Microporous polymer scaffolds decorated with nanoparticles could provide functional membranes that are \nneeded in solar-to-fuel technologies. Therefore, efficient prodn. processes are needed for high surface area, \nporous membranes with distinct catalytic nanoparticles on opposite sides of a support that resists oxi…
Unpredictable climatic conditions paired with the varying topography in Vermont have often resulted in dangerous roadway conditions. Statistics show that many fatalities occur in rural environments like Vermont. Federal Highway Administration (FHWA) has developed many strategies to address this issue. One experimental…

This is a report of Madera South's progress in meeting the twelve quality criteria.
Ausgehend von einem Forschungsprojekt zur Dauerhaftigkeit von ultrahochfestem Beton wurde ein deterministisches Modell zur Abschaetzung des Korrosionswiderstands von Beton gegenueber chemischem Angriff hergeleitet. Der Korrosionswiderstand ist abhaengig vom ebenfalls abgeleiteten Gefuegewiderstand, der den Widerstand…
The scripts 0 and 1 have to be installed in the library, while 2 and 3 can be installed as menus. Please install the scripts in order. Open the oxide wizard from the menu, then, follow the instructions. When dealing with a large spectrum image, script 3 can be called from the menu to transform the spectrum image to a…
Diamonds and silicon wafers are prized materials that share a common crystal structure. Tetrahedral atom interactions are the basis for their properties: hardness, thermal conductivity, electrical non-conductivity, etc. sp3-Hybrid orbitals provide the current explanation for the interatomic “bond” connections. These c…
The suitability of using Iranian grown giant milkweed fibers (GFs) as a new raw material for thermoplastic composites was investigated. The polypropylene (PP) was used as the matrix polymer and the maleated polypropylene, Epolene G- 3003TM, was used as coupling agent. In the sample preparation, four levels of fiber lo…
Intercalated alkali metal fullerides, which have been recently demonstrated promising hydrogen storage materials, \nhave been prepared and characterized by muSR spectroscopy, known technique for the study of the interaction of the hydrogen atom with matter. The hydrogenation mechanism has been clarified and highligted…
日本が今後、二酸化炭素（CO2）排出削減を進めていくためにはどのような対策が必要であるのかを探るため、二酸化炭素排出量の多い鉄鋼工業と化学工業に焦点を当て、温室効果ガス排出量の削減目標の基準年となっている1990年以降のCO2排出削減を促進する経済・政策要因の特定とその効果を検証した。分析結果から、エネルギー集約の高い鉄鋼業は、1990年以降はエネルギー原単位の改善がみられないことから、省エネルギー対策の効果は1990年代から薄れてきたことが分かった。一方で、二酸化炭素原単位は、エネルギー効率化や使用燃料の削減、技術改善や再生可能エネルギーの導入などにより、炭素集約の少ない燃料への転換などを通じた改善の余地があることが示された。ま…
[if gte mso 9]> In the present work, the thermal conductivity coefficients of nanoparticle-oil suspensions for two types of carbon nanotubes, single-walled (SWNTs) and multi-walled (MWNTs) carbon nanotubes at 0.1, 0.2 and 0.3 wt.% were measured by a modified transient hot wire method (KD2-pro thermal property meter).…

This article, originally published in December 1980 MP, is based on the late author’s 40 years of experience in corrosion engineering and considers the meaning of “professionalism” as it applies to the corrosion engineering profession. Subject matter includes both ethical approaches and possible abuses, as well as how…
Laser processing allows to concentrate high level of energy on material surface and the increase of surface hardness can be reached by receiving of uniform fi e-grained structure with impurities of the carbide-containing phases uniformly distributed in matrix. Analysis of properties of H12MF steel after processing by…
Zirconium alloys are active in the molten state and tend to react with the mold during casting. The casting technology of zirconium is not yet well established; especially in selecting the mold materials, which are difficult to determine. In the present work, the interfacial reactions between zirconium casting and cas…
The following study aims to quantify the release activation energy (Ea) of hydrogen (H) from lattice sites, reversible or irreversible, where the H can be trapped. Moreover, enthalpy changes associated with the main hydrogen (H) trapping sites can be analyzed by means of differential scanning calorimetry (DSC). In thi…
The article presents how to obtain copper matrix composite with alloy particles of NiCrBFeAl as complementary phase. The samples were obtained by powder metallurgy methods using different percentages of the additional phase: 20, 30, 40, 50% NiCrBFeAl of 60 µm average size. After cold pressing to 863 MPa pressure, the…
Arch structures of long span buildings’ coverings are more beneficial in respect to material expenses, than beam and frame systems. Constructive schemes of roof frameworks of arch coverings are diverse, which means their operation under loading differs much. The authors offer a number of construction solutions for fla…
Lamella flower-like ZnO was prepared in a large-scale via a simple wet chemical method at room temperature(25 ℃) using polyvinylpyrrolidone(PVP) as template and zinc nitrate and sodium hydroxide as source materials. The effects of experimental parameters such as the amounts of reagents, the reaction time and temperatu…
A novel anionic epoxy emulsifier EP-D was synthesized by epoxy resin E-44, 2-amino-5-sulfobenzoic acid, ethylene glycol monobutyl ether and butyl alcohol. Nonionic epoxy emulsifier EP-PEG was synthesized from E-44 and poly(ethylene glycol)(PEG6000) with molar ratio of 2∶1. EP-D/EP-PEG composite emulsifiers were obtain…
