Precipitation of niobic acid from potassium niobate in sulphuric acid solution: A route to niobium oxide

The Canadian Journal of Chemical Engineering, EarlyView.
Graphical abstract illustrating the niobic acid precipitation process applied and the product obtained. Abstract This study investigates the precipitation of niobic acid (Nb2O5.nH2O) from potassium niobate solution with addition of sulphuric acid, and its subsequent thermal conversion into niobium oxide (Nb2O5). Thermodynamic modelling with PHREEQC and

Protocol for Reconstituting Adaptor‐Mediated Activation of Full‐Length Kinesin‐1

Cytoskeleton, EarlyView.
ABSTRACT Kinesin‐1 is a member of the kinesin superfamily that plays an essential role in intracellular cargo transport. In the absence of cargo, Kinesin‐1 exhibits low motor activity due to autoinhibition. Multiple studies have demonstrated that adaptor proteins, which link cargos to Kinesin‐1, can activate Kinesin‐1 by releasing the autoinhibition ...

Evolution of the water cluster in pore condensation

Droplet, EarlyView.
In pore condensation, lower contact angles reduce molecular displacement (60%) and potential energy (10%), enhancing vapor capture tenfold. Pores restrict water molecule mobility, promoting condensation. On hydrophobic surfaces (124∘$^\circ$), pores stabilize embryos, ensuring uniform condensation within pores, boosting nucleation efficiency.

Elucidating the polycyclic aromatic hydrocarbons involved in soot inception

Communications Chemistry, 2023
Polycyclic aromatic hydrocarbons are the main precursors to soot particles in combustion systems. A lack of direct experimental evidence has led to controversial theoretical explanations for the transition from gas-phase species to organic soot clusters.

A study on the influence of inorganic ions, organic carbon and microstructure on the hygroscopic property of soot [PDF]

Atmospheric Chemistry and Physics
Soot is a crucial component of aerosols in the atmosphere. Understanding the hygroscopicity of soot particles is important for studying their role as cloud condensation nuclei (CCN) as well as their chemical behavior and atmospheric lifetime.

The Illusion of Structural Order: Evaluating the Suppression of Amorphous Carbon Black Pigment Bands in SSE‐Processed Handheld Raman Spectra

Journal of Raman Spectroscopy, EarlyView.
The handheld Raman with SSE system efficiently mitigates fluorescence; however, it may also bias the Raman response towards graphitic domains in carbon‐based black pigments, thereby concealing amorphous carbon contributions that are critical for pigment type identification.
