Fomes fomentarius (L.) J. J. Kickx (FF), a fungal hyphae causing tree decay, has confused people for many years on how to deal with it economically and efficiently. In this study, fungal hyphae from FF was first time used as the carbon source to prepare biomass carbon material (BCFF) material via a simple method including carbonization at 600 °C and sodium hydroxide activation. Notably, BCFF-Na4-700-60 (with alkali-carbon ratio of 4:1 and heated at 700 °C for 60 min) showed a large specific surface area (3352 m 2 g −1 ) and a high pore volume (2.29 cm 3 g −1 ). Moreover, the synthetic dye brilliant green (BG) was selected as the dye model to investigate the adsorption performance and mechanism. The maximum adsorption capacity of BCFF-Na4-700-60 was 3166 mg g −1 at pH value of 9, which is superior to those of the great majority of adsorbents. After ten cycles, the adsorption capacity could still be maintained at about 53% of the original value. The results of these studies indicate that biomass carbon materials modified with forest pathogen have excellent adsorption capacity and cycling stability, which could be considered as a potential adsorbent for treatment of wastewater from dyeing industry. More importantly, this rapid and effective method can be further applied to other similar fungal hyphae.

A photoluminescent terbium (Tb) complex involving a novel benzoic-acid compound with a unique coordinated structure, namely 1,4-bis(carbonylmethyl)terephthalate (BCMT), has been designed and synthesized. The new coordinate structure and energy-transfer mechanism between the ligand and Tb(III) ions were investigated in detail. The results demonstrated that the BCMT–Tb(III) complex shows strong fluorescence intensity (4 × 10 6 a.u.) and long fluorescence lifetime (1.302 ms), owing to the favorable degree of energy matching between the triplet excited level of the ligand and the resonant level of Tb(III) ions. Based on the analysis of three-dimensional luminescence spectra , the as-prepared Tb(III) complex can be effectively excited in the range of 250–310 nm, and it shows high color purity, with a bright green appearance.

Zinc oxide/polypyrrole (ZnO/PPy) nanocomposites were fabricated by a in situ polymerization method. The structures of the nanocomposites were analyzed by X-ray diffraction, Fourier transform infrared spectra, thermogravimetric analysis and transmission electron spectroscopy. Then, the capability of ZnO/PPy on the removal of brilliant green from aqueous phase was systematically studied. The ZnO/PPy showed high adsorption capacity toward brilliant green, and a maximum adsorption capacity of 140.8 mg/g at room temperature was achieved. The adsorption kinetics demonstrated a rapid brilliant green uptake by ZnO/PPy, and the experimental data were well fitted to the pseudo-second-order model. The equilibrium data obeyed the Langmuir model. Thermodynamic parameters of \(\Delta {G}^{0}\) and \(\Delta {H}^{0}\) verified the spontaneous and endothermic nature of the brilliant green adsorption onto ZnO/PPy. Furthermore, the regeneration experiments revealed that ZnO/PPy could be reused for at least five times without considerable decrease in their original adsorption capacity, showing potential applications in purification of dyeing effluents.

This study introduces, a titanium dioxide (TiO 2 ) and zerovalent iron (Fe 0 ) nanoparticles immobilized electrospun poly (acrylic acid)/poly (vinyl alcohol) (PAA/PVA) nanofibrous mat for photocatalytic degradation of hazardous water pollutant. For that, PAA/PVA nanofibrous mat was prepared by electrospinning followed by crosslinking and immobilization/incorporation of TiO 2 and Fe 0 nanoparticles through Layer-by-Layer (LbL) self-assembly method. The obtained PAA/PVA–TiO 2 and PAA/PVA–TiO 2 –Fe 0 was fully characterized by scanning electron microscopy (SEM), FTIR, TGA and porosity analysis. The results showed successful immobilization of both (TiO 2 and Fe 0 ) nanoparticles on the nanofibrous mat with uniform distribution. The latter exhibited catalytic activity towards the degradation of Methyl Blue (MB) and Brilliant Green (BG) dyes separately and mixed in the presence of UV light. UV–Vis spectroscopic analysis was used to monitor and quantitative analysis of the degradation. It has been found that high photocatalytic activity of the functional nanofibrous mats has been observed. The fastest conversion rate reached to 99.2% in 20 min at a rate constant of 0.0847/min providing adequate reusability of the nanofiber mats up to four consecutive cycles. A mechanism of the photocatalytic activities has been proposed by referring to the above results. The results opened a promising prospect for using nanofibrous based effective photocatalyst for environmental application.

