So whether you’re dyeing your hair for self-expression, hair experimentation or just plain fun, you can now do it with confidence at home. Read on for nine life-changing Korean hair color treatments to try.

Surface-enhanced Raman scattering (SERS) has been a promising analytical technique for the detection of trace species because of its remarkable advantages, namely, it is sensitive, it is nondestructive, it has a quick response time, and it provides unique information on the species (1–3). Studies on noble metal nanostructures, such as Au, Ag, and Cu, indicate that the tremendous electromagnetic field enhancement at the hotspots greatly increases the sensitivity of SERS (4). However, the SERS effect based on electromagnetic field enhancement has no selectivity for Raman reporters, resulting in complicated signal outputs generated by unexpected interactions (5). Recently, another mechanism, chemical enhancement mechanism (CM), which is related to the formation of charge transfer (CT) states between the adsorbed molecules and the nanoparticles (NPs) (6), has attracted more attention. Compared with SERS, which is based on electromagnetic field mechanism, this unique method always demonstrates high molecule selectivity. Most substrates based on CM show stable and reproducible SERS signals without agglomeration, which is different from those obtained from noble metals. Moreover, the CM-based substrate exhibits good biocompatibility without cytotoxic outcomes. Thus, various new materials have been developed to investigate CT in plasma-free SERS, such as graphite oxide (GO) and semiconductor materials (7). However, only 10 to 100 enhancements have been achieved by these materials (8, 9), limiting their potential applications for reliable quantitative detection in biological and biomedical analysis and diagnosis. Accordingly, low enhancement factor (EF) values prevent further applications of CM-based SERS substrates.

Finally, the set of semi perm tools help customers mix “beautifully obnoxious colors” without staining their hands. The set contains two pairs of black gloves, a tinting brush, and a mixing bowl — with the GDY logo emblazoned on the side.

Modern archeology, with its fastidious excavations, seemed to offer a promising model. There were also Victorian manuals on the material composition of pigments—including “The Chemistry of Paints and Painting,” by Arthur Herbert Church, one of the first scientists to hold a position at the Royal Academy of Arts, in London. In 1928, as the director of the Fogg, Forbes invited a Harvard chemistry professor, Rutherford John Gettens, to create and run a lab in its new building. Gettens’s legacy is a cabinet, near the pigment collection, that contains thousands of slides, each showing how the shade of a paint might age naturally depending on its binding medium: egg yolk, egg white, the whole egg, oils.

Abstract: Systems and methods for providing a Barrier Modulated Cell (BMC) structure with reduced shifting in stored memory cell resistance levels over time are described. The BMC structure may comprise a reversible resistance-switching memory element within a memory array comprising a first conductive metal oxide (e.g., titanium oxide) in series with an alternating stack of one or more layers of an amorphous low bandgap material (e.g., germanium) with one or more layers of a second conductive metal oxide (e.g., aluminum oxide). The BMC structure may include a barrier layer comprising a first conductive metal oxide, such as titanium oxide or strontium titanate, in series with a germanium stack that includes a layer of amorphous germanium or amorphous silicon germanium paired with a second conductive metal oxide. The second conductive metal oxide (e.g., aluminum oxide) may be different from the first conductive metal oxide (e.g., titanium oxide).
