In this context, both the high coordination number (CN) and large porosity of metal nodes are detrimental to the melting of MOFs. For the former, the highly coordinated metal node indicates the unease of bond dissociation19; while for the later, the large local space means the detached ...
Capillary sequencing using fluorophore-labeled primers is used to make the technique high-throughput15. UV irradiation at 254 nm induces cross-links between RNA and protein as nucleobase excitation at this wavelength leads to the formation of a covalent bond with a nearby amino acid side-chain16...
In this method, the sweep efficiency can be improved by continuously injecting large volumes of chemical that do not completely block the flow but instead increase the resistance. This can be done either by increasing the viscosity of the injectant or through the adsorption of the injectant which...
This requires both the presence of polar covalent bonds and a certain molecular geometry. Most covalent bonds between different atoms are polar, due to differing electronegativity values of the elements. Each polar covalent bond is i...
The process of attaching silanes onto functionalized surfaces is shown in Fig. 3. First, hydrolysis (1) takes place, cleaving off an ethyl residue. Thereafter, silane attaches to the hydroxylated surface (2) via hydrogen bonds. Finally, condensation (3) leads to a covalent bond, which links ...
What type of bond exists within the water molecule? A. polar covalent B. hydrogen bond C. ionic D. non-polar covalent Intra- and Intermolecular Bonding: Intramolecular bonding refers to the bonding happening within one molecule, such as covalent...
TiO2is an ecofriendly photocatalyst that absorbs light in the UV region. Hence, TiO2-incorporated polymer films efficiently absorb UV light. TiO2mediated photocatalysis involves the absorption of photons of suitable energy leading to the generation of electrons and holes which promote the formation of ...
The electrochemical method for hydrogen preparation involves the reversal of the above reactions during electrode discharge. Hydrogen atoms are released from the hydride phase or formed at the electrode surface through dissociative chemisorption of molecular hydrogen, and then undergo electrooxidative ...
This treatment is described as the formation of a covalent bond between some reactive constituents of LCFs and chemical reagents, with or without the use of a catalyst [7]. The integration of hydrophilic fibre and hydrophobic matrix induces fibre swelling within the matrix and weakens bonding ...
