Leveraging Radiation-triggered Metal Prodrug Activation Through Nanosurface Energy Transfer for Directed Radio-chemo-immunotherapy.

Metal-based drugs currently dominate the field of chemotherapeutic agents; however, achieving the controlled activation of metal prodrugs remains a substantial challenge. Here, we propose a universal strategy for the radiation-triggered activation of metal prodrugs via nanosurface energy transfer (NSET). The core-shell nanoplatform (Ru-GNC) is composed of gold nanoclusters (GNC) and ruthenium (Ru)-containing organic-inorganic hybrid coatings. Upon X-ray irradiation, chemotherapeutic Ru (II) complexes were released in a controlled manner through a unique NSET process involving the transfer of photoelectron energy from the radiation-excited Ru-GNCs to the Ru-containing hybrid layer. In contrast to the traditional radiation-triggered activation of prodrugs, such an NSET-based system ensures that the reactive species in the tumor microenvironment are present in sufficient quantity and are not easily quenched. Additionally, ultrasmall Ru-GNCs preferably target mitochondria and profoundly disrupt the respiratory chain upon irradiation, leading to radiosensitization by generating abundant reactive oxygen species. Consequently, Ru-GNC-directed radiochemotherapy induces immunogenic cell death, resulting in significant therapeutic outcomes when combined with the programmed cell death-ligand 1 (PD-L1) checkpoint blockade. This NSET strategy represents a breakthrough in designing radiation-triggered nanoplatforms for metal-prodrug-mediated cancer treatment in an efficient and controllable manner.

Molecular Layer Deposition of Metal Phosphonates: A New Class of Hybrid Coating Layers

Atomic layer deposition (ALD) is a vapor phase thin film deposition technique where materials can be grown atom-by-atom in a layer-by-layer manner. Over the course of just few years, it has become to be one of the most sophisticated methods of producing high quality thin films with control at the sub-nanometer scale. Molecular layer deposition (MLD) is a variant of ALD where molecular fragments are intentionally built into the growing films.MLD is one of the techniques which allows to grow organic-inorganic hybrid materials with thickness control at sub-nanometer level.1 Nowadays, organic-inorganic hybrid materials have been found to attract a lot of attention because of their distinctive properties obtained by combining chemical and physical properties of organic and inorganic segments. Numerous hybrid materials have been synthesized by MLD over the time; however, commercial application of those materials are still a challenge due to their hydrolytic instability in most cases. Perhaps, the most widely used hybrid materials in our daily life is polysiloxanes, or commonly called as silicones, a silicon-based hybrid material . The hydrolytic stability of Si-C and Si-O-Si bonds is the main reason of their practical usage as hybrid materials. Similarly, organophosphorus compounds are an important class of materials because they offer several alternatives to silicon-based linking in the field of hybrid materials. Most of the hybrid films produced by MLD technique contain C, O, N, and S elements in the organic part. Hybrid materials containing P-atoms are yet to be explored by MLD.Among others, metal phosphonates, in particular, an important class of organophosphorus compound, show promising application covering from ion-exchange, proton conductors, catalysts, sensors, membranes, fire retardants etc.2,3 Examples of metal-organic compounds based on phosphonic acid derivatives can be found in literature stemming several decades back. Phosphonates are widely considered as an effective metal chelating ligand. Their dianionic tetrahedral form (RPO3 -2) enables different modes of coordination with metal which is not possible with the extensively used contemporary carboxylate (RCO2 -2) ligands. P-O-M and P-C linkages are quite stable, and therefore organophosphorous compounds with phosphonate ligands have been used to produce thermally and chemically stable hybrid materials by several other techniques.4 Here, we report the synthesis of novel aluminum phosphonate hybrid layers obtained with MLD method. Trimethyl aluminum (TMA) has been used as the metal source and two different novel phosphonate ester precursors with two different organic groups have been used to grow the aluminum phosphonate layers. The growth characteristics of the layers have been studied by in situ ellipsometry, whereas the as-grown films have been characterized with different ex situ techniques like FTIR, XPS, XRD, SEM and AFM. As-deposited metal phosphonate layers show superior thermal (>500 0C in air) and complete water stability. We believe, this kind of metal phosphonate layers may open up new opportunities in the field of organic-inorganic hybrid coatings for various applications. Meng, X. J. Mater. Chem.

