Abstract:

Lactic acid(LA) has attracted a significantly attention of the researchers due to its wide application in food processing and preservation, pharmaceutical and cosmetics industries and mainly in the synthesis of the polylactic acid. The production of LA in the presence of the heterogeneous acid catalysts attracted the attention of researchers because they are environmentally more sustainable according to the principles of green chemistry. Taking into account the previous studies published, the water-tolerant nature of niobium(V) Lewis acid sites, the strong metal support interaction properties of titanium oxide with transition metals, the existence of Lewis and Brønsted acid sites on the surface of niobium oxide as well as the catalytic activity of titanosilicates in the production of lactic acid derivatives from sugars we propose in this project to validate the process for the synthesis of Nb-based catalysts for the first time to the best of our knowledge, such as niobium doped titanium oxide prepared by solution combustion synthesis, Ti-silicalite-1 with MFI framework and bimodal pore systems (micro-/mesoporosity) supported niobia and activated carbon (obtained from spent ground coffee) supported titanium and niobium oxides and to develop also an experimental model for one-pot conversion of cellulose into lactic acid over Nb-based catalysts,aforementioned, at laboratory scale.

The prepared materials will be exhaustively characterized by using different several techniques such as Pyridine-FTIR, NH3- TPD, XRD, BET, XPS, SEM-EDX, TEM, TG/DTA with the aim to establish a physico-chemical characteristics - catalytic performances correlation in the synthesis of LA from cellulose. Parameters such as: the effect of the amount of catalysts tested, reaction time, reaction temperature will be explored in order to optimize the cellulose conversion to LA.

Abstract:

The project proposal "Transfer of innovative co-crystallization technologies for the development of nutraceutical functional products -INOCRYSTAL", aims to (i) validating a functional model for the preparation of nutraceutical functional products obtained by (ii) innovative technologies based on the co-crystallization of resveratrol and piperazine and (iii) strengthening TeraCrystal's innovation capacity in obtaining new products with nutraceutical properties for the livestock sector, both for the domestic and foreign markets. This project proposal capitalizes on the results of its own research, obtained through the collaboration between the two partners (TeraCrystal srl and the Institute of Physical Chemistry of the Romanian Academy) and materialized by obtaining an international patent (US 20210032210A1). Based on the results obtained at laboratory scale, a functional model (TRL5) is proposed, which involves cocrystals obtained by the homogenization/milling technique of resveratrol and piperazine in the presence of ethyl alcohol. A discontinuous technological process is used with 2 kg rods. It can be estimated that the product thus obtained possesses nutraceutical functions and generates a profit of 30.000 euro/month for a 100kg production. It is also proposed to patent the technology for obtaining the nutraceutical product and to disseminate the results by participating in two international conferences and publishing three ISI listed papers.

Abstract:

The cultural heritage, as a source of national historical and cultural authenticity, is subjected to deterioration, and for stopping it, some specific procedures are required: cleaning, replacement of old materials and application of new protective materials compatible with the original, and advanced monitoring with sustainability assessment. The consortium of the present project has a unique expertise in Romania, recognised in Europe, through the many published papers, essential projects in Romania (Basarabi Churches, Potlogi Palace, etc.), OSIM and EPO patents, technology transfer, nanomaterials in chemical and biological preservation for cultural heritage objects and objectives; the partner institutions complement each other on a regional basis in the working plan of the whole project.

The overall objective of the project is to develop new materials, new methods and technologies that obey the principles of authenticity, reversibility and value, with a strong impact on immobile cultural heritage objects (fresco, basreliefs and mosaic) and mobile (decorative artefacts from ceramics, glass, metal, bone, objects of art and archaeology). Specific objectives: Developing innovative technologies for protecting national cultural heritage, multidisciplinary cross-sectoral approach, encouraging young professionals as leaders in heritage preservation, exploitation of research results for new jobs, promoting heritage education, professional expertise among all factors involved in the patrimony protection system.

