Yoon, Ki-Yong published the artcileUnveiling role of Ti dopant and viable Si doping of hematite for practically efficient solar water splitting, Product Details of C6H17NO3Si, the publication is ACS Catalysis (2022), 12(9), 5112-5122, database is CAplus.

Doping engineering is of key importance for controlling the elec., optical, and structural properties of a semiconductor. In more expanded doping systems, codoping with deep insight and understanding of interactions between impurities is necessary to make an efficient photoelectrode. Here, we show that the high formation energy of a Si-doped hematite can be decreased with the introduction of a host Ti-dopant, making easy and cost-efficient solution-based Si doping possible. The effect of the pos. interaction between dopants lowers the formation energy in a standard atm. to the one under extreme conditions of about 10^-10 atm. By taking advantage of formation energy control, we achieved a photocurrent d. of 4.3 mA cm^-2 at 1.23 V_RHE in the optimized Si:Ti codoped hematite with a cocatalyst without using any demanding exptl. processes. Our study suggests a ground rule for the facile incorporation of the high-formation-energy dopant into photocatalysts, which can be readily extended to other doped systems to achieve a substantial improvement in PEC performance.

Yousatit, Satit published the artcileSelective synthesis of 5-hydroxymethylfurfural over natural rubber-derived carbon/silica nanocomposites with acid-base bifunctionality, Name: 3-(Trimethoxysilyl)propan-1-amine, the publication is Fuel (2022), 122577, database is CAplus.

5-Hydroxymethylfurfural (HMF) is an important platform mol., derived from biomass-based carbohydrates, for the production of renewable fuel additives, liquid hydrocarbon fuels, biopolymers, and specialty chems. In this study, a mesoporous carbon/silica (MCS) nanocomposite, as catalyst support, was prepared using a nanocomposite of natural rubber (NR) and hexagonal mesoporous silica (HMS) as a precursor. To obtain a series of acidic, basic, and bifunctional acid-base catalysts, the MCS surface was modified using post-synthesis methods in which the carbon moieties were decorated with sulfonic acid groups, whereas the silica matrix surface was grafted with 3-aminopropyl groups. The resulting materials exhibited high surface area, large pore volume, and contain some oxygen-containing functional groups. Their acid-base properties were tunable by varying the content of sulfonic acid and aminopropyl groups. The HMF was synthesized by catalytic conversion of fructose and glucose in a biphasic medium. Fructose dehydration catalyzed by sulfonated MCS catalyst (MCS-SO₃H) at 150¡ãC for 2 h yields 56% HMF at 81% conversion. For the glucose system, the Bronsted basic sites facilitated the glucose-fructose isomerization, however, it promoted the formation of undesired humins. The acid/base ratio of bifunctional MCS catalysts (MCS-SO₃H-NH₂) contributes to the HMF yield and selectivity. The HMF yield of 39.4% was obtained over the MCS-SO₃H-NH₂ catalyst with an acid/base ratio of 0.10 at 190¡ãC for 1 h. In both systems, the formation of levulinic acid, a byproduct of HMF hydrolysis, was suppressed due to the hydrophobicity of the MCS catalyst. These developed catalysts are promising for the synthesis of HMF from glucose, at high substrate concentration than those reported in the literature.

Maia, Marcella T. published the artcileSilica Nanoparticles and Surface Silanization for the Fabrication of Water-Repellent Cotton Fibers, HPLC of Formula: 13822-56-5, the publication is ACS Applied Nano Materials (2022), 5(4), 4634-4647, database is CAplus.

Water-repellent and anticorrosive superhydrophobic cotton fabrics were produced via an eco-friendly water-based coating with core-shell fluorescent silica nanoparticles (SiPs) and subsequent immersion in a mixture of two fluorine-free organosilanes (3-(aminopropyl)trimethoxysilane and trimethoxy(octadecyl)silane). Transmission electron microscopy confirmed the spherical and core-shell structure of SiPs, and Fourier-transform IR spectroscopy characterized their chem. composition SEM with energy-dispersive X-ray spectroscopy confirmed the high coating coverage even after realistic laundering cycles. In confocal laser scanning microscopy, the fluorescent core-shell SiPs were used as probes to characterize the coating coverage on the surface of the cotton fibers. The high fluorescent signal provided by the fluorescent core-shell SiP cores enabled their visualization over large surface areas of the modified cotton fibers, before and after several washing cycles. The hydrophobic property of the cotton fiber treatments was evaluated considering the type of particle coating (monolayer or hierarchization), covalent bond with silanes, and a final curing process. Monolayer coating with fluorescent core-shell SiPs and further silanization yielded cotton fibers with high hydrophobicity and excellent durability (tested up to 10 washing processes), maintaining water contact angle (WCA) values above 150¡ã, repellency grade 3, and lower water uptake (165%) compared to pristine (600%) or silanized cotton fibers (340%). Principal component anal. showed that the silanization process increased the SiP-coated cotton fiber resistance to laundering sustaining nonwetting properties up to 10 washing cycles, which was not observed for SiP-coated fibers subjected to no silanization process. Addnl., the silanized and noncured SiP-coated fibers were tested against solvents and corrosive aqueous media, for which high resistance to toluene, chloroform, and strong acid was observed, with the maintenance of static and dynamic WCAs. Thus, this systematic study allowed us to verify the main factors associated with superior hydrophobicity and durability and achieve an optimized and less toxic approach that combines the deposition of fluorescent core-shell SiPs and binary silanization.

