Planetary magnetospheres

open access: yesGeofísica Internacional, 1991
La serie de naves espaciales Pionero, Marinero y Viajero nos ha dado a conocer una impresionante variedad de magnetosferas planetarias. Debido a su cercanía, la magnetosfera terrestre es la que mejor entendemos. El viento solar provee parte del plasma y,

Dual‐Interface Engineering of the Source Electrode to Overcome the Intrinsic Injection‐Leakage Trade‐Off in Organic Schottky Barrier Transistors

open access: yesAdvanced Functional Materials, EarlyView.
A charge injection layer is introduced via RIE to decouple the dual functions of the source electrode: lowering contact resistance through doping to enhance charge injection, while SAM modification on the top surface minimizes leakage current. This strategy enables OSBTs to achieve a high on/off ratio with improved stability and performance.

The role of climate and population change in global flood exposure and vulnerability

open access: yesNature Communications
Flooding is a pervasive natural hazard with wide-ranging impacts on society. Using a high-resolution global flood model considering coastal, fluvial, and pluvial hazards, we clarify the role of climate effects versus population growth effects in changing

Myocardial Strain Imaging Using Feature Tracking Method of Cardiac MRI: Our Initial Experience of This Novel Parameter as an Additional Diagnostic Tool

open access: yesIndian Journal of Radiology and Imaging, 2022
Background Left ventricular ejection fraction (LVEF) is used as quantitative parameter to evaluate myocardial function. However, interobserver variation, limited reproducibility, and dependence on pre-load and after-load reduces its accuracy. The fall in

Selection of a common communication link geometry for Saturn, Uranus and Titan [PDF]

open access: yes, 1974
Mission analysis link parametrics, considering a Pioneer baseline, are developed through launch energies, flyby radii, and trip time calculations. Projected is also a 1979 Jupiter Uranus opportunity for a derivative Mariner to fly to Uranus by using the ...

Introducing Pure Calcium Orthophosphate Gels and Aerogels

open access: yesAdvanced Functional Materials, EarlyView.
The synthesis of calcium phosphate‐based gels and aerogels is reported, which exhibit highly porous structures built up of networks of nanoparticles. In case of amorphous aerogels, this leads to yet unmatched specific BET surface areas, making these materials especially interesting for biomedical applications.

Photoactivated Proximity Protein Labeling Reveals Enhanced Tumor Retention of a D‐Peptide‐Ruthenium Prodrug Conjugate

open access: yesAdvanced Healthcare Materials, EarlyView.
Six stereoisomeric ruthenium‐peptide conjugates were synthesized and characterized, which showed high potential in photoactivated chemotherapy (PACT) and proximity protein labeling. Abstract Amino acid chirality is known to influence the biological properties of peptide‐containing prodrugs.

Rapid Formation of Saturn after Jupiter Completion

open access: yes, 2012
We have investigated Saturn's core formation at a radial pressure maximum in a protoplanetary disk, which is created by gap opening by Jupiter. A core formed via planetesimal accretion induces the fragmentation of surrounding planetesimals, which ...

Stimuli‐Responsive Afterglow from Luminescent Liquid Crystal Elastomers

open access: yesAdvanced Materials, EarlyView.
An active glow luminescent system for encoding, signaling, and tracking in dark environments has been developed by integrating inorganic ultralong afterglow phosphors with adaptive liquid crystal elastomer actuators. Abstract Stimuli‐responsive luminescent polymeric materials which combine afterglow emission with mechanical flexibility and adaptability
