Sadrara, Mina published the artcileFabrication of highly mesoporous ZSM-48 zeolite by anionic surfactant-organosilane system for catalytic conversion of methanol to gasoline, Category: catalysis-chemistry, the publication is Solid State Sciences (2022), 106888, database is CAplus.

A highly mesoporous ZSM-48 zeolite has been prepared using low-cost anionic surfactant sodium dodecylsulfate (SDS) as mesopore-generating agent and short-chain 3-aminopropyltrimethoxysilane (APTMS) as co-structure directing agent. The mesoporosity formation took place through the interaction between the silica species/APTMS and SDS mols. existing in the gel composition In the synthesis solution with a pH slightly less than ten, the methoxysilyl moiety in APTMS was hydrolyzed to the -SiO3 units and became incorporated inside the zeolite crystals while the pos. charged ammonium site of APTMS interacted with the neg. charged head group of the SDS. Aggregation of aluminosilicate/APTMS species around the SDS micelles during the crystallization process, led to the formation of a mesoporous zeolite. In this study, a conventional ZSM-48 and seven ZSM-48 zeolites from different mixtures containing SDS, APTMS and SDS-APTMS with different APTMS/SiO2 molar ratios were synthesized. Changes in the properties of the synthesized samples were investigated by XRD, FTIR, SEM, TEM, nitrogen adsorption/desorption isotherms, NH3-TPD and TGA. The optimum ZSM-48/Sur/0.008OS zeolite prepared with APTMS/SiO2 molar ratio of 0.008 exhibited both bundled needle-like and spherical morphologies. The catalytic conversion of methanol to gasoline (MTG) was evaluated in a fixed-bed reactor, and the results revealed that mesoporosity development using Sur-OS system enhanced catalytic activity of ZSM-48/Sur/0.008OS catalyst compared to the other sample. The optimum zeolite showed long stable phase of 40 h and liquid hydrocarbon yield of 42% was achieved for 100% methanol conversion in 22 h of reaction. The proposed method opens a new and simple route for the synthesis of hierarchically porous ZSM-48 with tunable porosity using low-cost anionic surfactants.

Singh, Amravati S. published the artcileHighly regioselective tandem hydroformylation of substituted styrene using Iminophosphine rhodium complex immobilized on carbon, Recommanded Product: 3-(Trimethoxysilyl)propan-1-amine, the publication is Journal of Industrial and Engineering Chemistry (Amsterdam, Netherlands) (2022), 218-232, database is CAplus.

Reported the sustainable route for the synthesis of ionic carbon from bio-derived sugarcane-waste (Bagasse) and further anchoring with iminophosphine rhodium complex (Rh@BCNP) and utilized for tandem hydroformylation reaction. The SEM anal. confirmed the formation of spherical shape morphol. of carbon with sizes ranging from 30-150 nm. The successful functionalization of the iminophosphine rhodium complex on the carbon surface were determined by XPS, TEM, FE-SEM, ³¹P NMR, ¹³C CP-MAS-NMR and FTIR anal. Furthermore, ICP-OES anal. confirmed the presence of 0.307 mmoles/g of Rh and 0.484 mmoles/g of P on the carbon surface. Rh@BCNP catalyst was the best combination of triphenylphosphine ligand, imine and rhodium metal, resulting in hybrid material with some acidic properties of carbon that favor the selectivity towards linear products. Rh@BCNP showed remarkable catalytic performance under moderate reaction conditions (80¡ãC, 40 bar (CO + H₂)) in 5 h. This sharp divergence from other methods leading to linear amines and acetals results in a novel atom economic approach to synthesize pharmaceuticals and industrial products. The Rh@BCNP catalyst gave recyclability up to five cycles.

