Microbial electrosynthesis (MES) for CO2 capture and utilization has been highlighted for carbon-negative intermediate chemical production. Interface engineering of the electrode surface promotes electron uptake by electroactive bacteria through extracellular electron transport systems and is essential for enhancing acetate production from CO2. This study developed a polyaniline (PANI) electrodeposited graphite felt (GF) electrode to enhance acetate production in MES. The high biocompatibility and electrical conductivity of PANI promoted biofilm formation by increasing the interfacial interaction of electroactive bacteria. The physicochemical properties of PANI/GF were analyzed by Eenergy dispersive X-ray spectroscopy, Fourier transform infrared spectrometry, Raman spectroscopy, and X-ray diffraction. PANI/GF produced higher acetate levels (61.8 g/m2cat/day) from CO2 than the unmodified GF (41.6 g/m2cat/day). The specific capacitance (Cp) of PANI/GF (0.018 Fg-1) was 8.7 times higher than that of the unmodified GF (0.002 Fg-1). The PANI/GF electrodes promoted biofilm formation on the surface and improved the enrichment time of MES. In conclusion, the PANI/GF-modified electrodes facilitate electroactive bacteria–electrode interactions and extracellular electron transfer to improve the performance of MES. © 2024, The Authors.

The development of the mylonite zone along the Median Tectonic Line (MTL), southwest Japan, which originated from the Cretaceous granitic rocks, was examined to understand strain localization during cooling. The E-W trending and north-dipping mylonitic rocks, which constitute the upper plate of the north dipping MTL, were derived from two different protoliths: protomylonitic tonalite and mylonitic granite distributed at a distance of c. 0–300 m and 300–700 m from the MTL, respectively. Microstructures and crystallographic preferred orientations (CPOs) of quartz and the two-feldspar thermometry were analyzed to infer the deformation conditions and their spatiotemporal development in the MTL mylonite zone. The mylonitic granite is further divided into southern and northern mylonite zones, which exhibit A- and B-type quartz microstructures formed by subgrain rotation and grain boundary migration recrystallization, respectively. The quartz c -axis CPOs dominantly show a medium-temperature Y -maximum pattern in mylonitic granite and protomylonitic tonalite, with some occurrences of a low temperature type-I crossed-girdle quartz c -axis CPO. The deformation of quartz originally occurred at medium temperatures of 435–490°C in the northern zone, forming mylonitic granite with a B-type quartz microstructure. As temperature decreased, the strain localized into the southern zone to form an A-type quartz microstructure at 355–435°C. The protomylonitic tonalite formed under similar temperature conditions. At temperatures below 355°C, ductile deformation ceased in most parts of granite and tonalite, and only occurred in a very narrow zone up to 50 m wide, forming ultramylonite in direct proximity to the MTL at the brittle–ductile transition conditions in quartz ( c. 300°C). The strain localization occurred not in a single shear zone but in each of the different strands of shear zones comprising the different protoliths. One of the strains developed into the crustal-scale shear zo

The synthesis of microwave-absorbing materials through a combined destruction process using mechanical alloying and ultrasonic vibration is significant due to its practical, waste-free scalability. Barium hexaferrite is the best candidate for synthesizing radar absorber materials through a combined destruction process. The substitution of Mg-Al on barium hexaferrite and decreasing particle size can increase the absorption of electromagnetic waves. Mixing stoichiometric precursors Sigma Aldrich 99 % BaCO3, Fe2O3, Al2O3, and MgO through wet milling for 20 h, followed by sintering at 1200 °C for 2 h to grow crystal embryos. Mechanical alloying was used to create the single-phase BaFe12-2xMgxAlxO19 (x = 0;0.3;0.5;0.7). re-milling for 20 h and ultrasonic vibration for 2 h reduced the particle size of the Mg-Al reinforced barium hexaferrite crystalline material. The increase in Mg-Al substitution in barium hexaferrite does not change the hexagonal structure but increases the density and absorption of electromagnetic waves. Mg-Al substitution at x = 0.3 resulted in uniform average particle size of 211.8 nm with a narrow particle size distribution, resulting in the lowest reflection loss of −17.62 dB at 8.2 GHz. This research increases the absorption ability of BaFe11.4Mg0.3Al0.3O19 electromagnetic waves up to 98 %. © 2022

