We investigate magnesium-iron pyroborate MgFeBO as a potential cathode material for rechargeable magnesium-ion batteries. Synchrotron powder X-ray diffraction and Mössbauer spectroscopy confirm its successful synthesis and iron stabilization in the high-spin Fe(II) state. Initial electrochemical testing against a lithium metal anode yields a first charge capacity near the theoretical value (147.

Metal-air batteries are promising energy storage systems with high specific energy density and low dependence on critical materials. However, their development is hindered by slow kinetics, low roundtrip efficiency, deficient capacity recovery, and limited lifetime. This work explores the effect of cycling protocols on the lifetime of Li-O cells, and the interplay between electrolyte composition and the upper cut-off voltage during charge.

The aim of this study was to give insights on the effects of an industrially relevant kilning method, with a focus on lipase inactivation and oat-base production. Storage of non-kilned, dehulled oat kernels in either room temperature or at 37 °C for up to 64 days led to increasing lipase activity with time, despite a decrease in moisture content and water activity, demonstrating the importance of kilning before storage. It was shown that the temperature and relative humidity used during the kilning had a major impact on both protein solubility and lipase inactivation.

Article Synopsis
  • Glucuronic acid (GlcA) and its methylated form (MeGlcA) are key components of hardwood xylan that can impact digestibility.
  • Current methods for detecting these acids from synthetic substrates are effective, but analyzing them in natural substrates like xylan presents challenges.
  • This study proposes new gradient elution protocols using HPAEC-PAD to enhance the separation and quantification of GlcA and MeGlcA in hardwood samples, demonstrating excellent reproducibility and reliable results.

Cortical signals have been shown to track acoustic and linguistic properties of continuous speech. This phenomenon has been measured in both children and adults, reflecting speech understanding by adults as well as cognitive functions such as attention and prediction. Furthermore, atypical low-frequency cortical tracking of speech is found in children with phonological difficulties (developmental dyslexia).
