1. Effect of calcination temperature on the bioactivity of a sol-gel-derived 40CaO-60B₂O₃ glass composition.
PMID:日期:2026-01-01Sol-gel-derived borate glasses are highly bioactive where they demonstrate rapid production of hydroxycarbonated apatite (HCA), in vitro; making them promising candidates for biomedical applications. Calcination, a critical step in sol-gel processing, significantly influences product properties. This study investigated the effect of calcination temperature on the texture, structure, as well as the reactivity and bioactive properties of sol-gel-derived 40CaO-60B₂O₃ (mol%) samples synthesized from calcium lactate pentahydrate. X-ray diffraction (XRD) confirmed that samples calcined between 400 and 600 °C were amorphous, whereas crystallization occurred when samples were calcined at 700 °C. Attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy revealed a decrease in BO units with increasing calcination temperature. There was a decrease in specific surface area, attributable to reduced network connectivity and densification, which correlated with a decrease in vapor reactivity, as indicated by dynamic vapor sorption analysis. Bioactivity was confirmed by HCA formation within 7 days in simulated body fluid in all calcined samples, as characterized by ATR-FTIR, XRD, and scanning electron microscopy. In particular, samples calcined at 400 and 500 °C exhibited HCA formation within 1 day. Thermogravimetric analysis revealed that the sample calcined at 400 °C contained the highest amount of organic residues from sol-gel processing. In contrast, the sample calcined at 500 °C combined high bioactivity with optimal thermal decomposition, indicating that this calcination temperature may be suitable for this glass composition. In summary, the successful use of calcium lactate pentahydrate as a low-cost precursor highlights its scalability and potential for producing high-performance sol-gel-derived bioactive borate glasses.

2. Nanocomposite hydrogels reinforced with vinyl functionalised silica nanoparticles.
PMID:日期:2025-01-01This work reports double network hydrogel/silica nanocomposites with increased mechanical toughness and strength compared to their soft polymer-only counterparts. Applications are in tissue repair, such as cartilage, soft robotics and motion sensing. Covalent coupling of the sol-gel silica nanoparticles and the gel is vital because the gel swells on contact with water. Here, coupling was achieved through vinyl functionalisation of the silica nanoparticles (VSNPs) that enabled cross-linking to the network using photopolymerisation. The double network gel was an interpenetrating network hydrogel (IPNG) with 2-acrylamido-2-methylpropane-sulfonic acid (AMPS) as the first network, and acrylamide (AAm) as the second network. The effect of vinyl silica nanoparticle size and loading concentration were investigated on swelling behaviour, microstructure, compressive properties and nanoparticle retention. Increased size and loading concentration of VSNPs allowed for tailorability of swelling properties; nanocomposite IPNGs swelled less (88%) compared to control gels (97%). The nanocomposite IPNGs, with 20Wt% VSNPs, exhibited a max compressive strength of 810 ± 80 kPa at a strain of 75 ± 6%, similar to the lower range of articular cartilage, and an order of magnitude higher strength than control gels (90 ± 20 kPa, at a strain of 40 ± 3). SEM images show VSNP-polymer integration, with nanoparticles within the mesh walls. The nanocomposite structure provides reinforcement and toughness to soft IPNGs, making them suitable candidates for soft material repair.

3. The poor reliability of thermal conductivity data in the aerogel literature: a call to action!
PMID:日期:2024-01-01Aerogels are an exciting class of materials with record-breaking properties including, in some cases, ultra-low thermal conductivities. The last decade has seen a veritable explosion in aerogel research and industry R&D, leading to the synthesis of aerogels from a variety of materials for a rapidly expanding range of applications. However, both from the research side, and certainly from a market perspective, thermal insulation remains the dominant application. Unfortunately, continued progress in this area suffers from the proliferation of incorrect thermal conductivity data, with values that often are far outside of what is possible within the physical limitations. This loss of credibility in reported thermal conductivity data poses difficulties in comparing the thermal performance of different types of aerogels and other thermal superinsulators, may set back further scientific progress, and hinder technology transfer to industry and society. Here, we have compiled 519 thermal conductivity results from 87 research papers, encompassing silica, other inorganic, biopolymer and synthetic polymer aerogels, to highlight the extent of the problem. Thermal conductivity data outside of what is physically possible are common, even in high profile journals and from the world's best universities and institutes. Both steady-state and transient methods can provide accurate thermal conductivity data with proper instrumentation, suitable sample materials and experienced users, but nearly all implausible data derive from transient methods, and hot disk measurements in particular, indicating that under unfavorable circumstances, and in the context of aerogel research, transient methods are more prone to return unreliable data. Guidelines on how to acquire reliable thermal conductivity data are provided. This paper is a call to authors, reviewers, editors and readers to exercise caution and skepticism when they report, publish or interpret thermal conductivity data. Graphical Abstract

