The systematic and quantitative approach on the environmental pollution is a significant challenge in highly regulated industries, such as power plants, where a large amount of waste gas including greenhouse gas must be discharged. We simulated various CO2 reduction processes and estimated the total cost of those. In this study, an environmental pollution impact is analyzed by the process opera...

Abstract Superabsorbent hydrogels were prepared from biodegradable material, where the matrix was cross-linked cellulose and carboxymethyl reinforced by quaternized tunicate nanocrystals (Q-TCNCs). Due to large amount of hydrophilic groups on cellulose, Q-TCNCs, had excellent water absorption capacity. The equilibrium swelling ratio superabsorbent exceeded 500 g/g in deionized 120 even syntheti...

Mn1-xZnxFe2O4 (0 ≤ x 0.65) nanoferrite particles were used as filler in a silicone polymer matrix order to obtain composite material with the purpose of absorbing electromagnetic radiation. The was characterized by X-ray diffraction, transmission electron microscopy and force modulation (FMM) properties means network impedance analyzers. It observed that higher concentrations Znx (x = 0.5 prese...

The printing plate and its characteristics in the conventional printing techniques have a significant impact on print quality and image appearance. In screen printing, a weave of screen mesh i.e. a number of threads per cm, is the most important characteristic of the printing plate, hence the most relevant factor which defines printing quality. Print quality itself is a complex term that includ...

Based on the adsorption performance of composite microspheres with activated carbon (AC) and sodium alginate (SA), as well as the magnetic property of Fe₃O₄, we designed and explored an efficient strategy to prepare a unique, multifunctional Fe₃O₄/AC/SA composite absorbent (MSA-AC) that extracted dye from aqueous solution. The composite exhibited the following advantages: rapid and simple to pr...

In this paper, we consider the following problem due to Erdős: for each m ∈ N, is there a (least) positive integer f(m) so that every finite mcolored tournament contains an absorbent set S by monochromatic directed paths of f(m) vertices? In particular, is f(3) = 3? We prove several bounds for absorbent sets of m-colored tournaments under certain conditions on the number of colors of the arcs i...