A viscoplastic self-consistent (VPSC) numerical model for deformation texture prediction been developed and applied to the plane strain compression problems of the high temperature austenite steels having fcc lattice structure. Using the VPSC model, the parameter study of the strain rate sensitivity exponent (m-value) was conducted and the results were compared with those by an extended Taylor model (the viscoplastic constitutive law is employed while uniform strain assumption over grains in the representative volume element is adopted) and by the hot rolling experiments using Fe-70Ni fcc metal. Despite the small underestimation of brass texture, the results by VPSC model have revealed that m = 0.02 case successfully reproduced the similar texture with the experimental ones of 650 oC hot rolled Fe-70Ni sample, while m = 0.2 case reproduced 850 oC hot rolled sample texture. By contrast, the extended Taylor model overestimated the copper texture for any parameter cases. Therefore, the simulated deformation textures by the VPSC model agree better than those by the extended Taylor model. In addition, the effect of deformation magnitude on the texture formation has been analysed by using the VPSC model. The results find the more pronounced copper texture with increasing compressive strain, which agrees with the experimental results. ©2019 The Society of Materials Science, Japan

We fabricate an undoped Ge quantum well under a 30 nm relaxed Ge0.8Si0.2 shallow barrier. The bottom barrier contains Ge0.8Si0.2 (650 ℃) followed by Ge0.9Si0.1 (800 ℃) such that variation of Ge content forms a sharp interface that can suppress the threading dislocation density (TDD) penetrating into the undoped Ge quantum well. The Ge0.8Si0.2 barrier introduces enough in-plane parallel strain (Ε strain -0.41%) in the Ge quantum well. The heterostructure field-effect transistors with a shallow buried channel obtain an ultrahigh two-dimensional hole gas (2DHG) mobility over 2×106 cm2/Vs and a very low percolation of 5.625 × 1010cm−2. A tunable fractional quantum Hall effect at high densities and high magnetic fields has also been observed. This approach defines strained germanium as providing the material basis for tuning the spin-orbit coupling strength for fast and coherent quantum *** Codes 81-05, 81V70 © 2022, CC BY-NC-ND.

Environmental pollution poses a major hurdle to sustainable development, and harnessing solar energy for water treatment has emerged as a promising solution. In this study, flexible, macroporous photocatalytic membranes were developed by combining photocatalysis with membrane separation technology and hydrogen peroxide (H2O2), aiming to improve the degradation efficiency of tetracycline (TC). The g-C3N4/BaTiO3/PVDF photocatalytic membranes were fabricated using a phase inversion method, which successfully addressed challenges such as catalyst agglomeration and recovery difficulties, surpassing traditional membrane separation methods. Additionally, the g-C3N4/BaTiO3 photocatalyst exhibited excellent compatibility with PVDF. Under 120 min of xenon lamp irradiation, the membranes achieved a TC degradation efficiency of 90.63 %. These membranes also demonstrated remarkable permeability, and they maintained high stability and reusability after five degradation cycles, showcasing their promising potential for photocatalytic water treatment applications. © 2025 The Korean Society of Industrial and Engineering Chemistry

This study aims to analyze the incorporation of widely available, cheap and biobased waste material such as wood charcoal which is used as filler in natural fiber reinforced polymer composites. Jute woven fabric (1 × 1 plain weave) was used as a natural fiber reinforcement, unsaturated polyester resin was used as matrix material, and wood charcoal powder used as bio-filler to manufacture various composite material formulations of 25% fiber weight fraction. The wood charcoal filler loadings were 4, 8, 12, 16 and 20 wt% in the polymer matrix of the composites. The developed composite formulations were tested in terms of mechanical and physicochemical properties. Improved tensile properties were revealed with a 4 wt% filler modification, compared to the reference (unmodified) polymer composite. Nonetheless, further increase of filler (8–20 wt%), led to lower mechanical properties. Thermogravimetric analysis showed increased thermal stability of the 4 wt% charcoal filler modified composite compared to the reference one.
