    Thermal magnetoresistance from magnon scattering from a domain wall in an antiferromagnetic insulator

    We theoretically investigate magnon heat transport in an antiferromagnetic (AFM) insulator containing a domain wall (DW) in the presence of a magnetic field applied along the easy axis. We show that the intrinsic spin of the DW couples to the external magnetic field, which modifies the transmission of spin wave through the DW. Applying the magnetic field lifts the degeneracy between two AFM magnon modes and results in different occupation numbers for the two magnon modes. Combined with the finite reflection of a narrow domain wall, this is found to have a significant impact on the magnon heat transport, giving rise to thermal magnetoresistance. Our findings suggest that an AFM DW can be used as a controllable element for regulating the magnon heat current in magnonic devices through the application of a magnetic field.

    Effects of Framework Structures of Zeolite-Templated Carbons on Their Thermal Structural Transformations

    No full text
    Zeolite-templated carbons (ZTCs) are ordered microporous carbons synthesized by replicating the microporous structure of zeolites with carbon. Due to carbon growth within the confined spaces of zeolite micropores, ZTCs are composed of interconnected, buckybowl-like carbon moieties with abundant edge sites terminated by hydrogen (H) atoms. The amount of H-terminated edge sites and the local framework structure of ZTCs depend on their synthesis conditions. In this study, we investigated the effects of the initial framework structures of ZTCs on their thermal structural transformations. Our results demonstrate that ZTC frameworks primarily built with nanoribbon-like carbon moieties containing abundant H-terminated edge sites undergo significant dehydrogenation (removal of H2) and concomitant formation of new C-C bonds upon thermal treatment, leading to increased carbon surface curvature, reduced micropore diameter and volume, and enhanced ultramicroporosity. These structural changes also lead to substantial modifications in macroscopic properties, such as oxidative stability, work function, and ppb-level chloroform adsorption capability in water. The findings highlight the unique potential of synthesizing microporous carbons with tailored structures and physicochemical properties through post-synthesis thermal transformation of ZTCs.

    Metabolic engineering of Escherichia coli for enhanced production of p-coumaric acid via L-phenylalanine biosynthesis pathway

    No full text
    p-Coumaric acid (p-CA), an invaluable phytochemical, has novel bioactivities, including antiproliferative, anxiolytic, and neuroprotective effects, and is the main precursor of various flavonoids, such as caffeic acid, naringenin, and resveratrol. Herein, we report the engineering of Escherichia coli for de novo production of p-CA via the PAL-C4H pathway. As the base strain, we used the E. coli H-02 strain, which was previously engineered for sufficient supplementation of L-phenylalanine, the main precursor of p-CA. For the bioconversion of L-Phe to p-CA, we constructed and optimized an expression system for phenylalanine ammonia lyase (SmPAL), codon-optimized cinnamate 4-hydroxylase (AtC4H), and its redox partner, cytochrome P450 reductase (AtCPR1). We confirmed that the engineered cell showed higher production of p-CA at 30 degrees C and the addition of 0.5 mM 5-aminolevulinic acid could increase the production titer further. Subsequently, the main pathways of acetic acid (poxB and pta-ackA) were eliminated to reduce its accumulation and restore cell growth. Next, to increase the available pool of cofactor (NADPH), the co-expression system of the zwf gene in the pentose phosphate pathway (PPP) was integrated into genome and the expression level was optimized with synthetic promoters. Finally, by optimizing fed-batch culture in a 5 L-scale bioreactor, the engineered strain achieved 1.5 g/L p-CA with a productivity of 31.8 mg/L/h.
