 성능을 비교하였다. 코팅된 사료 표면의 물리, 화학적 성질은 접촉각 측정기와 퓨리에 변환 적외선 분광광도계를 이용하여 조사하였다. 소수성 플라즈마 코팅 후 물의 접촉각 증가는 표면이 소수성으로 변…
It is demonstrated that local magnetic moments of single molecule magnets (SMM) normally studied by XMCD at very low temperatures and high magnetic fields can be measured by means of spin-resolved electron emission in the paramagnetic phase at room temperature by use of circularly polarized radiation.
We investigate transmission of low-energy electrons (800 eV) through a paired parallel glass plates. The measurements were focused on the angular distributions of electrons transmitted through capillary. The present results indicate that the observation angle is larger than the tilted angle ψ.
