Summary
Titanium carbide (Ti3C2Tx) MXene additives significantly boost heat transfer fluid performance. This research shows enhanced critical heat flux and heat transfer coefficients for industrial applications.
Area of Science:
- Materials Science
- Nanotechnology
- Chemical Engineering
Background:
- Heat-exchanging fluids are crucial for industrial processes.
- Improving critical heat flux (CHF) and heat transfer coefficient (HTC) is vital for efficiency.
- MXenes offer novel properties for fluid enhancement.
Purpose of the Study:
- To investigate titanium carbide (Ti3C2Tx) MXene as an additive in heat-exchanging fluids.
- To evaluate the impact of MXene on boiling regime, CHF, and HTC.
- To determine optimal MXene concentration for stability and industrial application.
Main Methods:
- A low concentration (0.1 wt %) of Ti3C2Tx MXene was added to deionized water.
- Pool boiling experiments were conducted under atmospheric pressure.
- Rheological studies assessed MXene stability in the base fluid.
- Interfacial properties like surface roughness, wettability, and conductivity were analyzed.
Main Results:
- Ti3C2Tx MXene significantly increased CHF by 70.1% and HTC by 213.5% compared to pure deionized water.
- MXene dispersion showed superior performance over Ag/ZnO-enhanced fluids.
- Boiling regime shifted due to MXene flake circulation and stratification.
- Improved interfacial properties and fluid-surface interactions were observed.
Conclusions:
- Ti3C2Tx MXene is a highly effective additive for enhancing heat transfer fluids.
- The study demonstrates potential for large-scale industrial applications.
- MXene additives offer a promising route to improved energy efficiency in heat exchange systems.

6.7K
PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...

21.1K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

2.3K
Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. All catenins, except α-catenin, contain a characteristic protein sequence called the armadillo repeat and are therefore also called armadillo proteins.
Catenins in Cell Junctions
Catenins bind to cell adhesion molecules such as cadherins and link them to different cytoskeletal proteins depending on the type of cell junction. At the...

16.5K
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...
