Summary: Incorporating titanate nanowires into the cellulose acetate matrix allowed the formation of a nanocomposite membrane with modified characteristics. The synthesized membranes showed a dense, uniform membrane formation with a highly dispersed inorganic phase when low amounts of particles were added. Testing the membranes showed an increase of three times in water flux, reaching from 1.33 to 4.0 L/h m(2), with NaCl rejection over 65%.

Summary: Cellulose and its derivatives are commonly used as nanofibrous biomaterials, but research on obtaining 3D cellulose nanofibers is limited. This study presents a simple method for converting electrospun 3D cellulose acetate/lactic acid nanofibers into a 3D cellulose/calcium lactate nanocomposite matrix, resulting in a stronger and more cell-friendly material suitable for bone tissue engineering. The successful conversion was verified through various analytical techniques, and the scaffolds were found to provide a suitable environment for cell growth and infiltration.

Summary: This study synthesized a series of CA/PVP membranes with different ratios using a 2-stage phase inversion protocol, and investigated their ion dialysis separation performance. The membranes were further modified with varying amounts of f-SWCNTs, leading to improved thermal stability, hydrophilicity, and ions separation factor. The addition of f-SWCNTs resulted in decreased pure water flux but enhanced ion separation, with the CPC3 membrane infused with 0.5 wt% of f-SWCNTs demonstrating the best overall performance.

Summary: Cigarette butts are commonly littered wastes in society, and it is important to find a feasible way to valorize them. In this study, cellulose acetate from cigarette butts was used to prepare macroporous cellulose microspheres through an emulsion-evaporation-induced phase separation method. The resulting microspheres had controlled pore sizes and were chemically modified to achieve a cationic adsorbent with excellent adsorption capacity and mechanical strength. These low-cost and eco-friendly microspheres show great potential for bio-separation.
