Additive Manufacturing (AM) technologies are one of the major trends in the world of new technological solutions. They are often considered to be one of the fundamental building blocks of the Fourth Industrial Revolution. The use of computer-aided design (CAD) to create three-dimensional models with complex geometries without material waste takes t...

Hydrogels are three-dimensional cross-linked polymeric networks capable of a large amount of fluid retention in their structure. Hydrogel outputs manufactured using additive manufacturing technologies are exposed to water loss, which may change their original shape and dimensions. Therefore, the possibility of retaining water is important in such a...

The application of additive manufacturing (AM) technology in biomedicine offers many advantages due to the possibility of personalization and precision in shape accurate reproduction or dose of drug selection. AM technique enables the use of a wide variety of biocompatible materials, which can be applied even in the form of hydrogel. However, the u...

Objectives The paper presents preliminary results on the assessment of algorithms used in image processing of the grain damage degree. The purpose of the work is developing a tool allowing to analyse sample cross-sections of rye germs. Methods The analysis of the grain cross-sections was carried out on the basis of a series their photos taken at e...

Hydrogels are cross-linked polymeric structures, which consist of up to approximately 90% water, the remainder is polymer chain. Retention of large volumes of water in the intermolecular space is related to the presence of hydrophilic functional groups in the network. The unique hydrogels properties, such as porosity, and biological and mechanical...

Cancer is a significant public health problem worldwide, therefore it is important to find appropriate treatment methods. In addition to surgical treatment, chemotherapy, and radiotherapy, drugs are increasingly employed. Drugs and their delivery systems have a significant role in the treatment of cancer, hydrogels find wide application there. Hydr...

Sustaining the vital functions of cells outside the organism requires strictly defined parameters. In order to ensure their optimal growth and development, it is necessary to provide a range of nutrients and regulators. Hydrogels are excellent materials for 3D in vitro cell cultures. Their ability to retain large amounts of liquid, as well as their...

Alginate is a polysaccharide naturally occurring in brown seaweeds cell walls. Unique properties such as ease of gelation, biodegradability, biocompatibility, and non-toxicity of alginates make them widely employed in a variety of industries. Mentioned here properties and versatility of alginate resulted in approval by U.S. FDA (Food and Drug Admin...

At the moment it is hard to imagine the first colony on Mars, the first settlements, even though the city per million inhabitants. Although the first manned flight to Mars is approaching, our InnSpace team would like to present today the futuristic concept of a state on Mars for 1,000,000 inhabitants, designed for the Mars City State Design competi...

Searching for an alternative planet to be inhabited by humans is currently quite a popular topic, especially considering the current state of technology development and future opportunities. Mars is the closest planet in the Solar System, located in the ecosphere, which despite the difficult conditions on the surface, is planned to be colonized. Ho...

The project of a city per thousand inhabitants performed in the Mars Colony Prize competition

Life on Mars seems to be getting closer to us. We are currently not asking whether it will ever be possible, but rather determining the real date. We need to design the entire infrastructure, resistant to previously unknown problems such as radiation, strong sandstorms or low temperatures. Fortunately, the longer we study the red planet, the more o...

Mars is the natural direction of space expansion. It is a trend that we consider Mars as not only a planet where we want to take the first step, but a place where we could live in the future. This would be another step for humanity, which would help us to become an interplanetary species. However, it is necessary to carefully prepare such an ambiti...

Taking into consideration a permanent Mars colony, it is extremely important to ensure proper production of goods. We can not base human life on the continuous supply of elements from the Earth, we should aim at the self-sufficiency of the inhabitants.
