Electrochemical Rejuvenation of Anodically Coloring Electrochromic Nickel Oxide Thin Films
Huiying Qu,Huiying Qu,Daniel Primetzhofer,Miguel A Arvizu,Zhen Qiu,Umut Cindemir,Claes-Göran Granqvist,Gunnar A. Niklasson +7 more
TL;DR: Time-of-flight elastic recoil detection analysis provided unambiguous evidence that both Li+ ions and chlorine-based ions participate in the rejuvenation process, providing new perspectives for developing ion-exchange-based devices embodying nickel oxide.
Journal ArticleDOI
Electrochromic WO3 thin films attain unprecedented durability by potentiostatic pretreatment
Miguel A Arvizu,Huiying Qu,Huiying Qu,Umut Cindemir,Zhen Qiu,Edgar A. Rojas-González,Daniel Primetzhofer,Claes-Göran Granqvist,Lars Österlund,Gunnar A. Niklasson +9 more
TL;DR: Potentiostatically pretreated electrochromic WO3 films show much better durability under very harsh cycling conditions than untreated films, and are shown to be compatible with high-performance liquid chromatography standards.
Journal ArticleDOI
Exhaled breath analysis for gastric cancer diagnosis in Colombian patients.
Cristhian Manuel Durán-Acevedo,Aylen Lisset Jaimes-Mogollón,Oscar Eduardo Gualdrón-Guerrero,Tesfalem Geremariam Welearegay,Julián David Martínez-Marín,Juan Martín Cáceres-Tarazona,Zayda Constanza Sánchez-Acevedo,Kelvin de Jesús Beleño-Sáenz,Umut Cindemir,Lars Österlund,Radu Ionescu +10 more
TL;DR: A new and non-intrusive methodology for early diagnosis of gastric cancer that may be deployed in regions lacking well-developed health care systems as a prediagnosis test for selecting the patients that should undergo deeper investigations (e.g., endoscopy and biopsy).
Journal ArticleDOI
Optoelectronic CMOS Power Supply Unit for Electrically Isolated Microscale Applications
O. Aktan,Baykal Sarioglu,Umut Cindemir,Saruhan Onur Unlu,Gunhan Dundar,Senol Mutlu,Arda D. Yalcinkaya +6 more
TL;DR: In this paper, the authors presented a CMOS power supply unit for electrically isolated microscale applications, where the provision of electrical power is not appropriate through wiring, where a miniature fiberoptic platform consisting of an inclined silicon mirror fabricated using bulk micromachining is coupled to the monolithic integrated photodiode/dc-dc converter system, to yield a stand-alone optical power supply.
Journal ArticleDOI
Fabrication of ultra-pure gold nanoparticles capped with dodecanethiol for Schottky-diode chemical gas sensing devices
Radu Ionescu,Radu Ionescu,Umut Cindemir,Tesfalem Geremariam Welearegay,Raul Calavia,Z. Haddi,Zareh Topalian,Claes-Göran Granqvist,Eduard Llobet +8 more
TL;DR: In this article, the first observation of Schottky-diodes fabricated from nanomaterials based on metallic nanoparticles was made using X-ray photoelectron spectroscopy.
