Progress in Flexible Perovskite Solar Cells: Paving the Way for Scalable Manufacturing

open access: yesAdvanced 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 ...

Magnetic Force‐Induced Self‐Assembly and Flip‐Chip Alignment on Electroplated Multilayer Solder with Tailored Melting Points

open access: yesAdvanced 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.

Setting control of completely recyclable concrete with slag and aluminate cements [PDF]

open access: yes, 2016
A completely recyclable concrete (CRC) is designed to have a chemical composition equivalent to the one of general raw materials for cement production. By doing so, this CRC can be used at the end of its service life in cement manufacturing without the ...

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.

Development of a Miniaturized Capillary Rheometer for High Shear Rate Rheology of Dense Suspensions

open access: yesAdvanced Materials Technologies, EarlyView.
This research presents a downscaled benchtop, low‐cost capillary rheometer that can characterize high shear rate rheometry of dense suspensions. The device is capable of measuring across a wide range of applicable shear rates using only a limited quantity of material and addresses a need for an accurate and affordable capillary rheometer.
