This work presents a molecular-to-structural strategy for fabricating high-performance CL-20-based composite energetic materials using direct ink writing (DIW). A poly(vinyl alcohol)/poly(acrylic acid)/modified potassium titanate whisker (PVA/PAA/ M-PTW) interpenetrating polymer network (IPN) was designed to simultaneously enhance mechanical strength and reduce mechanical sensitivity. The hydrogen bonding–covalent crosslinking–filler reinforcement mechanism ensured uniform dispersion of CL-20 crystals and strong interfacial adhesion within the polymer matrix. Surface modification of PTW with 5 wt% KH-550 improved compatibility with the IPN, yielding printed structures with excellent form accuracy and adhesion to aluminum substrates (0.961 MPa). The optimized composite exhibited high compressive strength (16.77 MPa) and reduced impact and friction sensitivities compared with ε-CL-20 and submicron CL-20 samples. It achieved stable detonation wave transmission within a 90°-160° corner range in a 1.2 × 1.2mm charge slot, with the critical detonation size reaching 0.3m × 0.3mm. The measured detonation velocity of 7267.9m/s (83.2% of theoretical). These results demonstrate that the DIW-based PVA/PAA/M-PTW system enables the precise construction of high-strength, low-sensitivity energetic composites with reliable detonation performance, providing a promising pathway for advanced micro-scale energetic devices.

Background Q235 steel is susceptible to severe corrosion during the pickling process, especially in hydrochloric acid media, which not only shortens the service life of the equipment, but also may cause safety hazards and environmental pollution. Methods : A bis-triazole Schiff base carboxylic acid (BTSCA) was synthesized, named the 5-((4-(4H-1,2,4-triazol-4-yl) benzylidene) amino)-1H-1,2,4-triazole-3-carboxylic acid. The present study investigates the inhibitory performance of Q235 steel in a 1 M HCl solution containing BTSCA. The experimental methods adopted were weight loss method and electrochemical method. Significant findings : The results show that BTSCA has a good inhibitory efficiency on Q235 steel in 1 M HCl solution, which can reach 98.98%. Kinetic and thermodynamic analyses explained inhibitory mechanism of the compound, and the results showed that the adsorption behavior was in accordance with the Langmuir isotherm. The surface morphology of Q235 steel was characterized by scanning electron microscope (SEM) and atomic force microscope (AFM). Density functional theory (DFT) was used to analyze the inhibitory mechanism of BTSCA. Combined with molecular dynamics simulation (MD), the most stable configuration, adsorption sites and adsorption energy of BTSCA on the steel surface were determined.

Abstract Current birefringent crystals (e.g., MgF2, α-BBO, and YVO4) are limited by either small birefringence or insufficient deep-UV transparency. Achieving both properties simultaneously remains a key challenge. To address this issue, recent research based on the “confined π-conjugated” strategy has turned its attention to fluoroaluminoborates. In this structural design, non-π-conjugated [Al−O/F] units connect and isolate planar π-conjugated groups, effectively broadening the bandgap while maintaining optical anisotropy. Building on this concept and incorporating different cations, this study reports two new fluoroaluminoborate compounds: CaAlB3O6F2 (CABOF) and its isostructural analogue, PbAlB3O6F2 (PABOF). In PABOF, the introduction of Pb2+ induces local structural distortion, thereby enhancing the optical anisotropy. Both CABOF and PABOF exhibit birefringence values exceeding 0.1 at 546 nm, with PABOF demonstrating the largest birefringence among the known fluoroaluminoborates. In addition, both compounds exhibit excellent thermal stability. This work identifies two potential UV-birefringent materials, further enriching the fluoroaluminoborate family.

Poly( m -xylylene adipamide)/poly(ethylene terephthalate) (MXD6/PET) copolymers are synthesized by melt copolycondensation with 1–5 wt% low molecular weight PET oligomers into the MXD6 oligomers at 260 °C. FR-IR and 1 H NMR analysis results indicate that the interchange reaction has occurred between MXD6 oligomers and PET oligomers. The thermal behavior of copolymers shows that the melting temperature of MXD6/PET copolymers decreases with the increasing of amount of PET oligomers, while the crystallization temperature accordingly increases. And the equilibrium temperature T m 0 is evaluated to be 251.8 °C for the copolymers with 5 wt% PET oligomer adding, which is very close to that of neat MXD6. The tensile and impact strength of MXD6/PET copolymers are significantly improved than that of pure MXD6 by mechanical properties test, and the microfibril structure in the impact fracture sample's surface reveals the feature of ductile fracture.

