Laser-induced graphene (LIG) has garnered significant attention for its cost-effectiveness and high efficiency in fabricating flexible micro-energy storage devices. In this study, we devised a simple method to fabricate double layer P-doped LIG electrodes through repetitive laser induction technology for high-performance flexible energy storage applications. Instead of utilizing commercial polyimide (PI) thin film, we optimized the formation process of P-doped PI thin film and achieved a highly flexible double layer P-doped LIG thin film electrode with a uniformly porous structure and the high porosity through repeated laser induction processes. Experimental results demonstrated that the developed double layer P-doped LIG thin film electrode exhibits high porosity, high specific areal capacitance of 180 mF cm −2 , and high energy density of 0.025 mWh cm −2 . Furthermore, an all-solid-state micro-supercapacitor utilizing hydrogel electrolyte was assembled, demonstrating a high areal capacitance of 62 mF cm −2 and excellent cycling stability with 95% capacitance retention after 6000 charging/discharging cycles. Moreover, the developed all-solid-state micro-supercapacitor successfully powered a light-emitting diode, showcasing its significant potential for practical energy storage applications.

It is challenging to produce soft polymer materials with high surface area and nanoscale morphology that can be used for continuous flow water treatment in a processable, versatile, and stable manner. Here, we manufactured a processable Ag@CMPA-bph and used it to treat pollutants in wastewater at continuous flow conditions. The aerogel was prepared by a simple reduction method of CMP matrix and Ag metal precursors. Thermogravimetric analysis and electron microscopy showed that the aerogel had excellent thermal stability and distribution of fine Ag nanoparticles. The synthesized aerogel inherits the controllable properties of the CMP matrix and can be tailored to a specific shape for installation into the water treatment unit. In continuous flow conditions, this aerogel shows excellent catalytic activity to efficiently treat the combined pollutant containing p- nitrophenol and methyl orange ( p- NP&MO), which can reach a removal rate of more than 99 % at the flow rate of 0.6 L h -1 . Furthermore, the Ag@CMPA-bph can also be used for continuous flow treatment of pollutants in river water sample and shows robust anti-pollution load capacity and catalytic activity.

Deep eutectic solvent (DES) is a newly-emerged green solvent for efficient pretreatment of lignocellulosic feedstock. To improve the component fractionation performance of neutral DES , p- toluenesulfonic acid ( p- TsOH) was employed as catalyst to form a novel ternary DES with benzyltriethylammonium chloride (TEBAC) and glycerol (Gly) for pretreatment of soybean straw. Under the optimum reaction conditions (TEBAC:Gly = 1:12, 1.6 wt% p- TsOH and reacted at 90 °C for 160 min), the lignin and hemicellulose removal from soybean straw were amounted to 92.0 % and 88.2 %, respectively. The pretreated substrate showed satisfactory enzymatic hydrolysis performance, as the glucose and reducing sugar concentrations reached 37.3 g/L and 42.3 g/L, respectively, after 72 h saccharification under the action of cellulase with a relatively low enzyme loading of 10 FPU/g cellulose. This method provides an efficient and mild route for utilization of agricultural waste and production of platform monosaccharides.

Halide solid electrolytes (SEs) show great potential in all-solid-state batteries (ASSBs) because of their high ionic conductivity and high oxidative stability. But the long-term cycling stability remains a major concern due to the cathode/halide interface side reactions, especially under high current density. Herein, a s-p-d orbital hybridization strategy is proposed via introducing Zr 4+ and F − into Li 3 InCl 6 (LIC-ZrF 4 ) to regulate the electron localization structure around the central In 3+ . The electron transfer between the cation and Cl is alleviated by the enlarged bandgap (4.485–4.894 eV) with ZrF 4 introduction, and more electrons aggregate around In 3+ after s-p-d hybridization among Zr, In, and Cl. This effectively prevents LIC-ZrF 4 from being attacked by O atoms in LiNi 0 . 8 Co 0 . 1 Mn 0 . 1 (NCM811) and significantly suppresses the interface side reactions. The in situ formed LiF-containing layer further enhances the interface stability. The assembled ASSB (NCM811/LIC-ZrF 4 /LPSC/Li-In) exhibits a state-of-the-art capacity retention (96.7%@500cycles@1C; 80.7%@1600 cycles@2C). Furthermore, the ionic conductivity of LIC-ZrF 4 is also enhanced from 0.6 to 1.5 mS cm −1 while the electronic conductivity is decreased from 3.66 × 10 −8 to 8.39 × 10 −9 S cm −1 . This work highlights the crucial role of s-p-d hybridization on the electron localization regulation and the interface stability, and presents some distinct insights into developing high-performance halides-based ASSBs.

