The use of catalysed exchange of deuterium (D) between hydrogen (H) gas and liquid water using the bithermal hydrogen water (BHW) process is a promising and environment-friendly approach for the production of heavy water. However, the use of this approach is limited by the lack of a suitable catalyst that has good activity at high operating pressures required for practical applications. We report the development of hydrophobic platinum-doped carbon aerogel (PtCA) catalyst which shows good catalytic activity for H/D isotope exchange reactions at operating pressures up to 20 bar.Keywords

Functionalism and Neo-functionalism are important theories of international politics. Both these theories have helped us to analyse growing interconnectedness and interdependence that has come to characterize foreign relations between various nations, especially their relations with group of countries located in a specific region. While European Union represents the most important example of successful integration of nations in functional terms, there has not been much development in this respect as far as countries of south Asia are concerned. My research proposal seek to identify main cause this this tendency as well as examine the possibility of future cooperation between various nations located in south Asia that may ultimately result into development of larger functional organizations.Keywords
Functionalism, SAARC, Neo-Factionalism, Bick Corridor, European Union.Full Text

A study was undertaken in the Vaishali district of Bihar, India, in 2020 to assess the effect of various agroforestry systems (AFS) on the distribution of different pools of soil organic carbon (fraction I – very labile, fraction II – labile, fraction III – less labile and fraction IV – non-labile), carbon stocking and soil microbial activity. The mean (0–45 cm) total organic carbon (TOC) in different AFS ranged from 5.55 to 6.64 Mg C ha–1, with the highest under poplar-based AFS (PB-AFS). Across the AFS studied, the C stocks (0–45 cm) varied from 36.24 (mango-based AFS) to 41.43 Mg C ha–1 (PB-AFS). Overall, the magnitude of C fractions showed the order: fraction I > fraction IV > fraction III > fraction II. Significantly higher soil microbial biomass carbon was recorded under PB-AFS (219.36 mg g–1) in 0–15 cm depth. Basal respiration was also the highest under PB-AFS (0.54 mg CO2-C g–1 h–1), followed by TB-AFS (0.50 mg CO2-C g–1 h–1) in 0–15 cm depth. Principal component analysis result showed that PC 1 and PC 2 represented about 97% of the total variation. TOC and active carbon pool had the maximum loading in PC 1, while microbial metabolic quotient and bulk density had the maximum value in PC 2Keywords
