such as large surface area, high porosity and enhanced interactions with drugs and cells. While nanocellulose has been shown to have low toxicity [23], there are key variables that have been reported to affect toxicity including size, morphology, crystallinity, surface chemistry and stability [24]...

be removed through evaporation in dry conditions. The tar-coated paper is intended to provide both a vapour- and water-proof barrier below the timber cladding. It is unlikely that such a system would function well in a maritime climate.
For green and sustainable chemistry, molecular oxygen is considered as an ideal oxidant due to its natural, inexpensive, and environmentally friendly characteristics, and therefore offers attractive academic and industrial prospects. Thiscritical reviewintroduces the recent advances over the past 5 years in...
Recycling cycles cause a decrease in mechanical paper properties due to cellulose fiber degradation. The use of cellulose micro/nanofibers (CMF/CNF) to reinforce paper strength has been well studied, although it has been found to have negative effects on drainage. However, the application of CMF/...
