[{"abstract":[{"text":"A series of four oligomers of cyclopentadithiophene-vinylenes end capped with pyridine groups was prepared and their optical and electronic properties studied. Treatment with trifluoroacetic acid (TFA) leads to the bisprotonation of the nitrogens of the pyridine, which has an important impact on the optical properties. Excess treatment with TFA provokes the oxidation of the conjugated core, generating radical cations and dications. The ease of the TFA treatment in solution was extended to protonation in the solid-state where further characterization of the neutral and TFA-treated samples was carried out in electrically active substrates in organic field-effect transistors. Finally, the new molecules were found to be excellent conductors in single-molecule junctions thanks to strong electron delocalization and resonance orbital mediated transport. These studies show the opening of a spectrum of possibilities by suitable terminal substitution of π-cores.","lang":"eng"}],"publication":"RSC Advances","date_created":"2024-09-09T07:14:34Z","publication_identifier":{"issn":["2046-2069"]},"license":"https://creativecommons.org/licenses/by-nc/3.0/","type":"journal_article","DOAJ_listed":"1","date_updated":"2024-12-10T10:38:07Z","article_type":"original","OA_place":"publisher","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Synthesis and electronic properties of pyridine end-capped cyclopentadithiophene-vinylene oligomers","OA_type":"gold","status":"public","tmp":{"name":"Creative Commons Attribution-NonCommercial 3.0 Unported (CC BY-NC 3.0)","short":"CC BY-NC (3.0)","image":"/images/cc_by_nc.png","legal_code_url":"https://creativecommons.org/licenses/by-nc/3.0/legalcode"},"citation":{"mla":"Guijarro, Fernando G., et al. “Synthesis and Electronic Properties of Pyridine End-Capped Cyclopentadithiophene-Vinylene Oligomers.” <i>RSC Advances</i>, vol. 10, no. 68, Royal Society of Chemistry, 2020, pp. 41264–71, doi:<a href=\"https://doi.org/10.1039/d0ra08220a\">10.1039/d0ra08220a</a>.","short":"F.G.

We report the magnetic and magnetothermal properties of gadolinium silicide (Gd5Si4) nanoparticles prepared by surfactant-assisted ball milling of arc melted bulk ingots of the compound. Using different milling times and speeds, a wide range of crystallite sizes (13–43 nm) could be produced and a reduction in Curie temperature (TC) from 340 K to 317 K was achieved, making these nanoparticles suitable for self-controlled magnetic hyperthermia applications. The magnetothermal effect was measured in applied AC magnetic fields of amplitude 164–239 Oe and frequencies 163–519 kHz. All particles showed magnetic heating with a strong dependence of the specific absorption rate (SAR) on the average crystallite size. The highest SAR of 3.7 W g−1 was measured for 43 nm sized nanoparticles of Gd5Si4. The high SAR and low TC, (within the therapeutic range for magnetothermal therapy) makes the Gd5Si4 behave like self-regulating heat switches that would be suitable for self-controlled magnetic hyperthermia applications after biocompatibility and cytotoxicity tests."}],"date_updated":"2024-10-15T13:44:01Z","type":"journal_article","DOAJ_listed":"1","OA_type":"gold","title":"Size-dependent magnetic and magnetothermal properties of gadolinium silicide nanoparticles","user_id":"0043cee0-e5fc-11ee-9736-f83bc23afbf0","OA_place":"publisher","article_type":"original","oa":1,"keyword":["General Chemistry","General Chemical Engineering"],"citation":{"mla":"Nauman, Muhammad, et al. “Size-Dependent Magnetic and Magnetothermal Properties of Gadolinium Silicide Nanoparticles.” <i>RSC Advances</i>, vol. 10, no. 47, Royal Society of Chemistry, 2020, pp. 28383–89, doi:<a href=\"https://doi.org/10.1039/d0ra05394e\">10.1039/d0ra05394e</a>.","chicago":"Nauman, Muhammad, Muhammad Hisham Alnasir, Muhammad Asif Hamayun, YiXu Wang, Michael Shatruk, and Sadia Manzoor. “Size-Dependent Magnetic and Magnetothermal Properties of Gadolinium Silicide Nanoparticles.” <i>RSC Advances</i>.

The investigation of spatial distribution of nanofillers via a non-distractive thermal pulse method illustrates that the surface functionalization of nanocubes plays a key role in the uniform distribution of charge polarization within the polymer matrix. The discharged energy density of the nanocomposite with 30 vol% BaTiO3 nanocubes is ∼44 × 10−3 J cm−3, which is almost six times higher than that of the neat polymer. The facile processing, along with the superior mechanical and electrical properties of the BaTiO3/PMMA–ABS nanocomposites make them suitable for implementation into capacitive electrical energy storage devices.","lang":"eng"}],"publication_identifier":{"issn":["2046-2069"]},"date_created":"2020-02-05T14:17:26Z","publication":"RSC Advances","author":[{"first_name":"Saman Salemizadeh","last_name":"Parizi","full_name":"Parizi, Saman Salemizadeh"},{"full_name":"Conley, Gavin","last_name":"Conley","first_name":"Gavin"},{"last_name":"Costanzo","id":"D93824F4-D9BA-11E9-BB12-F207E6697425","full_name":"Costanzo, Tommaso","first_name":"Tommaso","orcid":"0000-0001-9732-3815"},{"first_name":"Bob","last_name":"Howell","full_name":"Howell, Bob"},{"last_name":"Mellinger","full_name":"Mellinger, Axel","first_name":"Axel"},{"last_name":"Caruntu","full_name":"Caruntu, Gabriel","first_name":"Gabriel"}],"article_type":"original","extern":"1","_id":"7457","issue":"93","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Fabrication of barium titanate/acrylonitrile-butadiene styrene/poly(methyl methacrylate) nanocomposite films for hybrid ferroelectric capacitors","year":"2015","publisher":"RSC","status":"public","citation":{"ista":"Parizi SS, Conley G, Costanzo T, Howell B, Mellinger A, Caruntu G. 2015.
