Lithium/fluorinated-carbon（Li/CFx） primary batteries are widely used in defense and military fields due to their stable discharge plateau, low self-discharge rate, and adaptability across a wide temperature range. However, enhancing their overall energy density and discharge capacity at low temperatures remains a critical challenge. Herein, we report a strategically designed LiBF4-based sulfite/carboxylate electrolyte, where the anion-involved solvation structure significantly enhances electrochemical kinetics by reducing the desolvation barrier. simultaneously, it introduces a radical reaction mechanism that contributes to additional capacity. As a result, the Li/CFxprimary batteries with this formulated electrolyte deliver a specific capacity of 2,257.15 mAh g-1at 25 °C. More importantly, when operating at -40 °C, the batteries exhibit an exceptionally high discharge capacity of 1,549.4 m Ah g-1and an energy density of 2,868.6 Wh kg-1. Even at -60 °C, the Li/CFxcells achieve a specific capacity of 444.3 mAh g-1and an energy density of 821.8 Wh kg-1at 0.1 C, significantly outperforming previously reported organic-based liquid electrolytes. This work offers a viable strategy for enhancing the specific capacity and energy density of primary batteries in extreme environments, providing valuable insights for future developments.

Is there a place for serum laminin determination in patients with liver disease and cancer?

World Journal of Gastroenterology 2008年第23期14卷 3628-3632页

Laminin is a glycoprotein which has an important role in the mechanism of fibrogenesis and is,thus,related to hepatic fibrosis in addition to presenting increased levels in several types of neoplasias. However,its determination is not routinely considered in the study of hepatic fibrosis. In this review,the authors critically comment on the role of this glycoprotein compared to other markers of fibrosis through non-invasive procedures(Fibroscan). They also consider its clinical investigational potential and believe that the continuation of these investigations might contribute to a better understanding of the fibrogenic mechanism,which could in turn either lead to the identification of patients at risk of developing fibrosis non-alcoholic fatty liver disease(NAFLD) and non-alcoholic steatohepatitis(NAsH) or at least be used as an indicator for hepatic biopsy in such patients. Finally,the authors believe that serum laminin determination might contribute to the diagnosis of epithelial tumor metastasis and peritoneal carcinomatosis.

Dynamic and ballistic impact behavior of biocomposite armors made of HDPE reinforced with chonta palm wood(Bactris gasipaes) microparticles

引用

Defence Technology（防务技术） 2018年第3期14卷 238-249页

作者： edison E.Haro Jerzy A.szpunar Akindele G.Odeshi Department of Mechanical Engineering University of Saskatchewan

The mechanical behavior of chonta palm wood(Bactris gasipaes) microparticles reinforced high density polyethylene(HDPE) under high strain-rate compressive and ballistic impact loading were *** palm wood microparticles were introduced into the HDPE via an extrusion process using parallel twin screw extruder to produce biocomposite containing 10, 20, 25, and 30 wt % chonta wood microparticles. In addition to mechanical tests, fractographic analysis was done to understand the failure mechanism in the biocomposites under dynamic and ballistic impact loads. The results indicate that both quasi-static and dynamic mechanical properties of HDPE are enhanced by reinforcement with chonta palm wood particles. The biocomposites containing 25 wt % wood microparticles exhibited the highest strength, stiffness, ballistic impact resistance and impact energy absorption capability. Introduction of microparticles of chonta palm wood as reinforcement into a polymeric matrix such as HDPE is therefore a promising method to develop biocomposites with enhanced capacity to withstand dynamic impact loading and absorb impact energy.
