Applying medicinal chemistry strategies to understand odorant discrimination [PDF]

open access: yes, 2016
Associating an odorant’s chemical structure with its percept is a long-standing challenge. One hindrance may come from the adoption of the organic chemistry scheme of molecular description and classification.

Strain Release Chemistry of Photogenerated Small‐Ring Intermediates [PDF]

open access: yesChemistry – A European Journal, 2021
AbstractPhotochemical processes, such as isomerizations and cycloadditions, have proven to be very useful in the construction of highly strained molecular frameworks. Photoinduced ring strain enables subsequent exergonic reactions which do not require the input of additional chemical energy and provides a variety of attractive synthetic options leading

The pyrolytic decomposition of metal alkoxides (di-acetoxy-di-t-butoxy-silane, DADBS) during chemical vapour deposition of thin oxide films [PDF]

open access: yes, 1993
In this study the effects of the nature of metal alkoxides on their vapour pressures and thermal decomposition chemistry are reported. The vapour pressure and the volatility of a metal alkoxide strongly depends on the steric effect of its alkoxy group ...

Reaction Chemistry Of Epoxides With Fluorinated Carboxylic Acids [PDF]

open access: yes, 2021
During measurements designed to develop a chiral tag rotational spectroscopy methodology for establishing the absolute configuration of a known persistent fluorinated carboxylic acid pollutant (FRD-903), an interesting reaction chemistry was observed. In

Organic molecules in the protoplanetary disk of DG Tau revealed by ALMA [PDF]

open access: yes, 2019
Planets form in protoplanetary disks and inherit their chemical compositions. It is thus crucial to map the distribution and investigate the formation of simple organics, such as formaldehyde and methanol, in protoplanetary disks.

Assessing the Effect of Stabilization and Carbonization Temperatures on Electrochemical Performance of Electrospun Carbon Nanofibers from Polyacrylonitrile

open access: yesAdvanced Energy & Sustainability Research, 2023
Supercapacitors (SCs) are considered a promising alternative to batteries to power up portable and wearable devices. Among different categories of materials for SCs, carbon nanofibers (CNFs) are particularly appealing for their electrochemical ...

Investigation of supramolecular architectures of bent-shaped pyridine derivatives: from a three-ring crystalline compound towards five-ring mesogens [PDF]

open access: yesNew J. Chem. 40, 6977-6985 (2016), 2016
In searching for novel photoactive liquid crystals, we have synthesized a series of five-ring pyridine-based bent-core compounds bearing different substituents at the peripheral phenyl rings (CH3O, Cl and NO2). Their mesomorphic behaviour has been investigated by polarizing optical microscopy, differential scanning calorimetry and X-ray scattering, and

Synthetic and theoretical studies of novel ring closure and ring opening reactions [PDF]

open access: yes, 2006
Ring closure and ring opening reactions are in many cases useful synthetic procedures in organic chemistry. They allow the preparation of complex molecules with high stereoselectivity and good yields. Mechanistic and theoretical studies have been carried

Particle-particle and quasiparticle random phase approximations: Connections to coupled cluster theory [PDF]

open access: yes, 2013
We establish a formal connection between the particle-particle (pp) random phase approximation (RPA) and the ladder channel of the coupled cluster doubles (CCD) equations.
