Fathy, E. S. published the artcileFabrication and characterization of gamma-irradiated nanomarble/acrylonitrile and styrene butadiene rubber nanocomposites, Recommanded Product: 3-(Trimethoxysilyl)propan-1-amine, the publication is Polymer Engineering & Science (2022), 62(5), 1538-1548, database is CAplus.

A comparative study on two nanocomposites based namely on acrylonitrile-butadiene (NBR) and styrene-butadiene (SBR) synthetic rubbers, reinforced by varying ratios of waste nanomarble particles (WM) was carried out. Silane which served as coupling agent was applied in treating waste marble (TWM) and the characters of the prepared nanocomposites before and after treatments were examined Nanocomposites were fabricated using a laboratory roll mill and pressed under heat, then irradiated with γ-rays at 100 kGy. Filler characterization, using the techniques transmission electron microscopy (TEM), FTIR spectroscopy, and X-ray diffraction (XRD) were discussed. TEM micrographs revealed that though untreated WM particles were within the nanometer scale, however showed incremental reduction in size via silane treatment. Mech. parameters, thermal stability, FTIR and SEM (SEM) of the advanced NBR and SBR nanocomposites have been studied. Filler loading with 5 wt% led to remarked improvement in the tensile strength (TS), modulus of elasticity (M₁₀₀), and tearing strength of the NBR nanocomposite samples. Meanwhile, elongation at break of SBR nanocomposites exhibited regressive behavior. Thermal stability testing of pristine NBR and SBR specimens demonstrated adverse features by compounding with untreated and treated waste nanomarble. Furthermore, gamma irradiated NBR nanocomposites reinforced with TWM indicated appreciable development at all thermogravimetric stages. Whereas, irradiation of SBR nanocomposites with a gamma integral dose of 100 kGy resulted in slight enhancement in thermal stability.

Maleky, Sobhan published the artcileTetracycline Adsorption from Aqueous Media by Magnetically Separable Fe3O4@Methylcellulose/APTMS: Isotherm, Kinetic and Thermodynamic Studies, Computed Properties of 13822-56-5, the publication is Journal of Polymers and the Environment (2022), 30(8), 3351-3367, database is CAplus.

This study aimed to synthesize Fe₃O₄@Methylcellulose/3-Aminopropyltrimethoxysilane (Fe₃O₄@MC/APTMS) as a new magnetic nano-biocomposite by a facile, fast, and new microwave-assisted method and to be utilized as an adsorbent for tetracycline (TC) removal from aqueous solutions Fe₃O₄@MC/APTMS was characterized by Fourier transform-IR (FTIR), Field emission SEM (FESEM), Energy dispersive spectroscopy (EDS), Mapping, X-ray diffraction (XRD), Thermal gravimetric anal. (TGA), Brunauer-Emmett-Teller (BET) and vibrating sample magnetometer (VSM). The point of zero charge (pHzpc) value of the nano-biocomposite was estimated to be 6.8 by the solid addition method. Optimum conditions were obtained in TC concentration: 10 mg L^-1, adsorbent dosage: 80 mg L^-1, contact time: 90 min, and solution pH 6 with the maximum TC removal of 90% and 65.41% in synthetic and actual samples, resp. The kinetic and isotherm equations pointed to a pseudo-second order kinetic and Langmuir isotherm optimum fitting models. Based on the values of entropy changes (ΔS) (50.04 J/mol k), the enthalpy changes (ΔH) (9.26 kJ/mol), and the neg. Gibbs free energy changes (ΔG), the adsorption process was endothermic, random, and spontaneous. The synthesized adsorbent exhibited outstanding properties, including proper removal efficiency of TC, excellent reusability, and simple separation from aqueous media by a magnet. Consequently, it is highly desirable that Fe₃O₄@MC/APTMS magnetic nano-biocomposite could be used as a promising adsorbent for TC adsorption from aqueous solutions

Rahimi, Fatemeh published the artcileNitrogen-rich silicon quantum dots: facile synthesis and application as a fluorescent ‘on-off-on’ probe for sensitive detection of Hg²⁺ and cyanide ions, Quality Control of 13822-56-5, the publication is Luminescence (2022), 37(4), 598-609, database is CAplus and MEDLINE.

