The Heliospheric Imager (HI) is part of the SECCHI suite of instruments on-board the two STEREO spacecrafts to be launched in 2006. Located on two different orbits, the two HI instruments will provide stereographic images of solar coronal plasma and coronal mass ejections (CME) over a wide field of view (~90°), ranging from 13 to 330 solar radii (R[SUB]0[/SUB]). These observations complete the 15 R[SUB]0[/SUB] field of view of the solar corona obtained with the other SECCHI instruments (2 coronagraphs and an EUV imager). The HI instrument is a combination of 2 refractive optical systems with 2 different multi-vanes baffle system. The key challenge of the instrument design is the rejection of the solar disk light, with total straylight attenuation of the order of 10[SUP]-13[/SUP] to 10[SUP]-15[/SUP]. The optics and baffles have been specifically designed to reach the required rejection. This paper presents the SECCHI/HI opto-mechanical design, with the achieved performances. A test program has been run on one flight unit, including vacuum straylight verification test, thermo-optical performance test and co-alignment test. The results are presented and compared with the initial specifications. [less ▲]

The use of bone scaffolds for treatment of large bone defects could be a solution for many disadvantages which are present with traditional care methods. The success of these scaffolds depends on its internal structure and mechanical properties. To be able to conduct a reliable investigation on the effect of these parameters, an efficient production method is required which can produce controlled internal structures. The presented work examines the ability to produce Ti6Al4V bone scaffolds with selective laser melting. The bone scaffolds were produced with a pore size range of 400-900 mu m and beam size 200 mu m. To check the repeatability mechanical and geometrical tests were performed. [less ▲]

We report evidence for the electrochemical performances of two Li-ion full cells, built up by the combination of LiCo2/3Ni1/6Mn1/6O2 cathode material with MnSn2 intermetallic and Li4Ti5O12 spinel as the anode materials, respectively. MnSn2 and Li4Ti5O12 electrode materials illustrate different working voltage versus the redox couple Li+/Li0 and different reactionmechanisms during lithiuminsertion/deinsertion cycles. The structure,morphological characteristics and the electrochemical properties of the studied materialswere investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and electrochemical techniques. The two full-cell configurations showed different electrochemical behaviors. The MnSn2//LiCo2/3Ni1/6Mn1/6O2 configuration exhibits high working voltage (~3.5 V) and specific capacity (~200 mAh/gcathode) but suffers from high irreversible capacity loss during the first cycles and capacity fading during cycling. The Li4Ti5O12//LiCo2/3Ni1/6Mn1/6O2 cell demonstrated excellent cycling properties at different C-rates with 100% capacity retention after 150 cycles at 1 C. Although the working voltage (~2.2 V) and the specific capacity (~140 mAh/gcathode) are lower than those of the MnSn2//LiCo2/3Ni1/6Mn1/6O2 configuration, the other measured electrochemical properties suggest that the Li4Ti5O12//LiCo2/3Ni1/6Mn1/6O2 full cell is a potential candidate for battery application due to its excellent cycling performance and improved safety.

AMPA receptors (AMPARs), one of three sub-groups of ionotropic glutamate receptors present in the central nervous system, are recognised for their involvement in long-term potentiation (LTP), and learning and memory processes. [1] They represent a valid cognitive enhancer target, particularly in the fight against Alzheimer’s disease (AD). [2,3] Benzothiadiazine 1,1-dioxides, such as BPAM121, have emerged as important allosteric modulators of AMPARs, working solely in the presence of the endogenous transmitter. [4] Synthesis of BPAM121 labelled with fluorine-18 was proposed, to investigate the utility of this molecule as a PET probe in vivo, and evaluate its potential as an AD diagnostic tool (Figure 1). [Figure 1. a) Structure of BPAM121, b) Established radiochemical synthesis of [18F]BPAM121.] This work documents the successful optimization of synthesis, purification and formulation of [18F]BPAM121 using an automated FASTlab (GE Healthcare) synthesizer. In particular, the influence of higher-level [18F]fluoride ion starting concentrations on final product formulation requirements is discussed. Initial results revealed [18F]BPAM121 successfully passes the blood brain barrier, and further biological studies are currently underway. References [1] S. F. Traynelis et al. Pharmacol.