Niihara, Ken-ichi published the artcileCellulose nanofibril/polypropylene composites prepared under elastic kneading conditions, Recommanded Product: 3-(Trimethoxysilyl)propan-1-amine, the publication is Cellulose (Dordrecht, Netherlands) (2022), 29(9), 4993-5006, database is CAplus.

An aqueous dispersion of 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-oxidized cellulose nanofibrils (TEMPO-CNFs) was mixed with diethylene glycol (DEG) and dodecyltrimethylammonium chloride (DTMACl) with or without silane coupling agents. The mixture was heated at 40 ¡ãC for 1 d to prepare an oven-dried TEMPO-CNF/DEG/DTMACl, which was added to maleic anhydride-modified polypropylene (MA-PP) and kneaded at 165-175 ¡ãC with high shear forces to prepare TEMPO-CNF/MA-PP master batches. Various amounts of TEMPO-CNF/MA-PP master batch pieces were mixed with PP to prepare TEMPO-CNF/MA-PP/PP composite sheets. The yield stress and storage modulus at 25 ¡ãC of the composite sheets increased almost linearly with an increase in TEMPO-CNF content. However, the elongation at break decreased clearly with TEMPO-CNF content because of partial formation of TEMPO-CNF aggregates in the composites. The presence of TEMPO-CNFs restricted flow behavior of the MA-PP/PP components above 160 ¡ãC, although the crystallinities and melting behavior of MA-PP/PP in the composite sheets at ? 160 ¡ãC were unchanged. The apparent aspect ratios of TEMPO-CNF components in the composite sheets were 5-13 by partial aggregation of TEMPO-CNFs in the PP matrix, although the aspect ratio of the original TEMPO-CNFs dispersed in water was ? 183. The aggregation behavior of TEMPO-CNFs in the PP matrix may have resulted in brittle tensile properties of the composite sheets. The TEMPO-CNF-containing PP sheets have better printability and adhesion performance between sheets using glues. These results indicate that the oven-dried TEMPO-CNFs can be used as fillers for improvement of mech., thermal, and printing properties of recycled and low-quality PP and for quant. expansion of recycled PP.

Poly(N-isopropylacrylamide)-spiropyran (PNIPAAm-SP) copolymers were tethered onto the glass substrate using surface-initiated atom transfer radical polymerization (SI-ATRP). The substrate was previously activated by ultra-violet ozone (UVO) irradiation and the pre-synthesized initiator was immobilized on it. A block of PNIPAAm was grafted onto the glass substrates, followed by a second block of mixed NIPAAm and spiropyran acrylate (SPA). The effects of UVO irradiation time and polymerization time of spiropyran containing block on cell sheet formation and detachment characteristics were evaluated. The photo-responsiveness of SPA was evaluated by ultra-violet visible spectroscopy (UV-vis). The presence and thickness of the grafted polymer layers were evidenced by attenuated total reflectance Fourier-transform IR spectroscopy (ATR-FTIR), XPS and field emission SEM (FE-SEM). The results of water contact angle (WCA) anal. showed that the modified surfaces became hydrophilic with decreasing temperature from 37 to 20 ¡ãC as well as with light irradiation L929 mouse fibroblast cell culture results indicated a complete cell sheet formation. By applying temperature or light stimuli, the cell sheets were detached in a trypsin-free procedure.

Al-Wasidi, Asma S. published the artcileModification of Silica Nanoparticles with 4,6-Diacetylresorcinol as a Novel Composite for the Efficient Removal of Pb(II), Cu(II), Co(II), and Ni(II) Ions from Aqueous Media, HPLC of Formula: 13822-56-5, the publication is Journal of Inorganic and Organometallic Polymers and Materials (2022), 32(6), 2332-2344, database is CAplus.

Due to the danger of heavy metals such as Pb(II), Cu(II), Co(II), and Ni(II) ions to the environment and humans, the world needs to develop new effective adsorbents to get rid of them. Many Schiff bases can form chelates with most heavy metal ions. Hence, loading them on supports like silicon oxide as new composites help to solve the pollution problem. So, in this work, a new composite based on the formation of Schiff base on silica nanoparticles was facilely synthesized. (3-aminopropyl)trimethoxysilane was used to modify silica nanoparticles with silanol groups (Si-OH). Then, the modified silica was then combined with 4,6-diacetylresorcinol to create a new Schiff base/silica composite. XRD, FE-SEM, FT-IR, CHN analyzer, and N2 adsorption/desorption analyzer were used to characterize the synthesized composite. The formation of the Schiff base results in a significant drop in the intensity of the composite XRD peak at 2 = 21.9¡ã. In addition, the FT-IR bands at 3443 and 1606 cm-1 are due to the stretching and bending vibrations of OH and/or C=N, resp. The FE-SEM images confirmed that the silica has uneven forms while the composite has a flaky surface due to the formation of the Schiff base. According to an elemental anal. of the composite, the percentages of C, H, and N are 15.26, 3.24, and 1.65%, resp. The produced Schiff base restricts the pores of silica and hence the composite BET surface area and total pore volume were lowered. The synthesized composite was used to remove Pb(II), Cu(II), Co(II), and Ni(II) ions from aqueous solutions with high efficiency. The maximum uptake capacity of the composite toward Pb(II), Cu(II), Co(II), or Ni(II) ions is 107.066, 89.767, 80.580, and 70.972 mg/g, resp. The adsorption processes of the investigated metal ions were chem., spontaneous, and well fitted with the Langmuir equilibrium isotherm and pseudo-second-order kinetic model. The synthesized composite can be successfully regenerated and utilized various times in the removal of investigated metal ions from aqueous solutions