Near-infrared (NIR) phosphors as crucial components of NIR light sources have multifunctional and smart spectroscopy applications, prompting an increasing research interest in developing efficient and stable NIR materials. Focusing on this issue, the present study explored the luminescent properties of Cr 3+ -doped Ca 3 ZnMGe 3 O 12 (M = Zr, Hf, Sn and Ti) garnet family. These materials exhibit an emission peak falls within the range of 785–805 nm with a full width at half maximum (FWHM) varying from 114 to 123 nm. Among them, the Ca 3 ZnZrGe 3 O 12 :Cr 3+ phosphor shows the highest photoluminescence quantum yield (PLQY = 60.3 %) and an excellent thermal stability ( I 423K / I 298K = 77.51 %). Moreover, the performance of a prototype Ca 3 ZnZrGe 3 O 12 :Cr 3+ -containing NIR pc-LED device was estimated, which achieves an NIR output of 23.46 mW and a photonic efficiency of 14.09 % under 100 mA driving current. Non-destructive examination can be realized using this light source, demonstrating the good potential of the material in NIR spectroscopy applications.

Herein, we successfully synthesized two novel metal thiophosphites (MTPs) hybridized with carbon, that is, NiPS3/C and SnPS3/C composites, via an environment-friendly and cost-effective approach without harsh reaction conditions. Subsequently, the electrochemical performances of NiPS3/C and SnPS3/C composites have been investigated in coin-cells, and it is revealed that MTPs/C have a significantly higher Li-storage capacity and better stability compared to the MTPs without carbon. Moreover, the SnPS3/C electrode shows a lower internal resistance and a better rate performance compared to NiPS3/C. We employed extensive ex situ experiments to characterize the materials and interpreted the remarkably improved performance of MTPs/C.

Ruddlesden–Popper (RP)-structured materials based on transition metals with a variable valence, such as Fe, Mn, Ni, and so on, have been well documented for their potential of being used as electrodes in solid-oxide fuel cells. However, RP materials with pure or dominant ionic conduction are rare. Here, a series of Zr-based RP materials Sr3Zr2–xMxO7–0.5x (M = Ga, Y, In) with electrical conductivity as high as 3.25 × 10–3 S cm–1 at 900 °C in air was reported, which represents the highest conductivity for the Zr-based RP materials and is comparable to that of the recently reported In-based RP oxide-ion conductors, such as NdBaInO4-based and La2BaIn2O7-based materials. Under low oxygen partial pressure (pO2), the doped samples show pure ionic conducting behaviors without n-type electronic conductivity. The defect formation energies, local structure around the oxygen vacancies, and oxide-ion-conducting mechanism of the acceptor-doped Sr3Zr2O7-based materials were studied for the first time. The results revealed a two-dimensional oxide ion migration characteristic within the perovskite slabs. This work therefore provides a good reference for developing new oxide-ion conductors in the Zr-based RP-structured materials.

BACKGROUND A shelf-life that is too short is the main problem with strawberries. Nano-TiO 2 can catalyze and oxidize ethylene under ultraviolet (UV) light irradiation to eliminate its ripening effect on fruits and prolong the freshness period. RESULTS In this work, nano-TiO 2 modified by methacryloxy propyl trimethoxyl silane (KH570) was blended with low-density polyethylene (LDPE) to prepare modified atmosphere packaging (MAP), and the influence of TiO 2 content on films was analyzed before and after UV treatment. The results show that the modified nano-TiO 2 (M-TiO 2 ) can be uniformly distributed in LDPE, improving its mechanical strength, hydrophobicity, oxygen barrier and UV shielding properties. A modified atmosphere with low ethylene, low O 2 and high CO 2 can be created to inhibit the ripening and spoilage of strawberries. The weight loss rate of fruit can be effectively reduced. The tendency of fruit firmness decline and nutrient loss can be slowed and stabilized, contributing to controllable shelf-life. Excellent freshness preservation function can be realized without special UV treatment. CONCLUSION Since UV treatment is rare in actual storage and transportation, LDPE/M-TiO 2 composite film has practical value as MAP for strawberry and similar non-climacteric fruits. © 2022 Society of Chemical Industry.

