Uniform Spheres of α-NaYF4:RE3+ (RE=Eu, Tb, Ce, Er, and Tm): Template-Free Synthesis, Multi-Color Photoluminescence, and Their Application in Cellular Imaging

open access: yesCrystals, 2020
Uniformly dispersed luminescent probes with a high brightness and high resolution are desired in bio imaging fields. Here, ~100 nm sized and well-dispersed spheres of RE3+ doped α-NaYF4 (rare earth (RE) = Eu, Tb, Ce, Er, and Tm) have been facile ...

Antibacterial metals and alloys for potential biomedical implants

open access: yesBioactive Materials, 2021
Metals and alloys, including stainless steel, titanium and its alloys, cobalt alloys, and other metals and alloys have been widely used clinically as implant materials, but implant-related infection or inflammation is still one of the main causes of ...

Anisotropy

open access: yesDefinitions, 2020
The pattern of motion of test bodies in space-time described by the anisotropic Kasner solution is studied. Distances and velocities are determined by the methods used in astronomical observations.

(INVITED)Laser-driven white light with tunable low-colour temperature based on novel ZrO2-doped (Gd,Lu)2O3:Eu red-emitting transparent ceramics

open access: yesOptical Materials: X, 2022
Novel red-emitting ZrO2-doped (Gd,Lu)2O3:Eu transparent fluorescent ceramics were fabricated via a vacuum sintering method. The f–f transitions of Eu3+ in the ZrO2-doped (Gd,Lu)2O3:Eu transparent fluorescent ceramics have much higher intensity than the ...

Achieving outstanding heat-resistant properties in Mg alloy via constructing stable solute-network

open access: yesMaterials Research Letters, 2023
A new Mg–Sm–Ce–Mn-based alloying system with a large miscibility gap was uncovered, and multi-solute co-segregations at high-angular grain boundaries (HAGBs), dislocations and low-angular grain boundaries (LAGBs) are obtained after the proper extrusion ...

Magnetic Anisotropy at Nanoscale [PDF]

open access: yesJournal of Nanotechnology, 2011
Nanoscale objects often behave differently than their “normal-sized” counterparts. Sometimes it is enough to be small in just one direction to exhibit unusual features. One example of such a phenomenon is a very specific in-plane magnetic anisotropy observed sometimes in very thin layers of various materials.
