In sheet metal forming, we can recognize most deformed states by using in-plane biaxial deformation and can predict the occurrence of fracture by a forming limit diagram. However, in the case of axially symmetric tensile specimens, it is known that the magnitude of hydrostatic stress or stress triaxiality largely affe…
Handfeel of fabrics made of cotton, polyester and wood-based cellulose fibers lyocell, modal and viscose was assessed by Fabric Touch Tester (FTT), Tissue Softness Analyzer (TSA), ring pull-through and PhabrOmeter® and compared with human handfeel ranking. Additionally, the effect of repeated washing and drying on fab…
The corrosion resistance of stainless steels depends on a protective, passive film being formed at the steel surface on exposure to the service environment. The use of fusion welding for fabrication leads to local compositional variations within the material, which may significantly alter the stability of the passive…
Materials discovery and optimization has driven the rapid technological advancements that have been observed in our lifetimes. For this advancement to continue, solid-state chemists must continue to develop new materials. Where do these new materials come from? In this review, we discuss the approaches used by the zur…
Highly crystalline, luminescent YPO4:Tb (core), YPO4:Tb@LaPO4 (core/shell) nanorods (NRs) were prepared by urea based co-precipitation process at low temperature. The synthesis method involves important advantages such as its simplicity, low-cost precursor, eco-friendly, rapidness and high reaction yields. X-ray diffr…
Current progress in nanotechnology provides a new hope for the substantial development in the success of cancer therapy particularly in controlling tumor growth and development. PEGylated citric acid dendrimers are biocompatible compounds being developed with an aim to target the myeloid cells, from which leukemia sta…
Recently in coal-fired boiler of Japan, a water wall tube damage such as fireside corrosion and circumferential cracking in a reducing atmosphere due to low NOx environment has become a serious issue. And the improvement of the corrosion resistance of the furnace wall is required. In order to apply the Ni-based Alloy…
This paper demonstrates 4 nonlinear regressions that it was determinate (with R2 > 0.99) in the OriginPro 8 SRO v8.0724 (B724) software from the DSC experimental result obtained from a Ni50Ti30Hf20 .at% metallic alloy with Shape Memory Effect
The addition of small amount of cellulose nanofibers to biobased polyurethane based foams is leading to a foam which have similar properties as commercial rigid PU foams but with lower density and improved properties for the final sandwich laminate.
The current paper presents results of study of composites produced by compression moulding of sheets of comingled PLA and reinforcing fibers. The dynamic sheet former is employed to produce fiber mats (with the PLA in the form of fibers) which are consolidated into composite plates by using hot press. This processing…
In the last decade, the favorable properties of the press hardening process for advanced high strength steel (AHSS) have increased the demands concerning passenger safety and lightweight design. AHSS show excellent mechanical properties from e.g. tensile test measurements, but it has previously been shown that results…
Представлены результаты исследования зоопланктона двух внутриболотных первичных озёр, расположенных в центральной (оз. Шиченгское) и краевой (оз. Полянок) частях крупного болота Шиченгское (Вологодская область). Всего обнаружено 60 видов (20 Rotifera, 26 Cladocera, 14 Copepoda). Таксономическая структура зоопланктон в…
Current trends in the field of Fibre Reinforced Plastics (FRP) are exceeding the capabilities of classical, recognised inspection and test methods. Novel non-destructive measurement methods to easily assess the quality assurance within an industrial mass production are required. The research undertaken by the Centre f…

Functionalization of drug carriers using engineered inorganic nanoparticles (NPs) is currently an important topic.Polyelectrolyte microcapsules, as one of potential drug delivery systems, can be facilely functionalized with various modifiers including inorganic NPs.In recent years, gold NPs, Fe3O4 and ZnO were incorpo…
アパタイト骨セメントは，準安定形リン酸カルシウムからなりヒドロキシアパタイト（HAP）への転移により自己硬化する。このセメントに種々の薬剤を練合して薬剤徐放性人工骨セメントを調製した。 アパタイト骨セメントからのin vitro薬物放出速度はHiguchi式に従ったことから，薬物濃度，空隙率，セメント粒子径，拡散係数などにより薬物放出制御が可能であった。In vitroとin vivo実験の結果から，アパタイト骨セメントからのin vivo薬物放出特性は，生体液中のカルシウム濃度に依存する薬物放出であることを証明した。このことからアパタイト骨セメントは，骨親和性の高い低結晶性HAPに転移して自己硬化し，骨粗鬆症病態に応答する薬物放…
After longitudinal compression the natural wood will be bent easier. The relaxation after compression results in better properties. The maximum deflection increases with the relaxation time and with the decreasing of the modulus of elasticity (MoE), while the needed force for the same bending also decreases. The bendi…
Understanding the magnetic properties of materials used in accelerator components is becoming more and more important. For example, in the upcoming LHC upgrade at CERN, the increasing luminosity will boost the radiation dose received by the accelerator magnet's coil and consequently decrease its lifespan. Hence, a rad…
