We present a collision model for the charging of quantum battery by identical nonequilibrium qubit units. When units are prepared in mixture energy eigenstates, gain can be described classical random walk, where both average and variance grow linearly with time. Conversely, when qubits contain coherence, interference effects buildup lead to faster spreading distribution, reminiscent walk. This ...

Researchers have proposed and tested a new method that could speed up bioprinting, promising technique for fabricating organs transplants.

The present work examines leaching of lipoxygenase-1 from soybean flour employing stirred tank vessel. The effect of operating parameters, impellers speed, operational period, temperature, pH and scale-up were considered.The acetic acid pH: 5.2 increased the leaching of lipoxygenase- 1.The sensitivity of agitator speed and geometrical-scale-up on the enzymeleaching has bee...
