The increasing energy demands stemming from the extensive utilization of portable electronic devices are creating a huge energy deficit between demand and supply. In this scenario, it is not only sufficient to pursue and innovate the new renewable energy sources but also requires an ideal device for energy storage and conversion.
Methods
In this work, activated carbon (AC) was prepared from matured bark of Acacia catechu through a series of steps; pre-carbonization, carbonization, and activation. The AC was synthesized at different temperatures (400–800 °C) under inert atmosphere, using orthophosphoric acid as an activator. As-prepared sample (ACBH) was characterized by well-known characterization techniques. Energy storage capability was assessed in terms of Cyclic voltammetry, Galvanostatic charge-discharge, Electrochemical impedance, and Cyclic stability by three-electrode setup.
Significant findings
The ACBH-8 sample demonstrated superior electrochemical performance compared to other samples. The sample ACBH-8, as Negatrode, exhibited a specific capacitance of 282.4 F g−1 at 0.5 A g−1 and retained 95.4 % cyclic stability under 10,000 cycles. The excellent energy storage performance by green-class negatrode materials from the bio-waste substance empowers commercial applications.

Background
Carbon dots (CDs) are zero-dimensional fluorescent materials that attract attention due to their unique optical properties and size. This study utilizes Coccinia grandis (ivy gourd) for synthesizing CDs, focusing on detecting Fe3+ ions due to environmental and health concerns linked to iron levels. Iron imbalances can cause health issues like anemia and Alzheimer's disease, emphasizing the need for monitoring iron levels in water.
Methods
Coccinia grandis was utilized to synthesize CDs via one-step hydrothermal carbonization. Coccinia grandis fruits were carbonized through a hydrothermal process, resulting in the production of CG-CDs that were subsequently isolated and dehydrated to obtain a powdered form suitable for further analysis and application.
Significant findings
Characterization revealed CG-CDs with small (∼4 nm) and uniformly distributed particles, moderately graphitized. CG-CDs exhibited strong fluorescence without passivation agents, achieving a quantum yield of 17.5 % at 350 nm excitation. The CG-CDs were effective in sensing Fe3+ ions (limit of detection = 0.53 μM) in water, validated by a Stern-Volmer plot (R2 = 0.997). This work demonstrates the potential of eco-friendly biomass like Coccinia grandis for producing efficient fluorescent sensors, aiding in Fe3+ ions detection for environmental and health applications.

Background
Novel organoselenium (OSe) corrosion inhibitors, namely 2-(((4-(benzylselanyl)phenyl)imino)methyl)-5-nitrophenol (BSeOH) and its Ni (II) chelate [Ni(BSeO)2(H2O)2] were synthesized in 90 % and 88 % yields, respectively. Their chemical structures were characterized using different spectroscopic tools.
Methods
The corrosion inhibition efficiency was investigated toward C1018-steel in 1.0 M HCl solutions using potentiodynamic polarization, impedance spectroscopy, X-ray photoelectron spectroscopy, density functional theory, and Monte Carlo simulations. Several quantum chemical parameters were calculated using Density Functional Theory at the B3LYP/6–31G* computational model to elucidate the inhibitory activity of the compounds.
Significant findings
Electrochemical data showed that [Ni(BSeO)2(H2O)2] has more protection efficiency (96.4 %) compared to its ligand BSeOH (93.4 %) at 15.0 × 10−6 M. In addition, the corrosion current density (icor) decreases (245.96 to 8.96 µAcm−2), the charge transfer resistance (Rct) increases (95.15 to 1926.70 Ω cm2), and the admittance (Y0) decreases (173.87 to 18.07 μΩ−1 sn cm−2) with the inhibitors’ dosage indication the formation of a protective adsorbed layer on the steel surface. Furthermore, the BSeOH and [Ni(BSeO)2(H2O)2] inhibitors were spontaneously adsorbed on the steel surface, adhering to the Langmuir isotherm. Moreover, the electrochemical and theoretical results showed that these inhibitors were effectively adsorbed on the C1018-steel surface as a preventive layer. Collectively, the utilization of OSe agents as corrosion inhibitors is a novel approach that combines several advantageous characteristics, including improved efficiency, unique chemical properties, multiple inhibition mechanisms, and the potential for derivatization. Therefore, OSe inhibitors hold significant promise in the field of corrosion prevention and further studies are highly required to develop a more substantial strategy to fight corrosion by applying OSe compounds.

