The reactivity of six MnIV-oxo complexes in C-H bond oxidation has been examined using a combination of kinetic experiments and computational methods. Variable-temperature studies of the oxidation of 9,10-dihydroanthracene (DHA) and ethylbenzene by these MnIV-oxo complexes yielded activation parameters suitable for evaluating electronic structure computations. Complementary kinetic experiments of
The affinity of AMD3100, a symmetrical nonpeptide antagonist composed of two 1,4,8,11-tetraazacyclotetradecane (cyclam) rings connected through a 1,4-dimethylene(phenylene) linker to the CXCR4 chemokine receptor was increased 7, 36, and 50-fold, respectively, by incorporation of the following: Cu2+, Zn2+, or Ni2+ into the cyclam rings of the compound. The rank order of the transition metal ions co
Absorption and fluorescence spectral properties of J-aggregates of core-tetrasubstituted perylene bisimide (PBI) dyes have been investigated in the temperature range from 300 to 5 K. A special feature of the present PBI J-aggregates is that, in contrast to classical J-aggregates like that of pseudoisocyanine (PIC), the chromophores are held together not only by van-der-Waals interactions but also
The study of direct electron transfer between enzymes and electrodes is frequently hampered by the small fraction of adsorbed proteins that remains electrochemically active. Here, we outline a strategy to overcome this limitation, which is based on a hierarchical analysis of steady-state electrocatalytic currents and the adoption of the "binary activity" hypothesis. The procedure is illustrated by
In 2021, neutron structures of oxidised and reduced human manganese superoxide dismutase were published, suggesting several unexpected features, including deprotonated glutamate, tyrosine and histidine residues and a reduced Mn ion with two hydroxide ligands. We have used quantum refinement to evaluate whether alternative interpretations of the structures are possible, comparing many structural mo
Anion exchange membrane water electrolysis (AEMWE) has a great potential to be established as a high-performance and low-capital cost technology for hydrogen production. High current densities can be achieved with non-platinum group metal (non-PGM) catalyst. However, the harsh operation conditions require stable cell components. Here, we report on the use of a highly stable and ion conductive poly
The objective of this paper is to outline and discuss the key elements of an EU industrial development policy consistent with the Paris Agreement. We also assess the current EU Industrial Strategy proposal against these elements. The “well below 2 °C” target sets a clear limit for future global greenhouse gas emissions and thus strict boundaries for the development of future material demand, indus
Hydrogen atom transfer (HAT) reactions by high-valent metal-oxo intermediates are important in both biological and synthetic systems. While the HAT reactivity of FeIV-oxo adducts has been extensively investigated, studies of analogous MnIV-oxo systems are less common. There are several recent reports of MnIV-oxo complexes, supported by neutral pentadentate ligands, capable of cleaving strong C-H b
Defects at the interface between InAs and a native or high permittivity oxide layer are one of the main challenges for realizing III-V semiconductor based metal oxide semiconductor structures with superior device performance. Here we passivate the InAs(100) substrate by removing the native oxide via annealing in ultra-high vacuum (UHV) under a flux of atomic hydrogen and growing a stoichiometry co
Treated bamboo can be made into large, durable structural elements which have the potential to become a transformative large-scale building material, but the fracture behaviour which determines their ultimate strength in various loading scenarios has not been studied. Laminated bamboo is a promising structural engineered bamboo material, and is generally made from bamboo treated to improve its dur
Hydrogen in a hexapole collision cell is used with varying success in multi-collector Inductively Coupled Plasma Mass Spectrometry to reduce the plasma derived interferences 40Ar16O+ and 40Ar16OH+ that are isobaric with 56Fe+ and 57Fe+ respectively. The reactions of ArO+ and ArOH+ with H2 in the hexapole of a multi-collector Inductively Coupled Plasma Mass Spectrometer were studied practically and
ESSνSB is a design study for a next-generation long-baseline neutrino experiment that aims at the precise measurement of the CP-violating phase, δCP, in the leptonic sector at the second oscillation maximum. The conceptual design report published from the first phase of the project showed that after 10 years of data taking, more than 70% of the possible δCP range will be covered with 5σ C.L. to re
The intricate relationship between climate change and the building sector is characterized by a self-reinforcing loop. Rising temperatures driven by global warming will inevitably impact heating and cooling energy, while buildings simultaneously contribute significantly to carbon emissions throughout their lifecycle, further exacerbating climate change. However, current knowledge regarding the int
The increasing global demand for sustainable energy has sparked interest in combining renewable technologies to leverage their synergies. This thesis presents a pre-feasibility study of a combined offshore wind and wave energy farm located off the coast of Galicia, Spain. In collaboration with Wavepiston, a Danish developer of wave energy converters (WECs), the study evaluates the integration of t
Two major fuels commonly used in compression ignition (CI) and spark ignition (SI) enginesare diesel and gasoline. The reserve of diesel and gasoline is limited, however the combustion ofthese fuels giving rise to air pollution. This calls for the search for alternative fuels, preferablyrenewable fuels, and the development of more efficient and clean combustion technologies forinternal combustion

Solar energy ~10 000 times today’s total global energy consumption impinges on Earth. Could we only convert a small fraction of all this energy to useful energy forms, our future energy supply is secured. Photovoltaics converts light to electricity and NW technologies have the potential to provide multi-bandgap materials otherwise not feasible and low material-consumption devices. Nanowire array
