Group velocity of the probe light in semiconductor–metal molecules
, 2012 The group velocity of light is investigated in a hybrid nanostructure comprised of semiconductor quantum dot (SQD) and metal nanoparticle (MNP). In the presence of MNP, the hybrid absorption of the system can be eliminated and forms a broad transparency ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Superluminal velocity through near-maximal neutrino oscillations or by being off shell
, 2012 Recently it was suggested that the observation of superluminal neutrinos by the OPERA collaboration may be due to group velocity effects resulting from close-to-maximal oscillation between neutrino mass eigenstates, in analogy to known effects in optics.

Two‐Stage Framework for Precise Measurement of Marsquake Surface Wave Group Velocity Dispersion
Earth and Space ScienceSurface wave dispersion analysis is crucial for investigating crustal and mantle structures on Earth and other celestial bodies. On Mars, Rayleigh and Love waves have been detected, with Rayleigh waves exhibiting vertical and radial motion and Love waves

Group velocity mismatch at ultrashort electromagnetic pulse propagation in nonlinear metamaterials
Open Physics, 2019 The parametric interaction of optical wave pulses in metamaterials is considered in the first approximation of the theory of dispersion. The interaction between the quasi-monochromatic pump wave and the wave pulse at the total frequency with quadratic ...

ULTRASLOW GROUP VELOCITY AND ENHANCED NONLINEAR OPTICAL EFFECTS IN A COHERENTLY DRIVEN HOT ATOMIC GAS [PDF]
, 1999 We report the observation of small group velocities of order 90 m/s and large group delays of greater than 0.26 ms, in an optically dense hot rubidium gas ( $\ensuremath{\approx}360\mathrm{K}$).

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...