Poly(lactic acid) (PLA), one of the most promising biodegradable polymer products, has achieved wide applications for its relatively good mech. properties and moderate degradability. Here we report an environment-friendly filler, the organic-inorganic composite Janus nanosheets (PLA/PBS JNs), which can jam at the interface of the PLA/PBS blend with a low threshold as the compatibilizer and can simultaneously toughen the composites and improve the gas barrier performance due to better interfacial interaction and tortuous path effect. With 0.3 weight % of PLA/PBS JNs added, the tensile strength and elongation at break of the PLA/PBS blend can be improved by 37% and 224%, resp. After a further hot-pressing process, the barrier performance of the PLA/PBS composite membranes can be significantly enhanced since PLA, PLA/PBS JNs, and PBS are arranged in a nearly lamellar structure with oxygen permeability of 0.63 ¡Á 10^-15 cm³ cm¡¤cm^-2 s^-1 Pa^-1 with only 0.5 weight % of PLA/PBS JNs.

Silviana, S. published the artcileSynthesis of Aminopropyl-Functionalized Mesoporous Silica Derived from Geothermal Silica for an Effective Slow-Release Urea Carrier, Formula: C6H17NO3Si, the publication is Industrial & Engineering Chemistry Research (2022), 61(26), 9283-9299, database is CAplus.

An effective method to prepare slow-release urea was developed with aminopropyl-functionalized mesoporous silica (MS) to achieve enhanced urea adsorption and slow-release properties. As a novel study, mesoporous silica was developed using treated geothermal silica as the silica source, cetyltrimethylammonium bromide (CTAB) as the surfactant, and 3-aminopropyl trimethoxy silane (APTMS) as the surface modification agent. Mesoporous silica with the most desirable properties of uniform micromorphol. containing 38.55 wt % silica particles, 668.849 m²/g surface area, 149.33-353.28 mL/g adsorption-desorption range, and 0.26 mL/g adsorption pore volume was achieved using 0.05 mol of CTAB. The synthesized mesoporous silica showed type-IV hysteresis, which corresponds to mesoporous materials. Differential scanning calorimetry (DSC)-thermogravimetric anal. (TGA) thermograms showed that mesoporous silica is more reactive, with peaks at 82.3 and 159.5 ¡ãC, has good thermal stability, and undergoes only 17.61% weight loss until 124 ¡ãC. SEM (SEM) showed that functionalization and urea adsorption to mesoporous silica resulted in no significant morphol. changes. In the Fourier transform IR (FTIR) spectra, MS/APTMS/U26.74 was observed to have higher intensities of C=O, N-H, C-N, and C-H groups compared with other samples. The cumulative urea release during 7 days was 184.5 ppm (92.4%) for com. urea and 124.6 ppm (64.4%) for MS/APTMS/U26.74. The Higuchi kinetic model yielded the best fit predicting MS/APTMS/U26.74 release kinetics, with an R² of 0.9979 and a Higuchi constant of 24.4964%/day. Finally, MS/APTMS/U26.74 synthesized using geothermal silica, CTAB, and APTMS was noted to possess a potential composition for slow-release urea with enhanced efficiency.

Sivaperumal, R. published the artcileStudy of fiber delamination on silane modified ramie fiber/ OMMT nano-clay epoxy composite under low-velocity impact, shear load, and high-speed drilling, Related Products of catalysis-chemistry, the publication is Polymer Composites (2022), 43(7), 4280-4287, database is CAplus.

In this present study, the effect of silane treated ramie fiber addition along with organically-modified montmorillonite (OMMT) nano clay in epoxy resin composite was investigated in drop load impact, shear loading, and high-speed drilling. The main aim of this research study was to develop a high-laminar shear strength epoxy structural composite for various engineering applications. To improve the laminar adhesion the fiber was treated using silane via acid hydrolysis technique. The OMMT nanoclay also added with fiber in order to improve the load bearing effect and adhesion phenomenon. The composites were prepared using hand layup method with postcuring. The adhesion behavior of composites was tested based on American society for testing and materials standards and compared. According to the results, the treated ramie fiber possesses high resistance to impact loading. The ballistic resistance of composite is increased three fold when compare with as-received fiber-epoxy composites. The interlaminar shear strength of composite designation C1.5 gives highest shear strength of 35 MPa. The drilling study revealed highest dimensional stability for treated fiber. No fiber chip off and pull out at the drilled hole surface. The fractog. anal. confirms no lamina delamination occurs even at high-speed drilling. These delamination resistance epoxy-based composites are suitable in automobile, structural and defense gadget manufacturing applications.

