• The gold standard: Biodesign Institute researchers use nanoparticles to make 3-D DNA nanotubes

  Arizona State University researchers Hao Yan and Yan Liu imagine and assemble intricate structures on a scale almost unfathomably small. Their medium is the double-helical DNA molecule, a versatile building material offering near limitless construction potential. In "Science", Yan and Liu, researc more

• Na+ conductivity of the Na+-driven flagellar motor complex composed of unplugged wild-type or mutant PomB with PomA

  PomA and PomB form the stator complex, which functions as a Na+ channel, in the Na+-driven flagellar motor of Vibrio alginolyticus. The plug region of PomB is thought to regulate the Na+ flow and to suppress massive ion influx through the stator channel. In this study, in order to measure the Na+ c more

• INFLUENCE OF THE SECOND EMULSIFICATION STEP DURING PRODUCTION OF W/O/W MULTIPLE EMULSIONS: COMPARISON OF DIFFERENT METHODS TO DETERMINE ENCAPSULATION EFFICIENCY IN W/O/W EMULSIONS

  Abstract As water encapsulation is crucial for most W/O/W emulsion applications, we compare different measurement techniques for its analysis. Therefore, we produce two different W/O/W emulsions that should have different EE, as we change the applied shear rate during the second emulsification more

• Simultaneous determination of diclofenac and its common counter‐ions in less than 1 minute using capillary electrophoresis with contactless conductivity detection

  This paper presents a method for fast and simultaneous determination of diclofenac (DCF) and its common counter‐ions (potassium, sodium, and diethylammonium) using capillary electrophoresis with capacitively coupled contactless conductivity detection (CE‐C4D). On the basis of a single electrophero more
