Raman spectroscopy has capability for fingerprint molecular identification with high sensitivity if weak scattering signal can be enhanced by several orders of magnitudes. Herein, we report a heterostructure-based surface-enhanced (SERS) platform using 2D graphene oxide (GO) and 0D plasmonic gold nanostar (GNS), enhancement factor (EF) in the range ∼1010 via light–matter matter–matter interactions. The current manuscript reveals huge heterostructure materials occurring both electromagnetic...
Intermetallics with crystals derived from body-centered cubic structures are promising materials to enhance the performance and high temperature capability of high-strength alloys both as matrix strengthening precipitates. Given ordered nature these materials, defect that ultimately mediate plasticity can be complex strongly dependent on processing vis-à-vis extent disorder inherited phases. Here, we elucidate elementary characteristics in Heusler (L21) intermetallic MnCu2Al investigated by...
Multiphase $\mathrm{bcc}/B2$-based alloy systems have recently received considerable attention because their microstructures are often remarkably similar to the $\ensuremath{\gamma}/{\ensuremath{\gamma}}^{\ensuremath{'}}$ microstructure of Ni-based superalloys. The underlying plastic deformation mechanisms bcc-based intermetallics, however, not well understood across composition space where they thermodynamically stable. Within this contribution, we analyze $B2$ intermetallics develop a...
The emergence of Alpha, Beta, Gamma, Delta, and Omicron variants severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for several million deaths up to now. Because the huge amount vaccine escape mutations in spike (S) protein different variants, design material combating SARS-CoV-2 very important our society. Herein, we report on a human angiotensin converting enzyme (ACE2) peptide-conjugated plasmonic-magnetic heterostructure, which has capability magnetic separation,...
Solar cells fabricated from sustainable quantum dot materials are currently not commercially available, but ongoing research provides a steady increase in efficiency and stability of laboratory devices. In this work, the first germanium solar cell made with gas aggregation nanoparticle source is presented. UV–vis spectroscopy reveals confinement, spectral response Grätzel‐type confirms presence large small band gap optical absorption due to mix particle sizes. Some particles enough have...
The Heulser intermetallic ${\mathrm{MnAu}}_{2}\mathrm{Al}$ is shown to undergo a dramatic change in net magnetization response plastic deformation. A mechanism proposed involving antiferromagnetic interactions the otherwise ferromagnetic compound (when ordered) that arise due chemical changes at antiphase boundaries created by coupling between and magnetic order across likely occur other ordered systems may provide an explanation for anomalous behavior several systems, including Heusler...
Decorating thin-film solar cells with plasmonic nanoparticles is being pursued in order to improve device efficiency through increased scattering and local field enhancement. Gold are particularly interesting due their chemical inertness plasmon resonance the visible range of spectrum. In this work, gold fabricated by a gas aggregation nanoparticle source embedded a-Si (a commercial cell material) studied using X-ray photoelectron spectroscopy, transmission electron microscopy, energy-loss...
Phase separation---and conversely, the propensity for solid-solution formation---in half-Heusler ($XYZ$) and Heusler ($X{Y}_{2}Z$) compounds is suggested from first-principles electronic-structure-based modeling to be strongly linked electronic behavior of end-members. Alloying between distinct pairs possible at accessible processing temperatures when two end-members are either isoelectronic or metallic. The formation a band gap in semiconducting associated with significant stabilization....
Abstract A new process called nanofunctionalization was successfully used to control the solidifying microstructure during additive manufacturing and produce crack-free 7000 6000 series aluminum alloys for first time.
Ensuring reliably repeatable dependency installation has long been an unsolved problem for many Python projects. Pinning dependencies via setup.py and requirements.txt historically met with extra work unexpected results, particularly when managing the of dependencies. Thanks to PEP 518, projects can now more easily manage new pyproject.toml file specification. In its wake, a number useful tools have arisen that use this provide enhanced resolution, including Poetry, Hatch, Pipenv. Attendees...
Abstract The method of radioactive tracers was used for measurement the depth liquid zone. experimental work run under common technological conditions. Two techniques marking steel were applied: – motion and position capsules with suitable radionuclides detected by radiometric method, distribution lead marked 124Sb in peak segregation zone evaluated autoradiographic method. auloradiograms made on sections prepared from slabs. determined basis evaluation auloradiograms. It established, that...
