Surface characterization study on SnO2 powder modified by thiourea
, 2005 The SnO2 material prepared by sol-gel method was modified by thiourea solution in different concentrations (0.05, 0.1 and 0.2 mol dm(-3)). Then the structure and the average grain size of the SnO2 material were investigated by X-ray power diffraction. In

Stereochemical Control in the Matteson Reaction
Chemistry – A European Journal, EarlyView.The Matteson homologation is a highly versatile method for the stereoselective insertion of carbenoids into boronic esters. Through iterative application of the process, complex chiral molecules can be synthesized. The stereoselectivity of the reaction is determined by a chiral diol incorporated in the boronic ester.

Chemistry – A European Journal, EarlyView.Hybrid macrocyclic peptides unite genetically encoded peptide libraries with the structural complexity of synthetic small molecules. This Review critically analyzes phage‐compatible cyclization and diversification chemistries, highlights emerging opportunities beyond traditional cysteine‐based approaches, and outlines how future advances may enable the

Chemistry – A European Journal, EarlyView.A molecular design strategy combines lignin‐derived aromatic units, sugar‐derived furan groups, and flexible glycol segments to create wet‐spinnable polyurethanes. Thermally reversible Diels–Alder crosslinking chemistry enables formation of crosslinked thermosetting fibers, repeated de‐crosslinking/re‐crosslinking cycles, and tunable fiber properties ...

Chemistry – A European Journal, EarlyView.Regioisomerism rewires orbital topology and electronic polarity in curved non‐alternant π‐systems, switching both optical response and alkali metal ion recognition from Na+ to Rb+ selectivity. ABSTRACT Herein, we explore the fundamental concept of combining the molecular curvature of a molecular fragment of buckminsterfullerene with the pronounced ...

Zebrafish inversin mutants develop scoliosis in the absence of laterality defects
Developmental Dynamics, EarlyView.Abstract Background Human mutations in INVERSIN are associated with nephronophthisis, variable penetrance of situs inversus and congenital heart disease. Inversin has been shown to localize to cilia and many of the patient phenotypes are attributed to disrupted cilia function.

Zebrafish ventral gastrula fate map reveals neural crest progenitor domain
Developmental Dynamics, EarlyView.Abstract Background Fate maps relate progenitor cell positions to later fates and locations of their progeny, revealing early embryonic organization. Previous zebrafish fate maps identified the origin of germ layers and derivative cell fates, but ventral gastrula progenitor domains were not fully resolved. In particular, the neural crest, a multipotent

Thiourea - Lanthanide Acetate Complexes [PDF]
, 2001 Complexes between thiourea and lanthanide acetates were prepared of the general composition. Dihydrated thiourea complexes are isomorphous; monohydrates are also isomorphous, but with a different structure from the dihydrates.
