A micromethod for the determination of arginine [PDF]

, 1941
Micromethods for the determination of arginine based on the use of the Sakaguchi reagent have been described (14). This reagent gives a strong color with glycocyamine, arginine, and other monosubstituted guanidine derivatives.

Challenges and Opportunities in the Use of Iron Photosensitizers for Dye‐Sensitized Solar Cells and Photoelectrosynthetic Cells Applications

EcoEnergy, EarlyView.
This review gathers examples of iron‐based photosensitizers that have been successfully immobilized on metal oxide surfaces for dye‐sensitized solar cells and potential dye‐sensitized photoelectrosynthesic cells applications. A critical comparison of Fe‐based photosensitizers is made based on their photophysical properties, electrochemistry, and ...

Nitrophenylsulfonyguaniden en hun splitsing door alkaliën [PDF]

, 1947
For preparing sulphaguanidine the reaction of p-nitrobenzenesulphochloride with guanidine in alcaline medium was examined. The controversy 1) which has arisen on the subject of this reaction has been proved to rest on incomplete examination.

Non‐Classical Nitrogen Promoters for Rhodium‐Catalyzed Reductive Hydroformylation: New Efficient Way to Access Polyols From Linseed Oil

European Journal of Lipid Science and Technology, EarlyView.
The reductive hydroformylation of linseed oil was carried out using a rhodium precursor associated with various nitrogen derivatives such as pyridines, imidazoles, trialkylamines, amidines, and guanidines. ABSTRACT The reductive hydroformylation reaction of polyunsaturated linseed oil using a rhodium precursor associated with a nitrogen compound from ...

2‐Formyl‐5‐(hydroxymethyl)furan (HMF) Derivatives as Active Complexing Agent for CO2 Insertion Reaction

European Journal of Organic Chemistry, EarlyView.
Renewable‐based furanics derived from 5‐HMF are used to synthesize cyclic organic carbonates (COCs) via CO2 insertion into epoxides. The BHTHF/NaBr complexing system shows high activity, achieving 94–99% epoxide conversion and 70–99% COC selectivity under mild conditions.

Targeting the Tumor Microbiota in Cancer Therapy Basing on Nanomaterials

Exploration, EarlyView.
Intra‐tumoral microbiota, which is a potential component of the tumor microenvironment, has been emerging as a key participant and driving factor in cancer. This article reviews the latest progress in this field, including the microbial community within tumors and its pro‐cancer mechanisms, as well as the anti‐tumor strategies targeting intra‐tumoral ...

Cataract‐Causing Mutant R188C of βB2 Crystallin With Low Structural Stability is Sensitive to Environmental Stresses and Prone to Aggregates Formation

Exploration, EarlyView.
This study investigated the role of the βB2‐crystallin c.562C>T (p.R188C) mutation in congenital cataract. Clinical pedigree analysis, combined with whole‐exome sequencing (WES), identified this pathogenic variant. Bioinformatic analyses predicted destabilization of the mutant protein’s tertiary structure, potentially impairing its function.

A Comprehensive Review of Starch: Structure, Properties, Chemical Modification, and Application in Food Preservation

Food Frontiers, EarlyView.
The negative effects of widely used polyethylene‐plastic packaging on environment and consumers' health along with the advantages of biopolymers lead to attention on active and degradable packaging as safe alternatives. Xie et al. thoroughly review starch, focusing on its chemical modification and application in constructing active and degradable ...
