“…The Zn anode cycled in the Ar-purged electrolyte show similar peaks with the anode in the blank electrolyte, both evidencing the existence of side products. After cycling in the CO 2 -purged electrolyte, zinc foil shows FTIR peaks at 1450 and 1380 cm –1 correspond to the out-of-plane bending of CO 3 2– , bands at 700–1100 cm –1 correspond to the lattice vibration of CO 3 2– , and peaks at 960 cm –1 , 890 cm –1 , 830 cm –1 , and 700 cm –1 correspond to the bending vibration of O–C–O (Figure c). − All the absorption peaks on the FTIR spectrum matched well with ZnCO 3 , evidencing the existence of a ZnCO 3 protection layer on the Zn anode cycled in the CO 2 -purged electrolyte. The results of Raman spectroscopy are consistent with those from FTIR.…”

“…As shown in Figure a, the STEM images revealed the protection layer formed between the Zn surface and the Pt/C coating.

Ultrastable Zinc Anode Enabled by CO₂-Induced Interface Layer

Aqueous Zn-ion batteries (AZIBs), being safe, inexpensive, and pollution-free, are a promising candidate for future large-scale sustainable energy storage. However, in a conventional AZIBs setup, the Zn metal anode suffers oxidative corrosion, side reactions with electrolytes, disordered dendrite growth during operation, and consequently low efficiency and short lifespan. In this work, we discover that purging CO2 gas into the electrolyte could address these issues by eliminating dissolved O2, inhibiting side reactions by buffering the local pH change, and preventing dendrite growth by inducing the in situ formation of a ZnCO3 solid electrolyte interphase layer. Moreover, the CO2-purged electrolyte could enable a highly reversible plating/stripping behavior with a high Coulombic efficiency of 99.97% and an ultralong lifespan of 32,000 cycles (1600 h) even under an ultrahigh current density of 40 mA cm–2. Consequently, the CO2-purged symmetrical cells deliver long cycling stability at a high depth of discharge of 57%, while the CO2-purged Zn/V2O5 full cells exhibit outstanding capacity retention of 66% after 1000 cycles at a high current density of 5 A g–1. Our strategy, the simple introduction of CO2 gas into the electrolyte, could effectively mediate the zinc anode’s critical issues and provide a scalable and cost-effective pathway for the commercialization of AZIBs.

“…In A, three modes are recognizable at 1075, 1082, and 1091 cm –1 , in addition to 1086 cm –1 (aragonite) (Figure b). In light of previous studies − in combination with the elemental compositions determined by μ-XRF imaging above, the emergence of the modes 183, 288, 719, and 1082 cm –1 should be related to the presence of Mn; 194, 303, 729, and 1091 cm –1 to Zn or 741 and 1091 cm –1 to Fe; and 1075 cm –1 to Ba. If Mn, Zn, Fe, or Ba is present as an independent carbonate mineral of rhodochrosite MnCO 3 , smithsonite ZnCO 3 , siderite FeCO 3 , or witherite BaCO 3 in the nacre, then the Mn, Zn, Fe, or Ba map (Figure ) should agree with the spatially resolved intensity of the 1082, 1091, or 1075 cm –1 mode.…”

Nacre of shells and pearls is a common biomineral produced by mollusks, containing a variety of trace elements. Little attention has been paid on the mechanisms of trace element uptake into nacre and its influence on the microstructure of nacre. This knowledge, however, is a prerequisite for our understanding of nacre biomineralization and holds implications for pearl cultivating technology, ecological environment, and materials sciences. Here, we give serious consideration on nacre with an abnormal microstructure of Edison pearls, discovering correlations between the trace element concentrations and the morphology and microstructure of the nacre. Edison pearls are a new breed of freshwater nucleated pearls. The scanning electron microscopy images show that the abnormal area in the nacre has a brick-and-mortar structure as the normal nacre, in which aragonite platelets alternate with organic materials. However, the aragonite platelets vary widely in thicknesses, littered with microcrystal cracks, and present clear color contrasts and a rugged surface. Much higher counts of trace elements are detected such as Mn, Fe, Zn, and Ba in the abnormal nacre, using synchrotron radiation micro-X-ray fluorescence imaging. The abnormal nacre exhibits Raman mode characteristic of multiple carbonate minerals, which suggests that these trace elements substitute for Ca in the aragonite lattice and distort the crystal lattice. In comparison with the peripheral normal nacre, there are lower concentrations of organic materials in the abnormal nacre and that may contribute to the formation of transversal and orthogonal platelet cracks. As a result, the abnormal nacre has a loose coupling structure. Formation of abnormal nacre has individual difference, and it is hypothesized that the metabolic abnormalities of visceral mass after operation procedure results in excessive uptake of trace elements and the consequent formation of abnormal nacre.

“…In the realm of developing new materials for fingerprint development, the combination of organic and inorganic compounds offers an effective affinity for substances commonly found in fingerprints, as highlighted by Da Rosa et al (2023). ZnCO 3 , for example, is a natural crystal with high chemical stability in the air and is notable for its wide applications in optical, physical, and chemical fields [27]. It is known for having small particles, good adhesion, and the ability to reveal clear fingerprints on dark-colored items [1].…”

Fingerprints are essential for human identification and are valuable tools in criminal investigations. The pursuit of new materials for digital printing is expanding, with increasing interest in natural compounds such as bixin, sourced from annatto seeds. Despite its traditional use as a natural dye with medicinal properties, the potential of bixin in papilloscopy remains largely untapped. In this study, we meticulously extracted bixin from annatto seeds and meticulously developed composites incorporating zinc carbonate (bixin/ZnCO3) and kaolinite (bixin/kaolinite). UV-visible spectroscopy was used for characterization, and the extracted bixin showed absorption peaks at 429, 453, and 481 nm, which were very similar to standard peaks at 429, 457, and 487 nm. The two samples also had the same retention times (7.07 min) according to further liquid chromatography analysis. Sweat pores were easier to detect thanks to the effectiveness of the bixin/ZnCO3 and bixin/kaolinite composites in creating high contrast sebaceous and natural latent fingerprints. These results highlight the composites’ potential as novel and fascinating instruments for papilloscopy applications, which might also improve forensic investigations.
