“…To date, different types of inorganic photochromic materials have been developed including robust oxides (BaMgSiO 4 , Na ), [43][44][45][46][47][48][49] rare earth (RE) doped compounds (CaF 2 :Ce, CaF 2 :Gd and CaF 2 :Sm, Eu), [50][51][52][53][54][55][56][57][58] transition metal oxides (WO 3 , TiO 2 , V 2 O 5 , Nb 2 O 5 and MoO 3 ), [59][60][61][62][63] and metal halides (AgCl, CuCl). [64,65] Research in these materials mainly focuses on further improving their performance, understanding the mechanism of photochromism as well as exploring new applications. For example, a series of modulation strategies such as engineering the grain to nanoparticles, regulating the defect levels, and using electric field poling have been developed to improve the photochromic contrast.…”

Inorganic photochromic materials, as emerging photoresponsive materials, have attracted unparalleled interest because of their potential applications in various photoactive devices such as smart windows, optical memories, and photochromic decorations. Over the past decades, great research efforts have been focused on further development of high‐performance photochromic materials, revealing the underlying physical mechanism as well as exploring new advanced applications. However, significant challenges still exist in achieving large photochromic contrast, realizing color‐tunable response, and confirming the detailed photochromic processes. In this review, the latest progress of inorganic photochromic materials is summarized from the aspects of the advance of new materials, the mechanism of photochromism, the techniques for evaluating and revealing photochromism, and the methods for regulating photochromic behavior. The emerging applications of photochromic materials for optical information storage, photocatalysis, optical anti‐counterfeiting, radiation dosimetry and so on are also discussed. The perspectives and challenges of photochromic materials in terms of practical applications are presented. This review aims to provide fundamentals about the mechanism, properties and applications of inorganic photochromic materials and promote the application of photochromic materials in various optical devices.

“…Meanwhile, the other corrosion products basic copper chlorides (CuCl 2 •3Cu(OH) 2 ) are often voluminous, which will destroy the surfaces of bronze wares as well as provide an easy path for the entrance of oxygen and humidity [7]. On the other hand, basic copper chlorides themselves could also release Cl − and aggravate the corrosion of the copper matrix [8]. Therefore, the removal of chloride species is an efficient method for inhibiting a self-accelerated corrosion process known as "bronze disease" [9].…”

Archaeological objects based on copper alloys (such as bronze wares) usually suffer from “bronze disease” that results from the existence of CuCl on the surfaces. The surface-coating Cu2(OH)3Cl can release Cl− and lead to further corrosion during the storage procedure. The central aim of the work is the verity the effectiveness of low-temperature radio-frequency (RF) plasma for the removal of CuCl and Cu2(OH)3Cl from the bronze wares. In this work, CuCl and Cu2(OH)3Cl patina were synthesized on copper by a simple solution method. The chemical and aesthetic features before and after plasma treatment were characterized using optical microscopy (OM), SEM-EDS, XRD, and XPS. The results show that Ar-H2 plasma could reduce the CuCl to Cu efficiently, which achieves pleasing esthetics as well as removes the chlorine (Cl atomic ratio decrease from 46.0 to 3.6%). For Cu2(OH)3Cl, the air plasma treatment exhibit better performance compared to the Ar-H2 plasma treatment, judging from the aesthetic effect and the removal effect of chlorine (Cl atomic ratio decrease from 14.8 to 3.3%).

“…At present, the anode current collector of commercial LIBs is mainly electrolytic copper foil, but research on its structure and performance is still lacking [9,10]. The chemical stability of electrolytic copper foil is directly related to whether it can maintain good performance in the electrolyte and repeated charge and discharge environment, which will directly affect the stability of the battery [11][12][13][14]. In addition, during the long-term cycling process, the repeated intercalation and de-intercalation of Li + will inevitably lead to the volume expansion of the graphite anode, thereby reducing the bonding strength between graphite and electrolytic copper foil, increasing the interface impedance, and endangering the cycle life of the battery [15].…”

Improving the interfacial properties between the electrode materials and current collectors plays a significant role in lithium-ion batteries. Here, four kinds of electrolytic copper foils with roughness (Rz) values of 1.2, 1.5, 2.2, and 2.8 μm were prepared via an electropolishing technique. Reducing the roughness of the electrolytic copper foil can effectively improve the wettability of the anode slurry. The electrolytic copper foil with a roughness value of 1.2 μm shows the best coating uniformity of the graphite anode slurry. The battery with this electrolytic copper foil (Rz = 1.2 μm) as the current collector exhibits fifth-cycle capacities of 358.7 and 102.5 mAh g−1 at 0.2 and 3.0 C, respectively, showing excellent rate capability. In addition, at 0.5 C, the battery exhibits an initial discharge capacity of 319.5 mAh g−1 and a 100th-cycle capacity retention rate of 98.1%, demonstrating a high level of cycling performance. These results indicate that reducing the roughness of electrolytic copper foil can provide a feasible route to improve the performance of lithium-ion batteries.
