    Bottom-Up Enhancement of g-C3N4 Photocatalytic H2 Evolution Utilising Disordering Intermolecular Interactions of Precursor by Xue Lu Wang, Wen Qi Fang, Yu Hang Li, Pengfei Liu, Haimin Zhang, Yun Wang, Porun Liu, Yefeng Yao, Huijun Zhao, Hua Gui Yang

    Published 2014-01-01
    “…The final sample possesses much looser structure and provides a broadening optical window for effective light harvesting and charge separation efficiency, which exhibits significantly improved H2 evolution by photocatalytic water splitting. The bottom-up mechanochemistry method opens new vistas towards the potential applications of weak interactions in the photocatalysis field and may also stimulate novel ideas completely different from traditional ones for the design and optimization of photocatalysts.…”

    A model-independent compact dynamical system formulation for exploring bounce and cyclic cosmological evolutions in $$f\, (R)$$ f ( R ) gravity by Saikat Chakraborty, Charlotte Louw, A. S. Agrawal, Peter K. S. Dunsby

    Published 2024-12-01
    “…The formulation is model-independent in the sense that one needs to specify not a particular functional form of f(R) a-priori, but rather a particular cosmological evolution, which fixes the cosmography. In a sense, our approach is the way around the reconstruction method. …”
