Lung-on-Chip (LoC) are devices that give cells a habitat in vitro that tries to more nearly imitate their natural environment in vivo. This microscale bio-mimetic device is designed to replicate essential features of the human lung within a controlled environment. While advancements in microfluidic technology have been substantial, the lung-on...

Background: Treatment of eye conditions, such as retinal detachment, macular pucker or macular holes, ask for an intervention named ”vitrectomy”. In a vitrectomy, multiple surgical instruments are brought into the eye, to facilitate removal of the vitreous humor. The instruments enter the eye through trocar ports that are placed in the sclera....

Many semiconductor sensors, particularly MEMS sensors such as inertial, temperature, pressure, and resonance sensors need a vacuum environment for optimal performance and sensitivity in addition to the improvement in their long-term reliability. With the rise of heterogeneous integration with the MEMS and ICs being integrated together, process...

Bipolar electrosurgical vessel sealing is commonly used in human and veterinary medicine. This method of vessel sealing is often preferred over traditional suturing or clipping of blood vessels because it comes with the advantages of reducing intraoperative blood loss and operation time. Most bipolar vessel sealers are disposable. The high costs...

Thermoplastic compression resin transfer moulding coupled with injection moulding is an appealing process for the production of thermoplastic composites. However, its implementation at an industrial scale remains challenging as variotherm injection moulding could prevent solid skin formation in the parting line, making cavity sealing...

Glass bottles having a metal closure are preferred for oxygen sensitive beverages e.g. beer. Using thinner closure which comprise polyvinyl chloride-free component is more sustainable. However, protecting the sealing performance as a result of metal closure thickness reduction is challenging. Here we show the relation between the leakage in...

Seal area represents the most problematic part in food packaging for controlling the moisture and gas ingress and preserving product quality. Understanding the mechanism of heat sealing, which is a widely used method in flexible packaging, is critical for maintaining product quality throughout the storage and preventing food waste. Likewise,...

Bacteria-based self-healing concrete has the ability to heal cracks due to the bacterial conversion of incorporated organic compounds into calcium carbonate. Precipitates seal the cracks, theoretically increasing the service life of constructions. The aim of this paper is to propose a precursor for bacteria-based self-healing concrete derived...

Metal closures with a polymer-based sealing for beer bottles have been known since the late nineteen-sixties. However, to what extent which parameter of the polymer sealing gasket plays a role in closure performance to keep the beer quality to a highest level possible is not fully understood. For this purpose three thermoplastic elastomer ...

According to recent survey [1], about 6 billion people live in Low-and-Middle Income Countries (LMICs) who do not have proper access to safe surgical care. There are several reasons behind this, such as lack of funding to the healthcare department, below par maintenance of the available devices, poor infrastructure and most importantly high cost...

The current building environment has a lack of adaptability, which means that buildings are often demolished and rebuilt. In almost all cases, biological and technical materials are mixed by using glues, adhesives or wet seals, therefore materials can hardly be reused, if at all.<br/><br/>After demolishing, there are not always instantly new...

Study of self-sealing and self-healing in clay is a fascinating topic which can be applied in many fields namely in construction sector or as the underground nuclear waste repository. However, lack of references still hinders the advancement of such field. Meanwhile, more advance researches are available for self-sealing and self-healing in...

Windows are important elements in a building. They protect the interior from the exterior environment regarding weather conditions, noise, security and so on. While they also, in contrast to walls and floors, connect the two, creating links and providing rooms with daylight, fresh air and views in and out of the building. The most governing...

Rapid expansion of settlements and related infrastructures is a global trend that comes with severe environmental, economic, and social costs. Steering urbanization toward well-balanced compactness is thus acknowledged as an important strategic orientation in UN Sustainable Development Goal 11 (SDG-11) via the SDG-indicator “Ratio of land...

Ferrofluid rotary seals are mechanical contact-free magnetic liquid seals that are characterised by their simple structure, low friction and ability to hermetically seal. Although ferrofluid rotary seals for sealing vacuum and gases are part of a well established industry, the sealing of liquids has not been implemented yet. Literature learns...

Recently the concept of crack self-sealing has been investigated as a method to prevent degradation and/or loss of functionality of cracked concrete elements. To obtain self-sealing effect in the crack, water swelling admixtures such as superabsorbent polymers (SAP) are added into the cementitious mix. In order to design such self-sealing...

Despite theoretical predictions that graphene should be impermeable to all gases, practical experiments on sealed graphene nanodrums show small leak rates. Thus far, the exact mechanism for this permeation has remained unclear, because different potential leakage pathways have not been studied separately. Here, we demonstrate a sealing method...

In 2009 and 2010, two leakages through immersion joints occurred in the First Coen Tunnel near Amsterdam. From the study on t-he cause of these leakages, it followed that there was a potential problem for existing immersed tunnels: failure of the temporary Gina-seal combined with corrosion on the clamping structure of the definitive Omega-seal....

Seals are used throughout the technology spectrum to prevent products form leaving their container or preventing foreign products to enter. With the sealing of rotary parts like shafts the seal needs to not only provide sealing capabilities, but also simultaneously allow for the desired movement without too much friction or wear. This is often...
