Autor: Tanta Spataru, Simona Somacescu, Greta Patrinoiu, Adina Magdalena Musuc, Jose M. Calderon-Moreno, Oana Carp, Petre Ionita

Publikováno v: ChemSusChem. 14:2042-2049

Although both stable free organic radicals and biomass-derived hydrochars have emerged as appealing, green, multifunctional materials, their association has not been explored. In this study, strength is found to lie in their union, which primarily le

Multifunctional ZnO materials prepared by a versatile green carbohydrate-assisted combustion method for environmental remediation applications

Autor: Cristian D. Ene, Mariana Carmen Chifiriuc, Cornel Munteanu, Greta Patrinoiu, Ramona Ene, Oana Carp

Publikováno v: Ceramics International. 45:2295-2302

Nanosized ZnO has been prepared following a non-polluting, straightforward, and flexible combustion synthesis method, using as biofuels starch and cellulose, and as zinc source nitrate and acetate. While the crystallite size and the surface area of t

Spherical cobalt/cobalt oxide - Carbon composite anodes for enhanced lithium-ion storage

Autor: Vilas G. Pol, Valentin S. Teodorescu, Greta Patrinoiu, R. Birjega, Oana Carp, Jose M. Calderon-Moreno, Simona Somacescu, Vinodkumar Etacheri, Chulgi Nathan Hong, Dana C. Culita

Publikováno v: Electrochimica Acta. 264:191-202

Herein we report a simple and scalable route to synthesize porous cobalt/cobalt oxide - carbon sphere composites as anode material for rechargeable lithium-ion batteries. It involves the impregnation of starch-derived hydrochar spheres with a cobalt

Sustainable one-pot integration of ZnO nanoparticles into carbon spheres: manipulation of the morphological, optical and electrochemical properties

Autor: Jose M. Calderon-Moreno, Greta Patrinoiu, Adina Magdalena Musuc, Tanta Spataru, Oana Carp, Daniela C. Culita, R. Birjega, Simona Somacescu

Publikováno v: Physical Chemistry Chemical Physics. 18:30794-30807

ZnO-carbon composite spheres were synthesized via starch hydrothermal carbonization (HTC) in the presence of a soluble zinc salt (acetate), followed by thermal processing under an argon atmosphere. Besides sustainability, the one-pot procedure repres

Tunable ZnO spheres with high anti-biofilm and antibacterial activity via a simple green hydrothermal route

Autor: Greta Patrinoiu, Oana Carp, Carmen Chifiriuc, Crina Saviuc, R. Birjega, Jose M. Calderon-Moreno

Publikováno v: Journal of Colloid and Interface Science. 462:64-74

A family of distinct ZnO morphologies - hollow, compartmented, core-shell and full solid ZnO spheres, dispersed or interconnected - is obtained by a simple hydrothermal route, in the presence of the starch biopolymer. The zinc-carbonaceous precursors
