Millikelvin Intracellular Nanothermometry with Nanodiamonds
Nanothermometry in living cells is crucial for understanding heat diffusion and advancing cellular biology and drug discovery. Previous studies have reported controversial intracellular temperature variations. Using nanodiamond nanothermometry in macrophages, it is found that, in such experimental setting, apparent temperature changes are actually due ...

Standalone Integrated Magnonic Devices
A standalone (not requiring external bias magnetic field) and tunable magnonic device is reported with all‐electric input and output, fully integrated on silicon (total footprint of 100 × 150 µm) and 3–8 GHz frequency band. This is achieved by monolithic integration of a CoFeB conduit with RF antennas and an assembly of NiFe and SmCo micromagnets ...

Coherent Interaction of Light and Single Molecules in a Dielectric Nanoguide [PDF]
We present a new scheme for performing optical spectroscopy on single molecules. A glass capillary with a diameter of 600 nm filled with an organic crystal tightly guides the excitation light and provides a maximum spontaneous emission coupling factor ($\

Polarization‐Controlled Strong Light–Matter Interaction With Templated Molecular Aggregates
Graphene nanoribbons act as a template for brick‐shaped organic semiconductor molecules. The templating results in optoelectronic properties resembling those of a single crystal. The templated layer supports optical transitions with well‐oriented transition dipole moments.

Reinforcement Learning-Based Adaptive Control of a Piezo-Driven Nanopositioning System
This article proposes a new reinforcement learning (RL)-based adaptive control design for precision motion control of a two-degree-of-freedom piezoelectric XY nanopositioning system. In this design, an actor-critic structure is developed to eliminate the

A Rotating-Tip-Based Mechanical Nano-Manufacturing Process: Nanomilling [PDF]
We present a rotating-tip-based mechanical nanomanufacturing technique, referred to here as nanomilling. An atomic force microscopy (AFM) probe tip that is rotated at high speeds by out-of-phase motions of the axes of a three-axis piezoelectric actuator ...

Kinesin‐Driven De‐Mixing of Cytoskeleton Composites Drives Emergent Mechanical Properties
Optical tweezers microrheology and fluorescence microscopy is coupled with simulations and mathematical modeling to discover that active cytoskeleton composites exhibit a rich ensemble of emergent mechanical response characteristics, from yielding to stiffening, governed by kinesin‐driven restructuring from well‐mixed interpenetrating double‐networks ...
