Towards analogue black hole merger

Comptes Rendus. Physique
We study the effects of the wavevector-dependent losses on polariton condensates. We demonstrate that because of these losses, a single vortex becomes a center of a convergent flow, which allows describing it by an analogue Kerr black hole metric with a ...

Measurement of reactive species absolute concentrations in N2, Ar/N2, He/N2 and H2/N2 microwave flowing afterglows at reduced pressure

, 2021
International audienceReduced pressure (2-20 Torr) flowing afterglows initiated in N2 and in mixtures of N2 with rare (Ar,He) or molecular (H2) gases generate and transport high concentrations of active species (atoms, metastable states, …) that can be ...

An Integrated Oxygen‐Supplying Device and Predictive Multiphysics Model for Extended Ambient Transport of Insulin‐Producing Cells

Advanced Functional Materials, EarlyView.
Cell therapies typically rely on cold‐chain logistics and cryopreservation, limiting access and compromising cell quality. Here, a dual‐chamber device separates an oxygen‐supplying chamber from a hyaluronic acid cargo chamber, sustaining oxygen delivery for over 70 h and enabling ambient‐temperature shipment.

Process screening in additive manufacturing: Detection of keyhole mode using surface topography and machine learning

Additive Manufacturing Letters
Screening of defective additive manufactured (AM) parts is crucial for ensuring process consistency and part reliability, yet common microstructural inspection methods can be time-consuming or destructive.

Adsorption selective carbon membrane the for separation of O2/N2 and C1-C4 Hydrocarbon/N2 [PDF]

, 2006
In this study, adsorption selective carbon membranes were developed using cellulose acetate as carbon precursor. The membranes were used for the separation of C1-C4 hydrocarbon and O2/N2.

−–N2 scattering

, 1994
We discuss in this note how the correlated static exchange potential changes with bond length for N2 molecule where the earlier extensive results at equilibrium exist. We have used many-body coupled cluster technique for this study.

Dimensionality‐Driven Interfacial Electronic Coupling in Carbon‐Supported Gd‐CuO Catalysts for Selective CO2 Electroreduction to Ethylene

Advanced Functional Materials, EarlyView.
The 2D carbon‐supported Gd–CuO exhibits strong interfacial electronic coupling, abundant oxygen vacancies, and highly exposed active sites, enabling efficient CO enrichment and C─C coupling toward selective and durable CO2‐to‐C2H4 conversion. ABSTRACT Copper‐based catalysts are promising for electrochemical CO2 reduction toward value‐added chemicals ...

ELECTROSTATIC (LANGMUIR) PROBE MEASUREMENTS IN RF DRIVEN He, N2, BCl3, AND BCl3/N2 PLASMAS [PDF]

, 2008
A Langmuir probe diagnostic system was developed to measure the electron density distribution in BCl3/N2 mixtures to determine if an average electron energy increase might be partially responsible for the previously observed etch rate enhancement of GaAs

N2 and P3 latency.

, 2013
N2 and P3 recorded for No-Go trials in AC and NAC. No difference was observed with N2. However, heavy drinkers displayed a delayed No-Go P3 in response to AC trials, while light drinkers did not.
