A Homogeneous Capillary Tube Model - Comprehensive Parameter Studies Using Isobutane As Refrigerant
, 2012 In this work a homogenous capillary tube model using R600a (isobutane) as refrigerant is presented. The capillary tube model underlies common restrictions; it is assumed to be adiabatic, straight with constant cross section and operates under steady ...

Neodymium‐Doped Nanocrystals for Sensing Cellular Temperature at the Nanoscale
Advanced Optical Materials, EarlyView.Neodymium‐doped NaYF4 nanocrystals are engineered as bright, biocompatible nanothermometers for intracellular temperature mapping. Their ratiometric near‐infrared emission enables highly sensitive, nanoscale thermal readouts in living cells. Combined with gold nanostars for photothermal therapy, they reveal pronounced subcellular heating heterogeneity ...

Advanced Science, EarlyView.This study identifies palmitoylation as a novel regulatory modification of SMAD4, mediated by ZDHHC22/APT2. It activates fatty acid synthesis, creating a self‐reinforcing SMAD4–FASN–palmitate feedback loop that drives pancreatic cancer growth and enhances radiotherapy sensitivity.
