Semi-clathrate hydrate slurry as a cold energy storage and transport medium: Rheological study, energy analysis and enhancement by amino acid November 2022 Energy 264:126226
Basics of rheology. Rheology is used to describe and assess the deformation and flow behavior of materials. Fluids flow at different speeds and solids can be deformed to a certain extent. Oil, honey, shampoo, hand cream, toothpaste, sweet jelly, plastic materials, wood, and metals – depending on their physical behavior, they can be put in an ...

To …
5. Conclusions. MR elastomers are barely investigated for mechanical to magnetic/electrical energy conversion. In this work, we investigated both the MR effect (dependence of mechanical properties on a magnetic field) and the pseudo-Villari effect (dependence of magnetic field on mechanical strain). Anisotropic and isotropic magneto-rheological ...
Rheology ( / riːˈɒlədʒi /; from Greek ῥέω (rhéō) ''flow'', and -λoγία (-logia) ''study of'') is the study of the flow of matter, primarily in a fluid ( liquid or gas) state but also as "soft solids " or solids under conditions in which they respond with plastic flow rather than deforming elastically in response to an applied force. [1]

High temperature storage tests were used to evaluate the storage stability of PMA. Samples were poured into a cigar tube (2.5 cm diameters and 14 cm heights), vertically placed in an air-circulating oven, at 163 ± 1 °C for 48 h. After which the tube was taken out from the oven and stored in a refrigerator for 4 h. Once cooled, the tube then ...
Tetra-n-butylammonium bromide (TBAB) semi-clathrate hydrate is an attractive phase change material for cold energy storage and transport. The high viscosity of hydrate slurry is a major challenge for process design and causes large pumping power consumption, not to mention the significant discrepancy of viscosity data observed in the literature.
MXene for metal–ion batteries (MIBs) Since some firms began selling metal–ion batteries, they have attracted a lot of attention as the most advanced component of electrochemical energy storage systems, particularly batteries. Anode, cathode, separator, and electrolyte are the four main components of a standard MIB.
