An updated overview of some factors that influence the biological effects of nanoparticles Nanoparticles (NPs) can be extremely effective in the early diagnosis and treatment of cancer due to their properties. The nanotechnology industry is developing rapidly. The number of multifunctional NPs has increased in the market and hundreds of NPs are in various stages of preclinical and clinical development. Thus, the mechanism underlying the effects of NPs on biological systems has received much attention. After NPs enter the body, they interact with plasma proteins, tumour cell receptors, and small biological molecules. This interaction is closely related to the size, shape, chemical composition and surface modification properties of NPs. In this review, the effects of the size, shape, chemical composition and surface modification of NPs on the biological effects of NPs were summarised, including the mechanism through which NPs enter cells, the resulting oxidative stress response, and the interaction with proteins. This review of the biological effects of NPs can not only provide theoretical support for the preparation of safer and more efficient NPs but also lay the foundation for their clinical application.

Mechanochemistry-Induced Strong Metal–Support Interactions Construction toward Enhanced Hydrogenation The construction of strong metal–support interactions (SMSIs) represented an attractive approach to producing supported noble metal nanocatalysts possessing enhanced stability by overlayer encapsulation. The development of facile approaches capable of achieving efficient, controllable, and extensive SMSI overlayer formation, particularly under neat and ambient conditions, is a long-standing challenge. In this work, a mechanochemistry-driven pathway was deployed for efficient and controllable SMSI construction under neat and ambient conditions to customize the capsulation degree and overlayer structures toward enhanced catalysis. The reducibility of the additives and the high interaction efficiency provided by the mechanochemical treatment could afford abundant active intermediates (e.g., Ti3+ species and oxygen defects) within a short time to induce and tune the overlayer encapsulation. This facile approach could be extensively deployed to TiO2-derived nanocatalysts with diverse phases, diverse reducible metal oxides-involved systems, and different supported noble metal nanoparticles. Enhanced hydrogenation activity was achieved by the as-afforded nanocatalysts upon SMSI construction and further tuned by the encapsulation degree.

A state-of-the-art review of N self-doped biochar development in supercapacitor applications Due to its renewability, eco-friendliness, and cost-effectiveness, biochar is a promising alternative to fossil fuel-based carbon for electrode material application in supercapacitors. However, pristine biochar often exhibits poor structure and low activity, which strongly inhibit its commercial utilization. N-doping is an efficient way to improve the electrochemical performance of biochar by enhancing the conductivity and surface wettability that further induce a pseudo-capacitance effect. Compared with external doping, the synthesis of N self-doped biochar from natural N-rich biomass without using external N precursors, which are harmful and costly, has attracted increasing attention. Few reviews of N-doped biochar applications in supercapacitors are available, and studies of N self-doped biochar are still scarce. This paper reviews the developments over the past 10 years on the preparation, activation, and application of N self-doped biochar in supercapacitors. Notably, the evolution of N-functionalities during N self-doped biochar production with or without activating agents was analyzed. The relationships between N content and the specific capacitance and the contribution of N self-doping-induced pseudo-capacitance to the total specific capacitance are also discussed. Finally, the challenges and the prospects of N self-doped biochar applications in supercapacitors are proposed.

Design and Application of Materials for Sequestration and Immobilization of <sup>99</sup>Tc <sup>99</sup>Technetium (<sup>99</sup>Tc) is a hazardous radionuclide that poses a serious environmental threat. The wide variation and complex chemistries of liquid nuclear waste streams containing <sup>99</sup>Tc often create unique, site specific challenges when sequestering and immobilizing the waste in a matrix suitable for long-term storage and disposal. Therefore, an effective management plan for <sup>99</sup>Tc containing liquid radioactive wastes (such as storage (tanks) and decommissioned wastes) will likely require a variety of suitable materials/matrixes capable of adapting to and addressing these challenges. In this review, we discuss and highlight the key developments for effective removal and immobilization of <sup>99</sup>Tc liquid waste in inorganic waste forms. Specifically, we review the synthesis, characterization, and application of materials for the targeted removal of <sup>99</sup>Tc from (simulated) waste solutions under various experimental conditions. These materials include (i) layered double hydroxides (LDHs), (ii) metal-organic frameworks (MOFs), (iii) ion-exchange resins (IERs) as well as cationic organic polymers (COPs), (iv) surface modified natural clay materials (SMCMs), and (v) graphene-based materials (GBMs). Second, we discuss some of the major and recent developments toward <sup>99</sup>Tc immobilization in (i) glass, (ii) cement, and (iii) iron mineral waste forms. Finally, we present future challenges that need to be addressed for the design, synthesis, and selection of suitable matrixes for the efficient sequestration and immobilization of <sup>99</sup>Tc from targeted wastes. The purpose of this review is to inspire research on the design and application of various suitable materials/matrixes for selective removal of <sup>99</sup>Tc present globally in different radioactive wastes and its immobilization in stable/durable waste forms.

