ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.An α‐Al2O3‐decorated multilayer graphene membrane enables highly selective lithium ion extraction from artificial seawater via electrodialysis. The confined ion channels and competitive ion transport dynamics enhance lithium selectivity, achieving 88.9% purity and 88.6% recovery over three extraction cycles while maintaining stable ion flux.

Reprogrammable All‐Photonic Molecular Logic With Ln3+ Luminescent Hybrids in Solid State
Laser &Photonics Reviews, EarlyView.Mario P. de‐Saralegui et al. report an Eu3⁺/Tb3⁺‐doped organic–inorganic hybrid material that enables multiple reprogrammable logic operations using only physical stimuli. Additionally, this solid‐state, all‐photonic platform represents the first example in the literature performing reversible Feynman logic operations, marking a major step toward ...

Equivalence of two contour prescriptions in superstring perturbation theory
Journal of High Energy Physics, 2017 Conventional superstring perturbation theory based on the world-sheet approach gives divergent results for the S-matrix whenever the total center of mass energy of the incoming particles exceeds the threshold of production of any final state consistent ...

Integrated correlators in N $$ \mathcal{N} $$ = 4 super Yang-Mills and periods
Journal of High Energy Physics, 2022 We study perturbative aspects of recently proposed integrated four-point correlators in N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills with all classical gauge groups using standard Feynman diagram computations.

physica status solidi (b), EarlyView.Vacancies in low‐dose ion‐implanted GaN are studied by positron annihilation. Depth profiles of the net donor concentration (ND) are close to those for implanted impurities, but ND is 2–3 times higher than concentrations of implanted ions. The origin of donor‐like defects is expected to be N‐vacancy‐related defects, and Ga‐vacancy‐type defects play a ...

physica status solidi (b), EarlyView.The response of graphene and MoS2 monolayers to highly‐charged impinging ions is investigated using nonequilibrium Green functions theory. Electronic correlations are found to have a significantly stronger influence on the ultrafast ion‐induced electron dynamics in MoS2 than in graphene.
