Interest in the chemistry of porphyrins and related tetrapyrrolic macrocycles has increased greatly in recent years because of the importance of these compounds in many areas of chemistry, biology, and material sciences.Consequently, the development of efficient synthetic strategies and intermediates for the preparati…
Plastics Engineering is the official publication of the Society of Plastics Engineers (SPE). We provide plastics professionals with a wealth of information about machinery, technological advances, materials innovations, sustainability, and more.
The article presents the results of physical and numerical modeling of the processes of thermo- plastic treatment of an experimental complex-phase (CP) steel. Numerical tests were carried out using a commercial software program, ThermoCalc. Based on the obtained test results, the austenitization temperature was establ…
The aim of this work was to understand the particle level swelling and pore structure of microfibrillated cellulose (MFC). For this purpose, a new variant of the solute exclusion test was constructed which takes into account the adsorption of dextran onto the cellulosic material and the elastic response of the fiber m…
Tilapia are one of the most widely introduced fish globally that has clearly emerged as a promising group in aquaculture. Oreochromis niloticus was the first Tilapia species to be taken up for large Scale aquaculture. It is consumed widely due to its deliciousness and rich source of protein. During its processing, the…
The nonwoven is manufactured by using chicken feathers which are available at very low cost, so the end product too. The advantage is that there is a wide range of application of chicken feathers in textile field. The nonwoven which is prepared by chicken feather has very versatile and a wide application in the field…
The behavior of nanoparticles towards proteins is an important aspect across wide areas of nanotoxicology and nanomedicine. In this chapter, we describe a procedure to study the adsorption of proteins onto nanoparticle surfaces. Circular dichroism (CD) spectroscopy is utilized to quantify the amount of free protein in…
Colloidal stability of nanoparticles in biological media is crucial to preserve their utility as aggregation often leads to undesirable biological response. A quantitative measurement of nanoparticles aggregation in solution would provide a valuable assessment of colloidal stability of bio-nano interfaces after surfac…
Effect of heavy metals such as copper, chromium, nickel and cadmium on growth of Pseudomonas as well as PGPR activity was analyzed in this study. Minimum Inhibitory Concentration (MIC) of copper, chromium, nickel and cadmium against Pseudomonas aeruginosa strains were 186.9±29.60, 88.0±12.36, 153.81±34.38 and 130.54±2…
The caustic calcined magnesite was used as an additive to produce an oxidized pellet.The effect of MgO-bearing on the compressive strength of pellet was investigated.The results showed that with the addition of MgO-bearing in pellet,the compressive strength of pellet decreases gradually.The reasons as follows:(1)the M…
Partial discharge (PD) may have long time delay from days to years depending on the size and other characteristics of voids under electric stress. Voids may be formed due to expansion and contraction of the cables. Enlargement of voids is due to chemical reaction by discharge byproducts and continuous bombardment of p…
In this report pure poly(vinylidene fluoride) (PVDF) films were prepared by casting method using acetone solvent. The crystallization of both and phase from acetone solvent by varying the time of crystallization has been described. This paper also describes the enhancement of phase at different annealing condition. ph…
Spiropyran is one of the classic photochromic compounds, which undergoes photoisomerization under ultraviolet exposure with its structure transformed from a non-polar, closed and colorless spiro-form to a highly polar, open and colorful cyanine-form with extended -electron delocalization. This has encourged researcher…
This trial was carried out to investigate the effect of combination silver nanoparticles (SNPs) and inorganic selenium (ISe) on performance traits, digestive and visceral organs of broilers during starter stage (from 1 to 21 days of broiler ages). A total of 300 one-day male broiler (Ross-308) were distributed in five…
Recognition of DNA depurination is of great importance for early cancer detection. Current analytical methods for this purpose are usually complicated. Luminescent lanthanide complexes possess some fascinating optical properties that have shown potential applications in biomedical research. In this study, a novel terb…
The reactions of the diaminebis(aryloxido) ligand precursors [Me2NCH2CH2N(CH2-4-R-C6H3OH)2] [R = C(CH3)2CH2C(CH3)3, H2L(1); R = CH3, H2L(2)] with Mg(n)Bu2, ZnEt2 and AlEt3 create complexes of general formula [M2(μ-L-κ(4)O,N,N,O)2] (M = Mg, 1a for L(1) and 1b for L(2); M = Zn, 2a for L(1) and 2b for L(2)) and [Al2(μ-L-…
We report the design, production and characterization of a biosynthetic asymmetric triblock copolymer which consists of one collagen-like and one cationic block spaced by a hydrophilic random coiled block. The polymer associates into micelles when a polyanion is added due to the electrostatic interaction between the c…
In this paper, the camphor sulfonic acid (CSA) doped polyaniline(PANI) was polymerized in m-cresol (m-c) and chloroform (ch) mixed solvent, and researches for effects of the doping parameters such as time, temperature, the amount of dopant and the ratio of m-cresol (m-c) and chloroform (ch) mixed solvent for doping on…
The silver-titania nanoparticles with various silver contents were prepared by introducing the silver onto titania surface. Presence of silver was confirmed by various analyses. Compared to neat titania nanoparticle, the silver-titania nanoparticle exhibits better visible light photocatalytic degradation of methylene…
A free-space transmission method has been used for reliable shielding effectiveness measurement of the easily available textile materials. Textiles with three different yarn densities were studied for their shielding effectiveness with the help of a vector network analyzer and laboratory calibrated two X-band horn ant…
