Substrate-Specific Evolution of Amine Dehydrogenases for Accessing Structurally Diverse Enantiopure (R)-β-Amino Alcohols

The biocatalytic oxidative deamination of β-amino alcohols holds significant practical potential in kinetic resolution and/or deracemization process to access (R)-β-amino alcohols. This study exemplifies a notable instance of acquisition and utilization of this valuable oxidative deamination activity. Initially, the mutation N261M (M0) was...

Development of spectral-phenological features for deep learning to understand Spartina alterniflora invasion

Invasive Spartina alterniflora (S. alterniflora), a native riparian species in the U.S. Gulf of Mexico, has led to serious degradation to the ecosystem and biodiversity as well as economic losses since it was introduced to China in 1979. Although multi-temporal remote sensing offers unique capability to monitor S. alterniflora over large...

Performance assessment of a multi-fuel hybrid engine for future aircraft

This paper presents the performance assessment of a novel turbofan engine using two energy sources: Liquid Natural Gas (LNG) and kerosene, called Multi-Fuel Hybrid Engine (MFHE). The MFHE is a new engine concept consisting of several novel features, such as a contra-rotating fan to sustain distortion caused by boundary layer ingestion, a...

Equilibrium running principle analysis on an adaptive cycle engine

As an evolutional concept of variable cycle engine, the adaptive cycle engine draws widely attention with high expectations. It combines a variable geometry schedule and component matching principles to demonstrate its advantages such as avoiding severe inlet spillage drag and the wide variable cycle characteristics. Thus, this paper aims at...

Performance assessment of a Multi-fuel Hybrid Engine for Future Aircraft

This paper presents performance assessment of the proposed hybrid engine concept using Liquid Natural Gas (LNG) and kerosene. The multi-fuel hybrid engine is a new engine concept integrated with contra rotating fans, sequential dual combustion chambers to facilitate “Energy Mix” in aviation and a Cryogenic Bleed Air Cooling System (CBACS). The...

Modeling and Characteristics of a Novel Multi-fuel Hybrid Engine for Future Aircraft

Civil air transportation has undergone significant expansion over the past decades and is continuing to grow. Nevertheless, the tendency of energy depletion and the severe environmental problems yield challenges in its further development. To mitigate the climate impact of civil aviation, the Advisory Council for Aeronautics Research in Europe ...
