In this study, durable antifogging coatings were fabricated on glass substrates by simply applying a mixture of silica sol and TweenⓇ40. The effects of TweenⓇ40 loading on the properties of the coatings were scrutinized. The coatings demonstrate good antifogging behavior, as no fog or haze was observed on the coated specimen when exposed to hot water steam at 85°C. The optimal coating retains its antifogging property for a notable 12 weeks. The antifogging behavior is mainly provided by TweenⓇ40 within the coating. Meanwhile, the silica sol in the coating serves as a matrix or host for TweenⓇ40, thereby enhancing the coating's robustness.

In this paper, facile synthesis of CaAlSiN 3 :Ce 3+ yellow-emitting phosphors under atmospheric pressure at a moderate temperature and their photoluminescent properties are reported. The prepared CaAlSiN 3 :Ce 3+ phosphors exhibit a broad yellow emission band positioned at 580 nm and covering a bandwidth of 150 nm. The thermal stability of CaAlSiN 3 :Ce 3+ phosphors shows obvious superiority than the commercial YAG: Ce 3+ phosphor, indicating its promising application prospect in power LEDs . In addition, the enhancement of red-light component for CaAlSiN 3 :Ce 3+ phosphor is demonstrated by co-doping Eu 2+ ions. This study offers a facile route to prepare CaAlSiN 3 :Ce 3+ yellow-emitting phosphors, which may be used as a promising candidate for high performance white LEDs .

Bactericidal nanomedicines often suffer from a complicated design and insufficient intrinsic inhibitory efficacy. Herein, novel anti-bacterial copper telluride (CuTe) nano-clusters are reported, featuring superior bactericidal efficiency, facile preparation, and unique mechanism. These nanoparticles, well dispersable in water, resembled grape clusters with rough surfaces. The CuTe nano-grape clusters exhibited ultra-high sterilization efficacy at ultra-low concentration, particularly for Gram-negative bacteria, and were more potent than conventional anti-microbial nanoparticles. Also, the grape clusters effectively inhibited the bacterial biofilm development. Further investigation revealed the synergized mechanisms of reactive oxygen species (ROS) generation and glutathione (GSH) depletion. Interestingly, electron microscopy revealed that the grape clusters served as bacterial hunters by tightly adhering to bacterial surfaces. The bacteria subsequently suffered from the leakage of various intracellular components including nucleic acid, proteins, and potassium. Most encouragingly, CuTe drastically reduced bacterial number in a mouse model with lethal intraperitoneal infection and increased the mouse survival rate to 90%. This finding could inspire the development of highly potent bactericidal inorganic formulations with simplified structure, multiple antibacterial mechanisms, and promising application potential.

Efficient uranium capture from wastewater holds great importance for the environmental remediation and sustainable development of nuclear energy, but it is a tremendous challenge. Herein, a facile and scalable approach is reported to fabricate functionalized hierarchical porous polymers (PPN-3) decorated with high density of phosphate groups for uranium adsorption. The as-constructed hierarchical porous structure could allow rapid diffusion of uranyl ions, while abundant phosphate groups that serve as adsorption sites could provide the high affinity for uranyl. Consequently, PPN-3 shows a high uranium adsorption uptake of 923.06 mg g −1 and reaches adsorption equilibrium within simply 10 min in uranium-spiked aqueous solution. Moreover, PPN-3 affords selective adsorption of uranyl over multiple metal ions and possesses a rapid and high removal rate of U(VI) in real water systems. Furthermore, this study offers direct polymerization strategy for the cost-effective fabrication of phosphate-functionalized porous organic polymers, which may provide promising application potential for uranium extraction.

The achievement of high-efficient pure red emissive carbon dots (CDs) is still a great challenge as well as one of the most critical issues that hinders widespread applications of CDs. Herein, a facile approach for the preparation of high-efficient red emissive CDs (R-CDs) is reported, and they exhibit numerous unique features including pure red emission (λmax ≈ 640 nm), respectable quantum yield (22.9%), low cytotoxicity, two-photon excited fluorescence (TPEF), and high photothermal conversion efficiency (43.9% under irradiation of 671 nm laser). Moreover, the chemical composition and photophysical properties of the R-CDs are detailed characterized and analyzed, and from which their photoluminescence mechanism is proposed. Interestingly, the R-CDs are found to particularly light up RNA-rich nucleolus both in one-photon and two-photon modes as well as show excellent counterstain compatibilities with other classical subcellular dyes. The localization of the R-CDs in nucleolus is supported by ribonuclease digestion testing, and the stronger emission is further verified to be due to an accumulation process. In addition, the R-CDs are confirmed to be facilely conjugated with fluorescein isothiocyanate (FITC) and then bring it into living cells, which reveals their potentials to perform as carriers for delivery of drugs that cannot (or hardly) enter into living cells directly. Finally, the R-CDs are shown to be excellent in photothermal cancer therapy in vitro due to their high photothermal conversion efficiency. This study represents not only a facile method for the preparation of high-efficient R-CDs, but also opens many possibilities for applications, such as in biomedicine (multifunctional theranostic agents) and emitting/display devices, thanks to their unique and superior properties.

