Porous nanosheets have attracted significant attention as viable options for energy storage materials because of their exceptionally large specific surface areas. A recent study (, 2024, , 33-39) has demonstrated that Li/Na-metalized inorganic BP-biphenylene (b-BP) and graphenylene (g-BP) analogues possess suitable functionalities for hydrogen (H) storage. Herein, we evaluate the H storage performance of alkaline earth metal (AEM = Be, Mg, Ca)-decorated b-BP and g-BP structures based on first-principles density functional theory (DFT) calculations.

However, their structural stability and optical nonlinearity potential in bulk form have not been reported. Here, structural, electronic and optical properties of ZnTeO composites have been thoroughly studied using genetic algorithm and density functional theory (DFT).

Based on our previous work, herein, the study specimens AlInN, AlInN, AlInN, AlInN, AlInN, and AlInN have been predicted to be stable phases. These novel phases intrinsically exhibit moderate positive Seebeck curves (199.

Ground state configurations of small hafnium clusters are first derived using Basin-Hopping and Genetic Algorithm in the parallel tempering mode, employing the COMB potential in the energy calculator. These assumed ground state structures are verified by using the Low Lying Structures (LLS) method.
