Space Division Multiplexing (SDM) and Spatial Super-Channel (Spa SCh) technology provide scalable solutions to meet the growing capacity demands of optical networks. This study focuses on multi-fiber optical networks integrated with innovative Spa SChs, enabling the creation of various Spa SCh granularities by spatially combining the same spectrum across multiple fibers, a transmission method referred to as Fiber-SDM (FSDM). To assess the performance of the FSDM-based network, we develop an analytical model to predict the blocking probability (BP) of Spa SChs with different granularities. Additionally, we propose an efficient adaptive Routing, Fiber, and Spectrum Assignment (RFSA) algorithm, based on the concepts of Spatial Spectrum Window (SSW) and the SSW plane (SSWP). Simulations are conducted to evaluate lightpath BP, considering the trade-off between system cost and power consumption. The results demonstrate the accuracy of the analytical model in predicting lightpath BP in the FSDM network. Furthermore, the Adaptive SSW Plane (A-SSWP) algorithm outperforms the benchmark RFSA algorithms, achieving the best performance under an optimal Spa SCh configuration. © 1983-2012 IEEE.

Integrated electro-optic modulators with large bandwidth, high linearity and low driving voltage are key building blocks for integrated microwave photonic (IMWP) links to transmit broadband signals with high fidelity. In this work, thin-film lithium niobate electro-optic modulator consisting of a thermo-optic reconfigurable coupler and dual-parallel Mach-Zehnder modulation scheme is proposed and demonstrated to achieve spurious-free dynamic range of 112.87/107.71 dB·Hz2/3 at 1/10 GHz while keeping large bandwidth (>67 GHz) and low half-wave voltage (2.7 V) simultaneously. The demonstration of this device paves a new route for high-performance electro-optic modulators in future functional IMWP systems. © 2025 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.

Inducing room-temperature superparamagnetism in graphene quantum dots (GQDs), which can afford them various applications in nanoscale spintronic devices and quantum-information devices, remains a challenge due to the difficulty in atomically accurate fabrication of magnetic zigzag edges. Here, we report the realization of superparamagnetism in GQDs by high-concentration semi-ionic fluorine functionalization on the basal plane of GQD sheets. The functionalized GQDs with an average size of about 2.67 nm and a semi-ionic fluorine concentration as high as up to 18.3 atom % exhibit clear superparamagnetism with nearly zero coercivity and remanence magnetization and a near-room-temperature Curie temperature of 275 K. Our findings highlight the effectiveness of semi-ionic fluorine functionalization in inducing superparamagnetism in GQDs. © 2025 American Chemical Society.

Aluminum (Al) exhibits excellent electrical conductivity, mechanical ductility, and good chemical compatibility with high-ionic-conductivity electrolytes. This makes it more suitable as an anode material for all-solid-state lithium batteries (ASSLBs) compared to the overly reactive metallic lithium anode and the mechanically weak silicon anode. This study finds that the pre-lithiated Al anode demonstrates outstanding interfacial stability with the Li6PS5Cl (LPSCl) electrolyte, maintaining stable cycling for over 1200 h under conditions of deep charge–discharge. This paper combines the pre-lithiated Al anode with a high-nickel cathode, LiNi0.8Co0.1Mn0.1O2, paired with the highly ionic conductive LPSCl electrolyte, to design an ASSLB with high energy density and stability. Using anode pre-lithiation techniques, along with dual-reinforcement technology between the electrolyte and the cathode active material, the ASSLB achieves stable cycling for 1000 cycles at a 0.2C rate, with a capacity retention rate of up to 82.2%. At a critical negative-to-positive ratio of 1.1, the battery’s specific energy reaches up to 375 Wh kg−1, and it maintains over 85.9% of its capacity after 100 charge–discharge cycles. This work provides a new approach and an excellent solution for developing low-cost, high-stability all-solid-state batteries. (Figure presented.) © The Author(s) 2025.

A Stability-Enhanced Intelligent Absorbent Pad by Tannic Acid Co-pigmentation for Pork Freshness Monitoring

In order to improve the stability of anthocyanins in freshness indicator packaging, this study initially co-pigmented blueberry anthocyanins (BA) with tannic acid (TA). Subsequently, fiber absorbent pads were soaked in the treated solutions to create stable freshness indicator pads. By investigating the effects of TA addition on both the BA solution and the pads properties, the results revealed that TA significantly enhanced the light stability, thermal stability, and pH stability of the BA solution. Fourier transform infrared spectroscopy and X-ray diffraction also showed that co-pigmentation could promote the molecular interaction between BA and TA to form a more stable structure. Furthermore, the antioxidant properties and swelling capabilities of the pads were significantly improved by varying levels of TA, with the BA-0.5TA group exhibiting 12.20% and 66.88% higher values, respectively, compared to the pure BA group. Notably, the pads containing TA demonstrated excellent color responsiveness to different pH buffer and volatile amines (with 2 min). Meanwhile, the hydrogen bond formed between TA and BA and van der Waals forces effectively improved the storage stability of BA pad. During storage, the BA-0.5TA also changed from bright red to blue-white when pork deterioration was monitored. These results suggest that the BA-TA high stability pad holds promising potential as an intelligent freshness indicator package. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2025.

In response to the global demand for high-quality protein, Litopenaeus vannamei aquaculture has rapidly expanded. However, microalgal blooms often degrade water quality, resulting in reduced yields and significant financial losses. This study investigated the recovery dynamics of substrate microalgae, which act as seed banks for microalgal blooms, and identified early warning thresholds for algae under varying environmental conditions. Sediments from bfIGuccess (BS) and breeding failure (BF) sheds were analyzed to evaluate the effects of temperature (6 °C–21 °C), light intensity (50–2,000 lx), and nutrient types (BG11 and raw water). The findings indicated that environmental factors influencing microalgal recovery followed the priority order: temperature > light > nutrient salts. The highest recovery was observed at temperatures of 11 °C and 16 °C under 2,000 lx illumination. key early warning algal species, including Melosira granulata, Cyclotella, and Chlorella, exhibited thresholds of 0.9–42.9 × 104 cells/g, 0.1–28.8 × 104 cells/g, and 1.0–31.7 × 104 cells/g, respectively. This study uniquely linked substrate algae recovery to aquaculture failures, providing quantitative thresholds and actionable insights for proactive microalgal blooms monitoring and control. These findings form a scientific basis for improving water quality management and ensuring sustainable L. vannamei aquaculture © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2025.
