Chilling and Heat Requirements of Temperate Stone Fruit Trees (Prunus sp.)
Agronomy, 2020 Stone fruit trees of genus Prunus, like other temperate woody species, need to accumulate a cultivar-specific amount of chilling during endodormancy, and of heat during ecodormancy to flower properly in spring.

Los relieves invertidos en los globos virtuales
Ágora de Heterodoxias, 2015 Una mayoría de los usuarios de los Globos Virtuales (Google Maps, Microsoft Bing, Apple Maps etc.) ve un relieve que es inverso al real (cordilleras que en realidad son vaguadas y ríos que en realidad son cadenas montañosas) sin ser conscientes de ello ...

Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD
Advanced Materials, EarlyView.Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Effects of soil salinity on the quality of ‘Arbequina' olive oil
Grasas y Aceites, 2005 This work analyzes the effect of soil salinity on olive oil quality. The chemical composition of oils extracted from young ‘Arbequina' olives subject in the field to three soil salinity levels (low-L, medium-M and high-H) was determined throughout a ...

Advanced Materials, EarlyView.Sub‐stoichiometric amounts of Na+ or K+ enhance defect healing during Silicalite‐1 (MFI) and TS‐1 calcination by promoting Si–O–Si annealing and healing framework vacancies. The resulting defect‐free zeolites are more hydrophobic and show improved butanol/water separation and improved activity and selectivity in the epoxidation of 1‐hexene, offering a ...

Hamaker Constants of van der Waals Materials under Clean‐Interface Conditions
Advanced Science, EarlyView.Clean‐interface adhesion in representative van der Waals materials is quantified by Ultra High Vacuum (UHV) Atomic Force Microscopy (AFM) with in situ cleaning and calibrated probes. Benchmark Hamaker constants for graphene, MoS2, and SiO2 are established, while humidity is shown to reversibly amplify adhesion, explaining much of the scatter in ...
