Flat-shaped carbon-graphene microcomposites as electrodes for high energy supercapacitors
(Royal Society of Chemistry, 2019-06-28)Herein, we report a simple approach for the preparation of phosphate-functionalized carbonaceous graphene-based composites. The homogeneous deposition of a thin layer of phenolic resin on the surface of graphene oxide (GO) ... -
Graphene as Vehicle for Ultrafast Lithium Ion Capacitor Development Based on Recycled Olive Pit Derived Carbons
(Electrochemical Society, 2019-08-21)Herein we report a series of lithium ion capacitors (LICs) with extraordinary energy-to-power ratios based on olive pit recycled carbons and supported on graphene as a conducting matrix. LICs typically present limited ... -
Graphene-coffee waste derived carbon composites as electrodes for optimized lithium ion capacitors Author links open overlay panel
(Pergamon-Elsevier, 2020-06)Herein we report an easy, ecofriendly and cheap synthetic approach for the preparation of carbon composites from the pyrolysis and activation of coffee waste and graphene oxide, and their evaluation as potential electrodes ... -
Nd3+-Doped Lanthanum Oxychloride Nanocrystals as Nanothermometers
(American Chemical Society, 2021-09-16)The development of optical nanothermometers operating in the near-infrared (NIR) is of high relevance toward temperature measurements in biological systems. We propose herein the use of Nd3+-doped lanthanum oxychloride ... -
Phosphorus-Functionalized Graphene for Lithium-Ion Capacitors with Improved Power and Cyclability
(Wiley, 2021-03)Herein, we report an easy approach for the preparation of graphene-based materials suitable as electrodes for lithium-ion capacitors (LICs). To the best of our knowledge, this is the first time that phosphorus-functionalized ... -
Slot-Die Process of a Sol–Gel Photocatalytic Porous Coating for Large-Area Fabrication of Functional Architectural Glass
(MDPI, 2021-06-06)The slot-die process is an appealing technology for the fabrication of coatings on large-area substrates. However, its application on the production of photocatalytic coatings based on sol–gel formulations remains virtually ... -
Towards a High-Power Si@graphite Anode for Lithium Ion Batteries through a Wet Ball Milling Process
(MDPI, 2020-05-27)Silicon-based anodes are extensively studied as an alternative to graphite for lithium ion batteries. However, silicon particles suffer larges changes in their volume (about 280%) during cycling, which lead to particles ... -
Understanding enhanced charge storage of phosphorus-functionalized graphene in aqueous acidic electrolytes
(Elsevier, 2020-11-20)The mechanisms behind enhanced charge storage of P-functionalized carbons are unraveled for the first time using non-porous graphene oxide treated with phosphoric acid and annealed at either 400 or 800 degrees C. The ... -
UV-Selective Optically Transparent Zn(O,S)-Based Solar Cells
(Wiley, 2020-11)This work reports experimental evidence of a photovoltaic effect in transparent UV-selective Zn(O,S)-based heterojunctions. Zn(O,S) has a strong interest for the development of UV-selective solar cells with high transparency ...
