Noninvasive Glucose Detection with Biodegradable Electrodes from Rice Starch Functionalized with a Carbon Quantum Dot/Nickel Oxide Nanocomposite

open access: yesAnalysis &Sensing, EarlyView.
The graphical abstract shows an eco‐friendly approach to fabricating a biodegradable electrochemical sensor. Carbon quantum dot/nickel oxide (CQD/NiO) nanocomposites are synthesized using Aloe arborescens leaf extract, which served as a natural reducing and stabilizing agent.

Polydopamine‐Mediated Silver and Nickel Metallization of Phase Change Microcapsules for Multifunctional Flexible Epoxy Composites

open access: yesJournal of Applied Polymer Science, EarlyView.
An eco‐friendly, polydopamine‐assisted electroless metallization of phase change microcapsules enables thin silver or nickel coatings that preserve phase‐change functionality and while enhancing thermal diffusivity and thermomechanical performance in flexible epoxy composites.

Modification of the Solid Electrolyte Interphase on SiGr Electrodes by a Prelithiation Method Using Passivated Lithium Metal Powder

open access: yesBatteries &Supercaps, EarlyView.
Prelithiation of SiGr electrodes by direct contact with passivated lithium metal. powder creates a solid electrolyte interphase (SEI) layer prior to cycling which is superior to the one conventional SEI layer produced during the formation cycles in nonprelithiated cells.

Influence of the surface roughness on the fatigue properties in ausferritic ductile irons (ADI)

open access: yesMATEC Web of Conferences, 2014
Heat treatment of cast ductile iron (DI) to ausferritic ductile iron (ADI) is known to increase fatigue properties. However, the surface roughness of the cast material is also of significant importance.

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

The abrasion of austempered cast iron in laboratory and work conditions

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2005
Austempered ductile iron (ADI) is nowadays used for machine parts, which used to be made of steel. It is suitable for abrasive conditions and cast irons exhibit sufficient strength and toughness.
