Synergistic effects of biochar and plants can reduce greenhouse gas emissions from salt affected soil.

Applying biochar and using cover crops are two potential approaches to reduce greenhouse gas (GHG) emissions. However, the effectiveness of these methods, individually or in combination, in salt-affected soils remains unclear. Thus, the objective was to determine the impact of barley (Hordeum vulgare) and biochar on NO and CO emissions from salt-affected soil.

Purcell enhanced laser action using a super-Tamm cavity mode.

Optical Tamm structures have potential for the development of optoelectronic devices, provided they overcome the challenge of low-quality factor of modes and inherent losses associated with plasmonic metal films. In this work, we present lasing in a super-Tamm structure consisting of a silver thin film deposited on a 4-(dicyanomethylene)-2-methyl-6-(4- dimethylaminostyryl)-H-pyran (DCM) dye-doped polyvinyl alcohol (PVA) spacer layer coated on a SiO/TiO one-dimensional photonic crystal with a lasing threshold of ∼0.07 mJ.

Radiological resolution of community-acquired pneumonia in hospitalised patients in North India.

Background: Community-acquired pneumonia (CAP) is the most common infectious cause of death, and radiology is a corner stone of its management. No data are available from India regarding the radiological resolution of CAP in the current antibiotic era. We set out to study determine the radiological resolution of CAP.

Ultrasonication of microalgal biomass: Acoustics study and enhanced bioelectricity generation in microbial fuel cells.

The present work involved the pretreatment of cultivated microalgal biomass by ultrasonication to improve its suitability as a substrate in microbial fuel cells (MFCs). Ultrasonication efficiently breaks down the cell walls of microalgae, therefore enhancing the accessibility of intracellular organic material by microbes and thussubsequently producing electrons and protons. In the present research work along with the ultrasonic pretreatment of our samples, non-destructive ultrasonic characterization using anultrasonic interferometer has been done, to study the molecular behavior of the microalgae.

Degradation of Polyaromatic Hydrocarbons by Biosurfactant-Producing NG4.

Polyaromatic hydrocarbons (PAHs) are a group of organic pollutants commonly found in the environment due to industrial activities, incomplete burning of fossil fuels, and oil spills. Bioremediation of PAHs has emerged as a promising approach. This study investigated the biodegradation of PAHs (anthracene, naphthalene, phenanthrene, anthraquinone, and anthrone) at 100 ppm to 1000 ppm in the presence of glucose and glycerol by a biosurfactant-producing strain of NG4.
