Various grades of manganese dioxide ores, as a natural recyclable sorbent, can be used in dry flue gas desulfurization (FGD) at moderate temperatures (350–450 °C). This research provided low- and high-grade manganese dioxide ores to examine SO removal in a packed bed reactor. To obtain characteristic parameters of mineral sorbents, XRD, XRF, BET, and mercury porosimetry were employed. Then, kinetic parameters of desulfurization reaction were determined using thermogravimeter analyzer (TGA) and random pore model (RPM) for a single pellet. In desulfurization experiments of simulated flue gas in a packed bed reactor and mass spectrometer (MS) apparatus, the breakthrough times were measured under various operating conditions. The onset of these breakthrough times or life-time of MnO reactor for the SO removal was predicted successfully by RPM for a packed bed reactor using related kinetic constants from TGA. In addition, reacted sorbets were recycled multiple times after washing with water. Not only does this simple method separate MnSO from unreacted sorbents as a valuable byproduct to reduce the FGD cost, but it also improves pore size distribution (PSD) of mineral MnO by creating large pores. Modified PSD of this recycled sorbent caused increased breakthrough time.

Membrane fabrication via phase inversion depends on various influential parameters which may result in enhanced membrane performance. In this study, metal oxide nanoparticles i.e. FeO/ZnO were modified with glycine and diethylene glycol and then embedded onto polyethersulfone (PES) membranes to form PES/FeO/ZnO membranes. These membranes were used to remove manganese, copper, and lead ions from wastewater. Transmission electron microscope images confirmed that FeO/ZnO were composed of cubic and spherical morphologies. Fourier Transform Infrared spectra confirmed that FeO/ZnO nanoparticles were successfully modified using glycine and diethylene glycol. The surface and cross-sectional images showed that polyvinylpyrrolidone (PVP) and the coagulation bath temperature influenced the resulting membrane surface and confirmed the successful addition of nanocomposite concentrations (0.25, 0.50 and 0.75 wt%) onto PES membranes. The 0.50 wt% FeO/ZnO loaded membrane showed highest permeability with water flux of 682 L/m.h, and high flux recovery ratio (%) of 98.75 %, 88.88 % and 71.77 % for BSA, HA and wastewater samples, respectively, indicative of less prone to fouling. The chemical and mechanical enhancement through PVP concentration, coagulation bath temperature and nanoparticle loading significantly influenced the selectivity and fouling propensity of the PES membranes. Therefore, all parameters played a role in tuning the chemical and physical structure of the prepared membranes.

We developed a novel MXene/polymer hybrid material for enhanced photodegradation of multiple organic dyes. Specifically, uniform-sized PMMA microspheres and multilayer TiCT MXene were integrated through a facile solution process to form PMMA/TiCT composites. The hybridization of the two components significantly increased the specific surface area and pore volume. An optimized composite showed high photocatalytic activity, demonstrating 93 and 98 % degradation efficiencies for orange G (OG) and rhodamine B (RhB) in 60 min of light illumination. Furthermore, the composite revealed good recyclability without a significant performance drop even after four cycles. Moreover, the composite retained its high photocatalytic activity at various conditions, including elevated temperatures, a wide range of pH levels, and in tap water. These results manifest that the PMMA/TiCT hetero-photocatalyst is well suited for use in wastewater treatment and environmental cleanup.

