The organic/inorganic hybrid coatings have been intensively studied in recent years and it have been reported that the incorporation of inorganic components enhanced both the corrosion resistance and adhesion of organic coatings.The UV radiation has been widely used to cure coating resins for many years.The UV-curing…
Ru nanoparticles have been deposited onto a multi-walled carbon nanotube paper (Ru@MWCNTP) via a wet chemical method. The resulting catalyst, Ru@MWCNTP has been demonstrated to significantly reduce the charge overpotentials of the Li–O2 battery at a current density of 500 mA g−1. The reversible formation and decomposi…
Comparative analysis of the results of physical and computer modeling of pressure welding of coarse-grained HN58MBYUD heat-resistant nickel alloy using ultrafine-grained gasket is presented. According to the results of numerical simulation of the stress strain state, maximal values of strain are observed in the periph…
(APS) as an oxidant in the aqueous medium,and nanofibers produced by electrospinning . Electrospun nanofiber mats were by treated heat under air atmosphere to be stabilized. Nanofiber production from AN-IA copolymers and suitability of the nanofiber as carbon nanofiber precursor is discussed. Copolymer are characteriz…
Burn marks are serious defects that can occur during injection molding, and from the viewpoint of the molding engineer, are a problem that urgently needs to be solved. In the present study, a gas collection and component analysis system was used to determine the gas production mechanism during injection molding of PBT…

Origami, the Japanese art of paper folding, has seen a recent shift from a traditional art form to a platform for design of structures capable of actuation.These structures are capable of reconfiguration into multiple defined geometric states by rotation about pre-defined lines in a grid.Thus far, research in the orig…
Water borne acrylamide based curing agents were prepared from acrylamide, formalin and methanol. The curing agents were characterized for their various physico-chemical characteristics. High performance coatings based on water compatible epoxies and above curing agent were than prepared by blending them in a various r…
In order to routinely operate the LHC with 25 ns bunch spacing during Run 2,\nelectron cloud effects will have to be mitigated through beam induced scrubbing.\nTherefore, the Run 1 experience with 25 ns beams will be reviewed and used for\ndefining the most effective scrubbing strategy. In particular, the potential of…
It has been highlighted the importance of huntite/hydromagnesite mineral as an innocent flame retardantmaterial in the plastics in our previous works. In this study, flame retardant behaviors of huntite and hydromagnesite in the polymeric dye coatings were obtained and thesize dependence of this circumstance has been…
Crossed helical gears are used in cars and in many household appliances.The trend towards increased comfort in motor vehicles has led to the utilisation of more than a hundred servo-drives in luxury class automobiles.Important advantages of crossed helical gears are their easy and inexpensive design, low noise perform…
This volume contains the abstracts presented at the 14th European Mechanics of Materials Conference (EMMC14), held at Chalmers, Göteborg, Sweden, on September 27-29, 2014. The ever increasing development of new engineering materials required to meet advanced technological needs poses new challenges in the field of mec…
A phytochemical investigation on the roots of Dracaena marginata yielded nine steroidal saponins. Six of the saponins were isolated as three pairs of 22-hydroxy furostanol saponins and their 22-methoxy derivatives including two new minors identified as 26-O-β-D-glucopyranosyl-22α-hydroxy-(25R)-furost-5- en-3β, 26- dio…
This report describes the production of ERM®-EB530A, B and C, aluminium gold alloy material certified for the mass fraction of gold. The material was produced following ISO Guide 34:2009.\nPure aluminium and pure gold were arc melted together to obtain a master alloy Al-5%Au (mass percent). The master alloy was melted…
Man is continuously being exposed to radiation due to its presence everywhere on earth. This study is aimed at determining the radium equivalent activity from the soil samples collected from different locations around a superphosphate fertilizer factory in Nigeria. An efficiency and Energy calibrated high purity germa…

製材の強度に寸法効果が存在することは国際的にも知られているが，我が国の軸組構法の構造部材として使用される構造用製材の規格に寸法調整係数は採用されていない。そこで，スギ製材の曲げ強度に対する寸法効果を明らかにするため，丸太からサイドマッチング及びエンドマッチングによって試験体を採取し，曲げ強度に及ぼす材せい及び材幅の影響について検討した。材せいの影響は，材幅を140mmに一定として材せいを300mm，170mm，105mmの3種類について，材幅の影響は材せいを150mmに一定として材幅を150mm，105mmの2種類について，それぞれ標準試験条件によって曲げ試験を実施した。その結果，曲げ強度の平均値は材せいの減少にしたがって増加する…
