Tang, Mei published the artcileEngineering design of graphene tightly wrapped hollow structure for boosted lithium storage in conversion/alloying electrode: A case of SnO₂, Application of 3-(Trimethoxysilyl)propan-1-amine, the publication is Scripta Materialia (2022), 114649, database is CAplus.

Developing cost-effective and high-performance conversion/alloying anode materials in lithium-ion batteries (LIBs) depend on the exquisite design of nanostructure that can efficiently improve volume change and enhance lithium storage capability of active materials. Herein, taking the typical SnO₂ as an example, a universal strategy has been proposed to solve many difficulties faced by these electrode materials, i.e. in situ encapsulating hollow SnO₂ nanospheres into sack-like reduced oxide graphene nanosheets (SnO₂@RGO). This simple and ingenious design combines the flexibility of external graphene and the hollow characteristics of internal SnO₂, thus providing more insertion sites and greatly avoiding the occurrence of structural collapse caused by large volume changes upon cycling. As expected, the SnO₂@RGO electrode shows a larger initial discharge capacity, better capacity retention and more remarkable rate capability as compared to pristine SnO₂ nanospheres electrode when used as advanced anode for LIBs.

M, Vinothkumar published the artcileSilane Grafted Cellulose and Biosilica Toughened Glass-Epoxy Composite: Mechanical, Hydrophobicity and Low Velocity Impact Behavior, Product Details of C6H17NO3Si, the publication is Silicon (2022), 14(7), 3601-3613, database is CAplus.

High toughness, impact damage resistance biocompatible glass-epoxy composites were prepared using 3-Aminopropyltrimethoxysilane (APTMS) treated cellulose and biosilica nanoparticle and evaluated for their tensile, flexural, impact, wear and water absorption behavior. The main aim of this present investigation was to improve the strength characteristics and load-bearing effect of glass-epoxy composite using biocompatible fillers and how the surface modification process helps in the improvement of the properties. The cellulose and biosilica particle was surface-treated using (APTMS) via wet solution method. Similarly, the glass-epoxy composites were prepared via the hand layup method followed by room temperature curing. The results revealed that the addition of cellulose particle into the glass-epoxy composite improved the toughness and energy absorption. However, the subsequent addition of biosilica particle improved the mech., wear and drop load impact toughness by about 200-300%. It is noted that in all composites the silane treated reinforcements gives improved results of a min. of 20-50%. The hydrophobicity of composites retained with higher contact angle for silane treated reinforcements in epoxy resin composite. The scanning electron microscopic images revealed uniform dispersion and improved adhesion with matrix for silane treated reinforcements.

Ma, Ronghua published the artcileConstructing discontinuous silicon-island structure with low surface energy based on the responsiveness of hydrophilic layers to improve the anti-fouling property of membranes, Computed Properties of 13822-56-5, the publication is Journal of Membrane Science (2022), 120770, database is CAplus.

In recent years, membrane separation technol. has been widely used in various fields. And for the increasingly severe oily wastewater system, there is an increasing demand for the anti-fouling properties of the membranes. Based on the concept of fluorine-free, non-toxic, environmental-friendly and low-cost, this study constructed a discontinuous silicon-island structure with low surface energy on the surface of the hydrophilic membrane, which endows the PVDF-CTFE membrane with fouling resistance and cleaning pH-responsiveness. The discontinuous silicon-island structures were constructed by introducing SiO₂ nanoparticles on the super-hydrophilic layer of the PVDF-CTFE membrane modified by itaconic acid, and then hydrophobically treated with polydimethylsiloxane (PDMS). The exptl. results exhibited that the modified membrane reached the hydrophobic and underwater super-oleophobic state when treated by PDMS for 1.0 h. The water contact angle (WCA) and the underwater oil contact angle (OCA) were 124¡ã and 151¡ã, resp. Furthermore, the water flux remained at 186 L m^-2 h^-1 with no serious pore-plugging. Moreover, the water flux decay rate (FDR) remained below 19.6%, when modified membrane treating soybean oil/water emulsion for 6 cycles, presenting an excellent anti-fouling performance. Addnl., the water flux recovery rate (FRR) was over 99.3% after alkali cleaning, indicating the modified membrane possessed excellent cleaning pH-responsiveness. The above anal. exhibited that the synergistic effect of hydrophilic micro-domains and oleophobic micro-domains not only slows down the attachment of hydrophobic pollutants but also promotes the separation of hydrophobic pollutants during chem. cleaning, which greatly improves its anti-fouling performance and expands its application prospect.

