Single‐Step Synthesis of Dithieno[3,2‐b:2′,3′‐e]Pyridines and Their Acid‐Dependent Optical and Photosensitising Properties

open access: yesChemistry – A European Journal, EarlyView.
The synthesis of dithieno[3,2‐b:2′,3′‐e]pyridines (DTPs) is herein reported, and their optical properties are studied both experimentally and computationally. Protonation or methylation of the nitrogen atom induced bathochromic shifts in their absorption and emission spectra.

Post‐LECA Origin and Diversification of an Axonemal Outer Arm Dynein Motor

open access: yesCytoskeleton, EarlyView.
ABSTRACT Dyneins were present in the last eukaryotic common ancestor (LECA) and play key roles in eukaryotic biology. Axonemal dyneins form the inner and outer arms that power ciliary beating, and it has long been recognized that outer arms in some organisms contain two different heavy chain motors, whereas those from other species contain a third unit

Shear behavior of bolt–grout interfaces under constant normal stiffness: Influence of grout strength and thickness

open access: yesDeep Underground Science and Engineering, EarlyView.
The effects of grout strength and thickness on the shear behavior of bolt–grout interfaces (BGI) under constant normal stiffness conditions are investigated. Shear strength, failure modes, and acoustic emission characteristics are examined. The findings reveal that grout strength exerts a significantly greater influence on BGI shear strength and ...

Experimental study on burning rate and flame geometry in construction tunnel fires under high geothermal conditions

open access: yesDeep Underground Science and Engineering, EarlyView.
Abstract As tunnel construction advances in lengths and depths, the construction of tunnels in high geothermal environments has become increasingly common, raising significant fire risks. In this study, a 1:20 scale model tunnel test platform was constructed to investigate the effects of a high geothermal environment on fire behavior in tunnels during ...
