    Innovative Safety Systems in Building Sites

    The construction industry is one of the industry sectors where the greatest number of accidents occur. The percent-age of accident risk is closely linked to the organization's organizational choices. Wrong choices and behaviors de-termine a consistent increase. The goal is to identify a pre-vention strategy that is not perceived as a major financial burden on the part of the enterprise, but as an investment opportunity. The continuous increase in accidents in construction sites is driving intensification of efforts and investments in techno-logical research to identify effective solutions for accident prevention. An innovative solution consists of the latest generation RFId (Radio-Frequency Identification) systems, which, if applied to medium and large building sites, will reduce the number of injuries while at the same time increasing em-ployee accountability in the use of Individual protection devices. RFId sensors, installed on both worker and on-site equip-ment and machinery, access control, etc., allow you to define an "intelligent" building site through constant moni-toring and management of all stages and work processes. New systems enable "real-time" intervention and are an important support for identifying risk situations and organ-izing remedial measures

    The increasing demand of portable energy in terms of cycle life for electronic devices such as smartphones, tablets and computer or the high stability required for medical application and the high energy density for smart energy grids and electrified transport require a breakthrough in performance lower cost, safety and environmental compatibility. indeed, the conventional energy storage devices are characterized by limited specific capacity and energy density due to the intrinsically properties of the cathodic active materials i.e. LiCoO2 with specific capacity if 150 mAhg-1 and a theoretical energy density of 550 WhKg-1. therefore, the deep investigation and optimization of new classes of electrodes proposed in this work of thesis, may shed light on the possible candidates for a new generation of energy storage devices characterized by high energy density and environmental compatibility. Furthermore, one of the main topic of this work is the study of new classes of electrolytes characterized by low flammability and high ion mobility properties in order to ensure high performances and safety leve