Background
Silver nanoparticles (AgNPs) are renowned for their broad-spectrum antibacterial properties. Various synthesis methods, particularly green synthesis using biogenic agents, have garnered significant attention. However, the detailed impact of green-synthesized AgNPs on the antibacterial mechanism against Staphylococcus aureus remain unclear, limiting the full potential of green synthesis compared to chemical methods.
Methods
AgNPs were synthesized via chemical (sodium citrate, NaBH4) and green synthesis (green tea leaves, cassia seed extract) methods. The synthesized AgNPs were evaluated for toxicity and antibacterial activity against Staphylococcus aureus.
Significant findings
This study revealed a strong correlation (R2>0.9) between minimal inhibitory concentration (MIC) and AgNP size for both synthesis methods, with a similar exponential trend. MIC values were 45, 40, 25, and 5 µg mL-1 for citrate-, NaBH4-, green tea extract-, and cassia seed extract-assisted synthesis, respectively. Green-synthesized AgNPs showed higher antibacterial activity than chemical AgNPs at comparable sizes. Chemical AgNPs exhibited low and fluctuating scavenging activity, while green methods were more consistent. Cytotoxicity was noted in chemical AgNPs and at high concentrations of green tea extract-assisted AgNPs. Bacterial membrane disruption and ROS accumulation were also observed, contributing to the enhanced antibacterial activity of green-synthesized AgNPs.

Antibiotic identification with precision is crucial. Vanadium selenide (V3Se4) was synthesized and later encapsulated onto the beta-cyclodextrin/reduced graphene oxide nanosheets (β-CDN/rGONs) to achieve efficient electrochemical sensing of moxifloxacin hydrochloride (MFH) in water and biological samples. Due to their unique characteristics as composite structures, transition metal chalcogenides (TMDs) with carbon composite (V3Se4/ β-CDN/rGONs) were produced.
Methods

Transmission electron microscopy were done to study the morphological properties of the material. The morphological analysis revealed spherical structure of the (V3Se4) material and wrinkled sheets of β-CDN/rGONs.

Background
The synthesis of Metal-Organic Frameworks (MOFs) is increasingly focused on achieving green and cost-efficient methods while producing high-quality products with abundant active sites. This approach is attracting significant attention from researchers. One promising method, modulated synthesis, stands out for its ability to induce structural defects in MOFs and enhance their active sites. However, the challenges in identifying the optimal conditions for critical factors, particularly the quantitative correlation between the modulator and crucial independent variables influencing MOFs performance, underscore the importance of research work in this field.
Methods
This study synthesized tin-based MOFs (Sn-MOFs) utilizing a linker derived from recycled polyethylene terephthalate (PET) waste. A hydrothermal approach was employed, utilizing water-like solvents and trifluoroacetic acid (TFA) as a modulator to effectively induce structural defects. Response Surface Methodology (RSM) was applied to evaluate the effects and interactions of temperature, reaction time, and TFA concentration on optimizing yield and crystalline index (CI) while simultaneously reducing the residual percentage of 1,4-benzene dicarboxylate (H2BDC) in the Sn-MOFs (DI).
Significant findings
The research revealed that temperature, reaction time, and TFA concentration significantly influenced the performance of Sn-MOFs, highlighting the considerable potential of TFA in creating active sites and enhancing the surface area and pore volume of Sn-MOFs through defect engineering. Optimal synthesis conditions for Sn-MOFs included a temperature of 148℃, a reaction time of 24 h, and a molar ratio of H2BDC/TFA of 1.7, yielding 98.51 ± 1.47 % for yield and 80.21 ± 1.32 % for CI, with no detectable residual H2BDC.

Background
Bioelectrochemical systems (BES) are specialized systems that can convert chemical energy into electrical energy using bacteria as catalysts. Electrodes play an important role in electrical energy transfer through electrochemical reactions. Electrodes are selected based on their physiochemical properties to enhance biological reactions. In microbial fuel cells (MFC), the anode is crucial because electrogens adhere to its surface and produce electrons and protons. These electrons and protons are absorbed by the cathode surface to generate bioelectricity. Numerous substances, like carbon based, metal based, conductive polymers and gas diffused materials, can be used as anodes and cathodes.
Method
To improve their physiochemical properties, conductive polymers such as polypyrrole (PPy) and polyaniline (PANI) are combined with other substances. In MFCs', both anode and cathode are important components. In anodic location, oxidation occurs, which produces electrons and protons. A reduction reaction produces molecules of water at the cathode location. Various materials can be utilised to create cathodes and anodes. Materials such as carbon based, CC, graphite and metals can be utilized to create anodes. Materials based on carbon, such as CC, carbon black, and so on, as well as materials based on metal and gas diffusion can be employed to create cathode. The electrode's surface material layer is created using electrode manufacturing techniques. Screen printing, electrochemical deposition, and chemical vapor deposition are the most of commonly used methods. Applications for BESs are numerous and include bioremediation, biosensors, MFCs, and microbial electrolysis cells (MECs). Various waste products are used in anodic chambers of MFCs to create electrical energy. Methane, green hydrogen, formic acid, hydrogen peroxide, and other value-added compounds are produced by MECs, a modified form of MFCs. Toxic contaminants in BESs can be removed and transformed into products with increased value using bioremediation. Biosensors are essential tools for physiochemical parameter monitoring in real time in the current world. MFC is regarded as a biosensor for contrasting the energy generated with many other factors.
Significant Findings
This paper mainly focuses on the different materials of electrodes that are being used and fabrication techniques that enhance the productivity of electrodes in BES to reduce the organic waste load and generate bioelectricity.
