Thermal Conductive Network Construction and Enhanced Thermal Conductivity in Mica Tape Composites for Large Generators by Pre‐Placed h‐BN@PDA‐Modified Mica Paper

open access: yesHigh Voltage, EarlyView.
ABSTRACT The lower thermal conductivity (TC) of mica tape hinders the evolution of large generators towards higher voltage and capacity. To enhance the TC of the mica tape, with the help of the three‐dimensional (3D) multi‐layer framework of the mica paper, a 3D polydopamine‐coated boron nitride (h‐BN@PDA) TC network was constructed by pre‐placing h‐BN@

The Diverse Behaviours of Discharged Degradation at Varied Interfaces of Silicone Gel/Ceramic Substrates Under High‐Frequency Square Wave Voltage

open access: yesHigh Voltage, EarlyView.
ABSTRACT Because of the harsh serving conditions of insulated gate bipolar transistor (IGBT) packaged by silicone gel with high voltage and high frequency, it is crucial to reveal the developing characteristics and inhibiting method of discharged degradation at the interface of silicone gel/ceramic substrates.

Visual Function Assessment in Geographic Atrophy: A Review

open access: yesClinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Geographic atrophy (GA) causes significant vision impairment and reduction in vision‐related quality of life. Fundus autofluorescence (FAF) is the gold standard of structural assessment of GA but is a surrogate marker for vision loss, which can be assessed by tests of visual function and functional vision.

Smart selective navigator (SSN): enhancing urban winter road maintenance through optimized arc routing with hard turn restrictions

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract This paper introduces a novel heuristic method, the smart selective navigator (SSN), for addressing arc routing problems (ARPs) with a focus on integrating hard turn restrictions in urban winter operations. Addressing a significant gap in existing ARP methodologies, SSN seamlessly incorporates common side constraints, such as vehicle ...

Thin film sputter-deposition of AlN crystals in oxygenated chamber: a pilot study

open access: yesMaterials Research Express
Aluminium nitride (AIN) is a promising thin film electrical insulation material layer in electronic devices. The magnetron sputtering method is usually employed to sputter-deposit AlN thin film on silicon (Si) substrate using a pure aluminium (Al ...
