INTRODUCTION: A clear and well-documented gender bias exists in the evaluation of sexual outcomes for women undergoing urologic surgery. Due to the anatomic template of anterior exenteration, women are commonly left with side effects that include sexual dysfunction and...

Noble-Metal Nanorod Cryoaerogels with Electrocatalytically Active Surface Sites.

ACS applied materials & interfaces

Zámbó D, Rusch P, Lübkemann F, Bigall NC.
