The B-type Channel Is a Major Route for Iron Entry into the Ferroxidase Center and Central Cavity of Bacterioferritin
Bacterioferritin is a bacterial iron storage and detoxification protein that is capable of forming a ferric oxyhydroxide mineral core within its central cavity. To do this, iron must traverse the bacterioferritin protein shell, which is expected to occur through one or more of the channels through the shell identified…
Desulfurization of gasoline using novel mesoporous carbon adsorbents
Ordered mesoporous carbon (OMC) adsorbents have been prepared using spherical SBA-16 mesoporous silica, as a template. The synthesized materials were studied by X-ray diffraction, scanning electron microscopy and nitrogen adsorption–desorption isotherms. OMCs have been tested for adsorption of dibenzothiophene (DBT) a…
Developments in packaging of fresh fruits- shelf life perspective: A review
The demand for high quality fruits is increasing owing to their numerous health benefits. However, the fruit quality is a key concern for the consumers; packaging is one of the viable options to extend the shelf life of fresh fruits. Several factors like temperature, oxygen, cultivar, handling, ethylene and respiratio…
Fabrication of New 2.4 V Lithium‐Ion Cell with Carbon‐Coated LiTi2(PO4)3 as the Cathode
Abstract In the present work, we present the successful fabrication of a 2.4 V Li‐ion cells with NASICON‐type carbon‐coated LiTi2(PO4)3 [C‐LiTi2(PO4)3] as the cathode and pre‐lithiated graphite (LiC6) as the anode . This class of 2.4 V Li‐ion cell, C‐LiTi2(PO4)3/LiC6, is capable of delivering charge and discharge capa…
The Formal Oxidation States of Iridium Now Run from −III to +IX
Rarer than a new element: Recently Wang et al. produced the [(Ir+IX)O4]+ ion by a pulsed laser vaporization/thermal expansion method and studied it by IR photodissociation spectroscopy. The oxidation state of +IX had been unknown previously. The picture shows the mass spectra for the argon-tagged iridium oxide species.
Hydrogen generation and degradation of trypan blue using fern-like structured silver-doped TiO 2 nanoparticles
TiO 2 :Ag nanoparticles have been prepared using an ionic liquid assisted hydrothermal method, which generate 2230 μmol g −1 of hydrogen in 2.5 h.
Thermal and plasma enhanced atomic layer deposition of TiO2: Comparison of spectroscopic and electric properties
Titanium oxide (TiO2) deposited by atomic layer deposition (ALD) is used as a protective layer in photocatalytic water splitting system as well as a dielectric in resistive memory switching. The way ALD is performed (thermally or plasma-assisted) may change the growth rate as well as the electronic properties of the d…
A self-assembled triphenylamine-based fluorescent chemosensor for selective detection of Fe 3+ and Cu 2+ ions in aqueous solution
Triphenylamine-based fluorescent chemosensor m -TAPA (S) shows high selectivity and sensitivity toward Fe 3+ /Cu 2+ in natural and drinking water. Additionally, the TCL strips serve as a simple method for detection of Fe 3+ /Cu 2+ at the nanomolar range.
Switchable platinum-based tweezers with Pt–Pt bonding and selective luminescence quenching
Molecular tweezers incorporating peripheral platinum salphen complexes and a central chelating terpyridine group have been synthesized. The terpyridine can be switched upon metal binding between a free 'W' shaped form and a coordinated 'U' form. The crystallographic structure of the zinc-closed molecular tweezers was…
Design of vanadium oxide core–shell nanoplatelets for lithium ion storage
We designed and synthesized V 2 O 3 nanoplatelets@carbon and V 2 O 5 nanoplateletes@TiO 2 core–shell structures with superior electrochemical performance compared to their non-coated counterparts.
Compact Coupled Graphene and Porous Polyaryltriazine‐Derived Frameworks as High Performance Cathodes for Lithium‐Ion Batteries
Abstract It is highly desirable to develop electroactive organic materials and their derivatives as green alternatives of cathodes for sustainable and cost‐effective lithium‐ion batteries (LIBs) in energy storage fields. Herein, compact two‐dimensional coupled graphene and porous polyaryltriazine‐derived frameworks wi…
