The construction industry is experiencing changes in its processes and work methods, and the advancement of new technologies in recent decades has led to a new concept known as Construction 4.0, coined in 2016 in Germany. Since its definition is still diffuse, it was deemed necessary to conduct a review on the publications in this field to grasp how this concept is being understood. For that purpose, a bibliometric analysis was conducted among 260 research articles using seven keywords. The results reveal that the number of publications is growing exponentially, with the USA, the UK, and China being leaders in this field; besides, four technologies are essential to understand Construction 4.0 at present time: 3D printing, big data, virtual reality, and Internet of Things. The results of this review suggest that further reviews should be conducted every 3 years to grasp the rapid evolution of Construction 4.0.

“…In addition, these fossil fuels produce environmental pollution of gases, such as nitrogen oxides, sulfur dioxide, and CO 2 , which may cause the greenhouse effect. , Therefore, hydrogen energy has been attracting considerable attention because it is green, pollution-free, low in carbon, renewable, − and other advantages. However, hydrogen is inflammable, explosive, and diffusive under normal conditions, and therefore, lots of studies have been devoted to study the safe storage and use of hydrogen energy constantly. − Generally speaking, there are three ways to store hydrogen: solid hydrogen storage, , gaseous hydrogen storage, and liquid organic hydrogen storage. − Among them, solid hydrogen storage, which has the advantages of good convenience, high-density hydrogen storage, low cost, and a relatively high safety factor, is considered to be a potential storage method and has application prospects in the future. The existing solid hydrogen storage includes carbon adsorption storage ( e.g.…”

MgH 2 is well known as a potential hydrogen storage material. However, its high thermodynamic stability, high dissociation temperature, slow absorption, and desorption kinetics severely limit its application. Aiming at these shortcomings, we try to improve the hydrogen storage property of MgH 2 by doping with transition metal Sc atoms. The structures and electronic and hydrogen storage properties of Mg−Sc−H systems have been systematically studied by combining the crystal structure analysis by particle swarm optimization and density functional theory method. The results show that the structure of MgScH 8 with the R3 space group is the most stable one, which is proved to be a wide-band gap (2.96 eV) semiconductor. The possible decomposition pathways, which are crucial for the applicability of R3-MgScH 8 as a hydrogen storage material, are studied, and the pathway of MgScH 8 → ScH 6 + Mg + H 2 is found to be the most favorable one under 107.8 GPa pressure, while above 107.8 GPa, MgScH 8 → Mg + Sc + 4H 2 becomes the most thermodynamically stable pathway and releases the maximum amount of hydrogen. Based on the root mean square deviation calculation, it is found that R3-MgScH 8 begins to melt at 400 K. The result of ab initio molecular dynamics simulations shows that the hydrogen release capacity (4.04 wt %) can be easily achieved at 500 K, thus making MgScH 8 a potential hydrogen storage material.

“…However, the main problem in using hydrogen as fuel in the future is finding the right way to store it. Hydrogen storage in the solid phase is one of the most promising solutions because of safety reasons, the reversibility of the process and, above all, its high capacity [1][2][3][4][5][6][7][8].…”

The Mg-Li binary system is characterized by the presence of α-Mg(Li) and β-Li(Mg) phases, where magnesium exists in ordered and disordered forms that may affect the hydrogenation properties of magnesium. Therefore, the hydrogenation properties of an AZ31 alloy modified by the addition of 4.0 wt.%, 7.5 wt.% and 15.0 wt.% lithium were studied. The morphology (scanning electron microscopy (SEM)), structure, phase composition (X-ray diffraction (XRD)) and hydrogenation properties (differential scanning calorimetry (DSC)) of AZ31 with various lithium contents were investigated. It was found that the susceptibility of magnesium in the form of α-Mg(Li) to hydrogenation was higher than that for the magnesium occupying a disordered position in β-Li(Mg) solid solutions. Magnesium hydride was obtained as a result of hydrogenation of the AZ31 alloy that was modified with 4.0 wt.%, 7.5 wt.% and 15.0 wt.% additions of lithium, and was characterized by high hydrogen desorption activation energies of 250, 187 and 224 kJ/mol, respectively.
