Abstract:

The importance of the project goal arises from the rapid increase of packaging consumption and resulting waste, most of them being from synthetic polymers which are not biodegradable for hundreds of years. This project aims to replace the petrochemical based packaging materials with polymers derived from renewable biomass feedstock thus reducing the environmental pollution and providing simplified end-of-life disposal. This goal will be achieved through the use of biodegradable polyesters (polylactic acid (PLA), polyhydroxyalkanoates (PHAs)) and nanosized cellulose fillers (CN) isolated from a cheap source, namely fruit seed shell waste. Exploiting such inexpensive sources like crop waste for CN isolation and high value added products will contribute to solve the emergent problem of increased biomass and will reduce the cost of the new designed polymer nanocomposites. The new concept of “zero-waste” will be also demonstrated in this project. Innovative technological routes will be applied for the design of new advanced and fully renewable CN/biopolymers for packaging industry. Specific melt processing tests will be performed for developing high quality extrusion films and injected parts designated for niche packaging application, for example childcare products.

“New drug delivery systems based on micro/nanogel composites containing natural bioactive substances” Call name: Projects for Young Research Teams - RUTE -2014 call

Abstract:

The overall objective of the project consists of obtaining micro/nanoparticles of covalently crosslinked hydrogels based on polyethylene glycol and aliphatic polyamines (injectable micro/nanogels) having embedded both natural nanozeolites but also of natural bioactive substances in their polymer structure, with potential pharmaceutical applications. These new micro/nanogel composite structures are of great interest as they are aimed at being used as devices for subcutaneous or intravenous injection, ensuring the release of bioactive substances in hard-to-reach areas (by macroscopic hydrogels). The role of natural nanozeolites incorporation is to allow for a much slower and controlled release of the embedded active substances and to improve the viscoelastic features of hydrogels. Nowadays bioactive substances play an important role in the development of controlled release systems in medicinal chemistry for the production of new drugs with fewer side effects. The use of phytoextracts as bioactive substances is a big challenge of the project proposal. These new micro/nanodevices with controlled release will have significant influence, both nationally and internationally on the scientific, social and economic field. The results will be disseminated as follows: three articles published in ISI journals; three scientific communications at international conferences, and patenting of any original aspect.

Abstract:

Thematic area of the project proposal is in the field of functional foods destinated to maintain human health in concordance with research theme 5.1.6. Functional foods to maintain human health and prevent diseases, Domain 5. Agriculture, food safety and security.
The general project objective is to develop multifunctional and innovative products for protection of nutraceutical plants newly introduced in Romania (Momordica charantia and Passiflora incarnata) and to stimulate concomitantly formation of biologically-active compounds in these plants, at stable levels and with reproducible biological effects. The specific innovative project objectives are: 1. development of multifunctional for treatments of soil and in vegetation, based on: (a) consortia of Trichoderma strains; (b) porous ceramics with high bioavailability of silica; (c) essential oils included in mesoporous silica; 2. Testing products, developing methods of application and integrating them with the sustainable cultural technology of nutraceutical plants; 3. characterization of functional foods through in vitro alternative tests on human cell cultures and highlighting the biological role of silica forms accumulated in treated plants in animal cells; 4. results exploitation by protection of intellectual innovative solutions after techno-economical analysis and opportunities of results exploitation.
Products based on consortia of Trichoderma strains and essential oils have multiple actions as: plant protection agents towards biotic stresses (phytopathogens, pests), elicitors of plant defence response, limiting agents for the negative effects of ethylene on roots and growth promotor of plant nutrition, mainly with nitrogen.
Porous ceramics containing silicaxerogel, applied as soil treatment, work as a matrix for controlled release of nutrients with high bioavailability and have role to compensate losses of plant metabolic energy due to the synthesis of secondary metabolites and to supply orthosilicates with high bioavailability.
Silicon with high bioavailability supplies also mesoporous silica as a carrying for controlled release of essential oils. The silicon’s role as an important element for plants is to activate and balance - concomitantly and non-antagonistically – the different ways of plant defence system and of stress hormones biosynthesis (salicylic acid, jasmonic acid and ethylene/abscisic acid) in plant pathosystems.
This project proposes for the first time to study interaction of silicon, Trichoderma and essential oils treatments, protection agents with multiple roles, which activates simultaneously plant defence response. It is the first proposal aiming the development of some products with applicability directly into practice, in which silicon is controlled released from supports, having concomitantly the functional role as a matrix, from which nutrients and volatile oils are smart-delivered, in this why pointing out the possibility of practical use of silicon in order to balance the main signalling pathways in plant defence response, integrated with elicitors for obtaining high productions with raised phytonutrients level.
The highlight of silicon’s role in animal and plant organisms (having into account the unity in diversity of the life world), the (meso)porous silica forms as a support for controlled release of some active ingredients and of bioavailable silicon, compatibility of the Trichoderma consortia with the other products for the directed activation of plant resistance, will be the coagulation axis of this trans-disciplinary approach, revealing - also - the existence of synergies between partners in the frame of MAIA Project.

Abstract:

In principle thermochromic and thermotropic systems can function as energy saving systems. For high temperatures, during summertime thermochromic coatings have the ability to reflect solar energy, reducing the surface’s temperature; while in wintertime absorb solar energy, increasing the surface’s temperature as reversible color change takes place. Applied thus on external building surfaces, they have the potential for the reduction of heating and cooling loads, contributing to the reduction of urban temperatures, fight heat island and reduce air pollution.
Color-changing compounds have become increasingly important in recent years in the study and the production of thermochromic coatings that is coatings which respond thermally to their environment, changing reversibly their color from darker to lighter tones as temperature rises. The novelty comes from the use concomitant of thermotropic hydrogels which respond thermally by changing transparency from total transparent to translucent. Combining these features of termotropic hydrogels and thermochromic dyes we can obtain complex thermosensitive systems that respond to an increase in temperature by switching the color hypsochromically while accompanied by a change in transparency of the hydrogels.
During the project we intend to develop thermosensitive energy saving coatings that action on the entire Vis-NIR range and are most typically applied to roofs but additionally can also be applied to exterior and interior walls in much the same way. Thermosensitive coatings that will aim to obtain change reflectivity and color as a function of temperature, present enhanced weathering and durability and may be in any suitable formulation for application on roofs or walls such as water-based, oil-based, epoxy-based or acrylic-based formulations.
