Intensity-Modulated Photocurrent Spectroscopy and Its Application to Perovskite Solar Cells
(American Chemical Society, 2020-09-23)
Frequency domain techniques are useful tools to characterize processes occurring on different time scales in solar cells and solar fuel devices. Intensity-modulated photocurrent spectroscopy (IMPS) is one such technique ...
Surface-Functionalized Polystyrene Nanoparticles Alter the Transmembrane Potential via Ion-Selective Pores Maintaining Global Bilayer Integrity
(ACS Publications, 2022)
Although nanoplastics have well-known toxic effects toward the environment and living organisms, their molecular
toxicity mechanisms, including the nature of nanoparticle−cell membrane interactions, are still under ...
All-optical coherent pulse compression for dynamic laser ranging using an acousto-optic dual comb
(Optical Society of America, 2021-07-22)
We demonstrate a new and simple dynamic laser ranging platform based on analog all-optical coherent pulse compression of modulated optical waveforms. The technique employs a bidirectional acousto-optic frequency shifting ...
Light intensity modulated impedance spectroscopy (LIMIS) in all-solid-state solar cells at open-circuit
(Elsevier, 2020)
Potentiostatic impedance spectroscopy (IS) is a well-established characterization technique for elucidating the electric resistivity and capacitive features of materials and devices. For solar cells, by applying a small ...
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 ...
High proton conductivity at low and moderate temperature in a simple family of Prussian blue analogs, divalent transition metal hexacyanocobaltates (III)
(Elsevier, 2020-11-10)
Proton conductivity behavior was studied in a family of hexacyanocobaltates with divalent transition metals (II), HCCMs. The HCCMs, with molecular formula M3[Co(CN)6]2∙xH2O (where M = Ni, Co, Fe, Mn and Cd), had cubic ...
Electrical conductivity of an all-natural and biocompatible semi-interpenetrating polymer network containing a deep eutectic solvent
(Royal Society of Chemistry, 2020-07-29)
A series of semi-interpenetrating polymer networks (semi-IPNs) consisting of crosslinked poly(itaconic
acid) in the presence of the polysaccharide inulin were prepared by free-radical polymerization, taking
advantage of ...
Understanding the Improvement in the Stability of a Self-Assembled Multiple-Quantum Well Perovskite Light-Emitting Diode
(American Chemical Society, 2020-11-07)
We fabricate two-dimensional Ruddlesden–Popper layered perovskite films by introducing 1-naphthylmethylamine iodide into the precursor, which forms a self-assembled multiple-quantum well (MQW) structure. Enabling outstanding ...
