3D printing of fully cellulose-based hydrogels by digital light processing

We report on the development of natural-based, composite hydrogel inks for Digital Light Processing (DLP) 3D printing, composed entirely of cellulose-based-materials. DLP, which enables the production of complex con- structs by photopolymerization, is already considered an environmentally friendly production method but it is still based on fossil chemicals, which may be a limit in the future. On the contrary, in view of a more environmental-friendly production, the development of natural ...

Strong correlation and ferromagnetism in (Ga,Mn)As and (Ga,Mn)N

The band energies of the ferromagnetic diluted magnetic semiconductors (Ga,Mn)As and (Ga,Mn)N are calculated using a self-interaction-free approach which describes covalent and strongly correlated electrons without adjustable parameters. Both materials are half-metallic, although the contribution of Mn-derived d states to the bands around the Fermi energy is very different in the two cases. In (Ga,Mn)As the bands are strongly p-d hybridized, with a dominance of As p states. In contrast in (Ga...

Angular Analysis of D0→π+π−μ+μ− and D0→K+K−μ+μ− Decays and Search for CP Violation

The first full angular analysis and an updated measurement of the decay-rate CP asymmetry of the D0 → πþπ−μþμ− and D0 → KþK−μþμ− decays are reported. The analysis uses proton-proton collision data collected with the LHCb detector at center-of-mass energies of 7, 8, and 13 TeV. The dataset corresponds to an integrated luminosity of 9 fb−1. The full set of CP -averaged angular observables and their CP asymmetries are measured as a function of the dimuon invariant mass. The results are consisten...
