TL;DR: The most promising sources of salt tolerance were identified in S. commersonii and S. multidissectum and information obtained is discussed from a breeding perspective as discussed by the authors , and a significant correlation between root plasticity and salt tolerance was found, and changes in proline and total phenolic content were assessed to envisage the metabolic adjustments of tolerant clones towards salinity.

TL;DR: In this paper, an electro-optic Si-based modulator working at 1.5 um using a bipolar mode field effect transistor integrated within a Si rib waveguide is presented.

TL;DR: In this paper, the performance of different configurations of a-Si:H-based electro-optical amplitude modulators integrated into passive waveguides is discussed. But the authors focus on the plasma dispersion effect, a phenomenon that allows to reach useful performances at the communication wavelengths of λ~1.55 μm.

TL;DR: In this article, the photoluminescence signal emitted by graphene oxide (GO) nanosheets infiltrated in silanized porous silicon (PSi) matrix was investigated, and a strong enhancement of the PL emitted from GO by a factor of almost 2.5 with respect to GO on crystalline silicon was experimentally measured.

TL;DR: In this paper, an optical phase mask with an electrooptically tunable phase step is used for photolithographic experiments. But the phase mask consists of a 2-dimensional hexagonal lattice of inverted ferroelectric domains fabricated on a z-cut lithium niobate substrate and the phase step, between inverted domain, is obtained by the application of an external electric field along the z axis of the crystal via transparent electrodes.
