Energy used for specific jobs

    One thing that is not discussed here is the energy used for specific jobs only power.  For example, refrigerators turn on and off. Therefore, a refrigerator that runs almost full time can be cooled with the same energy but at lower power than a cycle in which each cycle consumes more energy. Energy = Power for time. Secondly, all kinds of devices now use motors in inverters or other electronic devices that control the frequency or voltage, giving the motors only the speed and, therefore, the power needed to perform a specific job. On-demand water pumps come to mind and offer only the pressure and flow rate required and nothing more. Needless to say, the power required is only what is needed for that pressure and volume. So far, less energy is wasted. Apparently, the team that is discussing works according to this principle. But, whether DC is operated from rectified AC or inverted DC to Poly Phase AC, the specific design used is unknown.

Transfer technique produces wearable gallium nitride gas sensors

------------------------------------------------ Transfer technique produces wearable gallium nitride gas sensors A transfer technique based on thin sacrificial layers of boron nitride could allow high-performance gallium nitride gas sensors to be grown on sapphire substrates and then transferred to metallic or flexible polymer support materials. The technique could facilitate the production of low-cost wearable, mobile and disposable sensing devices for a wide range of environmental applications. Transferring the gallium nitride sensors to metallic foils and flexible polymers doubles their sensitivity to nitrogen dioxide gas, and boosts response time by a factor of six. The simple production steps, based on metal organic vapor phase epitaxy (MOVPE), could also lower the cost of producing the sensors and other optoelectronic devices. Sensors produced with the new process can detect ammonia at parts-per-billion levels and differentiate between nitrogen-contain
