Role of lithium in enhancing radiation tolerance under γ-irradiation in lithium borosilicate waste glasses [PDF]

open access: yes
Lithium-containing borosilicate glasses are used for the safe containment of high-level nuclear waste in the UK. Glasses were fabricated with varying Li2O contents and irradiated to a total γ-dose of 80 MGy to probe the relationship between Li2O contents

Nonstoichiometric Defect Engineering in Mn2+‐Doped MgGa2O4 Persistent Phosphors Toward Enhanced Luminescence and Multimodal Optical Manometry

open access: yesAdvanced Science, EarlyView.
Mg2+ deficiency transforms Mn2+‐doped MgGa2O4 into a multifunctional persistent phosphor, enhancing green emission, thermal stability, and afterglow effect for optical anti‐counterfeiting. Under compression, spectral shifts enable visual pressure sensing with a sensitivity of 5.01 nm GPa−1 over a pressure range up to 30 GPa.

Orbital and Electrical Dual Function of Polymer Intercalant for Promoting NH4+ Storage in Vanadium Oxide Anode

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
The impact of polyaniline insertion on the atomic orbitals and electronic structure of vanadium oxide anode is systematically investigated for the first time. The electrode exhibits an outstanding capacity and unprecedent long‐term cycling life, owing to the electron transition to the V 3dxy state and the enhanced diffusion kinetics.

Coupled experiment/simulation approach for the design of radiation-hardened rare-earth doped optical fibers and amplifiers [PDF]

open access: yes, 2011
We developed an approach to design radiation-hardened rare earth -doped fibers and amplifiers. This methodology combines testing experiments on these devices with particle swarm optimization (PSO) calculations.

Simultaneous Electronic and Crystallographic Modulation of Cs3Bi2Br9 by Single‐Element Sn Substitution for Enhanced CO2 Photoreduction

open access: yesAdvanced Energy Materials, EarlyView.
Aliovalent B‐site substitution with Sn2+ in lead‐free perovskite, Cs3Bi2Br9, is employed to simultaneously induce lattice contraction and bromine vacancy through charge imbalance and ionic radius mismatch. The resulting structural distortion modulates the electronic structure and improves charge separation, leading to enhanced visible‐light‐driven CO2 ...

Defect-Induced Circularly Polarized Luminescence of Chiral Perovskite Films

open access: yes, 2023
Defect-induced strategy is employed to prepare green emission chiral perovskite films (GECP films) with circular polarized luminescence (CPL) via spin-coating a mixture of S/R-MBAPbBr3 chiral perovskite and methylamine bromide (MABr).

Characterizing Biopolymer Electrolytes in Zinc–Air Batteries: Challenges, Best Practices, and a Robust Workflow Guiding Future Research Paths

open access: yesAdvanced Energy Materials, EarlyView.
Bio‐based gel polymer electrolytes promise sustainable, mechanically adaptable zinc–air batteries, yet their progress is constrained by inconsistent characterization. This review critically links formulation, structure, interfaces, and cell performance, identifies methodological gaps under alkaline operating conditions, and proposes application ...
