Radio Frequency (RF) Thawing Irregular Shape Frozen Beef — A Computational Study
Imported beef often comes in halves or quarters of frozen bodies, which are irregular. Radio frequency (RF) heating can reduce processing time and minimize nutritional damage when applied in meat thawing. Because of its large penetration depth and high heating rate, RF thawing has a ... En savoir plus
Shell-Isolated Nanoparticle-Enhanced Raman Spectroscopy: Insight from Simulations with COMSOL Multiphysics® Software
Surface-enhanced Raman spectroscopy (SERS) has been developed as a versatile tool for trace-molecule detection and biomolecular analysis by coupled gold or silver nanostructures in the past two decades. However, SERS suffers from a long-term limitation of application for surface analysis ... En savoir plus
Study of the Structure of Photonic Crystal Fiber with High Negative Dispersion Coefficient
The optical fiber communication has been popular topics besides robot study nowadays.
