Examination of the effects of porosity upon intensification of thermal storage of PCMs in a shell-and-tube type system

Case Studies in Thermal Engineering, 2022
This study examined the heat characteristics of a vertical shell-tube thermal storage system with phase change materials. A three-dimensional finite volume method involving an interface mesh was employed to reduce the computational time.

The influence of the volatiles on the slag composition for the heating process [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2020
The physicochemical properties of slag are of great importance in pyrometallurgy. If there is a volatile component in the slag, evaporation will inevitably occur.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Influence of Fin Geometry on Enhancement of Phase Change Material Melting in a Finned Double-Pipe Heat Exchanger

Energies
Low thermal conductivity of phase change materials (PCMs) remains a major limitation in the design of efficient thermal energy storage systems. Enhancing the thermal performance of PCM storage units is therefore a critical design consideration.

Properties and formation mechanism of rings during rotary kiln reduction of low-grade iron ore

工程科学学报, 2018
To ease the imbalance between the supply and demand for iron ore in the ferrous industry of China, a low-temperature reduction process via an ore-coal composite method was developed to recover iron from low-grade iron-ore resources (about 30%).
