AbstractAcidity at surface of cancer cells is a hallmark of tumor microenvironments, which does not depend on tumor perfusion, thus it may serve as a general biomarker for targeting tumor cells. We used the pH (low) insertion peptide (pHLIP) for decoration of liposomes and niosomes. pHLIP senses pH

AbstractAn optical diode structure with two dislocated parallel metallic gratings is proposed and investigated numerically. Dichroic optical diode transmission is realized in this structure, i.e., optical diode effect is observed in two wavebands corresponding to inverse transmission directions. In

Abstract Living tissues combine high strength with autonomous self‑repair. To emulate this synergy, we have developed poly(acrylic acid)/surface‑modified boron nitride nanosheet (PAA/BNNS‑NH₂) composite hydrogels assembled through dual physical interactions: iron‑mediated carboxyl coordination and h

AbstractWe propose a novel one-step exposure method for fabricating three-dimensional (3D) suspended structures, utilizing the diffraction of mask patterns with small line width. An optical model of the exposure process is built, and the 3D light intensity distribution in the photoresist is calculat

AbstractWe examine how a metal substrate reshapes the magnetic dipole (MD) resonance of a silicon nanosphere (NS) illuminated by a focused azimuthally polarized (AP) beam. The MD excited in the Si NS and its image dipole induced by the substrate are out of phase, leading to destructive interference

AbstractRecent advances in nanotechnology have highlighted the promise of magnetic graphene-based composites for the remediation of antibiotic pollutants. In this study, we fabricated a MnFe₂O₄ nanoparticle‑decorated reduced graphene oxide (MnFe₂O₄/rGO) nanocomposite using a single‑step, scalable s

Abstract Serum myoglobin rises within 1–2 h after an acute myocardial infarction (AMI), making it a critical early biomarker. We present a plasmonic immunoassay that exploits enzyme‑mediated localized surface plasmon resonance (LSPR) changes of gold nanorods (AuNRs) to quantify myoglobin with a line

AbstractThis study investigates how cryogenic cycling treatment (CCT) rejuvenates a Zr50Cu40Al10 bulk metallic glass (BMG). When cast at a high temperature, the alloy forms a homogeneous amorphous matrix that does not generate internal stress during CCT, preventing rejuvenation. Conversely, casting

AbstractLead‑halide perovskites are celebrated for their exceptional optical absorption, long carrier lifetimes, and high diffusion lengths, making them ideal for photodetectors. Traditional metal‑oxide, metal‑sulfide, and 2D‑material devices deliver respectable responsivity but often suffer from hi

AbstractUsing first‑principles calculations, we systematically investigate the stability, electronic structure, optical absorption, and the tunability of bilayer α‑GeTe through changes in interlayer spacing and the application of external electric fields. The van der Waals (vdW) bilayer exhibits an

AbstractWe report a scalable synthesis of hollow polyaniline (PANI) micro/nanospheres via soft‑templated monomer polymerization in an alkaline medium using Triton X‑100 micelles. The resulting nanostructure exhibits rapid, high‑capacity adsorption of hexavalent chromium (Cr(VI)) across a broad pH sp

Abstract To elevate the safety of ammonium nitrate‑based munitions, we employed a melamine‑urea‑formaldehyde (MUF) binder to fabricate green polymer‑bonded explosives (GPBXs) with three benchmark nitramine cores—HMX, RDX, and CL‑20—using interfacial polymerization. For comparison, identical composit

AbstractInefficient Mg-induced p-type doping has been remained a major obstacle in the development of GaN-based electronic devices for solid-state lighting and power applications. This study reports comparative structural analysis of defects in GaN layers on freestanding GaN substrates where Mg inco

AbstractIdentifying atomically thin two‑dimensional (2D) semiconductors that combine a sizable band gap with high carrier mobility remains a key challenge in materials science. Recent synthesis of layered SiAs single crystals has shown that few‑layer SiAs can be mechanically exfoliated, suggesting t

AbstractThe energy band alignment at the multilayer-MoS2/ZrO2 interface and the effects of CHF3 plasma treatment on the band offset were explored using x-ray photoelectron spectroscopy. The valence band offset (VBO) and conduction band offset (CBO) for the MoS2 /ZrO2 sample is about 1.87 eV and 2.49

AbstractThe highly dispersed silver nanoparticle-loaded poly(styrene-co-acrylic acid) nanocomposites (nAg@PSA) were prepared and characterized by transmission electron microscopy and thermogravimetry. The amount and distribution of colloidal silver per particle were related to the dissociation ratio

AbstractFeOOH nanosheets were uniformly grown on porous diatomite through a simple two‑step hydrothermal route. Subsequent calcination under controlled atmospheres produced α‑Fe₂O₃ and γ‑Fe₂O₃ nanostructures, allowing systematic comparison of their electrochemical behavior in 1 M Na₂SO₄. The diatomi

AbstractSuperparamagnetic iron oxide nanoparticles (SPIO) were synthesized and tested as carriers for antigen delivery into dendritic cells (DCs). SPIO‑laden DCs showed excellent biocompatibility and enhanced ovalbumin (OVA) cross‑presentation. We prepared positively charged SPIO/A⁺ (APTS‑coated) an

AbstractPlatinum nanoparticles remain the benchmark catalyst for direct methanol fuel cells (DMFCs), yet their high cost, sluggish methanol oxidation kinetics, and CO poisoning limit practical use. Recent advances focus on Pt alloys (e.g., Pt‑Ru, Pt‑Ni, Pt‑Co, Pt‑Sn) and advanced carbon supports (M

AbstractHigh-brightness white-light-emitting diodes (w-LEDs) with excellent color quality is demonstrated by using nontoxic nanomaterials. Previously, we have reported the high color quality w-LEDs with heavy-metal phosphor and quantum dots (QDs), which may cause environmental hazards. In the presen
