No. of bitstreams: 0 Previous issue date: 2020-06-30; The modification of CeO2 with rare-earth elements opens up a wide range of applications as biomedical devices using infrared emission as well as magnetic and gas-sensing devices, once the structural, morphological, photoluminescent, magnetic, electric, and gas-sensing properties of these systems are str...
Piezoelectric energy harvesting device based on quartz as a power generator
Araujo, Luis A.O.; Foschini, Cesar R. [UNESP]; Fortulan, Carlos A.Made available in DSpace on 2020-12-12T01:20:29Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-01-01; The idea of harvesting ambient vibration energy to generate electricity has become a promising research field over the past decade due to the reduced power requirements of small electronic components. The motivation of vibration-based energy harvesting (EH) is to power such devices (e.g., sensor network...
Evidence of ferroelectric behaviour in CaCu3Ti4O12 thin films deposited by RF-s...
Foschini, Cesar R. [UNESP]; Hangai, Bruno [UNESP]; Ortega, Pedro Paulo [UNESP]; Longo, Elson [UNESP]; Cilense, Mário [UNESP]Made available in DSpace on 2020-12-12T02:27:40Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); The origin of abnormal ferroelectric and unusual piezoelectricity in the polycrystalline CaCu3Ti4O12 (CCTO) thin films deposited by RF-sputtering on Pt/Ti/SiO2/Si (100) substrates was explored. The CCTO thin films, deposited at room temperat...
Nonvolatile memories
Rocha, Leandro S.R. [UNESP]; Simões, Alexandre Z. [UNESP]; Cortés, Johan A. [UNESP]; Ramirez, Miguel A. [UNESP]; Moura, FranciscoMade available in DSpace on 2020-12-12T02:39:06Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-01-01; The need for faster, smaller, cheaper and energy-efficient electronic devices has been growing continuously in the last decade, with the conventional data storage technologies (i.e., static random access memory and dynamic random access memory), which have been so far fulfilled by CMOS-charge storage-ba...

A new approach to measure the elasticity modulus for ceramics using the deforma...
Foschini, Cesar R. [UNESP]; Souza, Edson A. C. [UNESP]; Borges, Ana F. S.; Pintão, Carlos A. F. [UNESP]Made available in DSpace on 2018-12-11T16:43:38Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-08-01; This paper presents an alternative method to measure the modulus of elasticity to traction, E, for relatively limited sample sizes. We constructed a measurement system with a Force sensor (FS) and a Rotation movement sensor (RMS) to obtain a relationship between force (F) and bending (ΔL). It was possib...
