Rounded Monodisperse Fluorescent Nanodiamonds
Small, EarlyView.Nanodiamond (ND) shape control using rapid molten‐nitrate etching is studied as a scale‐up method for monodispersed rounded particles. Optimal etching condition (567°C for 6 min) yields NDs with atomically stepped surfaces and reduced sp2 content. Compared to angular control, rounded NDs exhibit an increased proportion of luminescent particles (66% vs.

Small, EarlyView.A slightly buckled 2D kagome metal‐organic framework (MOF) adsorbed on Ag(111) hosts localized spins which are Kondo‐screened by the underlying metal substrate. Using the tip of a scanning tunneling microscope, the MOF can be vertically manipulated to controllably change its adsorption height and with it, the Kondo coupling strength.

Bias Polarity Switching (BiPS): A Transient Method for Probing Interfacial Carrier Dynamics
Small Methods, EarlyView.Bias Polarity Switching combines optical excitation with rapid bias reversal to probe near‐interface carrier accumulation, trapping, detrapping, and extraction together with bulk carrier transport. The method provides access to defect kinetics and contact‐related transport processes, offering a complementary approach for investigating semiconductor ...

Journal of Animal Ecology, EarlyView.Our paper investigates the crucial role of African forest elephants (Loxodonta cyclotis) on the functioning of rainforest ecosystems, through the lens of bird communities. It reveals that the critically endangered megaherbivores are inextricably linked to survival of another key group imperilled by land‐use change: understory invertivore birds ...
