Advanced Functional Materials, EarlyView.This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Label-free detection of anticancer drug paclitaxel in living cells by confocal Raman microscopy [PDF]
, 2013 Confocal Raman microscopy, a non-invasive, label-free, and high spatial resolution imaging technique is employed to trace the anticancer drug paclitaxel in living Michigan Cancer Foundation-7 (MCF-7) cells. The Raman images were treated by K-mean cluster

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions
Advanced Functional Materials, EarlyView.DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Thermal effects on electron-phonon interaction in silicon nanostructures
, 2009 Raman spectra from silicon nanostructures, recorded using excitation laser power density of 1.0 kW/cm^2, is employed here to reveal the dominance of thermal effects at temperatures higher than the room temperature.

Advanced Functional Materials, EarlyView.This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

Macedonian Journal of Chemistry and Chemical Engineering, 2008 Infrared and Raman vibrational spectra of magnesium disaccharinate heptahydrate, Mg(sac)2⋅7H2O, in the 4000–380 cm–1 region (for infrared) and 4000–100 cm–1 region (for Raman) were studied. The assignment of the spectra was based on the experimental data

Raman Spectrum of Fluorobenzene [PDF]
Nature, 1933 BRADLEY1 has studied the Raman spectra of CHFCl2 and CF2Cl2, which appear to be the only fluorine compounds so far investigated. I have recently studied mono-fluorobenzene, and its Raman frequencies are found to be (in cm.-1):

Raman Spectrum of Deuterobenzene [PDF]
Nature, 1935 WE have photographed the Raman spectra of the various deuterobenzenes. In order to obtain the isotopic shifts of the Raman frequencies with a fair accuracy, the spectra were investigated with high dispersion, which necessitates a rather large volume of the substance; the Raman tube employed contained 18 c.c.

Raman scattering in a Heisenberg {\boldmath $S=1/2$} antiferromagnet on the triangular lattice
, 2008 We investigate two-magnon Raman scattering from the $S=1/2$ Heisenberg antiferromagnet on the triangular lattice, considering both the effect of renormalization of the one-magnon spectrum by 1/S corrections and final-state magnon-magnon interactions. The
