Highly Efficient Antimicrobial Ceramics Based on Electrically Charged Interfaces

Authors: Reinosa, JJ; Rojo, MM; del Campo, A; Martin-Gonzalez, M; Fernandez, JF Article. ACS Appl. Mater. Interfaces. vol: 11. page: 1944-8244. Date: oct-23. 2019. Doi: 10.1021/acsami.9b10690. Abstract: The increasing threat of multidrug-resistant microorganisms is a cause of worldwide concern. This motivates a necessity to discover new antimicrobial agents or new mechanisms for microorganism eradication, different from

Engineering a Full Gamut of Structural Colors in All-Dielectric Mesoporous Network Metamaterials

Authors: Ruiz-Clavijo, A; Tsurimaki, Y; Caballero-Calero, O; Ni, G; Chen, G; Boriskina, SV; Martin-Gonzalez, M Article. ACS Photonics. vol: 5. page: 2330-4022. Date: JUN. 2018. Doi: 10.1021/acsphotonics.7b01569. Abstract: Structural colors are a result of the scattering of certain frequencies of the incident light on micro- or nanoscale features in a material. This is a quite different

Three-Dimensional Bi2Te3 Networks of Interconnected Nanowires: Synthesis and Optimization

Authors: Ruiz-Clavijo, A; Caballero-Calero, O; Martin-Gonzalez, M Article. Nanomaterials. vol: 8. page: 2079-4991. Date: MAY. 2018. Doi: 10.3390/nano8050345. Abstract: Self-standing Bi2Te3 networks of interconnected nanowires were fabricated in three-dimensional porous anodic alumina templates (3D-AAO) with a porous structure spreading in all three spatial dimensions. Pulsed electrodeposition parameters were optimized to grow highly oriented Bi2Te3 interconnected nanowires
