ten Bosch, Gijs (author), Tian, J. (author), Umasankar, G. (author), Voncken, Christel (author), Zwienink, Leonie (author)Currently, the Southwestern Delta is ill. The inability to produce its essential ecosystem services hinders the Delta from being healthy. Systems that make the Delta economy prosper are the main reasons for this obstruction. If current hazards like salinisation, soil depletion, and nitrogen pollution continue; the livelihood of the peri-urban...student report 2024

Tian, He (author)Organic micropollutants (OMPs) originate from organic chemicals such as drugs and pesticides that are widely used in human activities. OMPs are difficult to remove by conventional water treatment techniques, and hence continue to accumulate in natural water bodies. More effective methods need to be investigated for the removal of OMPs in...master thesis 2024

(author)Nickel-rich layered oxide cathodes promise ultrahigh energy density but is plagued by the mechanical failure of the secondary particle upon (de)lithiation. Existing approaches for alleviating the structural degradation could retard pulverization, yet fail to tune the stress distribution and root out the formation of cracks. Herein, we report...journal article 2024
