Additive manufacturing is transforming modern industries by enabling the production of lightweight, complex structures while minimizing material waste and energy consumption. This review explores its evolution, covering historical developments, key technologies, and emerging trends. It highlights advancements in material innovations, including meta...

Choosing a suitable prosthesis to restore the functionality of the hip joint is a complex problem. The stem geometries, materials, and type of hip damage are critical factors for avoiding potential issues (aseptic loosening, fracture, and natural wear and tear). Comparing the available stems to select the best option is not straightforward because...

In this work, we present the simulation study of a LiBr-H2O solar thermal absorption air conditioning system, installed in an isolated primary school in the community of Puertecitos, Mexico. The collection system consists of 110 m2 of evacuated tube solar collectors that produce the thermal energy needed to activate the chiller, while four cooling...

In this work, we present an absorption cooling system with 35 kW capacity driven by solar thermal energy, installed in the school of Puertecitos, Mexico, an off-grid community with a high level of social marginalization. The cooling system provides thermal comfort to the school’s classrooms through four 8.75-kW cooling coils, while a 110-m² field o...

This paper presents a novel LiBr/H 2 O absorption cooling and desalination system with three pressure levels which uses seawater as a cooling medium and is activated by solar thermal energy. This systemhelps counteract coastal populations’ thermal conditioning and water supply problems. In order to showtechnical feasibility, Aspen Plus was used to...

In this work an economic and technical analysis on a hybrid Photovoltaic (PV)-Concentrated solar power (CSP) system, to be used as an energy source in isolated microgrids, is conducted using the microgrid in Puertecitos, Baja California, Mexico as a case study. The PV-CSP system uses a field of solar concentrators with thermal storage to activate a...

In this paper, we present a comparative study of two compound parabolic concentrators with a concentric tube as absorber positioned longitudinally in the North-South and East-West directions. The analysis includes the design, modeling, construction, experimentation and validation of the concentrators. It was defined as an object of study a CPC with...
