Wall conditions in WEST during operations with a new ITER grade, actively cooled divertor

Nuclear Materials and Energy
Future fusion reactors like ITER and DEMO will have all-tungsten (W) walls and long pulses. These features will make wall conditioning more difficult than in most of the existing devices.

Far‐Infrared Hyperbolic Phonon–Polaritons in Zirconium Disulfide

Advanced Materials, EarlyView.
An unpatterned ZrS2${\rm ZrS}_2$ flake, coupled to far‐field infrared light by metal nanoribbons, reveals hyperbolic phonon polaritons with multiple higher‐order branches and effective refractive indices up to 223. This resonator‐assisted approach establishes ZrS2${\rm ZrS}_2$ as a compact van der Waals platform for deeply subwavelength far‐infrared ...

Boron beats nitrogen: strained boron–boron bonds as (molecular) proton sponges

Physical Chemistry Chemical Physics
The basicity and the hydrogen bond (HB) acceptor capability of diborane derivatives of dipyrazole 1 with a B–B bond have been studied theoretically using M06-2x and CCSD(T) methods. The proton affinities of 1b reach 1096 kJ mol −1 .

CVD Grown Hybrid MoSe2–WSe2 Lateral/Vertical Heterostructures With Strong Interlayer Exciton Emission

Advanced Materials, EarlyView.
A scalable bottom‐up CVD methodology, based on liquid transition metal salt precursors, is presented for the controlled growth of two high‐quality MoSe2–WSe2 heterostructures (HSs): purely lateral (HS I) and hybrid lateral/vertical (HS II), by simply adjusting precursor concentration.

Boron layer preparation, characterization and hydrogen isotope permeability for fusion application

Nuclear Materials and Energy
Due to the re-baseline of the fusion device ITER and the strategical decision to change from Be to W as first wall material, a boronization procedure has to be implemented into the wall conditioning phase.

True Closed‐Loop Recyclable Hydrogels Enabled by Imine Boronic Ester Crosslinking

Advanced Materials, EarlyView.
Subtle molecular differences in imine boronic ester crosslinkers profoundly influence hydrogel properties. 2‐formylphenylboronic acid crosslinkers form previously undisclosed 3‐amino‐benzoxaborole heterocycles, enhancing elasticity despite lower crosslinking density compared to their 4‐formylphenylboronic acid counterparts.

A Wireless, Passive Multimodal Wearable Sensor With Decoupled Sensing Capabilities

Advanced Materials, EarlyView.
A wireless passive multimodal electronic skin is presented for the simultaneous perception of pressure, humidity, and odor through a frequency‐divided LC resonator array. The decoupled sensing architecture suppresses cross‐interference and enables independent signal readout under superimposed stimuli while maintaining high stability.
