Chemical vapour deposition (CVD) rates are limited, making the preparation of thick diamonds challenging. We propose an efficient high pressure high temperature (HPHT) welding method for polycrystalline CVD diamond films. Multiple layers of CVD polycrystalline diamond films are welded into a monolithic structure under 15 GPa and 2100 °C. HPHT treated samples have an extremely high bond strength and the hardness of the weld layer exceeds 120 GPa. Microstructural analyses suggest the mechanism of HPHT welding: laser treatment transforms the carbon atoms on the CVD diamond film surface from SP3 to SP2 hybridization, forming a non-diamond-carbon/diamond coherent interface. Under HPHT conditions, the carbon atoms are again transformed from SP2 to SP3 hybridization, forming a strong interlayer bond through diffusion at the coherent interface. This method provides a new approach for rapidly preparing diamond bulk materials.

Two-dimensional (2D) organic–inorganic hybrid layered perovskites have attracted increasing attention as promising candidates in optoelectronics, due to their excellent physical attributes. However, although great efforts have been made, broadband white-light emission with a high color rendering index based on 2D hybrid perovskites still remains rare. Here, we report a broadband white-light emissive 2D organic–inorganic hybrid (110)-oriented perovskite, N-(3-aminopropyl)imidazole tetrachloro-lead (1), in which the 2D corrugated layered inorganic framework is formed by corner-shared highly distorted lead chloride octahedra. Remarkably, the color rendering index of 1 is up to 93, which is superior to that of previously reported broadband white-light emission in 2D organic–inorganic hybrid perovskites. Such a 2D hybrid layered perovskite material with a high color rendering index may provide potential applications in white light-emitting diodes.

Optically active hybrid particles consisting of chiral organic component and inorganic component integrate the individual advantages of the components in one entity. This article reports a new type of optically active hybrid particles constructed by helical substituted polyacetylene and octavinyl polyhedral oligomeric silsesquioxane (OvPOSS). The hybrid particles were prepared in a two-step process. First, helical substituted polyacetylene with pendent vinyl groups was synthesized and named as macromonomer (MM). Then, hybrid particles were prepared from MM and OvPOSS by free radical suspension polymerization, in which OvPOSS acted simultaneously as comonomer and crosslinking agent. OvPOSS and MM together constituted a crosslinked network and formed spherical, porous hybrid particles. The resulting hybrid particles exhibited the desired optical activity, according to circular dichroism spectroscopy measurement. As an organic/inorganic hybrid molecule itself, OvPOSS moderately improved the thermostability of the organic component and meanwhile increased the porosity of the hybrid particles. It also helped to tune the surface morphology of the hybrid particles. The present study provides a novel class of optically active hybrid particles, and the preparation strategy may further work as a versatile platform for developing novel chiral hybrid materials.

Abstract Amphiphilic globular protein–polymer hybrids, consisting of poly(methyl methacrylate) (PMMA) as hydrophobic tail and globular protein as hydrophilic head, are prepared by the end-functional PMMA covalently binding to the primary amino groups of bovine serum albumin (BSA) in the phosphate buffer saline (PBS)/acetone mixture solvents at pH 5. The self-assembly behaviors of amphiphilic BSA–PMMA hybrids are explored in aqueous solution by the dynamic light scatter (DLS), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The self-assembled morphologies of the amphiphilic BSA–PMMA hybrids are controlled by the length of hydrophobic PMMA chains. The amphiphilic BSA–PMMA hybrids with the longer hydrophobic PMMA chains self-assembled into spherical vesicles and elongated tubular vesicles, and conversely, they self-assembled into micelles. A vesicle consists of BSA as two outer hydrophilic layers and PMMA as hydrophobic wall. Graphical Abstract Amphiphilic globular protein–polymer hybrids consist of PMMA as hydrophobic tail and globular protein BSA as hydrophilic head. Amphiphilic globular protein–polymer hybrids self-assembled into micelles or vesicles in phosphate buffer saline. The self-assembled morphology of amphiphilic protein–polymer hybrids was controlled by adjusting the length of hydrophobic chains.

Sepiolite can form stable hybrid pigments by immobilizing organic dyes in its microporous structure. Previous investigations demonstrated that the micropores and coordinated water might be responsible for the exceptional color and stability of indigo-sepiolite hybrid pigments. This work reveals the roles of coordinated water in forming hybrid pigments by acid modification. Raw sepiolite was modified by nitric acid at different conditions before use. Then a series of indigo-sepiolite pigments were prepared by indigo and acid-modified sepiolite. Their microstructures were characterized and analyzed by X-ray diffraction, Fourier transform infrared, transmission electron microscopy , and N 2 adsorption-desorption. The color properties of hybrid pigments were evaluated by reflectance spectra and CIE color parameters. Investigations into the chemical stability of pigments were conducted using concentrated HNO 3 and dimethyl sulfoxide. In addition, the photostability of pigments exposed to simulated 30-year illumination in a typical museum was studied. Acid modification of sepiolite contributed to a larger specific surface area and pore volume. However, acid modification resulted in worse color properties and stability due to the removal of coordinated water bonded with octahedral Mg 2+ . These findings confirmed that coordinated water molecules were the key to stabilizing indigo-sepiolite hybrid pigments by forming hydrogen bonds .

