Coupling polaritons in near-field radiative heat transfer between multilayer graphene/vacuum/α-MoO/vacuum heterostructures.

Both materials and structures can significantly affect radiative heat transfer, which is more pronounced in the near-field regime of two-dimensional and hyperbolic materials, and has promising prospects in thermophotovoltaics, radiative cooling, and nanoscale metrology. Hence, it is important to investigate the near-field radiative heat transfer (NFRHT) in complicated heterostructures consisting of two-dimensional and hyperbolic materials. Recent studies have reported that adding vacuum layers to multilayer structures can effectively enhance the NFRHT.

Thermal Insulation Performance of SiC-Doped Silica Aerogels under Large Temperature and Air Pressure Differences.

Silica aerogel composite is an excellent thermal insulator for spacecraft under high-temperature and complex air environments. This study intends to evaluate SiC-doped silica aerogel’s thermal insulation performance under large temperature and air pressure differences. In this paper, the hot surface’s temperature response of SiC-doped silica aerogel with different content was studied at significant temperature differences (ΔT) when pressure changes instantaneously.

Enhancing the flow field in parallel spiral-flow column photobioreactor to improve CO fixation with Spirulina sp.

A parallel spiral-flow column photobioreactor (PSCP) composed of eight spiral-flow columns, and two pipe headers was designed for scale-up cultivation of microalgae to capture CO. To solve the disturbance of spiral flow fields among parallel columns, computational fluid dynamics (CFD) simulation was used to optimize the main structural parameters, such as the number and the height of microalgae solution outlet (MSO), to improve flow field structure and enhance the cells' light/dark cycle. The horizontal velocity in the direction of optical path and the turbulent kinetic energy (TKE) reached the peak values of 0.

[ANTERIOR APPROACH DEBRIDEMENT AND BONE GRAFTING WITH SELF-LOCKED TITANIUM PLATE INTERNAL FIXATION FOR TREATING LUMBOSACRAL TUBERCULOSIS].

Objective: To explore the effectiveness of stage I anterior approach debridement and autologous iliac crest graft with single self-locked titanium plate internal fixation for the treatment of lumbosacral tuberculosis.

Methods: Seven cases of lumbosacral tuberculosis were treated by stage I anterior approach debridement, autologous iliac crest graft, and single self-locked titanium plate internal fixation between February 2010 and October 2014. There were 5 males and 2 females, aged 18-65 years (mean, 41.