Water pollution due to organic pollutants poses a significant environmental threat, necessitating the development of effective materials for their complete removal. This study introduces a novel Z-scheme ZnFeO/MWCNT/BiOBr (ZMB) ternary composite to enhance the removal of brilliant green (BG) dye and tetracycline hydrochloride (TCH) antibiotic. The synthesized materials were comprehensively analyzed using a range of characterization techniques, including XRD, UV–Vis DRS, FTIR, SEM, TEM, EDX mapping, BET, and XPS. A series of ternary composite materials with varying percent mass ratios of ZnFeO was synthesized, of which the optimized 6ZMB composite (6 % mass ratio of ZnFeO) demonstrates the highest degradation rates for BG (99.9 %) and TCH (95.1 %) within 20 and 100 min, respectively. Trapping experiments confirmed that O• and •OH were the main reactive species responsible for the degradation of BG and TCH pollutants. The NBT transformation experiments and PL terephthalic acid probe method further confirmed the involvement of O• and •OH, respectively. Furthermore, the adsorption isotherm study showed that BG adsorption onto the 6ZMB ternary composite predominantly followed the Langmuir model, with a high regression coefficient (0.9963 and 0.9777 for linear and nonlinear fit, respectively), indicating effective and consistent adsorption through chemisorption.

Here, a hybrid mesoporous sheets-like nano-catalyst was used to investigate the degradation of Congo Red (CR) dye. The photocatalytic efficiency of CR dye degradation was evaluated using a variety of mesoporous hybrid materials containing P,S,N-doped carbon (PC1), CoO@P,S,N-doped carbon (PC2), NiO@P,S,N-doped carbon (PC3), and NiCoO@P,S,N-doped carbon (PC4) sheet-like. The results indicated that the PC4 nano-catalyst exhibited exceptional efficacy in the photocatalytic degradation of CR dye, achieving a degradation efficiency exceeding 99 %. The results also showed that PC4 possessed a band gap of 1.7 eV. To formulate an effective photodegradation system, Analysis of Variance (ANOVA), a valuable statistical method, was employed to examine how varying pH, PC dose, and irradiation time can improve the photodegradation performance. Influential key parameters, including pH, PC dose, irradiation time, and CR concentration, were optimized through response surface methodology applying a four-factor, three-level Box-Behnken design (BBD). To achieve a 99 % decolorization of CR, the optimum conditions were determined to be pH 3.8, PC dose at 14 mg, irradiation time of 10.2 min, and CR concentration of 14.3 ppm. Kinetic models demonstrated that CR degradation followed pseudo-first-order kinetics. Moreover, band gap comparisons, scavenger analysis, and density functional theory (DFT) were used to discuss the CR degradation mechanism.

Supercapacitors are high-performance electrochemical energy storage devices with high power density, long cycle life, and rapid charge and discharge capabilities. However, in the conventional electrode fabrication process, the addition of binders without conductivity and electrochemical activity reduces the mass of active materials and increases resistance in the electrode, which compromises its electrochemical performance. Therefore, the binder-free electrode is an effective method to enhance the electrochemical performance and energy density of electrodes. The different fabrication technologies for binder-free electrodes have been explored in detail, especially focusing on surface growth on current collectors, self-assembly techniques, and the new technological methods. The design of electrochemically active materials, including carbon, metal compounds, and conductive polymers have been emphasized, along with the optimization of processes and the enhancement of performance, interface engineering and improvements in electrode functionality, the utilization of multifunctional performance materials, and the design and optimization strategies grounded in theoretical simulations. Depending on the actual situation, binder-free electrodes can increase energy density and specific capacitance 10% to 30% approximately. Finally, the advantages of binder-free electrode technology in supercapacitors and other energy storage fields are introduced, further exploring future research directions and the potential breakthroughs and challenges that binder-free electrode technology may bring.

A wireless-integrated tumor microenvironment-responsive sensor designed from diselenide-functionalized carbon dot (dsCD) and hyaluronic acid polymer dot (PD(HA)) loaded in a mineralized conductive hydrogel (dsCD-PD(HA) Hydrogel) for detecting cellular reactive oxygen species (ROS) and pH detection. The manufactured ROS/pH responsive conductive hydrogel efficiently differentiated between cancer cells and normal cells in response to cellular factors through changes in fluorescence, electrical and mechanical response. Tumor microenvironment acidity and high ROS concentrations caused fluorescence recovery boronate ester and diselenide bond cleavage alongside a change in electrical resistivity from 78.9 kΩ (pH 7.4) to 38.8 kΩ (0.1 mM HO/pH 6.8) due to disintegration of molecular interaction in the sensor. In vitro electrochemical analysis revealed different ΔR/R bending profiles between cancer (26.2 % and 25.9 % for HeLa and PC-3, respectively) and normal cells (17.9 %), alongside the optical performance demonstrating higher regain of fluorescence of cancer cells (HeLa and PC-3) compared to the normal cells (CHO-K1). Additionally, the dsCD-PD(HA) Hydrogel demonstrated favorable biocompatibility and ROS scavenging, with selective targeting of cancer cells. A wireless sensing platform was developed by connecting the dsCD-PD(HA) Hydrogel sensor to a smartphone, showing a precise signal during detection resistance or electro-mechanical signals.

