DOI: 10.1002/jbio.202200164
Abstract: Photoacoustic microscopy has received great attention due to the benefits of the optical resolution contrast as well as its superior spatial resolution and relatively deep depth. Like other imaging modalities, photoacoustic images suffer from noise,… read more here.

DOI: 10.1021/jacs.0c12843
Abstract: We report an asymmetric homocoupling of ortho-(iodo)arylphosphine oxides and ortho-(iodo)arylphosphonates resulting in highly enantioenriched axially chiral bisphosphine oxides and bisphosphonates. These products are readily converted to enantioenriched biaryl bisphosphines without need for chiral auxiliaries or… read more here.

DOI: 10.1063/1.5093789
Abstract: Defocus scanning, which causes a serious deterioration of the transverse resolution out of the focal zone, is a big obstacle to the application of optical-resolution photoacoustic (PA) endoscopy (OR-PAE) in imaging internal hollow organs. However,… read more here.
