Migrant workers in Vietnam make up 7.3 per cent of the population. Despite rapid economic growth, they suffer from precarious working conditions and food insecurity, which Covid-19 control measures have exacerbated. Urgent action is needed to improve

Curing of epoxy–amine resins with bisphenol A (BPA) as an external catalyst was studied from differential scanning calorimetry analyses in isothermal and dynamic modes. Both phenomenological and mechanistic models have been tested. The mechanistic

Model-free and model-fitting kinetic approaches were applied to isothermal and nonisothermal DSC data on epoxy cure. The dependence of the effective activation energy on the extent of cure was determined using integral and differential isoconversiona

The cure kinetics of a DGEBF/DGEBA mixture with a commercial aliphatic amine mixture [poly(propylene) oxide diamine D230 and diethylene triamine (DETA)] was investigated by DSC. Two types of kinetic models based upon the formation of amine-epoxy-hydr

Two analytical methods were developed to characterize the fate of bisphenol A (BPA) added in low amounts (1–4 wt%) in two different epoxy–amine–BPA systems, one based on a mixture of aliphatic amine curing agents, diethylene triamine (DETA) and

We have prepared iron doped TiO 2 samples by the impregnation of TiO 2 (Degussa—P25) with Fe(III) nitrate as an iron precursor. Obtained materials were then characterized by structural x-ray diffraction (XRD) and optical (Uv-vis, Raman) techniques.
