The unavoidable dendrite growth and shuttle effect have long been stranglehold challenges limiting the safety and practicality of lithium-sulfur ***,we propose a dual-action strategy to address the lithium dendrite issue in stages by constructing a multifunctional surface-negatively-charged nanodiamond layer with high ductility and robust puncture resistance on polypropylene （PP） *** uniformly loaded compact negative layer can not only significantly enhance electron transmission efficiency and promote uniform lithium deposition,but also reduce the formation of dendrite during early deposition *** importantly,under the strong puncture stress encountered during the deterioration of lithium dendrite growth under limiting current,the high ductility and robust puncture resistance（145.88 MPa） of as-obtained nanodiamond layer can effectively prevent short circuits caused by unavoidable lithium *** Li||Li symmetrical cells assembled with nanodiamond layer modified PP demonstrated a stable cycle of over 1000 h at 2 mA cm-2with a polarization voltage of only 29.3 ***,the negative charged layer serves as a physical barrier blocking lithium polysulfide ions,effectively mitigating capacity *** improved cells achieved a capacity decay of only 0.042%per cycle after 700 cycles at 3 C,demonstrating effective suppression of dendrite growth and capacity attenuation,showing promising prospect.

How to reduce flow resistance of nano-confined fluids to achieve a high flux is a new challenge for modern chemical engineering applications, such as membrane separation and nanofluidic devices. Traditional models are inapplicable to explain the significant differences in the flow resistance of different liquid–solid *** the other hand, friction reduction in liquid nano-lubrication has received considerable attention during the past decades. Both fields are exposed to a common scientific issue regarding friction reduction during liquid–solid relative motion at nanoscale. A promising approach to control the flow resistance of nano-confined fluids is to reference the factors affecting liquid nano-lubrication. In this review, two concepts of the friction coefficient derived from fluid flow and tribology were discussed to reveal their intrinsic relations. Recent progress on low or ultra-low friction coefficients in liquid nano-lubrication was summarized based on two situations. Finally, a new strategy was introduced to study the friction coefficient based on analyzing the intermolecular interactions through an atomic force microscope(AFM), which is a cutting-point to build a new model to study flowresistance at nanoscale.

Bio-oil is a new liquid fuel but very acidic. In this study, bio-oil pyrolyzed from rice husk and two bio-oil/diesel emulsions with bio-oil concentrations of 10 wt% and 30 wt% were prepared. Tests were carried out to determine their corrosion properties to four metals of aluminum, brass, mild steel and stainless steel at different temperatures. Weight loss of the metals immersed in the oil samples was recorded. The chemical states of the elements on metal surface were analyzed by X-ray photoelectron spectroscopy (XPS). The results indicated that mild steel was the least resistant to corrosion, followed by aluminum, while brass exhibited slight weight loss. The weight loss rates would be greatly enhanced at elevated temperatures. Stainless steel was not affected under any conditions. After corrosion, increased organic deposits were formed on aluminum and brass, but not on stainless steel. Mild steel was covered with many loosely attached corrosion materials which were easy to be removed by washing and wiping. Significant metal loss was detected on surface of aluminum and mild steel. Zinc was etched away from brass surface, while metallic copper was oxidized to Cu2O. Increased Cr2O3 and NiO were presented on surface of stainless steel to form a compact passive protection film. The two emulsions were less corrosive than the bio-oil. This was due to the protection effect of diesel. Diesel was the continuous phase in the emulsions and thus could limit the contact area between bio-oil and metals.

Gradient-porous copper foam electrodes were applied to alleviate the adverse effects of the uneven current distribution of electrodes along the electrolyte flow direction in thermally regenerative ammonia-based batteries(TRABs).The results indicated that gradient-porous copper foam with a decreasing pore size(TRAB-LMS)provided the most uniform current distribution and generated the highest power density(15.5 W/m^(2)),total charge(1800 C)and energy density(1224 W h/m^(3)).With the increase in flow rate,the power density of the TRAB-LMS increased considerably within a certain range and then decreased slightly,with the optimal flowrate at 15 mL/*** the optimal flow rate,the performance of TRAB-LMS increased when the ammonia concentration rose from 0.5 to 2 M(1 M=1 mol L^(-1));however,it decreased slightly when the ammonia concentration further increased to 3 *** slight decrease in the cathode potential suggested that the flow and ammonia concentration beyond the optional values facilitated not only the transfer of ammonia into the porous anode,but also the crossover of ammonia from the anode to the cathode.

Primary leiomyosarcoma of the inferior vena cava(IVC)is a rare disease,accounting for 0.5%of soft tissue sarcomas in adults[1].A diversity of therapeutic methods have been applied to treat this type of *** average survival time of patients who are not treated is merely 3-4 months[2].The effect of radiotherapy and chemotherapy remains unclear and controversial[3].On the other hand,the en-bloc resection with negative margins may be the only potentially curative treatment and therefore,can contribute to the long-term survival of the patients[4].During the operation,a reconstruction graft for the defected IVC needs to be chosen[5]as the graft-related complications are the surgeons’major concern,which include graft thrombosis and infection[6].Growing evidence has suggested that an allogeneic vein from donation after brain death or cardiac death is a better choice to avoid these complications[7].An allogeneic vein has been reported to be safely used in patients with pancreatic cancer in case of the portal vein and/or superior mesenteric vein invasion[8].A cryopreserved allograft can even be applied in the management of native and prosthetic aortic infections[7].Herein,we present a case of resection of a retrohepatic leiomyosarcoma of the IVC combined with partial caudate lobectomy and reconstruction with an allogeneic vein.
