The pandemic triggered by the SARS-CoV-2 virus has produced worldwide interruptions of face-to-face teaching activity in both schools and universities. In Italy, quarantine began second half February 2020 lasted for all semester lectures. University Bologna, where authors present article are based, developed activated several interfaces necessary to efficiently deliver online courses with utmost speed. framework used is based on a common platform, Microsoft TEAMS, available teachers at...
In recent years, wearable technologies have attracted great attention in physical and chemical sensing applications. Wearable pressure sensors with high sensitivity low range (<10 kPa) allow touch detection for human-computer interaction the development of artificial hands handling objects. Conversely, that perform a (up to 100 kPa), can be used monitor foot distribution, hand stress during movements heavy weights or evaluate cyclist’s pattern on bicycle saddle. Recently, we developed...
The use of wheat middlings (WM) and rice husks (RH) as biofillers for mixing with poly(lactic acid) (PLA) matrix to produce new 3D-printable biocomposites was assessed. Filaments containing 10 20 wt.% agro-waste-derived were manufactured and, the sake comparison, filaments neat PLA also produced. obtained characterized via thermogravimetric analysis (TGA) differential scanning calorimetry (DSC), showing potential further application in additive manufacturing processing. Three-dimensionally...
Abstract Blends of small‐molecule organic semiconductors (OSCs) and insulating polymers in Organic Field‐Effect Transistors (OFETs) are mainly used to assist the solution‐processing OSCs, but they can also reduce interfacial charge traps due vertical phase separation. Such known affect both electrical response radiation‐induced collection capability these devices. This study aims optimize separation blend films 1,4,8,11‐tetramethyl‐6,13‐triethylsilylethynyl pentacene (TMTES) polystyrene (PS)...
The effect of Zr addition on the melting temperature CoCrFeMnNi High Entropy Alloy (HEA), known as “Cantor’s Alloy”, is investigated, together with its micro-structure, mechanical properties and thermomechanical recrystallization process. base Zr-modified alloys are obtained by vacuum induction mechanically pre-alloyed powders. Raw materials then cold rolled annealed. occurred during heat treatment cold-rolled HEA. characterized X-ray diffraction, electron microscopy, thermal analyses,...
Recent studies in the field of safety workplace have focused on developing new sensors and procedures to detect monitor body stress due repeated or highly stressful movements that, long term, could lead painful traumas accidents. Today, common method used evaluate risk activities is based evaluations that are subjective supported by difficult time-consuming video analysis. However, recent developments wearable sensors, particular pressure allow for innovative alternatives. The main...
Nanocrystalline nickel was prepared by a planetary ball milling apparatus working in vacuum of 10−4 Pa the 150–300 K temperature range. The kinetic process and microstructure evolution upon annealing were followed x-ray diffraction mechanical spectroscopy measurements. It observed that thermal up to 600 induces strong reduction internal strains without significant grain growth. Measurements elastic energy dissipation dynamic modulus as function showed nanocrystalline samples, anelastic...
The high entropy alloy (HEA) of equiatomic composition CrNiFeCoMn and with FCC crystal structure was additively manufactured in a selective laser melting (SLM) process starting from mechanically alloyed powders. as-produced shows fine nitride σ phase precipitates, which are Cr-rich stable up to about 900 K. precipitates increase number dimensions after long-period annealing at 900-1300 K, change the HEA mechanical properties. Higher aging temperatures furnace, above 1300 turn into single...
The use of Boron as an energy storage medium in the framework solar systems development is suggested, highlighting its potential advantages. issue which considered here mainly that reducing waste connected with power transfer from areas high productivity to highly industrialized areas, such those Europe, where needed. Both production and Hydrogen or build up lines give rise loss can be 50% produced energy. A cycle described used a means store transport site location stored will used. This...
An automatic vibrating reed apparatus for internal friction and elastic modulus measurements in solids is described. The equipped with a resistive heater up to 1400 K. A magnetic field (up 250 kAt/m) also available the 300–1000 K range. Measurements as function of temperature and/or can be easily carried out.

In the present research, results are presented regarding anelasticity of 99.999% pure aluminum thin films, either deposited on silica substrates or as free-standing sheets obtained by cold rolling. Mechanical Spectroscopy (MS) tests, namely measurements dynamic modulus and damping vs. temperature, were performed using a vibrating reed analyzer under vacuum. The temperature curves films exhibit two peaks which tend to merge into single peak specimen thickness increases above 0.2 µm. thermally...