Nitrogen dioxide (NO2) is a significant environmental and human health hazard. Current NO2 sensors often lack sensitivity and selectivity under ambient conditions. This study investigates ammonia pyrolysis modification of monolayer Ti3C2Tx MXene to enhance NO2 detection at room temperature. Nitrogen-doped Ti3C2Tx demonstrates a substantial improvement in sensitivity, with a response of 8.87% to 50 ppm of NO2 compared to 0.65% for the original sensor, representing a 13.8-fold increase. The nitrogen-doped sensor also exhibits superior selectivity and linearity for NO2 under ambient conditions. Theoretical analysis shows that nitrogen incorporation promotes enhanced interaction between Ti3C2Tx and its surface oxygen-containing functional groups through electronic hybridization, resulting in improved adsorption energy (1.80 |eV|) and electron transfer efficiency (0.67 |e|) for NO2, thereby enhancing its gas-sensing performance. This study highlights the potential of ammonia pyrolysis-treated Ti3C2Tx MXene for advancing NO2 sensor technologies with heightened performance at room temperature.

A novel silylated ligand (L–Si) derived from a derivative of phenanthroline (2-(2-hydroxyphenyl)-imidazo[4,5-f]-1,10-phenanthroline, denoted as L) was designed, and it played key roles in the assembly of new organic-inorganic mesoporous hybrid functional material. Firstly, the two N atoms of pyridine rings can coordinate to europium ions and sensitize its luminescence. Secondly, the NH of imidzole ring could form hydrogen bonds with fluoride anions. Thirdly, the silylated group can covalently bonded to the frame of SBA-15 mesoporous silica via in-situ synthesis approach. In addition, 2-thenoyltrifluoroacetonate (TTA) was selected as the second ligand for the purpose of better luminescence. Finally, the europium luminescent mesoporous hybrid material Eu(L–S15) 2 TTA was obtained through the coordination reaction between europium ion and L–S15 as well as the second ligand TTA. Eu(L–S15) 2 TTA not only exhibits excellent luminescent properties and high thermal stability, but also retains the ordered mesoporous structures. More importantly, it displays a high-sensitivity sensing function with respect to fluoride ion. The limit of detection for the fluoride ion is as low as 1.6 × 10 −9 M for the fluoride ion.

Intercalation pseudocapacitance is the key point to achieving the balance between the volumetric capacitance and the rate performance of energy storage. However, the low pseudocapacitive reactivity of the active center still limits the energy density of the pseudocapacitance devices. Herein, we propose a strategy that regulates the p - d hybridization of confined MXene via the co-doping of B and O atoms (BO-MXene) for outstanding electrochemical performance. Both experiments and density functional theory (DFT) reveal that the inner doped O atoms in low 2 p orbital energy strengthen the hybridization of Ti and electron-deficient B in MXene for high retention of B atoms, weaken the Ti-O covalency in MXene. As a result, the weakened p - d hybridization of Ti and O for the outer surface and strengthened p - d hybridization of Ti and B for the inner, promote the adsorption of protons and electron transfer, respectively. Further, the BO-MXene-based hybrid supercapacitors achieve a significant volumetric energy density of 56.86 Wh L -1 at 25.6 kW L -1 . This electronic structure via tuning the p - d hybridization in MXene proposes a new path for designing proton-confined intercalation pseudocapacitance.

The combination of photothermal therapy (PTT) and reactive oxygen species (ROS)-involved photodynamic therapy (PDT) holds great promise in enhancing anticancer effect. Herein, a MoS 2 -based multifunctional biomimetic nanotherapeutic platform for synergistic PTT and PDT anti-tumor therapy and real-time self-evaluation of therapeutic effect was developed. MoS 2 hollow nanospheres and fluorescence TAPP-Ma was cloaked with a 4T1 cell-activated fibroblast cell (CM-AF) hybrid membrane to give nanosystem CM-AF-MoS 2 @TAPP-Ma. The hybrid membrane as a delivery system not only offers the nanotherapeutic platform with homotypic targeting ability, but also effectively eliminates the barrier effect of tumor tissue microenvironment. Caspase 3 (Casp3) inside cancer cells activated by the PTT effect of MoS 2 hollow nanospheres broken down TAPP-Ma, triggering the PDT of TAPP. At the same time, the fluoresce “turn-off” of TAPP-Ma provided the base for the self-evaluation of therapeutic effect. The in vitro and in vivo outcomes suggested that the MoS 2 -based multifunctional biomimetic nanotherapeutic platform exhibited synergistic cascade effect for cancer therapy, making it an promising anti-cancer candidate in biomedical clinical application.
