It is necessary to measure the performance of outdoor/protective clothing materials in terms of comfort properties under dynamic enduse conditions. A vertical type human-clothing-environment simulator was used to evaluate the thermal comfort performance of layered textile materials under dynamic conditions. Fabric lay…
To define the origin of the electronic excited states of single-walled carbon nanotubes, femtosecond fluorescence up-conversion and frequency-resolved transient absorption measurements were used for selective excitation/probing of particular nanotubes in a micelle-dispersed preparation enriched with individual nanotub…
This paper presents a new approach in tomographic instrumentation for agriculture based on Compton scattering, which allows for the simultaneous measurements of density and moisture of soil samples. Compton tomography is a technique that can be used to obtain a spatial map of electronic density of samples. Quantitativ…
The corrosion resistance of 17-4PH powder injection-molded (PIM) martensitic stainless steel (SS) was evaluated in naturally aerated sodium chloride (NaCl) solution (3 wt%) at 25°C. This resistance was investigated by analyzing the curves of the evolution of open-circuit potential with time (Eocp vs. time), electroche…

The equations of dislocation kinetics are used to theoretically analyze the mechanism of strain hardening and the formation of fragmented dislocation structures in metals at large plastic strains. A quantitative analysis of the available data on aluminum and an aluminum-magnesium alloy shows that strain hardening at l…
Abstract Heterogen katalysierte Reaktionen sind von enormer technischer Bedeutung. Zahlreiche Prozesse laufen an der Oberfläche fester Katalysatoren mit hoher Geschwindigkeit und Selektivität ab. Durch moderne Methoden haben wir mittlerweile detaillierte Einblicke in den Ablauf vieler katalytischer Reaktionen gewonnen…
The FERMO concept was successfully applied to the Pearson's Hard and Soft acid-base principle for four ambidentate ligands. Using an intuitive statement based on the HOMO-LUMO approach to the hardness and softness, the FERMO-LUMO gaps correctly describe the soft and hard sites in the studied systems. Moreover, Kohn-Sh…
Feast and famine cycles are common in activated sludge wastewater treatment systems, and they select for bacteria that accumulate storage compounds, such as poly-beta-hydroxybutyrate (PHB). Previous studies have shown that variations in influent substrate concentrations force bacteria to accumulate high levels of rRNA…
The "318 Blackout Incident" at the Maanshan Nuclear Power Station on March 18, 2001, is considered to be the most serious event over the 24-year history of nuclear power generation in Taiwan. This paper simulates a special overvoltage phenomenon that occurred 4 h before the blackout event, which could have caused the…
The literature concerning the behaviour of metals at strain rates from quasi-static to ultrahigh is reviewed. Deformation mechanisms that are operative include twinning and adiabatic shear banding. These are functions of material strength, composition and microstructure. Behaviour of metals at ultra-high strain rates…
For ferroelectric random access memory (FRAM) to be beneficial in future mobile devices, high-density FRAM with nm scaled cell should be developed. We have succeeded in scaling further the cell size of one-pass transistor and one-storage capacitor (1T1C) FRAM down to 0.27 µm 2 at 150 nm technology node. Owing to new S…
Ag-rich tourmaline crystals were synthesized at 750 °C, 200 MPa H 2 O, and f O₂ = log (NNO) - 0.5, starting with an oxide mix of dravite composition to which various reagents, including AgF and AgCl, were added. Tourmaline containing up to 7.65 wt% Ag2O was synthesized, and this is the first time a tourmaline is descr…
Thin films of Co3O4 have been successfully deposited on SiO2/Si(100) and MgO(001) substrates by atomic layer deposition (ALD) using the precursor combination CoI2/O2. The deposition temperature was found to have a strong influence on the growth rate. On SiO2/Si(100) substrates, growth rates of about 0.2 nm per cycle w…
The radioactive by-products contained in an entire series of target foil, [18O]H2O and synthesis apparatus were identified and quantified. From the perspective of waste management, 60Co induced in Havar foil should be taken into consideration. Because the exempt activity of 60Co in BSS is 0.1 MBq, the used Havar foil…
The efficient development of hypergolic fuels requires an interdisciplinary approach involving ab initio modeling, synthesis, and experimental physical chemistry. Candidate molecules must exhibit hypergolic ignition delay times that are fast enough to warrant further testing for safety and performance criteria. Hyperg…
The 4,n-alkyloxybenzoic acid 6OBAC has a very rich variety of crystalline structures and two nematic sub-phases, characterised by different textures. It is a material belonging to a family of liquid crystals formed by hydrogen bonded molecules, the 4,n-alkyloxybenzoic acids (n indicates the homologue number). The homo…
The authors proposed a new type of gas sensor for high sensitive detection of decomposition products generated by partial discharge (PD) in SF/sub 6/ gas. The sensor employed carbon nanotubes (CNTs) as gas sensing transducer and was fabricated by electrokinetic manipulation of CNTs using dielectrophoresis. Due to comp…
Nous avons resolu la structure cristalline de l'allochalcoselite, Cu+Cu2+5Pb02(Se03)2Cl5, nouvelle espece minerale provenant des fumerolles du volcan Tolbachik, dans la peninsule de Kamchatka, en Russie, avec des donnees en diffraction X prelevees sur monocristal, traitees par methodes directes, et affinees jusqu'a un…
The concept of syncrystallization was reinvestigated by focusing on phthalic acid (PA) grown with methyl red (MR). Crystals are alternately red and yellow in adjacent growth sectors. X-ray structures of MR and its cocrystals, revealing MR in the neutral, zwitterionic, and protonated states, as well as measurements of…
