Spin-state crossovers are phenomena where, under changes in temperature or pressure, the spin-state of an ion changes. In some materials, this spin-state crossover occurs simultaneously with a metal-insulator transition, driven by a valence transition. Control over such valence, spin-state, and metal-insulator transitions has much technological appeal, but, thus far, materials displaying this have been limited to cryogenic temperatures. Here, the authors show that in strained films of (Pr1-yYy)1- xCaxCoO3-δ, these transitions can be promoted to room temperature.

Widespread ecosystem degradation demands scalable strategies for plant establishment — the process of successful seed dispersal and burial that enables a seed to germinate, survive its vulnerable early stages and emerge as a resilient seedling. However, harsh environmental conditions often make conventional seeding efforts costly and ineffective. Inspired by natural seeding mechanisms that exploit environmental cues, emerging biodegradable, stimulus-driven morphing matter-enabled machines can support plant establishment across its critical phases, offering a pathway to low-impact ecological restoration.
