- Molecular imprinting is an attractive method for producing highly selective adsorbents, and several new and potentially useful applications based on molecularly imprinted polymers (MIPs) have been described in recent years. In this article, we highlight some of the areas where these materials have found application, and also describe some new fields of application where the selectivities of imprinted materials can be gainfully employed, for example as binding matrices in the screening of combinatorial libraries, and as auxiliary agents in enzymatic syntheses.

- Molecularly imprinted polymers were prepared using 2-vinylpyridine and/or methacrylic acid as functional monomers in a self-assembly imprinting protocol. The resulting polymers were analyzed in aqueous media, and the effects from the pH of the mobile phase and the degree of added organic solvent were investigated. The results are indicative of the importance of ionic bonds in conjunction with hydrophobic interactions in the formation of the complexes between the analyte and the polymers.

- Pancreatic cancer is the fourth most common cause of cancer death worldwide with large geographical variation, which implies the contribution of diet and lifestyle in its etiology. We examined the association of meat and fish consumption with risk of pancreatic cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC). A total of 477,202 EPIC participants from 10 European countries recruited between 1992 and 2000 were included in our analysis. Until 2008, 865 nonendocrine pancreatic cancer cases have been observed. Calibrated relative risks (RRs) and 95% confidence intervals (CIs) were computed using multivariable-adjusted Cox hazard regression models. The consumption of red meat (RR per 50 g increase per day = 1.03, 95% CI = 0.931.14) and processed meat (RR per 50 g increase per day = 0.93, 95% CI = 0.711.23) were not associated with an increased pancreatic cancer risk. Poultry consumption tended to be associated with an increased pancreatic cancer risk (RR per 50 g increase per day = 1.72, 95% CI = 1.042.84); however, there was no association with fish consumption (RR per 50 g increase per day = 1.22, 95% CI = 0.921.62). Our results do not support the conclusion of the World Cancer Research Fund that red or processed meat consumption may possibly increase the risk of pancreatic cancer. The positive association of poultry consumption with pancreatic cancer might be a chance finding as it contradicts most previous findings.

Konferensbidrag (refereegranskat)abstract
- As microelectronic devices continue to decrease in size, failure of these devices is commonly attributed to ineffectual thermal management. Hence, increased thermal failures at elevated temperature has accounted for some of their reliability concerns and expected to be a major bottleneck for future development of microelectronics. For the thermal management, solder based materials give a better performance as thermal interface materials (TIM). However, these materials have a marginal reliability due to their higher Young's modulus. Therefore new type of solder based nano polymer composite (SMNPC) material is introduced. The SMNPC is composed of Sn-Ag-Cu (SAC) infiltrated through a silver coated PA6, 6 polymer fiber mesh to address electrical, thermal and mechanical challenges. In this work, finite element modeling was employed to investigate the thermal and mechanical properties of the composite material by varying polymer distribution, total volume of polymer and bond fine thickness (BLT). The composite is demonstrated to possess high heat transfer capability and lower elastic modulus as shown in Figure 1. All the results demonstrate that the developed SMNPC is proved a good alternative for conventional TIMs to improve thermal and mechanical properties.

- We compute reconstructions of 4D and 5D fast-ion phase-space distribution functions in fusion plasmas from synthetic projections of these functions. The fast-ion phase-space distribution functions originating from neutral beam injection (NBI) at TCV and Wendelstein 7-X (W7-X) at full, half, and one-third injection energies can be distinguished and particle densities of each component inferred based on 20 synthetic spectra of projected velocities at TCV and 680 at W7-X. Further, we demonstrate that an expansion into a basis of slowing-down distribution functions is equivalent to regularization using slowing-down physics as prior information. Using this technique in a Tikhonov formulation, we infer the particle density fractions for each NBI energy for each NBI beam from synthetic measurements, resulting in six unknowns at TCV and 24 unknowns at W7-X. Additionally, we show that installing 40 LOS in each of 17 ports at W7-X, providing full beam coverage and almost full angle coverage, produces the highest quality reconstructions.
