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 ...
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 ...
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 ...
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 ...
Thermo-Catalytic Treatment of Vapors in the Recycling Process of Carbon Fiber-Poly (Benzoxazine) Composite Waste by Pyrolysis
(MDPI, 2018-11-06)
Recycling carbon fiber from residual carbon fiber reinforced plastics (CFRP) is one of the key aspects of the future in the field of waste management. This work presents the possibility of recovering chemical compounds ...
Fabrication of high-performance dual carbon Li-ion hybrid capacitor: mass balancing approach to improve the energy-power density and cycle life
(Nature, 2020-07-02)
Most lithium-ion capacitor (LIC) devices include graphite or non-porous hard carbon as negative electrode often failing when demanding high energy at high power densities. Herein, we introduce a new LIC formed by the ...
A Multi-Objective Approach for Anti-Osteosarcoma Cancer Agents Discovery through Drug Repurposing
(MDPI, 2020-11-22)
Osteosarcoma is the most common type of primary malignant bone tumor. Although nowadays 5-year survival rates can reach up to 60–70%, acute complications and late effects of osteosarcoma therapy are two of the limiting ...
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 ...
