La madera varía entre las especies, desde la médula hasta la corteza, desde las raíces hasta la corona dentro de la misma planta, para garantizar la seguridad y la eficiencia hidráulica. La heterogeneidad de la madera de Inga laurina (Sw.) Willd. es aquí investigada, siendo una especie que prospera bien en todos los bosques brasileños importantes. La madera de tallo de I. laurina poseía vasos estrechos; fibras de paredes gruesas; rayos más anchos, altos y en mayor frecuencia, características que proporcionan ajustes hidráulicos y mecánicos. Las fibras de paredes gruesas y menos parénquima, en comparación con la raíz, brindan la fuerza suficiente para apoyar la corona grande. Una mayor proporción de células de parénquima en las raíces da como resultado una gran capacidad de almacenamiento de almidón, que es importante para la recuperación de los brotes después del daño por fuego, común en el Cerrado. Wood varies between species, from pith to bark, roots to crown within the same plant to ensure hydraulic safety and efficiency. Inga laurina (Sw.) Willd. is investigated herewith for the structural heterogeneity of the wood, since this species thrives well in all major forests of Brazil. I. laurina stem wood possessed narrow vessels; thick walled fibres; wider, taller and higher frequency of rays, features that provide hydraulic and mechanical adjustments. Thick walled fibres and less parenchyma as compared to root provide enough strength to stem to support the large crown. Higher proportion of parenchyma cells in roots results in a high storage capacity for starch, which is important for the shoot recovery after fire damage, common in the Cerrado.

In this work we report on the thermoluminescence (TL) and optically stimulated luminescence (OSL) properties of β-Na(Gd,Lu)F4:Tb3+ nanophosphors prepared via a standard high-temperature coprecipitation route. Irradiating this phosphor with X-rays not only produces radioluminescence but also leads to a bright green afterglow that is detectable up to hours after excitation has stopped. The storage capacity of the phosphor was found to be (2.83 ± 0.05) × 1016 photons/gram, which is extraordinarily high for nano-sized particles and comparable to the benchmark bulk phosphor SrAl2O4:Eu2+,Dy3+. By combining TL with OSL, we show that the relatively shallow traps, which dominate the TL glow curves and are responsible for the bright afterglow, can also be emptied optically using 808 or 980 nm infrared light while the deeper traps can only be emptied thermally. This OSL at therapeutically relevant radiation doses is of high interest to the medical dosimetry community, and is demonstrated here in uniform, solution-processable nanocrystals.
