NEW YORK (AP) — Many companies including McDonald’s and Kellogg are purging artificial colors from their foods, but don’t expect your cheeseburgers or cereal to look much different.

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.

Abstract: A thermal detection system for detecting a thermal profile of an optical window may be used in an airborne body that contains a sensor system. The system may include a thermal imager arranged within the airborne body for imaging a portion of the optical window and the portion may coincide with an optical path of the sensor system. The system may further include a processor in communication with the thermal imager for receiving images of the portion and determining a thermal gradient of the portion. The processor may be configured to apply corrections to active optical elements of the sensor system to accommodate for adverse thermal effects on the optical sensor that interferes with the sensor system performance.

Abstract: A method for operating a relay node during a handoff from a first controller to a second controller includes receiving a first instruction from the first controller to discontinue using a first set of wireless backhaul link resources allocated to the relay node by the first controller and to temporarily use a second set of wireless backhaul link resources dedicated by the second controller. The method also includes receiving a second instruction from the second controller to discontinue using the second set of wireless backhaul link resources and to begin using a third set of wireless backhaul link resources allocated to the relay node by the second controller.

In total, the collection is massive, consisting of one eyeshadow palette, one highlighter palette and four highlighter singles, one Super Shock Shadow vault, one kit, and six shadow singles, eight jelly shadows, nine body glitters, four lip bundles, a liquid lipstick vault, a makeup bag, and a partridge in a pear tree. I’m joking about that last one, but seriously — this line has a lot going on, and it’s all so, so good. Starting with the Chasing Rainbows Pressed Powder Shadow Palette ($20, colourpop.com), a 15-pan palette which features the perfect ratio of wearable neutrals and shimmery statement shades.

CHEESE Boar’s Head, Cabot, Kraft, Tillamook. Check the packages of most cheddar cheeses, and they’ll likely list an ingredient called annatto, a plant extract commonly used for color.

Once you’ve officially dyed your weave (congrats!), you need to take care of it to keep the color vibrant and the hair healthy. Rez loves using Olaplex to help strengthen the hair, along with weekly (or bi-weekly) hair masks. “Kristin Ess has a wonderful Reconstructive Moisture Mask treatment for weakened or colored hair that will seal strands with moisture,” he says.

And it’s probs not going to fit all your new buys, but feel free to stash a few in the very cute This Is Not A Dream Makeup Bag ($10, colourpop.com), which can double as gift wrap if you’re generous enough to purchase any of these fun goodies for friends this holiday season.

We then investigated the interaction and CT process between GO and TiO2 through TDR spectroscopic measurements. Figure 4E shows an absorption band of MG centered at 750 nm, excited by 633 nm, and assigned to trapped electrons. The electrons decayed quickly owing to the fast charge recombination of electrons and holes generated in MG. Similarly, a broad absorption, assigned to the electrons in MGT and MGT-CuPc, was observed in the 750- to 800-nm region (Fig. 4, F and G). However, both decay lifetimes in MGT and MGT-CuPc (1424.41 and 3112.41 ps, respectively) were much longer than that in MG (246.97 ps), suggesting that the Ti–O–C coordinate bond at the interface acts as an electron trap site, leading to efficient CT. The time profiles of the transient absorption at 750 nm for MG, MGT, and MGT-CuPc were fitted by two-exponential functions (Fig. 4H). In contrast to the lifetime of MG, the time constants for MGT and MGT-CuPc at 750 nm indicate a much longer lifetime. The surface trap states generally increase the lifetime of electrons in semiconductors. Thus, TDR results provided direct evidence for CT from MGT to CuPc, resulting in much enhanced SERS activity using MGT.

Something the ads don’t mention, however, is that both of those products contain lead acetate, a lead compound which the CDC lists as a possible carcinogen. The ingredient can be harmful, especially to children.
