Summary: The study presents a method to fabricate flexible and superhydrophobic foam composites for efficient oil/water separation by decorating carbon nanofibers (CNFs) with a hollow structure uniformly onto the polydimethylsiloxane (PDMS) foam skeleton. The CNFs not only enhance the surface roughness and hydrophobicity, but also act as numerous capillary tubes, improving oil adsorption and oil/water separation performance. The CNFs network with strong light absorption enables the foam material to have superior photo-thermal conversion capability, excellent corrosion resistance, and the ability to adsorb various kinds of oil with different densities, resulting in high oil/water separation efficiency.

Summary: The development of a superhydrophobic copper mesh for efficient oil/water separation was investigated in this study. A monolayer graphene/polydimethylsiloxane (PDMS) mixture was coated on the copper mesh to enhance its hydrophobic properties. By combining graphene with different ratios of PDMS, the effect on the contact angle of the fabricated meshes was examined. Irradiation with a Nd:YAG -1064 nm laser improved the hydrophobicity of the surface, with the best result achieved at a laser-to-sample distance of 1.5 mm above the laser focal point. The developed graphene@Cu mesh showed a contact angle of 155.6o +/- 0.3 and demonstrated high separation efficiencies of 92% for HD-40 engine oil and 95% for toluene.

Summary: The air trap plays a crucial role in regulating air bubbles and clots in hemodialysis systems, and the quality of the micro-filter inside it affects the risk of emboli transmission to patients. This study aims to optimize the injection molding process of a dialysis micro-filter to maximize part quality by minimizing shrinkage, weight, and clamping force. Through CT diagnosis and simulation using AMA, the injection molding process was fine-tuned, with injection time identified as the most influential factor. Multi-response optimization yielded ideal settings for reduced shrinkage, weight, and clamp force, enhancing overall part quality and patient safety.

Summary: This study used fused deposition modeling method to fabricate a poly e-caprolactone (PCL) scaffold, and filled it with Alginate (Alg): Alginate-Sulfate (Alg-Sul) hydrogel to create a biomimetic environment and mimic the structure of glycosaminoglycans. Different concentrations of decellularized extracellular matrix (dECM) were added to enhance chondrogenesis. Cellular analyses showed that the scaffold with 1% dECM exhibited better viscosity, cell viability, and proliferation. Mechanical characterization and chondrogenic differentiation tests demonstrated that the optimized scaffold (1% dECM) had similar mechanical properties to native nasal cartilage tissue and appropriate biochemical features.

Summary: Developing water-saving technologies like Groasis Waterboxx (GW) using environmentally friendly materials has emerged as a robust strategy to reduce the negative impact of agriculture on the environment and society. In this study, injection molding of green GWs made of poly-lactic acid (PLA) and polybutylene succinate (PBS) was simulated, and the performance of the parts in harsh conditions was analyzed. The simulation results showed that PLA had faster production speed compared to polypropylene (PP), while PBS demonstrated mechanical qualities similar to PP and provided a high safety factor. Despite consuming more energy for injection, substituting PP with PBS is justified considering its efficiency and eco-friendliness.

Summary: The development of organ-on-a-chip (OoC) systems is a creative method to effectively model human drug responses in preclinical research. These systems simulate the complexity of human tissues and offer accurate screening results, which are often missing in traditional screening tools. Microfluidics and microfabrication techniques are powerful tools for designing systems that accurately simulate in vivo microenvironments for drug delivery, discovery, development, and screening. This approach has the potential to study cell responses to pharmacological and mechanical stimuli in a more biologically effective manner.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
