PLANTS, PEOPLE, PLANET, EarlyView.Brazil's diverse flora is under several threats, with many unique lineages facing extinction, particularly in biodiverse regions like the Cerrado and campo rupestre. This study sheds light on the conservation needs of Cambessedesia (Melastomataceae), an endemic genus with 95% of its species endangered, using an approach to rank and prioritise species ...

Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity
PLANTS, PEOPLE, PLANET, EarlyView.The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

Luminescence of Tb3+ and Eu3+ Single‐Doped and Double‐Doped LiSrVO4 Phosphors
physica status solidi (b), EarlyView.Typical emissions of Tb3+ and Eu3+ ions and the energy transfer mechanism from Tb3+ to Eu3+ are observed when excited at 345 nm. The emission intensity of Tb3+, Eu3+‐doped LiSrVO4 is enhanced by Eu doping. The CIE coordinates of the phosphors can be tuned from orange to red by changing the Eu doping.

Physical activity and affect of the elderly: Contribution to the validation of the Positive and Negative Affect Shedule (PANAS) in the Portuguese population [PDF]
, 2019 The concept of affect corresponds to the emotional dimension of subjective well-being (Diener, Emmons, Larsen, & Griffin, 1985). It is represented by two dimensions (negative affect and positive affect), which were the basis of the development of the ...

physica status solidi (RRL) – Rapid Research Letters, EarlyView.Energetic particles make space a harsh environment that solar cells must endure. This study demonstrates that proton flux critically affects radiation damage in Cu(In,Ga)Se2 solar cells. By irradiating identical cells at different fluxes, a flux‐dependent balance between defect generation and dynamic annealing was revealed.
