Metal-organic frameworks (MOFs) are gaining much attention in the field of energy storage due to their porosity and hybrid properties of inorganic–organic constituents. We report a synthesis of CuCo-MOF (CCM) using benzene-1,4-dicarboxylic acid as an organic linker via a less expensive reflux condensation method, which provides abundant active redox metal centers and accessible carbonyl-based redox sites for energy storage. Furthermore, XRD, FT-IR, Raman, SEM, and XPS are used to examine the crystalline structure and size, functional groups, morphology, and chemical states present in the CCM material respectively. The SEM micrograph shows sponge-like morphology which offers ion encapsulation ability helpful for fast electrolyte ion adsorption and desorption on the electrode surface. From BET analysis the surface area obtained was 192.027 m2/g for CCM material. Additionally, the CCM electrode exhibits excellent pseudocapacitive characteristics with a specific capacitance of 102.4F/g with remarkable energy and power density of 11.37 Wh kg−1 and 285.71 W kg−1 in the potential window range of −0.4 to 0.4 V at 3 mA cm−2 in a 2 M KOH electrolyte. To check the practical applicability, an asymmetric solid-state device was constructed which delivered an excellent specific capacitance of 111F/g with a maximum energy density of 22.2 Wh kg−1 and a power density of 1800 W kg−1. Therefore, the prepared CCM material plays a crucial role in the energy storage phenomenon.

Carbon dots (CDs), synthesized from Citrus hystrix peels, exhibited maximum fluorescence emission at 420 nm when excited at 330 nm. Along with Quercetin (QT), the CDs quenched the emission at 420 nm upon the addition of aluminium (Al3+) ions and the combination also yielded a new strong emission peak at 480 nm. The intensity of the emission peak at 480 nm increased with the increase in Al3+ concentration which is accompanied by a visible colour change of the solution from colourless to yellow. The formation of QT-Al3+ complex in the system results in the Inner Filter Effect (IFE) causing the change of blue fluorescence emission to green. Herein, a ratiometric fluorescent sensor has been constructed using CD-QT system which exhibits a great potential towards selective determination of Al3+ by overcoming the limitations possessed by single wavelength detection probes. The proposed sensor detects Al3+ over a wide range of 5–550 µM with the lowest detection limit of 0.695 µM. Also, this sensor hardly shows any vulnerability towards the most possible interfering Zinc ions and other potential metal ions. The proposed method has been successfully applied for the determination of Al3+ leached from aluminium food wrapper and cooking utensil with high selectivity. Excessive leaching of Al3+ into food has been evidenced while cooking in acidic conditions using this sensor. The fabricated fluorescent sensor has been used to detect Al3+ in sediments collected from large scale wheat storage warehouses, where aluminium phosphide is used as fumigant for pest control.

The utilization of ultrasound (US) technology for cancer diagnosis and treatment has garnered increasing interest in recent years. One area of particular focus is the integration of ultrasound and nanobubbles (NBs) in targeted cancer therapy. Nanobubbles are tiny bubbles with nanoscale dimensions that exhibit unique physical and chemical characteristics in their core and shell. These bubbles are designed to enhance the stability, bioavailability, and distribution of drugs when targeted to specific regions. The small size of nanobubbles allows them to easily exit the bloodstream and reach adjacent tissues, enabling precise and minimally invasive drug delivery using ultrasonography. Ongoing research aims to develop nanobubbles as contrast agents for bioimaging and targeted delivery. Fabricating nanobubbles typically involves ultrasonication, followed by techniques such as thin film evaporation, high shear emulsification, mechanical stirring, coacervation, or coalescence methods. When exposed to ultrasound or extracorporeal shock waves, the medicine contained within the nanobubbles is released into the target cells. This review article provides a concise overview of the formulation development processes and the various shell and core contents used in nanobubble development. It focuses on analyzing nanobubble systems that respond to ultrasound for cancer treatment, particularly in drug delivery and imaging applications. The research also explores ultrasound settings, nanobubble manufacturing, and the factors and challenges that affect their effectiveness. By offering comprehensive insights, this review serves as a valuable resource for scholarly investigations into the use of nanobubbles in cancer treatment. It delves into the potential benefits and challenges associated with their development and application. The persistent efforts in research and development within this domain will play a pivotal role in propelling the field of cancer therapeutics forward.

