Recuperação dos tubos de ensaio quebrados e trincados dos laboratórios de Química da Universidade Tecnológica Federal do Paraná - Campus Bato Branco
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de QuímicaQuímicaUTFPR, 2016-06-06)
The borosilicate glasses are widely used in chemical laboratories, as they have Higher thermal and mechanical resistance. There is an excessive discard of broken or cracked glass laboratory because no recovery programs of ...
Defect-induced photoluminescence of powdered silica glass
(2008-03-27)
Visible photoluminescence was generated in standard soda-lime-silica glass powder, mechanically milled in a high-energy attrition mill. The broad emission band maximum shows a linear dependence on the exciting wavelength, ...
