“…The surface areas of pBZn and ZnTCF@Sn were quantitatively compared using confocal laser scanning microscopy (CLSM) and the corresponding ratio of the increment in the interfacial area ( A i ) to the projected area ( A p ) (denoted as Sdr (%)) (Figure S18, Supporting Information). [ 40 ] The Sdr value of ZnTCF@Sn (64.0%), which is more than sixfold higher than that of pBZn (10.1%), indicates that ZnTCF@Sn can provide more electrochemically active zincophilic nucleation sites for Zn 2+ . As evidenced by this, the cyclic voltammetry (CV) curve of the ZnTCF@Sn asymmetric cell (ZnTCF@Sn/stainless steel (SS)) shows an approximately nine times larger electrochemical active area than that of the pBZn/SS cell (Figure S19, Supporting Information).…”

Zn metal anodes (ZMAs) undergo irregular deposition and unfavorable side‐reactions, which hinder the practical application of aqueous rechargeable Zn metal batteries (ARZMBs). Chemical replacement reaction (CRR) strategies can achieve stable ZMAs, but the effect of the crystal facets of metallic Zn as reductants remains poorly understood. In this study, based on the observation that preferentially exposed Zn crystal facets affect the surface characteristics of chemically replaced layers in Sn‐based CRR, a multifunctional Sn‐based interfacial layer (ZnTCF@Sn) is designed on the Zn with a textured crystal facets using a novel 2‐step CRR process. ZnTCF@Sn simultaneously provides abundant zincophilic sites and high surface energy and homogenizes the distribution of current/Zn2+ flux, resulting in fast electrochemical kinetics and dendrite‐free deposition. Furthermore, the uniform Sn coverage on the ZnTCF@Sn surface inhibits side‐reactions and enhances reversibility during Zn deposition/dissolution. Thus, the ZnTCF@Sn achieves exceptional cyclability over 1200 h even under harsh operating conditions with a cumulative capacity of 24 Ah cm–2. This study contributes to the development of practical ARZMBs by providing new insights into the effect of the Zn crystal facets on the surface modification of ZMAs through various CRRs.This article is protected by copyright.

“…Chao Lu et al [13] designed a quadrant detector by quadrant photodiode for estimating the laser beam position. The method used by other researchers to measure the beam size is to place the photodiode or other sensors behind the knife-edge and analyze the size of the laser by receiving the signal behind the knife-edge [14][15][16][17][18][19][20]. Our beam profiling system experimental equipment used laser diode package to measure the laser beam size based on the self-mixing interference.…”

Laser is widely used in industry, biomedical and other kinds of fields. Beam size is the most important parameter among the laser variables. Typical state-of-the-art profiling techniques employ either a scanning-based or camera-based system, using photodiodes or image sensors as the signal receiver. Despite their profiling capabilities, these systems do not tend to be budget-friendly and easy to operate. In this paper, a novel cost-effective beam profiling prototype based on self-mixing interference was developed to measure the Full Width Half Maximum (FWHM) of a range of laser diodes by the knifeedge approach. The difference between our prototype and other systems is that the photodiode is placed behind the laser source, and beam size is calculated by analyzing the feedback signal. A commercial camera beam profiler was used to benchmark our prototype. Results show that though there is a variation of 45.29% between the measured beam size and the integrated beam size in the x directions due to diffuse and specular reflection, our USD 200 prototype has a high accuracy on the prediction of laser beam sizes. Our prototype could provide accurate predicted beam size for Gaussianalike beam. This is the very first study to explore the application of self-mixing interference in laser beam profiling. It is believed that our proposed approach has contributed to the on-going development of laser beam profiling methodology.
