High-performance graphene based nano-composites for anti-corrosion applications


Corrosion is a recurring issue causing serious damages to various infrastructures in chemical plants and public facilities . The cost of corrosion worldwide is estimated to around 2.2 trillion US dollars, which can also be pictured as 5 tons of steel disappearing each second in the world. In addition, the evolution of the cost of metals (Figure 1) compels firms to invest in corrosion protective measures to keep maintenance costs low. The oil and gas industry is particularly affected, due to the corrosive nature of the chemicals transported via pipelines. The depletion of easily-accessible fossil fuels pushes this industry to dig deeper into the sea bed, where oil is significantly more corrosive due to its higher sulphur content. As a result, pipes used for oil extraction suffer from a short service life.

Evolution of metal prices
Figure 1: Evolution of the prices of various metals used in anti-corrosion applications


Nanotechnologies are considered as a major driver towards the next industrial revolution. The recent breakthrough in graphene production appealed industrials to massively invest in new technologies that were previously deemed to costly. Graphene is known for its exceptional electrical conductivity and mechanical properties, but also for its permeability to chemicals (Figure 2). Solvay as world-leader in fluorinated polymers decided to invest in the development of fluorinated-graphene nanocomposites to satisfy a broad range of customers encountering various corrosion issues.

Graphene Honeycomb lattice
Figure 2: Graphene is an atomic-scale honeycomb lattice made of carbon atoms


The objectives were to reduce the permeability by at least a factor 2 compared to the matrix polymer (without graphene) while keeping similar mechanical properties. To reach these challenging objectives, three routes to graphene were explored for a given polymer matrix.

My Contributions

How it's made

Graphene nanocomposite process
Figure 3: Production process for graphene nanocomposites

Step 1

Suspension (A) consisted of a latex of fluorinated polymers manufactured in-house with good barrier properties compared to common polymers. To prevent a premature coagulation of suspension (A) surfactants are used. Suspension (B) consisted of a suspension of graphene sheets in water. In this project the water-based graphene suspension were produced via three distinct procedures

Step 2

Suspension (A) and Suspension (B) were added and mixed together to form a so-called suspension (AB) where the latex spheres covers the graphene sheets, the surfactant present in the latex prevent the coagulation of suspension (AB)

Step 3

Suspension (AB) was coagulated using acid or inorganic salts, the coagulum was separated from the water and thoroughly washed to remove any coagulating agent or surfactant remaining. The coagulum was the graphene nanocomposite powder

Step 4

The nanocomposite powder was then dried following a precise drying procedure and then placed in a mould to be compression moulded.

Elaboration of gold nanowires via dielectrophoresis for biosensor applications


Technology has undoubtedly changed every aspect of our lives, especially over the last two hundred years where people have been continuously tinkering, designing, and exploring in an attempt to unlock the mysteries and complexities of the human body. Over time, machines began to play a larger role in medicine, as innovators developed new and better ways to diagnose malfunction such as diabetes and epidemiological disease like swine flu. The lack of reliable and accurate devices to detect early diseases or harmful molecules in body fluids results in delays to administrate the right treatment to patients.


Nanotechnology is a very promising solution to produce a device capable of detecting, identifying, and quantifying biological substances in body fluids at very low concentration. Biologists, chemists and physicists, all together are keen to find solutions to make the life of suffering patients better and more comfortable. Nano-biosensors are one potential solution to this problem. The first step toward a bio-sensor is the growth of the nanowires: the backbone (Figure 1). Metallic nanowires can be obtained through diverse routes, like chemical vapour deposition, nanolithography and dielectrophoresis (DEP). Therefore, dielectrophoresis is one method that enables to grow nanowires in vivo. However, the reproducibility of the process is poor and requires further developments.

Gold nanowires grown via dielectrophoresis
Figure 1: Gold nanowires grown via dielectrophoresis


The main objective was to improve the reproducibility of the growth of gold nanowires via dielectrophoresis exploring the effect of the viscosity. Afterwards, the study has been extended to the electrical frequency and voltage, and the temperature of the medium.

