Along the lines of green actions, many capitals have declared ambitious climate neutrality goals to establish their infrastructure and citizens with net zero. The increasing emissions of greenhouse gases pave the way for increasing the earth’s temperature, which leads to danger to life, mainly due to the drying up of water reserves. Thus, abrupt climate change negatively affects the worldwide ecosystems and biological diversity. The common effects of climate change are caused by droughts, forest fires, cloudbursts, cyclones, earthquakes, heavy rains, snow, cold and heat waves, etc. From North to South America and from East to West Asia, extreme weather events are often experienced. This interns to the rapid movement of global warming. The impact of extreme weather conditions must be urgently normalized by adopting ecological practices, green scientific protocols, time-bound government strategies and comprehensive climate action.

Based on this knowledge, a set of polymer beams that act compositely with a concrete slab was designed and produced. The aim of the research was to exploit the low weight and high strength of the polymer I sections and combine them with the high stiffness of the concrete slab, which forms the upper part of the cross-section. The advantage of fibre-reinforced polymer (FRP) beams is their anisotropy, where the strength of the material is increased by placing the fibers uniformly in one direction, and the composite members are then loaded in the most reinforced direction. To ensure the interaction between the polymer element and the concrete slab, strip shear connections with a precisely defined shape were developed and used. The designed composite beam simulates a precast component that can be used in bridge structures for short and medium spans. The pre-cast beams were subjected to four-point bending. Apart from the total deflections of the structure, the stresses in the cross-section of the composite material and the relative deformations/strains on the surface of the concrete part of the cross-section were monitored during the test. The entire experiment yielded new results both in laboratory and theoretical terms, not only regarding the interaction between materials with distinct properties, but also the properties of composites themselves.

The results presented here provide a prediction of the mechanisms involved in the aging of GFRP pultruded bridge profiles and predict the properties microscale changes with time and remaining life of GFRP under real environmental degradation impacts and under simulated laboratory conditions. The outermost layers of FRP (fiber reinforced polymer) composites are damaged mainly due to UV radiation. Radiation also induces remarkable microstructural changes depending on wavelength and intensity, and oxygen availability, ultimately leading to polymer chain scission. A scanning electron microscope (SEM) was used to investigate the degradation mechanism of the GFRP samples exposed to, among other things, UV radiation and water vapor condensation. Glass fiber reinforced polymer GFRP pultruded profiles have great potential in the construction industry, presenting several advantages compared to traditional materials, including the potentially improved durability under environmental influences.

Summary This work is part of a systematic study of the energy barriers for the penetration of several molecules, such as He, H2, CO, CO2, H2O, NH3, CH4 etc, through nanoporous single-layer graphene, with pores of different shape, size and type.

In this work, we focus on the permeation of CO2 through graphene pores that are constructed when neighboring carbon atoms of the graphene layer are removed from the structure, and nitrogen atoms have replaced the carbon atoms in the boundary of the pore. The energy barriers for each different pore are calculated using 2 different ReaxFF potentials along a path that the molecule would ideally follow to pass from one side of the membrane to the other through the pore. Using the calculated values ​​of the energy barriers, we estimate permeances using the kinetic theory of gases. We provide estimates of the preferred sizes and structures of the pores for permeability and demonstrate the capability of nanoporous graphene for CO2 separation.

In addition, the chemical reaction that gives rise to the formation of SiC has CO and CO2 as by-products. Therefore, in this work, an alternative method was developed to produce SiC/Si composites with waste from the wood industry as the main raw material. SiC/Si composites were prepared by infiltrating molten silicon into carbon preforms at 1500 °C. The carbon preforms were obtained by pyrolysis (in an inert Ar atmosphere) of four types of resin-carbon mixtures. The carbon used in the mixtures was obtained by pyrolysis of sawdust powder. The mechanical and thermomechanical behavior in uniaxial compression was studied at a constant compression rate of 0.05 mm/min at different temperatures (ambient temperature, 1100 °C and 1400 °C). The maximum strength values ​​found were in the range of 58 and 384 MPa, while the Young’s modulus values ​​were between 40 and 120 GPa. The porosity found in the materials was between 1 and 4%. Finally, the prepared compounds presented a homogeneous microstructure of interconnected silicon carbide in gray contrast and dispersed and uninterconnected whitish phases of uniformly distributed silicon.

The model considers the effects of the position of the nodes along the longitudinal and vertical axis of the beam. The numerical models were validated by bending tests carried out on six beams. The actual three-dimensional geometry of knots and related fiber anomalies were determined accurately based on an algorithm proposed previously by the authors. The elastic-plastic constitutive law