The sensitive and reliable detection of Hg²⁺ and CN^– as harsh environmental contaminants are of great importance. In view of this, a novel ‘on-off-on’ fluorescent probe based on nitrogen-rich silicon quantum dots (NR-SiQDs) has been designed for sensitive detection of Hg²⁺ and CN^– ions in aqueous medium. NR-SiQDs were synthesized using a facile, one-step, and environment friendly procedure in the presence of 3-aminopropyl trimethoxysilane (APTMS) and ascorbic acid (AA) as precursors, with L-asparagine as a nitrogen source for surface modification. The NR-SiQDs exhibited strong fluorescence emission at 450 nm with 42.34% quantum yield, satisfactory salt tolerance, and superior photostability and pH stability. The fluorescence emission was effectively quenched using Hg²⁺ (turn-off) due to the formation of a nonfluorescent stable NR-SiQDs/Hg²⁺ complex, whereas after the addition of cyanide ions (CN-), Hg²⁺ ions could be leached from the surface of the NR-SiQDs and the fluorescence emission intensity of the quenched NR-SiQDs fully recovered (turn-on) due to the formation of highly stable [Hg(CN)₄]^2- species. After optimizing the response conditions, the obtained limits of detection were found to be 53 nM and 0.46μM for Hg²⁺ and CN^–, resp. Finally, the NR-SiQD-based fluorescence probe was utilized to detect Hg²⁺ and CN^– ions in water samples and satisfactory results were obtained, suggesting its potential application for environmental monitoring.

Heo, Ji Won published the artcilePreparation of amine-functionalized lignins for the selective adsorption of Methylene blue and Congo red, SDS of cas: 13822-56-5, the publication is Chemosphere (2022), 133815, database is CAplus and MEDLINE.

Research on low-cost bio-adsorbents for the removal of harmful substances from effluents has recently attracted significant attention. In this study, three types of amino-silane-modified lignins (ASLs) with primary, secondary, and tertiary amine groups were prepared, and their adsorption behavior toward cationic and anionic dyes was investigated. Chem. structural analyses indicated that the three amino-silane reagents resulted in different mol. self-assembly structures on the lignin surface. The ASLs exhibited enhanced thermal stabilities and increased surface areas with different surface charges in different pH ranges. Owing to the high d. of primary, secondary, and tertiary amine groups, the ASLs exhibited excellent adsorption capacities for cationic and anionic dyes. Addnl., they selectively adsorb anionic and cationic dyes according to the pH conditions. The ASL with primary amine had the highest adsorption capacity for Methylene blue and Congo red, reaching 187.27 and 293.26 mg·g^-1, resp., followed by ASLs with the secondary amine and tertiary amine. All adsorption processes followed the Langmuir and Temkin isotherms and had pseudo-second-order kinetics. The hypothesized adsorption mechanism mainly involves electrostatic interaction, NH-π interaction, hydrogen bonding interaction and π-π interaction.

Trisunaryanti, Wega published the artcileEffective production of biofuel from used cooking oil over Ni-Pd loaded on amine-functionalized Lapindo Mud catalyst, Recommanded Product: 3-(Trimethoxysilyl)propan-1-amine, the publication is Reaction Kinetics, Mechanisms and Catalysis (2022), 135(2), 951-970, database is CAplus.

