Inorganic/polymer hybrid hydrogels generally exhibit excellent mechanical properties, while extra function include luminescence are extremely explored due to the further application in sensors and optoelectronic devices. Herein, we report the rare-earth (RE) complex/silica nanoparticles
(SNs) luminescent hybrid polyethylene glycol (PEG) hydrogels showing stable luminescence. The hybrid hydrogels coordinated with RE (Eu3+) complex are fabricated via a convenient in situ photocrosslinked procedure. The coordination polymers showed red luminescent color under
the 365 nm UV irradiation. Furthermore, the hybrid hydrogel exhibited long luminescence lifetime. These properties of hybrid luminescent hydrogel gave rise to a great improvement in the potential applications as a soft material.

Mesoporous manganese dioxide(meso-MnO2) fibers were synthesized in high yields in a simple, templatefree manner by localized Ostwald ripening under hydrothermal conditions. The adsorption behavior of 2,4-dinitrophenol on meso-MnO2 fibers was well described by Langmuir
isotherm equation, Dubinin-Radushkevich and pseudo-second-order kinetic equation, so the adsorption mechanism maybe a chemical and monolayer adsorption. Meso-MnO2 fibers have potential for use as a high-performance adsorbent.

Herein, we report the hydrothermal synthesis and detailed characterization of fluorine-doped calcium silicate hydrate (F-CSH). The synthesized material were characterized by several techniques, i.e., X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform
infrared (FTIR) spectroscopy. The detailed studied revealed that the sodium fluoride was beneficial to promote the growth of gyrolite but prevent the formation of plate-like 14 Å tobermorite. The produced CaF2 affects the appearance and shape of the material. The XRD results
confirmed that the constitution and structure of CSH are different from those of F-CSH which can generate the phase of gyrolite. Finally, the modification mechanism of F-CSH was primarily analyzed and discussed in this paper. This research is of great significance in the preparation and characterization
of various fluorine-doped inorganic compounds.

Sericin has shown a great potential as a biomaterial in biomedical application due to its good hydrophilicity, reactivity and biodegradability. To solve the adherence and growth of microorganisms on sericin gel, here we prepared a polyelectrolyte film with interactive arrangement of
opposite charges poly(dimethyldiallylammonium chloride) (PDDA) and poly(acrylic acid) (PAA) coated on the surface of sericin gel via electrostatic interaction. AgNPs was then synthesized with the assistance of UV in situ on the polyelectrolyte film to endow the antibacterial
activity of sericin gel. SEM revealed the polyelectrolyte film could effectively facilitate the high density growth of AgNPs as a 3-D matrix and the modification of polyelectrolyte and AgNPs did not alter the porous characteristics of sericin gel. XRD studies suggested AgNPs synthesized on
the polyelectrolytes film coated sericin gel had good crystal structure. DSC analysis showed AgNPs could tightly bind with the polyelectrolytes film and sericin gel, and the binding may improve the melting temperature of AgNPs. Both bacterial inhibition zone and growth curve assay demonstrated
the sericin gel coated with AgNPs-polyelectrolytes film had an excellent and long-lasting antibacterial activity. This novel sericin gel has shown great potentials in biomedical application such as wound healing.

Natural cotton fiber used for reinforcement is low-cost, environmentally friendly, good flexibility and easy to obtain. In this study, a new cotton fiber/silica aerogel composite was developed by sol–gel method via freezedrying. The obtained composite has excellent flexibility
and can be restored to its original state after bending for 180° without obvious cracks. After 20 cycles continuous compression, the total unrecoverable strain loss is only 20% under strain of 60%. The composite also shows very prominent hydrophobicity, and the contact angle with water
reaches 145 degrees. It has strong adsorption capacity for organic reagents and oil, with adsorption ratios of 500% and 600%, respectively. In addition, the composite has a low thermal conductivity of 0.038 W/(m·K) at room temperature. The obtained composite exhibits considerable promise
in oil-water separation and thermal insulation.

Polyethyleneimine (PEI) modified PluronicF127 block copolymers (PEI-F127-PEI) were synthesized via a chemical reaction of isocyanate and hydroxyl group. By using PEI-F127-PEI block copolymers as templates combined with a sol–gel process, followed by evaporation-driven assembly
and calcination process, mesoporous TiO2 nanomaterials with different phase composition (rutile, anatase/rutile mixture, and anatase) and morphology were prepared. The prepared TiO2 samples were characterized by transmission electron microscopy (TEM), X-ray diffraction
(XRD), UV–vis diffuse reflectance spectrophotometry and N2 adsorption analysis. It is found that the mass ratio of TiCl4/PEI-F127-PEI and calcination temperature have an important influence on the phase composition and morphology of TiO2. Compared to
reported values, the transformation temperature from anatase to rutile decrease. When the mass ratio of TiCl4/PEI-F127-PEI is 2.0/1, the prepared sample exhibits the highest photocatalytic activity for the degradation of methylene blue (MB) under UV light irradiation, indicating
that the mixed anatase/rutile phase TiO2 is an efficient photodegradation catalyst of MB pollutant in wastewater treatment.