The chemical bonding of extruded polystyrene foam with mortar through UV curable organic-inorganic hybrid coatings

UV curable organic-inorganic hybrid (OIH) coatings were used to modify the extruded polystyrene foam (XPSF) surfaces to increase the bonding strengthen (BS) of XPSF/mortar composite (XMC). OIH coatings contained polyurethane acrylate, hexanediol and nanoparticles with different dimensions. With the addition of nano-SiO2 and halloysite nanotubes, the BS-D (BS in dry state) & BS-W-2H/7D (BS in wet state after 2-hour/7-day drying) values for modified XMC were increased from 0.050 & 0.039/0.047 MPa to 0.245 & 0.196/0.356 and 0.312 & 0.233/0.323 MPa. The chemical bonding between SiO2/-COOH from UV coating and hydration products in mortar improved the bonding state.

Epoxy Coatings Doped with (3-Aminopropyl)triethoxysilane-Modified Silica Nanoparticles for Anti-Corrosion Protection of Zinc

Epoxy (EP) coatings containing silica (SiO2) and (3-Aminopropyl)triethoxysilane-modified silica (SiO2-APTES) nanoparticles were prepared via the dip-coating technique on a zinc substrate. A detailed study was performed regarding their incorporation into the matrix, followed by the investigation of the newly obtained organic–inorganic hybrid coatings’ anti-corrosive properties. The two methods of embedding the nanoparticles were (I) modification of the silica nanoparticles with APTES followed by their introduction into the epoxy resin, and (II) functionalization of the silica nanoparticles in the epoxy gel before the addition of the hardener. It was observed that through the second method, the coating was homogeneous, with no sign of agglomerates. The nanoparticles were subjected to morpho-structural and physical–chemical analysis using Fourier-Transform Infrared Spectroscopy and Transmission Electron Microscopy, while the coatings were examined through Scanning Electron Microscopy and Energy-Dispersive X-Ray Spectroscopy, contact angle measurements and adhesion tests. The anti-corrosive performance of epoxy-coated zinc was analyzed using electrochemical impedance spectroscopy and polarization curves to investigate the impact of silanized SiO2 nanoparticle incorporation. Based on long-term corrosion testing, the epoxy-SiO2-APTES composite coatings showed a higher corrosion resistance than the undoped epoxy layer.

Composite Silica-Based Films as Platforms for Electrochemical Sensors.

Sol-gel-derived silica thin films generated onto electrode surfaces in the form of organic-inorganic hybrid coatings or other composite layers have found tremendous interest for being used as platforms for the development of electrochemical sensors and biosensors. After a brief description of the strategies applied to prepare such materials, and their interest as electrode modifier, this review will summarize the major advances made so far with composite silica-based films in electroanalysis. It will primarily focus on electrochemical sensors involving both non-ordered composite films and vertically oriented mesoporous membranes, the biosensors exploiting the concept of sol-gel bioencapsulation on electrode, the spectroelectrochemical sensors, and some others.

Enhance of Anticorrosive Properties of Green-PU-Silica Coatings by Incorporation of Lignin

