Summary
Researchers developed a novel method using UV/ozone and annealing to control silver nanowire fragmentation. This creates conductive paths for resistive switching in electronic devices.
Area of Science:
- Materials Science
- Nanotechnology
- Electronics
Background:
- Silver nanowire (Ag NW) networks are promising for electronic devices.
- Rayleigh instability causes nanowire fragmentation at high temperatures, hindering applications.
- Conventional fragmentation leads to insulating networks due to particle separation.
Purpose of the Study:
- To control Ag NW fragmentation for resistive switching applications.
- To develop a novel method combining UV/ozone irradiation and low-temperature annealing.
- To explore the new function of Ag NW networks in resistive switching.
Main Methods:
- Utilizing ultraviolet/ozone irradiation and low-temperature annealing.
- Designing a specific Ag/AgOx interface to control fragmentation.
- Investigating the morphology of fragmented Ag NWs.
Main Results:
- Achieved controlled fragmentation into short nanorod-like segments or nanoparticle chains.

Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

01:22Switching of BJT

Switching behavior in Bipolar Junction Transistors (BJTs) is a fundamental aspect utilized in various electronic circuits, particularly for digital logic applications like switches and amplifiers. In a typical switching circuit, a BJT alternates between cut-off and saturation modes, corresponding to the "off" and "on" states, respectively, thus behaving like an ideal switch.

4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

00:59Mass Spectrometry: Alkene Fragmentation
3.7K
Alkenes lose one electron from the unsaturated π bond upon ionization and form stable molecular ions. Further fragmentation of alkenes occurs through three different reaction pathways. The most prominent fragmentation is the cleavage at the allylic position. The resultant allylic carbocation is resonance stabilized. In the mass spectra of terminal alkenes, this fragment appears at a mass-to-charge ratio of 41. In the internal alkenes, where there are two choices of allylic cleavage, the...
