Transparent wood composites provide new functionalities through active additives distributed at the nanoscale. Scalable nanotechnology includes processing where nanoparticles and molecules are brought into the dense wood cell wall. A novel cell wall swelling step through green chemistry is therefore investigated.

- The study aimed to create a clinical assessment protocol specifically for powerlifters experiencing low back and hip pain, addressing the lack of targeted information on their pain characteristics and functional impairments.
- The protocol was developed through a two-phase study, where phase one focused on creating the assessment based on existing literature, and phase two tested its feasibility with eight powerlifters, examining their pain and impairment through a structured evaluation by physical therapists.
- Results indicated that the protocol was effective, taking about an hour for examination, with consistent diagnoses between therapists, highlighting the importance of observing movement strategies during key exercises like squats and deadlifts.

Objective: To systematically review the literature on the incidence, prevalence, anatomical injury localisation and risk factors in Olympic weightlifting and powerlifting.
Design: Updated systematic review, PROSPERO registration (CRD42022382364).
Data Sources: Four databases (PubMed, Embase, SPORTDiscus and Web of Science) were searched on 19 February 2024.
Article Synopsis
- The study examines the environmentally friendly production of cellulose nanofibrils (CNFs) using varying amounts of the chemical TEMPO during the oxidation of softwood particles.
- It finds that using less TEMPO (down from 16 mg to 8 mg per gram of wood) still maintains strong properties in the resulting nanofibrils hydrogel networks, which are relevant for biomedical uses like wound dressings.
- The results indicate that the networks made from TEMPO-oxidized softwood nanofibrils exhibit impressive hydration abilities (up to 2500% absorption), elongation (up to 13%), and wet strength (around 190 kPa), supporting their potential use in healthcare.
Utilization of biomass and reuse of industrial by-products and their sustainable and resource-efficient development into products that are inherently non-toxic is important to reduce the use of hazardous substances in the design, manufacture and application of biomaterials. The hypothesis in this study is that spent mushroom substrate (SMS), a by-product from mushroom production, has already undergone a biological pretreatment and thus, can be used directly as a starting material for fibrillation into value-added and functional biomaterial, without the use of toxic substances. The study show that SMS can be effectively fibrillated at a very high concentration of 6.
