Sweet silver: A formaldehyde-free silver staining using aldoses as developing agents, with enhanced compatibility with mass spectrometry [PDF]
Protein detection methods after electrophoresis have to be sensitive, homogeneous, and not to impair downstream analysis of proteins by MS. Speed, low cost, and user friendliness are also favored features. Silver staining combines many of these features,

The larger ion size of Na+ versus with Li+ has a pronounced impact on the intercalation chemistry of disordered rocksalt cathode materials. On charge, the disordered rocksalt structure is retained in Li2MnO2F but it is lost in Na2MnO2F resulting in extensive amorphization.

Calcification of the medial layer of arteries, often termed Monckeberg’s arteriosclerosis , is common in CKD and present in most patients with ESRD ([1][1]). Although it likely has detrimental long-term consequences, it is generally a chronic, asymptomatic condition. However, in a few patients,

Electrochemistry and Spectroscopy of Sulfate and Thiosulfate Complexes of Iron Porphyrins [PDF]
The electrochemical and spectroscopic properties of the complex formed by the addition of thiosulfate to ferric porphyrins were examined. The NMR spectrum of the thiosulfate–ferric porphyrin complex was consistent with a high-spin ferric complex, while ...

Investigation of the Degradation of Chelate Complexes in Liquid Redox Desulfurization Processes [PDF]
Metal complexes such as Fe‐EDTA, which are used as pseudo‐catalysts or oxygen carriers in wet oxidative desulfurization processes, are subject to a degradation mechanism that significantly influences the economics of such processes. Therefore, this study

Sonicated Carbon Nanotube Catalysts for Efficient Point‐of‐use Water Treatment
The growing demand for freshwater and rising contamination of water sources require innovative treatment technologies. Sonicated carbon nanotubes can activate persulfate for selective contaminant degradation via nonradical pathways. This scalable approach enables rapid pollutant removal, offering a sustainable solution for decentralized freshwater ...

Non-Cyanide Silver as a Substitute for Cyanide Processes [PDF]
Since the mid 1800s, silver has been deposited from a cyanide-based formulation on a commercial basis. Commercial non-cyanide silver plating solutions were first made generally available in the late 1970s, and yet today the vast majority, and nearly ...
