Machine Learning‐Assisted Inverse Design of Soft and Multifunctional Hybrid Liquid Metal Composites

open access: yesAdvanced Functional Materials, EarlyView.
A machine learning framework is presented for inverse design of synthesizable multifunctional composites containing both liquid metal and solid inclusions. By integrating physics‐based modeling, data‐driven prediction, and Bayesian optimization, the approach enables intelligent design of experiments to identify optimal compositions and realize these ...

Bismuth-based gap-plasmon metasurfaces for visible photonics with volatile tuning potential [PDF]

open access: yes, 2021
Gap-plasmon metasurfaces based on metal-insulator-metal (MIM) nanostructures have been extensively employed over the last years, as they provide a versatile design platform for local and/or global control of the amplitude, phase and polarisation of light

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Mineral Processing of Silver-carrying Bismuth Minerals from Yunnan

open access: yesKuangchan zonghe liyong
The gravity separation crude concentrate produced by a certain mine contains 17.9 g/t of silver, 1.15% of bismuth, and 23.42% of sulfur. 73.29% of the silver is present in bismuth minerals, with the main bismuth mineral being natural bismuth and a small ...

Quantifying Subsurface Weak in‐Plane Magnetization of Mixed Phase BiFeO3 by Scanning Nitrogen Vacancy Magnetometry

open access: yesAdvanced Functional Materials, EarlyView.
We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.

Extruded small-core bismuth oxide glass holey fibres [PDF]

open access: yes
We report our progress on the fabrication and characterisation of highly nonlinear bismuth oxide glass holey fibres. The measured losses for these fibres were ~3 dB/m at 1.55 µm, and the effective nonlinearity of the smallest core fibre was as high as ...

Preparation of bismuth-based microrods and their application in electroanalysis [PDF]

open access: yes, 2017
Bismuth-based microrods (BiMRs) were synthesized through a single reductant-controlled chemical reduction method. With the various quantity of reductant, different morphologies of Bi based materials were obtained. Characters of BiMRs were investigated by

Bismuth-containing drugs in clinical practice in the XXI century - history or a new round of possibilities?

open access: yesЛечащий Врач
Background. Bismuth is a somewhat rare element, similar in content to silver and mercury, but cheaper to produce because large amounts of bismuth are extracted as a by-product of copper and tin processing.

Long‐Range Coordination Environment Modulates Single‐Atom Local States and Systemic Impact on CO2 Photoconversion

open access: yesAdvanced Functional Materials, EarlyView.
Terminal groups on Cu porphyrins modulate the electronic states of single‐atom Cu centers through a long‐range electronic effect, without altering the Cu coordination geometry. Meanwhile, a multi‐descriptor framework is established that incorporates porphyrin regulation, hybrid catalyst properties, and CO2 photoreduction capabilities.

Unraveling the Electronic Structure of Silicon Vacancy Centers in 4H‐SiC

open access: yesAdvanced Functional Materials, EarlyView.
The electronic structure of the silicon vacancy in 4H‐SiC is probed via transient absorption spectroscopy, uncovering previously inaccessible excited states of the quartet and doublet spin channels, including the V2' transition. In combination with theoretical analysis, a comprehensive picture of the electronic structure is established.
