Projects and Events

Since the beginning, nChemi has used the expertise of its team to develop research projects on new technologies through the support of development agencies and innovation programs of large companies. We are always in touch with new market demands and using the potential of nanotechnology to create innovative solutions.


The development of functionalized nanoparticles (NPF) provides a wide range of applications in various areas of engineering materials such as energy example, medical, electronic, structural and mining. Such applications generally are in the scientific development threshold and therefore, have great potential to become disruptive technologies, attracting investors, moving the economy and generating new business opportunities. However, the industrial scale production of these materials also presents a technological and commercial barrier to its use is widespread in fact and leave the lab bench. Given this scenario, the first to overcome such barriers will be leading a high financial and strategic value market. The processes of NPFs synthesis of Fe3O4, TiO2 ZrO2 and developed in the first phase of this project have high reproducibility, scheduling, competitive cost while maintaining the quality and properties of the synthesis on a smaller scale. These characteristics are essential for these materials become commercial products of high technology and disruptive potential on national and international scale. For this potential to be achieved, are still necessary improvements and validation of methods of synthesis, post-synthesis processing, waste treatment, minimizing costs, in addition the insertion the market through partnership with companies and institutions that seek high-tech solutions may be customers. All these factors are objectives of Phase 2 project, and at the end of 2 years obtain the final commercial product, ie bottles containing different compositions of NPFs in different concentration and volume and according to customer demand. For the processes involved in the synthesis, from its conception to the final packaging, characterization and comparative analysis with an ideal standard certified by the company will be made, according to the yield, cost, waste volume and sample characteristics. Insertion on market will be carried out by mapping potential customers and sending samples for the product to be tested and if necessary be modified to meet customer demand. For each NPF a specific market will be seeked, according to their application possibilities, as follows: Fe3O4 – adhesives, polymers and medicine TiO2 – cosmetics, photovoltaic devices, thin films ZrO2 – thin films, metal protection (corrosion and wear), gas barrier The nChemi Materials Engineering Ltd., “startup” created in Phase 1 of this project, and has initiated the first steps towards a partnership with two other companies that may be customers of its technologies. The company also has the technical and structural support of the Interdisciplinary Laboratory of Electrochemistry and Ceramics at the Federal University of São Carlos (LIEC-UFSCAR) and Functional Materials Development Center (CEPID 2013 / 07296-2) which the laboratory is a key member. This support has been shown essential in the first phase of the project and is of fundamental importance in the development of phase 2.

The use of nanomaterials for the development of flexible electronic devices, especially in organic photovoltaics (CFOs), has been successfully carried out both by academia and by printed and organic electronics industry. In this context, transition metal oxides nanocrystals (CN) are used in the doping of the hole transporting interlayer, PEDOT: PSS or its complete replacement for thin films produced from tungsten oxide inks (WOX). Such modification is performed when it is willing to increase the lifetime of the device as well as the solar energy conversion efficiency into electric energy. Thus, this project focuses on the continuity of the development proposed in the PIPE Phase 1 and on the technological challenges encountered during this phase. Surface and structural changes in the NC, as well as the elimination of contaminants will be the main challenges to overcome in the Phase 2, since the product has promising performance in the production of CFOs, confirmed by our partner/customer (CSEM Brazil). Indeed, once overcoming these challenges, the product will become highly competitive either in sales price or performance. In this way, NCs are produced via the nonaqueous solvotermal method in organic médium because is a versatile method that allows the nanomaterials sythesis with high process control. So, at the end of this Project, it is expected to obtain an ink that can be applied effectively in the production of CFOs, establish two more industrial partnerships and explore other technologies application for the tungsten oxide nanostructured ink.

