The efficient and low-cost adsorption of arsenic toxins from drinking water is a global concern because of its adverse health effects. The simple extraction and eco-friendly environmental waste management of arsenic(V) species using hierarchy rutile TiO 2 were reported. Mesoporous microscale TiO 2 sphere 3D monoliths were successfully fabricated with uniform mesopores morphology-like blobfish head containing open nanoscale eyes through hydrothermal one-pot synthesis. The blobfish head TiO 2 (BHT) was mainly oriented along the predominant {110} facet and with dense top-surface atomic Ti 4+ and O 2− sites along the crystal edge surface and central crystals. These characteristics lead to efficient adsorption and selective binding to As(V) species in acidic medium. The photoinduced irradiation of the BHT adsorbent promoted significant trapping and high adsorptivity, with a maximum capacity reaching 125 mg/g from drinking water. The BHT adsorbent selectively binds As(V) species among competitive anions, such as chlorides, bicarbonates, and sulfates, as well as cations, such as Ca 2+ , Mg 2+ , Co 2+ , Al 3+ , Ni 2+ , Cd 2+ , Mn 2+ , and Fe 3+ cations, in real samples. Results indicated that the BHT hierarchy can be cycled several times without deteriorating in its significant performances despite the severe treatment under irradiation or chemical treatment agents. The BHT monoliths might be an effective photoadsorbent for final disposals, particularly at low levels of As(V) species in real water sources.
The controlled design of hierarchical CN-ST flowers is a key feature for creating biosensor surface electrodes for photo-electrochemical, ultrasensitive screening of mono-bioactive molecules.
We report on low-cost fabrication and high-energy density of full-cell lithium-ion battery (LIB) models. Super-hierarchical electrode architectures of Li2SiO3/TiO2@nano-carbon anode (LSO.TO@nano-C) and high-voltage olivine LiMnPO4@nano-carbon cathode (LMPO@nano-C) are designed for half- and full-system LIB-CR2032 coin cell models. On the basis of primary architecture-power-driven LIB geometrics, the structure keys including three-dimensional (3D) modeling superhierarchy, multiscale micro/nano architectures and anisotropic surface heterogeneity affect the buildup design of anode/cathode LIB electrodes. Such hierarchical electrode surface topologies enable continuous in-/out-flow rates and fast transport pathways of Li+-ions during charge/discharge cycles. The stacked layer configurations of pouch LIB-types lead to excellent charge/discharge rate, and energy density of 237.6 Wh kg−1. As the most promising LIB-configurations, the high specific energy density of hierarchical pouch battery systems may improve energy storage for long-driving range of electric vehicles. Indeed, the anisotropic alignments of hierarchical electrode architectures in the large-scale LIBs provide proof of excellent capacity storage and outstanding durability and cyclability. The full-system LIB-CR2032 coin cell models maintain high specific capacity of ∼89.8% within a long-term life period of 2000 cycles, and average Coulombic efficiency of 99.8% at 1C rate for future configuration of LIB manufacturing and commercialization challenges.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
