The combined kinetic analysis implies a simultaneous analysis of experimental data representative of the forward solid-state reaction obtained under any experimental conditions. The analysis is based on the fact that when a solid-state reaction is described by a single activation energy, preexponetial factor and kinet…

We report the facile fabrication of a functional nanoporous multilayer film with wettability that is reversibly tunable between superhydrophobicity and superhydrophilicity with UV/visible irradiation. Our approach controls surface roughness with an electrostatic self-assembly process and makes use of the photoresponsi…

Mesoporous silica films with three different pore sizes were prepared by using cationic surfactant, non-ionic surfactant, or triblock copolymer as structure directing agents with tetramethylorthosilicate as silica source in order to control the pore size and wall thickness. They were synthesized by an evaporation-indu…

Abstract The synthesis of a novel spiro orthoester containing monomer, 1,4,6‐trioxaspiro[4.4]‐2‐nonylmethyl acrylate, is presented. This monomer was polymerized via a free‐radical system to yield the homopolymer and a series of copolymers with phosphorus‐containing comonomers. Diethyl vinyl phosphonate, allyldiphenylp…

This article reports on an experimental study of the physical and mechanical properties of Polystyrene (PS) and Fe-PS polymer composites containing 5, 10, and 15 vol.% of Fe powder. After mixing Fe powder and PS in a twin-screw extruder, an injection-molding machine was used to prepare unfilled PS and Fe-PS polymer co…

In the present work we have explored the synthesis of ZnO nanoparticles in two different alcohols, using an alkali- alcohol (forced hydrolysis) or water-alcohol mixture (self- hydrolysis) as source of OH- for initiation of the condensation reactions. Characterization of the particle size was accomplished by means of U…

Wood flour-polypropylene foamed composites, in ratios of 10:90, 20:80, 30:70, and 40:60 (wt./wt.), were prepared with and without maleic anhydride treatment of wood flour and maleic anhydride-grafted PP (MAgPP). The effects of the amount of wood flour and its treatment on the morphology, the mechanical properties, and…

We present a technology for thermoelectric generators using large area pn-junctions. Thermally generated carriers are separated by the gradient of the built-in potential caused by the pn-junction. The use of these structures for waste heat recovery implies an externally applied temperature gradient in-plane with the p…

We systematically investigate the effect of the oxygen isotope in $({\mathrm{Pr}}_{1\ensuremath{-}x}{\mathrm{Sm}}_{x}{)}_{0.7}{\mathrm{Ca}}_{0.3}{\mathrm{CoO}}_{3}$ which shows a crossover with $x$ from ferromagnetic metal to the insulator with spin-state transition. A striking feature is that effect of oxygen isotope…

A series of barium substituted ${\mathrm{La}}_{0.5}{\mathrm{Sr}}_{0.5\ensuremath{-}x}{\mathrm{Ba}}_{x}\mathrm{Mn}{\mathrm{O}}_{3}$ materials has been synthesized and investigated using neutron powder diffraction. We show that Ba substitution suppresses the low-temperature orbital ordering that has been previously obse…

This article reports on the properties of polyurethane rigid foams, which are used as insulating materials. Most polyurethane rigid foams, derived from cellular polymers, are unstable and tend to crack when acted upon by external forces. These foams are classified as a subgroup of cellular polymers, and thus their low…

A simple model of thermoluminescence (TL), in which the trap and the recombination centre exist in the same defect complex, is assumed. It is called the localized recombination model (LRM). The analytical expression derived for this model turns out to be of first order irrespective of whether the system is recombinati…

We show that densification of silica glass at ambient pressure as observed in irradiation experiments can be attributed to defect generation and subsequent structure relaxation. In our molecular dynamics simulations, defects are created by randomly removing atoms, by displacing atoms from their nominal positions in an…
