Summary: Naturally derived biopolymers have attracted great interest for constructing photonic materials with multi-scale ordering and other attractive properties. However, traditional processing often leads to non-uniform organization. In this study, researchers report a uniform biophotonic organization of cellulose nanocrystals decorated with superparamagnetic nanoparticles, resulting in a transformation from one phase to another with near-perfect orientation order parameter. The resulting films are flexible, robust, and possess anisotropic birefringence and light scattering, making them highly suitable for actuation in response to various stimuli.

Summary: Bamboo pulp was used to produce modified cellulose nanofiber (M-CNF) through ball milling. The structural changes of bamboo cellulose with different degrees of substitution (DS) were examined using FTIR, XRD, TEM, AFM, and elemental analysis. The DS reached 0.88 after just 2 hours of ball milling, while the diameter of M-CNF was 2 to 3 nm after just 1 hour of ball milling. The modified nanocellulose exhibited hydrophobicity, with a water contact angle of 87 degrees. Nanopaper made from the nanocellulose by vacuum filtration was highly transparent, with an optical transmittance of 88.8% at 550 nm. However, the transmittance of the modified nanopaper decreased to almost 0 in the wavelength range of 200 to 300 nm. This nanopaper can be utilized as a flexible optoelectronic material, packaging material, or UV shielding material.

Summary: Polymer-enhanced ultrafiltration (PEUF) technique using quaternized hydroxyethyl cellulose ethoxylate (QHECE) as extracting agent was employed to remove chromium ions (Cr(VI)) from water. The retention efficiency reached 92% at pH 9.0 with a polymer mass of 50 mg, a pressure of 2.0 bar, an initial Cr(VI) concentration of 30 mg L-1, and a 10-kDa regenerated cellulose membrane. Increase in the Cr(VI):interferent molar ratio led to a decrease in retention efficiency, especially for higher sulfonate ion to Cr(VI) ratio. The maximum retention capacity of the polymer was found to be 299.46 mg g-1, and it could be reused for up to four consecutive sorption-desorption cycles.

Summary: New mixed-matrix ultrafiltration membranes (MMMs) consisting of polyethersulfone (PES) and microcrystalline cellulose (MCC) were developed for bromate (BrO3-) remediation from water using a nonsolvent induced phase separation (NIPS) method. The addition of MCC improved the hydrophilicity, water flux, and adsorption performance of the PES membranes. The MCC-integrated PES membranes exhibited enhanced antifouling properties and superior removal efficiency for bromate ions compared to the virgin PES membrane.

Summary: Phase pure SnS and SnS2 were synthesized and characterized using various physio-chemical techniques. The electrochemical properties of SnS and SnS2 as anode materials for lithium-ion batteries were investigated. SnS2 electrodes showed superior cycling performance compared to SnS electrodes due to the production of more Li2S during the conversion reaction and the finer distribution of Li2S within the electroactive material.

Summary: The long-term drag reduction capability of poly(ethylene oxide) with a nominal molar weight of M-w = 4 x 10(6 )g/mol dissolved in water was investigated. It was found that the drag reduction capability decreased to 75% of the initial value when the molar weight of the polymer was approximately 5 x 10(5) g/mol. This decrease was attributed to mechanical degradation in the turbulent flow and aging of the polymer dissolved in water. A statistical model was used to describe the degradation process.

Summary: Nanofibrillated cellulose (NFC) has important applications in composites, water filters, and emulsifiers. The water affinity of NFC is a challenge as it negatively affects its integrity. Anaerobic digestion of biomass allows for the concentration of lignin in fermentation residue, from which nanolignocellulose fibers (LCNF) can be extracted. LCNFs with lignin contents between 23% and 29% were obtained from horse manure biogas production. Nanopapers made from LCNFs exhibited high tensile strengths and moduli, with decreased water absorption capacity due to increased lignin content.

Summary: PEKK is a semicrystalline high-performance polymer that has exceptional mechanical properties and a high continuous operation temperature, and is insoluble in most common solvents. Porous PEKK, desired for biomedical applications, is produced by a high-temperature thermally induced phase separation process using PEKK solutions in two high boiling aprotic solvents, 4-phenylphenol and 9-fluorenone. The choice of solvent has a significant influence on the phase separation behavior, foam morphology, and physical and mechanical properties of PEKK foams. Porous PEKK with porosities ranging from 70% to 90%, specific surface areas up to 194 m(2) g(-1), and elastic moduli ranging from 35 to 100 MPa are produced.

Summary: An amphiphilic macrosurfactant copolymer poly(acrylamide-co-styrene) was synthesized via micellar polymerization, which can produce stable toluene or cyclohexane-in-water high or medium internal phase emulsion (H/MIPEs) at concentrations as low as 0.1 wt %. Emulsion templates containing 2-hydroxyethyl methacrylate (HEMA) and N,N-methylenebis(acrylamide) (MBAm) can be polymerized to produce macroporous poly(HEMA-co-MBAm)M/HIPEs. The poly(HEMA-co-MBAm)M/HIPEs stabilized with lower emulsifier content showed higher mechanical stability in dry and swollen state compared to poly(HEMA-co-MBAm)HIPEs reported in literature.

Summary: Inverse Gas Chromatography (IGC) is an important technique for characterizing solids. It determines the specific retention volume of the probe molecule, which is the basis for analyzing various physico-chemical properties. Two equations have been used in the literature to calculate the retention volume, but one of them is thermodynamically incorrect. This study shows that the specific retention volume strongly depends on column temperature, and normalizing it to 0 degrees C can lead to significant overestimation of heats of sorption.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
