Green Synthesis and Flexibilization Engineering of (ECMP)2MnBr4 for Smart Textile‐Integrated Luminescence

Advanced Science, Volume 12, Issue 42, November 13, 2025.
Green‐synthesized (ECMP)2MnBr4 achieves near‐unity photoluminescence quantum yield (98.97%) and triple‐mode emission (photo/X‐ray/mechano), enabling wearable anti‐counterfeiting textiles, ultrasensitive X‐ray imaging (15.62 nGyair s−1), and demonstrating potential for optical stress sensing.

Narrow-based gait in people with Parkinson's disease: Its mechanisms explored

Journal of Parkinson’s Disease
Background People with Parkinson's disease (PD) typically exhibit a narrow-based gait. We previously found that walking with reduced trunk rotation and obliquity led to narrow-based gait in healthy adults; a decrease in trunk motion coincided with a ...

The Margin of Stability During a Single-Turn Pirouette in Female Amateur Dancers: A Pilot Study

Applied Sciences
Balance control in pirouettes has previously been characterized by constraint of the topple angle. However, there is a paucity of research using the margin of stability (MoS) as a dynamic measure of balance related to pirouettes.

EVALUATING MULTI-LAYERED SHIELDS FOR LOW ENERGY PHOTONS USING MCNP5 CODE AND XCOM PROGRAM

, 2019
MCNP5 was used to evaluate the shielding properties of different composite shields made of combinations of four elements; Tungsten (W), Bismuth (Bi), Tin (Sn), and Zinc (Zn), at different weight ratios. Attenuation coefficients calculated by MCNP5 were compared with XCOM theoretical data for 11 different photon energies ranging from (15 -150 keV). Mass

Photon and neutron shielding performance of boron phosphate glasses for diagnostic radiology facilities

Results in Physics, 2019
This study focuses on radiation shielding characteristics of Li2O, Al2O3 and ZnO-doped boron phosphate glasses containing PbO and Bi2O3. Mass attenuation coefficient (μ/ρ) values of the glasses have been calculated using MCNPX code at various photon ...

Ambulatory Estimation of XCoM using Pressure Insoles and IMUs

, 2018
Ambulatory gait assessment using minimal sensors has quite an impact for different applications requiring localised sensing. ForceShoes™ was developed as one such solution. It consists of two IMUs, and two 6DoF force and moment (F&M) sensors on each foot1. Additionally, an ultrasound system was added 2.

Mass attenuation coefficients, water and tissue equivalence properties of some tissues by Geant4, XCOM and experimental data

, 2022
The mass attenuation coefficients (pip) of some tissues such as muscle (ICRU-44), adipose (ICRP) and blood (Whole) and tissue equivalents such as soft tissue model (H63C6O28N) and water have been investigated using Geant4 simulation tool kit. Appreciable variations have been noted for mu/rho values by changing the photon energy for the studied tissues.
