A Compact Hollow Fiber Electrode Assembly Architecture for Continuous Electrochemical Marine Carbon Dioxide Removal

open access: yesAdvanced Energy Materials, EarlyView.
A coaxial, membrane‐integrated hollow fiber electrode assembly (HFEA) is developed for continuous marine carbon mineralization. By utilizing a sub‐millimeter inter‐electrode gap, the HFEA minimizes Ohmic losses, achieving 50% energy reduction and over 85% DIC removal.

Distribution of Big Tau Isoforms in the Human Central and Peripheral Nervous System

open access: yesAnnals of Neurology, EarlyView.
Objective Tau is widely studied in neurodegeneration, yet most work has focused on canonical brain tau isoforms. A longer isoform, “big tau,” produced by inclusion of exon 4a, is expressed in the peripheral nervous system (PNS) and central nervous system (CNS) regions.

Power saving techniques for 5G RRC_Idle mode UE

open access: yesDianxin kexue, 2021
The power consumption of 5G UE is much serious than 4G UE due to larger bandwidth, massive MIMO, and higher data rate and has been one of the important reason affecting users’ experience of 5G network.3GPP has promoted the study and standardization of NR

Eine Interphase mit ortsfesten Ladungen synchronisiert den Ionentransport und unterdrückt raumladungsgetriebene Ineffizienz unter räumlicher Begrenzung auf Nanoliter‐Volumina

open access: yesAngewandte Chemie, EarlyView.
Die elektrochemische Energiespeicherung stößt bei extremer Miniaturisierung an fundamentale Grenzen, da Grenzflächen‐ und Raumladungseffekte dominieren. Hier stellen wir eine selektive Interphase mit ortsfesten Ladungen in einer Zwillingsrohr‐μ‐Swiss‐Roll‐Architektur vor.

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.