The tailored combination of organic polymers and inorganic ceramics can produce organic-inorganic hybrid (OIH) coatings to act as corrosion protection barriers.1 ,2 In this work, we proposed the use of glycerol and lignin as polyol sources to prepare green polyurethane to be used in the sol-gel synthesis of PU-silica hybrid coating for steel corrosion protection. The PU pre-polymer was synthesized from MDI (4,4’-methylenebis (phenyl isocyanate)), glycerol and lignin, and then it was functionalized with APTES ((3-aminopropyl) triethoxysilane) to ensure the covalent conjugation with polysilanol network formed from TEOS (Tetraethyl orthsilicate) sol-gel reactions leading to a class II hybrid. Three samples were synthesized varying the proportion between the polyols, one sample containing only glycerol (ZL_PU-S) and the others with a molar ratio of GlyOH:LigOH of 7.5 and 16.1 (FL_PU-S and HL_PU-S, respectively).The effects of lignin content on the structure and properties were evaluated. FTIR and 13C NMR showed the formation of the PU-silica hybrid and the total incorporation of lignin to the PU chain. TGA showed that the presence of lignin into the OIH matrix improved the thermal stability allowing to continuous increase of the initial temperature of mass loss: T5% = 173, 186 and 190 °C for ZL_PU-S, HL_PU-S and FL_PU-S, respectively. The steel substrate coated with the OIH show a water contact angle of 90° for the samples HL_PU-S and FL_PU-S and 80° for ZL_PU-S. The electrochemical impedance spectroscopy analysis performed in a three electrode cell configuration with a NaCl 3.5% solution, showed that the coating with the higher lignin concentration, FL_PU-S, have a |Z| of over 1010 Ω.cm2 for the lowest frequency point and a phase angle of approximately -90° during the 28 days of analysis. The FL_PU-S had better performance than the coating without lignin, ZL_PU-S, that presented |Z|=107 Ω.cm2 on the initial period of immersion with a decrease of two decades in value through out the subsequent period of analysis. In summary, the addition of lignin to the PU polymeric matrix enables the production of a green OIH coating with high efficiency for corrosion protection of steel substrates.Acknowledgments: This work was supported by the Brazilian funding agencies CNPq, FAPESP, CAPES and by PROPe UNESP.Keywords: Renewable feedstock, green coating, PU-silica, lignin, corrosion protection, sol-gel process, hydrophobic coating.1-BRAZ, Á.

One-step assembly of organic-inorganic hybrid coatings with superior thermal insulation, sustainable antifogging and self-cleaning capabilities

Multifunctional transparent glass integrating energy-saving and antifogging properties has receiving continuous attention in basic research and practical applications, which is still plagued by the lack of simple and general methods for low-cost and large-area fabrication. Herein, a multifunctional window with high thermal insulation, antifogging, and self-cleaning functions is rationally fabricated via coating a mixture of polyacrylic acid (PAA), polypropylene glycol (PPG), 3-glycidyloxypropyltrimethoxysilane (KH-560), and cesium tungsten bronze (CWO) nanoparticles on a monolayer film. The synergistic effect between the plentiful hydroxyl/carboxyl groups of PAA/PPG and the nano-textured surface induced by CWO nanoparticles enabled the monolayer film to exhibit superhydrophilic, self-cleaning and antifogging capabilities. The film maintains its antifogging properties even after 80 rubbings of dust-free cloth and 120 days of exposure tests at room temperature. Moreover, the as-prepared window can reduce the indoor temperature by 15.8 °C compared to a normal window at noon. The energy simulation results demonstrate that such windows can reduce energy consumption by 18.9 % in local cities compared to traditional windows. The high visible light transmittance, low haze, stable and durable antifogging ability, distinguished energy-saving effect and climate adaptability, as well as the solution-based process of this multifunctional window make it promising for architectural and automotive glass applications.

Ce nanoparticles and sol-gel hybrid organic-inorganic coatings maximize corrosion protection in the anodized AA2024-T3

We demonstrate that the corrosion resistance of the AA2024-T3 alloy can be maximized with the application of top protective sol-gel hybrid organic-inorganic coatings. Samples combining Ce nanoparticles within the pores of the anodic layer with the top sol-gel coatings were observed to outperform samples featuring only the coating. This research unravels the self-healing capability against corrosion of the sol-gel coating when Ce nanoparticles are present, as well as a good coverage of defective regions within the oxide by the hybrid layer. This research opens a paradigm aiming at maximizing the corrosion resistance for non-ferrous anodized alloys.

Multi-layer organic-inorganic hybrid anticorrosive coatings for protection of medium carbon steel

