The combination of suprascapular nerve block (SSNB) and axillary nerve block (ANB) has been reported to provide safe and effective analgesia for arthroscopic shoulder surgery. This study was designed to identify anatomic landmarks of the suprascapular nerve (SSN) and axillary nerve (AN) and to evaluate the effects of SSNB and ANB using the identified landmarks.This study included 52 cadaveric shoulders...
The authors demonstrated decoration of Ru nanoparticles on the surface of double-walled CNTs (DWCNTs) using a chemical process and studied their field emission properties. Ru is more stable than the low work function alkali metals when exposed to oxygen. Moreover, the melting point of Ru is much higher than that of RuO2.
The field emission properties of double-walled carbon nanotubes (DWCNTs) were remarkably improved by decorating their surface with ruthenium (Ru) metal nanoparticles. The Ru nanoparticles were attached effectively on the surface of DWCNTs via a chemical procedure. The Ru-decorated DWCNTs showed lower turn-on voltage, higher emission current density, and improved emission uniformity compared with pristine...
