The air we breathe is full of microscopic particles. This particulate matter is very complex, both in size and composition. Different components of particulate matter contain metal oxides, silica dust, and soot particles. Soot particles are a major form of air pollution in the industrialized world. Every combustion engine that runs, barbecues and campfires that are lit, and unwanted (natural) fires release huge amounts of soot particles into the atmosphere.

Researchers find soot particles in vital organs of the unborn.

The richness and complexity of physical and chemical processes in perovskites make correlative investigations necessary for a comprehensive understanding on perovskites and their optoelectronic devices.

Catalysis forms the cornerstone of the chemical industry, with over 90% of the industrial-scale processes involving at least one catalytic step, mainly carried out using heterogeneous catalysts.

Since its emergence, microfluidics has proven to be a powerful tool in chemistry and the life sciences. Microfluidic devices, consisting of networks of micron-scale flow channels, leverage high surface-area-to-volume ratios and precision fluid control to provide advantages over conventional methods in chemistry and biology. In chemistry, reactions with greater speed, selectivity, and safety can be achieved thanks to fast mixing and efficient heat transfer. In biology, greater control over mechanical and biochemical microenvironments allow cell culture studies with greater relevance to living organisms.

The generation of clean, renewable energy sources has been a hot research topic for the past decades. Photocatalysis is a plausible way to store intermittently available solar energy in chemical

A team of scientists has shown that Bromine (Br) incorporation in polycrystalline cesium lead triiodide (CsPbI3) thin films, with composition CsPbI3-xBrx, modifies the crystal structure by changing the symmetry of the lattice. This change, in turn, governs the formation of the different, energetically favored textures within the thin film. Controlling grain orientations within polycrystalline all‐inorganic halide perovskite solar cells can help increase conversion efficiencies, which would represent great progress in the field of renewable energies. This discovery comes directly from synchrotron X‐ray diffraction experiments carried out at the ALBA Synchrotron and the European Radiation Facility in Grenoble.

Since Fujishima and Honda first reported in 1972 the photoelectrochemical water splitting of water through TiO2 under UV light irradiation, photocatalysis has attracted a growing amount of research attention. Various types of materials with photocatalytic properties such as metal oxides, metal sulfides, polymers, MOFs etc have been reported for solar energy conversion, storage and utilization, through redution and/or oxidation reactions generating added value products including hydrogen, oxygen and hydrocarbons. Recently, metal halide perovskites(MHPs) have found tremendous popularity in solar to electricity conversion due to the high extinction coefficients, the wide absorption range and long electron−hole diffusion lengths of these materials. All of the mentioned MHP properties match well with the necessary conditions set forward for photocatalytic materials making them potentially interesting photocatalyst, a main concern is however related to their (chemical) stability under reaction conditions.
