Recently, leaf protein concentrate (LPC) has gained increased attention in response to the constantly growing protein demand. Green biorefineries can become more economical by valorizing their by-products and reducing environmental risks. The current study describes the variations in the antioxidant capacity and phytochemical composition of a liquid by-product (referred to as brown juice (BJ)) obtained during the extraction of leaf protein concentrate (LPC) from the fresh biomass of alfalfa ( L.

- When atoms are placed in liquids like superfluid helium, their optical spectral lines get significantly broader, complicating high-resolution spectroscopy.
- However, when an exotic atom containing an antiproton is embedded in superfluid helium, its spectral line maintains a very narrow linewidth, allowing for better observation of hyperfine structures.
- This advancement suggests that laser spectroscopy can be used to study other exotic particles in superfluid helium, potentially aiding in the detection of cosmic-ray antiprotons and antideuterons.
We review recent experiments carried out by the PiHe collaboration of the Paul Scherrer Institute (PSI) that observed an infrared transition of three-body pionic helium atoms by laser spectroscopy. These measurements may lead to a precise determination of the charged pion mass, and complement experiments of antiprotonic helium atoms carried out at the new ELENA facility of CERN.

We examined the effect of non-fermented and lacto-fermented alfalfa brown juice (BJ) on seed germination and the vegetative, physiological, and anatomical properties of French marigold ( L. 'Csemő') plants which were treated with 0.

Laser spectroscopy of these atoms should permit the mass and other properties of the meson to be determined with high precision and could place upper limits on exotic forces involving mesons (as has been done in other experiments on antiprotons).
