piRNA - Piwi-interacting RNAs

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...

MicroRNAs01:22

MicroRNAs

21.0K
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...

Catenins01:23

Catenins

2.2K
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...

Mnemonic Devices

Mnemonic devices are cognitive tools that facilitate memory retention by linking new information to familiar patterns or organizational strategies. These techniques are beneficial for remembering complex or lengthy sets of information by simplifying and structuring them in easily retrievable ways.
Acronyms
Acronyms are created by using the initial letters of a series of words to form a new word or phrase. This approach condenses complex information into a single, memorable entity. For example,...

siRNA - Small Interfering RNAs

16.3K
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...

Area of Science:

  • Materials Science
  • Nanotechnology
  • Ceramics Engineering

Background:

  • MXenes, a class of 2D transition metal carbides, nitrides, and carbonitrides, possess unique properties like nanometer thickness and hydrophilic surfaces.
  • Their potential applications span advanced ceramics and composites, necessitating investigation into their role as additives.
  • Ultra-high-temperature ceramics (UHTCs), such as zirconium diboride (ZrB2), require enhanced properties for extreme environment applications.

Purpose of the Study:

  • To investigate the effect of titanium carbide MXene (Ti3C2Tx) as an additive in zirconium diboride (ZrB2) UHTCs.
  • To evaluate the influence of MXene on the densification, microstructure, and mechanical performance of ZrB2.
  • To explore MXenes as sintering aids and reinforcement agents for UHTCs.

Main Methods:

  • Synthesis of homogeneous green bodies of Ti3C2Tx and ZrB2 via electrostatic self-assembly in aqueous media.
  • Densification of the ceramic composites using field-assisted (spark plasma) sintering.
  • Characterization of relative density, oxygen content, microstructure (core-shell formation, dislocations), hardness, Young's modulus, and flexural strength.

Main Results:

  • Incorporation of 0.5 wt.% MXene enhanced ZrB2 relative density from ~89% to ~96%.
  • MXene addition reduced oxygen content in ZrB2 from ~5 at.% to ~2-3 at.% at 2.5 wt.% loading.
  • Significant mechanical improvements observed: 36% increase in hardness, ~12% in Young's modulus, and ~15% in flexural strength at 2.5 wt.% MXene.

Conclusions:

  • Titanium carbide MXene (Ti3C2Tx) acts as an effective sintering aid for ZrB2 UHTCs, promoting higher densification.
  • MXene addition leads to the formation of a beneficial core-shell microstructure and enhances mechanical properties.
  • MXenes show significant potential as reinforcement agents for developing advanced UHTCs for demanding applications.
