The tribological behavior of moving components and tooling in the automotive industry is a critical issue for improving tool life and increasing efficiency. This work discusses the effects of Zn and ZnO nanoparticle additives homogeneously dispersed within a metal-forming synthetic fluid at various filler fractions: 0.01, 0.05 and 0.10wt.%. Nanolubricants were evaluated under scuffing conditions at extreme pressures (EP) conditions using a four-ball tribotester in order to obtain the load-carrying capacity (poz) behavior, and overall tribological characteristics. This method has shown, with great precision, the influence of the nanofillers on the EP behavior of conventional lubricants. Worn surfaces were characterized through Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) to determine the tribological mechanisms of nanoparticles. An Alicona 3D surface measuring system was used for measuring the surface roughness of the wear scars. Both nanoparticles exhibited better friction-reducing and anti-wear properties compared to the base synthetic fluid. For Zn-based nanolubricants, an enhancement of ~180% in poz was obtained with 0.10wt.%, showing the effect of the spherical nanostructures that were tribosintered onto the surface due to the EPs of the test. Furthermore, the highest enhancement in poz (up to 250%) was achieved with incorporation of 0.10wt.% of ZnO demonstrating the potential of nanolubricants for improving the efficiency of mechanical components.

The relationship between architecture and technology throughout history has continually meant the discipline's adaptation to new technological advances. Simultaneously, the contemporary city allows us to see the processes of evolution or involution in those who think about it, design it, build it and live it. In recent years, new technologies have been introduced that allow the morphological flexibility of buildings, such as responsive architecture, where the shape of the building can be reprogrammed and adapted to its spatial environment. These technologies function as a programmed response mechanism from catalytic elements thrown by the environment, these catalysts can vary from sensory elements to bio-climatic elements. This paper seeks to reflect on a new turn of these new adaptable technologies, where the human being himself is the key catalyst in the responsive process of these new buildings. This strives to promote a methodology where, through the union of the user participation and responsive environments, it is possible to introduce a new concept of Participatory Design. In this way, a new possibility can be introduced to create buildings that are constantly at the forefront of the social needs of the communities, where users not only manage to be part of the construction and design of the building but are also part of its constant evolutionary process.
