Sewage sludge proves to be difficult to dewater due to its composition and biological nature, and it is unsuitable for disposal with high moisture content. In the present work, sewage sludge is dewatered by the thermal compression, which shows unique separation advantages of various materials, and the effects of applied temperature and pressure on the dewatering performance are investigated. Th...

Results of an experimental and theoretical investigation of heat and moisture movement in unsaturated MX-80 bentonite are presented. A thermo-hydraulic cell that allows measurement of transient temperatures and facilitates the determination of pseudo-transients of moisture content, dry density and chemical composition has been used to perform thermal gradient tests. Results of a number of tests...

Although highly valuable as an R&D tool, ALD is a rather slow and thus expensive fabrication method for growing fi lms on the order of 1 μm thick, posing a challenge to industrial scaleup. Hence, there is a need to transfer learnings from ALD to higher-throughput manufacturing techniques without compromising quality. We fi rst demonstrate the ease of phase purifi cation of commercial SnS powder...

Van der Waals dielectrics, such as hexagonal boron nitride, are widely used to preserve the intrinsic properties of two-dimensional semiconductors in electronic devices. However, fabricating these materials on wafer scale and integrating them with is challenging because their synthesis typically requires mechanical exfoliation or vapour deposition processes. Here we show that a high-κ van diele...

In this article, curvature effects on elastic thermal buckling of double-walled carbon nanotubes under axially compressed force are investigated using cylindrical shell model. Also, the small scale effect is taken into account in the formulation. The dependence of the interlayer van der Waals (vdW) pressure on the change of the curvatures of the inner and outer tubes at that point is considered...

This paper is concerned with analysis for the strengthening effect of carbon fiber-reinforced polymer (CFRP) on steel columns under cyclic lateral loading in thermal environment. Based on the finite element theory of thermo-elastic problem and steel structure stability theory, the hysteretic behavior of axial compression steel columns was studied by using Ansys software. The main variables inve...
