Toughening β‐Ga2O3 via Mechanically Seeded Dislocations

Advanced Functional Materials, EarlyView.
β‐Ga2O3 is promising for next‐generation semiconductors but its brittleness limits flexible and high‐precision applications. Here, mechanically seeded dislocations introduced by surface deformation improved damage tolerance in (001) β‐Ga2O3. Nanoindentation and characterization show dislocations suppress cleavage cracks by enabling stable plastic ...

Enrichment of impurities seeded for exhaust control in a spherical tokamak power plant geometry

Nuclear Fusion
Through SOLPS-ITER simulations, we have investigated the ability of seeded argon and neon impurities to effectively control divertor power loading in a power-plant-class spherical tokamak geometry.

Impact of seeded plasma impurities on D retention in RAFM steels

Nuclear Materials and Energy, 2020
The effect of He seeding (He+ ion fraction, cHe+, of ~5 and ~10%) to D plasma (ion flux ~ 1.5–2 × 1021 m−2s−1, sample temperature ~ 373 K, and incident ion energy ~ 100 eV) on D retention in various reduced-activation ferritic/martensitic (RAFM) steels ...

Study on divertor detachment and pedestal characteristics in the DIII-D upper closed divertor

Nuclear Fusion, 2023
Experiments performed in DIII-D demonstrate that higher plasma current and heating power combined with impurity seeding facilitate the achievement of divertor detachment with a higher pedestal pressure and higher plasma performance in H-mode plasmas with

Prospective isolation of human bone marrow stromal cell subsets: a comparative study between Stro-1-, CD146- and CD105-enriched populations

, 2014
Stro-1 has proved an efficacious marker for enrichment of skeletal stem and progenitor cells although isolated populations remain heterogeneous, exhibiting variable colony-forming efficiency and osteogenic differentiation potential. The emerging findings

Suspended liquid particle disturbance on laser-induced blast wave and low density distribution [PDF]

, 2017
The impurity effect of suspended liquid particles on the laser-induced gas breakdown was experimentally investigated in quiescent gas. The focus of this study is the investigation of the influence of the impurities on the shock wave structure as well as ...

Impurity transport studies in ASDEX by means of neon-seeded pellets [PDF]

Nuclear Fusion, 1989
Neon-seeded deuterium pellets, containing 1% neon, were successfully produced and injected into ASDEX divertor discharges. The behaviour of the deposited neon ions was studied by VUV spectroscopy, using a special version of the ASDEX/JET impurity transport code for interpretation.

Role of Histidine‐Containing Peptoids in Accelerating the Kinetics of Calcite Growth

Advanced Functional Materials, EarlyView.
Amphiphilic histidine‐containing peptoids mimic carbonic anhydrase (CA) to accelerate calcite step growth. In the presence of Zn2+, they promote the deprotonation of HCO3−, the desolvation of Ca2+, and the reorganization of interfacial hydration layers, thereby reducing the activation barrier for calcite growth.

Non-linear magnetotransport in microwave-illuminated two-dimensional electron systems

, 2008
We study magnetoresistivity oscillations in a high-mobility two-dimensional electron system subject to both microwave and dc electric fields. First, we observe that the oscillation amplitude is a periodic function of the inverse magnetic field and is ...

Silver Ion‐Mediated [hk1]‐Oriented Sb2Se3 Crystal Growth for Efficient Photoelectrochemical Hydrogen Evolution

Advanced Functional Materials, EarlyView.
Ag+‐mediated hydrothermal crystal engineering promotes preferential [hk1]‐oriented growth of Sb2Se3 via an ultrathin MoOx interlayer, improving crystallinity and suppressing non‐radiative recombination. The optimized Ag+ treatment photocathode delivers 24.7 mA cm−2 at 0 VRHE and improved stability, revealing an ion‐modulated route to high‐performance ...
