The role of shear flow collapse and enhanced turbulence spreading in edge cooling approaching the density limit

open access: yesNuclear Fusion
Experimental studies of the dynamics of shear flow and turbulence spreading at the edge of tokamak plasmas are reported. Scans of line-averaged density and plasma current are carried out while approaching the Greenwald density limit on the J-TEXT tokamak.

3D Nanoprinted Structures Promote Robust Integration of Brain Organoids into Topography‐Guided Neuronal Networks

open access: yesSmall, EarlyView.
Dedicated cultivation platforms facilitate the implementation of brain organoids in guided neuronal networks. Fabrication is enabled by two‐photon polymerization‐based 3D nanoprinting (3DN) and allows for cultivation in standard 12‐well plates. Fine features, namely slopes, funnels, rods, steps, and walls, facilitate and promote organoid positioning ...

Influences of Cleanliness, Carbide Size, Hardness, and Residual Stresses on Long‐Life Fatigue Strength and Crack‐Initiation Mechanisms in Carbide‐Rich Cold‐Work Tool Steels Using Normalized S–N Curves and Database‐Driven Validation of Murakami's √Area Model

open access: yessteel research international, EarlyView.
Rotating‐bending fatigue tests on AISI D2 and AISI A11 quantify how cleanliness, carbide structure, hardness, and fabrication‐induced compressive residual stresses govern long‐life fatigue at NG = 107 cycles. Statistical fracture‐surface analysis and extreme‐value √area statistics link crack‐initiators to LLF strength.

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

open access: yesVIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Nanomedicine applications in lymphoma: Advancing precision diagnostics, targeted therapeutics, and prospective developments

open access: yesVIEW, EarlyView.
Lymphoma is a group of blood cancers that can appear in lymph nodes, blood, bone marrow, spleen, liver, or the central nervous system, which makes drug delivery and disease monitoring difficult. This review summarizes how nanomedicine technologies may improve targeted treatment and imaging, while carefully separating approved or guideline‐supported ...

The nonlinear effects in the ionospheric plasma generated by strong thunderstorms seen by DEMETER satellite

open access: yesArchives of Mechanics
The terrestrial ionosphere is mainly a plasma region which is very sensitive to different disturbances. A wide range of plasma instabilities can develop in this region, which are often nonlinear processes and leading to the development of plasma ...

Large‐Scale Applications of Plasma Technologies: Progresses and Challenges

open access: yesHigh Voltage, EarlyView.
ABSTRACT Plasma technologies convert electrical power into energetic electrons, ions, reactive species, radiation and heat, thereby breaking through the bottleneck of purely thermal or chemical routes and bringing impressive changes to our world. This roadmap reviews the progress and challenges of plasma technologies from a large‐scale and application ...

Constrictions and shear stress are key determinants of amyloidogenic light chain (AL) amyloidosis

open access: yesThe FEBS Journal, EarlyView.
In this study, we investigate how flow constrictions and shear stress trigger cardiac antibody light chain (AL) fibril formation and deposition. We mimic the mechanical forces exerted by the heart and the microvasculature network using a mini‐peristaltic pump setup and a grid‐type microchannel network, respectively.

Maximizing the ion temperature in an electron heated plasma: from WEST towards larger devices

open access: yesNuclear Fusion
In electron heated plasmas, as the power increases, it is experimentally reported that the ion temperature ( T _i ) saturates while the electron temperature ( T _e ) increases [Beurskens NF 2022].
