Caracterização e avaliação de filmes metálicos para uso em ultra-alto vácuo
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, 2007-11-27)
The construction of ultra-high vacuum chambers (UHV) for particle accelerators demands pressure in the range of 10-8 Pa, and this is particularly difficult to achieve in chambers with the length to traverse section rate ...
Technical requirements for substation equipment
(CIGRE, 2008-12)
In recognition of a renewed interest in transmission voltages exceeding those in common usage today, SC A3 established WG A3.22 Technical Requirements for Substation Equipment exceeding 800 kV. The WG was tasked with ...
Molecular Anchoring to Oxide Surfaces in Ultrahigh Vacuum and in Aqueous Electrolytes: Phosphonic Acids on Atomically-Defined Cobalt Oxide
(Royal Society of Chemistry, 2019-10)
In this work, we investigated the interaction of phenylphosphonic acid (PPA, C6H5PO3H2) with atomically-defined Co3O4(111) thin films, grown on Ir(100), under ultrahigh vacuum (UHV) conditions and in the electrochemical ...
Effect of soil type on wood chemical constituents and calorific values of 33-year-old Corymbia citriodora
(2021-01-01)
Red Latosol (LV), Red Nitosol (NV) and Quartzarenic Neosol (RQ) have different physical and chemical characteristics, as well as water holding capacity. This study aimed to determine how such differences cause changes in ...
Direct recoil spectroscopy of adsorbed atoms and self-assembled monolayers on Cu(001)
(Elsevier, 2014-01)
We present results of adsorption experiments of Sn and 1,4-benzenedimethanethiol (BDMT) on Cu(001), which illustrate the capabilities of a new setup specifically designed to perform surface studies by Direct Recoil ...

Webinar 'Uso seguro de equipamentos médico-assistenciais', realizado pelo Proqualis em junho de 2018 com o engenheiro clínico certificado Lúcio Flávio de Magalhães Brito, diretor da Engenharia Clínica Ltda.
An Integrated 350V Dimmer
(IEEE, 2020)
The design of an almost fully integrated phase-cut dimmer is presented. The circuit was designed on a 1um ultra high voltage (UHV) MOS technology in a silicon-on-insulator (SOI) wafer. The dimmer can operate with a duty ...
