Organic Compounds

56.7K
All living things are formed mostly of carbon compounds called organic compounds. The category of organic compounds includes both natural and synthetic compounds that contain carbon. Although a single, precise definition has yet to be identified by the chemistry community, most agree that a defining trait of organic molecules is the presence of carbon as the principal element, bonded to hydrogen and other carbon atoms. However, some carbon-containing compounds such as carbonates, cyanides, and...

Intrinsically Disordered Proteins

19.2K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Volatilization01:10

Volatilization

5.7K
Volatilization gravimetry is an analytical technique that measures the mass lost due to the volatilization of the substance. This technique is used to estimate the amount of volatile material in a sample. To perform this method, heat a known amount of the sample to a high temperature in a crucible or other suitable vessel. The volatile substance in the sample evaporates, and the vapor is completely expelled from the crucible either by heating the sample or bubbling a stream of inert gas through...

Porosity and Absorption of Aggregate01:20

Porosity and Absorption of Aggregate

758
Aggregates contain pores of varying sizes; while some are completely enclosed within the particles, others open onto the surface, allowing water to penetrate. The porosity of aggregates is a major factor contributing to the overall porosity of concrete, given that aggregates constitute about three-quarters of concrete's volume.
When all pores in an aggregate are filled with water, the aggregate is considered saturated and surface-dry. If left in dry air, water will evaporate until the...

Porosity in Cement Paste01:18

Porosity in Cement Paste

434
The porosity of concrete is a measure of the void spaces within its structure. These spaces impact its strength and durability significantly. When water and cement interact, a chemical reaction called hydration creates a semi-solid paste. This paste includes combined water, making up approximately 23% of the cement's dry mass, and gel water, which fills minuscule voids known as gel pores, accounting for about 28% of the cement gel volume.
The balance of water to cement in the mix is...

Area of Science:

  • Materials Science
  • Nanotechnology
  • Chemistry

Background:

  • Two-dimensional metal-organic frameworks (2D MOFs) are emerging materials with potential applications in sensing.
  • Conventional 2D MOFs often lose porosity upon exfoliation to the monolayer regime, limiting their utility.
  • Developing MOFs with preserved porosity and responsive properties is crucial for advanced applications.

Purpose of the Study:

  • To report a novel 2D metal-organic framework (MOF) with intrinsic in-plane porosity.
  • To demonstrate the material's reversible colorimetric response to volatile organic compounds (VOCs).
  • To investigate the preservation of porosity after exfoliation into nanosheets.

Main Methods:

  • Synthesis of a unique 2D metal-organic framework (MOF).
  • Characterization of the MOF's structure and porosity.
  • Exposure of the MOF to various volatile organic compounds (VOCs) to observe color changes.
  • Exfoliation of the 2D MOF into nanosheets and assessment of porosity retention.

Main Results:

  • An uncommon 2D MOF with intrinsic in-plane porosity was successfully synthesized.
  • The 2D MOF exhibited a distinct and reversible color change upon exposure to different VOCs.
  • Porosity was maintained even after exfoliation into micron-scale lateral dimension nanosheets.
  • This overcomes the typical porosity loss associated with monolayer 2D materials.

Conclusions:

  • The developed 2D MOF offers a stable and responsive platform for chemical sensing.
  • The material's ability to retain porosity in nanosheet form opens new avenues for 2D MOF applications.
  • This work redefines the potential of channelled nanosheets derived from 2D MOFs.
