Large‐Area 2D Metasurface‐Based Triboelectric E‐Skin Arrays: Contact & Proximity Tactile Mapping with Broadband Acoustic Readouts

open access: yesAdvanced Materials, EarlyView.
Metasurface‐engineered NC‐TENG arrays integrate tactile pressure mapping, non‐contact gesture sensing, and acoustic signal readouts in one ultrathin module, and outperforms pristine PDMS in terms of electrical output and real‐time spatial mapping for next‐gen wearables.

Sea slugs (Gastropoda: Heterobranchia) from Huatulco: new records and distribution range extensions for Oaxaca, Mexico

open access: yesRevista Mexicana de Biodiversidad
While the diversity of sea slugs in the northern area of the Pacific coast of Mexico has been studied thoroughly in the last decades, little is known about the composition of species in the southern states of Mexico.

The Saposin-Like Protein AplD Displays Pore-Forming Activity and Participates in Defense Against Bacterial Infection During a Multicellular Stage of Dictyostelium discoideum

open access: yesFrontiers in Cellular and Infection Microbiology, 2018
Due to their archaic life style and microbivor behavior, amoebae may represent a source of antimicrobial peptides and proteins. The amoebic protozoon Dictyostelium discoideum has been a model organism in cell biology for decades and has recently also ...

3D‐Printed Arch‐Structured Tribolayer with Conducting Polymer Coating for Enhanced Triboelectric Energy Harvesting

open access: yesAdvanced Materials Interfaces, EarlyView.
PEDOT:PSS‐coated 3DP microstructures are introduced to realize TENGs with enhanced mechanical compliance and high electrical performance. Among the investigated geometries, arch‐shaped microstructures exhibit superior fatigue resistance due to their spring‐like behavior, enabling efficient stress distribution, stable contact evolution, and sustained ...

Evolving Starburst Modeling of FIR/sub-mm/mm Line Emission. III. Application to Nearby Luminous Infrared Galaxies

open access: yes, 2009
In a previous work, we showed that the observed FIR/sub-mm/mm line spectra of a starburst galaxy (M 82) can be successfully modeled in terms of the evolutionary scheme of an ensemble of giant molecular clouds (GMCs) and shells, and such studies can ...

Assessment of the Biological Control Potential of Common Carabid Beetle Species for Autumn- and Winter-Active Pests (Gastropoda, Lepidoptera, Diptera: Tipulidae) in Annual Ryegrass in Western Oregon

open access: yesInsects, 2020
While carabid beetles have been shown to feed on a variety of crop pests, little is known about their species assemblages in US annual ryegrass crops, where invertebrate pests, particularly slugs, lepidopteran larvae and craneflies, incur major financial

Characterization and Design Framework for Micro‐ and Nanoscale Printed Metal Interconnects in Hybrid Electronic Systems

open access: yesAdvanced Materials Technologies, EarlyView.
This work establishes a framework for high‐resolution printed interconnects by coupling e‐jet printing control, multilayer deposition, and sintering optimization. Ink properties and printing speed influence particle stacking, while different sintering atmospheres drive distinct microstructural evolution.

Spitzer Observations of Cold Dust Galaxies

open access: yes, 2009
We combine new Spitzer Space Telescope observations in the mid- and far-infrared with SCUBA 850 micron observations to improve the measurement of dust temperatures, masses and luminosities for 11 galaxies of the SCUBA Local Universe Galaxy Survey (SLUGS).