In the present work, Lapindo Mud (LL) as natural-based catalyst support material without any prior chem. extraction obtained from Sidoarjo, East Java comprising SiO₂ (45.49%), Al₂O₃ (13.82%), and Fe₂O₃ (21.63%) was impregnated with the combination of Ni and/or Pd metal catalyst (i.e. LL, Ni/LL, Pd/LL, Ni-Pd/LL). The modification of heterogeneous catalyst (catalyst-support material) by the addition of amine-functionalized group from 3-APTMS compound (i.e. NH₂/LL, Ni-NH₂/LL, Pd-NH₂/LL, and Ni-Pd-NH2/LL) to improve catalyst activity and selectivity towards Free Fatty Acid (FFA) in the hydro-treatment process of used cooking oil into biofuel was thoroughly compared. The result found that Ni-Pd-NH₂/LL catalyst was able to generate the higher conversion of liquid product and to decrease the generation of FFA from 10.1 to 3.2% compared to the un-grafted Ni-Pd/LL catalyst. The study showed that the optimum temperature to produce hydrocarbons in hydro-treatment process using Ni-Pd-NH₂/LL catalyst was at 550°C with 1/100 catalyst-to-feed weight ratio.

Benzaoui, Karim published the artcileElectromagnetic interference shielding effectiveness of polypyrrole-silver nanocomposite films on silane-modified flexible sheet, HPLC of Formula: 13822-56-5, the publication is High Performance Polymers (2022), 34(3), 310-320, database is CAplus.

The conventional electromagnetic interference (EMI) shielding materials are being gradually replaced by a new generation of supported conducting polymer composites (CPC) films due to their many advantages. This work presents a contribution on the effects of silane surface-modified flexible polypyrrole-silver nanocomposite films on the electromagnetic interference shielding effectiveness (EMI-SE). Thus, the UV-polymerization was used to in-situ deposit the PPy-Ag on the biaxial oriented polyethylene terephthalate (BOPET) flexible substrates whose surfaces were treated by 3-aminopropyltrimethoxysilane (APTMS). XPS analyzes confirmed the APTMS grafting procedure. Structural, morphol., thermal, and elec. characteristics of the prepared films were correlated to the effect of substrate surface treatment. Thereafter, EMI-SE measurements of the elaborated films were carried out as per ASTM D4935 standard for a wide frequency band extending from 50 MHz to 18 GHz. The obtained results confirmed that the APTMS-treated BOPET film exhibit higher EMI shielding performance and better elec. characteristics compared to the untreated film. In fact, a 32% enhancement of EMI-SE was noted for the treated films compared to the untreated ones. Overall, these results put forward the role played by the surface treatment in strengthening the position of flexible PPy-Ag supported films as high-performance materials in electronic devices and electromagnetic interference shielding applications.

Danil de Namor, A. F. published the artcileAmine-modified silica for removing aspirin from water, Recommanded Product: 3-(Trimethoxysilyl)propan-1-amine, the publication is International Journal of Environmental Science and Technology (2022), 19(5), 4143-4152, database is CAplus.

Abstract: The synthesis and structural characterization (Fourier transform IR, FTIR spectrometry, SEM, SEM and energy-dispersive X-ray, EDX) of amino-modified silicates (unloaded L1, and aspirin-loaded, L2) are reported. The optimal conditions for the extraction of aspirin from water by the modified silicate material were determined as a function of the mass of the extracting agent and the pH of the aqueous solution The optimum mass was found to be 0.08-0.10 g with 99.9% removal of aspirin. Maximum extraction of aspirin by the material was observed at pH 4. The kinetics, the removal capacity of the material, as well as its recycling, were investigated. The results indicate that (i) the process is fast and (ii) the removal capacity for the drug is greater than that of previously reported materials and (iii)the modified silicate can be easily recycled. These data along with the low cost involved in the production of the material led to the conclusion that the modified silicate has the required potential for industrial use. Mol. simulation calculations suggest that one unit of aspirin interacts with one unit of the modified silicate L1 through hydrogen bond formation between the amine functional group of the silicate and the oxygen donor atoms of aspirin. Final conclusions are given.
