Journal ArticleDOI
Hyperbolic Meta-Antennas Enable Full Control of Scattering and Absorption of Light
Nicolò Maccaferri,Yingqi Zhao,Tommi Isoniemi,Marzia Iarossi,Marzia Iarossi,Antonietta Parracino,Giuseppe Strangi,Giuseppe Strangi,Giuseppe Strangi,Francesco De Angelis +9 more
TL;DR: This work introduces a novel concept of hybrid metal-dielectric meta-antenna supporting type II hyperbolic dispersion, which enables full control of absorption and scattering of light in the visible/near-infrared spectral range and demonstrates that two main modes can be excited by direct coupling with the free-space radiation.
Journal ArticleDOI
Electron Energy Loss Spectroscopy of Bright and Dark Modes in Hyperbolic Metamaterial Nanostructures
Tommi Isoniemi,Tommi Isoniemi,Nicolò Maccaferri,Nicolò Maccaferri,Quentin M. Ramasse,Giuseppe Strangi,Giuseppe Strangi,Francesco De Angelis +7 more
TL;DR: In this article, the spatial distribution of plasmon polaritons in multilayered type II HMM nanostructures is acquired with an aloof electron beam adjacent to structures of current interest.
Journal ArticleDOI
Conjugation with carbon nanotubes improves the performance of mesoporous silicon as Li-ion battery anode
Timo Ikonen,Nathiya Kalidas,Katja Lahtinen,Tommi Isoniemi,Tommi Isoniemi,J. Jussi Toppari,Ester Vázquez,M. Antonia Herrero-Chamorro,José Luis García Fierro,Tanja Kallio,Vesa-Pekka Lehto +10 more
TL;DR: In this paper, thermally carbonized mesoporous silicon (TCPSi) microparticles and single-walled carbon nanotubes (CNTs) are conjugated to create a hybrid material that performs as the Li-ion battery anode better than the physical mixture of TCPSi and CNTs.
Journal ArticleDOI
Designer Bloch Plasmon Polariton Dispersion in Hyperbolic Meta-Gratings
Nicolò Maccaferri,Tommi Isoniemi,Michael Hinczewski,Marzia Iarossi,Giuseppe Strangi,Francesco De Angelis +5 more
TL;DR: In this paper, the mechanism of excitation of high-k Bloch-like Plasmon Polariton (BPPs) modes with ultrasmall modal volume using a meta-grating was investigated.
Journal ArticleDOI
Improved antifouling properties and selective biofunctionalization of stainless steel by employing heterobifunctional silane-polyethylene glycol overlayers and avidin-biotin technology
Ville Hynninen,Leena Vuori,Markku Hannula,Kosti Tapio,Kimmo Lahtonen,Tommi Isoniemi,Elina Lehtonen,M. Hirsimäki,J. Jussi Toppari,Mika Valden,Vesa P. Hytönen +10 more
TL;DR: A straightforward solution-based method to modify the biofunctionality of stainless steel (SS) using heterobifunctional silane-polyethylene glycol (silane-PEG) overlayers is reported, enabling the tailoring of SS to enhance its activity for biomedical and biotechnological applications.
