Summary: CMC@Fe3O4 composite, a magnetic biological molecule, was synthesized and used as an adsorbent to remove cationic dyes from aqueous solutions. Various techniques were used to characterize the adsorbent, including FTIR, FESEM, XRD, VSM, and TGA. The adsorption process was influenced by factors such as pH, temperature, contact time, adsorbent concentration, and initial dye dosage. The synthesized adsorbent showed spherical shapes and different sizes. The adsorption capacity of the dyes was determined, and the adsorption processes were found to be exothermic reactions. The regeneration and reusability of the adsorbent were also evaluated.

Summary: A new nanocomposite, A-CNF/DT, was successfully synthesized and used for the removal of methylene blue and indigo carmine dyes from water. Langmuir and Sips isotherm models well fitted the adsorption isotherm data of methylene blue and indigo carmine onto A-CNT/DT, respectively. The experimental kinetic data showed good agreement with pseudo-first order model (for the adsorption of methylene blue) and pseudo-second order model (for the adsorption of indigo carmine) onto A-CNT/DT. Thermodynamic parameters indicated that the adsorption of methylene blue was endothermic, while the adsorption of indigo carmine was exothermic. Monte-Carlo calculation method revealed both polar and nonpolar interactions between the dye molecules and the A-CNT/DT surface. Overall, the synthesized A-CNT/DT proved to be an efficient adsorbent for the removal of dyes from aqueous solutions.

Summary: This study investigates the evolution of dye adsorption properties of nitrogen-doped biochars synthesized from soy flour biomass at different pyrolysis temperatures. Higher pyrolysis temperature leads to increased amorphous graphitic carbon and mineral ash content. Treating the biochars with HNO3 improves the efficiency of adsorption by increasing the surface area and enhancing the surface oxidation.

Summary: Chitosan (CS)/carboxymethyl cellulose (CMC) porous hydrogels crosslinked by epichlorohydrin and with polyethylene glycol (PEG) as a pore-forming agent were synthesized for removal of anionic (Congo red, CR) and cationic (methylene blue, MB) dyes from aqueous solutions. The addition of PEG significantly increased the adsorption of CR and MB, with optimal performance observed for hydrogels prepared with 2% CS and 2% CMC (CS2/CMC2). The adsorption processes followed pseudosecond-order and pseudo-first-order kinetics models for CR and MB, respectively. Freundlich and Langmuir models were suitable for describing the adsorption isotherms of CR and MB, respectively. The thermodynamic study confirmed that the adsorption of CR and MB by the hydrogels was spontaneous, with CR adsorption being endothermic and MB adsorption being exothermic.

Summary: Dyes are widely used in various industries, but the wastewater they produce poses a threat to the environment due to its toxic effects. Common methods for removing dyes from wastewater, such as flotation and filtration, often result in the production of large amounts of sludge. Activated carbon adsorption is an effective method that can remove dyes without generating significant waste.

Summary: The study investigates the removal of cationic dyes from water using a novel material formed by strong polyanion, polystyrene sulfonate (PSS), on laterite soil. The modified soil, called polymer modified laterite (PML), showed high efficiency in removing crystal violet (CV) and methylene blue (MB), achieving removal rates over 92% and 83% respectively under optimal conditions. The adsorption isotherms and thermodynamic study indicated an exothermic process with Langmuir model conformity and confirmed electrostatic interactions as the key mechanism.

Summary: Heteroatom-doped carbon nitride (C3N4) materials were investigated as supports for Au nanoparticles, which were anchored on sulfur-doped carbon nitride nanosheets (AuNPs@SCNN) and used as a catalyst for arsenic electroreduction. The synthesis of novel SCNN was achieved through a simple thermally induced copolymerization route using ammonium persulfate (APS) as a sulfur source. The integration of SCNN with AuNPs improved the assembly quality and interface, leading to enhanced catalytic activity. The composite (AuNPs@SCNN/GCE) modified glassy carbon electrode exhibited enhanced electrochemical responses for the electrocatalytic reduction of arsenic.

Summary: The mechanism of the inner filter effect (IFE) can be effectively utilized in the design of innovative IFE-based sensors using resonance Rayleigh scattering (RRS) technique. Silver nanocubes (Ag NCs) with tunable extinction spectra were employed as RRS probes, and three typical analytes, doxorubicin (DOX), sunitinib (SUN), and Alizarin Red S (ARS), were considered. The results demonstrated the feasibility of the newly developed IFE mechanism as an attractive analytical technique for measuring different analytes.

Summary: We reported a novel electrochemical sensor for the indirect determination of cyanuric acid (CA) using the complex formation between CA and melamine (MEL) for the first time. The sensor utilized the electrochemical conversion of MEL to electroactive polymelamine, with the decline in current intensity upon the addition of CA serving as the sensor response. A calibration curve was constructed using square wave voltammetry, with a limit of detection of 80.28 mu mol L-1. The proposed method showed excellent recovery range (91.2-101.0%) for real sample analysis.

Summary: We report on the synthesis and characterization of a dual stimuli-responsive hydrogel for pH and temperature-sensitive delivery of curcumin (CUR) anticancer drug. The release of CUR from the hydrogel was higher at acidic pH values, and the hydrogel remained stable at 37 degrees C. To enable thermal responsivity, polydopamine nanoparticles were embedded in the hydrogel. The GGPDNCs hydrogel is engineered to respond to both pH and temperature stimuli.

Summary: In this research, the complexation of a newly synthesized covalent organic framework (schiff base network1) with different cations, including Hg2+, was studied. The results showed that schiff base network1 had a stronger interaction with Hg2+ compared to other cations, making it a potential ionophore for the development of a Hg2+ potentiometric sensor. A Hg2+ selective PVC membrane coated graphite electrode was successfully created using schiff base network1, which exhibited excellent response and sensitivity for the detection of Hg2+ in a wide range of concentrations. The electrode also demonstrated good performance in non-aqueous environments and had a long lifespan.

Summary: Rhabdomyosarcoma is a rare cancer that affects skeletal muscle, primarily in children and young adults. The treatment strategies for this disease include multi-agent chemotherapies following surgical resection and radiotherapy. This review provides a detailed clinical understanding of rhabdomyosarcoma, including its classification, diagnosis, and treatment strategies. The impact of apoptosis, macro-autophagy, and the unfolded protein response on chemotherapy response is discussed. Additionally, the use of in vivo mouse and zebrafish models and in vitro three-dimensional bioengineering models for screening future therapeutic approaches and promoting muscle regeneration is explored.

Summary: This paper describes the development of a low-cost yet efficient PEDD-based photometer. It utilizes a white LED as the emitter diode, an RGB LED as the detector diode (a novelty), and a multimeter for signal recording. The photometer was used to detect 2,4,6-trinitrotoluene (TNT) in soil samples by using a Meisenheimer complex of TNT with NaOH in acetonitrile as a probe. The method showed a linear calibration curve in the concentration range of 0.86 to 110 μg g(-1), with a detection limit of 0.27 μg g(-1) and a quantification limit of 0.81 μg g(-1). Analysis of soil samples from Iran Cinema and Television Town revealed trace residues of TNT.
