Phenotypic and genotypic simultaneous advancement in parapatric ecotypes involving Senecio.
Realization of ethane-selective porous materials for efficient ethane/ethylene (C2H6/C2H4) separation is an important task in the petrochemical industry. Although a number of C2H6-selective adsorbents have been realized, their adsorption capacity and selectivity might be mostly dampened under humid conditions due to structure decomposition or co-adsorption of water vapor. A desired material should have simultaneously high C2H6 uptake and selectivity, excellent water stability, and ultralow water adsorption uptake for industrial applications, but such a material is elusive. Herein, we report a chemically stable hafnium-based material (Hf)DUT-52a, featuring the suitable pore apertures and less hydrophilicity for highly efficient C2H6/C2H4 separation under humid conditions. Gas sorption results reveal that (Hf)DUT-52a exhibits both high ethane adsorption capacity (4.02 mmol g-1) and C2H6/C2H4 selectivity (1.9) at 296 K and 1 bar, which are comparable to the majority of the top-performing materials. Most importantly, the less pore hydrophilicity enables (Hf)DUT-52a to exhibit a negligible water uptake of 0.036 g g-1 before 40% relative humidity (RH), effectively minimizing the impact of humidity on separation capacity. This material thus shows excellent separation capacity even under 40% RH with a high polymer-grade ethylene production capacity up to 8.43 L kg-1 at ambient conditions, as evidenced by the breakthrough experiments.Positron-emission tomography (PET) imaging enables cancer diagnosis at an early stage and to determine its pathological degree. However, tumor uptake efficiency of traditional PET radiotracers is usually low. Herein, we rationally designed a precursor CBT-NODA, the cold analogue CBT-NODA-Ga, and its corresponding radiotracer CBT-NODA-68Ga. Using these three compounds, we verified that coinjection of CBT-NODA-68Ga with CBT-NODA or CBT-NODA-Ga could lead to the synthesis of hybrid gallium-68 nanoparticles in furin-overexpressing cancer cells and enhance microPET tumor imaging in mice. In vivo experiments showed that coinjection of CBT-NODA-68Ga with CBT-NODA-Ga had the most prolonged retention of the radiotracer in blood, the highest radioactivity in tumor regions, and the most enhanced microPET tumor imaging in mice. We anticipate that, by combining the coinjection strategy with our CBT-Cys click condensation reaction, more radiotracers are developed for microPET imaging of more tumors in clinical settings in the future.Joints that connect thermoplastic polymer matrices (TPMs) and metals, which are obtained by comolding, are of growing importance in numerous applications. The overall performance of these constructs is strongly impacted by the TPM-metal interfacial strength, which can be tuned by tailoring the surface chemistry of the metal prior to the comolding process. In the present work, a model TPM-metal system consisting of poly(methyl methacrylate) (PMMA) and titanium is used to prepare comolded joints. The interfacial adhesion is quantified by wire pullout experiments. Pullout tests prior to and following surface modification are performed and analyzed. Unmodified wires show poor interfacial strength, with a work of adhesion (Ga) value of 3.8 J m-2. To enhance interfacial adhesion, a biomimetic polydopamine (PDA) layer is first deposited on titanium followed by a second layer of a poly(methyl methacrylate-co-methacrylic acid) (P(MMA-co-MAA)) copolymer prior to comolding. During processing, the MAA moieties of the copolymer thermally react with PDA, forming amide bonds, while MMA promotes the formation of secondary bonds and molecular interdigitation with the PMMA matrix. Control testing reveals that neither PDA nor the copolymer provides a substantial increase in adhesion. However, when used in combination, a significant increase in adhesion is detected. This observation indicates a pronounced synergistic effect between the two layers that strengthens the PMMA-titanium bonding. Enhanced adhesion is optimized by tuning the MMA-to-MAA ratio of the copolymer, which shows a maximum at a 24% MAA content and a greatly increased Ga value of 155 J m-2; this value corresponds to a 40-fold increase. Further growth in the Ga values at higher MAA contents is hindered by the thermal cross-linking of MAA; MAA contents above 24% restrict the formation of secondary bonds and molecular interdigitation with the PMMA chains. Our results provide new design principles to produce thermoplastic-metal comolded joints with strong interfaces.Alkaline zinc-based batteries are becoming promising candidates for green and economical energy-storage systems, thanks to their low cost and high energy density. The exploitation of the stable cathode materials with high rate capability and cycling stability is crucial for their further development. Herein, a series of NiSx coated with nitrogen-doped carbon (denoted as NiSx@NC) compounds (x = 0.5-1.0) are synthesized using the facile single-source precursor method. Benefiting from the unique phase-transitional NiSx@NC with high activity and enhanced conductivity from the well-balanced conductive metal nickel and carbon layer, the alkaline zinc-nickel batteries with a phase-transitional NiSx@NC cathode deliver a high capacity of 148 mA h g-1 at a high current density of 100 mA cm-2 and demonstrate a long lifespan of over 500 cycles with a high capacity retention of 98.8%.

Improved knowledge of in vivo function of the collateral ligaments is essential for enhancing rehabilitation and guiding surgical reconstruction as well as soft-tissue balancing in total knee arthroplasty. The aim of this study was to quantify in vivo elongation patterns of the collateral ligaments throughout complete cycles of functional activities.

Knee kinematics were measured using radiographic images captured with a mobile fluoroscope while healthy subjects performed level walking, downhill walking, and stair descent. The registered in vivo tibiofemoral kinematics were then used to drive subject-specific multibody knee models to track collateral ligament elongation.

The elongation patterns of the medial collateral ligament varied distinctly among its bundles, ranging from lengthening of the anterior fibers to shortening of the posterior bundle with increases in the knee flexion angle. The elongation patterns of the lateral collateral ligament varied considerably among subjects. It showed an average 4% shortening with increasing flexion until 60% to 70% of the gait cycle, and then recovered during the terminal-swing phase until reaching its reference length (defined at heel strike).
