Progress in Flexible Perovskite Solar Cells: Paving the Way for Scalable Manufacturing
Advanced Materials Technologies, EarlyView.Perovskite solar cells (PSCs) are well positioned for a successful market uptake. This is due to an unprecedented improvement of their efficiency and stability since the first report in 2009. In this review paper, the building blocks for the scalable manufacturing and future commercialization of flexible PSCs and their pathway to impact will be ...

Stability criterion for fresh cement foams [PDF]
Cement and Concrete Research (2019) 125, p105865, 2019 We prepare and study cement foam samples with well-controlled structure, i.e. containing monodisperse bubbles. We observe that the foam structure often changes before cement setting and identify ripening as the major destabilization mechanism at stake.

Advanced Materials Technologies, EarlyView.This work demonstrates fluidic self‐assembly and self‐alignment of flip‐chips using a magnetic field for agitation and orientation. Pb‐free solder bumps with tailored transformation imprinted melting points enable selective capturing on low‐melting solder in water. After capturing, final alignment is achieved through magnetic forces.

Microleakage of orthodontic band cement at the cement-enamel and cement-band interfaces
American Journal of Orthodontics and Dentofacial Orthopedics, 2010 Our objective was to determine and compare microleakage patterns of conventional glass ionomer cement (GIC), resin modified GIC (RMGIC), and polyacid-modified composite for band cementation.Sixty freshly extracted third molars were randomly divided into 3 groups of 20 teeth each.

The Impact of DNA as a Chemical Admixture for Cementitious Materials
Advanced 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.
