Although CMF and CNF have been successfully obtained from the mentioned technologies, several drawbacks still exist such as high energy consumption and chemical agents required. Refining has been widely used as pretreatment combined with other defibrillation treatments such as homogenization to obtain CMF/...
The authors propose a scalable solid phase process to upcycle aluminum scrap into a high-strength alloy with 200% strength improvement. The process reduces energy consumption and carbon emissions while making customizable materials from waste by tailoring the chemical composition. ...
Along with chemical free energy and electrical free energy, mechanical force completes the sources of free energy available to cells, and all the free energy sources are coupled to downstream pathways that regulate physiological activity. For instance, stem cell phenotypy is affected by mechanical ...

which modifies the oxide. This coating is a chemical conversion of the substrate to its oxide and causes its porous growth in all directions of the metal surface, which produces excellent adhesion to the material, provides protection against wear, abrasion and corrosion. In magnesium alloys, the ...
Metamaterials are engineered materials that have properties not usually found in nature, primarily due to their structure, rather than chemical composition. Early metamaterial research focused on electromagnetic properties, such as materials with negative permittivity and permeability [1]. More recently, int...
In this situation, the ring settles into a steady state in which energy is systematically withdrawn from the heat bath (gas) and delivered to perform mechanical work. 3. Operational Modes of the Programmable Demon More generally, the behavior of our ring depends on four parameters that we ...
(Bukowno, Po-land). The MnO filler consisted of 92.5% grains with a diameter below 0.1 mm and 7.5% grains with a diameter in the range of 0.1–0.315 mm. The MR filler consisted of grains with a diameter below 0.1 mm (100%). The chemical composition of the MR and MnO fillers are ...