Jodeh, Shehdeh published the artcileExperimental and theoretical study for removal of trimethoprim from wastewater using organically modified silica with pyrazole-3-carbaldehyde bridged to copper ions, Quality Control of 13822-56-5, the publication is BMC Chemistry (2022), 16(1), 17, database is CAplus and MEDLINE.

SiNP-Cu, a chelating matrix, was produced by delaying and slowing 1.5-dimethyl-1H-pyrazole-3-carbaldehyde on silica gel from functionalized with 3-aminopropyltrimethoxysilane. The prepared sorbent material was characterized using several techniques including BET surface area, FT-IR spectroscopy, SEM (SEM), thermogravimetric anal. (TGA), and nitrogen adsorption-desorption isotherm. The pseudo-second-order model provided the best correlation due to the big match between the exptl. and theor. of different adsorption coefficients The Langmuir and Freundlich adsorption models were used and the study showed a better match with the Freundlich model with a capacity of removal reached up to 420 mg g^-1. The removal capacity was dependent on pH and increased by increasing pH. The removal percentage reached 91;5% at pH = 8. The adsorbent demonstrated a high percentage removal of TMP, reaching more than 94% when increased pH. The sample was simply regenerated by soaking it for a few minutes in 1 N HCl and drying it. The sorbent was repeated five times with no discernible decrease in removal capacity. The thermodn. study also showed endothermic, increasing randomness and not spontaneous. The free energy was 2.71 kJ/mol at 320 K. The findings of the DFT B3LYP/6-31 + g (d, p) local reactivity descriptors revealed that nitrogen atoms and ¦Ð-electrons of the benzene and pyrimidine rings in the TMP are responsible for the adsorption process with the SiNP surface. The neg. values of the adsorption energies obtained by mol. dynamic simulation indicated the spontaneity of the adsorption process. The global reactivity indexes prove that TMP is stable and it can be removed from wastewater using SiNP surface. The results of the local reactivity indexes concluded that the active centers for the adsorption process are the nitrogen atoms and the ¦Ð-electrons of the pyrimidine and benzene rings. Furthermore, the pos. value of the maximum charge transfer number (¦¤N) proves that TMP has a great tendency to donate electrons to SiNP surface during the process of adsorption.

Kaya, Dogan published the artcileMagnetically separable low Pt substituted Co nanoparticles: Investigation of structural, magnetic, and catalytic properties, Computed Properties of 13822-56-5, the publication is Physica B: Condensed Matter (Amsterdam, Netherlands) (2022), 413765, database is CAplus.

Developing multifunctional nanoparticles (NPs) for magnetic and catalytic purposes is crucial for controlling magnetic properties and reducing production costs. We synthesized Co and low Pt loaded CoPt NPs by the modified polyol process. Co and CoPt NPs exhibited coexist fcc and hcp phases which are confirmed with x-ray diffraction and Rietveld refinement anal. SEM images revealed the average size of the NPs smaller than 9 nm with a narrow distribution. An irreversible magnetization-temperature behavior of the particles is observed in the modes of zero-field cooled and field cooled with a strong ferromagnetic signal close to 350 K. The field-dependent magnetization up to ¡À5 T was investigated to determine coercive field (H_c), exchange bias (H_E), saturation magnetization (M_s), remanent magnetization (M_r), and the ratio of remanent magnetization to saturation magnetization (M_r/M_s). There is a general decrease in magnetic values due to an increase of both the temperature and the Pt ratio in Co nanoparticles. When the Pt/Co ratio drops to 1%, the sample was measured with the highest H_c value of 648.5 Oe and M_s value of 100 emu/g at 5 K. On the contrary, increasing the concentration of Pt to 10% resulted in a reduction for the M_s value below 40 emu/g. Besides, cyclic voltammetry measurements showed apparent hydrogen reduction in the potential range of -0.91 V and -0.96 V (vs Ag/AgCl) and 10% Pt loaded CoPt NPs exhibits the highest activity after 10th cycles and increase the activity up to 15.80 mA cm^-2 at -1.2 V due to the surfactant.

