Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

open access: yesAdvanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Un cementerio incásico en Chile Central

open access: yesBoletín Museo Nacional de Historia Natural, 1947
El cementerio que forma el objeto de este trabajo es de interés especial para la arqueología chilena, porque es la primera vez que ha sido posible excavar sistemáticamente en Chile Central un yacimiento arqueológico, previamente no tocado. Ya con anterioridad piezas sueltas han encontrado su camino hacia las colecciones públicas, pero siempre provenían

FEATURING ENSO 1997-2000 IN CENTRAL CHILE

open access: yesGayana (Concepción), 2004
Using satellite images of the area between 32-36°S and 71-75°W, from October 1997 to September 1999, temporal and spatial variability of sea surface temperature (SST) was analyzed. During this period of time, one of the most intense episode of the last century of the warm phase (El Niño) and the beginning of the cold phase (La Niña) of the ENSO cycle ...

Tornado Seasonality in Central‐Southern Chile

open access: yesGeophysical Research Letters
AbstractTornado records in Chile show an apparent seasonality with a peak between May and June. We study this seasonality in central‐south and austral Chile by analyzing three indicators of tornado environments: vorticity generation parameter (VGP), storm‐relative helicity (SRH) and mean relative humidity . Annual cycles of VGP, SRH and show favorable
