Alloying Cu, Fe, and Co in Ni/YSZ Electrodes for High‐Temperature CO2 Electrolysis: Impact on TPB Density, Activity, and Carbon Deposition Resistance

open access: yesCarbon Energy, EarlyView.
Systematic alloying of Ni with Cu, Fe, and Co in Ni/YSZ electrodes modifies active site density up to 43%, decreases activation energies by up to 44%, and reduces carbon deposition fourfold. Cu–Ni alloy is among the most promising alloy catalysts for electrochemical CO2 reduction in SOECs.

Synthesis of Single‐Crystalline Ni‐Rich Cathodes for Lithium‐Ion Batteries With Superior High‐Voltage Stability by Mo/Nb Dual Doping

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel synthesis method of single‐crystalline LiNi0.8Co0.15Al0.05O2 (NCA) is introduced, involving the stripping of grain boundaries from polycrystalline NCA (PC‐NCA) during Mo/Nb co‐doping. Mo doping near the grain surface significantly reduces parasitic interface reactions and inhibits the excessive growth of CEI films, while Nb doping within the ...

Support‐Driven Hydrogen Migration Enhances Ammonia Decomposition in Direct Ammonia Protonic Ceramic Fuel Cells

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Enhanced hydrogen species migration enabled by FN/BZY catalyst mitigates intermediate accumulation and improves DA‐PCFC performance during ammonia decomposition. Ammonia, with its high hydrogen density and carbon‐free nature, serves as ideal fuel for direct ammonia protonic ceramic fuel cells (DA‐PCFCs).

The Inner-Core Size Increase of Typhoon Megi (2010) During its Rapid Intensification Phase

open access: yesTropical Cyclone Research and Review, 2013
: While Typhoon Megi (2010) shared many common features of tropical cyclones (TCs) that crossed Luzon Island in northern Philippines, it experienced a significant inner-core size increase with little eyewall contraction during its rapid intensification ...

An easy-to-implement and efficient data assimilation method for the identification of the initial condition: the Back and Forth Nudging (BFN) algorithm [PDF]

open access: yes, 2008
International audienceThis paper deals with a new data assimilation algorithm called the Back and Forth Nudging. The standard nudging technique consists in adding to the model equations a relaxation term, which is supposed to force the model to the ...

Wonder as a Gateway to Science Meaning‐Making: Primary Pupils’ Narrative Journeys

open access: yesFuture in Educational Research, EarlyView.
ABSTRACT This study explores how wonder fosters transformative learning in science education for pupils (11–12 years old), creating meaning about cycles in nature. As an emotional and epistemic trigger, wonder may bridge everyday experiences with abstract scientific concepts by stimulating curiosity and creativity. Through a narrative writing task, the

Effect of Prudential Policies on Sovereign Bond Markets: Evidence From the ASEAN‐4 Countries

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT This paper examines the effects of prudential policies on the sovereign vulnerability of ASEAN‐4 countries. We measure sovereign vulnerability within the network connectedness of sovereign bonds between ASEAN‐4 countries (Indonesia, Malaysia, the Philippines and Thailand) and six other countries (the US, the UK, the European Union, China ...
