The colonization of aquatic to terrestrial habitats by brachyuran crabs requires genetic innovations as well as morphological adaptations to adapt to terrestrial environments. The genetic basis of such adaptive evolution, however, is largely unknown. This study focuses on terrestrialization in Geograpsus (Grapsidae) the only highly terrestrial genus in this family, which represents a notable example of terrestrial adaptive radiation.

Only one Cancroidea species of mitogenomes has been sequenced before; in this research, the mitogenomic characteristics of (Cancridae: Cancroidea) are newly studied. The length of the mitogenome was 48,820 bp, and it contained the typical 13 protein-coding genes, 2 ribosomal RNA genes, and 22 transfer RNA genes.

- Ni-doped ZnO nanowire arrays (Ni-ZnO NRs) are created using a hydrothermal method on specialized electrodes, with different nickel concentrations (0-12 at. %) to optimize device performance.
- Scanning electron microscopy and high-resolution transmission electron microscopy are used to analyze the NRs' morphology and structure, revealing that an 8 at. % Ni precursor concentration exhibits superior selectivity and responsiveness for hydrogen sulfide (HS) gas at 250 °C compared to other tested gases.
- The enhanced sensitivity of the Ni-ZnO NRs is attributed to the uniformity of the nanowire array and the presence of doped nickel ions, which increase the surface area for gas adsorption, leading
High Sensing Performance Toward Acetone Vapor Using TiO Flower-Like Nanomaterials.
Nanoscale Res Lett
September 2022
Article Synopsis
- This study focuses on improving gas sensors using nanomaterials, specifically flower-like anatase TiO nanomaterials (FLNMs) for better performance in detecting acetone vapor.
- The TiO FLNMs are created through a one-step hydrothermal method and show high selectivity and response with a response value of 33.72 at 250 ppm acetone and a linear relationship in measurements.
- With a fast response/recovery time of 46/24 seconds and a detection limit of 0.65 ppm, lower than the threshold for diabetes detection (0.8 ppm), these sensors suggest potential for medical diagnostics.