The project, with a high degree of innovation and originality, applies unique technologies in Romania based on new materials compatible with the original materials and develops new techniques practical applied to: Roman Mosaic and Hypogeum Tomb, Constanta, Adamclisi Museum (basreliefs), Constanta County, Corvin’s Castle (Fresca Loggia Mathia) and Archaeology Museum, Hunedoara.

Abstract:

The project aim is to obtain hybrid materials in form of enzymes/1D oxide nanostructures for enhancement of biodegradation process rates, leading to increased soil fertility. In order to achieve this scope, SiO2 (SiO2_NT) and sodium titanate nanotubes (TiNTs) will be functionalized with extracellular proteases, lipases and amylases of halophilic/halotolerant microorganisms isolated from Romanian saline environments, i.e. saline soils and lakes. Exoenzymes will be isolated, purified, biochemically characterized and immobilized on inorganic support (SiO2_NT and TiNTs). The efficiency of the hybrid materials will be tested for their biologically activity in native enzymatic form. The ability of the novel hybrid structures to contribute at the accelerating rate of biodegradation in experimental soil models will be also evaluated. The project is looking for obtaining reproducible data regarding the enhancement of enzymatic activity obtained by immobilization of extracellular protease, amylase, and lipase on tubular matrix of SiO2 and TiNTs. These results are meant to be a useful support for the biofertilization of intensively exploited or salted soils. Our project proposal is focusing on: (a) optimization of the textural properties of inorganic matrices (SiO2_NT and TiNTs) with respect to the further enzymatic immobilization; (b) modification of tubular surfaces with chemical active species in order to improve the enzymatic immobilization; (c) isolation of halophilic strains for targeted exoenzymes extraction; (d) tests regarding the adherence/adsorption of enzymes; (e) enzymatic tests with application in soils biofertilization.

Abstract:

The AWARE project topic is to establish an advanced conducting technique of controlling a clinker kiln operation in condition of waste recovery. The project topic lies within the 7.2 research area – advanced technologies to conduct industrial processes in the framework of the 7th domain – materials, processes and innovative products.

Due to a large number of variables which has an effect on both kiln operation and the quality of the clinker, is difficult to optimise the kiln operation, particularly due to variations in the feed material, fuel quality, burning conditions and other variables. Optimization is thus simply difficult to achieve manually or partially automated. The difficulty in manual or partially automated control is partly due to the difficulty in ascertaining what is going on inside the kiln, from both a process and a metallurgical point of view. This is practically a general problem, which is especially accentuated in high temperature systems where direct continuous industrial temperature measurement does not exist. Since, remnant features present in the clinker microstructure depend on the kiln feed variations and the burning conditions is understandable the strength of descriptive methods for particle shape and morphology quantification in optimization the clinkering process.

In order to overcome the above-mentioned issues CEPROCIM, UPB, ICF and CARPAT decided to join their efforts and skills in order to develop a solution to the problem of optimisation a process with a large number of variables which affect the operation of the kiln and the quality of the clinker. The practical purpose of the AWARE project is to implement the developed solution in a cement plant, which is the 3rd partner in the consortium.

In the AWARE project the research effort will be focused in the development of two end-products: a clinker microstructure model for high level control and an empirical relationship for prediction of 28-days compressive strength derived from experimental results of the first mentioned end-product.

The AWARE team decided to split the control of the clinker kiln in a multi-layered control levels where various control objectives are evaluated, the high level control consisting of clinker microstructure analysis using shape and morphology descriptors.

By cooperation between project partners, using the technique developed in this project, industrial partner CARPAT will be able to optimise the clinker burning process and in this way expand the environmental and economic benefits alongside the growth of the company. The estimated economic benefits measures in energy savings that could vary between 2.5% and 10% or in reducing CO2 emissions for environmental benefits.

The Work Plan is structured to lead all participants in a period of 24 months to carry out their activities with the best profitable resources management so to achieve the common objectives. The methodology followed during the project will be to put in close collaboration the industrial participant with the research performers, in order to develop the two end-products of the project.
