Research describes a rapid computational method for identifying incorrect molecular structures that have been mistakenly determined using misassigned NMR signals. Ariel Sarotti, a scientist in Argentina, has developed a tool that combines calculated and experimental 13C NMR data to flag up ...
A new setup for hybrid photoacoustic and ultrasound imaging with optical ultrasound detection provides perfectly co-registered dual-modality section images