A series of controllable thermal and pH dual-responsive copolymeric hydrogels (PMA) were prepared by a one-pot reaction with poly(ethylene glycol) methyl ether acrylate (PEGA), 2-methoxyethyl acrylate (MEA) and acroleic acid (AA). The hydrogels exhibited good mechanical properties and a sensitive response to pH and temperature. Besides, the Lower Critical Solution Temperature (LCST) of the hydrogels can be adjusted from 37 °C to 58 °C by changing the content of AA. The hydrogels also showed excellent selective adsorption properties. The maximum adsorption quantity of organic cationic dye brilliant green and methylene blue were 0.49 mg mg−1 and 0.42 mg mg−1 respectively, much better than previous reports. Furthermore, using the thermal and pH responsibility, the PMA hydrogels can release the adsorbed molecules with control. Nearly 95% of carriers could be released at pH 4.01 and 65 °C over 8 h. The regeneration ability makes the materials easy to reuse many times. Due to these properties, these dual-responsive hydrogels have great potential applications in various fields for adsorption, drug delivery, release and tissue engineering.

Light green SF (LGSF), a pervasive dye posing a grave risk to human health, urgently demands the creation of a straightforward, swift, sensitive, intuitive, and recyclable detection method. In this research endeavor, we have innovatively designed a Eu3+@MOF-1 ratiometric fluorescent (RF) probe, utilizing a post-synthetic modification (PSM) approach, for the efficient detection of LGSF in lake water and green-colored beverages. This probe exhibits distinctive fluorescence emission properties, characterized by dual emission peaks at 443 nm and 614 nm. In the presence of LGSF, the emission intensity at 443 nm remains constant, functioning as an internal reference, while the emission intensity at 614 nm decreases progressively. This shift is attributed to the principle of fluorescence resonance energy transfer (FRET), where LGSF effectively quenches the fluorescence of Eu3+@MOF-1 at 614 nm, thereby enabling RF detection of LGSF. Notably, the luminescence color of Eu3+@MOF-1 undergoes a significant change from red to blue upon LGSF addition, which is readily observable by the naked eye. A thorough analysis of the fluorescence quenching mechanism of LGSF on Eu3+@MOF-1 has been conducted. Furthermore, the Eu3+@MOF-1 RF probe exhibits robustness, enduring five testing cycles with a clear transition from red to blue in each iteration, underscoring its high stability and reproducibility. Experimental findings reveal that the Eu3+@MOF-1 RF probe exhibits remarkable specificity, sensitivity, and exceptional regeneration capabilities for LGSF detection. This RF probe offers a potent tool for monitoring water pollution and identifying illicit additions of LGSF in yellow-green beverages, highlighting its broad spectrum of application prospects.

Feline herpesvirus type 1 (FHV-1), a member of the Herpesviridae family, is one of the most important pathogens that causes upper respiratory tract disease in felines. Following infection, FHV-1 can spread retrogradely to the trigeminal ganglia, establishing a life-long latency. Although vaccines are available for routine feline vaccination, FHV-1 is still an agent that poses a serious threat to feline health. There are currently no specific drugs for the treatment of FHV-1. To facilitate the screening of antiviral drugs, we constructed a reporter FHV-1 virus, which expresses a secreted Gaussia luciferase (GLuc) and a bright green fluorescent protein, mNeonGreen. The reporter virus shows slower growth than does the wild-type FHV-1. The expression of the two reporter genes, Gluc and mNeonGreen, was consistent with viral propagation and remained stable during continuous passage in CRFK cells, even after twenty rounds. In addition, the known inhibitor ganciclovir was used to confirm the characteristics of the reporter virus for drug screening. We found that the reporter FHV-1 is suitable for antiviral screening assays. Overall, our work provides a useful tool for screening drugs to combat FHV-1.
