Inter-population variation and phenotypic plasticity in kairomone use by a poly-specialist spider-eating predator

Ana, M. Cerveira; Robert, R. Jackson (springer link, 2021)

Previous research on Cyrba algerina (Araneae, Salticidae) has shown this jumping spider expresses predatory specialisation with respect to spiders as prey as well as inter-population variation in responsiveness to prey-spider ...

Improving the efficiency and stability of tin-based perovskite solar cells using anilinium hypophosphite additive

Jorim, Okoth Obila; Hongwei, Lei; Elijah, Omolo Ayieta; Alex, Awuor Ogacho; Bernard, O. Aduda; Feng, Wang (Royal Society of Chemistry, 2021)

Tin (Sn) is a potential replacement for lead in organic–inorganic perovskite solar cell (PVSC) technology due to the attractive optoelectronic properties of Sn-perovskites. However, the poor stability of Sn2+ ions is still ...
