Switching From Acceptor to FRET Donor: How the Organic Solar Cell Architecture Can Change the Role of a Chromophore

open access: yesAdvanced Functional Materials, EarlyView.
The non‐fullerene acceptor o‐IDT‐BT‐DCV is used in both binary and ternary blends to investigate the role that it plays in each device architecture. The charge generation pathways are found to differ between the binary and ternary blends with o‐IDT‐BT‐DCV becoming a second donor in the ternary blend.

Frozen capillary waves on glass surfaces: an AFM study

open access: yes, 2006
Using atomic force microscopy on silica and float glass surfaces, we give evidence that the roughness of melted glass surfaces can be quantitatively accounted for by frozen capillary waves.

Structural and optical properties of BaTiO3 thin films prepared by pulsed laser deposition

open access: yesIraqi Journal of Physics, 2012
BaTiO3 thin films have been deposited on Si (111) and glass substrates by using pulsed laser deposition technique. The films were characterized by using X-ray diffraction, atomic force microscope and optical transmission spectra.

Relation Between the Defect Interactions and the Serration Dynamics in a Zr-Based Bulk Metallic Glass

open access: yesApplied Sciences, 2020
For this study, the effects of thermal annealing and compressive strain rate on the complexity of the serration behavior in a Zr-based bulk metallic glass (BMG) was investigated.

Quantum wavefunction annealing of spin glasses on ladders [PDF]

open access: yesJournal of Statistical Mechanics: Theory and Experiment, 2007
A technique inspired on quantum annealing is proposed in order to obtain the classical ground state of a spin-glass by tracking the full wavefunction of a given system within the subspace of matrix product states (MPS), using the density matrix renormalization group (DMRG).

Toward Architected Microstructures Using Advanced Laser Beam Shaping in Laser Powder Bed Fusion of Ti‐6Al‐4V

open access: yesAdvanced Functional Materials, EarlyView.
This research applies advanced laser beam shaping (LCoS‐SLM) to fabricate the Ti‐6Al‐4V alloy via laser powder bed fusion. A tailored beam is used to prevent martensite formation and create a dual α+β microstructure by controlling cooling rates.

Practical remarks on annealing flint-glass [PDF]

open access: yesAbstracts of the Papers Communicated to the Royal Society of London
This paper is entirely occupied with practical details relating to the art of annealing flint-glass and depriving it of colour, the author stating that he leaves the rationale of these facts to be explained by philosophers. He thinks, however, that they are reconcileable with the theory of Scheele, as explained by Bergman, and detailed by Murray in his

Superlubricious Surfaces Through Surface Attached Hydrogels Obtained by C,H‐insertion Crosslinking

open access: yesAdvanced Functional Materials, EarlyView.
Taking synovial joints as a source of inspiration, the friction properties of surfaces covered with 1d‐swelling polyelectrolyte hydrogels in combination with a shear‐thinning aqueous lubricant are studied. Such systems obtained by C,H insertion crosslinking show superlubricious behavior, even surpassing the friction values reported for the natural ...

Polymer Brush Growth by Surface‐Initiated Ring‐Opening Polymerization from a Cross‐Linked Polymer Thin Film

open access: yesAdvanced Functional Materials, EarlyView.
A stable cross‐linked ultra‐thin polymer coating for surface‐initiated ring‐opening polymerization (SI‐ROP) of hexamethylcyclotrisiloxane and ε‐caprolactone for growth of high grafting density poly(dimethyl siloxane) and poly(caprolactone) brushes is developed.

Structural changes in chemically deposited CdS: effect of thermal annealing

open access: yesMoldavian Journal of the Physical Sciences, 2010
The dynamics of changes in the structural and optical properties of chemical bath- deposited (CBD) CdS/glass thin films in H2 annealing process in a pre-heated furnace between 200–450°C was studied systematically. Annealing imparts structural stability
