In this paper, Co 9 S 8 nanoparticles embedded into amorphous carbon have been synthesized by a simple electrospinning method followed by a high-temperature annealing process. The unique structure endows the Co 9 S 8 /C composites with excellent electrochemical properties. Co 9 S 8 particles embedded into the carbon matrix show a high Li storage capacity around 1100 and 358 mAhg −1 at a current density of 0.1 and 5.0 Ag −1 , respectively. After 200 cycles, an impressive discharge capacity of around 1063.4 mAhg −1 can be obtained at a current density of 0.3 Ag −1 .
Compared with the common electrospun nanofibers, the alignment of the nanofibers exhibits interesting anisotropic mechanical properties and structural stability.
AIM:To compare neuroendoscopy versus minimal puncture drainage for surgical treatment of supratentorial hypertensive intracerebral hemorrhage.MATERIAL and METHODS: A total of 108 cases involving supratentorial intracerebral hemorrhage were retrospectively analyzed. In 30 cases, endoscopic surgery was performed, while 78 cases involved puncture surgery. We compared hematoma clearance rate, postoperative rebleeding rate, incidence of postoperative complications, operation duration, and Glasgow coma score seven days after surgery. Clinical data such as early postoperative rehabilitation time, Glasgow outcome score three months after surgery, and intensive care unit (ICU) stay were also compared between the two groups.
RESULTS:The results showed that endoscopic surgery was associated with a superior clinical therapeutic effect in hematoma clearance rates, GCS scores on postoperative day 7, the average ICU stay, early postoperative rehabilitation time and intracranial infection outcomes than minimal puncture drainage surgery for the treatment of supratentorial intracerebral hemorrhage (p<0.05). Three months after surgery, the favorable prognosis rate in the endoscopic treatment group was significantly higher than that in the craniotomy group [83.3% (28/34) vs. 61.5% (31/51), respectively; χ 2 =4.698, p=0.030]. In contrast, no significant differences in rebleeding, pulmonary infection, tracheotomy, secondary epilepsy, gastrointestinal hemorrhage, death in late postoperative period, or in baseline parameters were observed between the two groups (p>0.05).
CONCLUSION:Endoscopic surgery potentially represents a beneficial surgical procedure for treatment of supratentorial spontaneous intracerebral hemorrhage.
Natural sepiolite is widely used as an inorganic template to prepare functional nanomaterials. Herein, raw sepiolite and ultrafine TiO2 nanocrystals–decorated sepiolite nanofibers are fabricated by a hydrothermal reaction followed by an annealing process. For Li‐storage, the TiO2/sepiolite composites exhibit higher specific capacity and a longer lifespan than raw sepiolite. At a current density of 0.3 A g−1, the optimized TiO2/sepiolite composites deliver a discharge capacity of 1811 and 618 mAh g−1 at 1st and 300th cycle, respectively. In addition, the composites show a very stable specific capacity of 100 mAh g−1 at a current density of 0.1 A g−1 for Na‐storage up to 100 cycles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