Biogenic Synthesis of Fluorescent Carbon Dots (CDs) and Their Application in Bioimaging of Agricultural Crops Fluorescent nanoparticles have a transformative potential for advanced sensors and devices for point-of-need diagnostics and bioimaging, bypassing the technical burden of meeting the assay performance requirements. Carbon dots (CDs) are rapidly emerging carbon-based nanomaterials. Regardless of their fate, they will find increasing applications. In this study, a simple approach for synthesizing CDs from fruit peels was developed. The CDs were fabricated from Annona squamosa (L.) peels using a carbonization technique through microwave-assisted hydrothermal digestion at temperatures around 200 °C. Synthesized CDs were detected using a UV transilluminator for the preliminary confirmation of the presence of fluorescence. UV–Vis spectrophotometry (absorbance at 505 nm) analysis, zeta potential measurement (−20.8 mV), nanoparticles tracking analysis (NTA) (average size: 15.4 nm and mode size: 9.26 nm), photoluminescence, and Fourier transform infrared (FT-IR) analysis were used to identify the capping functional groups on the CDs. The total quantum yield exhibited was 8.93%, and the field emission scanning electron microscopy (FESEM) showed the size range up to 40 nm. The germinating mung bean (Vigna radiata (L.)) seeds were incubated with biogenically synthesized CDs to check the absorption of CDs by them. The fluorescence was observed under a UV-transilluminator in the growing parts of seeds, indicating the absorption of CDs during the germination, development, and growth. These fluorescent CDs could be used as a bioimaging agent. This novel method of synthesizing CDs was found to be eco-friendly, rapid, and cost-effective.

A review on transport characteristics and bio-sensing applications of silicene Silicene, a silicon counterpart of graphene, has been predicted to possess Dirac fermions. The effective spin-orbit interaction in silicene is quite significant compared to graphene; as a result, buckled silicene exhibits a finite band gap of a few meV at the Dirac point. This band gap can be further tailored by applying in plane strain, an external electric field, chemical functionalization and defects. This special feature allows silicene and its various derivatives as potential candidates for device applications. In this topical review, we would like to explore the transport features of the pristine silicene and its possible nano derivatives. As a part of it, Thermoelectric properties as well as several routes for thermoelectric enhancement in silicene are investigated. Besides, the recent progress in biosensing applications of silicene and its hetero-structures will be highlighted. We hope the results obtained from recent experimental and theoretical studies in silicene will setup a benchmark in diverse applications such as in spintronics, bio-sensing and opto-electronic devices.

Computational approaches to delivery of anticancer drugs with multidimensional nanomaterials Functionalized nanotubes (NTs), nanosheets, nanorods, and porous organometallic scaffolds are potential in vivo carriers for cancer therapeutics. Precise delivery through these agents depends on factors like hydrophobicity, payload capacity, bulk/surface adsorption, orientation of molecules inside the host matrix, bonding, and nonbonding interactions. Herein, we summarize advances in simulation techniques, which are extremely valuable in initial geometry optimization and evaluation of the loading and unloading behavior of encapsulated drug molecules. Computational methods broadly involve the use of quantum and classical mechanics for studying the behavior of molecular properties. Combining theoretical processes with experimental techniques, such as X-ray crystallography, NMR spectroscopy, and bioassays, can provide a more comprehensive understanding of the structure and function of biological molecules. This integrated approach has led to numerous breakthroughs in drug discovery, enzyme design, and the study of complex biological processes. This short review provides an overview of results and challenges described from erstwhile investigations on the molecular interaction of anticancer drugs with nanocarriers of different aspect ratios.

