Chemical reductions of lignin are useful to remove oxygen and create product slates that can function as renewable platform molecules for new fuels chemicals. Catalytic transfer hydrogenolysis (CTH) is an underexplored method reduce obviates the use dangerous nonrenewable hydrogen gas. While noble metals used extensively catalysts hydrogenation, sustainability remains a major challenge their deployment. In this work, we synthesized mixed-metal oxides earth-abundant Co Ni characterized using...
In this work, yellow pine (YP, softwood) and switchgrass (SG, grass) lignins were extracted as a coproduct of an organosolv γ-valerolactone (GVL) biorefinery that also produces biofuels furfural. The converted to carbon precursors for synthesizing porous activated electrodes high energy-density supercapacitors. This research details the impact lignin composition on derived structures electrochemical properties carbons. Lignin with various syringyl (S) guaiacyl (G) contents characterized...
Pretreatment and fractionation technologies have been used to separate isolate biomass polymers for conversion into fuels, chemicals, other products. A great deal of work has focused on dialing in reaction conditions (e.g., time, temperature, acid concentration, etc.) that are amenable isolating an uncondensed lignin product could be converted high value aromatic platform molecules. severity emerged as a term combines concentration single can compare various pretreatment technologies....
Abstract Phytosanitary treatments for logs and barked wood products are needed to mitigate the spread of thousand cankers disease through movement these commodities. The threatens eastern black walnut (Juglans nigra L.) populations in United States. It is caused by repeated attacks twig beetle (Pityophthorus juglandis Blackman) subsequent canker development fungal pathogen Geosmithia morbida M. Kolařík et al. Methyl bromide (MB) fumigations were evaluated efficacy against P. G. J. bolts....
Abstract Methyl bromide (MB) fumigation of oak ( Quercus sp.) logs destined for export is required to mitigate risks associated with movement the wilt fungus, Bretziella fagacearum . Alternative fumigants efficacy against B. are needed because MB's ozone-depleting properties. Fumigation sulfuryl fluoride (SF) considered a promising substitute. Logs (1.8 m long) were obtained from trees (18.3 29.2 cm diameter at breast height) that naturally infested (NI) or artificially inoculated (AI)...

This work uses a one-step KOH activation for lignin precursors to produce ultra-high mesoporous activated carbons (ACs) with an unprecedented combination of the surface area 3,207 m2 g-1 and mesopore ratio 76%. The produced ACs are applied supercapacitors (SCs) as well methylene blue (MB) adsorption. capacitance SCs in three-electrode system reaches 812.3 F it also demonstrates outstanding maximum MB adsorption capacity 1,250 mg g-1. By modifying process conditions, could be controlled from...
Abstract The phaseout of methyl bromide (MB) fumigation creates an urgent need for alternative phytosanitary treatment to limit the risk international spread oak wilt fungus, Bretziella fagacearum . Fumigation with ethanedinitrile (EDN) is considered a potential MB eradicate wood-inhabiting pests and pathogens. We evaluated efficacy EDN by comparing rate B. isolation before after red ( Quercus rubra or ellipsoidalis ) log sections from wilt–affected trees. Logs (range 15.2 98.0 cm long;...
