Abstract Since the first realization of two-photon direct laser writing (DLW) in Maruo et al. (Opt Lett 22:132–134, 1997), manufacturing using techniques spread out many laboratories all over world. Photosensitive materials with different material properties open a new field for micro- and nanofabrication. The achievable structuring resolution this technique is reported to be sub-100 nm (Paz J....

Layered semiconductors based on transition-metal chalcogenides usually cross from indirect bandgap in the bulk limit over to direct bandgap in the quantum (2D) limit. Such a crossover can be achieved by peeling off a multilayer sample to a single layer. For exploration of physical behavior and device applications, it is much desired to reversibly modulate such crossover in a multilayer sample. ...

compost is a gradual process in nature by which organic materials are decomposed in the presence of air by microorganisms and fungi. the product is a valuable fertilizer that is used in different places even in home little gardens, so that it has signed as an unnoticed asset. with due attention to the importance of compost, its guidelines and standards should be evaluated. it is pointed and com...

In conventional direct torque control (DTC) of induction machines, undesirable flux and torque ripples are produced. These occur since non of the selected inverter's voltage vectors are able to generate the exact voltage required to produce the desired changes in the electromagnetic torque and stator flux linkage in most of the switching instances. In addition, when direct torque control is imp...
