“…With such advantages, current state-of-the-art technologies used for concrete production should also be used to produce hemp concretes to study their influence on the properties of hemp concrete. These technologies have been employed to study the mechanical performance of cement concrete, such as 3D printing [33][34][35][36]. These works highlight the potential of the 3D printing of concrete.…”

The search for environmentally friendly and low-carbon-footprint construction materials continues progressively. Researchers are now interested in innovative materials that connect with the principles of sustainable construction, and materials such as hemp concrete prove to be promising. This article presents the results of a study that aimed to evaluate the hygrothermal performance of hemp concrete integrated into the building envelope using the hygrothermal tool WUFI Pro 6.2. The simulation model was compared and verified with existing models before its utilization for this study. The results of this verification were in good agreement, which gave us more confidence in its application for further parametric studies of building envelopes in hot climate zones. Three wall systems were simulated: (i) a wall system with hemp concrete, (ii) a compressed earth block wall, and (iii) a cement block wall. The most important variables used in the simulations were the hygrothermal properties of the materials or wall components and the incident solar radiation. The simulation results showed that hemp concrete has good thermal performance and temperature and humidity regulation capabilities of the building envelope. The interior surface temperatures of the hemp concrete walls were between 22.1 °C and 24.6 °C compared to the compressed earth block and cement block walls, where the surface temperatures were between 22.0 °C and 27 °C and between 21.2 °C and 28.7 °C, respectively, and between 23 °C and 45 °C for the exterior temperatures. These values remain the same with the increase in exterior temperatures for hemp concrete walls. In conclusion, hemp concrete could be a great alternative material for use in construction for hot climate zones.

“…It is important that the substrates for printing are varied in a wide range including polymers, paper, textiles, biomaterials, concretes, etc. [ 7 , 8 , 9 ]. Flexible printed electronics are suitable for designing electrodes, displays and antenna arrays, sensors, batteries, photovoltaic cells, radio frequency identification (RFID) tags, light-emitting diodes (LEDs) [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ], biomedical devices for deep-tissue sensors [ 20 ] and in electronic skins [ 21 ], and could be used in the future for biomedical devices.…”

Silver-based metal–organic decomposition inks composed of silver salts, complexing agents and volatile solvents are now the subject of much research due to the simplicity and variability of their preparation, their high stability and their relatively low sintering temperature. The use of this type of ink in inkjet printing allows for improved cost-effective and environmentally friendly technology for the production of electrical devices, including flexible electronics. An approach to producing a silver salt-based reactive ink for jet printing has been developed. The test images were printed with an inkjet printer onto polyimide substrates, and two-stage thermal sintering was carried out at temperatures of 60 °C and 100–180 °C. The structure and electrical properties of the obtained conductive lines were investigated. As a result, under optimal conditions an electrically conductive film with low surface resistance of approximately 3 Ω/square can be formed.