Single-atom catalysts with atomically dispersed M-Nx active sites have been widely used as nanozymes for colorimetric sensing due to their similar structure to natural enzymes , but they are still limited by their biological activity. Herein, controllable synthesis of B-doped Zn–N–C (ZnBNC) single-atom nanozymes (SAzymes) was designed and realized for the first time as a potent peroxidase mimetic. Based on the peroxidase-like activity of ZnBNC SAzymes, a novel colorimetric method was developed for the highly sensitive and selective detection of p-phenylenediamine (PPD) with a wide response range (0.3–10 μM) and a low detection limit (0.1 μM), which can be used as an alternative method for the detection of PPD in hair dyes and dyed hair samples.

In order to develop a biodegradable agent for food preservation, β-cyclodextrin (β-CD) inclusion complexes containing p -Anisaldehyde (PAA) were prepared using co-precipitation method. Physical properties including moisture content, bulk density, hygroscopicity, entrapment efficiency and loading capacity of the inclusion complexes showed considerable results for food applications. SEM and particle size test showed notably difference between the prepared inclusion complexes and the other formulations including the raw β-CD, physical mixture, and the recrystallized β-CD in both shape and size distribution. FTIR , XRD, TGA and DTA were also carried out and confirmed the formation of inclusion complexes and inhibition of the volatility of encapsulated PAA. As a potential preservation agent, inclusion complexes demonstrated a sustained released behavior in phosphate buffer saline (PBS). Comparing with pure PAA, the inclusion complexes presented a better storage stability in low humidity environment, a higher antioxidant activity , and equal MICs against Escherichia coli and Staphylococcus aureus .

Vitamin E derivatives possess many essential features for drug-delivery applications, such as biocompatibility, stability, improvement of water solubility of hydrophobic compounds, anticancer activity, and the ability to overcome multidrug resistance (MDR). Herein, vitamin E derivatives are used to overcome MDR through a combined P-glycoprotein (P-gp) inhibition and mitochondrial impairment strategy. A novel nanomicellar drug-delivery system as a carrier for doxorubicin (DOX) was developed, in which d-α-tocopheryl polyethylene glycol 1000 succinate was used as a P-gp inhibitor, α-tocopheryl succinate was introduced as a mitochondrial disrupting agent, and d-α-tocopheryl polyethylene glycol 2000 succinate was used as the main building block of micelles. The optimal ratio between the components of the nanocarrier was determined. The resultant DOX-loaded mixed micelles exhibited a suitable size of 52.08 nm, high drug-loading encapsulation efficiency (>98%), high stability, and pH-dependent drug release. In vitro experiments demonstrated a significantly increased cytotoxic activity of DOX-loaded mixed micelles against resistant MCF-7/Adr cells (45-fold higher than DOX after 48 h of treatment). In vivo studies revealed superior antitumor efficiency with less cardio- and hepatotoxicities of DOX-loaded micelles compared with that of free DOX. These results highlight that the developed DOX-loaded mixed micelles have a promising potential to overcome MDR in chemotherapy for clinical usage.

Nano-p–n junction heterostructures based on TiO2 nanobelts with enhanced (001) facets were produced by assembling p-type semiconductor NiO nanoparticles on n-type surface-coarsened TiO2 nanobelt surfaces. The heterostructures were then used as the sensing electrode for the electrochemical detection of anticancer drugs O6-benzylguanine (O6BG) and lung cancer cells. O6BG exhibited an irreversible diffusion-controlled electrochemical process with an oxidation peak clearly identified at +0.78 V. For lung cancer cells one oxidation peak was found at +1.1 V and two reduction peaks at +0.30, and +0.90 V. These voltammetric features disappeared when O6BG was added to the lung cancer cells, which was ascribed to the structural changes of the cell membranes caused by the anticancer drug. These results suggested that nano-p–n junction heterostructures based on TiO2 nanobelts might serve as promising candidates for biosensing applications of anticancer drugs and tumor cells that will be of significance in diagnostic medicine, cancer diagnosis and molecular biology research.

