Achieving Stable Paired Electrolysis of Captured CO2 and 5‐Hydroxymethylfurfural (HMF) via Tuning Anolyte Composition and Anode Surface

Advanced Functional Materials, EarlyView.
Highly stable paired electrolysis of CO2 and biomass‐derived alcohol (HMF) is achieved by replacing conventional alkaline electrolytes with a tailored triethylamine‐carbonate buffer and anion‐conducting ionomer coatings. This configuration effectively mitigates electrolyte degradation and pH instability typically encountered in alkaline CO2 ...

Conceptual design of a space nuclear fast reactor

Acta Polytechnica
This paper finds an improved combination of fuel, enrichment, and coolant for a fast reactor suitable for nuclear electric propulsion. The study simulates an infinite lattice considering two enrichments, with fuel options (ceramics and metal alloys), and

Reactores nucleares.

, 1961
Sabemos que existen unas partículas sin carga eléctrica, llamadas neutrones, que pueden penetrar en el núcleo de los átomos venciendo la barrera de potencial eléctrico que existe alrededor de dichos núcleos. Dichas partículas son capaces, en determinados casos, de romper, de dividir, el niicleo atómico con que chocan, en dos partes más o menos iguales,

Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

Advanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

Numerical simulation of long and slender cylinders vibrating in axial flow applied to the Myrrha reactor [PDF]

, 2012
Flow induced vibrations are an important concern in the design of nuclear reactors. One of the possible designs of the 4th generation nuclear reactors is a lead-cooled fast reactor of which MYYRHA is a prototype.

Additive‐Driven Phase Control for Stable and Efficient CsPbI₃ Solar Cells Via Ambient Low‐Temperature Processing

Advanced Functional Materials, EarlyView.
CsPbI₃ perovskite solar cells face stability issues due to high annealing temperatures and moisture. Butylammonium acetate (BAAc) enables stable phase formation at 160°C in ambient laboratory conditions, enhancing efficiency and stability, achieving 18.6% PCE, and maintaining over 81% efficiency after 1,000 hours of maximum power point tracking under 1

Enhancing Mechanical Deformability of Rigid Conjugated Polymers through Functional Additive‐Induced Persistence Length Modulation

Advanced Functional Materials, EarlyView.
This study demonstrates a molecular strategy to enhance the stretchability of conjugated polymers by incorporating plasticizing molecular additives (PMAs). PMAs reduce the persistence length and promote chain entanglement, enabling deformable thin films with preserved electrical performance. A systematic analysis combining rheology, neutron scattering,
