The activation and selective transformation of virtually inexhaustible or easy-to-generate chemicals like N2, O2, CO2, CO, H2, methane gas to value-added products is a lively area current research, because its economic relevance as well huge ecological impact. Biologists chemists have put forth lot effort toward understanding modeling the mechanisms biological small-molecule activation, in several catalytic cycles proposed for nickel-containing enzymes, nickel(I) plays key role. In recent...
Diclofenac (DCF) is one of the most widespread and consumed analgesics, thereby causing contamination water bodies on a global scale. A common approach to tackle this pressing issue adsorption DCF exploiting highly hydrophobic polymers. However, controlling morphology such polymers essential. Adsorption capacities presented conjugated microporous polymer (CMP) in bulk‐form, for ( q sat ) are as low 13.0 mg g −1 despite exhibiting additional nitrogen moieties specifically target DCF. Herein,...
Abstract Reduced CO 2 species are key intermediates in a variety of natural and synthetic processes. In the majority systems, however, they elude isolation or characterisation owing to high reactivity limited accessibility (heterogeneous systems), their formulations thus often remain uncertain based on calculations only. We herein report Ni−CO 2− complex that is unique many ways. While its structural electronic features help understand ‐bound state Ni,Fe carbon monoxide dehydrogenases, sheds...
More than 20 years ago, acrylamide was added to the list of potential carcinogens found in many common dietary products and tobacco smoke. Consequently, human biomonitoring studies investigating exposure form adducts blood metabolites urine have been performed obtain data on actual burden different populations world Europe. Recognizing related health risk, European Commission responded with measures curb content food products. In 2017, a trans-European project (HBM4EU) started aim...

Abstract The formation of well‐defined, functional surfaces that incorporate the unique properties inorganic nanoparticles (NPs) requires robust and scalable fabrication strategies. Herein, we report a methodology for decoration polymer molds with plasmonic (gold) nanoparticle arrays. Wrinkled soft templates were used to assemble gold NPs (74 nm) into line These pre‐formed arrays transferred in subsequent step onto polycarbonate via an injection molding process. Scanning electron microscopy...
Abstract Reduzierte CO 2 ‐Spezies sind wichtige Intermediate in einer Vielzahl von natürlichen und synthetischen Prozessen. In den meisten Systemen entziehen sie sich jedoch aufgrund ihrer Reaktivität oder eingeschränkten Zugänglichkeit (heterogene Systeme) der Isolierung Charakterisierung bleiben daher oft spekulativ nur theoretisch begründet. Hier wird ein Ni‐CO 2− ‐Komplex vorgestellt, vielerlei Hinsicht einzigartig ist. Während seine strukturellen elektronischen Eigenschaften helfen,...
Due to the existence-threatening risk aquatic life and entire ecosystems, removal of oxyanions such as sulfate phosphate from anthropogenic wastewaters, municipal effluents acid mine drainage, is inevitable. Furthermore, phosphorus an indispensable resource for worldwide plant fertilization, which cannot be replaced by any other substance. This raises one most important mineral resources worldwide. Thus, efficient recovery essential ecosystems economy. To face harsh acidic conditions,...
The separation of toxic pollutants such as Pb2+, Cd2+, and Al3+ from water is a constant challenge contamination natural bodies increasing. especially Pb2+ Cd2+ are ecotoxic highly for humans, even in ppb concentrations, therefore removal below dangerous level demanding. Herein, the potential adsorber material starch, being ecofriendly, cheap, abundantly available, was investigated. Thus, four different native starch samples (potato, corn, waxy wheat starch) two oxidized starches (oxidized...
Even though β-diketiminato nickel(<sc>ii</sc>) bromide and cobaltocene have nearly identical redox potentials the corresponding electron transfer complex can be crystallised from equilibrium activates CO<sub>2</sub> to form a mononuclear carbonate.
Conjugated Microporous Polymers In article 2200385, Martin Mayer, Dana Schwarz, and co-workers show that adsorption of anthropogenic contaminants such as pharmaceuticals requires tailored adsorbents conjugated microporous polymers. Coating these polymer networks around mesoporous silica increased the performance enabled easy separation by sedimentation. Easy purification allowed reuse hybrid materials.
Polymer surface modification is a key step in manufacturing for applications of parts biotechnology, catalysis, sensing, and other fields. However, functionalization approaches with sufficient robustness are often connected the use harsh chemical treatment and/or high-energy consumption. We present versatile approach polymer surfaces, which compatible fused filament fabrication, energy efficient, does not require harmful chemicals. The takes advantage embedding polyethylenimine-coated...
We present a new approach of surface functionalization polyether ether ketone (PEEK) that is carried out during the molding step. Thin films polymers with different functional groups were applied to mold and brought in close contact PEEK melt injection molding. The surfaces produced parts characterized after solidification. Only those bearing primary amino exhibited wettability for water. Obviously, thin polymer film was grafted by chemical reaction initiated high temperature. formation...