In the present report, In2S3/Ag2S heterojunctions were created hydrothermally and characterized for their crystalline structure, morphology, composition, optical characteristics, charges reunification and property of charge by standard analytical techniques. Synthesized nanomaterials were utilized for the decontamination of organic pollutants such as Rhodamine B (RhB) dye and antibiotic ciprofloxacin (CP) by using visible light radiance. Calculated photocatalytic removal efficacy for RhB and CP over In2S3/Ag2S nanocomposite was 99.95 % in 40 min and 99.49 % in 140 min respectively which is 1.98 and 1.21 times greater than In2S3 alone. Maximum removal efficiency was achieved for In2S3/Ag2S (3 wt%) composition. The enhanced activity is attributed to the greater absorption of visible light and construction of S-type heterojunction which are more efficient for light induced charge separation and therefore decrease the reunification of hole-electron carriers. Density functional theory (DFT) analysis also supported that the nanocomposite is energetically favorable, stable and show significantly electronic and photocatalytic properties. In2S3/Ag2S (3 wt%) nanocomposite achieved excellent photocatalytic stability towards the removal of RhB and CP even after five runs. In2S3/Ag2S (3 wt%) nanocomposites showed maximum photocatalytic activity in acidic medium. Effect of trapping agents towards removal of CP and RhB were conducted and results showed that.O2 radical play dominant role as active species in comparison to ⋅OH radical and holes. Plausible mechanism of transfer of charge in In2S3/Ag2S and removal of pollutants is also represented. Owing to their unique features, novel In2S3/Ag2S heterojunctions exhibits as an exceptionally effective photocatalyst for removal of pollutants and it would display the promising utilization towards wastewater treatment.

Stannic oxide, also known as tin (IV) oxide (SnO2), is commonly synthesized from a chemical derivative of a tin compound as an important inorganic compound as an anode material in lithium-ion batteries (LiB). This study developed a two-step synthesis technique, comprising alkaline degradation and thermal oxidation, to produce SnO2 from pure tin metal as the precursor. The results indicate a morphological change from Sn metal to SnO2 was observed, highlighted by a cavity structure at 500 °C to an interconnected network of individual SnO2 particles at 900 °C. These changes concurrently indicate the phase composition change of sodium-based compounds into pure cassiterite SnO2 at 900 °C. In this current research, the electrochemical properties of SnO2, with a purity level of 98.6 % and a yield ranging from 90 to 92 wt%, were also investigated. The electrochemical performance of cassiterite SnO2 deteriorated, evidenced by capacity loss, a negative trend in specific capacity, and irregular reduction and oxidation regions due to cyclic treatment. The initial discharge capacity of 770 mAh g−1 at 0.1C gradually decreases with a capacity loss of 29.9 % and maintains a cycle retention rate of 45 % after 100 cycles. The particle size expansion, high oxygen concentration, and reduced tin content after cyclic treatment are critical contributors to the degradation of electrochemical properties. The relationship among morphological structure, phase composition, and electrochemical properties is extensively investigated.

Production of clean hydrogen fuel (H2) has gained a significant importance nowadays through hydrogen evolution reaction (HER). However, a crucial requirement of HER is a low cost but an efficient catalyst. Single-atom catalysis has emerged as a promising strategy to meet this demand. In this study, we investigated late first row transition metals adsorbed six-membered boron rings (TM-B6; TM = Co, Cu, Zn, Ni, Fe) as potential single-atom catalysts for HER, aiming to identify less expensive electrocatalysts with high efficiency. Our findings demonstrate that complex reactions are thermodynamically favorable, highlighting their synthetic applicability. All transition metal doped B6 complexes have adsorption energies of −1.08 to −3.54 eV. Natural bond orbital (NBO) analysis indicated the charge transfer from transition metals to the boron ring, and then to hydrogen upon adsorption. HOMO-LUMO energy gaps of transition metal-adsorbed boron complexes range from 3.15 to 5.19 eV, and changed after hydrogen adsorption, confirming electronic stability. Molecular dynamic (MD) analysis elucidated the high stability of the pure and doped complexes at very high temperature. Noncovalent interactions and density of states analyses further confirm the potential of transition metal-adsorbed boron complexes as a supportive surface for HER.

