Advanced Science, EarlyView.Drop‐location sensitivity remains a key barrier to practical droplet‐based electricity generators (DEGs). Here, a polydimethylsiloxane slippery covalently attached liquid (PDMS‐SCAL)‐coated interface promotes droplet sliding instead of splitting or bouncing, allowing stable electricity generation from randomly falling raindrops. The resulting PDMS‐SCAL‐

Global flow behaviors of multiple shafts in shallow-buried urban road tunnels subjected to fire load
Underground SpaceShallow-buried urban road tunnels with shafts (URTS) have reduced traffic congestion in large cities. During fire scenarios, the backflows occur at those shafts far away from the fire source inhibiting smoke exhaust, but its rules have been unknown.

Lymphatic Abnormalities in Noonan Syndrome Extend Beyond Clinically Apparent Disease
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Lymphatic disease represents a well‐described manifestation of Noonan syndrome (NS), yet the full phenotypic spectrum remains incompletely characterized, especially in asymptomatic individuals. We conducted a cross‐sectional study including 10 individuals with NS (four with peripheral lymphedema and six without) and 10 age‐ and sex‐matched ...

A General Workflow for Tangential Flow Filtration Perfusion Scale‐Up
Biotechnology and Bioengineering, EarlyView.ABSTRACT Tangential flow filtration (TFF) perfusion using hollow‐fiber modules offers substantial advantages over other mammalian cell retention technologies. Recently, increased awareness of Starling flow has helped to enhance filtration performance to similar, or even higher levels compared to alternative technologies.

Journal of Physics: Conference SeriesAbstract This paper proposes a single-stage isolated converter with a backflow power optimization method for V2G charging piles. The modulation algorithm is optimized, and the phase shifts are designed to minimize the backflow power. Due to the suppression of backflow power during the switching period, the power factor correction (PFC ...
