Material mixtures offer new possibilities for synthesizing coating materials with tailored optical and mechanical properties. We present experimental results on mixtures of HfO2, ZrO2, and Al2O3, pursuing applications in UV coating technology, while the mixtures are prepared by magnetron sputtering, ion beam sputtering, plasma ion-assisted deposition (PIAD), and electron beam evaporation without assistance. The properties investigated include the refractive index, optical gap, thermal shift, and mechanical stress. The first high reflectors for UV applications have been deposited by PIAD.

Background: Normothermic ex situ heart perfusion (ESHP) has emerged as a valid modality for advanced cardiac allograft preservation and conditioning prior to transplantation though myocardial function declines gradually during ESHP thus limiting its potential for expanding the donor pool. Recently, the utilization of dialysis has been shown to preserve myocardial and coronary vasomotor function. Herein, we sought to determine the changes in myocardial metabolism that could support this improvement.

The oceanic dissolved organic matter (DOM) reservoir is one of Earth's largest carbon pools, yet the factors contributing to its recalcitrance and persistence remain poorly understood. Here, we employed ultra-high resolution mass spectrometry (UHRMS) to examine the molecular dynamics of DOM from terrestrial, marine and mixed sources during bio-incubation over weekly, monthly, and one year time spans. Using Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS), we classified DOM into three distinct categories (Consumed, Resistant and Product) based on their presence or absence at the start and end of the incubation.

To solve the energy crisis and environmental issues, it is essential to create effective and sustainable energy conversion and storage technologies. Traditional materials for energy conversion and storage however have several drawbacks, such as poor energy density and inadequate efficiency. The advantages of MOF-based materials, such as pristine MOFs, also known as porous coordination polymers, MOF composites, and their derivatives, over traditional materials, have been thoroughly investigated.

Background: (Cardamom) and (Fennel) are well-known spices and are also used as natural mouth fresheners. This study was performed to evaluate their neuroprotective ability based on certain acellular and cellular assays.
Methods: Hexane and ethyl acetate extracts were prepared using cardamom and fennel seeds.
