Defect Engineering in Biomedical Sciences

Advanced Materials, 2023
AbstractWith the promotion of nanochemistry research, large numbers of nanomaterials have been applied in vivo to produce desirable cytotoxic substances in response to endogenous or exogenous stimuli for achieving disease‐specific therapy. However, the performance of nanomaterials is a critical issue that is difficult to improve and optimize under ...

Defect‐Engineered Nanozyme‐Linked Receptors

Small, 2021
AbstractThough nanozymes are successfully applied in various areas, the increasing demands facilitate the exploitation of nanozymes possessing higher activity and more functions. Natural enzyme‐linked receptors (ELRs) are critical components for signal transductions in vivo by expressing activity variations after binding with ligands. Inspired by this,

Defect Engineering for SIMOX Processing

Solid State Phenomena, 2007
SIMOX (Separation-by-Implantation-of-Oxygen) is an established technique to fabricate silicon-on-insulator (SOI) structures by oxygen ion implantation into silicon. The main problem of SIMOX is the very high oxygen ion fluence and the related defects. It is demonstrated that vacancy defects promote and localize the oxide growth. The crucial point is to

Defect Engineering for Fuel‐Cell Electrocatalysts

Advanced Materials, 2020
AbstractThe commercialization of fuel cells, such as proton exchange membrane fuel cells and direct methanol/formic acid fuel cells, is hampered by their poor stability, high cost, fuel crossover, and the sluggish kinetics of platinum (Pt) and Pt‐based electrocatalysts for both the cathodic oxygen reduction reaction (ORR) and the anodic hydrogen ...

Defect Engineering

MRS Bulletin, 1991
The pervasive role of defects in determining the thermal, mechanical, electrical, optical, and magnetic properties of materials is biblical. Thermodynamic control of imperfection under equilibrium conditions dictates, for instance, the high temperatures needed to raise defect content for diffusion processes.

Defects and Aliovalent Doping Engineering in Electroceramics

Chemical Reviews, 2020
Since the positive influences of defects on the performance of electroceramics were discovered, investigations concerning on defects and aliovalent doping routes have grown rapidly in the fields of inorganic chemistry and condensed matter physics. In this article, we summarized the types of defects in electroceramics as well as characterization tools ...

Defect engineering of ZnO

Applied Surface Science, 2008
The defect responsible for the transparent to red color change of nominally undoped ZnO bulk single crystals is investigated. Upon annealing in the presence of metallic Zn as reported by Halliburton et al. and also Ti and Zr a native defect forms with an energy level about 0.7 eV below the conduction band.

Engineered Planar Defects Embedded in Opals

Advanced Materials, 2004
A method for the fabrication of engineered planar defects inside opals (see Figure) is presented. These defects act as photonic microcavities, introducing a localized state in the gap. The scalability of the defect allows for the tuning of the spectral position of the defect by changing the size of the defect relative to the periodicity of the lattice.
