Opening up a band gap of the graphene and finding a suitable substrate are two challenges for constituting the nano-electronic equipment. A new two-dimensional layered crystal g-C2N (Nat. Commun. 2015, 6, 1--7) with novel electronic and optical properties can be effectively synthesized via a wet-chemical reaction. And…

Corrosion is a major global challenge with both economical and technological impacts. The total world-wide costs of corrosion have been evaluated to rise to over 2 000 000 million euros annually. While several methods exist for corrosion protection, atomic layer deposited (ALD) coatings have an advantage in applicatio…
This chapter describes recent advances in the preparations, characterization, and evaluation of glycoliposomes and their biomedical research and applications. Many strategies for surface glyco-functionalization of liposomes have been reported in the past decades, of which two strategies/approaches have been commonly u…
Significant progress was made on the technical, licensing, and business aspects of the Westinghouse Electric Company’s Enhanced Accident Tolerant Fuel (ATF) by the Westinghouse ATF team. The fuel pellet options included waterproofed U15N and U3Si2 and the cladding options SiC composites and zirconium alloys with surfa…
Three-dimensional confinement allows semiconductor quantum dots (QDs) to exhibit size-tunable electronic and optical properties that enable a wide range of opto-electronic applications from displays, solar cells and bio-medical imaging to single-electron devices. Additional modalities such as spin and valley propertie…
The most promising way of isolating radioactive waste from the environment is currently underground storage. Ecology-aggressive long-lived radionuclides in radioactive waste are mostly represented by transuranic elements. Therefore, it is highly important to study forms of transport of transuranic radionuclides by und…
The structure and properties of Al – Ca – Sc alloy in cast and heat-treated state were researched in comparison with AK7pch (АК7пч) silumin. Both alloys were obtained on the basis of high purity aluminium A99 (State Standard 11069–2001). Calcium was added in pure metallic form while scandium was added as an Al – 2 % S…

Nonlinear absorption has been investigated by open aperture z-scan in ionic liquids obtained by combination of 1-butyl-3-methyl-imidazolium cations with anions containing a transition metal (Zn) and thiocyanate groups. The laser source was a Ti: Sapphire oscillator (80-fs pulses, λ= 810 nm, repetition rate of 80.75 MH…
Welcome to the WIT Press eLibrary - the home of the Transactions of the Wessex Institute collection, providing on-line access to papers presented at the Institute's prestigious international conferences and from its State-of-the-Art in Science & Engineering publications.
The (1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3 (PMN-PT) (0.10 ≤ x ≤ 0.35) ceramics were prepared by the columbite method. As the PT content increases, the ferroelectric state of PMN-PT system transforms gradually from the relaxor ferroelectric state to the normal ferroelectric state. The maximum electric-field induced strain reach…
A TiO2|Co3O4|MoO3 all-oxide solar cell produced by spray pyrolysis and pulsed laser deposition (PLD) onto a fluorine-doped tin-oxide (FTO) glass substrate with gold (Au) back contacts is demonstrated for the first time. A combinatorial approach is implemented to study the effect of molybdenum oxide (MoO3) as a recombi…
A Solution state study on complexation behavior of Th(IV) with hydroxy acids (malic acid, lactic acid, salicylic acid and mandelic acid) has been carried out using the Irving–Rossotti titration technique in aqueous media and mixed media at different temperatures and ionic strengths. The dissociation constant and stabi…
Isolation of high-level radioactive waste (RAW) in deep geological formations means disposal of metal containers with radionuclides at a temperature higher than 200 °С. Placement of such containers in wells at a depth of over 500 m below surface involves long-term action of rock pressure and temperature on enclosing r…
The authors appreciate participation of A. V. Ponizov, Director of Zheleznogorsk Division, National Operator for Radioactive Waste Management in this study. Based on the 50-years experience gained in research, development and practice of liquid radioactive waste disposal in deep-level weakly permeable geological struc…
For the purpose of quality improvement and increasing of yield enhancement of image converter tubes, there was developed the synthesis technology of luminophore Gd2O2S:Tb (KFL-544 (КФЛ-544)) with average crystal size of 0.6–0.8 μm, and its output was organized for replacement of both luminophore KS-525 (КС-525) (ZnS:C…
The physical properties of aluminum Al – Mn – Cu alloys were discovered for the comparison of on-line inspection methods of chemical composition and microstructure. Measurement methods were used to determine the hardness, electrical resistivity and thermoelectric power of the samples. The investigated samples are thre…
The effect of thermal aging on the degradation of fracture toughness and Charpy-impact properties of austenitic stainless steel (SS) welds has been characterized at reactor temperatures. The solidification behavior and the distribution and morphology of the ferrite phase in SS welds are described. Thermal aging of the…
