  • Electronics and magnetic phase transitions typically do not involve mechanical degrees of freedom directly, but their impact on thermodynamic properties affects the mechanical response of a material. Here the authors show that resonators made from 2D materials exhibit anomalies at phase transitions.

  • The electro-optical response of suspended graphene membranes measured by change in wavelength-dependent reflectance can enable interferometric modulation display (IMOD) technology. Here, the authors report suspended double layer graphene based IMOD drums with 2500 pixels per inch.

  • Nonlinear dissipation is frequently observed in nanomechanical resonators, but its microscopic origin remains unclear. Here, nonlinear damping is found to be enhanced in graphene nanodrums close to internal resonance conditions, providing insights on the mechanisms at the basis of this phenomenon.

  • A micrometre-scale device that exploits the piezoresistive characteristics of silicon acts like an engine, converting heat into mechanical work in one mode of operation, and, in another, like a refrigerator, suppressing mechanical fluctuations.

  • Magnetic phase transitions typically lead to changes in a materials magnetostrictive properties. Here, Šiškins et al use the motion of a nanodrum to study the nonlinear magneto-mechanical response of FePS3, and observe changes in the nonlinear stiffness and damping near the Neel temperature.

  • Van der Waals antiferromagnets offer a unique platform for studying magnetism in reduced dimensions, however, the low dimensionality, combined with lack of net magnetization, renders investigation challenging with conventional experimental probes. Here, Houmes et al show how van der Waals antiferromagnets can be investigated via the resonances of a vibrating rectangular membranes of this material.

  • To ensure a sustainable future and combat food scarcity, we must boost agricultural productivity, improve climate resilience and optimize resource usage. There is untapped potential for dense wireless sensor networks in agriculture that can increase yields and support resilient production when linked to smart decision and control systems.

  • In the design optimization of resonance frequencies and Q-factor of nanomechanical resonators, the influence of geometric design on the nonlinear dynamics has been rarely investigated. Here, the authors tune the stress field via soft-clamping, simultaneously increasing both the Q-factor and the onset of nonlinearity of a Si3N4 string resonator.
