Tropical tree growth driven by dry-season climate variability
Zuidema, Pieter A.; Babst, Flurin; Groenendijk, Peter; Trouet, Valerie; Abiyu, Abrham; Acuña-Soto, Rodolfo; Adenesky-Filho, EduardoInterannual variability in the global land carbon sink is strongly related to variations in tropical temperature and rainfall. This association suggests an important role for moisture-driven fluctuations in tropical vegetation productivity, but empirical evidence to quantify the responsible ecological processes is missing. Such evidence can be obtained from tree-ring data that quantify variability in a major ve...
Efficient and tuneable photoluminescent boehmite hybrid nanoplates lacking meta...
Bai, Xue; Caputo, Gianvito; Hao, Zhendong; Freitas, Vania T.; Zhang, Jiahua; Longo, Ricardo L.; Malta, Oscar L.; Ferreira, Rute A. S.; Pinna, NicolaWhite light-emitting diodes (WLEDs) are candidates to revolutionize the lighting industry towards energy efficient and environmental friendly lighting and displays. The current challenges in WLEDs encompass high luminous efficiency, chromatic stability, high colour-rending index and price competitiveness. Recently, the development of efficient and low-cost downconverting photoluminescent phosphors for ultraviol...
The 'silence' of silent brain infarctions may be related to chronic ischemic pr...
Feng, Chao; Bai, Xue; Xu, Yu; Hua, Ting; Liu, Xue-YuanOBJECTIVE: Silent brain infarctions are the silent cerebrovascular events that are distinguished from symptomatic lacunar infarctions by their 'silence'; the origin of these infarctions is still unclear. This study analyzed the characteristics of silent and symptomatic lacunar infarctions and sought to explore the mechanism of this 'silence'. METHODS: In total, 156 patients with only silent brain infarctions, 9...
Zirconia-doped nanoparticles: organic coating, polymeric entrapment and applica...
Rebuttini, Valentina; Pucci, Andrea; Arosio, Paolo; Bai, Xue; Locatelli, Erica; Pinna, Nicola; Lascialfari, Alessandro; Franchini, Mauro ComesZirconia nanoparticles doped with Eu3+, Tb3+ and Gd3+ ions have been synthesized following the benzyl alcohol route. The nanoparticles were coated with N-hydroxydodecanamide and encapsulated in PLGA-b-PEG-COOH nanomicelles. The magnetic and fluorescent properties of these hybrid nanocarriers were investigated, proving them to be potential dual-imaging contrast agents.
