The analysis studies impact of nanocomposites (NCs) to improve thermal efficiency in hydrogen liquefaction while decreasing energy consumption. The study uses an innovative combination of experimental investigations coupled with machine learning methods to identify superior nanocomposites for their peak performance characteristics. Experimental data measurement of key thermophysical characteristics are estimated by using Pearson's-r correlation analysis. The weightage analysis obtained through the MEREC analysis. The priority weights obtained for the inputs are concentration of nano-additives concentration at 33% while flow rates take 29% and pressure receives 23% and temperature stands at 14%. The optimum input operating characteristics were found in combination 9, with pressure of 0.23 MPa, temperature of 260 K, flow rate of 0.11 kg/s, and NC concentration of 0.24 wt%, leading to the most efficient performance in the hydrogen precooling process. The combination of Graphene/TiO2 (Anatase) with g-C3N4/TiO2 (Graphitic) and SiC/TiO2 (Silicon Carbide) nano-additives delivering optimum energy consumption and coefficient of performance of 2.70 kWh/kgLH2 and 5. Effective heat transfer combined with reduced energy losses from integrating these NCs leads to more sustainable and cost-effective hydrogen liquefaction. New energy infrastructure designs benefits from these findings that support hydrogen as a clean energy vector while enhancing industrial liquefaction procedures.

02:13Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.

The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
02:24Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
