Dependence of divertor turbulence on plasma density and current in TCV

open access: yesNuclear Fusion
To reliably predict the distribution of heat and particle fluxes at the target plates of tokamaks, a comprehensive understanding of turbulence throughout the entire Scrape-Off-Layer (SOL) is imperative.

Neutral pressure and separatrix density related models for seed impurity divertor radiation in ASDEX Upgrade

open access: yesNuclear Materials and Energy, 2019
Analytical expressions for the divertor radiation around the onset of detachment based on the divertor neutral pressure and the upstream separatrix density are tested against measurements on strongly nitrogen seeded high confinement mode (H-mode ...

Resilient Calvarial Bone Marrow Supports Retinal Repair in Type 2 Diabetes

open access: yesAdvanced Science, EarlyView.
Skull bone (calvarium) marrow in diabetic mice stay structurally intact and keeps making blood cells, unlike the bone marrow of the leg bones. The skull marrow is exposed to cerebrospinal fluid (CSF), which contains protective molecules called oxysterols.

WEST full tungsten operation with an ITER grade divertor

open access: yesNuclear Fusion
The mission of WEST (tungsten-W Environment in Steady-state Tokamak) is to explore long pulse operation in a full tungsten (W) environment for preparing next-step fusion devices (ITER and DEMO) with a focus on testing the ITER actively cooled W divertor ...

Systematic Metabolic Engineering and Model‐Guided Optimization for High‐Level Production of L‐Theanine From Xylose in Escherichia Coli

open access: yesAdvanced Science, EarlyView.
This study is pioneering in constructing the shortest known synthetic pathway for L‐theanine production from xylose within E coli. Through comprehensive metabolic engineering strategies, our engineered strain achieved the highest reported L‐theanine titer from xylose, with a titer of 95.42 g/L, and a yield of 0.55 g/g.

Lattice Carbon‐Mediated Ultralow‐Barrier C–C Coupling for Selective CO Electroreduction to Ethylene

open access: yesAdvanced Science, EarlyView.
Combined DFT and molecular dynamics simulations reveal that while the lattice carbon at the MXene edge cannot directly bind CO2 to form ethylene, it acts as an active center to promote C─C coupling between adjacent *CO intermediates for ethylene production.

Combining Electrochemical Reduction with Biosynthesis for Directed Conversion of CO2 into a Library of C3 Chemicals

open access: yesAdvanced Science, EarlyView.
In the H‐type electrolytic cell, carbon dioxide is reduced to acetic acid via electro‐microbial catalysis. The simply processed acetic acid is further converted through biological fermentation into high‐value‐added products, including acrylic acid, L‐lactic acid, and β‐alanine.

Spatial Control Over Tether‐Tunable Coordination on Palladium for Divergent Synthesis of Bicyclo[n.1.0]alkanes via Oxidative Cyclopropanation of Enynes

open access: yesAdvanced Science, EarlyView.
We have developed a Pd‐catalyzed oxidative cyclopropanation of 1,n‐enynes employing cyclic diacyl peroxides as bifunctional reagents that serve as both tether‐tunable oxidants and spatially controlled dicarboxylate anions. ABSTRACT Bicyclo[n.1.0]alkanes are highly valuable scaffolds in drug discovery and synthetic chemistry.

Orbital Hybridization‐Mediated Decoupling of Electrocatalytic Functions for Paired CO2 Electrosynthesis

open access: yesAdvanced Science, EarlyView.
This study constructs a dual‐scale Ag‐based catalyst on CeO2 nanorods via a facet‐guided strategy. This catalyst can induce a cascaded orbital hybridization effect, which synergistically optimizes oxygen vacancy stability, CO desorption kinetics, and charge transfer efficiency.
