Rechargeable batteries (RBs) have become the dominant technology in the energy storage market due to their high energy density, long cycle life, and versatility in applications ranging from portable electronics to electric vehicles. However, the performance of RBs heavily depends on the anode material in which conventional graphite anodes face limitations in capacity and rate c…

In this work, we demonstrate that the fluorescence of aqueous graphene oxide (GO) suspensions is significantly quenched upon the introduction of silver ions (Ag⁺). The extent of quenching exhibits a clear dependence on both Ag⁺ concentration and interaction time. Comprehensive characterization using TEM, SEM, AFM, and UV-visible spectroscopy confirms that Ag⁺ ions unde…

The role of vesicular systems in the field of drug delivery has led to increased research in the optimization of these novel delivery methods. Niosomes are bilayer structures that are capable of encapsulating lipophilic and hydrophilic compounds. In this study, niosomal systems formed from either Span 60 or Tween 60 non-ionic surfactants were investigated through experimental w…

Fast and accurate quantification of the size and morphology of nanoparticles in electron microscopy images is essential for advancing heterogeneous catalysis and energy-conversion research, yet manual segmentation remains the main approach, which is time-consuming, subjective, and challenging to scale. Herein, we present an accessible and efficient deep learning model integrate…

Here, we synthesized an innovative nanocomposite film (BPAZ) by blending bacterial cellulose (BC) with polyvinyl alcohol (PVA) and reinforced it with Ag/ZnO nanoparticles. Structural and morphological analyses confirmed the uniform dispersion of Ag/ZnO in the BC/PVA matrix. The BPAZ films exhibited enhanced antibacterial and antioxidant properties compared with the BC/PVA film.…

The present study was conducted to determine the size of gold nanoparticles and their respective number concentrations in mono-, bi- and trimodal suspensions using dynamic light scattering (DLS), particle tracking analysis (PTA), scanning electron microscopy (SEM) and single particle inductively coupled plasma mass spectrometry (spICP-MS). This intercomparison approach aimed to…

This study systematically screened deproteinization conditions for the selective and quantitative recovery of methoxy poly(ethylene glycol) (mPEG) and model PEGylated nanomedicines, either intact or as mPEG components, from full human serum and full rat liver lysate. Although mPEG and all PEGylated nanosystems were a priori soluble under all the deproteinization conditions inve…

An atomic-level understanding of Ag-Au heterostructures is crucial for elucidating the catalytic and plasmonic properties of Ag-Au bimetallic nanostructures, as well as their potential applications. In this study, we investigated the surface structures of Ag formed on an Au(111) surface using scanning tunneling microscopy (STM) to gain atomic-level insight. When the substrate t…

This work presents a comprehensive study of a core-shell Asymmetric Dopingless Nanotube Tunnel Field Effect Transistor (A-DL-NT-TFET), designed to overcome the limitations of conventional TFET architectures. The device employs asymmetric gate design to enhance tunneling, doping-less operation to remove abrupt junctions and ensure uniform control, and a cylindrical nanotube geom…

Phthalic acid esters (PAEs) are high-volume manufacturing organic materials used in plasticisers to increase the elasticity of the core polymer. They are reported to spread into the surroundings from plastic products and are now a global environmental contaminant. Several environmental sources, particularly water, have been examined for phthalate contaminant levels. These subst…

Antimicrobial resistance and the presence of potent microbial entities in water and biological matrices have been major challenges to traditional chemical and thermal disinfection techniques. Although semiconductor-based photocatalysis is a promising and non-invasive oxidative technology, the use of pure photocatalysts is often restricted by their large optical bandgaps and hig…

Silicene, a buckled honeycomb-lattice allotrope of two-dimensional (2D) silicon, has attracted strong interest as a candidate for post-silicon electronics, owing largely to its compatibility with existing silicon-based fabrication methods and its theoretically predicted massless Dirac fermions. However, the material suffers from three persistent obstacles that prevent its devic…

Nanohydroxyapatite (nHAp) is a promising biomaterial due to its structural similarity with the mineral phase of natural bone, high bioactivity, and broad applications in biomedical fields. Although this field is growing rapidly, there is no dedicated review which systematically offers an overview on toxicity and bio-safety profile of nHAp composites. The researchers reported th…

As the energy storage ecosystem evolves beyond lithium, MXenes, a versatile family of 2D materials derived from MAX phases, have emerged as promising candidates for next-generation energy storage electrodes due to their tunable surface chemistry, large interlayer spacing, and excellent electronic conductivity. In this work, we use density functional theory to investigate Ti₃…

In this study, a plasmonic chip with a deep-hole array (DHA) structure enhanced fluorescence, enabling highly sensitive detection of targets via inverted fluorescence microscopy. Inverted microscopes are particularly suitable for detecting membrane proteins at the cell-substrate interface, where the cell membrane spreads in a single plane. Fluorescence enhancement should be hom…

TNBC defying conventional therapies and the rapid increase in antimicrobial resistance disarming powerful antibiotics demand urgent clinical intervention. The current research study explored a strategy to target TNBC and drug-resistant pathogens using flavonoid (morin)-induced gold nanoparticles (MorAunps) tethered with folic acid and chitosan (CH/FA-MorAunps) for enabling targ…
