Recent Progress in the Phase‐Controlled Synthesis of Ruthenium Nanocrystals for Catalytic Applications

Advanced Materials, EarlyView.
Template effect and kinetic control enable crystal‐phase engineering of Ru nanocrystals, granting access to either metastable fcc‐Ru or stable hcp‐Ru with distinct surface structures, thermal stabilities, and catalytic behaviors. Moreover, the hcp‐Ru can further serve as an epitaxial template to direct Pd and Rh nanocrystals into the metastable hcp ...

State of the Art of Fuel Cells for Ship Applications [PDF]

, 2012
Fuel cells promise to be far more efficient, produce lower or zero emissions, and operate cleaner than conventional internal-combustion engine and gas turbine. They are already used for transportation application (buses, cars and tramways).

Alternative Fuel Cycle Strategies For Nuclear Power Generation In The 21st Century

, 2005
Revision 1The deployment of fuel recycling through either CONFU (COmbined Non-Fertile and UO[subscript 2] fuel) thermal water-cooled reactors (LWRs) or fast ABR (Actinide Burner Reactor) reactors is compared to the Once-Through LWR reactor system in ...

Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Nuclear fuels

, 2008
Le combustible est l'un des éléments essentiels d'un réacteur nucléaire. En son sein ont lieu les réactions nucléaires de fission des atomes lourds, uranium et plutonium. Il est au cœur du réacteur, mais également au cœur du système nucléaire dans son ensemble.

FUEL PERFORMANCE ANALYSIS OF EXTENDED OPERATING CYCLES IN EXISTING LWRs

, 1998
An integral part of a technical analysis of a core design, fuel performance is especially important for extended operating cycles since the consequences of failed fuel are greater for this operating strategy than for current practice. This stems mainly

Gold‐Stabilized Copper Enables Anodic Hydrogen Evolution for Ultralow‐Voltage CO‐to‐Ethylene Electrolysis

Advanced Materials, EarlyView.
Gold‐stabilized copper suppresses hydroxide‐driven deactivation during anodic hydrogen evolution from furfural. Pairing this low‐potential anode with CO‐to‐ethylene electroreduction enables sub‐1 V operation at 400 mA cm−2, high single‐pass CO conversion, and co‐production of ethylene, furoic acid, and a separate hydrogen stream.

Analysis of Variance for Item Differences in Verification Data with Unknown Groups

Science and Technology of Nuclear Installations, 2019
For sequentially collected data, this paper introduces a lag-one differencing method to estimate the random error standard deviation δR and then uses the estimate δ^R to calculate a change detection threshold in a moving window method to detect shifts in
