Taking lignosulfonate as a raw material, due to its molecular structure having more reactive groups, it is easy to form composite materials via a chemical oxidation reaction with an aniline monomer. After that, using a sodium lignosulfonate/polyaniline composite as the precursor, the activated high-temperature pyrolysis process is used to prepare porous carbon materials with controllable morphology, structure, oxygen, sulfur, and nitrogen content, which opens up a new way for the preparation of functional carbon materials.

LS/PANI composites were used as dye adsorbents for the removal of different cationic dyes (malachite green, methylene blue, and crystal violet). The adsorption behavior of LS/PANI composites as dye adsorbents for malachite green was investigated by examining the effects of the adsorbent dosage, solution pH, initial concentration of dye, adsorption time, and temperature on the adsorption properties of this dye.

Low-cost lignosulfonate (LS) doped with polyaniline (PANI) has been used as a precursor to produce porous carbon. LS has a highly dispersed and sparse microstructure and can be accidentally doped with S atoms.

Lignin is the only natural aromatic polymer and the second most abundant lignocellulosic resource in nature after cellulose, and its derived high-value products can be used in a variety of fields. An efficient, highly value-added and high-quality production of lignin is critical for lignocellulose biorefinery, but the complex and variable structure of lignin macromolecules, poor activity of reactions, and redundant functional groups make it difficult to prepare polymeric materials with stable properties. With the increasing research on lignin modification, the application of lignin composite hydrogels has also received great attention.

In this thesis, ligninsulfonate/polyaniline nanocomposites were synthesized by chemical oxidation using aniline as the monomer, lignin as the template and dopant, and ammonium persulfate as the oxidant. The results showed that the average diameter of the ligninsulfonate/polyaniline nanocomposite was 85 nm, and the composite electrode exhibited good electron conduction ability and excellent capacitive performance by ligninsulfonate doping.

In addition to the rich carbon content, the structure of lignin contains functional groups such as benzene rings, methoxyl groups, and phenolic hydroxyl groups. Lignin degradation has become one of the high value, high quality and high efficiency methods to convert lignin, which is of great significance to alleviating the current energy shortage and environmental crisis.

Due to population growth and dwindling fossil-fuel reserves, the demand for sugar and bio-ethanol requires significant improvement in sugarcane production.

Since most soft tissues of porpoises in the past were not preserved until now, the bone tissue is the only ideal material available. Here, 27 East Asian finless porpoise bone samples collected from Nantong, the East China Sea during two periods (1984-1992 and 2009) were used to explore the temporal variation of nine typical elements' concentration (Fe, Mn, Cu, Ni, Hg, Cr, Pb, As, and Cd, dry weight).

Material And Methods: In total, 845 consecutive patients with their first episode of spontaneous AUR associated with BPH were enrolled in this prospective randomized controlled trial. They were randomly assigned to be given either pharmacological treatment combined with bladder training or pharmacological treatment (tamsulosin 0.
Introduction And Hypothesis: We investigated the impact of diabetes mellitus (DM) on female lower urinary tract dysfunction.
Methods: We prospectively collected data of 1,640 consecutive diabetic women from the inpatient departments and outpatient clinics of urology, endocrinology, geriatrics, and nephrology in primary, secondary, and tertiary referral hospitals, rural healthcare stations, and nursing homes in Dujiangyan, China. Clinical histories were taken on an individualized basis depending on patient presentation.
