Figure 1 (a-c) were incorrectly assigned in the caption. The correct legend should read: "a-c) Photographs of the cellulose hydrogels: (a) physically cross-linked cellulose hydrogel, (b) DC cellulose hydrogel, and (c) chemically cross-linked cellulose hydrogel under bending." A reflection peak was incorrectly assigned throughout the manuscript. All occurrences of (200) should be changed to (110). All reflections labeled initially (110) in the manuscript instead represent (110) In consequence two passages on page 6282 should read as follows: "…which correspond to the (110) and (110) reflections, respectively, of cellulose II crystallite. [26] Therefore, …resulted from the (110) reflection of the cellulose II crystallite hydrates…". and "…the intensity of the peak at 20.2° for the (110) reflection of the cellulose II crystallite hydrates gradually increased, …" in addition text on page 6283 should appear as "Moreover, the intensity of the (110) reflection of the DC cellulose hydrogels increased as the concentration of aqueous ethanol increased…" and the corrected version of Figure 3 should appear as shown below: correction Figure 3. X-ray diffraction profi les of the PC cellulose hydrogel, DC cellulose hydrogel, and CC cellulose hydrogel prepared using a) different ECH-to-AGU molar ratios and b) different concentrations of aqueous ethanol. The above errors do not affect the scientific conclusions drawn from the work. The authors apologize for any inconvenience or misunderstanding that these errors may have caused.

A non-porous and amorphous fluoropolymer PFN with low dielectric constant of 2.33 and dielectric loss less than 1.2 × 10(-3) is reported here. PFN also exhibits good mechanical properties and high thermostability. This study is a new example of a fully dense material showing a low k value and having good thermo/mechanical properties.

The knowledge base for nanocellulose (NC) has grown exponentially over the past two decades and continues to expand with the increasing number of potential applications demonstrated in the literature and the patent space. NC has multiple forms depending on the starting cellulose source and the specific process used to produce it. Its high degree of surface reactivity makes it an ideal support structure for a wide variety of functional groups, leading to the ability to engineer materials for very specific applications. However, removing water from an NC suspension, e.g., dewatering and drying, while retaining the nanoscale properties of the NC remains a significant challenge to successful commercialization of NC materials. Processes for dewatering and drying of NC are desirable because of the high transport costs of shipping dilute aqueous suspensions, as well as end-use application requirements. Therefore, the development of nondestructive, cost-effective, scalable, and environmentally friendly dewatering and drying processes is important for commercial deployment of NC applications. This review addresses the current state of published knowledge on NC dewatering and drying and identifies research gaps that could be further explored in a precompetitive context to accelerate commercialization.

Collagen I (Col-I) is widely used in the fabrication of biomaterials due to its biocompatibility; however, Col-I based biomaterials are susceptible to mechanical failure during handling, which limits their applicability to biomaterials. Chemical or physical treatment can improve the mechanical properties of collagen; however, these processes can create issues of cytotoxicity or denaturation. We report here an alternative strategy to improve the stability and mechanical properties of Col-I while preserving its native structure, through thermal treatment in fluorous media. Thermal treatment of Col-I in fluorous solvent generates compact, stable films with significantly increased mechanical strength. Furthermore, the use of fluorous media significantly reduces the extent of swelling and the rate of proteolytic degradation, but it preserves the high cell biocompatibility.

The production of cellulose nanofibrils (CNFs) continues to receive considerable attention because of their desirable material characteristics for a variety of consumer applications. There are, however, challenges that remain in transitioning CNFs from research to widespread adoption in the industrial sectors, including production cost and material performance. This Review covers CNFs produced from nonconventional fibrillation methods as a potential alternative solution. Pretreating biomass by biological, chemical, mechanical, or physical means can render plant feedstocks more facile for processing and thus lower energy requirements to produce CNFs. CNFs from nonconventional fibrillation methods have been investigated for various applications, including films, composites, aerogels, and Pickering emulsifiers. Continued research is needed to develop protocols to standardize the characterization (e.g., degree of fibrillation) of the lignocellulosic fibrillation processes and resulting CNF products to make them more attractive to the industry for specific product applications.
