TL;DR: A simple and effective ultrasound-assisted wet impregnation method was developed for the preparation of magnetically separable TiO2/maghemite-silica photo-active nanocomposites as discussed by the authors.
Abstract: A simple and effective ultrasound-assisted wet impregnation method was developed for the preparation of magnetically separable TiO2/maghemite-silica photo-active nanocomposites. The resulting nanomaterials were characterized by several techniques and subsequently tested for their photocatalytic activities in the liquid phase selective oxidation of benzyl alcohol. An unprecedented selectivity in organic media (90% in acetonitrile) towards benzaldehyde was achieved at a benzyl alcohol conversion of ca. 50%, being remarkably superior in terms of activity to any other supported transition metal catalysts reported to date as well as commercial titania Evonik P-25 photocatalyst.

TL;DR: In this paper, the mixed transition-metal spinel oxide NiFe2O4 was used as active electrode materials vs lithium metal in test cells and reversible capacities close to 900 mAh/g were found due to the poorly crystalline nature of the products of electrochemical reaction.

TL;DR: Surprisingly, there is a negative correlation between the number of articles published by the respondents and their opinion on the impact factor, and the results show that the opinion is slightly above the median which could be understood as “neither positive nor negative”.
Abstract: The impact factor is a highly polemic metric. It was designed to help scientists in searching for bibliographic references for their own works, enabling communication among researchers and helping librarians in deciding which journal they should purchase. Nevertheless, it has soon become the most important measure of scientific performance applied to journals, articles, scientists, universities, etc. Since then, some researchers argue that it is a useless and flawed measure, while others defend its utility. The current study is the first survey on the opinion on the topic of a broad sample of scientists from all over the world. The questionnaire was answered by 1,704 researchers from 86 different countries, all the continents and all the UNESCO major fields of knowledge. The results show that the opinion is slightly above the median which could be understood as "neither positive nor negative". Surprisingly, there is a negative correlation between the number of articles published by the respondents and their opinion on the impact factor.

TL;DR: Although the pooled estimates show that coffee consumption is inversely associated with the risk of AD, the four studies had heterogeneous methodologies and results, suggesting further prospective studies evaluating the association between coffee consumption and AD are strongly needed.
Abstract: Purpose: To estimate the pooled risk of coffee consumption for Alzheimer's disease (AD). Material and methods: We have reviewed all observational studies that evaluated the association between AD risk and coffee consumption. Four studies were identified: two case-control studies and two cohorts. These studies were carried out between 1990 and 2002. Results: There was an obvious protective effect of coffee consumption in the pooled estimate [risk estimate: 0.73 (95% confidence interval: 0.58–0.92)]. However, the homogeneity test was highly significant (p<0.01), indicating heterogeneity across the pooled studies. Pooled analysis applying the random effect model was 0.79 with 95% confidence interval overlapping unity (95% confidence interval: 0.46–1.36). Three studies assessed coffee consumption by interview questionnaire. The risk of AD in coffee consumers versus non-consumers in studies that used interview questionnaire had a pooled risk estimate of 0.70 with 95% confidence interval 0.55–0.90. Con...
