Highly Sensitive Electrochemical Biosensor Based on Hairy Particles with Controllable High Enzyme Loading and Activity

open access: yesAdvanced Functional Materials, EarlyView.
For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,

Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

open access: yesAdvanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

Ultra‐High Temperature Molten Oxide Electrochemistry

Angewandte Chemie International Edition, 2022
AbstractRecently, the ultra‐high temperature electrochemistry (UTE, about >1000 °C) has emerged, which represents an exploration to extend the temperature limit of human technology in electrochemical engineering. UTE has far‐reaching impact on revolutionary low‐carbon metal extraction and the in situ production of oxygen for deep‐space exploration ...

High Temperature Superconducting Oxide Films

IEEE Transactions on Components, Hybrids, and Manufacturing Technology, 1988
The authors used sputter deposition with single oxide targets and metal molecular beam epitaxy to prepare thin films of the high-T/sub c/ oxide Y-Ba-Cu-O superconductor. The processing parameters, the structural characteristics, and the transport properties of the films are reported. The authors also discuss the microstructures of superconducting Y/sub

High Temperature Sealing of Silicon Oxide/Oxide Bonding Interfaces

ECS Meeting Abstracts, 2020
High temperature (>1000°C) annealing is necessary to completely close a bonding interface. Using interface synchrotron high energy X-ray reflectivity, we have investigated the sealing behavior of silicon thermal oxide/ silicon thermal oxide interfaces, with different surface roughnesses.

High temperature oxidation of Al4C3

Corrosion Science, 2020
Abstract Currently, high temperature corrosion resistant materials rely on the formation of an external surface oxide layer. This work is the first step in exploring an alternative coating concept in which one continuous phase in a two phase carbide–metallic binder coating system, preferentially oxidises internally within the composite.

High-Temperature Oxidation

2016
High-temperature oxidation (HTO) of metals and alloys is a scale-forming oxidation process in gaseous environments. HTO is influenced by metal temperature, gas composition, exposure time, and pressure, and it may be characterized by weight gain, thickness reduction (penetration), and rate of oxide thickness growth, which is a measure of the rate of ...
