Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

FEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Underlying Neural Mechanisms of Cognitive Improvement in Fronto-striatal Response Inhibition in People Living with HIV Switching Off Efavirenz: A Randomized Controlled BOLD fMRI Trial

Infectious Diseases and Therapy
Introduction It is unclear whether neurotoxicity due to the antiretroviral drug efavirenz (EFV) results in neurocognitive impairment in people living with HIV (PLWH).

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Efficient State Estimation in Power Networks for Reactive Power Losses Compensation [PDF]

, 2013
We consider the problem of optimal reactive power compensation for the minimization of power distribution losses in a smart microgrid with raw measurements. We provide two distributed estimation algorithms, one ADMM-based and one JACOBI-like, in order to

Processing of intractable polymers using reactive solvents : 6. a new reactive solvent concept based on reversible depolymerisation

, 2002
The use of reactive solvents which reversibly (de)polymerise to facilitate the processing of poly(2,6-dimethyl-1,4-phenylene ether) (PPE) was explored. PPE can be dissolved at elevated temperatures in very low molecular weight thermoplastic poly(urethane)

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Micromechanical deformation processes in toughened PP/PA/SEBS-g-MA blends prepared by reactive processing

, 1998
Toughening mechanisms occurring in PP/PA6 (70 vol.-%/30 vol.-%) blends containing various amounts of SEBS-g-MA have been studied by in situ straining in a high voltage electron microscope (HVEM). Variation of volume fraction of compatibilizer (SEBS-g-MA)
