Multibit Ferroelectric HfZrO Memcapacitor for Non‐Volatile Analogue Memory and Reconfigurable Electronics

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectric memcapacitors enable non‐volatile, voltage‐programmable capacitance tuning for adaptive electronics. A TiN/HfZrO/TiN device stack demonstrates more than eight stable capacitance states within a 24 pF memory window in compact 60 ×$\times$ 60 μm2$\umu{\rm m}^{2}$ devices at low operating voltages.

Investigating GNSS PPP–RTK with external ionospheric constraints

open access: yesSatellite Navigation, 2022
Real-Time Kinematic Precise Point Positioning (PPP–RTK) is inextricably linked to external ionospheric information. The PPP–RTK performances vary much with the accuracy of ionospheric information, which is derived from different network scales, given ...

Radical‐Mediated, Substrate‐Independent Fabrication of Hybrid Solid–Hydrogel Materials With Tunable Crosslinking: An Initiator‐ and Crosslinker‐Free Approach

open access: yesAdvanced Science, EarlyView.
This work introduces a substrate‐independent, reagent‐free plasma strategy that forms radical‐rich interlayers for covalent hydrogel attachment without initiators or crosslinkers. The long‐lived radicals drive in situ gelation, creating robust, cytocompatible hybrid solid–hydrogel constructs across diverse substrates.

Conversion of Transplanted Mature Hepatocytes into Afp+ Reprogrammed Cells for Liver Regeneration After Injury

open access: yesAdvanced Science, EarlyView.
Donor‐derived tdTomato+ mature hepatocytes were FACS‐isolated and transplanted into Fah−/− host mice. During regeneration, these cells convert into proliferative, unipotent Afp+ rHeps. Their plasticity is governed by a PPARγ/AFP‐dependent metabolic switch, segregating into pro‐proliferative Afplow and pro‐survival Afphigh subpopulations.

Hierarchical MXene–Carbon Nanotube Architectures for High‐Stability Silicon Oxide Anodes

open access: yesBatteries &Supercaps, EarlyView.
A novel MXene–CNT hierarchical framework is synthesized via molecularly driven assembly and crosslinking, enabling electrically interconnected and mechanically reinforced Si/SiOx/C composite anodes. The CNTs bridge the MXene flakes to form a robust conductive network, while the MXene surface chemistry facilitates uniform SiOx/C coating and SEI ...

A feedback loop between the androgen receptor and 6-phosphogluoconate dehydrogenase (6PGD) drives prostate cancer growth

open access: yeseLife, 2021
Alterations to the androgen receptor (AR) signalling axis and cellular metabolism are hallmarks of prostate cancer. This study provides insight into both hallmarks by uncovering a novel link between AR and the pentose phosphate pathway (PPP ...

Turning Carbon Into Cash? Cross‐Country Evidence on the Profitability of Emission Reductions

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Does corporate CO2 abatement pay? We assembled an international panel of listed firms (2019–2023), linking Scope 1–2 emissions to institutional (G7, CCPI) and search‐based attention measures. The dataset consists of an unbalanced panel of 1724 multinational firms, together with a sub‐sample of 922 firms operating in G7 economies. Firm and time

Assessment of global and regional UPD for BDS/GNSS PPP-AR at low latitudes during quiet and geomagnetic storm periods

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
The resolution of ambiguity (AR) is of paramount importance for the precise point positioning (PPP) technique, as it enables the reduction of convergence duration and the improvement of positioning accuracy. Uncalibrated phase delay (UPD) is a key factor