However, studies generally focus on absolute values of adsorption (or other) properties. Pretreatment of carbonaceous materials, whether at high or low temperatures, plays a key role in generating the precursor structure that is subsequently activated. Our research addresses a gap in the existing literature by exploring how pretreatment conditions influence the properties of activated carbon. For the first time, we show how both the pretreatment atmosphere (inert or air) and the temperature used affect the final structure and adsorption performance of polyacrylonitrile-based activated carbons. We found that as the pretreatment temperature increases, the specific surface area decreases, and the crystallite size grows. The sample without any pretreatment showed the largest surface area of 2298.3 m2/g and the best adsorption capacity for methylene blue, reaching 508.4 mg/g. However, it also possesses the lowest nitrogen content, affecting its suitability for certain applications. Additionally, pretreatment atmosphere influences surface characteristics, with inert pretreatment resulting in higher hydroxyl group concentration compared to air pretreatment. This difference in hydroxyl groups contributed to varied adsorption values, measuring 441.2 and 422.6 mg/g for the inert and air pretreated samples, respectively. This highlights the importance of both pretreatment temperature and atmosphere in tailoring the properties of activated carbons for diverse applications.

Unlike traditional semiconductors, chalcogenide perovskites offer a unique combination, merging the stability and safety of oxides with the tunability of halide semiconductors, making them particularly promising for photocatalytic and photovoltaic applications. This paper theoretically investigates the optoelectronic properties of the triclinic ABS3 (A = Li, Na, K, Rb, Cs; B = Si, Ge, Sn) perovskites using density functional theory with the HSE06 hybrid functional. The feasibility of synthesizing ABS3 materials was revealed using formation energy calculations. Band structure and density of state calculations confirm that all compounds under investigation are semiconductors exhibiting indirect bandgaps. These bandgaps increase with the ionic radius of the A-site cation, following the trend Li < Na < K < Rb < Cs. Additionally, the order of bandgap energies for the B-site elements is observed as Si > Sn > Ge. This trend emphasizes the significant influence of cation size on the electronic properties of perovskite materials. The investigated perovskites exhibit bandgaps between 1.67 and 3.55 eV, with a narrow difference (0.03–0.49 eV) between their indirect and direct gaps. We additionally compute various optical parameters (dielectric function, refractive index, extinction coefficient, optical conductivity, absorption coefficient, reflectivity, and energy loss function) across the 0–50 eV energy range. The valence and conduction band edge potentials of ABS3 perovskites were calculated to evaluate their potential applications in water splitting, carbon dioxide reduction, and photodegradation processes. The results of this study demonstrate that several ABS3 semiconductors exhibit promising characteristics that position them as efficient photocatalysts for these photocatalytic reactions. LiGeS3 and NaGeS3, in particular, are promising for solar cell applications.

This study focuses on the synthesis and comprehensive characterization of ternary NiFe2O4/MnFe2O4/CeO2 nanocomposites. A suite of analytical techniques, including X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), Fourier-transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET) surface area analysis, and magnetic property measurements, were employed to investigate the structural, morphological, compositional, surface, and magnetic properties of these materials. A systematic approach was implemented for the synthesis of the nanocomposites. FE-SEM analysis revealed the morphology and size distribution of the nanoparticles, while XRD confirmed the formation of the cubic phase within the nanocomposites. An increase in calcination temperature (from 600 to 800 °C) resulted in an increase in average particle size (11, 12 and 22 nm). FTIR and XPS techniques were utilized to study the chemical bonding and surface composition, respectively. BET analysis demonstrated a substantial surface area, however, the surface area decreased with increasing calcination temperature (37.17, 13.7, and 4.16 m2/g). Magnetic property measurements revealed an enhancement in magnetic behavior (2.88, 6.65, and 10. 54 emu/g) with increasing calcination temperature, indicating potential applications in biomedical and magnetic storage fields. All in all, this work highlights the potential of NiFe2O4/MnFe2O4/CeO2 ternary nanocomposites for a variety of technological applications by illuminating their complex characterization.
