Insights on Strain-Substrate Interactions and Antioxidant and Anti-Bacterial Properties of the Velvet Foot Medicinal Mushroom Flammulina velutipes (Agaricomycetes).

To study the best substrate for the Indian subcontinent, four different substrates (sawdust + wheat bran, wheat straw + wheat bran + corn cobs, sawdust + corn cobs and wheat straw + wheat bran) were screened for six different Flammulina velutipes strains.

In study it was found that the strain DMRX-767 and DMRX-768 were the most promising for yield and biological efficiency in all substrates and wheat straw + wheat bran being the best with respect to BE.

Gigahertz semiconductor laser at a center wavelength of 2 µm in single and dual-comb operation.

Dual-comb lasers are a new class of ultrafast lasers that enable fast, accurate and sensitive measurements without any mechanical delay lines. Here, we demonstrate a 2-µm laser called MIXSEL (Modelocked Integrated eXternal-cavity Surface Emitting Laser), based on an optically pumped passively modelocked semiconductor thin disk laser. Using III-V semiconductor molecular beam epitaxy, we achieve a center wavelength in the shortwave infrared (SWIR) range by integrating InGaSb quantum well gain and saturable absorber layers onto a highly reflective mirror.

Watt-level and sub-100-fs self-starting mode-locked 2.4-µm Cr:ZnS oscillator enabled by GaSb-SESAMs.

Femtosecond lasers with high peak power at wavelengths above 2 µm are of high interest for generating mid-infrared (mid-IR) broadband coherent light for spectroscopic applications. Cr-doped ZnS/ZnSe solid-state lasers are uniquely suited since they provide an ultra-broad bandwidth in combination with watt-level average power. To date, the semiconductor saturable absorber mirror (SESAM) mode-locked Cr:ZnS(e) lasers have been severely limited in power due to the lack of suitable 2.

Modelling of the methyl halide biodegradation in bacteria and its effect on environmental systems.

Methyl halide group of pesticides are being used widely in past decades as fumigant but due to their hazardous effect, these pesticides are not sold directly. They are volatile and gaseous in nature and may easily come in the contact of trophosphere and stratosphere. In troposphere, they are harmful to the living beings; nevertheless, in stratosphere they react with ozone and degrade the ozone layers.