Siloxane bearing benzoxazines from renewable phenolics such as vanillin and coumarin were prepared and reacted with glycerol by silyl ether exchange reactions to yield processable, soft, and curable bio-hybrid gels. Moreover, these benzoxazine-based gels were cured below 200¡ãC favored by the catalytic effect of hydroxyl groups present on glycerol moieties to yield bio-hybrid polybenzoxazines. All the synthesized intermediates, gels, and ultimate networks were characterized by ¹H, ¹³C NMR, FTIR, and UV-Vis analyses. The curing behavior and thermal stabilities of the monomers, glycerol-based gels and related polybenzoxazines were investigated by differential scanning calorimeter (DSC) and thermogravimetric anal. (TGA). Moreover, the activation energies of polymerization of benzoxazine monomers were determined by DSC using the Kissinger and Ozawa methods.

The new catalyst copper defines as Fe₃O₄@Pectin@(CH₂)₃-Acetamide-Cu(II) was successfully manufactured and fully characterized by different techniques, including FT-IR, XRD, TEM, FESEM, EDX, VSM, TGA and ICP anal. All results showed that copper was successfully supported on the polymer-coated magnetic nanoparticles. One of the most important properties of a catalyst was the ability to be prepared from simple materials such as pectin that’s a biopolymer that was widely found in nature. The catalytic activity of Fe₃O₄@Pectin@(CH₂)₃-Acetamide-Cu(II) was examined to obtain triazoles I [R¹ = Bn, 4-MeC₆H₄CH₂, CH₂C(O)C₆H₅, etc.; R² = CH₂OH, (Me)₂C(OH), Ph] in a classical, one pot and the three-component reaction of terminal alkynes, alkyl halides and sodium azide in water and observed, proceeding smoothly and completed in good yields and high regioselectivity. The critical potential interests of the present method include high yields, recyclability of catalyst, easy workup, using an eco-friendly solvent and the ability to sustain a variety of functional groups, which give economical as well as ecol. rewards.

Yang, Kaixiang published the artcileDeep eutectic solvent based adhesive with dynamic adhesion, water-resistant and NIR-responsive retrieval properties, Recommanded Product: 3-(Trimethoxysilyl)propan-1-amine, the publication is Chemical Engineering Journal (Amsterdam, Netherlands) (2022), 135646, database is CAplus.

Adhesives that exhibited dynamic adhesion in underwater environments are of great importance. Here, we report a simple yet versatile method to fabricate underwater adhesive with time-dependent dynamic adhesion derived from the silane-based polymerized deep eutectic solvent (PDES). Particularly, the incorporation of silane can endow the underwater adhesive with a time-dependent adhesive performance, i.e., the adhesion strength increased at first and then decreased. With the further introduction of MXene, NIR-controlled retrieval property can be achieved. We anticipate that the alternative strategy presented here will open a new avenue for designing high-performance underwater adhesive materials with tunable and synergistic properties.

This work reports the preparation and characterization of mixed matrix membranes (MMMs) based on mesoporous ordered COK-12 silica modified with 3-aminopropyltrimethoxysilane as filler, and a series of polybenzimidazoles with different main-chain structure as polymer matrix. Polybenzimidazoles (PBIs) were prepared from 3,3′-diaminobenzidine and several dicarboxylic acids with different chem. structure. The physicochem. studies, as well as thermal, structural, and morphol. properties of MMMs were determined by Fourier transform IR spectroscopy, thermogravimetric anal., X-ray diffraction (XRD), and SEM. In addition, gas permeability properties of MMMs were tested by using a gas mixture of CO₂/CH₄ at different upstream pressures. Results indicated that thermal stability of PBI above 400¡ãC is kept even after the addition of the modified COK-12 silica. The d-spacing of the PBI membranes determined by XRD was slightly increased with the addition of the modified COK-12 silica particles. The permeability tests carried out at operating pressures of 50 and 150 psi showed that the addition of amino-modified COK-12 silica particles improved significantly the CO₂ permeability of MMMs with respect to the pristine PBI. At the same time, the selectivity values were also enhanced, which in some cases were found to be more than double compared to the resp. pristine membrane. The contribution of the modified COK-12 silica on the gas transport properties was more promising in MMMs comprising PBIs with less rigid backbone chem. structure.
