Needle‐free, Liquid Metal‐embedded Electrospray Deposition System for Controlled Microdroplet Printing

open access: yesAdvanced Science, EarlyView.
The liquid metal‐embedded electrospray deposition (LM‐ESD) system combines stable droplet spray, clog‐free and recoverable operation, and simplified fabrication in a single polydimethylsiloxane (PDMS) microfluidic platform. By eliminating external electrodes, it offers needle‐free, robust, and scalable droplet array printing, ensuring reproducibility ...

More Tickets, Fewer Accidents: How Cash-Strapped Towns Make for Safer Roads [PDF]

open access: yes
Traffic accidents are one of the leading causes of injury and death in the U.S. The role of traffic law enforcement in the reduction of accidents has been studied by relatively few papers and with mixed results that may be due to a simultaneity problem ...

Two Types of Non‐Abelian Topological Phase Transitions Under Duality Mapping in 1D Photonic Chains

open access: yesAdvanced Science, EarlyView.
In this work, two types of non‐Abelian phase transitions are revealed. The first type is the braided‐node type, signified by the Dirac degeneracy node moving into or out of the unit circle. The second type corresponds to the emerging of nodal‐line degeneracy which intersects with unit circles.

Breath, Pulse, and Speech: A Multi‐Parameter Wearable System using Airflow‐Thermoelectric Fusion Technology

open access: yesAdvanced Science, EarlyView.
For insufficient medical emergency monitoring, this study develops a wearable system with flexible thermoelectric textiles and thermoelectric‐optical sensing. It establishes a dynamic airflow‐thermoelectric response theory (enabling 98% speech recognition) and a multi‐source fusion model for 98% emergency state recognition, aiding clinical decision ...

Electrically and Geometrically Tunable Photon Pair Entanglement from Ferroelectric Nematic Liquid Crystal

open access: yesAdvanced Science, EarlyView.
By exploiting the strong nonlinear optical response and controllable molecular ordering of ferroelectric nematic liquid crystals (FNLCs), these materials can serve as tunable sources of polarization‐entangled photons. Adjusting the sample geometry or applying an external electric field enables continuous control of the entanglement degree, advancing ...
