Summary: Effective integrated methods for oil-water separation and water remediation are of great significance in the energy and environment fields. Materials with both superlyophobic and superlyophilic properties are highly desirable due to their energy-saving and high-efficiency advantages. However, the introduction of low surface tension fluorinated components may lead to environmental harm and additional contamination. Therefore, the development of materials that can achieve both oil-water separation and removal of heavy metal contamination is crucial for industrial applications and environmental sustainability.

Summary: This study introduces a novel SUS membrane with excellent durability by incorporating polyhedral oligomeric silsesquioxane (POSS) nanoparticles on cotton fabric, followed by thiol-ene functionalization to graft hydrophilic carboxyl group. The membrane can withstand long-term mechanical abrasion, ultrasonic washing, UV light irradiation, and corrosive aqueous solutions without compromising underwater superoleophobicity. The membrane demonstrates high water fluxes, over 99% initial separation efficiencies for various oil/water mixtures, and maintained separation efficiency around 98% after 50 cycles under severe conditions. The findings of this study could contribute to the development of advanced SUS membranes with superior durability.

Summary: The development of functional membranes with easy operation, low cost, high stability, and large flux is urgently required for effective treatment of increasing oily wastewater. In this work, NaA zeolite/copper mesh composite membranes (NaA@CM) for oil/water separation were prepared using low-cost, readily available, and green metakaolin as the main raw material. The hydrothermal temperature was found to greatly affect the structure and properties of NaA@CM. The composite membrane prepared at 110 degrees C (NaA@CM-110) exhibited optimum underwater superoleophobicity, large water flux, and high separation efficiency for the cyclohexane/water mixture.

Summary: In this article, a coupled Tamm plasmon polaritons induced transmission theory was proposed to design high-efficiency narrow bandpass filters (NBPFs) with ultra-wide deep stopbands. An experiment with an NBPF at 1.55 mu m demonstrated a wider stopband and stronger restraint ability compared to traditional filters. This provides a powerful method for capturing specific narrowband optical signals from ultra-wide strong ambient light, particularly useful for daytime quantum communications.

Summary: Stereotactic radiosurgery (SRS) is the standard of care for brain metastases (BMs) patients. However, precise target delineation can be a time bottleneck in clinical workflow for patients with multiple BMs (mBMs). To address this, an automated BMs segmentation platform was developed, but its accuracy was influenced by false-positive segmentations caused by MRI contrast injection. To improve segmentation performance, a deep-learning and radiomics ensemble classifier was developed, consisting of a Siamese network and a radiomic-based support vector machine (SVM) classifier. The proposed model achieved high accuracy and effectively reduced false positives in BMs segmentation.

Summary: In this study, in-situ SEM tensile investigations were conducted to study the fracture mechanism and anisotropic behavior of selective laser melted and then heat-treated Ti6Al4V. The results showed that surface steps were formed during the plastic stage, and microcracks were mainly initiated by the separation or fracture of adjacent lamellae. Surface defects induced strain concentration and premature failure, while defects inside the specimens had little effect on ductility.

Summary: The friction and wear behaviors between cartilage replacement materials and articular cartilage are crucial for the function and performance of the replacements. This study investigated the difference between cross-shear motion and reciprocal linear motion on the frictional and wear behaviors of cartilage, as well as the effect of bearing surface roughness. The results showed that there was no significant difference between the two motion types. The water contact angle of the bearing surface affected the friction and wear behaviors for low roughness implants, while the surface roughness of the material affected the behaviors for high roughness implants. PEEK was found to be a suitable material for osteochondral implants.

Summary: The energy crisis is one of the most critical problems in modern society. Recently, emerging ionic thermoelectric materials have been widely used to harvest low-grade heat energy due to their excellent performance. However, the instability of ionic conductive materials in the underwater environment hinders underwater energy-harvesting. In this study, a water-resistant thermoelectric ionogel (TEIG) with excellent underwater stability was developed, providing a promising strategy for harvesting low-grade heat energy under water.