Talite, Maria Jessabel published the artcilePerylene Tetracarboxylic Acid Crosslinked to Silica Matrix that Enables Ultrahigh Solid-State Quantum Yield and Efficient Photon Recycling for Holographic Luminescent Solar Concentrators, Related Products of catalysis-chemistry, the publication is Solar RRL (2022), 6(4), 2100955, database is CAplus.

Perylene derivatives possess large absorptivity and high quantum yields (QYs) and thus are promising luminophores for luminescent solar concentrators (LSCs). Unfortunately, severe aggregation-caused quenching, poor solubility, and large reabsorption significantly reduce their solid-state photoluminescence. To address these issues, perylene tetracarboxylic acid (PTCA) is prepared by hydrolyzing perylene tetracarboxylic dianhydride in sodium hydroxide, which is highly compatible with amino-silane precursors for in situ sol-gel synthesis of the silica matrix. In this case, highly luminescent and transparent PTCA@silica composites are formed, in which PTCA mainly exists in the monomer species due to covalent crosslinking to silica network structures. Therefore, a near-unity solid-state QY of ¡Ö90% is obtained even at elevated loadings and existence of reabsorption due to the preservation of monomer states and efficient photon recycling. To demonstrate their potentials in LSCs, large-area LSCs (10 cmx10 cmx0.5 cm) with laminated configuration are fabricated, yielding a high power conversion efficiency of 1.1%. To mitigate the escape-cone losses, the LSCs can be integrated with holog. grating, reaching an ultrahigh edge-emission efficiency of 90%.

Eisner, Ludmila published the artcileDoped silica sol layer coatings on evanescent field fiber Bragg gratings for optical detection of nitroaromate based explosives, Product Details of C6H17NO3Si, the publication is Sensors and Actuators, A: Physical (2022), 113687, database is CAplus.

Evanescent field etched fiber Bragg gratings (eFBG) were prepared with doped and non-doped nanoporous silica sol coatings for optical detection of the nitroarom. explosives 2,4-dinitrotoluene (DNT), 1,3-dinitrobenzene (DNB) and trinitrotoluene (TNT). We used 3-aminopropyltrimethoxysilane (APTMS) and tetrabutylammonium hydroxide based receptors (TBAH, C16H37NO) as dopants in order to increase the specific identification of the nitroaromates. In nitroarom. trace gas atm. the induced wavelength shift of the Bragg reflection signal was highest for the sensor with TBAH-doped silica sol receptor coating. Within the first two minutes during exposure the change of the signal intensity, reflecting the adsorption dynamics of the nitroarom. explosives, was most significant and characteristically depending on the type of receptor dopant used. The cross sensitivities of the sensor with TBAH-doped silica sol receptor coating with four common solvents like acetone, ethanol, 2-propanol and THF (THF) in comparison to the sensitivity of the tested explosives was more than six orders of magnitude (106) lower than that of solvents, indicating a very high selectivity of the sensor. By applying a simplified diffusion model correlated to a series of measurements with different distances to the target we estimated the limit of detection for a sensor coated with TBAH doped silica sol with 35.8 ¡À 0.9 ppb for DNB and 140.2 ¡À 1.8 ppb for DNT in air at room temperature Using a more etched FBG (but mech. less robust) sensor we were able to detect TNT as well at concentrations about 5 ppb at room temperature in air. A major result of our investigations was to demonstrate, that the nanoporous silica sol host matrix is suited for fast adapting with low technol. effort the affinity of the receptor coating for silica-based evanescent field sensors. For future applications a set of sensors of silica-sol coatings with different dopants in combination with pattern recognition of the sensor signals could be used for clear identification of explosives.
