The Impact of DNA as a Chemical Admixture for Cementitious Materials

open access: yesAdvanced Materials Technologies, Volume 10, Issue 15, August 7, 2025.
DNA molecules are added to cement pastes and their effects on rheology and hydration time are studied. DNA's chemical structure is composed of polysaccharide and phosphate groups, which are active functional groups in different commercial chemical admixtures: Viscosity modifiers and superplasticizers.

Maglev train levitation control via tracking differentiator with small phase lag

open access: yesIET Control Theory &Applications, Volume 19, Issue 1, January/December 2025.
This work proposes an enhanced tracking differentiator to ensure a small phase lag in both filtering and differential signals, The favourable characteristic is obtained by including the system damping and the amplitude factor into the control algorithm that is applied to construct the differentiator. Abstract The levitation control system is a critical
