Summary: Supramolecular polymer materials are physically crosslinked polymeric structures that exhibit stimuli-responsive behavior and healable properties due to noncovalent interactions. The incorporation of the quadruple hydrogen bonding unit UPy in polymeric precursors has led to the development of a wide range of hydrogen bonded materials with diverse applications. This review focuses on the design strategies to synthesize UPy-containing polymer materials and discusses their material properties.

Summary: In this paper, a computational storage platform based on SmartSSD CSD is proposed to accelerate graph-based nearest neighbor search algorithm. By modifying the algorithm for hardware compatibility and implementing two types of accelerators using HLS and RTL methods, the proposed platform achieves high performance. Furthermore, with the expansion of the platform scale and the application of graph parallelism, the system performance is further boosted. The computational storage platform achieves a throughput of 75.59 queries per second for the SIFT1B dataset at 258.66W power dissipation, which is significantly faster and more energy efficient than conventional CPU and GPU-based server platforms. With its multi-terabyte storage and custom acceleration capability, the proposed computational storage platform is considered a promising solution for cost-sensitive cloud datacenters.

Summary: Large-scale mass transport driven by the difference in photoisomerization-induced surface tension was demonstrated in ion pairs of anionic azobenzene and a cationic polymer. This material motion enabled fluorescence patterning using a trace amount of photoisomerized azobenzenes in complex form with a pi-electronic system.

Summary: Supramolecular chemistry allows for manipulation of functional components at the molecular scale, leading to the creation of supramolecular materials with controlled sizes and structures. Pillar[n]arene, a novel macrocyclic host, has attracted significant interest due to its distinctive electron-rich cavity and finely adjustable rims. Its straightforward synthesis, uncomplicated functionalization, and remarkable properties make it an excellent candidate for material construction, especially in the generation of interpenetrating supramolecular polymers. These polymers show potential in various applications such as fluorescence sensors, substance adsorption and separation, catalysis, light-harvesting systems, artificial nanochannels, and drug delivery.

Summary: This study evaluates the impact of transferring computationally intensive tasks to the GPU in solving compressible reacting flow problems. The workflow and data transfer penalties of plugging in a GPU-based chemistry library into CPU-based and GPU-based solvers are compared. The results show that offloading the source term computation to the GPU leads to a significant reduction in solution time and faster computation compared to CPU-based methods.

Summary: A low-molecular-weight supramolecular gel electrolyte (SGE) has been successfully developed for quasi-solid-state supercapacitors (QSSCs), which shows comparable performance dependence on electrode thickness as bulk electrolyte solutions. The high ionic conductivity and good wettability of the SGE contribute to its effective filling of thick porous activated carbon electrodes.

Summary: Research shows that with the exponential growth of data generated by edge computing, the decentralized and Gossip-based training of deep learning models is gaining momentum. The EdgeGossip framework is designed to reduce the performance variation among heterogeneous edge platforms during training and achieve best possible model accuracy quickly. Implementing EdgeGossip based on popular Gossip algorithms has demonstrated an average reduction of model training time by 2.70 times with only 0.78% accuracy loss.
