Photoswitchable Norbornadiene-Quadricyclane Interconversion Mediated by Covalently Linked C60. [PDF]
Chemistry, 2020 Switching! The synthesis of several norbornadiene (NBD)–fullerene adducts is herein reported. Within these new hybrid systems, the photochemical isomerization of NBD is combined with the electron affinity of C60. This enables the selective light‐induced isomerization of the NBD derivative to its corresponding quadricyclane (QC) counterpart and the back

Agricultural and Forest Entomology, Volume 25, Issue 4, Page 622-636, November 2023., 2023 Abstract Cerambyx welensii Küster (Coleoptera: Cerambycidae) is a wood‐borer responsible for the decline of Mediterranean oaks in open woodlands. To establish that contact pheromones are involved in mate recognition of C. welensii, we extracted the cuticular hydrocarbons by solid phase microextraction at pre‐reproductive, beginning and ending of the ...

Seal materials in flexible plastic food packaging: A review
Packaging Technology and Science, Volume 36, Issue 7, Page 507-532, July 2023., 2023 This review on heat seal materials aims to give a literature overview to optimize the material selection in flexible food packaging and obtain seals with desired tightness and strength. The simplified representation of temperature dependence of hot tack and seal strengths of thermoplastic films shows low values below seal initiation temperature (A ...

European Journal of Organic Chemistry, Volume 2022, Issue 33, September 6, 2022., 2022 An efficient Lewis acid‐assisted asymmetric carbonyl‐ene reaction to set the 1α‐hydroxyl functionality of enol‐triflate, precursor of the A‐ring of the hormone calcitriol and its 1α‐hydroxyderivatives, is described. Abstract The secondary parallel hypercalcemic effects associated with the treatment of several hyperproliferative diseases with the ...

Small, Volume 18, Issue 30, July 27, 2022., 2022 Solution‐based methods are reviewed for the preparation of representative, multifunctional noncentrosymmetric oxide nanocrystals with perovskite and nonperovskite crystalline structures. Elucidation of the reaction pathways and crystallization mechanisms is a prerequisite for improving their resulting morphology in the future and aggregation state for ...

European Journal of Organic Chemistry, Volume 2022, Issue 16, April 27, 2022., 2022 The preparation of enantiomerically pure cis‐C‐glycosyl compounds, through a long‐range epimerization at C5 of readily accessible d‐ or l‐carbohydrates, by means of a remote reductive radical sequence was described. A comparative study of the radical process promoted by a tin reagent or with photoredox conditions was also performed.

Thermodynamics of thallium alkanoates I. Heat capacity and thermodynamic functions of thallium(I) n-hexanoate [PDF]
The Journal of Chemical Thermodynamics, 1985 Abstract The sub-ambient heat capacity of thallium(I) n-hexanoate is characterized by transitions at 203.5 and 208.3 K which show C p, m R maxima of about 400 and 2500 and ( ΔS m R )' s of 1.03 and 1.07. Both appear to be essentially first order and show typical under-cooling phenomena.
