Synthetic fuels and chemicals from CO2: Ten experiments in parallel      (via sciencedaily.com)     Original source 

Why do just one experiment at a time when you can do ten? Researchers have developed an automated system, which allows them to research catalysts, electrodes, and reaction conditions for CO2 electrolysis up to ten times faster. The system is complemented by an open-source software for data analysis.

First specific PET scan for TB could enable more effective treatment      (via sciencedaily.com)     Original source 

A more accurate way to scan for tuberculosis (TB) has been developed, using positron emission tomography (PET). The team has developed a new radiotracer, which is taken up by live TB bacteria in the body. Radiotracers are radioactive compounds which give off radiation that can be detected by scanners and turned into a 3D image. The new radiotracer, called FDT, enables PET scans to be used for the first time to accurately pinpoint when and where the disease is still active in a patient's lungs.

Aromatic compounds: A ring made up solely of metal atoms      (via sciencedaily.com)     Original source 

The term aromaticity is a basic, long-standing concept in chemistry that is well established for ring-shaped carbon compounds. Aromatic rings consisting solely of metal atoms were, however, heretofore unknown. A research team recently succeeded in isolating such a metal ring and describing it in full.

Microrobot-packed pill shows promise for treating inflammatory bowel disease in mice      (via sciencedaily.com)     Original source 

Engineers have developed a pill that releases microscopic robots, or microrobots, into the colon to treat inflammatory bowel disease (IBD). The experimental treatment, given orally, has shown success in mice. It significantly reduced IBD symptoms and promoted the healing of damaged colon tissue without causing toxic side effects.

An optical lens that senses gas      (via sciencedaily.com)     Original source 

A research team has developed a small optical lens, only a few millimeters in size, whose refractive behavior changes in the presence of gas. This 'intelligent' behavior of the micro-lens is enabled by the hybrid glass material from which it is made. The molecular structure of the lens consists of a three-dimensional lattice with cavities that can accommodate gas molecules, thereby affecting the optical properties of the material.

Towards non-toxic antifouling agents: A novel method for total synthesis of scabrolide F      (via sciencedaily.com)     Original source 

Norcembranolide diterpenes, isolated from the soft corals of the genus Sinularia, are important compounds for the development of new drugs, owing to their diverse biological activities. However, total synthesis methods for these compounds are scarce. Now, a team of researchers has achieved the total synthesis of scabrolide F, a norcembranolide diterpene. They also revealed its non-toxic antifouling properties. This novel method can lead to the development of new drugs and antifouling agents.
