α‐Al2O3 Networks on MLG Membranes for Continuous Lithium Ion Extraction from Artificial Sea Water with Enhanced Selectivity and Durability

open access: yesENERGY &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.

Root‐Applied Phyto‐Courier Loaded With Rutin Translocates to Aerial Tissues Inducing Molecular and Anatomical Changes in Cannabis sativa Under Salinity

open access: yesNano Select, EarlyView.
The rutin‐loaded phyto‐courier formulation was taken up by hemp roots and translocated to aerial organs, inducing changes in the metabolome and gene expression. Under salt stress, the formulation preserved the leaf palisade layer and promoted the development of bast fibers in the stems.

Relational Bundle Geometric Formulation of Non‐Relativistic Quantum Mechanics

open access: yesFortschritte der Physik, EarlyView.
Abstract A bundle geometric formulation of non‐relativistic many‐particles Quantum Mechanics is presented. A wave function is seen to be a C$\mathbb {C}$‐valued cocyclic tensorial 0‐form on configuration space‐time seen as a principal bundle, while the Schrödinger equation flows from its covariant derivative, with the action functional supplying a ...

Untangling the Mechanisms in Magneto‐Electrocatalytic Oxygen Evolution

open access: yesSmall, EarlyView.
Magnetic fields can enhance the oxygen evolution reaction in electrocatalytic water‐splitting for green‐H2. Yet, commercialization cannot be realized until the underlying magneto‐electric mechanisms are understood. This work uses reactor orientation to untangle these mechanisms. Lorentz force is shown to control metallic plates, while spin‐polarization

Integral representation of the Feynman propagators of the Dirac fermions on the de Sitter expanding universe

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
The propagators of the Dirac fermions on the expanding portion of the $$(1+3)$$ (1+3) -dimensional de Sitter spacetime are considered as mode sums in momentum representation with a fixed vacuum of Bunch–Davies type.

Biotechnical Multiscale Engineering of Scaffolds for Stem Cell and Organoid Research

open access: yesSmall, EarlyView.
Biotechnical multiscale engineering consideration of geometric and structural parameters, which is called biotechnical multiscale engineering, has an influence on stem cell development and organogenesis comparable to that of molecular genetics and biochemical parameters.

Chemically Anchored PbS‐2PACz CQDs Inks for Scalable HTL in Narrow‐Bandgap and All‐Perovskite Tandem Solar Cells

open access: yesSmall, EarlyView.
PbS‐2PACz colloidal‐quantum‐dot ink, prepared via solution‐phase ligand exchange, forms conformal and defect‐suppressing interlayers. Subsequent treatment with a [2‐(9H‐carbazol‐9‐yl)ethyl]phosphonic acid (2PACz) solution yields a saturated PbS‐2PACz film with enhanced 2PACz coverage on the PbS surface.

Considerations on some algebraic properties of Feynman integrals [PDF]

open access: yesSurveys in Mathematics and its Applications, 2008
Some algebraic properties of integralsover configuration spaces are investigated in order to better understandquantization and the Connes-Kreimer algebraic approach to renormalization.
