Synaptical Tunability of Multipore Nanofluidic Memristors
(American Chemical Society (ACS), 2023-11-27)
We demonstrate a multipore nanofluidic memristor with conical pores showcasing a wide range
of hysteresis and memristor properties that provide functionalities for brain-like computation
in neuromorphic applications. ...
Molecular Basis of RNA-Driven ATP Hydrolysis in DExH-Box Helicases
(American Chemical Society, 2023-03-29)
The spliceosome machinery catalyzes precursor messenger (pre-m)RNA splicing. In each cycle, the spliceosome experiences massive compositional and conformational remodeling fueled by the concerted action of specific ...
Suppressing Nonradiative Recombination in Lead–Tin Perovskite Solar Cells through Bulk and Surface Passivation to Reduce Open Circuit Voltage Losses
(American Chemical Society, 2022-10-14)
Lead–Tin perovskite solar cells (Pb/Sn PSCs) are limited by the intrinsic instability of Sn(II), which tends to oxidize forming Sn vacancies in perovskite films. Herein, a Lewis base β-guanidinopropionic acid (GUA) and ...
Inductive and capacitive hysteresis of current-voltage curves: unified structural dynamics in solar energy devices, memristors, ionic transistors, and bioelectronics
(American Physical Society, 2024-01-08)
Hysteresis observed in the current-voltage curves of both electronic and ionic devices is a phenomenon where the curve's shape is altered on the basis of the measurement speed. This effect is driven by internal processes ...
Enhancing the Electronic Properties and Stability of High-EfficiencyTin-Lead Mixed Halide Perovskite Solar Cells via DopingEngineering
(American Chemical Society, 2022-03-31)
Overcoming Voc loss to increase the efficiency of perovskite solar cells (PSCs) has been aggressively studied. In this work, we introduce and compare rubidium iodide (RbI) and potassium iodide (KI) alkali metal halides ...
Stabilization of Black FAPbI3 Perovskite by Interaction with the Surface of the Polymorphic Phase α-PbO
(Wiley-VCH GmbH, 2023-02-03)
The black phase of formamidinium lead iodide, FAPbI3, is optically active and promising for optoelectronics applications. However, it is difficult to synthesize and stabilize at room temperature since it thermodynamically ...
Unlocking a (Pseudo)-Mechanically Interlocked Molecule with a Coronene “Shoehorn”
(Wiley, 2023)
Mechanically interlocked molecules (MIMs) have gained increasing interest during the last decades, not only because of their aesthetic appeal, but also because their unique properties have allowed them to find applications ...
2D-Self-Assembled Organic Materials in Undoped Hole Transport Bilayers for Efficient Inverted Perovskite Solar Cells
(American Chemical Society, 2023-05-10)
Interfaces between photoactive perovskite layer and selective contacts play a key role in the performance of perovskite solar cells (PSCs). The properties of the interface can be modified by the introduction of molecular ...
Enhanced efficiency and stability in Sn-based perovskite solar cells by trimethylsilyl halide surface passivation
(Elsevier, 2022-05-13)
Lead free tin perovskite solar cells (PKSCs) are the most suitable alternative candidate for conventional lead perovskite solar cells. However, the efficiency and the stability are insufficient, mainly because of the poor ...