My Contributions

How it's made

Production process of gold nanowires
Figure 2: Production process for gold nanowires

Step 1

A drop from a gold nanoparticles suspension (pink colour) was placed on the gold micro-electrodes. The gold particles were suspended in water and stabilised with tannic acid and a tri-ester potassium citrate giving a positive net charge to the gold particles (in yellow). The different process parameters were set. This includes the frequency, the peak-to-peak voltage, the temperature. The temperature was controlled with a Peltier element. Suspensions with different viscosity were tested.

Step 2

When the circuit is closed, a difference of potential between the two electrodes is created. In presence of an electric field the Au-NP is polarised and because its dielectric constant is lower than the one of water (medium), a positive net force oriented in the direction of the electric field is created. This force is called the dielectrophoretic force. Particles are aligned along the field lines and joined. The nanowire has started to grow.

Step 3

When the voltage alternate from positive to negative, the electric field orientation is switched over and so it the dielectrophoretic force. The wires grow on the other side of the electrode. Nanowires already grown are now part of the electrode and modify the field lines by creating a point of convergence where the field is more intense

Step 4

After multiple voltage inversions, nanowires were grown. After a certain time, a nanowire bridged the gap between the electrodes resulting in a short circuit and in sudden increase of the peak-to-peak voltage. At this point the trial was stopped.

Melt-spun and sintered Metal fibre networks for Lead-Acid Battery (MEMLAB)


The automotive industry is constantly making efforts to improve existing technology in order to manufacture more robust, more reliable and more energy-efficient cars. One major area of improvement is the reduction of the overall weight of the car (Figure 1), this would result saving energy, minimising brake and tyres wear, last but not least, lower CO2 emissions and improved fuel consumption. To put things into perspective, eliminating 2-3 kg from the 40 million automotive transmissions manufactured that same year would save up to 125 million litres of petrol or 1.7 million barrels of crude. Apart from the engine, transmission or carrosserie, weight can also be cut down in current lead acid batteries by substituting a part of the lead with lightweight materials, this is even more significant for electric vehicle where the weight of the batteries can reach more than 100kg.

Average weight per vehicle reduction projection for 2020
Figure 1: Average weight reduction per vehicle over the years and projection for 2020


The MEMLAB battery is targetted for the electric vehicle market where conventional lead-acid batteries are suitable due to their excessive weight and low energy-density. This major drawback can addressed by substituting heavy lead alloy, used for the die cast grid and plate battery electrodes, with alternative lightweight and porous electrode materials. The material developed in the project is based on state-of-the-art fibre production technology to create metal fibre networks (MFNs). The major challenges of the project lie in:

Gold nanowires grown via dielectrophoresis

The main project objectives are to achieve a 50% reduction in the battery weight and achieve 1000 charge-discharge cyles via the development of corrosion resistant and active lead coating.

My Contributions

How it's made

Production process of titanium metal fibre network
Figure 3: Production process for Titanium MFNs

Step 1

Scrap pure titanium (Gr. 1) was sourced from the aerospace or oil & gas industries as base material to manufacture the MEMLAB electrodes.

Step 2&3

The metal is melted with a plasma torch, and then a spinning and cooled profiled copper wheel is used to solidify and extract lengths of uniform metal fibres from the molten metal

Step 4

The fibres are randomly arrange to form a square (final dimension of the electrode). The fibres are placed in a vacuum furnace and run up at high temperature for few hours. The fibres are bonded via the sintering process.

