GPU Computing in XAFS

Journal of Physics: Conference Series, 2013
Modern graphics processing units (GPUs) are powerful parallel computers. Porting the mathematically intense, parallelizable algorithms of XAFS to run on GPUs should expand the scale of tractable XAFS calculations. Part of a time-limiting subroutine in FEFF 8.4 (fms) was converted to run on a GPU, showing significant performance gains.

A High‐Loading Zn Single‐Atom Nanozyme Targets the Zn/HIF‐1α/GLUT1 Axis to Disrupt Glucose Metabolic Reprogramming and Remodel the Tumor Immune Microenvironment

Advanced Science, EarlyView.
A high‐loading Zn single‐atom nanozyme (ZMG@CS) delivers ML‐SA5 and GOx to lysosomes. ML‐SA5 activates TRPML1 to release endogenous Zn2+, while the nanozyme provides exogenous Zn2+ and GOx‐driven acidification amplifies ROS production. Together, these effects suppress the HIF‐1α/GLUT1 axis, disrupt glucose and redox homeostasis, induce disulfidptosis ...
