Environmental pollutants carried by water and air are one of the most important problems that destroy resources today. Herein, a proof-of-concept of a new colorimetric-fluorescent environmental-medical sensor is demonstrated by testing two hypotheses: (1) by combining artificial receptors with microfluidics, sensors based on color changes for acrolein and formaldehyde molecules can be developed, and (2) using microfluidics designed with carbon...

The wastewater containing Methylene Blue (MB), released by textile factories after dying Jean clothes, is significant pollution in the environment. We propose a photocatalytic protocol for MB treatment, as semiconductor photocatalysis uses sunlight to decompose organic pollutants (MB). We have used, for this, CZTS nanoparticles synthesized by the solvothermal method. The protocol shows that about 88% of MB was decreased...

We used hydrolyzed lignin extracted from the hard shell of chestnuts. We then combined lignin with polyvinyl alcohol(PVA) and utilized electrospinning to polymerize the solution and create a nanofiber matrix. Testing the matrix showed that the matrix could be used to create a recyclable, biodegradable facial mask. Observations under SEM allowed us to observe the nanostructure of the matrix, and...

Electroosmosis is the motion of an electrically neutral fluid under the influence of an electric field due to interface breaking of local electrical neutrality. We analyzed a simple system in which there are non-linear effects present, related to the bulk electrolyte depletion caused by the accumulation of ions at the electrodes. The apparent electroosmotic velocity was measured and the zeta...

Our group’s motto in abbreviated form is (CEP) which we interpret as contamination, experimentation and purification. After discovering a gigantic environmental problem, which is water CONTAMINATION by polycyclic aromatic hydrocarbons and nanoplastics, we decided to take the initiative and started our own EXPERIMENTS which enabled us to develop the nanoparticles (NPs) which have the ability to PURIFY water. Our aim...

Geopolymer concretes are a sustainable alternative to traditional concrete, characterised by their use of lower amounts of energy and raw materials, whilst having durable chemical and physical properties. Geopolymer concretes are produced through a geopolymerisation reaction, made by activating source materials such as fly ash with alkaline solutions. The investigation’s aim was to compare the durability of fly ash based...

To maximise the efficiency of antibiotics, working against the proliferation of harmful bacteria, the chemical "clavulanic acid" has been introduced to the medical industry working alongside penicillin branches to prevent bacterial resistance. But, after research, it is evident that its impacts are detrimental to bacteria that present a mutualistic relationship with the human body,such as the ones in the gut...

Our project aims to find new strategies for identifying chemical residues that are toxic to the environment and humans using Green Chemistry principles and Nanotechnologies. The Italian production of rice is about 1,500,000 tons/year, despite these numbers large quantities of rice are imported to meet national needs. We developed a colorimetric sensor based on gold nanoparticles for the detection of...

Gene therapy is a promising approach to the treatment of hereditary and acquired diseases, which consists in the introduction of therapeutic nucleic acids into the cell for a targeted change in its functions. Cationic liposomes are able to protect such nucleic acids from biological factors, and to deliver them into target cells. An important component of cationic liposomes are helper...
