A low‐temperature synthesis method of single‐crystalline NCA was successfully achieved by Sn doping, employing the same synthetic conditions as its polycrystalline counterparts. This synthesis was conducted at a temperature that was 150 °C lower than that required for synthesizing single‐crystalline NCA without Sn doping.

Closing the Loop: High‐Precision 3D Photofabrication in Living Tissues
Writing 3D microstructures inside living tissue demands more than laser access; It demands information. Hierarchical sensing captures thermal and mechanical states across pulse‐train, voxel, and structure timescales, feeding a controller that steers the laser in real time.

Absorption of Low-Frequency Sound Energy by Vegetation: A Laboratory Investigation [PDF]
Abstract : Many field research projects have been conducted to study the effects of natural foliage on the propagation and attenuation of sound. This research takes natural foliage into a controlled laboratory setting to test its low-frequency acoustic characteristics. Absorption of low-frequency components of unwanted noise is of interest to the Army,

Mode‐Resolved Phonon Dynamics Under Chemical Pressure in SnTe Thermoelectrics
Chemical pressure reshapes low‐energy optical phonons in SnTe, altering their dispersion and scattering with heat‐carrying acoustic modes. Positive and negative pressure states modify phonon frequencies and lifetimes in distinct ways, revealing how mode‐selective lattice perturbations regulate acoustic–optical interactions and suppress lattice thermal ...

Targeted Mechanogenetics to Modulate Specific Deep Neural Circuits
This study introduces mechanogenetics, a nanobubble‐enhanced sonogenetic strategy for selective modulation of feeding‐related neural circuits in the mouse lateral hypothalamus. Mechanogenetic stimulation modulates feeding behavior through glutamatergic projections from the lateral hypothalamus to the ventral tegmental area, highlighting its potential ...
