With a market demand for low cost, easy to produce, flexible and portable applications in healthcare, energy, biomedical or electronics markets, large research programs are initiated to develop new technologies to provide this demand with new innovative ideas. One of these fast developing technologies …

In this study, we experimentally investigated the material flows of coloured dyes in coalescing small inkjet printed droplets of different volume ratios. With two differently coloured dyes, one in each droplet, we were able to distinguish the time-resolved contributions in dye transport across the coalescence …

Nog nooit eerder was er een universeel medium als internet waar mensen met elkaar in contact konden komen. Waar internet eerst nog een bescheiden rol speelde, is het nu onderdeel van ons leven geworden. Door steeds meer online mogelijkheden worden technologie en internet vermengd met een aspect van alle …

Increasing oil and energy demand asks for higher efficiency when it comes to oil recovery. To increase oil recovery efficiency, pore-scale mechanisms during waterflooding, a common recovery method, have to be better understood. This provides knowledge on the dynamic process during imbibition, which …

Marine litter is cited by UNEP as “Any persistent, manufactured or processed solid material discarded, disposed of, or abandoned in the marine and coastal environment”, and includes metal, glass, paper, cardboard, processed wood, cloth and plastic. This report focuses mainly on the plastic fraction of …

Thirty years ago, in the summer of 1982, I was introduced to pediatric nursing during my internship in the Sophia Children’s Hospital, Academic Hospital Rotterdam (now Erasmus MC). One of my unforgettable patients was Dirk, a 24-year-old man with cystic fibrosis (CF), who spent his time in hospital in …

In this article we investigate the change in wetting behavior of inkjet printed materials on either hydrophilic or hydrophobic plasma treated patterns, to determine the minimum obtainable track width using selective patterned μPlasma printing. For Hexamethyl-Disiloxane (HMDSO)/N2 plasma, a decrease in …

Inkjet printing is a rapidly growing technology for depositing functional materials in the production of organic electronics. Challenges lie among others in the printing of high resolution patterns with high aspect ratio of functional materials to obtain the needed functionality like e.g. conductivity. …

A greenhouse with Fresnel lenses in the south facing roof and a receiver for concentrated Photovoltaics with water cooling (CPVT system) will result in electrical and thermal energy output from the solar energy excess entering a greenhouse. The PV system converts about half of the direct radiation into …

In this study, we present a new light absorption enhancement method for p-i-n thin film silicon solar cells using pyramidal surface structures, larger than the wavelength of visible light. Calculations show a maximum possible current enhancement of 45% compared with cells on a flat substrate. We deposited …
