Density Functional Theory Study on Mechanism of Mercury Removal by CeO₂ Modified Activated Carbon

Energies, 2018
Doping of CeO2 on activated carbon (AC) can promote its performance for mercury abatement in flue gas, while the Hg0 removal mechanism on the AC surface has been rarely reported.

Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

Advanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Comparison and excitation optimization of commercial quartz tuning forks for QEPAS

Frontiers in Physics
Quartz-enhanced photoacoustic spectroscopy (QEPAS) is a powerful technique for trace gas sensing, in which the quartz tuning fork (QTF) plays a key role in determining detection performance.

The influences of silane coupling agents on the heat and moisture resistance of basalt fibre‐reinforced composites

High Voltage, 2023
Basalt fibre composite materials have shown good application prospects in electrical equipment, but their reliability can be affected by damp‐heat ageing.

Generator Power Optimisation for a More-Electric Aircraft by Use of a Virtual Iron Bird [PDF]

, 2006
A prodedure is developed to minimise the generator design power within the electric power system of a future more-/ all-electric aircraft. This allows to save weight on the generators and on other equipment of the electic power system.

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres

Advanced Engineering Materials, EarlyView.
This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.

Application of Raman and Photoluminescence Spectroscopy to MgO‐C Refractories

Advanced Engineering Materials, EarlyView.
Visible to near infrared luminescence of MgO is studied on MgO‐C bricks and nominally pure MgO powder, with focus on two similar sharp high‐intensity signals, at 699 and 871 nm, each surrounded by symmetrical sidebands. The nature of these sidebands is investigated by temperature‐dependent spectroscopic measurements, confirming phonon involvement by ...
