By using the "bridge joint" effect of iron ions, cellulose nanocrystal-containing high-performance adsorbents were synthesized via coprecipitation method, which enhanced the cross-linking action of cellulose nanocrystal and polyethyleneimine. The morphology, specific surface area, surface chemistry and chemical valence of the adsorbents were characterized by SEM, FTIR, BET and XPS. According to the results, the iron ions successfully connect the two dispersed polymers together, inducing a large number of O-Fe-O bonds and, providing more adsorption active sites for the removal of seriously polluted and high-toxicity As(III)/As(V). Furthermore, the arsenic removal performance of the adsorbents was studied, and the adsorption mechanism was revealed according to the spectral characteristics of the chemical components. Of note, the synthesized iron-containing adsorbents are suitable for a wide pH range, which may offer a new application for nanocellulose in the treatment of arsenic pollution. The novel N-p-carboxy benzyl chitosan (CBC)/ poly (vinyl alcohol) (PVA) based mixed matrix membranes (MMMs) filled with surface-modified zeolite have been prepared using the dissolution casting technique. The applicability of prepared MMMs for direct methanol fuel cell (DMFC) was investigated in terms of water uptake, methanol permeation, and proton conductivity by changing filler content (10-50 wt. %). The zeolite was modified by silane coupling agent, 3-mercaptopropyltrimethoxysilane (MPTMS). The resultant modified zeolite (MZ) was incorporated into CBC/PVA blend to obtain mixed matrix PEMs. The functional group, structural properties, morphological and topographical investigation of MMMs were examined using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and Scanning electron microscopy (SEM) respectively. The prepared MMMs exhibited a remarkable decrease in methanol permeability of 2.3 × 10-7  cm2/s with C-CPMZ50. The maximum value of proton conductivity of 0.0527 Scm-1, was shown by C-CMPZ10. The prepared PEMs also displayed good stability during long term operating time. Hydroxyapatite-associated bacterial cellulose (BC/HA) is a promising composite for biomedical applications. However, this hybrid composite has some limitations due to its low in vivo degradability. The objective of this work was to oxidize BC and BC/HA composites for different time periods to produce 2,3 dialdehyde cellulose (DAC). The BC and oxidized BC (OxBC) membranes were mineralized to obtain the hybrid materials (BC/HA and OxBC/HA) and their physico-chemical, degradability, and bioactivity properties were studied. The results showed that OxBC/HA was more bioactive and degradable than BC/HA, which isa function of the degree of BC oxidation. see more High glucose levels in the BC degradation were observed as a function of oxidation degree, and other products, such as butyric acid and acetic acid resulted from DAC degradation. Therefore, this chemical modification reaction favors BC degradation, making it a good biodegradable and bioactive material with a potential for bone regeneration applications. The present work intends to study the variations in the rheological properties and aggregation behaviour of TEMPO-oxidised cellulose nanofibrils (CNF) aqueous suspensions, as a function of changes in concentration and systematic changes in the pH, by addition of acids with different anions. It was found that CNF suspensions form strong gels at mass fractions higher than 0.35 % and the gel point is ca. 0.18 %. On the other hand, aggregation is enhanced at acidic pH conditions due to lower charge repulsion among fibrils, leading to an increase of the suspension viscosity. However, distinct rheological behaviours were presented by CNF suspensions as different acids were applied. It was found that phosphate ions resulted in significant aggregation leading to formation of particles of large size and very strong gels, at pH 2.3; distinctly, the presence of acetate ions resulted in lower aggregation, lower particle size and weaker gels, at the same pH value. The collaborative endeavor in tissue engineering is to fabricate a bio-mimetic extracellular matrix to assist tissue regeneration. Thus, a novel injectable tissue scaffold was fabricated by exploring nanotailored hyaluronic acid (nHA) and methylcellulose (MC) (nHAMC) along with pristine HA based MC scaffold (HAMC). nHA with particle size ∼22 ± 5.3 nm were obtained and nHAMC displayed a honeycomb-like 3D microporous architecture. Nano-HA bestowed better gel strength, physico-rheological and biological properties than HA. It creditably reduced the high content of salt to reduce the gelation temperature of MC. The properties ameliorated with increased in-corporation of nano-HA. The addition of salt showed more prominent effect on gelation temperature of nHAMC than in HAMC; and salting-out effect was dependent on nHA/HA content. Biocompatible nHAMC assisted adequate cell adherence and proliferation with more extended protrusions with better migration rate than control. Thus, biomodulatory effect of nanotailored glycosaminoglycan could be asserted to design an efficient thermo-responsive scaffold. Biological functions of N-glycans are frequently related to their unique branching patterns. Multistage mass spectrometry (MSn) has become the primary method for glycan structural analysis. However, selection of the best fragment as the precursor for the next round of product-ion scanning is important but difficult. We have previously proposed the concept and designed the approach of glycan intelligent precursor selection (GIPS) to guide MSn experiments, but its use in N-glycans is not straightforward as some N-glycans are of high similarity in branching patterns. In the present work we introduced new elements to GIPS to improve its performance in N-glycan branching pattern analysis. These include a hypothesis and significance test, based on Bayes factor, and DPbiased as a new precursor selection strategy. The improved GIPS was successfully applied to identification of individual N-glycans, and incorporated into MALDI-MS N-glycan profiling for assignment of N-glycans obtained from glycoproteins and complex human serum.
