Amphoteric Cu‐Doping Leading to High Thermoelectric Performance in p‐Type Bismuth Antimony Telluride
Advanced Functional Materials, EarlyView.This study shows that Cu plays two opposite roles in p‐type Bi0.5Sb1.5Te3 depending on the processing route. Under thermodynamic‐equilibrium bulk‐synthesis, Cu mainly occupies cation sites, increases hole concentration, preserves mobility, and slightly reduces lattice heat transport. The best‐performing composition among the investigated series reaches

Modulated-bath ac calorimetry using modified commercial Peltier elements [PDF]
Review of Scientific Instruments, 2005 We developed a type of ac microcalorimeter based on a modulated-bath technique for measuring the specific heat of small microgram samples in the temperature range from 30 to 300 K, and tested it in magnetic fields up to 14 T. The device is built from a modified commercial Peltier element.

Advanced Healthcare Materials, EarlyView.This study demonstrates that Tf‐PDA NPs combine a receptor‐mediated targeting with mild photothermal activation to enhance nanoparticle accumulation in the brain. NIR‐activated Tf‐PDA NPs increase BBB permeability to NPs in vitro and in vivo without inducing cytotoxicity or adverse immune responses.

Range Extension of a Bimorph Varifocal Micromirror Through Actuation by a Peltier Element [PDF]
IEEE Journal of Selected Topics in Quantum Electronics, 2015 A bimorph varifocal micromirror actuated thermoelectrically by a Peltier element is reported. The single crystal silicon micromirror is 1.2 mm in diameter with a centered 1 mm diameter gold coating for broadband reflection. The actuation principle is capable of varying the micromirror temperature above and below the ambient temperature, which ...
