Intestinal flora promotes the pathogenesis of colorectal cancer (CRC) through microorganisms and their metabolites. This study aimed to investigate composition intestinal in different stages CRC progression effect fecal microbiota transplantation (FMT) on mice. The microbiome from healthy volunteers (HC), adenoma (CRA), inflammatory bowel disease (IBD), patients were analyzed by 16s rRNA gene sequencing. In an azoxymethane (AOM)/dextran-sulfate-sodium (DSS)-induced mouse, FMT HC, CRA, CRC,...

In this study, a novel medium-heavy alloy (MHA) of 56Ni-38 W-5Co-1Ta was prepared using conventional casting and forging methods. This NiW exhibits unique combination medium density, high strength ductility under quasi-static loading conditions. the dynamic mechanical behaviors deformation mechanisms were systematically investigated. The exhibited that yield increase form ~1.6 GPa (1 × 10−3 s−1) to ~2.0 (3 103 owing formation accumulation nano-sized twinning at condition. Although twin...

To study the compressive mechanical properties and failure modes of TC11 titanium alloy fabricated by wire arc additive manufacturing (WAAM) technology in a large strain rate range at room temperature, quasi-static dynamic compression tests were carried out. In addition, optical microscopy (OM) scanning electron (SEM) employed to observe metallographic structure fracture morphology, respectively. The stress-strain curves 0.001 s-1-4000 s-1, original post-deformation microstructures,...

Twistronics, the manipulation of Moir\'e superlattices via twisting two layers two-dimensional (2D) materials to control diverse and nontrivial properties, has recently revolutionized condensed matter physics. Here, we introduce principles twistronics spin photonics, coining this emerging field spintwistronics. In spintwistronics, instead 2D materials, consist photonic topological lattices on a surface plasmonic polariton (SPP) platform. Each SPP wave supports construction formed by spins...

Ni-W medium heavy alloy has unique combination of high density, better quasi-static and dynamic plastic deformation ability. Its mechanical behaviors mechanisms at room temperature were investigated by employing split Hopkinson tensile bar system. Under extreme loading conditions, the exhibits yield strength, which is intimately related to twinning accumulation. However, an obvious ductility loss also observed in even with strong strain hardening capability. Generally, plasticity fracture...