The increasing complexity of environmental pollution posed a higher requirement for the development of environment-governed functional materials . Herein, to achieve desired synergy and multiple functionalities of eco-friendly nanomaterials , a micelle-mediated metal assembly strategy was proposed to integrate plasmonic Ag nanoparticles into MnO x modified mesoporous silica hosts by metal-modified neutral dodecyl amine surfactant , correspondingly, a multifunctional mesoporous Ag@MnOx/m-SiO 2 (AMSs) nanocomposite was obtained. The characterization results revealed that the introduction of Mn and alteration in the amount of Ag mediated the formation of a special mesostructure and nanometric morphology of the silica host. Bearing a low Ag loading (r.t. of Ag/Mn = 1/2), ultrafine Ag nanoparticles were embedded in the inner core of mesoporous silica nanospheres . While assembly with a higher Ag concentration affected the morphology of the obtained AMSs and resulted in rich Ag nanoparticles on the exterior surface of mesoporous silica. By this strategy, ultrafine Ag nanoparticles and well-dispersed amorphous MnO x species were coupled into the mesoporous silica to reach a special configuration and integrated functionality. The obtained AMSs-3 can effectively inactivate bacteria ( E. coli , S. aureus, and P. aeruginosa ) with a prolonged inhibitory effect, rapidly reduce harmful nitrophenol, as well as photothermally assist water evaporation (evaporation rate of 1.51 kg m −2 h −1 , receiver efficiency of 87%). This work provides versatile environment-governing functional nanomaterials for both highly effective antimicrobial and environmental remediation.

The Bi 2 MO 4 Cl (M = Gd and Nd) nanosheets were prepared by a molten salt flux method for the first time. The resulted Bi 2 GdO 4 Cl (F-BG) nanosheets showed the highest photocatalytic activity for oxygen (O 2 ) evolution and trypan blue (TB) degradation than Bi 2 NdO 4 Cl (F-BN), Bi 2 GdO 4 Cl (S-BG) and Bi 2 NdO 4 Cl (S-BN) synthesized by a solid-state method. The F-BG nanosheets showed the larger specific surface areas and abundant pores, which could provide more reactive sites. The photoelectrochemical and photoluminescence (PL) results revealed that F-BG sample had the excellent separation and transfer rates of photogenerated charge carriers, leading to the highly photocatalytic performance for both O 2 evolution and TB degradation. The UV–Vis diffuse reflectance spectra (DRS) showed all samples had the visible-light-responsive characteristic. The radical trapping experiment revealed hole (h + ) played a major role, while superoxide radical ( \(\cdot {\text{O}}_{{2}}^{ - }\) ) contributed a little to photocatalytic degradation process. Thus, a possible photocatalytic mechanism was proposed based on the radical trapping experiment. This work shows us a useful insight into the preparation of highly active bismuth-based oxyhalide nanosheets photocatalysts by a molten salt synthesis through surface modification and morphology control and provides the possibility of water splitting under visible light.

Ru(II) complexes have attracted increasing attention as promising antitumor agents for their relatively low toxicity, high affinity to DNA molecules, and correlation with multiple targets. Meanwhile, quinolones are synthetic antibacterial agents widely used in the clinical practice. In this paper, two novel Ru(II) complexes coordinated by levofloxacin (LOFLX), [Ru(bpy)2(LOFLX)]·2ClO4 (1), and [Ru(dmbpy)2(LOFLX)]·2ClO4 (2) (bpy = 2,2′-bipyridine, dmbpy = 4,4′-dimethyl-2,2′-bipyridine) were synthesized with high efficiency under microwave irradiation and characterized by ESI-MS, 1H NMR, and 13C NMR. The binding behavior of these complexes with double-strand calf thymus DNA(CT-DNA) was investigated using spectroscopy, molecular docking, and density functional theory calculations. Results showed that 2 exhibited higher binding affinity than 1 and LOFLX. Further studies showed that 2 could induce the G2/M phase arrest of A549 cells via DNA damage. In summary, these results indicated that 2 could be developed as a potential anticancer agent in treatment of lung cancer through the induction of cell cycle arrest at G2/M phase by triggering DNA damage.

Titanium carbides (MXenes) are promising multifunctional materials. However, the negative surface charge and layer-by-layer restacking of MXenes severely restrict their application in the field of anionic pollutants, including in hexavalent chromium (Cr(VI)). Herein, Ti3C2TxMXenes was functionalized through in situ polymerization and intercalation of poly(m-phenylenediamine) (PmPD), then Ti3C2Tx/PmPD composites were obtained. Delightedly, Ti3C2Tx/PmPD composites exhibited positive surface charge, expanded interlayer spacing, and enhanced hydrophobicity. Furthermore, the specific surface area of Ti3C2Tx/PmPD composite was five and 23 times that of Ti3C2Txand PmPD, respectively. These advantages endowed Ti3C2Tx/PmPD composite with an excellent adsorption capacity of Cr(VI) (540.47 mg g−1), which was superior to PmPD (384.73 mg g−1), Ti3C2TxMXene (137.45 mg g−1), and the reported MXene-based adsorbents. The Cr(VI) removal mechanism mainly involved electrostatic adsorption, reduction, and chelation interaction. This study developed a simple functionalization strategy, which would greatly explore the potential of MXenes in the field of anionic pollutants.Keywords:titanium carbides;functionalization;polymerization;hexavalent chromium;adsorption
