Data from: Enhancement on the electrochemical properties of commercial coconut shell-based activated carbon by H2O dielectric barrier discharge plasma
Commercial coconut shell-based activated carbon (CSAC) has low specific capacitance and specific capacitance retention owing to its undeveloped pore structure and low proportion of heteroatoms. In this study, dielectric barrier discharge (DBD) plasma was used to enhance the specific capacitance and rate capability of CSAC. H2O was used as excited medium to introduce oxygen functional groups. The physicochemical properties of CSAC and CSAC modified by H2O plasma (HCSAC) were revealed by automated surface area and pore size analysis, Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy (Raman). Electrochemical workstation was applied to investigate the electrochemical properties of CSAC and HCSAC. Obtained results showed that plasma modification improved the specific capacitance of CSAC by 64.8% (current density, 1 A g-1; electrolyte, 6 M KOH solution) within 100 seconds. This result is ascribed to the oxygen functional groups introduced to the surface of CSAC. It can also improve hydrophilicity and wettability of the carbon surface leading to an increase from 76.7% to 84.6% in specific capacitance retention. Furthermore, H2O plasma modification can introduce oxygen functional groups without destroying the initial pore structures of CSAC. In summary, we provide a simple, fast, environment-friendly modification method to enhance the electrochemical properties of CSAC.

Shell shape and environmental data for five North American land snail species
<p>The morphological distinctness of land snail shells is almost certainly related to the unique environments in which they live. Even with the development of genetic and epigenetic tools for understanding factors contributing to phenotype, much research is focused on understanding environmental effects on land snail shell form. Most studies focus on single taxa, with review articles summarizing shared patterns and correlations of shell response to the environment. Herein we provide a dataset of shell shapes and environmental data for five species of partially sympatric North American land snail. Data are sourced from museum specimens, invaluable resources for biological and biodiversity information. We imaged, landmarked, georeferenced, and extracted environmental parameters for 3,701 land snail specimens representing five North American land snail species: <em>Anguispira alternata</em>, <em>Euglandina rosea</em>, <em>Haplotrema concavum</em>, <em>Mesodon thyroidus</em>, and <em>Mesomphix globosus</em>. These specimens represent most of the primary dry holdings for the five species at the Florida Museum of Natural History, Gainesville, Florida, USA. The landmark and environmental data are provided in formats (TPS and CSV respectively) compatible with modern methods of analyzing and interpreting geometric morphometric data.</p>

Pre-Columbian Shell Cup, Seminole County, FL
This shell cup was made from a large lightning whelk and is still partially embedded in concreted shell midden. It dates to the preceramic Late Archaic period (ca. 5700-4600 BP) and was recovered from Panther Tracks, a pre-Columbian indigenous site in Seminole County, Florida. The artifact is currently curated at the Rollins College Archaeology Lab. Model by Ellie Minette. Source: Objaverse 1.0 / Sketchfab

Shell Adze, Orange County, Florida
This adze is a woodworking tool made from the whorl of a queen conch (Strombus gigas) shell imported from the coast.
