The future deployment of terawatt-scale proton exchange membrane water electrolyzer (PEMWE) technology necessitates development of an efficient oxygen evolution catalyst with low cost and long lifetime. Currently, the stability of the most active iridium (Ir) catalysts is impaired by dissolution, redeposition, detachment, and agglomeration of Ir species. Here we present a ripening-induced embedding strategy that securely embeds the Ir catalyst in a cerium oxide support. Cryogenic electron tomography and all-atom kinetic Monte Carlo simulations reveal that synchronizing the growth rate of the support with the nucleation rate of Ir, regulated by sonication, is pivotal for successful synthesis. A PEMWE using this catalyst achieves a cell voltage of 1.72 volts at a current density of 3 amperes per square centimeter with an Ir loading of just 0.3 milligrams per square centimeter and a voltage degradation rate of 1.33 microvolts per hour, as demonstrated by a 6000-hour accelerated aging test.

With the deep integration of cyber tools, control algorithms are increasingly employed in cyber-physical energy systems to enhance management, cost efficiency, and robustness. Effective demand load management is crucial in cyber-physical energy systems as it directly impacts operational costs. Failure to adequately manage spiky or seasonal demand loads can lead to significant expenses on monthly utility bills. In this study, we propose AMPAMOD, a randomized online algorithm with machine-learned advice, to optimize battery operations and mitigate highly dynamic peak loads. AMPAMOD utilizes limited advice from machine learning algorithms to guide our online algorithm and ensure cost-effective peak load management. The theoretical analysis shows that our solution has minimal advice complexity, a linear computational cost, and an improved competitive ratio. Finally, we conduct extensive trace-driven experiments on real-world datasets. AMPAMOD achieves a peak shaving success rate of over 90%, outperforming baselines by at least 50%. These experimental results confirm theoretical findings and demonstrate the potential of AMPAMOD. © 2023 IEEE.

Reed-Solomon (RS) codes are widely applied in storage systems. The main bottleneck of RS codes is that the high decoding complexity defined as the number of multiplications and additions. In this paper, we propose a fast decoding algorithm for RS codes that requires fewer number of multiplications. Our fast decoding algorithm is designed by a decomposition of Vandermonde matrices. We show that our decoding algorithm requires fewer number of multiplications than the existing best known algorithm when the number of parities T is large. When the codeword length N=16, our decoding algorithm reduces the number of multiplications by 7% and 29% when T=4 and T=7, respectively, compared with the best known decoding algorithm. © 2024 IEEE.

Metal halide perovskites (MHPs) possess advantageous optoelectronic properties, so perovskite emitters and perovskite light-emitting diodes (PeLEDs) are promising candidates for next-generation high-colour-purity displays and lighting applications. Within the past 5 years, the luminescence efficiency of MHP emitters and PeLEDs has increased rapidly. However, the industrial applications of perovskites are impeded by several technical bottlenecks, such as insufficient colour reproducibility, low operational stability, toxicity and limited large-scale production. In this Review, we survey the current status of MHP emitters and PeLEDs and provide a technical roadmap to highlight the goals and requirements for them to successfully enter the markets for vivid displays with high colour purity, augmented and virtual reality displays and general and special lighting. We also set out steps for future research in MHPs and their device applications.

This paper reports a facile, high-resolution, and cleanroom-free technique to fabricate grooved microneedles for ISF sampling using capillary action. A master mold for grooved MN array with high aspect ratio is fabricated using two photon polymerization based 3D printer. Biocompatible photo-curable resin is casted into molds to realize microneedles;molding makes this approach scalable for large volume production. A sodium polyacrylate-based bead is placed on the distal end of the grooved microchannels as an absorbent to sustain interstitial fluid (ISF) sampling. The ISF is easily recovered from the swollen sodium polyacrylate beads for further analysis. The MNs' continuous fluid extraction has been successfully tested and validated in the lab. © 2022 MicroTAS 2022 - 26th International Conference on Miniaturized Systems for Chemistry and Life sciences.

Patterned nanomagnet arrays (PNAs) have been shown to exhibit a strong geometrically frustrated dipole interaction. Some PNAs have also shown emergent domain wall dynamics. Previous works have demonstrated methods to physically probe these magnetization dynamics of PNAs to realize neuromorphic reservoir systems that exhibit chaotic dynamical behavior and high-dimensional nonlinearity. These PNA reservoir systems from prior works leverage echo state properties and linear/nonlinear short-term memory of component reservoir nodes to map and preserve the dynamical information of the input time-series data into nondelay spatial embeddings. Such mappings enable these PNA reservoir systems to imitate and predict/forecast the input time series data. However, these prior PNA reservoir systems are based solely on the nondelay spatial embeddings obtained at component reservoir nodes. As a result, they require a massive number of component reservoir nodes, or a very large spatial embedding (i.e., high-dimensional spatial embedding) per reservoir node, or both, to achieve acceptable imitation and prediction accuracy. These requirements reduce the practical feasibility of such PNA reservoir systems. To address this shortcoming, we present a mixed delay/nondelay embeddings-based PNA reservoir system. Our system uses a single PNA reservoir node with the ability to obtain a mixture of delay/nondelay embeddings of the dynamical information of the time-series data applied at the input of a single PNA reservoir node. Our analysis shows that when these mixed delay/nondelay embeddings are used to train a perceptron at the output layer, our reservoir system outperforms existing PNA-based reservoir systems for the imitation of NARMA 2, NARMA 5, NARMA 7, and NARMA 10 time series data, and for the short-term and long-term prediction of the Mackey Glass time series data. © 2024 IEEE.

The need for a building with a green building concept is now very important for environmental conservation. The concept of green building is to design a building that has a more efficient consumption of electrical energy. The Energy Consumption Intensity (ECI) of a building in Indonesia with a tropical climate is regulated in SNI no 03-0196: 2010. In this standard, the ECI of an air-conditioned building is said to be efficient if it has a consumption of 7.93-12.08 kWh/M2/month. Meanwhile, according to the Indonesian Green Building Council (GBCI), the ECI in Green Building is 50% of a conventional building. In this study, electrical energy consumption was measured for at least 1 year. The research location is the Head Office Building of PT Indonesia Asahan Aluminium (Persero), a State-Owned Enterprise located in Batubara Regency, North Sumatra, Indonesia. According to the results of the analysis of existing data, it can be concluded that the Inalum Building has an efficient electricity consumption intensity according to SNI standards, with a value of 78.34 kWh/m2/year or 6.53 kWh/m2/month. However, as a green building, the existing air-conditioned space still has an ECI value that exceeds the specified standard. According to the SNI standard classification, this building is still considered energy-intensive because the ECI value of an air-conditioned room is 243.56 kWh/m2/year or 20.29 kWh/m2/month. The novelty that we get in this research is the actual Energy Consumption Intensity (ECI) indexes of this green building. © 2022 IEEE.
