Derivatives synthesis and assessment of flocculation efficiency

Structures 1–5 were synthesised through a two-step procedure²⁷ (Fig. 2). First, the corresponding bisbenzaldehyde was prepared by treating the corresponding α,ω-dibromoalkane…

Characterization of GO and rGO

The XRD pattern was analysed for a qualitative assessment of the as-prepared GO and rGO Fig. 1(a). GO displays a distinct peak at 8.5°, attributable to the (001) diffraction peaks of GO, resulting from the presence…

If you could take a molecular-level look at anything at all, what would you choose? Your favourite food? A bird feather? Or maybe even a dinosaur fossil?

Techniques like electron microscopy and mass spectrometry are usually the preserve of…

For the first time, researchers have synthesised and characterised the ‘only possible structure’ with four hydroxyl groups linked to a carbon atom – methanetetrol.

Also known as orthocarbonic acid, this molecule was first hypothesised…

‘An act of national self-harm.’ That’s how the House of Lords science and technology committee describes the UK’s approach to attracting global Stem talent. The government insists it wants to attract the best researchers into the country,…

A decade after concerns about the necessity of testing for alkyl sulfonate esters in drugs were raised¹, risk assessment for this potentially mutagenic contaminant is still required by UK and European drug standard authorities.² Other major…

The effect of temperature on bio-oil upgrading

Effect of temperature on product composition and yield

Reaction temperature is a critical factor that significantly influences the yield and composition of the products. The compositional distributions…