A novel fluorescent probe , fluorescent dialdehyde cellulose (FDAC), was prepared to detect p -phenylenediamine (PPD) in water samples conveniently and quickly. This was achieved by grafting 7-amino-4-methylcoumarin (AMC) onto dialdehyde cellulose (DAC) via an aldol–amine condensation reaction. This method is greener, more economical, and simpler than existing methods for preparing fluorescent probes. The probe was found to be more effective for PPD detection in polar solvents, with less interference from pH and other compounds present in the sample matrix. The photoluminescence of FDAC at λ ex /λ em = 340/430 nm was statically quenched by PPD, allowing for accurate detection within the range of 10–100 μmol/L under optimal conditions, with a detection limit of 3.2 μmol/L (3 σ/s). Meanwhile, the Schiff base (–C=N– group) generated by the condensation of DAC and AMC increased the reaction activity of the fluorescent moiety and changed the AMC conjugated structure, making FDAC more susceptible to aminolysis with PPD than AMC. This study presents a promising solution for fluorescence detection of aniline compounds, with significant potential for application in fields such as environmental analysis.

The BiOBr:Yb 3+ ,Er 3+ /g-C 3 N 4 (BYE/CN) p-n junction photocatalysts were successfully fabricated by a stepwise method. Experimental results show that Er 3+ /Yb 3+ were successfully doped into BiOBr lattice. As-obtained BYE/CN exhibited strong NIR light absorption and upconversion emission from NIR to UV–visible due to the upconversion transition of Er 3+ . The p-n junction was constructed due to the appropriate alignment band structure of BYE and g-C 3 N 4 , which distinctly suppresses the recombination rate of electron-hole pairs. Compared with pure BYE and CN, as-synthesized BYE/CN samples exhibit distinctly improved photoactivities under the irradiation of visible or NIR light, which can be attributed to the upconversion effect of Er 3+ and the construction of p-n junction. This result may provides a promising system for efficient harvest of the NIR light, which will contribute to the utilization of solar energy in the future.

In this paper, poly(N-isopropylacrylamide-co-3-aminophenylboronic acid) (P(NIPAM-co-APBA)) copolymer films were successfully electropolymerized on the Au electrode surface. The electroactive probe ferrocene carboxylic acid (FCA) in solution showed reversible thermal-, glucose- and pH-responsive on–off cyclic voltammetric (CV) behaviors at the film electrodes. The comparative experiments demonstrated that the thermo-responsive property of the film electrode was ascribed to the PNIPAM component of the films, whereas the glucose- and pH-sensitive behaviors came from the PAPBA constituent. The reduced form of nicotinamide adenine dinucleotide (NADH) could be electrocatalytically oxidized by FCA at the film electrodes, which would greatly amplify the multi-responsive CV signal difference between the on and off states. On the basis of these results, a binary 4-input/4-output logic circuit was fabricated with temperature, glucose, pH and NADH as inputs and the CV responses at 4 different levels as outputs. Moreover, a ternary CONSENSUS logic circuit was established on the same platform, which was the first report on the combination of ternary logic gate and bioelectrocatalysis without using enzymes. This work provided a novel idea for constructing complicated biocomputing systems by increasing the number of inputs/outputs with multi-sensitive interfaces and by designing new types of multi-valued logic gates on the basis of bioelectrocatalysis.

Ag 2 O nanoparticles-loaded Bi 5 O 7 I microspheres forming a three dimensional Ag 2 O/Bi 5 O 7 I p – n heterojunction photocatalyst with wide-spectrum response were synthesized in this study. The results of transmission electron microscopy observations revealed that the Ag 2 O nanoparticles with the diameter of ca. 10–20 nm were distributed on the surfaces of Bi 5 O 7 I nanosheets. The as-synthesized Ag 2 O/Bi 5 O 7 I exhibited an excellent wide-spectrum response to wavelengths ranging from ultraviolet (UV) to near-infrared (NIR), indicating its potential for effective utilization of solar energy. Compared with pure Bi 5 O 7 I, the Ag 2 O/Bi 5 O 7 I composite also demonstrated excellent photocatalytic activity for the degradation of Bisphenol A and phenol in aqueous solution under visible LED light irradiation. Among samples, the 20% Ag 2 O/Bi 5 O 7 I composite photocatalyst showed the highest photocatalytic activity for the degradation of Bisphenol A and phenol in aqueous solution. In addition, the 20% Ag 2 O/Bi 5 O 7 I composite also exhibited a photocatalytic activity for the degradation of Bisphenol A under NIR light irradiation. The improved photocatalytic activity is attributed to the formation of a p - n heterojunction between Ag 2 O and Bi 5 O 7 I, allowing the efficient utilization of solar energy (from UV to NIR) and high separation efficiency of photogenerated electron-hole pairs. The present work is desirable to explore a possible avenue for the full utilization of solar energy.
