Current-Induced Second-Harmonic Generation in Silicon

Frontiers in Optics, 2006
The contribution to the optical second-harmonic generation resulting from the dynamic influence of the direct electric current flowing along the silicon (100) surface on the electron distribution anisotropy in the surface region is observed.

Localized Temperature Monitoring in Mouse Brain during Light Delivery via a Non‐Planar Tapered Fiber‐Integrated µRTD Sensor

Advanced Materials, EarlyView.
We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...

Response of Glass and Liquid Phases in the Vortex lattice to an external AC magnetic field at different frequencies

, 2004
We individuated a method to distinguish a glass phase from a highly viscous liquid phase in a lattice of vortices, established in type-two superconductors.

An improvement of a single-plane balancing method via residual current of a rotor directly coupled to an induction motor

Nova Scientia, 2016
An efficient method for single-plane rotor balancing which requires some components of the electric signal spectrum from each phase of the electric motor to which it is directly coupled is developed.
