TL;DR: In this article, the authors studied the fracture resistance of amorphous silicon micropillars (∼2.3mm tall) after electrochemical lithiation and delithiation.

TL;DR: Nanoporous silicon (Si) networks with controllable porosity and thickness are fabricated by a simple and scalable electrochemical process, and then released from Si wafers and transferred to flexible and conductive substrates to serve as high performance Li-ion battery electrodes.

TL;DR: In this article, a polycrystalline metal-organic framework (MOF) was synthesized on surface modified silicon nanowires (SiNWs) by matching of the SiNW surface functional groups with the MOF organic linker coordinating groups.

TL;DR: In this article, a microscopic model is presented to describe the size-dependent fracture of crystalline Si nanopillars (NPs) during lithiation, where the initial size and spacing of the nanovoids, together with the computed facture toughness, are chosen to conform to recent experiments which showed the critical diameter of Si NPs to be 300-400nm.

TL;DR: Experimental results with both simulated images and real SAR images demonstrate that the proposed method achieves state-of-the-art despeckling performance in terms of peak signal-to-noise ratio (PSNR), structural similarity (SSIM) index, equivalent number of looks (ENLs), and ratio image.
