The Impact of DNA as a Chemical Admixture for Cementitious Materials

open access: yesAdvanced Materials Technologies, EarlyView.
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.

Electrochemical‐Doping of Tungsten on Nickel‐Boron‐Phosphide Microspheres for Accelerated Industrial‐Scale Water Electrolysis at High Current Density

open access: yesAdvanced Materials Technologies, EarlyView.
The bifunctional W/NiBP (+) || W/NiBP (−) demonstrates superior overall water splitting (OWS) performance as compared to the benchmark of Pt/C (+) || RuO2 (−). Notably, the W/NiBP (+, −) exhibits an ultra‐low cell voltage of 2.68 V at 2000 mA cm−2 high current density as compared to the benchmark value of 3.29 V.

Advances and Outlook of Nickel‐Based MOFs–LDHs Materials for Energy Conversion

open access: yesAdvanced Sustainable Systems, EarlyView.
In this graphical abstract, we present the pivotal gap between the activity and stability parameters as far as intergrated Ni‐based MOF/LDF electrocatalysts are concerned. For large scale application, these two parameters should be optimized and furthermore balanced in order to promote sustainable electrocatalytic hydrogen production.
