In the SANA programme unknown emission sources are inspected and emission rates of different gas releases are validated using FTIR-spectroscopy. Gaseous emission rates from industrial and agricultural areas, highways, garbage deposits, open-cast lignite minings, compost heaps and an ensemble of small-...
The analytical method was validated for liquid and gel ABHSs, covering the specificity, linearity and range, accuracy, and precisions, including the limit of detection and the limit of quantitation. The specificity of each target analyte was established using the optimised chromatographic separation ...
Despite decades of work by structural biologists, there are still ~5200 protein families with unknown structure outside the range of comparative modeling. We show that Rosetta structure prediction guided by residue-residue contacts infer... S Ovchinnikov,H Park,N Varghese,... - 《Science》 被引...
matrix dependency, sensitivity, effort for sample preparation, instrumentation, cost, duration, and sample size (picogram to kilogram). For example, the Kjeldahl method is a reference method for protein quantification in food, but it is time consuming and needs large protein amounts (typically...

SAD or MAD involves the use of synchrotron radiation to excite the crystal at a single or multiple specific wavelengths. Most commonly, all methionine residues are replaced by selenomethionines in the protein. Selenomethionine contains a selenium instead of a sulfur atom, which makes it a moderately...
Earth's core–mantle boundary (CMB) is located at approximately 2900 km beneath the surface, corresponding to pressures (P) of 136 GPa and temperatures (T) greater than 2500 K. SiO2 is a common mineral in the Earth's crust, and silicates comprise most of the mantle. Free SiO2 may also...
Samples from a suite of shale reservoir rocks were analysed using standard Quantitative X-Ray Diffraction (QXRD) and with FTIR. Unknown mineral concentrations in the samples were then predicted using spectra and the calibration equations. Good correlations were achieved between the QXRD and ATR-CLS...
Carbon in quenched glasses was measured and characterized using Fourier transform infrared spectroscopy (FTIR) and Raman Spectroscopy and was found to be dissolved as carbonate (CO). The FTIR spectra showed COdoublets that shifted systematically with the MgO and CaO content of silicate melts. Using ...
