As miniaturization of microelectronics reaches sub-10 nm scale, signal crosstalk and parasitic resistive-capacitive delay significantly limit device performance. While low dielectric constant (low-κ) dielectrics are widely recognized to address such issue, their poor thermal conductivity impedes heat management. Recently, scientists from Northwestern University Virginia demonstrated the fabrica...
Metal-organic frameworks (MOFs) refer to porous coordination materials that are formed from the assembly of metal ions and organic ligands. They have unique features, such as a large specific surface area, multiple active sites, easy functionalisation, adjustable biocompatibility. MOFs recently been widely used in field biomedical engineering owing their structures properties. This has enabled ...
Aqueous energy devices are under the spotlight of current research due to their safety, low cost and ease handling. Metal-organic frameworks (MOFs) derivatives have spurred extensive exploration as they provide a library new electrode materials. The rich structural flexibilities (such metal nodes, ligands, pore structure) endow MOFs MOFs-derivatives with vast opportunities for various devices. ...
This review summarizes the unique advantages and opportunities offered by mechanochemical process to generate MOF composites.
Abstract Herein, we report the synthesis of a nitrone‐linked covalent organic framework, COF‐115, by combining N , N′ ′′′‐(ethene‐1, 1, 2, 2‐tetrayltetrakis(benzene‐4, 1‐diyl))tetrakis(hydroxylamine) and terephthaladehyde via polycondensation reaction. The formation nitrone functionality was confirmed solid‐state 13 C multi cross‐polarization magic angle spinning NMR spectroscopy C‐isotope‐labe...
High conductivity and high level of electrolyte availability are the main requirements of active materials used in supercapacitors (SCs) to achieve high electrochemical efficiency. In recent years, metal-organic frameworks (MOFs) have been used as electrode materials for SCs due to their suitability of porosity and high surface area. However, using single-component MOFs in supercapacitors resul...
Manganese metal-organic framework (Mn-MOF) containing Mn2+ ions, benzenetricarboxylic acid (BTC) and N,N-dimethylformamid (DMF) was prepared and used as catalyst for oxidation of alkenes such as 1,1-diphenylethylene, trans-stilbene, cyclohexene, norbornene, styrene and cyclooctene to epoxides with 33-92% conversion and 75-100% selectivity and oxidation of alkanes such as fluorene, adamantane, e...
