Collective effects are a typical nuclear feature that refers to the behavior of a group of N fermions (protons and neutrons) within the atomic nucleus. Our interest lies in light nuclei only. Thus, we consider here, using the Lipkin model, a small-N fermion system at low-temperature T and discover -collective phenomena. Our fermion-model simplicity allows one to gain insight into collective fermion behavior. We focus attention, for N<20, on several quantifiers. These include standard ones related to thermal [...]

This communication was brief to show how high conjugated carbon-based structures and carbon allotropes could participate as electron shuttles, semiconductors, quantum emitters, and Optoelectronic processors within confined nanostructured organized systems. In particular, it was focused on nanoassemblies such as vesicles, micelles, and lipidic nanoparticles and incorporated insights from other types of nanomaterials that could afford to develop new organized systems. In these cases, the term organized system was use [...]

Organics found in landfill leachate (humic acids, fulvic acids, and hydrophilic fraction) have a solid ability to absorb ultraviolet (UV) radiation, which negatively affects UV disinfection; leachate ultraviolet quenching substances (UVQS) can, therefore, have a significant impact on the cotreatment of landfill leachate and sewage in wastewater treatment plants. On the other hand, per- and polyfluoroalkyl substances (PFAS), which pose potential risks to the environment and human health, commonly exist in landfill l [...]

This review intended to resume key Research reports and publications that open many themes and topics related to Carbon-based semiconductors and Quantum emitters. The Design and synthesis of highly pure materials such as Graphene, Carbon Nanotubes, fullerenes, and other Carbon-based allotropes were shown. They presented their most important and promising properties concerning new studies and developments in photonics. Carbon-based Quantum dots, semiconductors, and higher sized Nanoplatforms allowed us to discuss fu [...]

The results of stress analysis of a ceramic matrix composite (CMC) vane using a physics-based model developed for two-dimensional woven CMCs are presented. The model considers the inherent defects and micromechanical damage in woven CMCs along with time-dependent deformation of the constituents. Predictions include damage state under general load conditions and the global deformation response of the vane. Strain-gage data from burst tests are compared to strain predictions obtained using the model. Results from tim [...]

This mini-review discussed the best-known chemical and synthetic methodologies used in the last years to modify carbon allotropes, with an interest in nanotechnology. In this perspective, chemistry with optoelectronics applications and recent trends within bio-applications focusing mainly on graphene and its derivatives were considered. So, the mini-review intended to focus on methodologies to add functional groups with varied reactivities, polymer chemistry, and nanoscale control. These methodologies provide insig [...]

In this work, we apply a multiphysics approach to fused deposition modeling to simulate extrusion and solidification. Restricting the work to a single line scan, we focus on the application of polylactic acid. In addition to heat, momentum and mass transfer, the solid/liquid/vapor interface is simulated using a front-tracking, level-set method. The results focus on the evolving temperature, viscosity, and volume fraction and are cast within a set of parametric studies, to include the printing and extrusion speed, a [...]

The Inert soil obtained from the Ghazipur Municipal Solid Waste landfill located in East Delhi, India has been used as the starting material for the work described in this paper. This mountain-like monster is often in the news for its bad smell, pollution of the groundwater in the area from its leachates, and the occasional fires in it endangering the lives of the people living nearby. Landfills produce many greenhouse gases (CO2, CH4, CO, HCHO, H2S, and NH3) which are poisonous and cause environmental pollution in [...]
