The use of radiation-induced grafting (RIG) polymerization techniques is an appealing way to create and develop polymer. method copolymerization preparation was evaluated in this paper based on the types their prospective applications. Based preparation, optimum yield monomer polymer backbone described. approach used summarise review go through polymer-related papers from science direct online ...

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...
