The obtained performance is one of the highest performances in inverted perovskite layouts. The cut‐price and straightforward synthesis with elegant scale up makes these classes of materials important for the industry to produce high‐throughput printed perovskite solar cells for large area applications.]]> Wed 23 Jan 2019 10:40:21 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51677  92% Faradaic efficiency toward formate production with high current density which was associated with the synergistic effects between the CsPbI₃ NCs and rGO. ABSTRACT: Transformation of greenhouse gas (CO₂) into valuable chemicals and fuels is a promising route to address the global issues of climate change and the energy crisis. Metal halide perovskite catalysts have shown their potential in promoting CO₂ reduction reaction (CO₂RR), however, their low phase stability has limited their application perspective. Herein, we present a reduced graphene oxide (rGO) wrapped CsPbI₃ perovskite nanocrystal (NC) CO₂RR catalyst (CsPbI₃/rGO), demonstrating enhanced stability in the aqueous electrolyte. The CsPbI₃/rGO catalyst exhibited > 92% Faradaic efficiency toward formate production at a CO2RR current density of ~ 12.7 mA cm−2. Comprehensive characterizations revealed the superior performance of the CsPbI₃/rGO catalyst originated from the synergistic effects between the CsPbI₃ NCs and rGO, i.e., rGO stabilized the α-CsPbI₃ phase and tuned the charge distribution, thus lowered the energy barrier for the protonation process and the formation of *HCOO intermediate, which resulted in high CO₂RR selectivity toward formate. This work shows a promising strategy to rationally design robust metal halide perovskites for achieving efficient CO₂RR toward valuable fuels.]]> Wed 13 Sep 2023 15:22:05 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46039 Wed 09 Nov 2022 15:38:06 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:40168 H_∞ control problem for stochastic systems with disturbance preview, which is very challenging since it involves the preview problem and multiplicative noise simultaneously. The H_∞ control problem for deterministic systems with disturbance preview was once listed as one of the 53 open problems in mathematics and control, and its methods cannot be generalized to solve the corresponding stochastic problem because of the essential differences of the two classes of systems. Using the projection principle in indefinite space, we give a necessary condition of the solvable H_∞ preview control problem by using a pair of variables. The necessary condition is very useful for solving the minimax problem. An inertia condition of matrices, as the necessary and sufficient condition under which the H8 control for stochastic linear systems is solvable, is also proposed and tested. This condition generalizes the results for H_∞ control for deterministic systems with disturbance preview. Our results are demonstrated via a quarter vehicle active suspension system.]]> Wed 06 Jul 2022 11:39:44 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49156 Tue 14 Nov 2023 11:41:55 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37073 b:6,5-b′]dithiophene (TPA-NADT-TPA), 4,4′-(anthracene-2,6-diyl)bis(N,N-bis(4-methoxyphenyl)aniline) (TPA-ANR-TPA) and N²,N²,N⁶,N⁶-tetrakis(4-methoxyphenyl)anthracene-2,6-diamine (DPA-ANR-DPA), are designed and synthesized for use in organic light-emitting diodes (OLEDs) and perovskite solar cells (PSCs). In OLEDs, devices based on TPA-NADT-TPA, TPA-ANR-TPA and DPA-ANR-DPA showed pure blue, blue green, and green emission, respectively. Also, the maximum brightness of the devices with a turn-on voltage of 3.8 V reached 8682 cd m⁻² for TPA-NADT-TPA, 11 180 cd m⁻² for TPA-ANR-TPA, and 18 600 cd m⁻² for DPA-ANR-DPA. These new materials are also employed as hole transporting materials (HTMs) in inverted PSCs, where they were used without additives. The inverted devices based on these HTMs achieved an overall efficiency of 10.27% for TPA-NADT-TPA, 7.54% for TPA-ANR-TPA, and 6.05% for DPA-ANR-DPA under identical conditions (AM 1.5G and 100 mW cm⁻²). While the PSCs with TPA-NADT-TPA as the HTM achieved the highest efficiency, the DPA-ANR-DPA-based OLED devices showed the brightest emission and efficiency. Based on the obtained promising performance, it is clear that this molecular design presents a new research strategy to develop materials that can be used in multiple types of devices.]]> Fri 14 Aug 2020 13:34:14 AEST ]]>