A route was proposed to separate bismuth, iron, and rare earth elements from a solution containing nickel and magnesium through one-step extraction and two-step stripping. Firstly, saponified di-(2-ethylhexyl) phosphoric acid (D2EHPA) was used as the extractant to separate target elements. RE(III), Bi(III), and Fe(III) could be separated from Ni(II) and Mg(II), with extraction efficiencies of more than 99 %. Secondly, RE(III), Bi(III), and Fe(III) were stripped selectively by nitric acid and oxalic acid, respectively. Subsequently, the iron present in the oxalic acid stripping solution was treated under UV irradiation for 15 min to recover oxalic acid and obtain the ferrous oxalate product. The stripping efficiencies of RE(III), Bi(III), and Fe(III) were up to 100 % for four-stage countercurrent stripping, and the recovery rates of RE(III) and Bi(III) were 97.3 % and 99.2 %. The purities of nitrate rare earth enrichment solution, bismuth oxalate and ferrous oxalate were 99.7 %, 98.4 % and 99.5 %, respectively. In addition, the extraction dynamic demonstrated that the double salt precipitation was not observed during the extraction when the extraction time exceeded 7 min and the extraction mechanism was analyzed using the slope method. This process shortens steps, and is more efficient to separate RE(III), Bi(III), and Fe(III) from the mixed solution containing Ni(II) and Mg(II), which has a prospective industrial application.

This study focuses on newly synthesized compounds derived from hydrazine derivatives, specifically methyl carbazate (MCZ, CHNO) and 2-thiobarbituric acid (2-TBA, CHNOS). The reaction between MCZ and 2-TBA resulted in the formation of three types of salts with the following compositions: [(CHNO)(CHNOS) (CHNO)(CHNOS)(CHNO) ), and (CHNO)(CHN)(CHNOS) [(CHN) represents the triethyl ammonium cation]. The prepared salts were comprehensively characterized, showing that compound exhibited a monoclinic crystal structure and met Lipinski’s rules, indicating significant drug-like properties. Molecular docking analysis revealed that these compounds exhibited strong binding affinities toward bacterial proteins, particularly and , indicating their potential as antibacterial agents.

Liquid phase exfoliation (LPE) of graphite is a promising pathway for graphene flakes (GF) due to its scalability and cost-effectiveness. However, the method has significant limits at the industrial scale, such as low yield of GF and long processing times. In this study, we investigate the effect of organic solvents such as N-methyl-2-pyrrolidone (NMP) and methyl-5-(dimethylamino)-2-methyl-5-oxopentanoate (PolarClean) temperature on shear-induced exfoliation. The GF concentration was successfully obtained 0.62 mg/ml in NMP and 0.68 mg/ml in PolarClean within just 2 h at 263 K, without surfactants or any additional additives. These results revealed the improved exfoliation efficiency due to changes in solvent polarity, surface tension, and dispersion stability with increased viscosity. In addition, we investigate the optimization conditions required for liter-scale shear-induced exfoliation of graphite in PolarClean. As-prepared GF has significant potential as an effective nanofiller for enhancing the mechanical strength of commercial polymers. This study not only advances the understanding of the LPE mechanisms but also paves the way for the industrial application of this method in the green synthesis of graphene-based nanocomposites.