In the current study, sol-gel technology was used to produce organic-inorganic hybrid coatings onto AISI 1045 carbon steel as a means of corrosion protection. The organic-inorganic hybrid coatings were prepared using tetraethylorthosilicate (TEOS) and 3-(trimethoxysilyl)propyl methacrylate precursors. The coatings were thermally treated and the effect of temperature and time was studied. The results of scanning electron microscopy (SEM) and atomic force microscopy (AFM) demonstrated that the coatings possess homogeneous morphologies and that their thickness decreases with increasing heat treatment temperatures. At the highest treatment the coating was 20% thinner and more than 25% more scratch resistant compared with the untreated coating. According to thermalgravimetric analysis the coating mass loss was approximately 15% up to 150 °C and 2.7% between 150 and 400 °C. The electrochemical measurements, in 3.5% NaCl aqueous solution, determined that the coatings treated at 100 °C have polarization resistance values on the order of 60 kΩ cm2 after 72 h of exposure time in saline solution. The phase angle at high frequency (close to −90° at 103-105 Hz) demonstrated that the coating presented capacitive behavior related to less aggressive corrosion in this electrolyte. Further increasing the temperature beyong 100 °C reduced the performance of the coatings as demonstrated by a decrease of the polarization resistance by about one order of magnitude and the shift of the corrosion potential to more negative values.

Study the factors affecting water vapor barrier properties of organic–inorganic hybrid coatings

Water vapor barrier materials are crucial importance in the packaging industry. Herein, a series of organic–inorganic hybrid coatings are successfully deposited onto polyethylene terephthalate (PET) film through a facile casting method. These coatings impart PET film with enhanced water vapor barrier properties. Particularly, the influencing factors for the water vapor barrier property are systematically investigated in terms of polymers, inorganic fillers and environmental pH level. The results demonstrate that the hybrid coatings comprising ethylene-vinyl alcohol copolymer resin (AQ4104) and inorganic filler with peelable structure, including micas (ME-100 and NTS) and sodium montmorillonite (K–F) significantly reduce the water vapor transmittance ratio (WVTR) of PET film. The WVTR of PET film coated with ME-100/AQ4104 hybrid is 0.7 g·m −2 /day, which is reduced by 80% than that of uncoated PET film. Also, the composite coatings comprising polyurethane resin (WPB-341) and NTS greatly reduce the WVTR of PET film to 1.0 g·m −2 /day at 20 wt% NTS content. The inorganic fillers with both small sheet diameter and peelable sheet structure are greatly advantageous for the water vapor barrier property of hybrid coatings. Additionally, the adhesion tests show that these composite coatings possess great adhesion strength, especially for NTS/WPB-341 composite coating of 4.92 N/cm. Moreover, when the environmental pH is adjusted from original alkaline to acidic, the WVTR of PET film coated with AQ4104-based composite coatings is changed, indicating the pH-dependent water vapor barrier ability. This research may provide some reference significance for the simple, low-cost and easy large-scale production of high-performance water vapor barrier coatings for packaging applications.

ALD/MLD coating of patterned vertically aligned carbon nanotube micropillars with Fe-NH2TP hybrids.

The creation of nanoscale organic-inorganic hybrid coatings with uniform architecture and high surface area, while maintaining their structural and morphological integrity, remains a significant challenge in the field. In this study, we present a novel solution, by utilizing Atomic/Molecular Layer Deposition (ALD/MLD) to coat patterned vertically aligned carbon nanotube micropillars with a conformal amorphous layer of Fe-NH2TP, which is a trivalent iron complex complexed with 2-amino terephthalate. The effectiveness of the coating is verified through multiple analytical techniques, including high-resolution transmission electron microscopy, scanning transmission electron microscopy, grazing incidence X-ray diffraction, and Fourier transform infrared spectroscopy. The Fe-NH2TP hybrid film exhibits hydrophobic properties, as confirmed by water contact angle measurements. Our findings contribute to advancing the understanding of how to grow high-quality one-dimensional materials using ALD/MLD and hold promise for future research in this area.

Copper Iodide Cluster Incorporated Luminescent Organic-Inorganic Hybrid Coating Exhibiting Both Corrosion Protection and Antibacterial Properties.

A photoluminescent organic-inorganic hybrid coating is synthesized by the incorporation of an emissive Cu4I4 core into a cross-linked coating network through Cu-P coordination bonds. The hybrid coating not only emits strong yellow emission under UV-light irradiation but also exhibits corrosion protection of the metallic surface. Moreover, bactericidal properties are studied that were first reported for Cu4I4-based hybrid light-emitting materials.

