A simple, rapid and environmentally friendly method was developed for micro-Raman spectroscopy determination of pesticide residues on the surface of fruits. Raman spectra of fruits, pesticides and pericarps sprayed by pesticide solutions were acquired using a laser power of 14 mW at excitation wavelength of 780 nm. From the Raman spectra, the residual pesticides could be distinguished and deter...

The interactions of gravitons with matter are calculated in parallel with the familiar photon case. It is shown that graviton scattering amplitudes can be factorized into a product of familiar electromagnetic forms, and cross sections for various reactions are straightforwardly evaluated using helicity methods.
The new compound Cs10P8Se20 features the heterotetracyclic [P3Se7] 3anion, a phosphorus-rich four-membered-ring species that possesses a P-P-P unit and formally P3þ and P4þ centers. It crystallizes in the orthorhombic space group Pnnm with a = 26.5456(7) Å, b = 8.0254(2) Å, c = 11.9031(4) Å, and Z = 2 at 100(2) K. The cyclic anion is cocrystallized with a [P2Se6] 4anion. Electronic absorption, ...
It is shown that in the Glauber scattering of a fast quark in the external field loop corrections to the gluon emission amplitude due to virtual softer gluon after renormalization coincide with a correction due to reggeization of the exchanged gluon in the BFKL picture.
To better understand and quantify aerosol radiative forcing and reduce the uncertainty of its climate effect, it is of vital importance to realize the aerosol components classification and quantification. For this purpose, we developed a powerful lidar system employed a multi-channels spectrometer, with capabilities of providing high spatial and temporal resolution measurements of Raman scatter...
