Localization of Aluminum in Epidermal Cells of Mature Tea Leaves

Quantum Beam Science, 2019
We have determined the distribution of aluminum in the epidermal cells of mature tea leaves using micro-beam particle-induced X-ray emission. The observed pattern of aluminum distribution in the epidermal cells suggests that aluminum exists in cell walls.

Laser-based techniques for the non-invasive characterisation of grisaille paints on stained-glass windows

Heritage Science, 2023
Grisaille was the first paint applied on stained-glass panels, used in Europe since the twelfth century. Historical written sources described the use of iron and copper together with a high lead-silica base glass in the grisailles production.

Fate of nickel and calcium in seedlings of the hyperaccumulator Berkheya coddii during germination

Biologia Plantarum, 2015
Little is known about Ni storage in seeds of hyperaccumulating plants and its possible role in the first stages of plant development. The aim of this study was to determine Ni distribution in seeds and seedlings during germination and to test its role ...

Application of laser produced ion beams to nuclear analysis of materials

EPJ Web of Conferences, 2013
The ion beam driven nuclear analysis has been developed for many years by using various electrostatic accelerators. A proton micro-beam with the beam diameter of ∼1.5 μm at Takasaki Ion Acceleration for Advanced Radiation Application (TIARA), JAEA was ...

Zinc allocation to and within Arabidopsis halleri seeds: Different strategies of metal homeostasis in accessions under divergent selection pressure

Plant-Environment Interactions, 2020
Vegetative tissues of metal(loid)‐hyperaccumulating plants are widely used to study plant metal homeostasis and adaptation to metalliferous soils, but little is known about these mechanisms in their seeds.