Inorganic-organic hybrid coatings from tea polyphenols and laponite to improve the fire safety of flexible polyurethane foams

Inorganic-organic hybrid coatings prepared via an impregnation assembly of eco-friendly materials exhibited dramatically flame-retardant properties on flexible polyurethane foam (FPUF). A nickel-complex of tea polyphenols (TP-Ni) was synthesized, and TP-Ni and laponite (LAP) were coated on the surface of FPUF. LAP/TP-Ni can be homogeneously dispersed on the surface of FPUF. Moreover, the melt-dripping phenomenon of 1LAP/4TP-Ni/FPUF was completely inhibited during the vertical flame test (UL-94) with 41.2 wt% weight gain, and it showed self-extinguished behaviors at once and passed the UL-94 V-0 rating. Additionally, the values of peak heat release rate and peak smoke production rate of 1LAP/4TP-Ni/FPUF were reduced by 71.6% and 60.9%, compared with the control. The content of gaseous toxic substances, such as CO and NCO-containing compounds, was also decreased, indicating the effect of TP-Ni/LAP on the toxicity suppression of flame-retardant FPUF. Encouragingly, the coatings deteriorated the tensile property of FPUF inconspicuously. Interestingly, the coatings do not contain traditional flame retardant elements, which offers an innovative approach for designing flame retardants. Thus, these inorganic-organic hybrid coatings show the promising potential to decrease the fire risk of FPUF.

Flame retarded polymer systems based on the sol-gel approach: recent advances and future perspectives

AbstractThe ease of flammability of polymers represents a key issue that limits their applications in different advanced sectors. In this context, a reliable and effective solution regards the use of flame retardants, i.e., additives that are able to slow down (or even stop) the flame propagation and to enhance the resistance to an irradiative heat flux. Among the different flame retardants designed, synthesized, and applied up-to-now, the utilization of inorganic particles, inorganic and hybrid organic-inorganic coatings has gathered a great interest from either the academic and industrial community, as these structures can provide remarkable flame retardant features to different polymer systems, in which they are embedded or applied onto. In particular, the in situ generation (through sol-gel processes, i.e. hydrolysis and condensation reactions from tailored alkoxide precursors) of ceramic phases, either in the form of particles or as surface coatings, has clearly demonstrated its effectiveness in creating a physical barrier that limits the degradation of the polymer when subjected to the application of a flame or an irradiative heat flux. It also lowers the heat and mass transfer from the degrading polymer to the surroundings and vice versa, hence providing an overall enhancement of heat and fire resistance. This review work seeks to provide an up-to-date overview of the most recent advances in the use of sol-gel methods for conferring flame retardant features to bulk polymers, cellulosic textiles (cotton), and polymer foams. In addition, the current limitations and the potential progresses of these approaches are discussed.

Polysilsesquioxane precursors stabilizing chlorotrifluoroethylene copolymerization for waterborne hybrid fluorocarbon coatings with excellent synergistic performances

An environmentally friendly, low-cost and simple method to prepare poly(tert-butyl acrylate)/poly(chlorotrifluoroethylene-co-isobutyl vinyl ether)/polysilsesquioxane (PtBA/P(CTFE-co-IBVE)/PSQ) organic–inorganic hybrid waterborne fluorocarbon coatings is reported in this article. It is worth mentioning that the PSQ precursors are used as the only stabilizer of emulsion system owing to their amphiphilicity presented after hydrolysis. The composition and morphology of composite particles, microscopic phase separation and comprehensive properties of the latex coatings are further investigated. The results show that PSQ precursor not only plays the role of emulsion stabilizer, but also improves the thermal stability and hydrophobicity of the coatings. Furthermore, the influences of MPS addition amount and flexible chain segments content on organic–inorganic phase separation and coating transparency are systematically studied to address the main challenge that organic–inorganic hybrid coatings are facing, namely, how to ensure the addition of PSQ and CTFE can endow the coating with both inherent advantages without compromising other properties such as transparency, adhesion, etc. Finally, the prepared waterborne coatings exhibit strong adhesion, excellent UV resistance and outstanding organic solvents resistance under the synergistic effect between the coating components. The understanding of PtBA/P(CTFE-co-IBVE)/PSQ composite system will be of great help to design & fabricate better hybrid waterborne fluorocarbon coatings in the future.

