Diamond is a highly desirable material for state‐of‐the‐art micro‐electromechanical (MEMS) devices, radio‐frequency filters and mass sensors, due to its extreme properties and robustness. However, the fabrication/integration of diamond structures into Si‐based components remain costly and complex. In this work, a lithography‐free, low‐cost method is introduced to fabricate diamond‐based micro‐resonators:...
Quantum dots light‐emitting diodes (QLEDs) have attracted much interest owing to their compatibility with low‐cost inkjet printing technology and potential for use in large‐area full‐color pixelated display. However, it is challenging to fabricate high efficiency inkjet‐printed QLEDs because of the coffee ring effects and inferior resistance to solvents from the underlying polymer film during the...
In article number 1900111, Wenming Su and co‐workers synthesize a crosslinkable hole transport material, 4,4′‐bis(3‐vinyl‐9H‐carbazol‐9‐yl)‐1,1′‐biphenyl (CBP‐V) for inkjet printing of quantum dots light‐emitting diodes (QLEDs). The inkjet‐printed CBP‐V film is smooth and flat. After thermal curing, an extremely dense and crosslinked solvent resistant film is formed. The function of this film for...
In article number 1805342, Susana Díaz‐Amaya, Lia A. Stanciu, and co‐workers study the performance of an optimized inkjet printing‐approach for nanopatterning of aptameric inks on nitrocellulose. The achieved optical detection of E. coli O157:H7 in real complex samples represents the lowest limit of detection reported to date.
The increasing incidence of infectious outbreaks from contaminated food and water supply continues imposing a global burden for food safety, creating a market demand for on‐site, disposable, easy‐to‐use, and cost‐efficient devices. Despite of the rapid growth of biosensors field and the generation of breakthrough technologies, more than 80% of the platforms developed at lab‐scale never will get to...
Flexible planar micro‐supercapacitors (MSCs) with unique loose and porous nanofiber‐like electrode structures are fabricated by combining electrochemical deposition with inkjet printing. Benefiting from the resulting porous nanofiber‐like structures, the areal capacitance of the inkjet‐printed flexible planar MSCs is obviously enhanced to 46.6 mF cm−2, which is among the highest values ever reported...
In article number 1902186, Nadja C. Bigall and co‐workers manufacture semiconductor nanoparticle‐based aerogel‐coated electrodes automatically via inkjet printing. By simultaneously printing a destabilization agent and semiconductor nanoparticles, a 3D aerogel‐type network on a conducting and transparent surface is obtained. Furthermore, the charge‐carrier mobility within the 3D aerogel‐type network...
Nanoparticle‐based voluminous 3D networks with low densities are a unique class of materials and are commonly known as aerogels. Due to the high surface‐to‐volume ratio, aerogels and xerogels might be suitable materials for applications in different fields, e.g. photocatalysis, catalysis, or sensing. One major difficulty in the handling of nanoparticle‐based aerogels and xerogels is the defined patterning...