In this paper, metal–organic frameworks (MOFs) are applied to get rid of Congo red from effluent in an inexpensive and effective manner. Co-containing MOFs (Co-MOF) were prepared via solvothermal treatment, and their structures were tested by performing SEM, TG, and XRD. The MOFs
were studied for the removal of CR from wastewater, and the kinetics of the adsorption process were investigated. The results indicated that the pseudo second-order kinetic model properly describes the removal of CR and the maximum adsorption capacity within 5 h is 355.2 mg/g for Co-MOF. The
adsorption capacity of the MOFs was evaluated under different pH conditions. This work highlights the broad application prospect of MOFs in sewage disposal.

Horseradish peroxidase (HRP) was successfully immobilized on a novel enzyme carrier, hydride composite of graphene oxide grafted sodium styrene sulfonate (GO-g-PSStNa), and used for removal of phenol from water. Hydride composite (GO-g-PSStNa) was synthesized using graphene
oxide (GO) and sodium styrene sulfonate (SStNa) by atom transfer radical polymerization (ATRP). The morphologies and chemical composition of the resulted samples were investigated by SEM, FTIR and XPS. The results showed that the hydrophilic monomer SStNa was grafted onto the surface of the
GO. HRP was immobilized on the surface of hydride material and its loading reached 8.0 mg/g under the immobilization conditions of pH 7 at 0 °C. The removal efficiency of phenol for immobilized HRP had an optimum pH 6, which was shifted to 8 for free enzyme. Both the free and immobilized
enzyme shared the same optimal temperature at 40 °C. Immobilized HRP exhibited higher removal efficiency for phenol compared with free HRP. The best immobilization effect could be reused at least eight times. The high phenol removal can be resulted by improvement of catalytic activity
of immobilized HPR with adsorption on GO-g-PSStNa support.

Due to the special surface wettability, self-cleaning, drag reduction, anti-icing and other properties, superhydrophobic materials are widely used as coating or coating additive on the surface of building materials, ships, and even for liquid transportation, biomedicine, etc., which
have become one of the research hotspots in the direction of coating in recent years. However, the hydrophobic surface itself has weak stability and poor durability, which affects its application value. Therefore, in this study, PS nano-microcapsule was prepared by the multiphase emulsion
method, and their particle size was measured by SEM electron microscopy to be about 350–550 nm, with a relatively uniform distribution. The hydrophobicity of PS nano-microcapsule modified with trimethoxy (1H, 1H, 2H, 2H-trifluoroctyl) silane (PFOTMS) at different molar ratios was investigated.
SEM results showed that the surface roughness of the modified PFOTMS-PS nano-microcapsule could be changed. The contact angle proved that the greater the content of PFOTMS, the better the hydrophobicity of the modified PFOTMS-PS nano-microcapsule. When the content reached 50%, the hydrophobic
performance was the best. As a coating, PFOTMS-PS nano-microcapsule has no specific requirement for the properties of the substrate material. It should be noted that the hydrophobicity of the coating did not change significantly after 30 days at room temperature. The above results indicated
that PFOTMS-PS nano-microcapsule had good hydrophobicity and stability, and is expected to be used in many fields such as waterproof textiles and architectural coatings in the future.

Hybrids MIL-53/GO and MIL-101/GO were synthesized and were applied for the drug delivery. The adsorption for IBU (ibuprofen) on MOFs/GO and MOFs were compared and it was found that the addition of GO enhanced IBU loading and stability. The drug release experiments of IBU loaded MOFs
and MOFs/GO were conducted, and it was found that drug release of MOFs/GO was slower, which can be explained for the hydrogen bonding between GO and IBU. It also exposed that the IBU loading of MIL-101 (Cr) and MIL-101/GO were both larger than that of MIL-53 (Fe) and MIL-53/GO, meaning that
metal ions had an effect on the pore size which will effect on the selectivity on the adsorption for different drug molecules. Drug carrier can be designed according to different size drug molecules through the formation of MOFs/GO with optimal metal ions.

Barium titanate (BaTiO3) nanopowders with various morphologies and crystallinities were successfully prepared by three methods. For each of them, the sintering kinetics of the BaTiO3 ceramics tuned by morphology were correlated to exposed crystal facets, crystallinity,
interface curvature and particle size distribution. A highly crystalline particle with flat interface results in a low sintering driving force, and the grain growth proceeds along predetermined growth direction. By contrast, spherical particles with small curvature radius and low crystallinity
possess a high sintering driving force, and growth occurs rapidly in all directions. In this latter case, the resulting ceramic presents a large shrinkage and the highest rate of densification. Small particle size with homogeneous size distribution contributes to the ceramic sintering as well.
The understanding of the morphology tuned sintering kinetic of BaTiO3 ceramics provides a basis for the fabrication of BaTiO3 transparent ferroelectric ceramics in the future.