Investigation on the size and percentage effects of magnesium nanoparticles on thermophysical properties of reinforced calcium phosphate bone cement by molecular dynamic simulation In recent years, bone materials and cement innovation have made extraordinary strides. Calcium phosphate cement (CPC) regenerates body tissues and repairs bone and dental defects. Since the presence of nanoparticles (NPs) increased the initial cement strength in terms of the reduction of porosity, magnesium (Mg) NPs were used because of their unique properties. In this study, the effects of various Mg NP percentages and sizes on reinforced cement thermal behavior and mechanical behavior are investigated using the molecular dynamics (MD) simulation method. The changes of Young's modulus (YM), maximum temperature (MT), and ultimate strength (US) were investigated for this reason. The US, YM, and MT of the reinforced cement sample improved from 0.879 to 0.171 MPa to 1.326 and 0.255 MPa, respectively, and from 1321 to 1403 K by raising the NPs percentage to 4%. The radius increase of NPs to 16 Å enhanced the US, YM, and MT to 0.899 MPa, 0.179 MPa, and 1349 K. The MT decreased to 1275 K. The quantity and size of the Mg NPs significantly enhanced the mechanical behavior of the finished cement, according to the findings.

Nanomaterials for Targeting Liver Disease: Research Progress and Future Perspectives Liver disease is a significant global health issue that affects the liver and contributes to approximately 2 million deaths worldwide each year. Although treatment options including surgery and medication are available, effective treatment remains a challenge because of limitations of the traditional drug-delivery methods, such as uneven and nonspecific drug distribution, which lead to negative effects on healthy tissues and a reduction in drug bioavailability. Nanotechnology provides a promising solution for targeted drug delivery to the liver, which has unique anatomical and physiological structures that render it an ideal target for nanomedicine. Several categories of nanomaterials, including inorganic nanomaterials, polymer nanomaterials, and multifunctional nanoparticles (NPs), have been studied as potential agents for targeting this organ in the context of liver diseases. Using surface modification and functionalization, nanomaterials can be selectively targeted to liver tissue or hepatocytes, thus delivering drugs, and enhancing their efficacy while minimizing their side effects. Nanomaterials exhibit numerous benefits; however, their stability and toxicity pose potential risks to living organisms result in adverse effects, such as protein adsorption, and inflammation. Despite the challenges inherent to the development of nanomaterials, ongoing research and development have a great potential for the liver-targeted treatment of liver diseases through the use of nanotechnology. In this review, we first describe the nanomaterials used to target liver diseases, i.e., metallic NPs, ceramic nanomaterials, micelles, polysaccharides, liposomes, dendrimers, carbon nanotubes, and multifunctional NPs. Moreover, the mechanisms for nanomaterials target liver disease are discussed. Finally, this review discusses the current challenges and prospects for future research directions in this field.

Preparation of graphene oxide-doped silica aerogel using supercritical method for efficient removal of emerging pollutants from wastewater Emerging pollutants and a large volume of unused dyes from the textile industry have been contaminating water bodies. This work introduces a scalable approach to purifying water by the adsorption of Acid green 25 (AG), Crystal Violet (CV), and Sulfamethoxazole (SMA) from an aqueous solution by graphene oxide (GO) doped modified silica aerogel (GO-SA) with supercritical fluid deposition (SFD) method. Characterization of GO-SA using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), high-resolution scanning electron microscopy (HR-SEM), thermogravimetric analysis (TGA), and Brunauer-Emmett-Teller (BET) adsorption isotherms revealed the improvement in the adsorbent surface area, and its textural properties. The high removal percentages observed in most of the experimental runs provide evidence of the excellent performance of the adsorbent towards the anionic and cationic dyes along with the antibiotic. The adsorption isotherm and kinetics showed that the Langmuir isotherm and pseudo-second-order kinetic models could explain adsorption. The adsorbent holds a higher adsorption capacity for SMA (67.07 mg g<sup>-1</sup>) than for CV (41.46 mg g<sup>-1</sup>) and AG (20.56 mg g<sup>-1</sup>) due to the higher hydrophobicity that interacts with the hydrophobic adsorbent. The GO-SA successfully removed AG, CV, and SMA with removal percentages of 98.23%, 98.71%, and 94.46%, respectively. The parameters were optimized using Central Composite Design (RSM-CCD). The prepared aerogel showed excellent reusability with a removal efficiency of > 85% even after 5 cycles. This study shows the potential of GO-SA adsorbent in textile and other wastewater purification.
