In this study, the viscosities of SA spinning dopes dramatically reduced to an order of magnitude lower while the maximum spin draw ratio increased from 1 to 6 as sodium polyacrylate (PAAS) loading increased up to 20 %. However, distinct to a simple plasticizing effect, adding appropriate amount of PAAS strengthens the mechanical properties of fully drawn fibers, through the formation of new physical crosslinks with SA. Fibers having the tenacity of ∼0.6 cN/dtex, modulus of ∼37 cN/dtex, strain at break of ∼7 % and toughness of ∼4 J/g were achieved with 15 % PAAS loading. Therefore, the PAAS addition has dual-effects in SA fiber wet spinning: to modify the rheology of the SA spinning solution and to strengthen the wet-spun SA fibers for textile applications.}, journal={CARBOHYDRATE POLYMERS}, author={Li, Shanshan and Biswas, Manik Chandra and Ford, Ericka}, year={2022}, month={Dec} } @article{biswas_ford_2022, title={Using Sodium Polyacrylate to Gel-Spin Lignin/Poly(Vinyl Alcohol) Fiber at High Lignin Content}, volume={14}, ISSN={["2073-4360"]}, url={https://doi.org/10.3390/polym14132736}, DOI={10.3390/polym14132736}, abstractNote={Lignin is the world’s most naturally abundant aromatic polymer, which makes it a sustainable raw material for engineered polymers and fiber manufacturing. Dry-jet gel-spinning was used to fabricate poly(vinyl alcohol) (PVA) fibers having 30% or more of the lignin biopolymer. To achieve this goal, 0.45 wt.% of aqueous sodium polyacrylate (SPA, at 0.55 wt.% solids) was added to spinning dopes of PVA dissolved in dimethylsulfoxide (DMSO). SPA served to enable the spinning of fibers having high lignin content (i.e., above 30%) while eliminating the aging of as-spun gel fiber prior to elevated temperature drawing. SPA impedes the migration of acetone soluble lignin from the skin of as-spun gel fibers, because SPA is insoluble in acetone, which is also a nonsolvent coagulant for PVA. PVA fibers having 30% lignin exhibited the highest tenacity of 1.3 cN/dtex (centinewton/decitex) and specific modulus 35.7 cN/dtex. The drawn fiber of 70% lignin to PVA, showed tenacity and specific modulus values of 0.94 cN/dtex and 35.3 cN/dtex, respectively. Fourier Transform Infrared (FTIR) spectroscopy showed evidence of hydrogen bonding between lignin and PVA among the drawn fibers. The modification of PVA/lignin dopes with SPA, therefore, allowed for the fabrication of gel-spun biobased fibers without the previously required step of gel aging.}, number={13}, journal={POLYMERS}, author={Biswas, Manik Chandra and Ford, Ericka}, year={2022}, month={Jul} } @misc{biswas_chakraborty_bhattacharjee_mohammed_2021, title={4D Printing of Shape Memory Materials for Textiles: Mechanism, Mathematical Modeling, and Challenges}, volume={31}, ISSN={["1616-3028"]}, url={https://doi.org/10.1002/adfm.202100257}, DOI={10.1002/adfm.202100257}, abstractNote={Abstract}, number={19}, journal={ADVANCED FUNCTIONAL MATERIALS}, publisher={Wiley}, author={Biswas, Manik Chandra and Chakraborty, Samit and Bhattacharjee, Abhishek and Mohammed, Zaheeruddin}, year={2021}, month={May} } @article{hossain_biswas_chanda_rubel_khan_hashizume_2021, title={A review on experimental and theoretical studies of perovskite barium zirconate proton conductors}, volume={7}, ISSN={["2522-574X"]}, DOI={10.1007/s42247-021-00230-5}, journal={EMERGENT MATERIALS}, author={Hossain, M.

In these devices, proton-conducting oxides (PCOs) are applied as electrolyte materials to transport protons. Excellent physical stability and higher proton transport number are two essential properties of electrolyte materials. Doped BaZrO3 (BZO) is a solid ion-conducting perovskite material with high chemical stability and good proton-conducting properties at an intermediate temperature range of 400–650 °C. Therefore, BZO is an attractive material among the exciting proton-conducting oxides as electrolyte material.

Bio-oil was produced by hydrothermal liquefaction (HTL) process using sweetgum hardwood, and utilized as a bio-based phenolic feedstock as an alternative for petroleum-based phenol in the synthesis of PF resin. Phenol was substituted with bio-oil (both as weight- and molar-based). The resulting PF resin was noted as BPF-W and BPF-M when bio-oil was used to replace 50% of phenol in weight- and molar-based, respectively, and then compared with neat PF resin in terms of free formaldehyde content, gel time, pH of the resin, solid content, bond strength and thermal stability. Results showed that BPF-M resin had less free formaldehyde content and longer gel time than BPF-W resin. No significant difference in pH and solid content was observed between bio-oil-based PF resins. Moreover, molar-based substitution resulted in a resin with higher bonding strength than that of weight-based substitution, and both BPF-W and BPF-M showed higher bonding strength then neat PF resin. TGA analysis of the resin revealed that substitution of phenol with bio-oil lowered the thermal stability of bio-oil derived PF resins.

In this research, we present the synthesis of nanoparticles from natural waste, renewable resources, such as eggshells and rice husk. The nanoparticles include in this study are: CaCO3 and Calcium hydroxyapatite (CHA) from eggshell and SiO2, from rice husk. Rice husk (RH and eggshells are excellent sources of bio based silica (SiO2), and calcium carbonate (CaCO3) particles respectively. About 45,000 tons of chicken eggshells are produced annually as a waste [1]. The safe disposal of these eggshells burdens the environment, poultry industry and consumers, financially. Therefore, alternative use of waste eggshell will be obviously a benefit to society. Recently we have developed a simple technique to extract CaCO3 from eggshell and used them as a value-added product [2-5]. Similarly the RH is a waste byproduct of rice and produces about 20-22 % weight of the total rice production. United States of America alone produced ~13 billion tons of rice in 2015 [6] and 10.6 million tons of sugar bagasse [7]. RH constitutes ~ 20% of silica by weight and usually used ineffectively.
