Abstract:

The orthodontic therapy has been in great demand worldwide in recent decades to treat dental and malocclusion problems with a focus on removable orthodontic appliances (ROA) among children and teenage patients. Besides their beneficial role in treating dental disorders, ROA may create a favorable environment for the proliferation of pathogenic microorganisms and the formation of biofilm on the surface of the orthodontic appliance. The general objective of the Waste2Coat project is the conversion of bio-waste from microalgae cultivation, containing polysaccharides, into new sustainable and functional biomaterials with antibacterial properties for orthodontic engineering. Despite the impressive progress in the biomaterials field, the proposed materials, both in terms of composition and design, represent an uncovered niche in the ROA treatments. The new biomaterials that will be developed in the frame of the Waste2Coat project, in the form of biocoatings, micro-implants, and scaffolds, will reduce the incidence of caries and other periodontal diseases caused by the use of ROA thus improving the safety of these orthodontic treatments.

Abstract:

Severe oxygen deprivation can cause significant problems in chronic wounds, during organ preservation and implantation, or in cases of trauma, hemorrhagic shock, or viral pneumonia. Oxygen prevents wound infection, increases cell viability after implantation and could be an effective treatment in viral pneumonia. Currently, there is no viable solution to deliver oxygen to the grafts during the healing period and to administrate a large volume of oxygen to patients who suffered profound oxygen deprivation. The scope of the CELGAS project is to develop innovative oxygen-carrying systems capable of supplying oxygen in a controlled manner to injured tissue/ implants or intravenously. The innovative oxygen-carrying systems will ensure controlled release of oxygen for long periods of time, will have a high stability, biodegradability, will not be cytotoxic and will have a nanometric size, essential for intravenous administration to avoid vascular obstruction. In CELGAS, the problem will be addressed using nanocellulose and nanocellulose/biopolymer to encapsulate oxygen-generating species or to obtain oxygen-containing nanobubbles. The biopolymers to be used are selected from poly (3-hydroxybutyrate), medium chain length polyhydroxyalkanoates and polylactic acid. The design of the new systems will be based on improved methods and an efficient characterization that will allow the achievement of the objectives.

Abstract:

SPARACOM is a complex solution for the transfer to the economic operator, in order to increase the competitiveness of the economic environment and the assimilation of market-oriented RDI results. The consortium involves the collaboration between an innovative company and a large research institute in the field. The proposal aims at the efficient maximization of the financing instrument (technological maturation of TRL4 to TRL6; it starts from the technology validated within PN-III-P2-2.1-PED-2016-1332, 84PED, financed by UEFISCDI; the use of an infrastructure at international level; SMEs with high innovative potential; avant-garde technological solution, an opportunity at the level of the international market; connecting national applied research to the national and international market). The budget is balanced by allowing adequate and flexible resources for better management and contingency plans. To maximize the final results some activities and budgetary resources from outside the project are committed to increase the visibility and impact of research. The CO and P1 research team implies an important institutional character: members from several departments and research teams together with the valorization of competencies. The technological approach involves advanced hybrid antifouling systems (and acting in a sequential mode) but also a self-repair system with potential in freshwater and marine environments (a major challenge in the field). The expected results involve both TRL technology and at least: a paper at scientific events, a paper sent for publication to an ISI publication, a patent application, a web page.

Abstract:

Chronic wounds, severe burns or infected wounds are among the most painful diseases that require long-term expensive treatment. Currently, the clinical management of chronic wounds is difficult due to the increasing risk of infection with antibiotic-resistant bacteria and the shortcomings of current therapies. A novel technology for the manufacture of bilayer wound dressings, based on nanocellulose and cold plasma processing, will be developed in BIOPLASM project. The scope of the project is to obtain effective dressings for the treatment of infected wounds by developing antibacterial nanocellulose nanocarriers deposited on an aliphatic polyester substrate.

The use of cold plasma for nanocellulose and biopolymers processing in view of medical application is an effervescent field, with important benefits related to eco-friendliness, lack of secondary or waste products, sterilization and large functionalization capabilities. Cold plasma treatment of liquid suspensions of nanocellulose is a concept developed by ICECHIM and INFLPR in a previous project. This will serve as a starting point together with the functionalization and processing of nanocellulose and aliphatic polyesters for building a new technological approach to fabricate bilayer wound dressings. The new technology will be validated by in vitro and in vivo studies. The project will be implemented by a skilled group of researchers from ICECHIM, INFLPR and Cantacuzino Institute.

Project website: https://icechim.ro/project/epocel/

Abstract:

Epoxy resins are being used in many key applications of the automotive manufacturing industry due to their properties such as high thermal stability, mechanical strength, moisture resistivity and adhesion. Although these materials have a high performance in electronics their end-of-life disposal raised tremendous global environmental concerns. Thus, designing novel biomaterials able to overcome these disadvantages have become an important goal for the scientific community.

The proposed project aims to develop new nanocomposites, based on renewable and inexpensive biological sources, with thermo-mechanical balanced properties for applications in electronics (EPOCEL). The goal of this project will be achieved through the use of renewable resources like vegetable oils and different nanocellulose fillers to obtain the epoxy systems. The EPOCEL nanobiocomposite materials will exhibit a tailored interface design which will assure performances comparable to those of petroleum-based but at a lower price. The project approach is based on the association of materials produced from regionally low cost agricultural feedstocks which will be employed for the development of novel materials with high - added value. Various epoxy system components and different agents for nanocellulose functionalization will be screened for achieving the desired thermal and mechanical performances. Nanocellulose will have a significant role in providing biodegradability besides controlled stiffness.

The assessment of the EPOCEL model for electronics will be made after detailed analysis of physico-chemical, mechanical and thermal properties.

Project website: https://icechim.ro/project/flex4pla/

Abstract:

The present project fits into the stream of study and characterization of biobased materials, considering the need to improve their properties from a technological point of view to allow their wider use in final products. Currently, biopolymers have found applications in fields starting from packaging to automotive but an almost unexploited market segment is represented by materials intended for children goods. Most of the global produced toys and other goods for children are made with conventional plastics derived from non-renewable petrochemicals containing dangerous chemical additives to ensure flexibility, natural feel and easy coloring. Thus, the FLEX4PLA project aims the research and design of new biomaterials in which both polymers and additives are being derived from renewable resources. The approach of FLEX4PLA consists in the synthesis of new bioelastomers compatible with PLA from biobased resources and the design of a new technological route to ensure nanodispersion and an engineered interface in PLA/bioelastomers nanomaterials. The new nanomaterials will exhibit the good elasticity of the bioelastomer and the excellent processability of PLA and no more that 10% decrease in strength compared to neat PLA. Tensile properties, impact tests, melt flow index, fracture behavior and morphology will be performed in order to characterize the new biomaterials with the aim of correlating the composition to processability and thus establishing the final properties.
