Hybrid Spring‐Coupled Broadband Energy Harvester Integrated with CuSCN Functionalized Triboelectric Vibration Sensor for Self‐Sustainable Vehicular IoTs

open access: yesAdvanced Science, EarlyView.
A self‐sustainable vehicular vibration and indoor environment monitoring IoT platform is developed which integrates a hybrid spring‐coupled broadband energy harvester with a machine learning‐assisted PAN‐CuSCN nanofiber triboelectric vibration sensor for subtle‐to‐wide‐range vibration detection and road/speed classification.

Probing signals of atmospheric gravity waves excited by the July 29, 2021 MW8.2 Alaska earthquake

open access: yesGeodesy and Geodynamics
It is commonly believed that the atmosphere is decoupled from the solid Earth. Thus, it is difficult for the seismic wave energy inside the Earth to propagate into the atmosphere, and atmospheric pressure wave signals excited by earthquakes are unlikely ...

Interface Rectification via Roll‐to‐Roll Dual‐Confinement Nanocoatings for High‐Temperature Polymer Capacitors

open access: yesAdvanced Science, EarlyView.
Dual confinement in self‐assembled nanocoatings regulates polymer dynamics and hot‐carrier transport, enabling an interface‐rectification strategy for high‐temperature polymer capacitive energy storage. ABSTRACT Polymer film capacitors are indispensable for energy storage and power conversion, yet their energy density and efficiency deteriorate rapidly

Habitat‐Specific Design Strategies for Untethered Soft Robots

open access: yesAdvanced Science, EarlyView.
Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...

Hybrid Semi‐Transparent Perovskite‐Photovoltaics and Concentrated Solar‐Thermal Harvesting Collectors

open access: yesAdvanced Science, EarlyView.
A hybrid semi‐transparent perovskite‐photovoltaic and concentrating solar‐thermal collector is developed to spectrally split sunlight for simultaneous electricity and heat generation. The design achieves thermal decoupling between the photovoltaic and thermal components, offering a promising route for efficient co‐harvesting of solar electricity and ...

Virtual Gravity and the Duality of Reality [PDF]

open access: yes, 2003
It is shown that a hypothesis about gravity having a virtual cause implies there are two primary reference frames, a reality and a functional virtual reality and an equivalence principle relating the two is postulated.

Not All Agreements Are Equal: Heterogeneous Effects of RTAs on Latin American Agri‐Food Exports, 1990–2019

open access: yesAgribusiness, EarlyView.
ABSTRACT Since the final decade of the 20th century, Latin American countries have increasingly regarded the signing of regional trade agreements (RTAs) as a promising strategy for expanding their exports. Within this context, the main objective of this study is to assess the impact of RTAs on agri‐food exports in Latin America over the period 1990 ...
