The interaction between ionomer (ion-conducting polymer) and catalyst particles in porous electrodes of electrochemical energy-conversion devices is a critical yet poorly understood phenomenon that controls device performance. This interaction stems from the electrode precursor inks, which also governs porous-electrode morphology during formation. In this letter, we probe the origin interaction...

AIM This was to study the prevalence of dental fluorosis in a Swedish city (Uppsala) with natural 1-1.2 ppm F in drinking water. It was also to compare the prevalence of idiopathic enamel disturbances (Morbus S) in children born in Uppsala with the prevalence in children who had moved in to Uppsala at an age when the Uppsala water could not have influenced the development of Morbus S. METHODS...

3D-Reactive printing brings a new perspective for the 3D-printing of alginate-based inks. Printability was achieved through tuning crosslinking kinetics, without changing composition inks or use additives.

Material extrusion enables deposition of filaments with designed structures, and such sub-categories as direct ink writing brings increasing possibilities for the fabrication multi-material complex-shaped high-performance fully dense components. It has been well understood that critical requirement successful is printability inks. To address this challenge, a novel experimental approach takes a...

Fully exploiting the properties of 2D crystals requires a mass production method able to produce heterostructures of arbitrary complexity on any substrate, including plastic. Solution processing of graphene allows simple and low-cost techniques such as inkjet printing to be used for device fabrication. However, available inkjet printable formulations are still far from ideal as they are either ...

Organic Photovoltaics In article number 2300249, Antoine Bousquet, Natalie P. Holmes, Sylvain Chambon, and co-workers achieve power conversion efficiencies approaching 10% by careful control of the nanoparticle thin film morphologies thanks to surface energies considerations. This approach opens route low environmental footprint photovoltaics. Representing a promise this sustainable direction i...
