Abstract

Laparoscopic liver resection (LLR) for hepatocellular carcinoma (HCC) remains controversial, especially for tumors larger than 5 cm. We compared the short- and long-term outcomes of laparoscopic and open liver resection (OLR) for large HCC.Patients with large HCC after curative hepatectomy were enrolled. To compare the short-term outcomes, propensity score matching (PSM) and inverse probability treatment weighting (IPTW) were performed to reduce the effect of confounding factors, respectively. Subsequently, Cox-regression analyses were conducted to identify the independent risk factors associated with decreased recurrence-free survival (RFS) and poor overall survival (OS).There were 265 patients enrolled in the final analysis: 146 who underwent OLR and 119 who underwent LLR. There was no significant difference between the OLR and LLR groups according to PSM and IPTW analysis (all P 0.05). Multivariable analysis revealed that LLR was not independently associated with poorer OS (HR 1.15, 95% CI 0.80-1.67, P = 0.448) or RFS (HR 1.22, 95% CI 0.88-1.70, P = 0.238).There were no significant differences in perioperative complications or long-term prognosis between LLR and OLR for large HCC, which provides evidence for standard laparoscopic surgical practice with adequate surgeon experience and careful patient selection.

19. Constructing and optimizing core–shell structured Co@TiO2 as highly efficient electromagnetic wave absorber

Abstract

To achieve highly efficient electromagnetic wave absorber, elaborately designing magnetic–dielectric Co@TiO2 microspheres with core–shell configuration are successfully constructed through a facile sequential process of liquid phase reduction–sol–gel–annealing. Owing to the core–shell configuration and the synergistic effect among magnetic and dielectric components, the annealed sample shows outstanding electromagnetic wave absorption (EMA) in X and Ku band. Impressively, a maximum reflection loss (RLmax) is reached –56.6 dB at a coating thickness of 2.3 mm with corresponding effective absorption bandwidth (EAB10) of 7.2 GHz (including 65% of Ku band and 82.5% of X band), much stronger than those of as-prepared Co (EAB10 of 1.6 GHz, RLmax of 14.6 dB) and pristine Co@TiO2 (EAB10 of 2.9 GHz, RLmax of 16.3 dB). An EAB10 covering completely the whole X and Ku band could be obtained by controlling the thickness only from 2.0 mm to 2.5 mm. The composites have both outstanding RL and wide EAB10 with the thin coating thickness, reinforcing that fabricating core–shell configuration composites is an efficient strategy to boost the EMA efficiency.

Abstract

Air-stable ambipolar organic field-effect transistors (OFETs) are fabricated from the active layers of π-conjugated polymer and elastomer composites. Compared to the p-channel dominant charge transport behavior of pure donor–acceptor-type copolymer semiconductors, the polymer composites exhibited superior ambipolar charge transport characteristics with well-balanced and high electron and hole mobilities, both of more than 1.0 cm2/Vs. Moreover, these OFETs exhibited significantly improved air stabilities, particularly in the n-channel regime, which is because the encapsulation effect of the nanofibril conjugated polymers surrounded by the elastomer matrix efficiently suppressed electron trapping. At the optimal composition, spinodal decomposition of the constituent polymers is induced, forming fibrillar network structures during the solution casting and thermal annealing processes. These anisotropic polymer aggregates embedded in the elastomer matrix are induced to align in a direction parallel to the channel by directional printing techniques, such as off-centered spin coating and bar coating. This strategy of controlling the semiconductor film morphology is beneficial for the fabrication of high-performance and air-stable complementary-like electronic circuits. Furthermore, the embedded nanofibril morphology in a deformable elastomer can be widely used to realize stretchable optoelectronic devices.

Abstract

This study investigates the vibration responses of external post-tensioned (PT) tendons based on experimental data. The vibration signals measured from four large-scale external post-tensioned tendon specimens subjected to localized corrosion until severe level of damage were accumulated. A series of impact tests was conducted to measure lateral vibration signals and the variation in the tension was continuously monitored using a load cell. The acquired vibration signals were evaluated using an axially-tensioned beam model in which the properties were varied to reflect the loss of tension and the reduction in the bending stiffness caused by corrosion damage. A comparison between the experimental data and the analytical results indicates that the natural frequencies were shifted as the residual tension decreased but were influenced by corresponding grout damage in a limited range. As a result, the frequency response was not appreciably affected by the damage level and the tension remained as the primary structural parameter of the external PT tendon with damage.

Abstract

To obtain soft electronics, it is essential to develop high-performance and mechanically flexible energy storage at the industry level. Herein, we report flexible high-energy-density lithium-sulfur (Li–S) batteries based on all-fibrous sulfur cathodes and separators. To implement free-standing and flexible sulfur cathodes, electrically conductive single-walled carbon nanotubes (CNTs) are impregnated with cellulose nanofibers. This fibrous structure forms a 3D porous electrode with a large surface area to improve redox kinetics and achieve a high sulfur loading content without the use of a metal collector, which can then be applied in high-energy-density batteries. These flexible sulfur cathodes are combined with a commercial glass fiber separator coated with a CNT layer through a cost-effective solution process to suppress the shuttle effects of lithium–polysulfide, thereby exhibiting robust cycling stability. The prepared Li–S batteries exhibit high capacities of 940 mAh g−1 at a charge current density of 1.57 mA cm−2 and at 25 °C, and the Coulombic efficiency exceeds 90% even after 50 charge/discharge cycles. Moreover, Li-S batteries with a high gravimetric energy density of 443 Wh kg−1 per cell is achieved, and these batteries demonstrate excellent reliability in regard to electrochemical performance even under severe mechanical stress conditions for over 100 cycles. Flexible and high-energy-density lithium-sulfur (Li-S) batteries based on all-fibrous sulfur cathodes and separators have structural uniqueness and chemical functionality, exhibit a high gravimetric energy density of 435 Wh kg−1 per cell and excellent reliability in terms of electrochemical performance with a slow decay rate of