Robin, Clement published the artcileAdsorption of poly(methacrylic acid) onto differently charged silica nanoparticles and its consequences on particles clustering, SDS of cas: 13822-56-5, the publication is Colloids and Surfaces, A: Physicochemical and Engineering Aspects (2022), 128287, database is CAplus.

This work aims at gaining a comprehensive picture of the interactions between three differently functionalized silica nanoparticles and a polyacid – PMAA namely – in aqueous media. Native silica nanoparticles and silica nanoparticles functionalized with amine or quaternary amine groups are either neg. or pos. charged with various charge densities, whereas PMAA chains display an increasing neg. charge d. as the pH is increased from 3 to 9. Adsorption isotherms were obtained by Total Organic Carbon (TOC). It was shown that native silica interacts only weakly with PMAA while stronger adsorptions were evidenced for the two amine-functionalized silica. Whereas electrostatic attractive interactions between pos.-charged surfaces and neg.-charged PMAA are driving the adsorption at pH larger than 3, hydrophobic interactions between the Pr moieties of the grafts at the silica surfaces and the Me groups of the PMAA hypercoils are dominating at low pH value. In this last case, the more hydrophobic the silica surface is, the higher the adsorption. Contrary to expectations, hydrophobic interactions (dominating at low pH) seem to be stronger than attractive electrostatic interactions (dominating at pH larger than 3) as adsorbed amounts are larger in the first case. Small-angle X-ray scattering experiments were performed on PMAA/silica dispersions under the condition of saturation adsorption in order to correlate the extent of particle dispersion with polymer/surface interactions. The stronger the polymer/surface interactions, the more compact aggregates are formed.

Tang, Ni published the artcileAmine- and thiol-bifunctionalized mesoporous silica material for immobilization of Pb and Cd: Characterization, efficiency, and mechanism, Safety of 3-(Trimethoxysilyl)propan-1-amine, the publication is Chemosphere (2022), 291(Part_1), 132771, database is CAplus and MEDLINE.

In this study, a two-step functionalizing strategy by combining co-condensation with grafting procedures was employed to synthesize well-ordered Amino- and Thiol-Bifunctionalized SBA-15 (ATBS) mesoporous silica. Its physicochem. properties, performance, and mechanisms in immobilization of toxic metals Pb and Cd in water and soil were investigated. After bi-functionalization, X-ray diffractometer, transmission electron microscope, and N₂ adsorption-desorption measurements confirmed that the ATBS maintained a highly-ordered mesoporous structure, large surface area and pore volume The elemental anal., Fourier transform IR spectroscopy and XPS evidenced the successful incorporation of amine and thiol groups into ATBS. These structure and functional characteristics of ATBS benefited Pb and Cd sorption. Sorption isotherms of Pb and Cd were better fit with Sips and Redlich-Peterson models. Sorption kinetics suggested that Pb sorption was mainly regulated by chem. reactions, whereas both diffusion process and chem. reactions were rate-regulating steps in Cd sorption. ATBS showed the maximum sorption capacities for Pb and Cd at 120 and 38 mg g-1, resp. The sorption mechanisms revealed by XPS measurements suggested that Cd sorption was mainly attributed to thiol groups while Pb was efficiently bond to both thiol and amino groups. High and stable sorption efficiencies were attained in the pH range of 4-6, with a higher affinity towards Pb than Cd. Furthermore, its ability to immobilize Pb and Cd in soils was examined with an incubation experiment, which showed that ATBS reduced 30-56% of MgCl2-extractable Pb and Cd in a contaminated soil. The synthesized sorbent via the two-step functionalizing strategy shows high sorption efficiency towards Pb and Cd, and thus it has potential application in remediating Pb and Cd contaminated water and soils.

Cao, Jiawei published the artcilePreparation and multiple applications of integrated Zn-Al layered double hydroxide@polydopamine nanocomposites, Recommanded Product: 3-(Trimethoxysilyl)propan-1-amine, the publication is Materials Today Communications (2022), 103650, database is CAplus.