The biomedical field demands quick and simple diagnosis along with effective and non-invasive methods. Development of building blocks with specific functions can be the answer to this demand; magnetic nanoparticles (MNPs) have became a promising technology because of its low toxicity and unique magnetic properties. A peculiar class of nanomaterials that can demonstrate an outstanding performance are the so called functionalized nanoparticles. These are particles that present organic molecules bonded onto its surface, i.e., an organic layer. Hence, the MNPs have provided the optimization of regular techniques or the development of totally new ones, such as bioconjugation, magnetic hyperthermia, magnetic resonance imaging and target drug delivery. For these applications, the MNPs requirements include controlled size, high dispersivity and compatibility in biological environment. This specificity is achieved by controlling the synthesis parameters and the organic components used. In the Phase 1 of the project, a new synthesis of amine-terminated magnetic nanoparticles for the immobilization of biocomposites was obtained, it is an easy-to-obtain synthesis using non-polluting reagents and fully reproducible solvents. The magnetic nanoparticles that emerged from this synthesis were called Magnus Bio. Magnus Bio was characterized as having a superparamagnetic nanoparticle with a diameter of 5 – 10 nm. The activity of the surface amine groups was observed from the immobilization with the enzyme acetylcholinesterase forming bioreactors, the bioreactors were reacted with acetylcholine and the product of that reaction, choline, was monitored by LC-MS. It was found that the amine endings of Magnus Bio were not only active, but a 50% lower mass concentration of Magnus Bio provided better results than the standard commercial particles used for the formation of the bioreactors.

Innovation Fair – Dow Química

This was the first event in which nChemi registered as a company, and also the first in which it was selected. The event aimed to bring together companies and research groups that had innovative ideas for solving the challenges proposed by Dow Química Brasil. Our proposal was to use nanoparticles functionalized in adhesives and foams to modify their properties and it was presented to investors, technical and executive employees of the company. The presentation gave us nChemi’s first non-disclosure agreement and for approximately one year, we interacted with Dow researchers in the development of the project.

Nano Trade Show

First fair where nChemi was present as a stand, a new experience for the team. In addition to companies that developed or marketed products with nanotechnology, there were also research groups publicizing research in the area. At the event there was also a pitching session for investors and nChemi, the only “hard science” company to participate, was selected as one of the best and received an award from IBM.

Leaders in Innovation Fellowships

The Leaders in Innovation Fellowships (LIF) programme brings together emerging leaders who have an engineering based innovation that has the potential to contribute to the social and economic development of their country through commercialization. Bruno Lima and Tiago Conti, both founders of nChemi, participated in the LIF program in 2016 in London, presenting solutions based on nanotechnology. The program contributed to the personal growth of the participants and also of the company through contact with other companies from different countries and workshops on innovation, business management and marketing.

MRS iMatSci

The Materials Research Society meetings are the largest and most important events in the field of materials research and bring together researchers from all over the world to present papers and discuss the direction that materials science is taking. The nChemi team had already participated in these events on other occasions as researchers, however in 2017 it was the first time that they participated as a company in iMatSci, an event that was part of the MRS Fall Meeting – Boston program. Startups from all over the world signed up and nChemi was among the 17 selected to present their technology to researchers, professionals and investors. The technology that we brought to the event was Colossus Spray, which at the time would be a way to deposit nanometric ceramic coatings on metal parts through aerosol. This technology has evolved and today is the basis of Plenus Med, our coating for surgical instruments.

Mining Lab – Nexa Resources

nChemi was one of the companies selected in the first edition of the Mining Lab, in 2017. That year the event was looking for startups and entrepreneurs in the field of energy and nanotechnology. The event had a period of 15 days of training and interaction with members of Votorantim Metais (currently Nexa Resources) in the city of Belo Horizonte and also a final presentation in the same period. Our proposal was the development of a technology for removing metal ions from mining waste water and reusing these ions, and with it we were the final company in the program in the area of ​​nanotechnology. After the event, a project development contract was signed with Votorantim and we were able to validate the technology on a laboratory scale.

Emerge Labs – BRF

nChemi was one of the companies selected to participate in the Emerge program with the BRF group for the development of technologies to combat food waste. During the program, members of the nChemi team participated in face-to-face workshops and visits to BRF facilities. In this program, nChemi proposed the use of nanoparticles in packaging to increase the shelf life of food.
