Article Abstract
Rechargeable aqueous Zn-ion batteries (ZIBs) are considered as a new energy storage device for wearable electronic equipment. Nowadays, dendrite growth and uneven deposition of zinc have been the principal problems to suppress the development of high-performance wearable zinc-ion batteries. Herein, a perovskite material of LaAlO nanoparticle has been applied for interface engineering and zinc anode protection. By adjusting transport channels and accelerating the Zn diffusion, the hydrogen evolution reaction potential is improved, and electric field distribution on the Zn electrode surface is regulated to navigate the fast and uniform deposition of Zn. As a proof of demonstration, the assembled LAO@Zn||MnO batteries can display the highest capacity of up to 140 mAh g without noticeable decay even after 1000 cycles. Moreover, a motor-driven fan and electronic wristwatch powered by wearable ZIBs can demonstrate the practical feasibility of LAO@Zn||MnO in wearable electronic equipment.

Pancreatic neuroendocrine tumors (PanNETs) are a heterogeneous group of neoplasms that include tumors with different histomorphologic characteristics that can be correlated to sub-categories with different prognoses. In addition to the WHO grading scheme based on tumor proliferative activity, a new parameter based on the scoring of infiltration patterns at the interface of tumor and non-neoplastic parenchyma (tumor-NNP interface) has recently been proposed for PanNET categorization. Despite the known correlations, these categorizations can still be problematic due to the need for human judgment, which may involve intra- and inter-observer variability.

Background: One of the key functions of human skin is to provide a barrier, protecting the body from the surrounding environment and maintaining homeostasis of the internal environment. A mature, stratified epidermis is critical to achieve skin barrier function and is particularly important when producing skin grafts in vitro for wound treatment. For decades epidermal stratification has been achieved in vitro by culturing keratinocytes at an air-liquid interface, triggering proliferating basal keratinocytes to differentiate and form all epidermal layers.

A reasonable construction of hollow structures to obtain high-performance absorbers is widely studied, but it is still a challenge to select suitable materials to improve the low-frequency attenuation performance. Here, the FeO@C@NiO nanoprisms with unique tip shapes, asymmetric multi-path hollow cavity, and core-shell heteroepitaxy structure are designed and synthesized based on anisotropy and intrinsic physical characteristics. Impressively, by changing the load of NiO, the composites achieve strong absorption, broadband, low-frequency absorption: the reflection loss of -55.

The development of aqueous zinc metal batteries (AZMBs) is hampered by dendrites and side reactions induced by reactive HO. In this study, a hydrated eutectic electrolyte with restrictive water consisting of zinc trifluoromethanesulfonate (Zn(OTf)), 1,3-propanediol (PDO), and water is developed to improve the stability of the anode/electrolyte interface in AZMBs via the formation of a water-deficient interface. Additionally, PDO participates in the Zn solvation structure and inhibits the movement of water molecules.