We report a facile and eco-friendly strategy for the fabrication of highly fluorescent nitrogen-doped carbon nanodots (N-CDs) and demonstrate their applications for multicolor cellular imaging and Co 2+ sensing in living cells. One-pot hydrothermal method using pigskin as the precursor yields bright green-emitting N-CDs, providing an easy way for the production of N-CDs without a tedious synthetic methodology or the toxic/expensive solvents and starting materials. Doping N heteroatoms benefits the generation of N-CDs with stronger fluorescence emission. As-prepared N-CDs exhibit exceptional advantages including high fluorescent quantum yield (24.1%), excellent biocompatibility, low-toxicity, and satisfactory chemical stability. Depending on these superior properties, as-synthesized N-CDs have been successfully used for multicolor cellular imaging. More strikingly, as-synthesized N-CDs generates strong response to Co 2+ ions and gives rise to the fluorescence quenching and further application is extended to precise and quantitative detection of Co 2+ ions in living cells.

Developing a facile method to fabricate new heterogeneous Metal-Organic Framework (MOFs) based catalysts with high catalytic activity and stability has drawn significant attention. Herein, we demonstrate a simple in-situ pyrolysis reduction strategy to fabricate a novel three-dimensional (3D) Cu-based catalyst, which displays an outstanding performance for the decomposition of 4-nitrophenol (4-NP). Detailed characterization including SEM , FTIR, XPS , ICP-OES, HRTEM , SAED , XRD and BET confirmed the formation of the Cu/C porous composites (Cu/C-PC). Taking advantage of enormous Cu particles in the composite as well as ultrahigh surface area (196.7 m 2 /g) of carbon support, Cu/C-PC presents prominent catalytic activity for the hydrogenation reduction 4-NP to 4-aminophenol (4-AP) with apparent rate constant ( K app ) of 0.0267 s −1 (the ratio of K app to the catalyst amount is 119 s −1 g −1 ), which is dramatically higher than that previous reports. On the contrary, after being washed successively (Cu/C-PC-AW) by FeCl 3 , HCl aqueous solution and deionized water , the Cu/C porous composite materials exhibit fairly weak catalytic activity. The catalytic performance of Cu/C-PC is better than Cu, Cu 2 O and CuO nanoparticles as well as other catalysts in previous reports. Furthermore, Cu/C-PC shows excellent reusability, indicating its potential applications in treatment of water pollution.

Owing to its high capacity of 994 mAh g −1 , low cost, and environmental friendliness , tin (Sn) is considered as an advanced anode material for high-capacity lithium-ion batteries (LIBs). Here, a facile strategy to fabricate core-shell structured Sn@NC composites with one-step and large-scale production is introduced in a liquid-phase reaction under room temperature . When used as anode materials for LIBs, the optimal Sn@NC composite delivers a high reversible discharge capacity of 761.2 and 476 mAh g −1 at a current density of 200 and 1000 mA g −1 after 200 cycles, respectively. A high capacity of 328.3 mAh g −1 can also be obtained even at a current density of 2000 mA g −1 . The excellent cycling stability and rate performance of the composite can be ascribed to the synergistic effect of the nanometer size of Sn powder and porous structure of the carbon shell, both of which can effectively reduce the absolute volume change of electrode during the repeated charge-discharge cycles, and thus lead to excellent electrochemical performances at both rate capability and cycling life.

