Additionally, industrial white-water samples collected at the beginning and at the end of a paper production run were used in refining and handsheet preparation processes. Comparing the two types of pulp, HYP exhibited superior internal bond strength properties than LYP, attributed to the increased relative bonded area due to the presence of lignin.

During storage and disposal, both radiolytic and hydrolytic degradation of such materials can be expected, the latter triggered by the highly alkaline cementitious environment of the waste matrix and disposal facility. The combination of both degradation processes will cause a significant production of radionuclide-complexing agents, which can enhance the migration of certain radionuclides towards the biosphere. Knowledge regarding the degradation mechanisms is therefore required to predict the long-term production rate of these organics. In this study, the physicochemical properties of cellulosic tissues during radiolytic and/or alkaline degradation under disposal conditions were monitored. Our results indicate that the long-term alkaline degradation of cellulose is controlled by two underlying mechanisms, taking place in both the amorphous and the crystalline regions. The first one is a combination of peeling and stopping reactions taking place at the easily available reducing end groups in the amorphous regions of cellulose. This process controls the overall degradation rate until the easily accessible reducing end groups become depleted. Afterwards, the degradation slows down significantly and is rather controlled by a continuous stepwise dissolution and amorphization of the outer layer of crystalline cellulose, resulting in the liberation of reducing end groups, where secondary peeling reactions can take place. These new insights lead to a better-founded choice of the conceptual model for predicting the long-term cellulose degradation in radioactive waste.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 7","pages":"4363 - 4385"},"PeriodicalIF":4.9,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-025-06499-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, nitrocellulose hydrophobicity requires surfactants to increase membrane wettability. The aim of this work is to manufacture a microfluidic paper-based analytical device (µPAD) composite of a microfibrillated cellulose matrix (MFC) embedded with microcrystalline cellulose (MCC) and silicon oxide particles (SiO<sub>2</sub>) to manage water uptake and fluid flow kinetics within the fluidic strip. Several composite inks were formulated by varying the MFC, MCC and SiO<sub>2</sub> mass fractions, and the impact of particle size and mass fraction of the composite on water uptake was compared. An additive manufacturing technique was assessed using a fluid dispenser mounted on a 6-axis robot to manufacture the cellulose-based strips. One key objective was to develop a µPAD as an alternative to nitrocellulose-based POC devices. The µPAD composite was assessed with a migration test in a lateral flow configuration. Promising results were obtained by producing strips with a water capillary rise of 4 cm in 5 min, comparable to the performance of nitrocellulose.
