Abstract: Nanocellulose-based composite aerogels have the advantages of high porosity, biodegradability, and biocompatibility, with wide applications in many fields, such as adsorption, separation, energy storage, and heat insulation. In this study, a nanocellulose-based composite aerogel (NCA) was prepared using the one-pot method with cellulose nanofibrils (CNFs), tannic acid (TA), and polyvinyl alcohol (PVA) as raw materials. The adsorption behaviors of Pb2+, Cd2+, and Cu2+ were also studied. FT-IR ana[...]
Our summary: Study on the adsorption behavior of a nanocellulose-based composite aerogel for Cu(II), Cd(II), and Pb(II) heavy metal ions. High porosity, biodegradability, and biocompatibility make nanocellulose-based composite aerogels versatile in various applications. The study prepared a nanocellulose-based composite aerogel using cellulose nanofibrils, tannic acid, and polyvinyl alcohol, showing excellent adsorption capacity for heavy metal ions.

Geopolymer-based concrete composition
Patent published on the 2025-06-26 in WO under Ref WO2025137733 by PLANTAER INC [US] (Abdallah Robert Joseph [us], Ruiz Manuel Jesus Benitez [us])
Abstract: Embodiments provide a novel concrete composition and method for forming a geopolymer-based building material. The composition comprises a geopolymer binder, water-retentive aggregates with long-term water retention properties and biological surface growth facilitation, where at least one aggregate is cellulose pre-treated with a saturating coating solution. The composition also includes rigid, porous aeration aggregates and strength aggregates. The method involves mixing these components to form[...]
Our summary: Novel geopolymer-based concrete composition with water-retentive aggregates, cellulose pre-treated aggregates, and aeration aggregates. Method involves mixing components to form pourable material, then curing under controlled conditions. Construction material includes aluminosilicate precursor, biopolymer-coated aggregates, and porosity agent for enhanced sustainability and durability.

Composite rotator cuff patch and preparation method therefor
Patent published on the 2025-06-12 in WO under Ref WO2025118346 by GUANHAO BIOTECH CO LTD [CN] (Mo Ziru [cn])
Abstract: Disclosed in the present application are a composite rotator cuff patch and a preparation method therefor. The composite rotator cuff patch is divided into an electrospun layer and a collagen layer. An electrospun nanofiber membrane is coated with a layer of cross-linked collagen gel, and then composite freeze-drying is carried out to obtain the composite rotator cuff patch of the present application. The rotator cuff patch has good biocompatibility and proper tissue adhesion, does not require s[...]
Our summary: Composite rotator cuff patch with electrospun and collagen layers, prepared by composite freeze-drying for good biocompatibility and tissue adhesion, no sutures needed for fixation, degrades in vivo without postoperative removal.

Characterization and Modelling of Biomimetic Bone Through Additive Manufacturing
Published on 2025-03-10 by Niranjan Srinivasan, Mohsen Barmouz, Bahman Azarhoushang @MDPI
Abstract: The long-term success of bone implant scaffolds depends on numerous factors, such as their porosity, mechanical properties, and biocompatibility. These properties depend on the type of material, such as metals and their alloys or ceramics, and the procedure used to create the scaffolds. This study aims to find the biomimetic properties of aluminum 6061 (Al 6061) alloy through Digital Light Processing (DLP) and sintering. Hollow cylindrical Al 6061 samples are printed through the DLP process at 9[...]
Our summary: Long-term success of bone implant scaffolds depends on porosity, mechanical properties, and biocompatibility. Study aims to find biomimetic properties of Al 6061 alloy through DLP and sintering. Scaffold model created with anisotropic properties closer to trabecular bone.