The preparation and application of inorganic-organic hybrid nanomaterials is a hot research topic at present. Herein, we combined Zn-Al layered double hydroxide (Zn-Al LDH) with mesoporous polydopamine (MPDA) to prepare two integrated Zn-Al LDH@MPDA nanocomposites under the modification of linker (1,3,5-benzoyl chloride (TMC) or (3-aminopropyl) trimethoxysilane (APTMS)), namely Composite T (modified by TMC) and Composite A (modified by APTMS), which were then evaluated for dye adsorption, adriamycin hydrochloride (DOX) loading, photothermal conversion experiment, and antibacterial test. The characterization results showed that MPDA can be successfully loaded on Zn-Al LDH with the modification of the two linkers, but the sp. surface area, pore-volume, average pore size, and electronegativity of Composite T were all higher than those of composite A, thus being more advantageous in adsorption of cationic dye. Composite T possesses a high loading capacity for DOX, whose loading efficiency and encapsulation efficiency are 478.3% and 95.7%, resp. In addition, Composite T also shows a high photothermal conversion efficiency of 27.9%. Furthermore, Composite T exhibits excellent antibacterial activity against Escherichia coli (E. coli) and Staphylococus aureus (S. aureus). Therefore, the designed Zn-Al LDH@MPDA nanocomposites would be a promising candidate for a myriad of industrial application fields.

Different graphene structures have received much attention due to their unique chem. and electron properties. In this report, we use heteroatom-doped graphene to coordinate Co2+ for use in photoelectrochem. cells. Flower-like TiO2 photoelectrode morphol. was used as a semiconductor. Its surface was covalently modified with Co2+ coordinated nitrogen and sulfur-doped graphene quantum dot (S, N-GQD). S, N-GQD was used to improve visible light absorption and electron transport properties. Also, cobalt ions were coordinated with pyridinic nitrogen in the GQD structure and, like the cobalt-bipyridine complexes, acted as a catalyst for the water oxidation reaction. The modified photoelectrode significantly improved cell performance and resulted in a photocurrent d. of 1.141 mA/cm². To study the electronic structure of the compounds in more detail, we also used d. functional theory (DFT) calculations The obtained results confirmed the effective interactions of cobalt and S, N-GQD, and showed the energy levels and band gaps in agreement with the exptl. results. This study led to the presentation of a new and robust strategy to improve the optical and catalytic performance of TiO2 nanoarrays in photoelectrochem. cells.

Raj, A. F. P. Allwin Mabes published the artcileRemoval of Pb²⁺, Cr³⁺ and Hg²⁺ ions from aqueous solutions using SiO₂ and amino-functionalized SiO₂ particles, Name: 3-(Trimethoxysilyl)propan-1-amine, the publication is Journal of Sol-Gel Science and Technology (2022), 103(1), 290-308, database is CAplus.

Herein we present silica (SiO₂) and amino-functionalized SiO₂ particles (NH₂@SiO₂) based on the Stober method involving the reaction of hydrolysis and condensation of alkoxide precursors tetraethoxysilane (TEOS), 3- (trimethoxysilylpropyl) diethylenetriamine (DETA) and (3-aminopropyl) trimethoxysilane (APTMS) for specific and selective removal of heavy metal ions such as Lead (Pb²⁺), Chromium (Cr³⁺) and Mercury (Hg²⁺). The prepared SiO₂ and NH₂@SiO₂ particles were characterized by Fourier IR Spectroscopy (FTIR) spectroscopy, thermogravimetric anal. (TGA), sp. surface area (BET), transmission electron microscopy (TEM), zeta potential (¦Æ) measurements and potential titration measurements. We studied the adsorption efficiency toward heavy metal ions (Pb²⁺, Cr³⁺ and Hg²⁺) in model salt solutions The adsorption process was evaluated in terms of adsorption efficiency, adsorption capacity, adsorption isotherms, kinetics and thermodn. parameters and desorption efficiency based on the result of the at. absorption spectroscopy (AAS) measurements for Pb²⁺ and Cr³⁺ ions and inductively coupled plasma optical emission spectrometer (ICP-OES) measurements for Hg²⁺. The results showed the highest adsorption efficiency and capacity for heavy metal ions (Pb²⁺, Cr³⁺ and Hg²⁺) by NH₂@SiO₂ using APTMS. Furthermore, the adsorption efficiency was 99.3% for Pb²⁺, 98.4% in the case of Cr³⁺ ions and 88% for Hg²⁺. The adsorption process for Pb²⁺, Cr³⁺ and Hg²⁺ ions using non-functionalized SiO₂ and NH₂@SiO₂ particles follows pseudo-second-order kinetics and is best described by the Langmuir adsorption model. The desorption results showed potential for reusing NH₂@SiO₂ particles with more than 91.8% desorbed Pb²⁺ ions using 0.1 M HCl and 100% desorbed Hg²⁺ ions using 1.5 M C6H8O7. Three alkoxide precursors (tetraethoxysilane (TEOS), 3-(trimethoxysilylpropyl), diethylenetriamine (DETA) and (3-aminopropyl) trimethoxysilane (APTMS)) were used in the one-pot synthesis of silica (SiO₂) and amino-functionalized SiO₂ (NH₂@SiO₂) particles. The prepared adsorbent materials were characterized and used for adsorption tests and desorption toward heavy metals ions (Pb²⁺, Cr³⁺ and Hg²⁺). Adsorption efficiency, adsorption capacity, adsorption isotherms, kinetics and thermodn. parameters were detected.

