Development of 3-dimensional CoO catalysts with various morphologies for activation of Oxone to degrade 5-sulfosalicylic acid in water.

Since 5-sulfosalicylic acid (SFA) has been increasingly released to the environment, SO-based oxidation processes using Oxone have been considered as useful methods to eliminate SFA. As CoO has been a promising material for OX activation, the four 3D CoO catalysts with distinct morphologies, including CoO-C (with cubes), CoO-P (with plates), CoO-N (with needles) and CoO-F (with floral structures), are fabricated for activating OX to degrade SFA. In particular, CoO-F not only exhibits the highest surface area but also possesses the abundant Co and more reactive surface, making CoO-F the most advantageous 3D CoO catalyst for OX activation to degrade SFA.

Prussian Blue Analogue-derived co/fe bimetallic nanoparticles immobilized on S/N-doped carbon sheet as a magnetic heterogeneous catalyst for activating peroxymonosulfate in water.

While Co is the most effective metal for activating PMS, extensive efforts are made to develop Co/Fe species (CF) (e.g., CoFeO) for imparting magnetic properties and facilitating recovery of catalysts.

LabPush: a pilot study of providing remote clinics with laboratory results via short message service (SMS) in Swaziland, Africa - a qualitative study.

Background: Developing countries are confronting a steady growth in the prevalence of the infectious diseases. Mobile technologies are widely available and can play an important role in health care at the regional, community, and individual levels. Although labs usually able to accomplish the requested blood test and produce the results within two days after receiving the samples, but the time for the results to be delivered back to clinics is quite variable depending on how often the motorbike transport makes trips between the clinic and the lab.
