Tunable light emission by exciplex state formation between hybrid halide perovskite and core/shell quantum dots: Implications in advanced LEDs and photovoltaics
(American Association for the Advancement of Science, 2016)
We report the first observation of exciplex state electroluminescence due to carrier injection between the hybrid lead halide perovskite (MAPbI3–xClx) and quantum dots (core/shell PbS/CdS). Single layers of perovskite (PS) ...
Decoupling manufacturing from application in additive manufactured antimicrobial materials
(Royal Society of Chemistry, 2021-05-11)
3D printable materials based on polymeric ionic liquids (PILs)
capable of controlling the synthesis and stabilisation of silver
nanoparticles (AgNPs) and their synergistic antimicrobial activity
are reported. The ...
Balanced change in crystal unit cell volume and strain leads to stable halide perovskite with high guanidinium content
(Royal Society of Chemistry, 2022)
Up-to-date studies propose that strain in halide perovskites is one of the key factors that determine
a device's efficiency and stability. Here, we show a systematic approach to characterize the
phenomenon in the standard ...
Ag Nanoparticles/α-Ag2WO4 Composite Formed by Electron Beam and Femtosecond Irradiation as Potent Antifungal and Antitumor Agents
(Nature ResearchNature Research (part of Springer Nature), 2019)
The ability to manipulate the structure and function of promising systems via external stimuli is emerging with the development of reconfigurable and programmable multifunctional materials. Increasing antifungal and antitumor ...
Mechanism of carrier accumulation in perovskite thin-absorber solar cells
(Nature Publishing Group, 2013)
Photovoltaic conversion requires two successive steps: accumulation of a photogenerated charge and charge separation. Determination of how and where charge accumulation is attained and how this accumulation can be identified ...
Hydrophobic Pulmonary Surfactant Proteins SP-B and SP-C Induce Pore Formation in Planar Lipid Membranes: Evidence for Proteolipid Pores
(Biophysical Society, 2013-01-08)
Pulmonary surfactant is a complex mixture of lipids and specific surfactant proteins, including the hydrophobic proteins SP-B and SP-C, in charge of stabilizing the respiratory surface of mammalian lungs. The combined ...
Selective contacts drive charge extraction in quantum dot solids via asymmetry in carrier transfer kinetics
(Nature Publishing Group, 2013)
Colloidal quantum dot solar cells achieve spectrally selective optical absorption in a thin layer of solution-processed, size-effect tuned, nanoparticles. The best devices built to date have relied heavily on drift-based ...
Electrical pumping of potassium ions against an external concentration gradient in a biological ion channel
(AIP Publishing, 2013-07-22)
We show experimentally and theoretically that significant currents can be obtained with a biological ion channel, the OmpF porin of Escherichia coli, using zero-average potentials as driving forces. The channel rectifying ...
Interplay Between Fullerene Surface Coverage and Contact Selectivity of Cathode Interfaces in Organic Solar Cells
(ACS Publications, 2013-04)
Interfaces play a determining role in establishing the degree of carrier selectivity at outer contacts in organic solar cells. Considering that the bulk heterojunction consists of a blend of electron donor and acceptor ...
Ion transport through biological channels
(Institut d’Estudis Catalans, 2015)
The transport of ions across single-molecule protein nanochannels is
important both in the biological context and in proposed nanotechnological applications.
Here we discuss these systems from the perspective of ...
