Medical experts call for a rethink on using minimally invasive surgery in cervical cancer

For many years, surgeons chose minimally invasive surgery (MIS) over open surgery when treating cervical cancer, due to factors such as lower blood loss, fewer complications and shorter recovery times. However, that changed in 2018, when results from the Laparoscopic Approach to Cervical Cancer (LACC) trial were released. It found that patients who underwent an abdominal radical hysterectomy had higher progression-free survival rates than those who underwent a minimally invasive radical hysterectomy.

GaN-based CMOS circuits make power integrated systems more efficient

Complementary logic integrated circuits, also known as CMOS IC, are some of the highest performing logic circuits and offer a promising pathway to meeting those goals. A series of high-performance, GaN-based CMOS logic circuits, which all display the desired “CMOS-like” characteristics have been developed. In this paper, the authors describe how these circuits could have the potential to cut the power consumption of the logic control unit in conversion power systems by 20-30%.

New LiMn2O4 electrode could pave the way for electrochemical recovery of lithium from brine

Lithium has been dubbed the ‘energy metal of the 21st century’. Most of the world's lithium is now extracted from oil well brines, salt-lake brines and geothermal waters. However, increasing the efficiency of the brine lithium recovery process remains a key goal for researchers working in the field. This study describes a new approach using a specially-designed version of a LiMn2O4 electrode, which has the potential to address this issue.

New treatment removes radioactive barium from nuclear wastewater “rapidly and effectively”

Scientists have focused on treating radioactive ions using an adsorption process, which causes the dangerous ions to stick to the adsorbent’s surface, which can then be safely scraped off. However, for this process to work safely and efficiently, achieving the right balance between adsorption capacity and adsorption speed is pivotal; something the various adsorbents that are currently used struggle to achieve. The authors of this paper have developed a new adsorbent that uses a sulfonic acid (–SO3H) group.
