Summary: This article presents a miniaturized 3-D magnetic resonance imaging (3-D-MRI) scanner that utilizes a high-voltage silicon-on-insulator (HV-SOI) CMOS application-specific integrated circuit (ASIC). The scanner, weighing 42 kg, integrates a 0.52-T permanent magnet and electronics onto a 6-mm2 silicon chip, providing a field of view (FOV) of 10 x 8 x 8 mm(3) for non-invasive probing of internal structures. The ASIC incorporates a high-voltage-enabled transmitter (TX), low-noise receiver (RX), and deep trench isolation (DTI) for enhanced noise performance and substrate noise immunity. The scanner achieves a high resolution of 110 x 117 x 250 (mu)m3 in a short acquisition time of 0.17 min using digital-to-analog converter (DAC)-based gradient control for 3-D spatial encoding.

Summary: This article investigates distance-based formation control for a group of nonlinear multiagent systems over directed graphs. A distributed, distance-based formation control scheme is proposed for heterogeneous, nonlinear agents in a 3-D space, specifically directed trilateral Laman graphs. Each directed edge is controlled by only one adjacent agent. The control method for nonlinear agents is designed using state-dependent Riccati equation. Stability of the overall formation is rigorously proven based on mathematical induction and cascade interconnected systems theory. A combination of signed area and volume constraints is applied to prevent agents from converging to flip-ambiguous frameworks in 3-D space. The proposed control law ensures collision avoidance between neighboring pairs of agents. Simulation results are provided for verification.

Summary: This article presents a simulation-based study on the variability of remnant polarization (P-r) in a multigranular 3-D ultrathin ferroelectric (FE) capacitor. The study finds that the amount of variability in Pr increases as FE thickness decreases, and that FE with a smaller surface area exhibits a higher variability in P-r compared to a larger surface area FE capacitor. Furthermore, the impact of dielectric content in the FE grains on the hysteresis loop is analyzed, showing that dielectric grains cause a large amount of variability and a loss in retentivity.

Summary: Cycloparaphenylenes (CPPs) and carbon nanobelts (CNBs) are cyclic molecular nanocarbons with unique properties derived from rigid, strained, and cyclic p-conjugated systems. The synthesis of various sizes of CPPs and CNBs has allowed for the investigation of their size-dependent properties and use in various applications. The synthesis, size-dependent properties, and paratropic belt currents of methylene-bridged [n]cycloparaphenylenes ([n]MCPP, n = 6, 8, 10) were reported and studied.

Summary: This article proposes a 3-D topology evolution scheme with self-adaption for mining areas (3D-TES) to reduce energy consumption. It builds a multipeak terrain model and quantifies the strength of node signals based on slope and aspect, then determines the optimal number of sink nodes and data transmission path. Experimental results show that 3D-TES outperforms the directed angulation toward the sink node model (DASM) in reliability, average path length, and data load on sink nodes.

Summary: In this study, the electron acceptor capacities of several anionic ligands incorporated into linear d (10), square planar d (8), and octahedral d (6) transition-metal complexes were ranked using ETS-NOCV data. The best acceptors were BI2 (-) and B-(CF3)(2) (-). It was found that many anionic ligands exhibit similar acceptor capacities, regardless of the d electron count. Additionally, the acceptor capacity decreases down a period but increases down a group for peripheral substituents.

Summary: Nonlinear ultrasonic methods are effective in detecting microdefects due to their high sensitivity, but the nonlinearity of ultrasonic equipment limits their full-scale use. This work proposes a material-enabled filter using phononic crystals (PCs) to eliminate the inherent nonlinearity. The PCs, made of mass blocks and connective layers, are processed using PLA. They successfully open a transmission gap and improve the nonlinear detection of microdefects in aluminum plates, providing a useful methodology for PC-based nonlinear detection in the NDT field.

Summary: Both compounds synthesized from the 1,4-benzenedicarboxylate (BDC2-) ligand and the viologen analog 1-(4-carboxyphenyl)-4,4'-bipyridinium (PCV). PCV ligands coordinate with metal atoms to form 1D zigzag chains, further bridged by BDC2- ligands to yield a wave-like layer with a (4, 4) net topology. Compound 1 has a triple-layer structure stacked through van der Waals's force along the b direction, while compound 2 has a double-layer structure further interpenetrating into a 3D structure with lattice water molecules in channels along the a direction. Both compounds exhibit photochromism and decreased photoluminescence upon irradiation, with potential application as an inkless and erasable print medium for compound 1.

Summary: Introduction of photochromic properties into semiconductors allows for smart behaviors, color-related applications, and new modulation approaches. This study demonstrates that photoexcitation of the pi-aggregate of viologen cation radicals can efficiently trigger reverse electron transfer, leading to the discovery of the first single-component all-optically photochromic semiconductor. This discovery challenges the traditional concept that viologen compounds cannot undergo light-induced reverse reactions and offers a potential avenue for achieving all-optical switches in single-component photochromic smart semiconductors based on electron-transfer functional motifs.

Summary: Constructing heterojunctions is an effective method to enhance charge separation in photocatalysts, but the traditional constructing processes are usually conducted at high temperatures or require expensive exotic species. This study proposes a novel photobreeding method, which enables the direct growth of Zn nanowires and Mott-Schottky heterojunctions from ZnS microspheres without external species at room temperature. The hydrogen production efficiency of the photocatalysts is greatly improved after photobreeding, making this method a promising approach for various applications.

The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
