Passive Cooling of a Micromechanical Oscillator with a Resonant Electric Circuit
, 2007 We cool the fundamental mode of a miniature cantilever by capacitively coupling it to a driven rf resonant circuit. Cooling results from the rf capacitive force, which is phase shifted relative to the cantilever motion.

Advanced Functional Materials, EarlyView.The highly anisotropic Fermi surface of bismuth results in variations in magnetotransport properties across different crystallographic directions, which can be characterized by studying microcrystals. To avoid the observed surface melting under room temperature Focused Ion Beam (FIB) irradiation, two low‐temperature FIB fabrication methods are proposed

Precursor Mineral Phases of Forming Mollusk Shell Nacre: A Study of Hydrated Samples
Advanced Functional Materials, EarlyView.Mineral, organic phase, and water are the essential components in mollusk shell nacre formation. Their interplay is not well understood, because the hydrated material is difficult to observe at high resolution, under close to native conditions. Forming nacre is studied using environmental and cryo‐electron microscopy and hydrated ACC phases, together ...

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics
Advanced Functional Materials, EarlyView.Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.
