Practical assessment of masonry tunnel joint segmentation using topological machine learning

Civil Engineering Design, EarlyView.
Abstract Condition assessment of masonry lined tunnels is time consuming and labor intensive. Recently developed digital workflows enable structural models to be created automatically, reducing analysis time. As part of these procedures, it is important to be able to identify the location of each masonry block.

Probing Effects of Electron Addition to Polycyclic Conjugated Hydrocarbons Containing Four‐Membered Rings

ChemistryEurope, EarlyView.
Studies of the mono‐ and doubly reduced cyclobutadienoid derivatives with increasing conjugation length reveal that the two‐electron addition does not allow the four‐membered rings to achieve the aromatic square shape, instead resulting in the distorted rectangular or trapezoid geometries, even at the cost of losing aromaticity of the fused benzenoid ...

Total Synthesis of Kanamycins

Chemistry – A European Journal, EarlyView.
This paper reports on creating a novel synthetic route of kanamycins A and B using the desymmetric boron‐mediated aglycon delivery (BMAD) reaction of meso‐diol acceptor with 1,2‐anhydro donor and regio‐ and stereoselective glycosylation of diol acceptor with trichloroacetimidate donor for introduction of a set of challenging 1,2‐cis‐glycosidic linkages

Recent Advances in Polyoxometalate‒Metal Nanocluster Hybrids

Chemistry – A European Journal, EarlyView.
POMs are gaining attention in metal nanocluster synthesis for their ability to impart unique structural and functional roles. This review highlights recent advances in POM–metal nanocluster hybrids, categorized as follows: (a) hybrids of POMs and metal nanoclusters stabilized by organic ligands, (b) metal nanoclusters stabilized by POMs as ligands, and
