Abstract Computational modelling of a centrifugal technique for separating binary mixtures thermoplastic polymers in the molten state is presented. The may be useful recycling polymeric materials. study investigates physical process component separation due to force batch process, showing potential using dispersed model describing complex mechanism underlying technique. Given long time scales c...

Bovine alpha-lactalbumin (BLA) is known to be present in molten globule form in its apo-state (i.e., Ca(2+) depleted state). We explored the organization and dynamics of the functionally important tryptophan residues of BLA in native, molten globule and denatured states utilizing the wavelength-selective fluorescence approach. We observed red edge excitation shift (REES) of 7 nm for the tryptop...

We investigate the dynamic thermal performance of a molten-salt packed-bed thermal energy storage (TES) system using capsules filled with high-temperature phase change material (PCM), which is identified as a promising low-cost TES system for concentrating solar power (CSP) plants. A transient twodimensional dispersion-concentric (D-C) model is modified to account for the phase change process w...

This paper gives an overview of thermal energy storage (TES) systems based on molten salts. It summarizes stateof-the-art molten salt TES systems. Storage systems in a research stage, such as the thermocline and floating barrier concepts, are also discussed. The paper summarizes previous work on molten salt material investigations at DLR. Experimental results of novel salt formulations with mel...

Metals cannot be extracted by electrolysis of transition-metal sulfides because as liquids they are semiconductors, which exhibit high levels of electronic conduction and metal dissolution. Herein by introduction of a distinct secondary electrolyte, we reveal a high-throughput electro-desulfurization process that directly converts semiconducting molten stibnite (Sb2S3) into pure (99.9%) liquid ...

In order to obtain the high-performance composites with high density, the influence of additional ultrasonic vibration on the infiltration of molten aluminum alloy (ASTM A336.0) into nickel porous preform by low-pressure and pressureless casting was investigated. There was no effect of ultrasonic vibration on infiltration distance under pressureless casting because of presence of surface oxide ...

The objective of the method was to prove the concept of a novel waste PCBs recycling process which uses inert, stable molten salts as the direct heat transfer fluid and, simultaneously, uses this molten salt to separate the metal products in either liquid (solder, zinc, tin, lead, etc.) or solid (copper, gold, steel, palladium, etc.) form at the operating temperatures of 450-470 °C. The PCB rec...
