Enhanced Oxidase‐Like Activity of Ag‐Decorated V2O5 Hollow Microspheres for the Colorimetric Detection of Mercury (II) Ions

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this work, we report the synthesis of a novel Ag‐decorated V2O5 nanozyme with intrinsic oxidase‐like activity for the colorimetric detection of Hg2+ ions. The Ag/V2O5 hollow microspheres were synthesized via a simple hydrothermal method followed by Ag nanoparticle decoration and thoroughly characterized by XRD, XPS, SEM, TEM, HRTEM, and EDX.

Structural heterogeneity and permeability in faulted eolian sandstone: Implications for subsurface modeling of faults [PDF]

open access: yes, 2002
We determined the structure and permeability variations of a 4 km-long normal fault by integrating surface mapping with data from five boreholes drilled through the fault (borehole to tens of meters scale).

Eggshell‐Based Biochar for Superior Adsorption of Crystal Violet Dye and Fluoride From Wastewater

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Present study investigates the efficiency of eggshell biochar as a low‐cost and ecofriendly adsorbent for the simultaneous removal of fluoride ions and crystal violet (CV) dye from wastewater. The eggshell waste was pyrolyzed to produce biochar, which was thoroughly characterized and subsequently employed for contaminant adsorption.

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

open access: yesThe Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.
