The modification of our energetic mix is one of the important challenges to mitigate climate change. Various solutions are studied, and we will probably use most of them in the future. One of these solutions is metal combustion. Indeed, metals have important energy properties, and the combustion of metal powder does not produce greenhouse gases exc...

Local tissue and serum metal ions have been shown to be elevated in some metal-on-metal and metal-on-polyethylene joint replacements. Local elevations have been linked to adverse local tissue reactions in some patients, and systemic elevation has been less commonly implicated cardiac and neurologic issues. Using a prospective study design, we aimed...

The most prevalent type of dementia is Alzheimer's disease (AD), which is currently incurable. Existing treatments for Alzheimer's disease, such as acetylcholinesterase inhibitors, are only effective for symptom relief. Disease-modifying medications for Alzheimer's disease are desperately required, given the enormous burdens that the disease places...
What if small metal particles were the future of energy? Combustion of these metal particles releases a large amount of energy and has the advantage of not emitting carbon dioxide. These particles, burning in air, produce metal oxides which can then be regenerated using solar energy. This cycle energy production / recycling can make it possible to ...

To explore the correlation of AL-based food consumption, known to have negative impact on health, and Al plasma levels with pregnancy status. A cross-sectional study was conducted on 75 participants, including 50 pregnant women. Al plasma levels were analyzed by ET-AAS. Exposure to food was positively correlated to Al mean plasma levels (reaching 2...

Aluminum (Al) is a ubiquitous environmental pollutant representing a significant global health hazard to human and animal health, including chicks. Al toxicity causes oxidative stress, leading to tissue injury, and consequently causes various diseases. NRF2 signaling is vital for protecting cells against oxidative stress. Nuclear xenobiotic recepto...
The high thermal and low electrical conductivities of ZnO ceramics have hindered their thermoelectric applications. The doping of ZnO with group 3 elements can enhance the thermoelectric properties. In this work, Al (2 at%) doped ZnO powder was sintered using spark plasma sintering at varying parameters (such as temperature (550-700 ℃), pressure (2...
The 6061-T6 aluminum alloy is used for the fabrication of pressure vessels in nuclear research reactor. Neutron radiation causes microstructural changes that harden the material (45 and 60% increase in the yield and mechanical strengths respectively) and deteriorate its ductility (drop from 9 to 15% in the total elongation). Despite these changes i...

Al(OC(CF3 )3 )(PhF) reacts with silanols present on partially dehydroxylated silica to form well-defined ≡SiOAl(OC(CF3 )3 )2 (O(Si≡)2 ) (1). 27 Al NMR and DFT calculations with a small cluster model to approximate the silica surface show that the aluminum in 1 adopts a distorted trigonal bipyramidal coordination geometry by coordinating to a nearby...
In order to produce functional parts in Wire Arc Additive Manufacturing (WAAM), mastering parts quality is a key challenge. The literature highlights the connection between thermal conditions and part defects. Thus, monitoring a thermal parameter, for instance the melt pool in this study, is a crucial indicator to describe parts quality. The paper ...
