Effects of 12-Week Moderate-Intensity Versus High-Intensity Water-Aerobic Training on Physical Fitness, Cardiovascular Health, and Well-Being in Adults and Older Adults: A Pragmatic Randomized Controlled Trial.

Background And Aims: The current study aimed to compare the effects of 12 weeks of moderate versus high-intensity water aerobics on muscle strength, body composition, lipid profile, blood pressure, and quality of life in both adults and older adults.

Methods: Twenty-one women (65.19 ± 9.

Hierarchical Porous FeC@Fe-N-C Catalysts from Tannin-Fe(III) Complexes for Efficient Oxygen Reduction.

The rational design of metal-nitrogen-doped carbons (M-N-C) from available and cost-effective sources featuring high electrocatalytic performance and stability is attractive for the development of viable low-temperature fuel cells. Herein, mimosa tannin, an abundant polyphenol easily extracted from the Mimosa plant, is used as a natural carbon source to produce a tannin-Fe(III) coordination complex. This process is assisted by Pluronic F127, which acts as both a surfactant and a promoter of Fe-N active sites.

The Heisenberg-RIXS instrument at the European XFEL.

Resonant inelastic X-ray scattering (RIXS) is an ideal X-ray spectroscopy method to push the combination of energy and time resolutions to the Fourier transform ultimate limit, because it is unaffected by the core-hole lifetime energy broadening. Also, in pump-probe experiments the interaction time is made very short by the same core-hole lifetime. RIXS is very photon hungry so it takes great advantage from high-repetition-rate pulsed X-ray sources like the European XFEL.
