Five people have died and six others are missing after an explosion and fire at a chemical plant in Gaomi, China on 27 May. The incident at Shandong Youdao Chemical injured 19 other people, according to reports in the South China Morning…

Voltammetric behaviour of thymoquinone on the carbon paste electrode

The preparation of the working electrode surface is a critical yet often underestimated step in achieving reliable and reproducible electrochemical measurements. The condition of…

Characterization of the prepared adsorbent

The elemental analyses of plant based cellulose acetate and PBCA–PVA particles are shown in Fig. 2a and b respectively. The EDX spectra of PBCA–PVA depicts a characteristically high peak of carbon,…

Infrared spectrum of acetone

The spectral signature of acetone in the MIR region includes several distinct absorption bands related to different molecular vibrations. Figure 4 shows the IR spectrum of a 100 ppm acetone sample without…

Simulation of the Flory-Huggins and Cahn-Hillard model effect on PIPS

The kinetics of the liquid-liquid state can be explained by a combination of expression for mixing energy from Flory-Huggins and system dynamics expression from Cahn-Hillard²⁵….

GBR model

Performance evaluation of a gradient boosting regression (GBR) model on training and testing datasets

As shown in the presented chart (Fig. 1), there are actual and predicted values of the GBR model for both training and testing…

Docking results

The SIK3 structure was used as a template to model the structures of SIK1 and SIK2. SIK1 shares 77.7% sequence identity and 58.0% sequence similarity with SIK3, while SIK2 shares 75.3% sequence identity and 58.4% sequence…

Clarivate, the owner of Web of Science, has said that this year it will start excluding citations to and from retracted content when calculating a journal’s impact factor.

The retracted articles will still be included in the article count to…

By stumbling upon a method for selectively fluorinating a skeletal C–H bond in the antibiotic ionophore salinomycin, researchers have been able to monitor its conformation with ¹⁹F NMR. ‘It was a serendipitous discovery – we did not predict…

Why ‘life is handed’ – why the chiral amino acids that make up proteins and the chiral sugars in nucleic acids are present only in one of the two possible enantiomeric forms – is one of the most tantalising questions for chemistry….
