Hevea brasiliensis seeds: A novel sustainable feedstock for ethanol production

open access: yesVietnam Journal of Chemistry, EarlyView.
Abstract The rubber tree (Hevea brasiliensis) is cultivated on a large scale mainly for the extraction of latex in Brazil and Southeast Asia, also generating large quantities of seeds. These seeds currently do not have large‐scale applications and may thus be considered as a residue.

Empirical Physics‐Based Normal Behavior Modeling of Drive Train Temperatures With High‐Resolution Wind Turbine Operating Data

open access: yesWind Energy, EarlyView.
ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one

Deterioration Law of Mechanical Properties of Insulation Pressboard Under Multifield Coupled Ageing

open access: yesHigh Voltage, EarlyView.
ABSTRACT Converter transformers can experience progressive deterioration of their oil–pressboard insulation under elevated temperature, combined AC–DC electrical stress and persistent mechanical vibration. This study investigates how mechanical vibration affects the mechanical properties of insulation pressboard and clarifies the associated microscopic
