Prof. Alois Fürstner and co-workers at Max Planck Institut für Kohlenforschung developed a new class of molybdenum alkylidyne catalysts equipped with tripodal silanolate ligands which mark a significant milestone in the field of alkyne metathesis. Their improved stability, functional group tolerance, and ease of synthesis position them as valuable tools for researchers and industry professionals alike, promising to expand the scope of alkyne metathesis applications ...

Since 2000 bioinspired fibrillar dry adhesives have been studied intensively culminating in commercial products already available on the market. Currently known fibrillar adhesives are fully wetted by oils, leading to significantly decreased adhesion and friction performance. Therefore, a high demand exists for reversible dry fibrillar adhesives that can repel oil-like liquids and adhere strongly to surfaces wetted by them.

To meet the aforementioned challenges, an extraordinary fibrillar ...

Prof. Kai Sundmacher and co-workers at the MPI for Dynamics of Complex Technical Systems developed a novel core-shell catalyst design with a highly active catalyst core surrounded by an inert, low-permeability shell. The new catalyst design leads to an intrinsic heat management that avoids hotspots in strongly exothermic reactions. This allows faster reactor start-up and shut-down and makes the catalysts suitable for rapid load changes in discontinuous processes.

We offer an innovative aqueous composition that promotes ice nucleation at high efficiencies, even at extremely low concentrations of ice-nucleating particles. This breakthrough is particularly relevant in the fields of agriculture, atmospheric science, and the biosphere, where the control over ice formation can significantly impact environmental dynamics and technological applications.

LEL technology stands out for its precision in fabricating 3D metal microarchitectures with intricate geometries and the ability to seamlessly integrate liquids. It utilizes a voxel-by-voxel deposition method, which allows for the creation of complex shapes with submicron resolution. The process involves optimizing variables like deposition voltage, air pressure, and orifice diameter. A significant advantage of LEL is its capacity to alter the pH and composition of the supporting electrolyte solution, ...

We offer a new simple and low cost technology to fabricate graphene-encapsulated metal or metal compound nanoparticles. The resulting hybrid nanoparticles are protected by granted substance claims in US, CN, TW and EP (DE, FR, GB, BE). Currently the patent protected graphene coated nano particles are discussed as high performance electrode materials in the lithium ion battery business (for example Samsung's "Graphene Balls").

We offer a new family of cationic ligands, namely N-alkyl/aryl pyridiniophosphines. The ligands can be synthesized through a short, scalable, and highly modular route.

Evaluation of their electronic properties evidenced weak σ-donor and quite strong π-acceptor character when used as ancillary ligands.

For the evaluation of crystallisation processes, process parameters like temperature and concentration can be easily measured. However, to measure the crystal size distribution continuously is a challenging task.
Different methods relaying on back scattering or reflection of monochromatic light can be applied that yield chord-length distributions, which often deviate from the actual crystal or particle size distribution. For analysing the true crystal dimensions and, additionally, the crystal ...

Mesoporous materials present a large surface-to-volume ratio providing sites for catalysis, molecular separation, adsorption or chemical sensing. Some of the classical mesoporous materials employed include silica, alumina, zirconia, zeolites, and other diverse oxides such Ti or Co, and they are synthetized by routes as self-assembly, sol-gel, spray drying and some variations of these methods known in the state of the art. Additionally, some elements of the platinum group such as Pd, Ru, and their ...

Driven by the favourable operational effectiveness of neodymium iron boron (NdFeB) magnets, there has been a considerably rising demand for neodymium in permanent magnet manufacturing. According to Spherical Insights & Consulting the global neodymium magnet market size was valued at 2.3 Billion US$ in 2022 and is expected to reach 3.83 Billion US$ by 2032. As the market for rare earth materials is heavily influenced by Chinese supplies, which causes supply and price uncertainties, end users ...

The ability of hypervalent iodine compounds to act as electrophilic group-transfer reagents has been extensively exploited during the last several years in a variety of synthetically useful transformations
like cyanations and alkynylations. Now it was found, that novel imidazolium sulfuranes, which are isolobal to I(III) species and also depict the key threecenter four-electron bond motive, can be used as an alternative platform for the development of new electrophilic group-transfer reagents.

Imidazolium ...
