Planar and Pyramidal Pentacoordinate Selenium Atoms

open access: yesChemistry – A European Journal, EarlyView.
Planar (D5h) and pyramidal (C5v) dianionic clusters, SeM5X52− (M = LiK; X = FBr), showcase pentacoordinate selenium atoms stabilized by geometric confinement and electrostatic interactions with surrounding alkali and halogen atoms. Abstract A systematic computational exploration of the dianionic systems SeM5X52− (M = Li─Cs; X = F─I) was conducted to ...

Sedimentary lithofacies, petrography and diagenesis of the Kapuni group in the Kapuni Field, Taranaki Basin, New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science with Honours in Earth Science at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2004
The reservoir architecture and quality of the Kapuni Group sandstones in seven wells (Kapuni−1, −3, −8, −12, Deep−1, 14 and −15) in the Kapuni Field are characterised using available core and digital geophysical log data.

Stimuli‐Responsive Chemical Systems That Mimic Biological Dynamics

open access: yesChemistry – A European Journal, EarlyView.
Chemists are designing synthetic systems that mimic life's dynamic behaviors, such as motion, sensing, adaptation, and compartmentalization, by integrating reaction networks with stimuli like light, pH, and chemical fuels. This mini‐review surveys molecular machines, responsive materials, nucleic acid networks, and artificial cells, highlighting how ...

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

Compositional Optimizations and Magnetic Performances of CoxFe3−xO4$${\mathrm{Co}}_x{\mathrm{Fe}}_{3-x}{\mathrm O}_4$$ Nanoclusters

open access: yesChemNanoMat, EarlyView.
This study reports the synthesis and compositional tuning of CoxFe3−xO4 nanoclusters (x = 0.6–1.4) via a controlled combustion route. Single‐domain particles exhibited systematically increasing coercivity and anisotropy with cobalt content. Peak saturation magnetization occurred at x = 1.2, while zero‐field cooling and field‐cooling and blocking ...

Properties of Bisdiazo Compounds and Their Derived Carbenes via Density Functional Theory

open access: yesChemPhysChem, EarlyView.
Density function theory (DFT) calculation at level of B3LYP‐(D3)BJ/6‐311G** reveals the fundamental electronic structure of substituted bisdiazo compounds as well as their derived carbene and biscarbene species at both ground and excited states. Extension to physisorption onto single‐layer graphene provides more insight of the surface behaviour of this
