This article describes the synthesis of a hydrophobic protective coating for concrete based on a silane derivative of fatty acids. The coating was obtained through a thiol-ene click addition reaction using methyl oleate and 3-mercaptopropyltrimethoxysilane in the presence of the photoinitiator 2,2-dimethoxy-2-phenylacetophenone (DMPA). This reaction proved to be more efficient compared with other tested (photo)initiators, considering the double bond conversion of oleate. The coating was applied to concrete using two methods: immersion and brushing. Both methods exhibited similar consumption of methyl oleate-based silane (UVMeS) at approximately 20 g/m². The hydrophobic properties of the coatings were evaluated based on the contact angle, which for the modified surfaces was above 93°, indicating their hydrophobic nature. The penetration depth of the silane solution into the concrete was also studied; it was 5–7 mm for the immersion method and 3–5 mm for the brushing method. The addition of tetraethoxysilane (TEOS) to the silane solution slightly improved the barrier properties of the coating.

Background: This article presents examples of how to utilize the research output, to initiate academia-industry interaction, with the ultimate task of launching a new product: a smart heart valve prosthesis for pediatric patients. The article summarizes our efforts in a way that may also be informative to researchers working in fields other than medical devices development. Our task is not to provide a step-by-step guide, but rather to create inspiration, also by describing differences in expectations of business and academic entities.Methods: We analyzed market reports, surveyed the scientific literature and conducted interviews with the key players in the field of medical devices. We also obtained a feedback from clinicians, academia and industry-related researchers, technology transfer centres, representatives of public organization and the creators of legislation.Results: We have obtained and reported the definitive answers that together constitute a critical review of strategies that should be used by researchers who seek to commercialize the outputs of their research.Conclusion: As a result of our investigation, we discovered that the commercialization of research is a complex process, which in some critical aspects does not depend solely on the researcher himself. The most promising ideas, supported by strong experimental evidence, can simply be overlooked by industry representatives, without the proper support of institutions such as a technology transfer centre. Besides, the involvement of scientists in a business project takes them, at least temporarily, outside the regular academic environment, which may cause discomfort and pose a risk to the career path. The limitation to be addressed is the reluctance to report the unsuccessful attempts, which should be considered a legitimate educational experience that ultimately leads to improvement.

The steady increase in the number of patients with diseased aortic valves demands the development of effective aortic valve replacement procedures. Engineering and technology offer various manufactured alternatives, but none can exactly match the natural human valve. In addition to the experts of heart valve tissue engineering, many researchers focus on specific aspects of the manufacturing of artificial valves. The aim of this study was to benefit such manufacturing processes. From the contributor's perspective, it is vital to gain comprehensive knowledge before embarking on this project. The perfect/optimal shape of the valve is the fundamental aspect that needs to be considered by all participants. It is noteworthy that the geometry not only limits the functionality of the structure but also determines the choice of material and engineering methods. In this study, we attempt to determine if current knowledge is sufficient to reach consensus on the issue of the optimum shape of the valve. Here, we not only provide a brief overview of traditional literature but also include the opinions of experts. This innovative way of scientific communication is unprecedented in scientific literature, and we hope that both professionals and contributors will find this study useful.
