Journal ArticleDOI
High-performance solid state supercapacitors assembling graphene interconnected networks in porous silicon electrode by electrochemical methods using 2,6-dihydroxynaphthalen
Cosmin Romanitan,Pericle Varasteanu,Iuliana Mihalache,Daniela C. Culita,Simona Somacescu,Razvan Pascu,Eugenia Tanasa,Sandra A. V. Eremia,Adina Boldeiu,Monica Simion,Antonio Radoi,Mihaela Kusko +11 more
TL;DR: The achievement of an easy scalable technology for solid state supercapacitors on silicon, with excellent electrochemical properties, is demonstrated, comparable to many of the best high-power and/or high-energy carbon-based super capacitors, their figures of merit matching under battery-like supercapACitor behaviour.
Journal ArticleDOI
Comparative analysis of honey and citrate stabilized gold nanoparticles: In vitro interaction with proteins and toxicity studies.
Adina Boldeiu,Monica Simion,Iuliana Mihalache,Antonio Radoi,Melania Banu,Pericle Varasteanu,Paul Nadejde,Eugeniu Vasile,Adriana Acasandrei,Roxana Cristina Popescu,Diana Savu,Mihaela Kusko +11 more
TL;DR: Results showed that honey mediated synthesis generates nanoparticles with reduced toxicity trends depending on the cell type, concentration of nanoparticles and exposure time toward various biomedical applications.
Journal ArticleDOI
Optimizing the Tin Selenide (SnSe) Allotrope/Gold-Based Surface Plasmon Resonance Sensors for Enhanced Sensitivity
TL;DR: In this paper, the authors investigated the potential improvement of the response of surface plasmon resonance (SPR) sensors by coating the gold layer with tin selenide monolayers.
Journal ArticleDOI
Unravelling the strain relaxation processes in silicon nanowire arrays by X‐ray diffraction
Cosmin Romanitan,Mihaela Kusko,Marian Popescu,Pericle Varasteanu,Antonio Radoi,Cristina Pachiu +5 more
TL;DR: In this paper, the shape of the pole figure in reciprocal space is ellipsoidal, which is the signature of lattice defects generated by the relaxation of the strain concentrated in the coalescence regions.
Journal ArticleDOI
Transition Metal Dichalcogenides/Gold-Based Surface Plasmon Resonance Sensors: Exploring the Geometrical and Material Parameters
TL;DR: In this article, the geometrical and material parameters of surface plasmon resonance (SPR) sensors were explored to gain insight about the mechanisms that control the sensors' response when different 2D materials monolayers (MoS2, MoSe2, WS2, WSe2) are used to modify the surface.
