Niobium pentoxide nanomaterials with distorted structures as efficient acid catalysts
Niobium pentoxides are promising acid catalysts for the conversion of biomass into fuels and chemicals. Developing new synthesis routes is essential for designing niobium pentoxide catalysts with improved activity for ...
Molecular Bottle Brushes with Positioned Selenols
Extending the Toolbox of Oxidative Single Polymer Chain Folding with Conformation Analysis by Atomic Force Microscopy
A synthesis route to controlled and dynamic single polymer chain folding is reported. Sequence‐controlled macromolecules containing precisely located selenol moieties within a polymer chain are synthesized. Oxidation of ...
Mussel-Inspired Polymerization of Peptides
The Chemical Activation Route as Key to Broaden the Sequential Space of Artificial Mussel-Glue Proteins
A previously introduced tyrosinase‐activated polymerization of Tyr‐ and Cys‐bearing peptides yielding artificial mussel‐glue proteins is realized without the need of the specific enzyme by a chemical activation route. This ...
Cobalt-Assisted Morphology and Assembly Control of Co-Doped ZnO Nanoparticles
The morphology of metal oxide nanostructures influences the response of the materials in a given application. In addition to changing the composition, doping can also modify the morphology of a host nanomaterial. Herein, ...
Towards Initial Indications for a Thiol-Based Redox Control of Arabidopsis 5-Aminolevulinic Acid Dehydratase
Thiol-based redox control is one of the important posttranslational mechanisms of the tetrapyrrole biosynthesis pathway. Many enzymes of the pathway have been shown to interact with thioredoxin (TRX) and Nicotinamide adenine ...
Selected Plant Metabolites Involved in Oxidation-Reduction Processes during Bud Dormancy and Ontogenetic Development in Sweet Cherry Buds (Prunus avium L.)
Many biochemical processes are involved in regulating the consecutive transition of different phases of dormancy in sweet cherry buds. An evaluation based on a metabolic approach has, as yet, only been partly addressed. ...
Polyphenols from Tamarix nilotica: LC−ESI-MSn Profiling and In Vivo Antifibrotic Activity
Tamarix nilotica (Ehrenb.) Bunge (Tamaricaceae), an indigenous plant to the Middle East region, is well-known as a medicinal plant for treating many human ailments. The current study aimed at exploring the polyphenol profile ...
Fluorolytic Sol−Gel Synthesis of Nanometal Fluorides: Accessing New Materials for Optical Applications
The potential of fluorolytic sol–gel synthesis for a wide variety of applications in the field of optical materials is reviewed. Based on the fluorolytic sol–gel synthesis of nanometal fluorides, sols of complex fluorometalates ...
SERS probing of proteins in gold nanoparticle agglomerates
The collection of surface-enhanced Raman scattering (SERS) spectra of proteins and other biomolecules in complex biological samples such as animal cells has been achieved with gold nanoparticles that are introduced to the ...
Evaluating the Solvent Stark Effect from Temperature-Dependent Solvatochromic Shifts of Anthracene
The solvent Stark effect on the spectral shifts of anthracene is studied with temperature‐dependent solvatochromic measurements. The Stark contribution ΔvStark to the absorption shift Δvp in polar solvents is measured to ...
