Peptomer Linkers Enable Kinetic Control over Co‐Delivery of Multiple Chemotherapeutics

Advanced Healthcare Materials, EarlyView.
A key challenge in combinatorial chemotherapeutic drug delivery is independent control over release kinetics, especially with drugs of similar size and structure. Here, peptoid substitutions to proteolytically degradable peptides enabled the design of fast and slow‐releasing drug linkers.

Progress in South America Dendrochronology [PDF]

, 2002
South America extends from 11°N to 62°S. Major boundaries such as the Andes on the western side of the continent and the land mass in the tropics create north-south and west-east variations in climate and ecosystems.

Un cementerio incásico en Chile Central

Boletín 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

Gayana (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 ...

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

Advanced 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

The Andes mountain range uplift as a vicariant event in the Pimeliinae (Coleoptera: Tenebrionidae) in southern South America [PDF]

, 2006
The Andes mountain range extends over 8500 km along the Pacific coast of South America. Its medium altitude is 3500 m, reaching more than 6000 m at different latitudes. The uplift of the Andes  split arid habitats creating very diverse ecosystems on both

Freeform Manufacturing of Plant‐Based Structural Colors for Scalable Photonic and Mechanochromic Devices

Advanced Materials, EarlyView.
A green, freeform manufacturing approach that utilizes robust aqueous two‐phase systems to create intricate and scalable photonic structures and non‐planar mechanochromic hydrogel actuators from plant‐based hydroxypropyl cellulose. This approach broadens the structural possibilities of sustainable photonic devices and mechanochromic systems, offering ...

Tornado Seasonality in Central‐Southern Chile

Geophysical 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
