... Additives and biomass were co-combusted with sewage sludge (SS) to promote SS incineration treatment and energy generation. (Co-)combustion characteristics of sewage sludge (SS), water hyacinth (WH), and 5% five additives (K2CO3, Na2CO3, Mg2CO3, MgO and Al2O3) were quantified and compared using thermogravimetric-mass spectrometric (TG-MS) and numerical analyses. The combustion performance of SS de ...

Abstract:
... Cotton stalk was pretreated with 1-butyl-3-methyimidazolium chloride ([Bmim]Cl) and the effect of pretreatment factors, including liquid/solid ratio, temperature, and pretreatment duration on cotton stalk was investigated. Scanning electronic microscopy, Fourier transform infrared spectroscopy, and X-ray diffraction were used to identify structural changes in native and pretreated biomass. The opt ...

Abstract:
... 3,5-dinitrosalicylic acid (DNS) reducing sugar assay is the most convenient method for quantification of total reducing sugar in biomass hydrolysate, fermentation samples, sugar industry and biotechnology laboratories. The dimeric proton transfer salt 2-aminoethanaminium 2-(ethoxycarbonyl)-4,6-dinitrophenolate (AED) is an intensely colored derivative of DNS and in turn its reduced form intense col ...
... Wild growing mushrooms are traditional food items for man and also an important source of nutrients for small and big wildlife. Nevertheless, they can be species - specifically vulnerable for contamination with heavy metals and radionuclides. We studied a less known phenomenon of accumulation of highly toxic, the alpha-radiation emitter such as ²¹⁰Po and the beta emitter ²¹⁰Pb by three Leccinum mu ...

Abstract:
... The present paper describes novel low frequency (LF) ¹H NMR energy relaxation time signal analysis for mapping the different chemical and morphological domains in complex cattle manure (CM) and cattle forage (CF) biomass. Relaxation signals generated by different absorbed water pools and aliphatic chains are analyzed by specifically designed sparse representation methods and a convex optimization ...
... The identification of chemical impurities is crucial in elucidating the structures of biorefinery products using nuclear magnetic resonance (NMR) spectroscopic analysis. In the current biorefinery platform, contaminants derived from pretreatment solvents and decomposition byproducts may lead to misassignment of the NMR spectra of biorefinery products (e.g, lignin and bio-oils). Therefore, we inves ...
... The exploitation of renewable biomass resources toward green, high-value-added functional nanomaterials is promising. Bamboo is a “natural Si reservoir” that contains a considerable amount of silica. Available bamboo charcoal is the carbonated bamboo material with attractive features. Herein, 3D porous silicon is extracted from bamboo charcoal by simple calcination and magnesiothermic reduction. F ...
... The conservation of our element resources is a fundamental challenge of mankind. The development of alcohol refunctionalization reactions is a possible fossil carbon conservation strategy since alcohols can be obtained from indigestible and abundantly available biomass. The conservation of our rare noble metals, frequently used in key technologies such as catalysis, might be feasible by replacing ...
... The aims of this study were to boost growth attributes, yield, and nutrient uptake of rice in paddy fields using a combination of Bacillus pumilus strain TUAT-1 biofertilizer and different nitrogen (N) application rates in nursery boxes. Bacillus pumilus strain TUAT-1 was applied as an inoculant biofertilizer in conjunction with different rates of N fertilizer to rice seedlings in a nursery. Plant ...
... The temporal profiles of polycyclic aromatic compounds (PACs) in lake sediments reflect past changes in emissions, transport and deposition of these pollutants and, thus, record natural and anthropogenic processes. We document fluxes of PACs [(polycyclic aromatic hydrocarbons (PAHs), oxygenated PAHs (OPAHs) and azaarenes (AZAs)] deposited in two tropical high-altitude lakes in the Cajas National P ...
... In this research, corn stalk fibers (CSF) grafted polyacrylic acid (PAA) on their surfaces (CSF-g-PAA) were successfully prepared via heterogeneous esterification in the case of maintaining inherent fiber framework and shape. It can be used to removal cationic contaminants from aqueous solution. Four dyes and three metal ions were employed as models of cationic adsorbates to survey its adsorption ...
... 2-Pyrones have been identified as potential platform molecules derived from biomass to produce high-value chemicals. Theoretical studies utilizing density functional theory (DFT) simulations have shown the partially saturated form of these molecules undergoing a retro Diels–Alder (rDA) reaction in both vapor and solvent conditions. Developing an understanding of the effect of solvent media is cruc ...
... From the conventional use of biomass in the form of heating to the modern day use of biomass in the form of electricity generation and biofuel production, biomass has always been part of the evolution of mankind. Modern day use of biomass is gradually becoming more complex, and engineering played an important role in defining different directions. This review provides an overall view of biomass ut ...
... Listeria species are ubiquitous in nature and can adapt to survive in a variety of niches, including food processing environments. Listeria species that colonize these environments may also have the potential to persist. Food safety strategies designed to manage these niches include regular cleaning and disinfection with proven sanitizers containing biocide-active compounds. Typically, these sanit ...

Abstract:
... Three experiments were conducted to investigate the growth, survival, and standardized cohort biomass of Pacific bluefin tuna, Thunnus orientalis, larvae fed nutritionally enhanced prey during the first week of feeding using two commonly used, commercially available enrichment media, AlgaMac Enrich and Marine Glos. T. orientalis larvae exhibited exponential growth in standard length and dry weight ...
