Considerable worldwide interest exists in discovering renewable energy sources that can substitute for fossil fuels. Lignocellulosic biomass, the most abundant and inexpensive feedstock on planet, has a great potential sustainable production of fuels, chemicals, carbon-based materials. Fast pyrolysis integrated with hydrotreating, one simplest, cost-effective, efficient processes to convert lignocellulosic biomass liquid hydrocarbon fuels transportation, attracted significant attention...
Abstract N6-methyladenosine (m 6 A) modification plays important roles in various cellular responses by regulating mRNA biology. However, how m A is involved innate immunity via affecting the translation of immune transcripts remains to be further investigated. Here we report that RNA methyltransferase Mettl3-mediated methylation promotes dendritic cell (DC) activation and function. Specific depletion Mettl3 DC resulted impaired phenotypic functional maturation DC, with decreased expression...
Abstract Although all‐inorganic perovskite solar cells (PSCs) demonstrate high thermal stability, cesium‐lead halide perovskites with iodine content suffer from poor stability of the black phase (α‐phase). In this study, it is demonstrated that incorporating InCl 3 into host lattice helps to inhibit formation yellow (δ‐phase) and thereby enhances long‐term ambient stability. The enhanced achieved by a strategy for structural reconstruction CsPbI 2 Br means 3+ Cl − codoping, which gives rise...
Abstract Ion migration as well electron transfer and coupling in resistive switching materials endow memristors with a physically tunable conductance to resemble synapses, neurons, their networks. Four different types of volatile another four nonvolatile are systemically surveyed terms the mechanisms electrical properties that basis computing applications. The memristor features spontaneous decay after cease electrical/optical stimulations, which closely related surface atom diffusion,...
Abstract Production of hydrocarbon fuel from biomass‐derived lignin sources with current vision biorefinery infrastructure would significantly improve the total carbon use in biomass and make conversion more economically viable. Thus, developing specialty commodity products derived‐lignin has been an important industrial scientific endeavor for several decades. However, deconstruction lignin's complex polymeric framework into low molecular weight reactive moieties amenable deoxygenation...
A New Lignin BioJet: Jet fuel-range hydrocarbons (C<sub>7</sub>–C<sub>18</sub>) can be produced directly from biomass-derived lignin by selective C–O–C bond cleavage and simultaneous hydrodeoxygenation using combinations of noble metal catalysts (Ru/Al<sub>2</sub>O<sub>3</sub>) acidic zeolites (H<sup>+</sup>-Y) in the aqueous phase.
Abstract The double perovskite Cs 2 AgBiBr 6 single crystal holds great potential for detecting applications because of its low minimum detectable dose rate and toxic‐free merit. Nevertheless, the disordered arrangement Ag + /Bi 3+ usually gives rise to unexpected structural distortion thereafter heavily influences photoelectric properties crystal. Herein, phenylethylamine bromide is demonstrated be capable in situ regulation order–disorder phase transition improved ordering extent...
Abstract Super Lewis acids containing the triflate anion [e.g., Hf(OTf) 4 , Ln(OTf) 3 In(OTf) Al(OTf) ] and noble metal catalysts (e.g., Ru/C, Ru/Al 2 O ) formed efficient catalytic systems to generate saturated hydrocarbons from lignin in high yields. In such systems, triflates mediated rapid ether bond cleavage through selective bonding etheric oxygens while catalyzed subsequent hydrodeoxygenation (HDO) reactions. Near theoretical yields of were produced model compounds by combined...

Biofuel or biochemical production from biomass, especially lignocellulosic is the most promising option to replace fossil-based products achieve sustainability. However, biomass currently under-utilized because conversion technologies have faced significant challenges compete with incumbent petroleum technologies. Advancement in catalysis plays a central role increasing readiness of In this respect, improving catalyst stability one well-known grand for catalysis, which impedes scaling up and...
Abstract Transforming polyolefin waste into liquid alkanes through tandem cracking‐alkylation reactions catalyzed by Lewis‐acid chlorides offers an efficient route for single‐step plastic upcycling. Lewis acids in dichloromethane establish a polar environment that stabilizes carbenium ion intermediates and catalyzes hydride transfer, enabling breaking of polyethylene C−C bonds forming alkylation. Here, we show selective deconstruction low‐density (LDPE) to is achieved with anhydrous aluminum...
