α-SiW11Ti/PANI electron polymer materials were prepared by using Keggin structure heteropolysilicotungstate isomers α-K6[SiW11TiO40]•xH2O as dopant. The materials were characterized by, IR, UV-Vis, SEM and XRD spectra techniques, and the degradation of organic dye congo red response under irradiation of UV light catal…
Introduction We should define what reliability science is. When a device is manufactured to provide a unique function in applications, it is generally expected that the microstructure in the device will be unchanged in its lifetime of use. Unfortunately, this is not true. In electronic device applications, we have to…
Sequential extraction of the soil by various reagents is designed to remove soil P fractions of varying solubility, with inferences to chemically defined discrete forms of P. This procedure purportedly differentiates between calcium (Ca), iron (Fe), and aluminum (Al) inorganic P fractions, as well as occluded fraction…
The objective of this work is to determine the best parameters for brazing ceramic joints of pre-metallized Al2O3 with Ti by a plasma process using amorphous ribbons of Cu49Ag45Cex alloy as the addition metal. The alloys were prepared in an arc oven, and later processed by melt spinning, varying Cerium content by 4–6%…
The paper describes how the programme of individual monitoring (IM) of internal exposure (IE) at Shelter object (SO) was designed and what results were obtained in the framework of the programme for 5 y. The main dose-forming factors of IE at SO are intakes of radionuclides of transuranium elements, (90)Sr and (137)Cs…
The anodic behavior of nickel in a sulfuric acid solution is studied with the use of combined electrochemical and radiometric measurements. In a potential range of −0.01 to 0.06 V (S.H.E.), hydrogen was found to include in nickel and decelerate its anodic dissolution.
Activated carbon was fabricated by using phenolic resin as carbon source, PEG and tween-80 as organic template, KOH as activator. The samples were analyzed by N2 adsorption. scanning electron microscopy (SEM). Cyclic voltammetry and galvanostatic charge-discharge were used to characterize the electrochemical performan…
본 연구의 목적은 3시간 오존산화 처리식용유와 pMDI를 혼합하여 고온과 중온에서의 접착제를 제조하였고, 이를 상태 인장전단 접착강도 시험을 통하여 식용유의 목재 접착제 응용 가능성을 확인하였다. 고온조건에서 3시간 오존산화 식용유의 상태 접착강도 시험 결과, 오존산화 식용유 : pMDI 비율이 1 : 0.5일 때 4.74 kgf/ $cm^2$ , 1 : 0.75일 때 7.14 kgf/ $cm^2$ , 1 : 1일 때 9.29 kgf/ $cm^2$ , 1 : 2일 때 16.53 kgf/ $cm^2$ , 1 : 3일 때 17.42 kgf/ $cm^2$ , 1 : 4일…
The corrosion behavior of iron electrodes covered with benzene plasma-deposited films was investigated in 3% solution of NaCl via potentiometric method. It was established that, at the initial stages of coating deposition, an island-type metal-coating adhesion bond prevails, which results in the low protective potency…
Composite films of 4,7-bis(4-triphenylamino)benzo-2,1,3-thiadiazole (TBT) and copper phthalocyanine (CuPc) are fabricated via protonation-coelectrophoretic deposition from nitromethane solutions of TBT/CuPc mixture in the presence of trifluoroacetic acid as a protonation reagent. A nanospheres–nanowires interpenetrati…
The effect of different additions on the protective properties of a magnetite coating prepared by the oxidation of low-carbon steel in nitrate solution at 70–98°C is studied using physical, electrochemical, and corrosion methods. The introduction of the developed addition URMP-5 to ammonium nitrate solution is shown t…
Annulenoannulenes consist of multi-annulated aromatic annulenes. In their Communication on page 13320 ff. N. Aratani, H. Shinokubo, A. Osuka, and J. Song report the efficient synthesis of meso-to-meso 2,5-pyrrolylene-bridged porphyrin nanorings. The trimer (the crystal structure is on the top left) holds a cyclic hexa…
Chemistry Adsorption of gold nanoparticles to titania surfaces has proven a promising approach to extending the photocatalytic properties of a semiconductor from the ultraviolet into the visible regime. Ide et al. explored a variation on this motif in which they expanded the layer spacing of a
A technique for determining the adhesion of a liquid-glass masonry mortar to acid-proof ceramics in anticorrosion linings is described. The results of studying adhesion in the linings under the action of certain types of chemically aggressive environments are given.
Electrochemical classification of the inhibitors of metal corrosion in acidic and neutral environments is analyzed, and its certain modification is proposed. The role of changes in the corrosion potential (which is an electrochemical factor) in the deceleration of the process is considered. Expressions for calculating…