Immobilized metal affinity chromatography is a green method applied to the separation and purification of proteins and biomolecules in downstream processing. With its unique internal pores, the membrane carriers have more active sites than typical magnetic nanoparticles and beads. It also greatly overcomes the mass-transfer resistance brought by traditional column chromatography. In this study, polysulfone was selected as the pristine membrane. Tannic acid and 3-aminopropyltriethoxysilane coatings were employed to construct the secondary reaction platform, which was then covalently coupled with polyethyleneimine and grafted with iminodiacetic acid groups to chelate Cu 2+ . Bovine serum albumin was utilized as the adsorption protein to adjust and optimize the modification parameters. The results demonstrated that the adsorption amount per unit membrane area reached 0.19 mg/cm 2 under the solution condition of pH 8.5. The adsorption thermodynamics followed the Langmuir model, and the corresponding model parameters were obtained.

A cost-effective and highly efficient electrolyte with a wide electrochemical window, high reversibility of Mg plating/stripping, non-/low-corrosivity, good compatibility with cathode materials, and tolerance of trace water and impurity is crucial for the commercialization of rechargeable magnesium batteries. In this work, a novel boron-centered non-nucleophilic electrolyte that meets all the above requirements is prepared via a facile and economic approach from the raw materials B(TFE)3/MgCl2/CrCl3/Mg (BMCM). The as-prepared BMCM electrolyte is mainly composed of tetracoordinated anions [B(TFE)4]− and solvated cations [Mg2(μ-Cl)2(DME)4]2+. The BMCM electrolyte demonstrates attractive electrochemical performance, with a low overpotential (∼139 mV), a high Coulombic efficiency (∼97%), a high anodic stability (∼3.5 V vs Mg/Mg2+), and a long-term (more than 500 h) cycling stability. Moreover, BMCM shows good compatibility with the CuS cathode material. The CuS|BMCM|Mg full cell delivers a discharge specific capacity of 231 mAh g–1 (at 56 mA g–1), which can retain ∼88% even after 100 cycles. Importantly, the BMCM electrolyte is cost-effective and tolerant of trace impurity and water, which has great potential to be commercialized. This work is expected to promote the development of practical rechargeable magnesium batteries.

A facile and eco-friendly synthetic strategy has been developed to achieve a series of hydrogen bonding-rich bio-based thermosetting resins in this study. Using both safe and green solvents, we successfully synthesized target bio-based bisbenzoxazines (DcTa-fa, DcTa-sa, and DcTa-da) with high purity from five different naturally resourced raw materials. The chemical structures of the obtained bisbenzoxazine monomers were verified by nuclear magnetic resonance technology (including 1H and 13C NMR, two-dimensional 1H–1H nuclear Overhauser effect spectroscopy (NOESY), and 1H–13C heteronuclear multiple quantum coherence (HMQC)) and Fourier transform infrared spectroscopy (FT-IR). The polymerization processes were systematically investigated by differential scanning calorimetry (DSC) and in situ FT-IR analysis. Contact angle measurements were conducted and the corresponding results revealed tunable surface properties during the polymerization process of each bio-based bisbenzoxazine resin. In order to understand the relationship between the chemical structure and surface properties, more detailed FT-IR analyses were carried out to investigate the hydrogen bonding networks in the resulting polybenzoxazines. Notably, poly(DcTa-fa) presented excellent thermal stability (Td10 of 377 °C, Yc of 53.7 wt%) and strong adhesion strength (5.232 ± 0.26 MPa), while poly(DcTa-sa) and poly(DcTa-da) showed outstanding surface properties with very low surface free energy values (22.91 and 22.84 mJ m−2). These results highlight the utility of smart and sustainable benzoxazine chemistry and offer a facile and green synthetic approach to access hydrogen bonding-rich bio-based benzoxazine resins with many attractive properties.

A simple and effective synthesis of 3,4-dihydropyrimidin-2(1H)-ones/thiones and their derivatives from aldehydes, β-dicarbonyl compounds and urea or thiourea using D-xylonic acid both as a green solvent and an effective catalyst is described. Taking the environment and economy into account, the work presented here has the merits of environmental friendliness, easy operation, simple work-up, excellent yields and the avoidance of organic solvents and inexpensive catalysts. In addition, the good properties of D-xylonic acid have also been validated by the synthesis of 5-phenyl-1(4-methoxyphenyl)-3[(4-methoxyphenyl)-amino]-1H-pyrrol-2(5H)-one and 12-phenyl-9,9-dimethyl-8,9,10,12-tetrahydrobenzo[a]xanthen-11-one. The synthesized compounds were characterized by FT-IR, 1H NMR, 13C NMR and melting point.
