Article Abstract

Presolar SiC and graphite grains are the grain types whose isotopic signatures have been extensively studied. Isotopic compositions of light and intermediate elements in single grains have been analyzed mostly using secondary ion mass spectrometry. Detailed information about nucleosynthetic conditions can be obtained from isotopic compositions of heavy elements. Isotopic compositions of heavy elements in SiC and graphite grains have been analyzed using resonant ionization mass spectrometry. Analyses of heavy elements and noble gases are likely to produce new insights into presolar grains using newly-developed instruments.

An advanced electrochemical immunosensor platform was designed for the precise quantification of cortisol. The sensor design integrates graphene oxide-silicon carbide (GO-SiC) nanocomposites onto a glassy carbon electrode (GCE). Denatured bovine serum albumin (d-BSA) and an anti-cortisol antibody were immobilized on the GO-SiC/GCE surface as part of the immunosensor's design.

The intervalley coherent (IVC) phase in graphene systems arises from the coherent superposition of wave functions of opposite valleys, whose direct microscopic visualization provides pivotal insight into the emergent physics. Here, we successfully visualize the IVC phase in a heterostructure of monolayer PtSe_{2} and bilayer-graphene (BLG) on graphite. Using spectroscopic imaging scanning tunneling microscopy, we observe a sqrt[3]×sqrt[3] modulation pattern superimposed on the higher-order moiré superlattice of the heterostructure, which correlates with a gap-opening feature around the Fermi level and displays an antiphase real-space conductance distribution of the two gap edges.

The analysis studies impact of nanocomposites (NCs) to improve thermal efficiency in hydrogen liquefaction while decreasing energy consumption. The study uses an innovative combination of experimental investigations coupled with machine learning methods to identify superior nanocomposites for their peak performance characteristics. Experimental data measurement of key thermophysical characteristics are estimated by using Pearson's-r correlation analysis.

Research on raw materials for AlO-SiC-C refractory castables used in blast furnace troughs is relatively well established. However, gaps remain in both laboratory and industrial trials concerning the performance of castables incorporating SiC-modified flake graphite and alternative carbon sources. This study investigated the sintering behavior, mechanical properties, and service performance of AlO-SiC-C castables utilizing varying contents of modified flake graphite, pitch, and carbon black as carbon sources.

Engineering thermal strain is crucial for tuning the properties and functionalities of transition metal dichalcogenides (TMDs). Thermal strain arises from the thermal expansion coefficient (TEC) mismatch between TMDs and substrates, but conventional substrates often induce inhomogeneous broadening in the electronic structure, mainly due to surface roughness and charged impurities. Here, we demonstrate uniform thermal strain in monolayer WSe via van der Waals epitaxy on graphene/SiC(0001) substrates.
