TL;DR: In this paper, a two-dimensional photonic crystal slabs in silicon-on-insulator platforms are used for channel drop filters for dense wavelength division multiplexing systems.

TL;DR: In this article, a flexible and wearable dry electrode technology based on polydimethylsiloxane (PDMS) is presented, which has been tested for EMG and ECG signal acquisition as the proof of principle.

TL;DR: J-V curves of the fabricated ZnO nanowire-based mercurochrome-sensitized solar cells indicated that the short-circuit current density is increased with increasing the length of the nanowires, and according to the UV-vis spectra of the dyes detached from the cells, these increments were mainly attributed to the enlarged internal surface area and therefore dye loading enhancement in the lengthenednanowire arrays.

TL;DR: The modified homotopy perturbation method (HPM), incorporating He’s polynomial into the HPM, combined with the Fourier transform, is used to solve the nonlinear and singular Lane–Emden equations.

TL;DR: Experimental results present that the proposed fuzzy techniques result in increasing of power delivery from the solar panel, causing a reduction in size, weight, and cost of solar panels in photovoltaic systems.
