Metal-ion effects on the polarization of metal-bound water and infrared vibrational modes of the coordinated metal center of Mycobacterium tuberculosis pyrazinamidase via quantum mechanical calculations
(American Chemical Society, 2014)
Mycobacterium tuberculosis pyrazinamidase (PZAse) is a key enzyme to activate the pro-drug pyrazinamide (PZA). PZAse is a metalloenzyme that coordinates in vitro different divalent metal cofactors in the metal coordination ...

Heavy metal resistance strategies of acidophilic bacteria and their acquisition: Importance for biomining and bioremediation
(2013)
Microbial solubilizing of metals in acid environments is successfully used in industrial bioleaching of ores or biomining to extract metals such as copper, gold, uranium and others. This is done mainly by acidophilic and ...
Environmental conditioning effects on the mechanical properties of titanium fiber-metal laminates
(2013-01-01)
Fiber metal laminates (FML) have been particularly attractive for aircraft structures. While weight reduction and improved damage tolerance characteristics were the prime drivers to develop this new family of materials, ...
Barreiras na qualificação da manutenção em empresas de pequeno e médio porte do setor metal mecânico
(Universidade Federal de Santa MariaCentro de Tecnologia, 2015-12-04)
Equipment failure is one of the various reasons for not meeting customer expectations. In some instances, this stems from the wrong procedures being performed whilst undertaking their maintenance management. This study ...

Enhancement of mechanical properties of metallic glass nanolaminates via martensitic transformation: atomistic deformation mechanism
(Elsevier, 2019)
Metallic glasses with embedded crystalline phases have been experimentally reported to exhibit enhanced
mechanical properties. To further explore this observation, we employed molecular dynamics simulations to
study ...
