The ring size effect of macrocyclic TMC ligands in nonheme iron(IV)-oxo complexes has been examined in hydrogen atom transfer (HAT) and oxygen atom transfer (OAT) reactions; an iron(IV)-oxo complex bearing a smaller TMC ligand is more reactive in both HAT and OAT reactions, resulting from its high Fe(IV/III) redox potential.

Invited for this month's cover picture is the group of Professor Toribio F. Otero at the Centre for Electrochemistry, Intelligent Materials and Devices at the Polytechnic University of Cartagena (Spain). The cover picture shows an electrochemical cell as well as three representative cyclic voltammetric responses, displaying the electrolyte potential window, the monomer oxidation-polymerization ...

An experimental method for measurement of local redox potential within multilayer electrodes was developed and applied to all-vanadium redox flow batteries (VRFBs). Through-plane measurement at the positive side reveals several important phenomena including potential distribution, concentration distribution of active species and the predominant reaction location within the porous carbon electro...

African yam bean (Sphenostylis stenocarpa) is an underexploited legume with the potential of becoming an alternative food staple to alleviate the problem of food security. An assessment was carried out on the growth and yield of AYB affected by Telfairia mosaic virus (TeMV) Infection. Telfairia mosaic virus caused severe mosaic, leaf distortion and malformation on AYB. Analyses of results revea...

The aim of this paper is to introduce Reductor, a program that automatically removes unused parts of the source code of valid programs written in the Mercury language. Reductor implements two main kinds of reductions: statical reduction and dynamical reduction. In the statical reduction, Reductor exploits semantic analysis of the Melbourne Mercury Compiler to find routines which can be removed ...

Survival of Treponema pallidum was found to be prolonged in the presence of tissue culture. Of the 12 cultures studied, cottontail rabbit epithelium (Sf1Ep) supported T. pallidum for the longest time. In horizontal Leighton tubes with reduced medium and an atmosphere of 5% CO2 in N2, the 50% survival time (ST50) was 5 to 6 days for treponemes associated with monolayers of Sf1Ep cells. Comparabl...
