We report Electron Paramagnetic Resonance measurements on single crystalline and powder samples of Nd0.5Ca0.5MnO3 across the charge-ordering transition at Tco = 240K down to the antiferromagnetic ordering transition at TN = 140K. The changes in the linewidth, g-factor and intensity as functions of temperature are studied to understand the nature of spin-dynamics in the system. We explain the ob...

From the viewpoint of service operators the Total Cost of Ownership (TCO) for developing a communication service comprises from two parts; CAPital EXpenditure (CAPEX) and OPerational EXpenditure (OPEX). These two types of costs are interrelated and affect any service provider’s deployment strategy. In many traditional methods, selection of critical elements of a new service is performed in a he...

The living ring-opening metathesis polymerization (ROMP) of trans-cyclooctene (tCO) was investigated. ROMP of tCO in the presence of PPh(3) in THF leads to the formation of narrowly dispersed polycyclooctene (PCO). The presence of PPh(3) as an additive and the use of THF as a solvent were demonstrated to be necessary to suppress competing secondary metathesis processes in the ROMP of tCO. Under...

A convenient strategy to radiolabel a hydrazinonicotonic acid (HYNIC)-derived tetrazine with 99mTc was developed, and its utility for creating probes to image bone metabolism and bacterial infection using both active and pretargeting strategies was demonstrated. The 99mTc-labelled HYNIC-tetrazine was synthesized in 75% yield and exhibited high stability in vitro and in vivo. A trans-cyclooctene...

Transparent conductive oxide (TCO) thin films were removed from glass substrates using femtosecond laser pulses. Irradiating through the glass, the threshold for complete TCO ablation was much lower than for front-side irradiation. Additionally, the former method created almost rectangular crosssectional groove profiles despite the Gaussian laser beam. This indicates a non-thermal ultrafast abl...

Metabolic acidosis frequently complicates end-stage renal failure. In haemodialysis patients its severity is usually monitored by measurement of the total CO(2) (TCO(2)) level. Samples from 'satellite dialysis' patients are often stored prior to analysis. We investigated the affect of storage of 21 samples for 24 h under different conditions prior to analysis. If samples were stored at room tem...

We report the first electron paramagnetic resonance studies of single crystals and powders of Pr0.6Ca0.4MnO3 in the 300-4.2 K range, covering the charge ordering transition at ∼ 240 K and antiferromagnetic transition (TN ) at ∼ 170 K. The asymmetry parameter for the Dysonian single crystal spectra shows anomalous increase at Tco. Below Tco the g-value increases continuously, suggesting a gradua...

Nowadays, the industrial competition is based on the Total Cost Ownership of the products (TCO). This is particularly true for big complex systems such as helicopters, for which the maintenance costs, often takes the largest part of this TCO. Thus the challenge for such integrators is to invest in reliability engineering projects aimed at increasing their product’s reliability to market them wi...

The interplay of surface texture, strain relaxation, absorbance, grain size, and sheet resistance in textured, boron-doped ZnO (ZnO@B), transparent conductive oxide (TCO) materials of different thicknesses used for thin film, solar cell applications is investigated. The residual strain induced by the lattice mismatch and the difference in the thermal expansion coefficient for thicker ZnO@B is r...
