Article
Full-text available
Driving the pseudocapacitive redox intercalation in 2DMXenes with neutral electrolytes is important for safer, more sustainable, and improved electrochemical charge storage. Single transition metal MXenes, such as Ti3C2, have shown great promise for energy storage, owing to their high conductivity and redox activity. Mixed metallic MXenes, such as...
Article
Full-text available
Device performance of solution‐processed 2D semiconductors in printed electronics has been limited so far by structural defects and high inter‐flake junction resistance. Covalently interconnected networks of transition metal dichalcogenides potentially represent an efficient strategy to overcome both limitations simultaneously. Yet, the charge tran...

Defect Engineering of Transition Metal Dichalcogenides The great variety of defects in solution‐processed transition metal dichalcogenides (TMDs) and their crucial influence on the physicochemical properties have recently prompted worldwide scientists to master their inherent features. In article number 2100122, Stefano Ippolito and Paolo Samorì re...
Article
Human health can be affected by materials indirectly through exposure to the environment or directly through close contact and uptake. With the ever‐growing use of 2D materials in many applications such as electronics, medical therapeutics, molecular sensing, and energy storage, it has become more pertinent to investigate their impact on the immune...
Article
Full-text available
Solution‐processed transition metal dichalcogenides (TMDs) are attracting unceasing attention owing to their wide‐ranging portfolio of physicochemical properties, making them prime candidates for low‐cost and real‐life applications in (opto)electronics, (bio)sensing, and energy‐related technologies. The performance of TMD‐based devices is strictly...
Thesis
Full-text available
This thesis work aims to develop new functionalization strategies based on defect engineering approaches for solution-processed transition metal dichalcogenides (TMDs). Their inherent structural defects, mainly sulfur vacancies (VS) located at the flake edges, behave as (re)active sites to form hybrid systems characterized by new properties and enh...
Article
Full-text available
Solution-processed semiconducting transition metal dichalcogenides are at the centre of an ever-increasing research effort in printed (opto)electronics. However, device performance is limited by structural defects resulting from the exfoliation process and poor inter-flake electronic connectivity. Here, we report a new molecular strategy to boost t...
Article

Here we show how temperature and reaction time are key towards efficient chemical exfoliation of MoS 2 into monolayer thick flakes with controlled content of metallic vs. semiconductive sheets.
Article
Full-text available
Graphene and other 2D materials, such as molybdenum disulfide, have been increasingly used in electronics, composites, and biomedicine. In particular, MoS2 and graphene hybrids have attracted a great interest for applications in the biomedical research, therefore stimulating a pertinent investigation on their safety in immune cells like macrophages...
Article
Dual functionalization of chemically exfoliated MoS2 has been achieved by exploiting Coulombic interactions among positively charged molecules and the negatively charged 2D flakes. The reversibility and kinetics of the process...
Article
Full-text available
Graphene is regarded as the ultimate material for future flexible, high‐performance, and wearable electronics. Herein, a novel, robust, all‐green, highly reliable (yield ≥ 99%), and upscalable technology is reported for wearable applications comprising reduced graphene oxide (rGO) as the electroactive component in liquid‐gated transistors (LGTs). r...
Article
The combination of 2D materials and photosensitive molecules enables the fabrication of high‐performance light‐responsive opto‐electronic devices whose physical and chemical properties can be efficiently and reversibly modulated between different states, paving the way towards the generation of multifunctional devices based on new smart integrated...
Article
During the last five years, the scientific community has witnessed a tremendous progress on solution-processed semiconducting 2D transition metal dichalcogenides (TMDs), in combination with the use of chemical approaches to finely tune their electrical, optical, mechanical and thermal properties. Because of strong structure-properties relationship,...
Article
The self-assembly behaviour of platinum (II) neutral complexes have been explored in derivatives exposing oligothiophene substituents in order to organize the semiconducting units in ordered supramolecular structures. The morphology and the photophysical properties of the assemblies were studied by scanning electron microscopy, powder X-ray diffrac...
Article
2D materials possess exceptional physical and chemical properties that render them appealing components for numerous potential applications in (opto)electronics, energy storage, sensing, and biomedicine. However, such unique properties are hardly tunable or modifiable. The functionalization of 2D crystals with molecules constitutes a powerful strat...
