Thermowood is a relatively new material, which is being increasingly used for the manufacturing of products designed for use both from outside and inside the premises. However, due to changes in the wood chemical composition, due the action of high temperature and the relative novelty, this problem of the ability of s…
Abstract The nonlinear interaction of a four-level atomic configuration in potassium, with ns pump and coupling fields, is numerically investigated. The resonant pump acts on the two-photon transition ∣ 4 S 1/2 〉 ↔ ∣ 6 S 1/2 〉 causing internally generated emissions in two atomic paths: path-1, ∣ 4 S 1/2 〉 ↔ ∣ 6 S 1/2…
The role of reactive environment and hydrogen specifically in growth and structure of molybdenum selenide (MoSe 2 ) nanomaterials is presently debated, and it is not clear whether hydrogen can promote the growth of MoSe 2 sheets and alter their electronic properties. To find efficient, convenient methods for controlli…
CrystalWalk is a crystal editor and visualization software designed for teaching materials science and engineering. Based on WebGL/HTML5, it provides an accessible and interactive platform to students and teachers by introducing a simplified crystallographic approach that creates crystal structures by combining a latt…
ZIF‐8 particles show excellent selective adsorbing ability for methyl blue (MB). However, the main problem of ZIF‐8 particles as adsorbents is the difficulty of recovery from residual solution after use due to the nano‐sized dimension. In this study, ZIF‐8 particles were embedded into polyethersulfone (PES) polymer an…
As a fused‐ring conjugated unit, triphenodioxazine, has been applied in two series of thiophene‐free conjugated polymers for polymer solar cells. The polymers were synthesized through a multi‐step synthetic route, and the substituents had a great effect on the reactivity of the reactants. Relationships among the polym…
Abstract In this paper, the dynamical behavior and stability of hanging micropipes conveying fluid with pinned-free boundary conditions are investigated. For a pinned-free rigid micropipe, the dynamical system is found to be stable for various flow velocities. Particular emphasis is placed on the effects of flow veloc…
Soy protein (SP) which exists in soy flour, soybean meal, soy protein concentrate, and soy protein isolate is one of the vegetable proteins. It represents a very practical and inexpensive material for bio-based adhesives. The positive public perception of SP makes it very competitive as a wood adhesive. While SP is we…
Abstract In the context of value added valorization of hemicelluloses (HCs), their soft extraction by autohydrolysis (AH) of softwood (SW) chips has been optimized via the temperature/time parameters (170°C/2 h, 170°C/1 h and 150°C/1 h). Two enzyme mixtures containing mainly a glucanase and a mannanase were used to de…
Effectively, two-dimensional (2D) closed films exhibiting in-plane orientational ordering (ordered shells) might be instrumental for the realization of scaled crystals. In them, ordered shells are expected to play the role of atoms. Furthermore, topological defects (TDs) within them would determine their valence. Name…
Over the last few decades, electrostatic precipitators (ESPs) have emerged as effective air pollution control devices for treating coal-fired power plant exhausts. Among the components of the ESP, the discharge electrodes are extremely important in determining the collection efficiency of the ESP. Typically, in wet ES…
The copper electron paramagnetic resonance gyromagnetic factors are theoretically studied for three novel Cu2+ coordination polymers [Cu(XL)(NO3)2]n (1), {[Cu(XL)(4,4′‐bpy)(NO3)2]•CH3CN}n (1a) and {[Cu(XL)3](NO3)2•3.5H2O}n (2) with bi‐triazole ligand (XL) = N,N′‐bicyclo[2.2.2]oct‐7‐ene‐2,3,5,6‐tetracarboxdiimide bi(1,…
Effects of different mechanical deformations such as cyclic bending and compressive flexing and temperature on electrical and dynamic mechanical properties of elastomeric composites have been investigated. Conductive elastomeric composites were prepared by incorporating different carbon blacks in an insulating polychl…
Monolayer films modified polycrystalline gold electrode has been fabricated by using self assembled monolayer method of 1,6-hexanedithiol and 1-hexanethiol and used for electro-catalytic oxidations of iron(II). A calibration curve was obtained for Fe(II) in a wide concentration range from 5.00×10 -8 mol.L − 1 to 3.85×…
In this work, we use conductance and contact potential difference photo-transient data to study the influence of the growth technique, doping, and crystal polarity on the kinetics of photo-generated charges in GaN. We found that the processes, and corresponding time scales, involved in the decay of charge carriers gen…
Abstract In this work we investigate design parameters enabling normally-off operation of zincblende (ZB-) phase Al X Ga (1− X ) N/GaN high electron mobility transistors (HEMTs) via Synopsys Sentaurus Technology Computer Aided Design (TCAD). As ZB-phase III-nitrides are polarization-free, the 2D electron gas (2DEG) ch…
Cleanable dust filter media are typically used in huge baghouse filter apparatuses. Thereby, the regeneration by back-pulsing from the clean gas side is done by either time-controlled or pressure-controlled operation, whereas the latter is more common. Hence, the need for a detailed knowledge of the clogging and filtr…
This paper shows the influence of the manufacturing process of a claw-pole alternator on its acoustic noise. First, the stator welds and the assembly of the stator in the brackets are linked to deformations of the inner diameter of the stator. Then, the influences of these deformations on the magnetic forces and the s…
This letter presents a novel design of the third-order dual-band filter operating in the frequency band 10-15 GHz. The filter consists of two rectangular cavities filled with foam dielectric and connected by an ultrathin waveguide channel, which mimics the epsilon-near-zero metamaterial. Each resonator is designed to…
The rapid increase in energy consumption, limited fossil fuel resources, and environmental concerns have stimulated research need for biomass- derived fuels and chemicals. Pyrolysis is a thermal degradation process of biomass in the absence of oxygen. The liquid product from pyrolysis is known as bio-oil. Currently, i…
