Advanced silicon nanostructures derived from natural silicate minerals

Currently, over 80% of global energy consumption comes from the combustion of conventional fossil fuels. However, the overuse of these nonrenewable energy resources has given rise to the accelerated exhaustion of the limited resources, but also causes severe environmental issues or even climate changes [1].With the further growing industrialization and

CO2 storage potential of basaltic rocks in Iceland and the oceanic

Studies on mineral storage of CO 2 in basaltic rocks are still at an early stage. Therefore, natural analogues are important for gaining a better understanding of CO 2 fixation in basaltic rocks. Volcanic geothermal systems serve as an applicable analogue since the systems receive considerable amounts of CO 2 from magma in the roots of the systems. Wiese et al. [1]

Mechanical behavior of rock under uniaxial tension: Insights from

Generally, due to the lower strength of cement compared to mineral grains, rocks tend to undergo intergranular fracture under tensile stress (Ma et al., 2023). In other words, the absolute energy storage capacity of rock determines the severity of the rockburst. Relative energy storage capacity is more like an inherent property of rock.
