Streszczenie:

Single crystals of pure and ammonium chloride-doped urea L-malic acid (ULMA) were grown by slow evaporation technique. Many interesting results on several properties of ammonium chloride impurity added to ULMA single crystals have been observed and studied. The different morphology of ammonium chloride-doped ULMA crystals was noticed and the effect of ammonium chloride doping on the growth, optical, and hardness properties has been investigated. The presence of functional groups has been estimated by FTIR analysis. The lattice parameters of the grown crystals were studied by single crystal X-r

The cationic surfactant-octadecyl trimethyl ammonium chloride was added to the mixture of sepiolite powders and water with mechanical stirring. The effect of cationic surfactant on the defibering of fiber bundles was studied. The samples were characterized by X-Ray diffraction (XRD), bulk density, scanning electron microscope (SEM), FT-IR spectrum (FTIR) and thermal conductivity. The results indicated that the surface active agent could protect the structure of sepiolite fibers effectively, the bulk density and the thermal conductivity of the fibers could reach 0.06g/cm3 and 0.042W/(m.K), resp

The sulfonamide bearing imidazole derivatives have been synthesized via two stages of chemical reactions. In a first stage, various substituted benzaldehyde condensed with benzil and ammonium acetate in presence L-Proline served as green catalyst. In a second stage, the series of substituted imidazole derivatives were reacted with benzene sulfonyl chloride in the presence of triethyl amine base. All synthesized compounds were characterized by various spectral techniques like UV-Visible, FTIR and <sup>1</sup>H NMR spectral analysis respectively.

Sodium polyphosphate-crosslinked starch was synthesized by using cassava starch and sodium polyphosphate as main material and crosslinked agent individually. On above basis, double crosslinked amphoteric cassava starch resin was synthesized by N,N'-methylene bisacrylamide as inner-crosslinked agent, dimethyl diallyl ammonium chloride (DMDAAC) and acrylic acid as amphoteric grafted monomer. The product was characterized by infrared spectrum (FTIR). The results indicate that the cassava starch was modified successfully, and the final product was double crosslinked amphoteric cassava starch resin

N-(2-hydroxyl) propyl-3-trimethyl ammonium chitosan chloride (HTCC), a quaternized chitosan derivative, has been shown to exhibit a broad spectrum of antimicrobial activity, especially against bacteria and enveloped viruses. Despite this, molecular docking studies showing its atomic-level mechanisms against these microorganisms are scarce. Here, for the first time, we employed molecular docking analyses to investigate the potential antibacterial activity of HTCC against Staphylococcus aureus and its antiviral activity against human immunodeficiency virus 1 (HIV-1).

Magnetic wood is a composite material that achieves harmony between both woody and magnetic functions through the active addition of magnetic characteristics to the wood itself. In addition to showing magnetic characteristics, magnetic wood offers low specific gravity, humidity control and acoustic absorption ability. It has potential for broad applications in the fields of electromagnetic wave absorption, electromagnetic interference shielding, furniture, etc. This work reports on the synthesis of Fe3O4 nanoparticles (NPs) in wood from three tropical species (Pinus oocarpa, Vochysia ferrugine

Abstract Quaternary ammonium based biocides have been used for microbiological control in industrial water systems for more than 40 years. While they have good activity versus algae, they can cause problems with foaming or react negatively with anionic additives. More recently, quaternary phosphonium based biocides have been introduced. While they overcome some of the issues with quaternary ammonium based biocides, they lack surface activity and are incompatible with halogens. We report here on a new quaternary phosphonium biocide based on tributyl tetradecyl phosphonium chloride (TTPC). TTPC

Abstract Quaternary Cationic Biocides (ammonium and phosphonium based) are broad spectrum and fast acting. Due to their compatibility, low cost, and high effectiveness, they are often used as biocides in oil and gas operations alone and also as formulation components for multi-biocide packages. They have also found use as additives in corrosion inhibitor formulations, emulsifiers, nonemulsifiers, and even as scale inhibitors. While they tend to work well in fresh water where there is little to no salt present, they are shown to provide decreasing performance as the salt concentration increases

Semiconductor and magnetic nanoparticles hold unique optical and magnetic properties, and great promise for bio-imaging and therapeutic applications. As part of their stable synthesis, the nanocrystal surfaces are usually capped by long chain organic moieties such as trioctylphosphine oxide. This capping serves two purposes: it saturates dangling bonds at the exposed crystalline lattice, and it prevents irreversible aggregation by stabilizing the colloid through entropic repulsion. These nanocrystals can be rendered water-soluble by either ligand exchange or overcoating, which hampers their wi