4. {"_":"Spinel ZnCrO nanorods synthesized by facile sol-gel auto combustion method with biomedical properties.","sub":["2","4"]}
PMID:日期:2023-01-01In this study, spinel zinc chromite nanorods (ZnCrO NRs) were successfully manipulated by a simple sol-gel auto combustion process employing urea as fuel. The sample was only required to sinter at 500 °C for 2 h to obtain the single crystalline phase. The phase formation, crystallinity, and surface topography of synthesized ZnCrO NRs were explored by X-ray diffraction (XRD), UV-Vis reflectance spectroscopy (UVDRS), Fourier transform infrared (FTIR) spectroscopy, field emission scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM), energy dispersive X-ray (EDX) spectroscopy, and vibrating sample magnetometry (VSM). XRD analysis confirms the formation of spinel ZnCrO NRs. The FTIR spectrum displays the two vibrational peaks of Cr-O, and Zn-O at 489 and 615 cm, correspondingly. These vibrational bonds were correlated with ZnCrO and revealed the production of cubic spinel ZnCrO NRs. FESEM indicates the presence of hexagonal-rod-shaped particles. EDX spectrum demonstrates the elemental composition of the ZnCrO NRs and confirms the primary peak of Zn, Cr, and O. The obtained ZnCrO NRs exhibit an antiferromagnetic behavior. The bandgap energy of ZnCrO NRs was ascertained and was shown to be 3.45 eV. Furthermore, the antifungal and antibacterial effect of ZnCrO NRs was examined against pathogenic strains by disc diffusion technique. Besides these, the antimalarial activity of ZnCrO NRs was studied against . Thus, the as-synthesized ZnCrO NRs showed significant antibacterial, antifungal and antimalarial activity and may be helpful for research opening a novel horizon in nanomedicine. Graphical abstract.

6. U(rano)topia: spectral skies and rainbow holograms for silica aerogel artworks.
PMID:日期:2023-01-01Micro/nano structuring in distinct chemical compositions has demonstrated added values which could be utilized in various modern applications and products through the lens of visual arts. Silica aerogel is a prominent example of such a nanostructure, with which we recently utilized to accommodate the unique design of high jewelry. Using its natural shades and transparent layers, silica aerogel can be described by the first author, a visual artist, as an extremely beautiful and ethereal material that closely resembles a piece of sky. Ultimately silica aerogel can be exploited as a sky-like material, and has been used in numerous collaborations amongst artists and scientists to bring to life concepts, like rainbow holograms on silica aerogel dried by high-temperature supercritical drying with methanol. In this short review, we show how such collaborations the authors have been proceeding are evoking developments in science and technology as well as in design, fashion and art industries. The series of the collaborative research has been contributing to the development of quality end products by merging new technologies, novel functional materials and innovative manufacturing processes with visual arts.

7. Industrial applications of sol-gel derived coatings.
PMID:日期:2022-12-02Sol-gel derived coatings have many practical applications in different industries. In this paper, HI-GARD hard coat, multi-layer antireflective coatings, and an anti-glare coating with organic particles are described. Optical and mechanical performances of these coatings are discussed in addition to adhesion properties. The HI-GARD hard coat was dip or spin coated from a sol by hydrolyzing alkoxysilanes with water in an acidic condition. The hard coat acts as a protective coating for optical lenses with excellent optical properties with a Bayer ratio of 4.8 and an adhesion of 5B. The multi-layer antireflective coatings were prepared by incorporating titanium oxide sol into the HI-GARD hard coat solution to obtain different layers by spin-coating with tunable refractive index. These two-layer or three-layer antireflective coatings increase transmittance by at least 3% compared to an uncoated glass substrate. Anti-glare coatings were spray-coated at room temperature on glass substrates by embedding cationic or anionic polystyrene particles in an acid-hydrolyzed silane sol. The anti-glare coating with organic particles can provide a significant glare reduction with a haze value of up to 13% for display surface without sparkling. In addition to these transparent coatings, non-transparent sol-gel derived coatings such as a sol-gel non-stick coating for cookware and bakeware, and two zinc-silicate protective coatings hydrolyzed from a silane with addition of zinc dusts for corrosion protection are also discussed briefly. The schematic structures of the hard coat on CR-39® substrate, three-layer AR coatings on glass substrate, and organic particle embedded anti-glare coatings on glass substrate, and their respective transmittance or reflective curves.

