Correlation of Superlattice Cross-Plane Thermal Conductivity with Emission Wavelength in InAlAs/InGaAs Quantum Cascade Lasers

open access: yesMicromachines, 2022
The low cross-plane thermal conductivity of quantum cascade lasers (QCLs) is a significant limitation in their Continuous-Wave (CW) performance. Structural parameters such as individual layer thicknesses and interface density vary for QCLs with different

Assessing the rigidity of thermoplastic masks for head immobilization effectiveness in stereotactic radiosurgery

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract This study compared three Brainlab thermoplastic masks—Cranial 4pi basic, stereotactic (Close Mask V2), and open‐face—to see how well they limited head movement during Stereotactic Radiosurgery (SRS). Using a head phantom, we tested rotational movements (pitch, yaw, and roll) and measured displacements with the ExacTrac system.

Regulating Protein Immobilization During Cell‐Free Protein Synthesis in Hyaluronan Microgels

open access: yesAdvanced Biology, EarlyView.
Bifunctional microgels carrying a linear DNA template and Ni2+‐activated NTA moieties are used as platform for cell‐free protein synthesis and in situ protein immobilization. By varying the concentration of NTA moieties in the microgels, the amount of GFP‐His immobilized inside the microgel and released to the microgel environment can be regulated ...
