Achieving High‐Density and Stress‐Resilient Maize Breeding Via Germplasm Innovation

open access: yesAdvanced Science, EarlyView.
Global population growth and climate change have exacerbated the global food crisis. This perspective presents a conceptual framework focusing on enhancing population advantages. Several novel breeding objectives are proposed to improve density tolerance and stress resistance for yield improvement.

Improved computer modeling of ship progressive flooding as a design tool [PDF]

open access: yes, 1998
When a ship suffers underwater damage, there is a rapid influx of water, followed by a period of slower progressive flooding. This results in flooding of compartments whose hull boundaries, but not interior bulkheads, are still intact.

Mass‐Transport–Engineered CCM Architecture Employing MPL‐Free Carbon Paper and Graphene‐Coated Ni Foam Channels for High‐Temperature PEM Fuel Cells

open access: yesAdvanced Science, EarlyView.
A CCM‐based architectural strategy is introduced for high‐temperature PEM fuel cells, enabling MPL‐free carbon paper gas diffusion layers via decal‐transfer processing. By co‐engineering the CCM, GDL, and a G‐foam flow field, oxygen transport is enhanced while phosphoric‐acid leakage is suppressed, resulting in high power density and stable operation ...

Modeling the progressive flooding characteristics of the Arleigh Burke Class Destroyer using SIMSMART and Excel [PDF]

open access: yes, 2000
The goal of this thesis is to contribute further to the development of a design tool for the modeling of dynamic progressive flooding in ships. In an earlier thesis, LT Thomas Anderson, USN, modeled a generic, mathematically describe able hull form; in ...

Responses of two hybrid Populus clones to flooding, drought, and nitrogen availability. II. Gas exchange and water relations [PDF]

open access: yes, 1993
Repeated progressive drought and flooding stress were imposed on two hybrid poplar clones (Populus×euramericana 'Eugenei' and P. tristis × P. balsamifera 'Tristis') grown under two levels of nitrogen.

High Free‐Volume Imidazole‐Based Ionomers for High‐Temperature Proton Exchange Membrane Fuel Cells

open access: yesAdvanced Science, EarlyView.
High free‐volume imidazole‐based ionomers (PF4IM‐72) enable enhanced phosphoric acid uptake and efficient proton transport, delivering peak power densities of 0.645 W cm−2 at 160 °C and 0.838 W cm−2 at 200 °C in HT‐PEMFCs. This work highlights a promising platform for next‐generation ionomers with improved high‐temperature performance and stability ...

Non-invasive monitoring of hydraulic processes in the rhizosphere using shortwave infrared imaging [PDF]

open access: yesE3S Web of Conferences
Existing methods for non-destructive, ex-situ investigation of the rhizosphere include X-Ray Computed Tomography. However, this method is time-consuming, requires specialist skills to operate, and, most of all, it is impractical for multiple replications.

If not now, when? Climate disaster and the Green vote following the 2021 Germany floods

open access: yesResearch & Politics, 2022
Can first-hand experience of a climate-related natural disaster make citizens more likely to vote in favour of progressive climate politics? Leveraging the rare occurrence of a large-scale disaster just two months before a federal election, we use a ...

Hormonal Modulation of Citrus Responses to Flooding [PDF]

open access: yes, 2008
In this work, variations in endogenous levels of several hormones were measured in citrus under conditions of continuous flooding following a time-course design.

Operando Raman Spectroscopy Reveals Backpressure‐Controlled Dynamics in Diluted CO2 Electrolysis

open access: yesAdvanced Science, EarlyView.
High backpressure operation governs the CO2 reduction reaction (eCO2RR) kinetics and selectivity, as well as the CO2 and water dynamics, as revealed through operando Raman spectroelectrochemical measurement. Operating eCO2RR near diffusion‐limited conditions provides a platform for investigating the competition between eCO2RR and the hydrogen evolution