Shao, Yu published the artcileSingle Solid Precursor-Derived Three-Dimensional Nanowire Networks of CuZn-Silicate for CO₂ Hydrogenation to Methanol, Safety of 3-(Trimethoxysilyl)propan-1-amine, the publication is ACS Catalysis (2022), 12(10), 5750-5765, database is CAplus.

Hydrogenation of CO₂ to MeOH is one of the most promising technologies in mitigating the emissions of CO₂ and tackling the challenge of climate change. In this work, we present a synthetic protocol for preparing a Cu-ZnO-based heterogeneous catalyst supported by siliceous nanowire networks from a single solid precursor with a tunable composition The resulting Si-Cu-Zn catalysts were evaluated with the MeOH synthesis from the CO₂ hydrogenation reaction operated at moderate conditions (30 barg and 200-280¡ãC). A specific MeOH yield of 402 mg_MeOH¡¤g_Cu^-1¡¤h^-1 and a MeOH selectivity of 51% were obtained at 240¡ãC. Such a performance was attributed to several structural and compositional merits, granted through the attentively engineered synthetic procedures. Small Cu nanoparticle (NP) size was achieved and maintained by the high dispersion of Cu to the at. level in the precatalyst and the incorporation of ZnO as a structural promoter. Moreover, the desirable Cu-ZnO synergistic effect can be further attained from the strong metal-support interaction (SMSI) between the Cu NPs and the partially reduced ZnO phase. Lastly, the robust siliceous nanowire networks provided decent spatial confinement to contain the growth of Cu NPs while offering high accessibility with the macroscopic porous morphol. The catalyst exhibited stable performance over a week’s long stability test while keeping its structural integrity intact. Overall, this study may offer an alternative design and synthesis strategy for the well-received Cu-ZnO system to approach its high performance in CO₂ hydrogenation.

Mirzaei-Kalar, Zeinab published the artcileNew ZnFe₂So₄;@SiO₂@graphene quantum dots as an effective nanocarrier for targeted DOX delivery and CT-DNA binder, Related Products of catalysis-chemistry, the publication is Journal of Molecular Liquids (2022), 119904, database is CAplus.

The current study pronounces the synthesis and characterization of ZnFe₂O₄, ZnFe₂So₄@SiO₂, graphene quantum dots (GQDs) and ZnFe2O4@SiO2@GQDs nanoparticles by different techniques such as VSM, XRD, IR, UV-Vis and SEM. For application in targeted drug delivery, then GQDs were immobilized on the surface ZnFe₂So₄@SiO₂ via covalent linkage to surface amino groups. The competence of ZnFe₂So₄@SiO₂@GQDs nanoparticles was assessed by loading and releasing of doxorubicin (DOX) as a standard anticancer drug at pH = 5 (pH of cancerous cell) and pH = 7.4 (pH of healthy cell). The attained results authenticate the pH sensitive release behavior of ZnFe₂So₄@SiO₂@GQDs nanoparticles by releasing more DOX at cancerous pH (70%) than healthy pH (28%). To appraise the biol. manner, ZnFe₂So₄@SiO₂@GQDs nanoparticles were screened for their CT-DNA binding tendency by means of spectroscopic methods. The gained results of absorption spectroscopy and competitive fluorescence studies disclosed that nanoparticles bind to DNA through the intercalation mode and the loading of DOX on the nanocarrier has increased CT-DNA binding affinity up to 300 times. The cytotoxicity activity of ZnFe₂So₄@SiO₂@GQDs and ZnFe₂So₄@SiO₂@GQDs/DOX by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay revealed on cancerous HeLa cell and healthy HEK-293 cell revealed that both nanoparticles exhibit concentration-dependent behavior on both cell lines, so that with increasing nanoparticle concentration, the cell viability percentage decreases, although nanocarriers containing DOX expression a more severe effect. Treatment of HeLa cells with 10 ¦Ìg/mL of the ZnFe₂So₄@SiO₂@GQDs/DOX nanoparticles showed that the nanoparticles induce cell death by apoptosis and cause detention of cell cycle in G2 phase. The results of the study expression the potential of the nanocarrier for targeted and controlled drug delivery, which should be given more attention and modified as a nanocarrier.
