A quantum dot is a nanometric crystalline structure of semiconductor materials. In a quatum dot electrons are confined in a region of space, thus creating a well defined structure of energy levels that depends very much on the size and shape of the quantum dot. This structure resembles that of atoms, that is why sometimes…
Exfoliated semiconducting MoS2 and WS2 were covalently functionalized with 1,2-dithiolane-modified carbon nanodots (CNDs). Based on electronic absorption and fluorescence emission spectroscopy, modulation of the optoelectronic properties of transition metal dichalcogenides (TMDs) by interfacing with CNDs was accomplished.
Last week the conference NanoteC18 was held at Sussex University in Brighton, UK, where it was first held in 1998. This year’s edition was celebrating the 20th anniversary of the conference and was also dedicated to the late Prof Sir Harry Kroto NL, who received the Nobel prize for discovery of the carbon football molecule,…
Ammonium modified MoS2 and WS2 were prepared and characterized by complementary spectroscopic, thermal and microscopic means. The positive charges on functionalized MoS2 and WS2, owed to the presence of ammonium units, were exploited to electrostatically bring in contact an anionic porphyrin bearing a carboxylate moiety, yielding porphyrin/MoS2 and porphyrin/WS2 nanoensembles, respectively.
Los polímeros conjugados constituyen la base de los dispositivos optoelectrónicos en forma de películas finas, como son las celdas solares orgánicas y los dispositivos de emisión de luz orgánicos. Depositados sobre grandes áreas contribuyen al desarrollo de plataformas de comunicación inteligentes, autónomas y ubicuas. Pero su fabricación requiere disolventes orgánicos, la mayoría tóxicos y su…
Recent advances in large-scale production of graphene have led to the availability of solution-processable platelets at the commercial scale. Langmuir-Schaefer (L-S) deposition is a scalable process for forming a percolating film of graphene platelets which can be used for electronic gas sensing. Here, we demonstrate the use of this deposition method to produce functional gas…
Emin Istif, Javier Hernandez-Ferrer, Esteban P. Urriolabeitia, Anastasios Stergiou, Nikos Tagmatarchis, Giuseppe Fratta, Matthew J. Large, Alan B. Dalton, Ana M. Benito, Wolfgang K. Maser Advanced Functional Materials, 2018, 1707548 The game‐changing role of graphene oxide (GO) in tuning the excitonic behavior of conjugated polymer nanoparticles is described for the first time. This is demonstrated by using poly(3‐hexylthiophene) (P3HT) as…
The preparation, characterization and photophysical and electrocatalytic properties of carbon nanodots (CNDs)/MoS2 ensembles were reported. Based on electrostatic interactions, ammonium functionalized MoS2, prepared upon reaction of 1,2-dithiolane tert-butyl carbamate with MoS2 followed by acidic deprotection, was coupled with CNDs bearing multiple carboxylates on their periphery as derived upon microwave-assisted polycondensation of citric acid and ethylenediamine…
Launch of Newco to exploit supercapacitor technology Sebastian Nufer, PhD student at M-Solv Ltd, supported by Richard Lee of Academatch. A business model canvas was employed to provide a broad outline of the opportunity and the key steps and work streams required to bring the business to market. Key components included, business partners, value proposition,…
Expociencia. Parc cientific, Valencia (Spain ) On the 26th of May, the Expociencia 2018 project will be held in Valencia, Spain. This project, which is coordinated by the ‘Parc cientific’ (CSIC) and the University of Valencia, tries to disseminate science to the general public. The main objective of the project is to showcase the importance…

“Enabling Excellence” ITN has organised a two day workshop for users of the AIMPRO code in Exeter, UK, from 26th to 27th March 2018, in conjunction with Strathclyde University. The AIMPRO code uses density functional theory methods to solve the quantum mechanics that controls the distribution of nuclei and electrons in materials.
London 12-13 March 2018 A goal of the ITN is to improve the ability of the PhD students to communicate their research to the public and to business sectors. Manuela Meloni, PhD student at the University of Sussex, participated in the Materials Research Exchange & Investor Showcase (MRE2018) in London. She showed her recent…
In celebration of the International Day of Women and Girls in Science, Ana Santidrián García, PhD student at Instituto de Carboquímica ICB-CSIC in Zaragoza, have collaborated in the exhibition “Women in Science” which is locating in the library La Pantera Rossa (San Vicente de Paúl, 28, 50001 Zaragoza).
As part of the Enabling Excellence project the students have an exercise in communication about nanoscience. It is called the Grand Challenge. Three PhD students: Ana SANTIDRIAN GARCIA, Lorenzo VALLAN and Emin ISTIF chose to communicate nanotechnology and nanoscience to children and high school students.
