A previously developed theory for the temperature-dependent resonance Raman scattering is used to study the surface-enhanced Raman scattering. Two models, the displaced oscillator model and the displaced-distorted oscillator model, based on the harmonic potential energy surfaces are carried out to calculate the surfac…

Abstract A monocrystal ofFe 3 O 4 is characterized by resistance, magnetoresistance and magnetic measurements in a temperature range from 4.2 K to 350 K and magnetic field-cycling from −9 T to 9 T. The resistance measurements revealed a metal-insulator Verwey transition (VT) atT v=123.76 K with activation energy E=92.…

Mehlich 3, Mehlich 2, CAL (calcium lactate), Schachtschabel, 0.01 M CaCl2, and aqua regia were compared as soil potassium extractants. Comparison was focused on the relationships between Mehlich 3 as a Czech official soil‐testing method and the extractants used for this purpose in the past (Mehlich 2, Schachtschabel)…

A two-dimensional model is developed for the modulated internal airflow, due to walking, in the gap between clothing and skin surface in the presence of clothing apertures. The normal airflow renewing the air layer through the fabric is modeled using the Ghali et al. three-node fabric ventilation model with corrected…

A SQUID magnetometer is used to study the behavior of the magnetization of TmFeO3 single crystals along the a and c principal crystallographic axes in the Γ4–Γ24–Γ2 spin reorientation range. The temperature dependences are obtained as the moduli of the magnetization vector M and its turn angle θ in the reorientation r…

This paper presents a novel constrained foaming process to produce microcellular panels. A systematic study of various process variables is conducted using a two-stage, sliding-level design of experiment approach. The resulting microcellular sheets have thicknesses in the 5 – 15 mm range and densities reductions as lo…

Abstract When deposits obtained by physical and chemical vapor deposition, electrodeposition, and electroless-deposition are annealed, they undergo recrystallization or abnormal grain growth to reduce their energy stored during deposition. The driving force for recrystallization is mainly due to dislocations, whereas…

Abstract The stability of a corrosion pit is directly related to the pit solution chemistry. In order to know the stability of a meastable pit, the product of corrosion current density and diffusion depth (pit radius for an open hemisphere pit) is compared to the stability product obtained from the artificial pit elec…

Control of light intensity and colour are two of the major features required in the realization of smart windows. We designed a bi‐functional polymer dispersed liquid crystal (PDLC) film in order to satisfy such requirements, i.e. it is able both to modulate the optical transmission, if an external electric field is a…