Step 5

The sintered MFN then underwent successive treatment steps in order to deposit a lead layer that will provide the active material needed for the battery to work while protecting the titanium substrate. Two deposition processes were investigated electroplating and sol-gel. The electrodes are then assembled to form the MEMLAB lead acid battery

All glass mid temperature direct flow thermal solar vacuum tube (Soleglass)


Overall goals of Sustainable Energy Europe, the body appointed by European commission is to decrease the EU dependence on foreign energy sources and transform Europe into a low-carbon economy so to increase its energy security. The future landscape of European energy demands and supply will have to make much greater use of new renewable energy sources and focus more upon energy-efficient methods to achieve the European 20/20/20 goals. As heat accounts for 49% of the overall European Union final energy demand, the renewable heating sector will have to make a major contribution in order to reach the renewable energy target (Potential of Solar Thermal in Europe, ESTIF – European Solar Thermal Industry Federation). Compared with other forms of renewable energy, solar heating contribution in meeting global energy demand is, besides the traditional renewable energy like bio mass and hydropower, second only to wind power, and has a much larger contribution than photovoltaic.

Evolution of the installed solar capacity
Figure 1: Evolution of the installed capaciy of solar collector compared to expected reduction in cost of fabrication at horizon 2020


Thermal solar is a rapidly growing global market at all levels, indifferently whether it is related to the application field or temperature levels. The mid temperature range in Thermal Solar applications, from 100°C up to 300°C, is one with the highest market potential. Solar thermal heat generation in mid temperature range is combinable with a whole series of power generation, industrial and home applications as:

However, the implementation of the solar thermal technologies in the mid temperature application range today is limited, because of lack of reliable products and relatively expensive technologysolutions, primarily:

One of the major existing products limitation is complex vacuum retention technology for mid/high temperature range and subsequently the high product cost and also the glass-to-metal seal

Soleglass Bellow design drawing

The aim of the project is to construct a vacuum tube utilizing and combining the best features and advantages of both systems described previously, suitable for medium temperature range.

Taking in account all reasons mentioned in project objectives All Glass Tube will be developed in two variants:

Development and demonstration of compact, multi-source heat eXchanger technologies for Renewable energy applications (RenewX)


There are over 200 million households in Europe whose combined domestic heating needs account for around 30% of Europe’s energy demand. Reducing this will be essential if Europe is to achieve ambitious emission reduction targets (i.e. 2020 targets) and decrease our excessive reliance on imported energy. The clear solution to these two problems is to increase the amount of renewable energy used, an ambition at the heart of much recent EU legislation, of which new Heat Pump systems are a key enabling technology


Despite the recent success of the European heat pump industry there are still several major challenges to overcome and opportunities that need to be exploited. (Figure 1). Despite significant incremental technological progress (i.e. compressor technology, refrigerants, valves), heat pumps still command a price premium compared to modern condensing boilers. If no subsidies are available, this means that a heat pump (when competing directly with gas) must significantly outperform gas based alternatives, which is difficult as the gas price typically ranges at 1/3 of the price of electricity per kWh. Furthermore, compared to ground source heat pumps, little changes have been made to the conventional finned tube heat exchangers used in air source heat pumps. The latter have much wider applicability on a European scale. The main project objectives are as follows:

Heat pump market data

RenewX project aims at developing and demonstrating a novel and competitive heat exchanger technology platform enabling the integration of secondary or tertiary energy sources and manufacturing processes that will enable increased market penetration of European-made heat pump systems.

Development of a force field to compute the ab-initio energy of amino-acids


The rise of computers in 1950 and the exponential growth of computer processing power (Moore's law - Figure 1.) have unlock new possibilities for scientist to run the most complex and time consuming mathematical algorithms to predict and understand complex and sophisticated chemical processes. The progress of technology has open a new door to a new type of science, computational quantum chemistry where the prediction of phenomenon become possible


Computer predictions offer an opportunity to biologists and chemists to comprehend the reactivity of large and multifunctional molecules such as protein-ligand interactions in the human body with the objective to develop new drugs. The development of mathematical models to predict the activity of drugs on certain proteins offers insight where laboratory experiment is ambiguous, impossible, hazardous, time-consuming or just too costly.

