Decorative Chromium Coatings on Polycarbonate Substrate for the Automotive Indu...
Ponte, Filipa; Sharma, Pooja; Figueiredo, Nuno Miguel; Ferreira, Jorge; Carvalho, SandraMetal-coated plastic parts are replacing traditional metallic materials in the automotive industry. Sputtering is an alternative technology that is more environmentally friendly than electrolytic coatings. Most metalized plastic parts are coated with a thin metal layer (~100-200 nm). In this work, the challenge is to achieve thicker films without cracking or without other defects, such as pinholes or pores. Chr...
Antimicrobial Polymeric Surfaces Using Embedded Silver Nanoparticles
Sharma, Pooja; Fialho, Luisa; Figueiredo, Nuno Miguel; Serra, Ricardo; Cavaleiro, Albano; Carvalho, SandraPathogens (disease-causing microorganisms) can survive up to a few days on surfaces and can propagate through surfaces in high percentages, and thus, these surfaces turn into a primary source of pathogen transmission. To prevent and mitigate pathogen transmission, antimicrobial surfaces seem to be a promising option that can be prepared by using resilient, mass-produced polymers with partly embedded antimicrobi...
Investigating the Synergistic Effect of Electrochemical Texturing and MoSeC Coa...
Mahadeshwara, Manoj Rajankunte; Rosa, Fátima Margarida dos Santos; Vuchkov, Todor; Vilhena, Luis M.; Ramalho, Amílcar; Sharma, Pooja; Cavaleiro, AlbanoThe materials used for the piston cylinders of automobile engines, or the ring and tappets of various mechanical components, are continuously experiencing lubricated sliding motions. These surfaces are prone to damage due to the various tribological aspects of friction and wear. Hence, enhancing their surface properties would contribute to increasing their life and saving energy and resources. For many decades ...

Organic waste recycling for carbon smart circular bioeconomy and sustainable de...
Awasthi, Mukesh Kumar; Yan, Binghua; Sar, Taner; Gómez-García, Ricardo; Ren, Liheng; Sharma, Pooja; Binod, Parameswaran; Sindhu, RaveendranThe development of sustainable and low carbon impact processes for a suitable management of waste and by-products coming from different factors of the industrial value chain like agricultural, forestry and food processing industries. Implementing this will helps to avoid the negative environmental impact and global warming. The application of the circular bioeconomy (CB) and the circular economic models have be...
Synthesis, Characterization and Irradiation of Fullerene Based Metal Nanocompos...
Sharma, PoojaDocumentos apresentados no âmbito do reconhecimento de graus e diplomas estrangeiros; The present research work entitled “Synthesis, Characterization and Irradiation of Fullerene Based Metal Nanocomposites” envisages the study on the feasibility of using fullerenes, one of the most emerging functional materials as a matrix for the reinforcement of metal nanoparticles. Fullerene matrix nanoparticles embedded com...
