AbstractIn the present work, we report on the in-plane electrical transport properties of midwave (MWIR) and longwave infrared (LWIR) InAs/GaSb type-II superlattices (T2SLs) grown by molecular beam epitaxy (MBE) system on GaAs (001) substrate. The huge lattice mismatch between the T2SL and GaAs subs

AbstractWe introduced a Joule‑Heating Decomposition (JHD) approach that applies a direct current to a highly doped 4H‑SiC substrate, enabling the epitaxial growth of multi‑layer graphene (MLG) on the Si‑terminated (0001) surface in just a few minutes. Raman spectroscopy was employed to quantify how

AbstractMagnesium alloys are attractive for aerospace, automotive and electronics due to their low density and high strength-to-weight ratio. However, their rapid corrosion and wear under operational conditions limit widespread use. Electroless nickel‑phosphorus (Ni‑P) coatings provide a cost‑effec

Abstract We employ spin‑polarized density functional theory to investigate vanadium (V) adsorption on both pristine Cu(111) and graphene‑covered Cu(111) (Gra/Cu(111)). Two coverages—0.11 ML (1/9 ML) and 1 ML—are examined. On clean Cu(111), V prefers an interstitial site beneath the surface for both

AbstractWe report the successful synthesis of Bi‑doped n‑type polycrystalline SnSe via a hot‑pressing route. The samples exhibit pronounced anisotropy in electrical and thermal transport, attributed to a preferential (h00) grain orientation along the pressing axis. At 773 K, the 8 % Bi‑doped specime

AbstractThis study reports the fabrication of ZnO/porous anodic alumina (PAA) composite films via a two‑step anodization followed by a sol‑gel deposition of ZnO. The films were systematically characterized using XRD, TG/DTA, FT‑IR, SEM, TEM, SAED, and water contact angle (CA) measurements. The ant

Abstract A simple, room‑temperature route has been developed to produce ZnO nanoparticles directly from highly concentrated aqueous zinc chloride (65–80 wt %) and alkaline solutions in the presence of glycerol as a stabilizer. The ZnCl₂ concentration and the glycerol‑to‑Zn²⁺ molar ratio strongly inf

AbstractWe present a scanning tunneling microscopy (STM) investigation of Au thin films on Ru(0001) with nominal thicknesses of 5 and 9 monolayers (ML), deposited at 300 K and subsequently annealed at 1050 K. The 9 ML film exhibits a new laterally periodic superstructure: a subtle height rippling of

Abstract\nWe engineered structural color by combining electrospinning of ZnO nanofiber seed layers with precisely timed hydrothermal growth. Aligned fibers produce optical switching patterns whose appearance varies with the incidence angle of light. Replication in polydimethylsiloxane (PDMS) demonst

AbstractPower scaling in broad area quantum cascade laser (QCL) usually leads to the deterioration of the beam quality with an emission of multiple lobes far-field pattern. In this letter, we demonstrate a tapered QCL array integrated with Talbot cavity at one side of the array. Fundamental supermod

AbstractMicro‑scale energy devices, such as electric initiation systems, demand compact, high‑energy, and low‑ignition‑temperature materials. In this study, we developed a reactive Al/PTFE nanolaminate by alternating magnetron‑sputtered aluminum (Al) and polytetrafluoroethylene (PTFE) layers, creati

Abstract We employed density functional theory to explore how alkali‑metal adsorption alters the electronic and optical behavior of graphene‑like gallium nitride (g‑GaN). All examined systems proved thermodynamically stable, with the hexagonal ring center (TM) emerging as the most favorable adsorpti

AbstractHigh‑density inorganic nanoparticles are emerging as powerful agents in radiation‑based medicine, from X‑ray imaging to radiotherapy dose enhancement. We report a scalable, aqueous synthesis that delivers 2–3 nm iridium nanoparticles (IrNPs) through borohydride reduction of iridium(III) chlo

AbstractStimuli‑responsive polymers are increasingly valuable in biomedical and advanced material applications. Here, we report a cross‑linked polymer, poly(oligo(ethylene glycol) diacrylate‑methacrylic acid) (P(OEGDA‑MAA)), prepared by precipitation polymerization. The material displays a lower‑cri

AbstractSilver (Ag) nanoparticles (Ag NPs) of controlled size and concentration were incorporated into a TiO₂ compact layer via a polyol synthesis route to enhance the performance of perovskite solar cells (PSCs). X‑ray diffraction confirmed that the anatase TiO₂ lattice remained unchanged after Ag

AbstractPlasmonic metallic nanoparticles are coupled to the organic solar cells to overcome the trade-off between the light absorption and carrier collection. They are usually located inside or outside of the active layers. However, no detailed comparison was reported on the light absorption differe

AbstractTitania nanotubes (TNTs) were fabricated via chemical processing and rapid‑breakdown anodization (RBA), yielding three distinct morphologies and crystal phases. Wall thicknesses below 30 nm dramatically lower thermal conductivity through phonon confinement, reduced mean free paths, and enha

AbstractVariability in resistive random access memory cell has been one of the critical challenges for the development of high-density RRAM arrays. While the sources of variability during resistive switching vary for different transition metal oxide films, the stochastic oxygen vacancy generation/re

AbstractIn this study, several simple equations are suggested to investigate the effects of size and density on the number, surface area, stiffening efficiency, and specific surface area of nanoparticles in polymer nanocomposites. In addition, the roles of nanoparticle size and interphase thickness

AbstractThermally reduced graphene oxide (TRG) composites were engineered with controllable interlayer spacing by intercalating the anionic surfactant sodium dodecyl sulfate (SDS). A simple post‑processing step involving rinsing the SDS‑intercalated TRG (TRGS) with the ionic liquid (IL) 1‑ethyl‑3‑me