Turbo Annonces - Automation software to list classified ads


As a student, I used to undertake occasional jobs to make some pocket money, such as private tuitions or providing outcall computer troubleshooting services. My services were mostly promoted through a classified ad website called Leboncoin. One day, I received a request from an online shop owner who needed help with listing thousands of products on the Leboncoin platform. Unfortunately, at that time, there was no API available to automate the process or upload the listings in bulk. Therefore, the only option was to manually transfer the details and images of each listing from the online shop's website to the Leboncoin platform, which could take around 2-3 minutes per ad. Automating the process seemed like the most logical solution.


It was evident that the current process of manual listing creation was not only time-consuming but also prone to errors, making it an inefficient method. In light of this, it became imperative to develop a software solution to speed up the task. The original gig involved publishing 1300 listings at a rate of 0.25 euros per listing, which would take approximately 65 hours to complete manually. Hence, it made practical sense to create a prototype software that could automate the process, thereby reducing the time and effort required. Additionally, the developed software could be marketed to other online shop owners seeking to enhance productivity and visibility while minimizing costs associated with manual labour.

The Software

The initial application mainly focused on automatically posting listings to the Leboncoin website. As development shifted to commercialisation, the application became a suite of applications with 4 distinct applets

General user interface of the poster
Screenshot 2: The Poster's general user interface

Key developments

General user interface of the Ebay lister
Screenshot 3: Ebay Lister's general user interface


The initial setback that the suite encountered was the alteration in the Leboncoin platform's policy. Initially, the platform had no limitations on the number of listings per account. However, this changed later on, and individual accounts were limited to 5-10 listings, while professional accounts could list more items but were required to pay a fixed fee based on the item type (ranging from 3-8 euros). This resulted in a significant reduction in the suite's total addressable market and value-for-money in general. Furthermore, Leboncoin enhanced its approval process, resulting in a significant number of listings being rejected. To mitigate bot activity, they also introduced a captcha feature.

Initially, the approach was to discontinue support for the Leboncoin platform and instead focus on expanding support for eBay Stores. I initiated this strategy, but after six months of intensive work, I realized that catching up with the competition would require significant resources, and I was unable to dedicate the necessary time to this project at that time. As a result, in 2014, I decided to relinquish my self-employed status and can the project.

Citylife Nottingham Ltd. - Events and Trips for international students


During my first year in Nottingham, UK, I was eager to socialise and make new friends. To this end, I attended a Bar crawl event, where I met Seb and Simon, who were organising the event. It was one of their first events, and after discussing for a while, I proposed that we join forces since I had prior experience running events, mainly during my time in Cambridge. Initially, my role was to act as a representative, selling bar crawl tickets, as the business expanded to include additional events like Meet&Speak's and trips. In January 2016, Citylife Nottingham Ltd. was officially established, and by June 2016, I became one of the acting CEOs. At its peak, Citylife Nottingham was running four weekly events and international trips such as an 8-day long Morocco trip and a Euro Trip.


The opportunity was clear, competition was quasi-inexistent for international student events in a city with more 110k students (15k were non-UK). Our direct competitor 'Viva la fiesta' was running for a number of years but had low customer satisfaction due to poor execution. The business quickly gained market share forcing Viva la fiesta to fold in Nottingham. Citylife Nottingham expanded to Leeds and Manchester in the following years

As an acting co-CEO, I had the opportunity to overview the broad business operations from preparing trips, to launching events and developing technical tools to run our marketing strategy

The main issue with this type of business was scale. There were very little opportunities for economies of scale. The second issue was the over reliance on Facebook for advertising and the fact that most international students only stay 1 or max 2 semesters. This meant that marketing efforts had to constantly be renewed with no options to capitalise on previous effort.

In June 2018, I decided to step down from my position of co-CEO as I ambitioned to focus on something different and more scalable. In 2020, the Covid-19 pandemic happened and Citylife had to pause all its operations. To this date, it is unclear if Citylife UK will resume its operations.