Self‐Lubricative Organic–Inorganic Hybrid Coating with Anti‐Icing and Anti‐Waxing Performances by Grafting Liquid‐Like Polydimethylsiloxane

AbstractPolydimethylsiloxane (PDMS) is one of the most popular materials to protect infrastructures from the complicated environment due to its chemical stability, nontoxicity, low cost, high durability, and chain flexibility. Herein, a series of organic–inorganic hybrid coatings are prepared by simply grafting loop‐like PDMS on a solid surface. Owning to the low surface energy and high mobility of PDMS chains, the special characteristics, including liquid repellency, anti‐fouling, self‐lubrication, anti‐ and delay‐ice, anti‐paraffin, etc., are presented. To confirm the liquid‐like slippery nature of PDMS surface, the controlled de‐icing and de‐waxing tests on rigid chain surfaces are conducted. The liquid‐like nature of PDMS allows ice or paraffin to have a low adhesion in a slip state, but a fractured state on alkylated and perfluorinated surface with a high adhesion strength. In addition, the flexible PDMS chains grafted on the inorganic silica layer by stable covalent bond endow the surface with excellent durability, including maintaining low ice adhesion during 50 icing‐deicing cycles, resistance to UV irradiation, washing or soaking in organic solvent, etc. This work provides a simple approach for constructing self‐lubricative low surface energy coating to realize de‐ice and de‐wax easily, which may have a broad prospect of application in equipment protection.

Flow-Through Atmospheric Pressure-Atomic Layer Deposition Reactor for Thin-Film Deposition in Capillary Columns.

We demonstrate the development of a new atmospheric pressure-atomic layer deposition(AP-ALD) system to coat the inner walls of capillary columns for gas chromatography (GC). Unlike traditional ALD, this reactor operates at near-atmospheric pressure and addresses the challenges of depositing thin films inside capillaries, which include long pump down times, deposition in high-aspect-ratio materials, and temperature control. We show ALD of alumina in 5 and 12 m capillaries (0.53 mm ID) via sequential half reactions of trimethylaluminum and water. Our system yields pinhole-free, uniform thin films. It includes small witness chambers for witness silicon shards before and after the capillary. An engineering flow/transport analysis of the device is provided. Our ALD alumina thin films are characterized by spectroscopic ellipsometry (SE), X-ray photoelectron spectroscopy, transmission electron microscopy (TEM), and energy-dispersive X-ray spectroscopy. Alumina film growth achieved is 1.4-1.5 Å/cycle, which is consistent with previously reported results. Film thickness measurements by SE on witness shards of silicon and by TEM at both ends of the capillary are in good agreement. A capillary column coated with alumina is used to separate different gases by GC, although the retention times of gases are essentially the same as with an untreated fused silica capillary. This successful deposition of ALD alumina in long capillaries opens the door for other possible ALD coatings, including hybrid organic-inorganic coatings, using the 450+ ALD precursors available today.

Enhancement of oxidation and corrosion resistance of flaky carbonyl‑iron powder via SiO2/KH560/PDMS coating applied with sol-gel

The popular magnetic material of flaky carbonyl iron (FCI) is unfortunately vulnerable to electrochemical corrosion when exposed to a salty and foggy environment. This work reports on a sol-gel method that successfully modifies FCI particles, using lithium silicate (Li2SiO3), poly dimethyl siloxane (PDMS), and γ-(2,3-epoxypropoxy) propytrimethoxysilane (KH560), to synthesize Fe@SiO2@KH560@PDMS hybrid composite, related to its organic–inorganic hybrid coatings. The favorable hydrophobicity of organic–inorganic hybrid coatings with the static contact angle of 120° impeded the contact between corrosive medium and FCI core. The results of electrochemical experiments also confirmed its excellent corrosion resistance, since the corrosion potential Ecorr was positively shifted to 0.01 V, and the corrosion current Icorr was three orders of magnitude lower than that of the unmodified FCI particles. Thermogravimetric (TG) analysis indicates that the presence of hybrid coatings also improved the thermal stability of the produced material towards oxidation. Furthermore, the results of molecular dynamics simulation reveal that the hybrid layer inhibits the diffusion of corrosive medium.
