Organic–inorganic (O–I) hybrid nanocomposites have already been widely investigated in the optoelectronic industry and are emerging in the biomedical field. In both cases, a thorough knowledge of the O–I hybrid morphology is key for reaching tailored properties of the devices; however, up to now little is known on this matter. Herein, we used advanced X-ray scattering and microscopy techniques to
Jerk, the derivative of acceleration with respect to time, is a physical concept of great practical significance. However, this concept is rarely mentioned in textbooks and is often neglected in physics education. This paper describes how the concept of jerk can be easily introduced in the study of the dynamics of falling bodies, which are significantly affected by air resistance. In this regard,
Previous research suggests that parties in contractual relationships adopt a governance structure that economizes on transaction costs, and then over time learn to govern the contractual relationships in a more efficient manner by incrementally aligning contractual terms with transaction attributes based on new experiences made in the relationship. This implies that learning to contract and the de
In recent decades, laser systems emitting pulses of light containing only a few electric field oscillations under their envelope have become common in many ultrafast optics laboratories. Owing to unique temporal characteristics and achieving extreme field strengths, these so-called few-cycle pulses have been instrumental in unlocking new regimes of light-matter interaction.The work presented in
Our aim was to understand mechanisms for clustering and cross-linking of gliadins, a wheat seed storage protein type, monomeric in native state, but incorporated in network while processed. The mechanisms were studied utilizing spectroscopy and high-performance liquid chromatography on a gliadin-rich fraction, in vitro produced α-gliadins, and synthetic gliadin peptides, and by coarse-grained mode
The present study investigates the potential benefits of the Mexican medicinal plant Lopezia racemosa (Onagraceae). Extracts and fractions from aerial parts of this plant were assessed to determine their antibacterial, antifungal, antiparasitic, anti-inflammatory and cytotoxic activities in vitro. Aerial parts of the plant were extracted with various solvents and fractionated accordingly. Extracts
Ethnopharmacological relevance: To study the potential benefit of the traditional Mexican medicinal plant Galium mexicanum Kunth (Rubiaceae). Hexane, chloroform, and methanol extracts as well as various fractions from these extracts were tested to determine antibacterial, antifungal, antiparasitic or anti-inflammatory activities in vitro. Materials and methods: Aerial parts of the plant were extra
Flerovium (Fl, element 114) is the heaviest element chemically studied so far. To date, its interaction with gold was investigated in two gas-solid chromatography experiments, which reported two different types of interaction, however, each based on the level of a few registered atoms only. Whereas noble-gas-like properties were suggested from the first experiment, the second one pointed at a vola
Here we report large-amplitude transit timing variations (TTVs) for AU Microcopii b and c as detected in combined TESS (2018, 2020) and CHEOPS (2020, 2021) transit observations. AU Mic is a young planetary system with a debris disk and two transiting warm Neptunes. A TTV on the order of several minutes was previously reported for AU Mic b, which was suggested to be an outcome of mutual perturbatio
We study the structure of the backward shift invariant and nearly invariant subspaces in weighted Fock-type spaces ℱWp, whose weight is not necessarily radial. We show that in the spaces ℱWp, which contain the polynomials as a dense subspace (in particular, in the radial case), all nontrivial backward shift invariant subspaces are of the form ℘n, that is, finite-dimensional subspaces consisting of
Background: Multimorbidity is a rising global phenomenon, placing strains on countries’ population health and finances. This systematic review provides insight into the costs of multimorbidity through addressing the following primary and secondary research questions: What evidence exists on the costs of multimorbidity? How do costs of specific disease combinations vary across countries? How do mul
An increasing number of countries are accepting individuals with diverse religious and ethnic backgrounds within their borders – a trend that can be traced to the end of WWII. Theoretically, a society can experience both economic benefits and costs from ethno-confessional diversity. As economies become more open and interconnected, it is vital to have an adequate answer to the question of how ethn
Financial Repression is increasingly recognized as a viable approach to address high and unsustainable debt levels. Despite its history dating back to the early-mid 1900s, the economic implications of Financial Repression have yet to be fully explored. This paper investigates the effects of Financial Repression, specifically the relationship between two key economic indicators: the exchange rate a
Värmeväxlare är system som ofta används i många olika tillämpningsområden så som kylning, uppvärmning, ventilation eller andra områden där man strävar efter att maximera värmeutbytet mellan fluider. Vanliga tillverkningsmetoder för värmeväxlare inkluderar hydraulisk pressning av värmeöverförande plattor, eller att på andra sätt skapa värmeöverförande ytor av rör, korrugerad plåt eller liknade mateHeat exchangers are systems commonly used in many different applications such as cooling, heating, ventilation, and other areas where maximizing the heat transfer between fluids is desirable. Common manufacturing techniques of heat exchangers include hydraulic pressing of heat-transferring plates, or otherwise creating a heat-transferring area of pipes, corrugated sheet metal, or similar materials
Fat-filled milk powders are manufactured by blending skim milk powder with vegetable oil and these powders have gained a great economic importance. Sensible selection of vegetable oil can help in satisfying both nutritional features and functional characteristics of fat for dairy application. The stability of milk powders can be affected by its composition, mainly the composition of fats which can
Acoustophoresis has proven to be a promising technique when it comes to separation of particles or cells in a microchip. One of the main areas of interest is the separation of so called circulating tumor cells (CTCs) from whole blood - which could serve as an indication of early stage cancer or in general be studied in order to obtain more information about these cells. However, one issue with th
