AbstractWe report a simple oleic‑acid mediated hydrothermal route to synthesize ~19 nm Sc₂O₃:Er³⁺,Yb³⁺ nanoparticles (NPs). X‑ray diffraction, TEM, and upconversion luminescence (UCL) measurements confirm a cubic bixbyite host with excellent crystallinity. Under 980 nm excitation, the hydrothermal

AbstractMatrix metalloproteinase‑7 (MMP‑7) drives tumour invasion by cleaving extracellular matrix and peptide bonds between alanine and leucine. Here we present a Pd‑functionalized carbon nanocomposite (Pd‑CNC) that acts as a high‑impedance enhancer in an amperometric MMP‑7 biosensor. Palladium n

Abstract Red‑emitting carbonized polymer dots (CPDs) were fabricated from p-phenylenediamine (p-PD) aqueous solution under the catalytic influence of sulfuric acid (H2SO4). The resulting SA‑CPDs (average diameter ≈5 nm) exhibited the brightest photoluminescence among acids tested, with a quantum yi

AbstractIn this study we demonstrate that nanostructured carbon composites, especially multi‑walled carbon nanotubes (MWCNTs) and their mixtures, can replace platinum (Pt) as counter‑electrode (CE) materials in dye‑sensitized solar cells (DSSCs). Using a simple screen‑printing process, we deposited

Abstract Silicon is a compelling anode material for sodium‑ion batteries (NIBs) because of its high theoretical capacity (954 mAh g⁻¹). Here we show that mesoporous silicon microspheres (MSMs) with uniformly distributed pores (1–10 nm) can be fabricated through an in‑situ magnesiothermic reduction o

AbstractWe engineered thermal interface materials (TIMs) by combining reduced graphene oxide (RGO) and three‑dimensional graphene networks (3DGNs). The 3DGNs create a high‑conductivity phonon network, while RGO bridges the graphene and epoxy resin (ER) matrix, especially when its surface is enriched

Abstract Wearable electronics demand inorganic semiconductors that can be fabricated on flexible, inexpensive substrates. In this work, we present a novel ultraviolet (UV) photodetector (PD) that incorporates a dense array of ZnO microwires (MWs) embedded within a polyvinyl alcohol (PVA) film. The d

Abstract Precise deposition of electrospun fibers remains a major challenge for organ hemostasis. We present an electric‑field‑modified e‑spinning system that incorporates a metal cone at the nozzle, enabling controllable fiber placement. The deposition area is tunable by altering the cone size, a b

AbstractWe investigated how 40‑ and 80‑nm gold nanoparticles (AuNP) functionalized with cationic branched polyethylenimine (BPEI), anionic lipoic acid (LA), or neutral polyethylene glycol (PEG) interact with the human hepatocellular carcinoma (HCC) cell line C3A, both in the presence and absence of

AbstractMalignant tumours remain a leading cause of mortality worldwide, and the ability to detect early disease and predict metastatic spread is critical for selecting the most effective treatment strategy. Integrin αvβ3 is a well‑validated biomarker of tumour angiogenesis, making it an attractive

Abstract Black phosphorene, a two‑dimensional monolayer of phosphorus, has attracted attention for its direct bandgap, high carrier mobility, and mechanical flexibility. Using spin‑polarized density functional theory, we investigated how 12 transition‑metal (TM) atoms—Fe, Co, Ni, Cu, Ru, Rh, Pd, Ag,

AbstractSilicon nanowires (SiNWs) with excellent light trapping properties have been widely applied in photovoltaic devices, which provide opportunities for boosting the photons harvested by Si. However, the photoexcited carriers are easily trapped and recombined by high-density surface defects due