8. Sol-Gel ceramic glazes with photocatalytic activity.
PMID:日期:2022-01-01A frit is a glassy ceramic composition that has been fused, quenched, and granulated. A single frit or a mixture of frits and ceramic materials forms a ceramic glaze. The purpose of this pre-fusion is to render any soluble and/or toxic components insoluble by rendering it inert in a glassy composition with silica and other added oxides. The ceramic glaze dispersed in water (ceramic slip) is deposited on a ceramic body and fired for waterproofing and aesthetic purposes. Multicomponent frits (zinc-potassium borosilicate system) with similar behavior to conventional ceramic frits for single-firing ceramic glazes ("monoporosa" glazes fired at 1080 °C) were prepared by Sol-Gel methods (monophasic and polyphasic gels) avoiding the pre-fusion and characterized as photocatalytic agents (showing high degradation activity on Orange II). The effect of doping with bandgap modifiers (VO, SbO and SnO) and also with devitrification agents (ZrO to crystallize zircon, AlO to anorthite, MoO to powellite and ZnO to gahnite ZnAlO) were analyzed. Multicomponent frits (zinc-potassium borosilicate system) with similar behavior to conventional ceramic frits for single-firing glazes (1080 °C) prepared by Sol-Gel methods (monophasic and polyphasic gels), without pre-fusion, shows photocatalytic activity.

9. Silver nanoparticle incorporation into flexible polyamide 12 membranes.
PMID:日期:2022-01-01To meet the demands of the market and society, the development of structured polymeric materials for application in the medical field is constantly increasing. Over the last decades, metallic silver nanoparticles have been explored due to their antimicrobial action. Here, we aimed to incorporate metallic silver nanoparticles into polymeric pieces obtained by additive manufacture via a chemical route involving silver nitrate and sodium borohydride. Polyamide 12 membranes were obtained by selective laser sintering, which was followed by washing, pretreatment, and functionalization with the alkoxides tetraethylorthosilicate and 3-aminopropyl tetraethoxysilane. For nanoparticle preparation and incorporation, a chemical route was tested under different conditions. The samples were characterized by techniques, such as X-ray diffraction, ultraviolet-visible spectroscopy, and infrared vibrational spectroscopy. Nanoparticle formation and incorporation into the polyamide 12 membranes were demonstrated by the absorbance band at 420 nm, which indicated that the particles measured between 10 and 50 nm in size; by the X-ray diffraction peaks at 2θ = 38, 44, and 64°, which are typical of crystalline silver; and by vibrational spectroscopy, which evidenced that the nanoparticles interacted with the polyamide 12 nitrogen groups. Polyamide 12 membranes containing metallic silver nanoparticles have promising biomedical applications as antimicrobial wound dressings associated with drug carriers.

10. Silica-silk fibroin hybrid (bio)aerogels: two-step versus one-step hybridization.
PMID:日期:2021-01-01In this study, silk fibroin as a highly promising naturally occurring biopolymer extracted from silkworm cocoon is applied to mechanically reinforce silica aerogels. To this aim, two different approaches for the incorporation of silk fibroin into the silica network are compared: (1) a one-step acid catalyzed and (2) a two-step acid-base catalyzed sol-gel reaction. The total organosilane concentration, as well as the SF to silane mass fractions, regulated the hybridization process to proceed either through a one-step or two-step sol-gel reaction. In both processes, for an efficient chemical mixing the silk fibroin components with the silane phase, a silane coupling agent, 5-(trimethoxysilyl) pentanoic acid (TMSPA), comprising carboxylic acid groups and a pentyl hydrocarbon chain has been used. For a low organosilane content (3.4 mmol) along with a high SF to silane mass ratio (15-30%), the gelation of the silane and silk fibroin phases took place in a one-pot/one-step process in the presence of an acid catalyst in an entirely aqueous system. In the two-step synthesis approach, which was applied for high initial silane contents (17 mmol), and low SF to silane mass ratios (1-4%), first, the gelation of the silk fibroin phase was triggered by addition of an acid catalyst followed by a more pronounced condensation of the silane catalyzed by the addition of the base. Both synthesis approaches led to materials with promising mechanical properties-being 1) the one-step process resulting in gels with much better compressibility (up to 70% of strain), low density (0.17-0.22 g cm) and three orders of magnitude improvement in the Young's modulus (13.5 MPa) compared to that of the pristine silica aerogel but with rather high shrinkage (30-40%). The two-step process in principle could result in the hybrid aerogel with interesting bulk density (0.17-0.28 g cm) with lower shrinkage (10%), but the resultant aerogel was stiff and fragile. Also, both approaches led to a significant reduction in the time required to prepare strong hybrid aerogels compared to conventional hybrid polymer-silica aerogels with the utilization of an entirely aqueous synthesis approach for a wide range of applications.
