TL;DR: In this paper, the authors studied the grain-mass evolution of a dust cloud embedded in a rarefied turbulent gas environment in which the initially monodisperse spherical SiO 2 grains (1.9 μm diameter) rapidly aggregate.

TL;DR: Owing to the versatility of nanoparticles, researchers envision the combination of multiple modalities to one carrier, which has been challenging due to the necessity of the adaptation of at least partially counteracting parameters between the different modalities.

TL;DR: Magnetic heating of breast tumors is a promising technique for future interventional radiologic treatments as well as a selective application of magnetite and exposure of the breast to an alternating magnetic field.
Abstract: PURPOSE: To assess relevant parameters for the minimally invasive elimination of breast tumors by using a selective application of magnetite and exposure of the breast to an alternating magnetic field. MATERIALS AND METHODS: The specific absorption rate (SAR) of different magnetite samples was determined calorimetrically. Temperature elevations based on magnetite mass (7–112 mg) and magnetic field amplitude (1.2–6.5 kA/m; frequency, 400 kHz) were investigated by using human breast tissue. Parameter combinations (21 mg ± 9 [SD], 242-second magnetic field exposure, 6.5-kA/m amplitude) were tested in 10 immunodeficient mice bearing human adenocarcinomas (MX-1 cells). Histologic sections of heated tumor tissue were analyzed. RESULTS: SAR data of different magnetite particle types ranged from 3 to 211 W/g. Temperature elevation (ΔT) as a function of the magnetite mass increased linearly up to 28 mg; at higher masses, a saturation of ΔT was observed at nearly 88°C. The dependence of ΔT on magnetic field amplitu...

TL;DR: In this article, a survey of 800 business associations was conducted to understand why interest groups lobby the EU institutions and what groups maintain contacts with them, and four main dimensions influence access patterns: institutional context, resource dependencies, interest group organization and strategic choices.
Abstract: Drawing on a survey of 800 business associations, the article seeks to explain why interest groups lobby the EU institutions and what groups maintain contacts with them. Rooted in organizational theory, it argues that four main dimensions influence access patterns — institutional context, resource dependencies, interest group organization, and strategic choices. The empirical analysis demonstrates that all dimensions are relevant. Nonetheless, contacts between EU policy-makers and interest groups display only a few general traits: they are shaped by the political mobilization of groups in response to EU regulation, the division of labour among EU and national associations and the importance of organizational resources. Beyond these general influences, the interactions vary profoundly in the segmented institutional context.

TL;DR: In this article, a high-throughput approach based on density functional theory was used to perform an extensive study of possible ABX3 perovskites, where X is a non-metal and A and B span a large portion of the periodic table.
Abstract: Using a high-throughput approach based on density functional theory, we perform an extensive study of possible ABX3 perovskites, where X is a non-metal and A and B span a large portion of the periodic table. We calculate the ternary phase diagram for each composition and we discuss the thermodynamic stability of perovskite phases. We find a large number of ABX3 perovskites, which are still absent from available databases, and which are stable with respect to decomposition into known ternary, binary or elementary phases. For these structures, we then calculate electronic band gaps, hole effective masses, and the spontaneous ferroelectric and magnetic polarization, which are relevant material properties for a number of specific applications in photovoltaics, transparent contacts, piezoelectrics, and magnetoelectrics. Some of our novel perovskites exhibit promising properties for applications.
