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

Published 25 February, 2022

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.

Estimating reward & risk with machine learning improves portfolio performance by up to 28%

Published 23 February, 2022

In a study published in KeAi’s The Journal of Finance and Data Science, Michael Pinelis and David Ruppert of US’ Cornell University used macroeconomic data to forecast the monthly prevailing volatility in the US stock market, in addition to the expected return. Previous studies have focused on just the monthly expected return, or predicted both components with simple linear models.

GaN-based CMOS circuits make power integrated systems more efficient

Published 16 February, 2022

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 in situ coring and testing system for deep mining makes “living” samples a reality

Published 14 February, 2022

New in situ coring and testing system will fill in the gaps in the principles, technology and equipment of deep in situ rock mechanics and enable further development of deep-earth, deep-sea, and deep-space prospecting and coring technology.

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

Published 10 February, 2022

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.

Risk appetite of banks for small merchant renewable energy plants remains low

Published 04 February, 2022

With more commercial banks pursuing bold sustainability targets in support of the Paris Agreement, there was an expectation that these plants would now find it easier to secure bank financing. However, a study published in the KeAi journal Global Transitions, suggests this is far from true.

Revolutionary approach for drug-resistant TB has important implications for other diseases

Published 31 January, 2022

In a pioneering study, published in the KeAi journal Synthetic and Systems Biotechnology, scientists used a revolutionary approach in computer-aided drug discovery to explore binding sites between resistance-causing mutations of EMB, and a transmembrane kinase.

7-step blueprint proposes new genetic and food security guidelines for aquaculture

Published 28 January, 2022

Researchers from the Institute of Hydrobiology (IHB) at the Chinese Academy of Sciences, set out to reexamine fish biology and biotechnologies in the wake of these ongoing changes. Based on their findings, they have developed a new nine-step blueprint for improving the use of genetics and new breed creation in aquaculture species. In their paper, they also share their analysis of the potential of these new breeding strategies to improve the aquaculture seed industry and strengthen food security.
