    Open carbon frameworks - a search for optimal geometry for hydrogen storage by Kuchta, Bogdan

    Published 2013
    “…From an analysis of an analytical model and simulations of adsorption the physical limits of hydrogen adsorption have been defined: (i) higher storage capacities in slit-shaped pores can be obtained by fragmentation/truncation of graphene sheets into nano-metric elements which creates surface areas in excess of 2600 m2/g, the surface area for infinite graphene sheets; (ii) the positive influence of increasing surface area is compensated by the decreasing energy of adsorption in the carbon scaffolds of nano-metric sizes; (iii) for open carbon frameworks (OCF) built from coronene and benzene molecules with surface areas 6500 m2 g-1, we find an impressive excess adsorption of 75–110 g H2/kg C at 77 K, and high storage capacity of 110–150 g H2/kg C at 77 K and 100 bar; (iv) the new OCF, if synthesized and optimized, could lead to required hydrogen storage capacity for mobile applications.…”

    Global fertility in 204 countries and territories, 1950–2021, with forecasts to 2100: a comprehensive demographic analysis for the Global Burden of Disease Study 2021 by Natalia V, Bhattacharjee

    Published 2024
    “…The share of livebirths was projected to decline between 2021 and 2100 in most of the six other super-regions—decreasing, for example, in south Asia from 24·8% (23·7–25·8) in 2021 to 16·7% (14·3–19·1) in 2050 and 7·1% (4·4–10·1) in 2100—but was forecast to increase modestly in the north Africa and Middle East and high-income super-regions. …”

    Nanospace-engineered carbons for reversible storage of natural gas and hydrogen by Romanos, J.

    Published 2011
    “…Langmuir and Ono-Kondo analysis of CH4 excess isotherms at 295 K gives surface area (2400-2700 m2/g, agree with BET area), film thickness (~0.4 nm), saturated film density (320-440 g/cm3), and average binding energy (8-9 kJ/mol). 6.Briquetting can increase volumetric storage capacity by factor of 2 if surface area remains constant.…”
