Gem‐Diboronic Acids: A Motif for Anion Recognition in Competitive Media
Angewandte Chemie, EarlyView.Gem‐diboronic acids are an anion recognition motif that provides strong and directional binding to oxoanions in aqueous media. This motif provides a selectivity profile that is distinct from other anion recognition groups, and binding affinities that are superior to those of simple amides and (thio)ureas.

Angewandte Chemie, EarlyView.Ultrathin rhodium–antimony alloy nanoflowers with unconventional 2H phase were controllably synthesized via a facile one‐pot method. Benefitting from the enhanced electronic interaction by p–d orbital coupling, the prepared catalyst delivered an efficient ammonia electrosynthesis capacity in neutral media.

Nitrite metabolism in the cyanobacterium Anabaena cycadeae: Regulation of nitrite uptake and nitrite reductase by ammonia [PDF]
FEMS Microbiology Letters, 1992 Nitrogen regulation of nitrite uptake and nitrite reductase was studied in the cyanobacterium Anabaena cycadeae and its glutamine-auxotrophic mutant. The development of the nitrite-uptake system preceded, and was independent of, the development of nitrate reductase.

Boosting Nitrate Electroreduction to Ammonia on Alloying of Cu With Au by Accelerated Proton Relay
Aggregate, EarlyView.Carbon‐supported coral‐like Au3Cu alloy relay catalysts were synthesized by electrodeposition and used for the reduction of NO3− to NH3, where the NH3 production rate was 1719.3 µg h−1 cm−2 at −0.5 V. Theoretical density functional theory results show that Cu in the catalyst favors the reduction of NO3– to *NO, while Au favors the reduction of *NO to ...

Effect of temperature and type of packages on nitrates and nitrites content in lettuce
Acta Agrobotanica, 2013 Lettuce wrapped in unperforated PE film, perforated PE film, stretch film and without wrapping was stored at 1, 6, 20 and 28°C. Freshly harvested lettuce and after one day of storage, independently on storage conditions, did not contains nitrites ...

Soil biome variation of Lupinus nipomensis in wet‐cool vs. dry‐warm microhabitats and greenhouse
American Journal of Botany, EarlyView.Abstract Premise Environmental DNA (eDNA) can be used to determine the composition of the soil biome community, revealing beneficial and antagonistic microbes and invertebrates associated with plants. eDNA analyses can complement traditional soil community studies, offering more comprehensive information for conservation practitioners. Studies are also

ChemPhotoChem, Volume 6, Issue 12, December 2022., 2022 Photoswitchable cross‐linkers have the ability to connect two residues on a biomolecule, thereby causing large changes in the structure and function of the target upon irradiation. The design, synthesis and purification of cross‐linkers with large end‐to‐end distances remains challenging, especially for applications in chemical biology.

A Novel Merocyanine Derivative for Probing Polarity at Cubosome Interfaces
Asian Journal of Organic Chemistry, Accepted Article.This study reports the development of a synthetic route for the chemical environment sensor C10SP, designed for incorporation into phytantriol‐based cubosomes. The molecule combines an apolar aliphatic tail for lipid bilayer anchoring with a polarity‐sensitive chromophore.

Electronic structure of nanocones of boron nitrite [PDF]
Applied Physics Letters, vol 82 (14), p. 2323-2325, 7 April 2003, 2004 We apply first-principles calculations to study the electronic structure of boron nitride nanocones with disclinations of different angles $\theta=n\pi/3$. Nanocones with odd values of $n$ present antiphase boundaries that cause a reduction of the work function of the nanocones, relative to the bulk BN value, by as much as 2 eV.
