Renewable sources – namely, algae oil and diacids – were used for the synthesis of alkyd (ALK) and polyesteramide (PEA) polyols. The prepared polyols were characterised by Fourier transform infrared and nuclear magnetic resonance techniques and size exclusion chromatography analysis. After reaction with diisocyanate, polyols were converted to polyurethane (PU) coatings, which were then characterised by X-ray diffraction, differential scanning calorimetry and thermogravimetric analysis. The biocidal activities of the films were evaluated against Gram-negative (Escherichia coli) and Gram-positive bacteria (Staphylococcus aureus) by using the turbidity method as well as by observation of film degradation or biofilm formation by bacteria on the surface of a metal tray by using scanning electron microscopy. The PUs obtained using ALK and PEA showed better antimicrobial properties compared with PUs based on algae oil fatty amide (AOFA), monoglyceride (MG) and even an uncoated mild steel (MS) panel. The anticorrosion properties of PU coatings were evaluated by the potential dynamic polarisation (PDP) method in a 3.5wt% sodium chloride (NaCl) corrosive media. All coated samples (ALK and PEA) showed good barrier properties against corrosion compared with AOFA, MG and the uncoated MS panel. The prepared algae-oil-based PU coatings showed better chemical, mechanical, water-repellent, antimicrobial, anticorrosive and thermal properties.

Selective cyanation of aryl halides was achieved with CO2 and NH3 as the only sources of carbon and nitrogen, respectively. In the presence of Cu catalysts under low pressure (3 atm), a variety of aromatic iodides and bromides were transformed to the desired nitrile products without the use of toxic metal cyanides. Notably, olefins, esters, amides, alcohols, and amino groups were tolerated. Mechanistic studies suggest that Cu(III)-aryl insertion by isocyanate intermediates is involved. [C-13,N-15]-labeled nitriles were conveniently accessible from the respective isotope-labeled CO2 and NH3 via this methodology.

Hydroxycinnamic acid amides (HCAAs) are natural compounds with antifungal, anticancer, and anti-inflammatory activities. Extraction from plants and chemical synthesis have been the major approaches to obtain these compounds. We used a biological method to synthesize HCAA derivatives (arylalkylamines). Two genes, SHT encoding serotonin N-hydroxycinnamoyl transferase and 4CL encoding 4-coumaroyl-CoA ligase, were introduced into Escherichia coli. Using this E. coli transformant as a biocatalyst, 24 arylalkylamines were synthesized. The anti-inflammatory activities of five synthesized compounds, including N-p-coumaroyl phenethylamine, N-caffeoyl phenethylamine, N-p-coumaroyl 3-phenylpropylamine, N-p-coumaroyl 4-phenylbutylamine, and N-p-coumaroyl 4-methoxyphenethylamine, were measured. Among them, N-p-coumaroyl 4-phenylbutylamine showed the best anti-inflammatory activity.

The current study involves the biogenesis of titanium dioxide nanoparticles (TiO2 NPs) by using Moringa oleifera Lam. aqueous leaf extract for the reduction of titanium dioxide salt into TiO2 nanoparticles. The biosynthesized TiO2 nanoparticles were observed by using the UV-visible spectrophotometry, SEM, EDX and XRD analytical methods. It was confirmed that the nanoparticles are crystalline and exist in the size range of 10-100 nm. The FTIR analysis confirmed the presence of O-H (hydrogen bonding), N-H (amide), C-C (alkanes) and C-I (Iodo-stretch) functional groups responsible for the stabilization of nanoparticles. Various concentrations (20, 40, 60 and 80 mg/L) of TiO2 NPs were applied exogenously on wheat plants infected with a fungus Bipolaris sorokiniana responsible to cause spot blotch disease at different time intervals. The measurement of disease incidence and percent disease index showed the time-dependent response and 40 mg/L was reported a stable concentration of TiO2 NPs to reduce the disease severity. The effects of biosynthesized TiO2 NPs were also evaluated for agro-morphological (leaf and root surface area, plant fresh and dry weight and yield parameters), physiological (relative water content, membrane stability index and chlorophyll content) and non-enzymatic metabolites (soluble sugar, protein, soluble phenol and flavonoid content) in wheat plants under biotic stress and 40 mg/L concentration of TiO2 NPs was found to be effective to elicit modifications to reduce biotic stress. The current study highlights the significant role of biosynthesized TiO2 NPs in controlling fungal diseases of wheat plants and thus ultimately improving the quality and yield of wheat plants.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 593-81-7, Name is Trimethylamine hydrochloride, formurla is C3H10ClN.

Polymer electrolytes with high Lit-ion conductivity provide a route toward improved safety and performance of Li+-ion batteries. However, most polymer electrolytes suffer from low ionic conduction and an even lower Li+-ion contribution to the conductivity (the transport number, t(+)), with the anion typically transporting over 80% of the charge. Here, we show that subtle and potentially undetected associations within a polymer electrolyte can entrain both the anion and the cation. When removed, the conductivity performance of the electrolyte can be improved by almost 2 orders of magnitude. Importantly, while some of this improvement can be attributed to a decreased glass transition temperature, T-g, the removal of the amide functional group reduces interactions between the polymer and the Li+ cations, doubling the Li+ t(+) to 0.43, as measured using pulsed-field-gradient NMR. This work highlights the importance of strategic synthetic design and emphasizes the dual role of T-g and ion binding for the development of polymer electrolytes with increased total ionic conductivity and the Lit ion contribution to it.

Chemistry can be defined as the study of matter and the changes it undergoes.

The temperature dependence of the rheological properties of poly(ether-b-amide) (PEBA) segmented copolymer under oscillatory shear flow has been investigated. The magnitude of the dynamic storage modulus is affected by the physical microphase separation and irreversible crosslinking network, with the latter spontaneously forming between the polyamide segments and becoming the dominant factor in determining the microstructural evolution at temperatures well above the melting point of PEBA. From the rheological results, the initial temperature of the rheological properties dominated by the microphase separation and crosslinking (T-cross) structures were determined, respectively. Based on the two obtained temperatures, the microstructure evolution upon the heating can be separated into the ternary microstructure domains: homogenous (temperature below ), microphase separation dominating (between and T-cross), and crosslinking dominating domains (above T-cross). When the PEBA is heated to above T-cross, the content of crosslinking network increases with time and temperature, leading to an irreversible and non-negligible influence on the rheological, crystallization, and mechanical properties. A more pronounced strain-hardening phenomenon during the uniaxial stretching is observed for the sample with a higher content of crosslinking network.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 2026-48-4, in my other articles.

A dehydroxylative Csp(3)-N coupling reaction assisted by triphenylphosphine has been developed through electrochemical oxidation. The reaction proceeds via anodic oxidation of triphenylphosphine to generate its corresponding radical cation, followed by reacting with hydroxyl groups to form alkoxy triphenylphosphonium ions, which are trapped by azoles or amides to construct C-N bonds. This method provides an efficient electrochemical strategy of activating hydroxyl groups to form C-N bonds under mild conditions.
