High-performance Na-ion capacitor (NIC) was constructed with graphite recovered from spent Li-ion batteries (LIBs) as battery-type negative electrode and high-surface-area activated carbon as a supercapacitor component. Unlike Li-insertion into graphite, Na-insertion into graphite is extremely limited; hence, a "solvent-co-intercalation" mechanism was proposed for high reversibility using ether family solvents. First, the Na-insertion properties were assessed in the half-cell assembly with 0.5 m NaPF6 in tetraethylene glycol dimethyl ether as an electrolyte solution and compared with the commercial graphite. The NIC comprised pre-sodiated graphite as a negative electrode and commercial activated carbon as a cathode. This fascinating NIC configuration displayed the maximum energy density of 59.93 Wh kg-1 with exceptional cyclability of 5000 cycles at ambient temperature with approximately 98 % retention. Interestingly, the electrode aging process in the presence of electrolyte resulted in approximately 19 % higher energy density than the routine electrode heat treatment. Further, the electrochemical activity of the NIC at various temperatures was studied, and it was found that the graphite recovered from spent LIBs could be effectively reused towards the construction of high-performance charge storage devices with exceptional performance.In nursing practice, awareness of ethical inner values and a common understanding of nursing and caring are needed. It is therefore important to highlight ideas of caring in nursing practice. The aim of this paper was to illuminate nursing, caring and ethical inner values in caring and caring in nursing practice. By being attentive, open, respectful and treating the patient as a person, nurses can enhance both their own and the patient's sense of personal meaning in the caring relationship. Nurses can use self-reflection to create an awareness of nursing, caring and ethical inner values in caring.Internal biliary stenting during biliary reconstruction in liver transplantation decrease anastomotic biliary complications. Implantation of a resorbable internal biliary stent (RIBS) is interesting since it would avoid an ablation gesture. The objective of present work was to evaluate adequacy of selected PLA-b-PEG-b-PLA copolymers for RIBS aimed to secure biliary anastomose during healing and prevent complications, such as bile leak and stricture. The kinetics of degradation and mechanical properties of a RIBS prototype were evaluated with respect to the main bile duct stenting requirements in liver transplantation. For this purpose, RIBS degradation under biliary mimicking solution versus standard phosphate buffer control solution was discussed. Morphological changes, mass loss, water uptake, molecular weight, permeability, pH variations, and mechanical properties were examined over time. The permeability and mechanical properties were evaluated under simulated biliary conditions to explore the usefulness of a PLA-b-PEG-b-PLA RIBS to secure biliary anastomosis. Results showed no pH influence on the kinetics of degradation, with degradable RIBS remaining impermeable for at least 8 weeks, and keeping its mechanical properties for 10 weeks. Complete degradation is reached at 6 months. PLA-b-PEG-b-PLA RIBS have the required in vitro degradation characteristics to secure biliary anastomosis in liver transplantation and envision in vivo applications.In this study, high-performance countercurrent chromatography was employed to isolate six anthraquinone diglucosides, namely, cascarosides A-F, from cascara sagrada (Rhamnus purshiana DC [Rhamnaceae]) bark. The n-butanol-soluble extract of cascara sagrada was separated by off-line two-dimensional high-performance countercurrent chromatography. The first-dimensional high-performance countercurrent chromatography resolved the n-butanol-soluble extract (510 mg) of cascara sagrada using the flow-rate gradient method with a chloroform-methanol-isopropanol-water (6614, v/v/v/v, normal-phase mode) system to afford four anthraquinone diglucoside fractions (groups I [cascarosides C-D, 71 mg], II [cascarosides E-F, 56 mg], III [cascaroside A, 53 mg], and IV [cascaroside B, 31 mg]). Groups I and II were separated by the second-dimensional high-performance countercurrent chromatography using an ethyl acetate-n-butanol-water (7310, v/v/v, normal-phase mode) system to yield cascarosides C (34 mg), D (26 mg), E (19 mg), and F (15 mg). Additionally, one-step preparative-scale high-performance countercurrent chromatography method was developed to isolate large amounts of cascarosides A (389 mg) and B (187 mg) from the water-soluble extract (2.1 g) of cascara sagrada using an ethyl acetate-n-butanol-water (2810, v/v/v, normal-phase mode) system. The current study demonstrated that high-performance countercurrent chromatography is a powerful technique for the isolation of marker compounds from herbal materials.A luminescent EuIII coordination polymer with O2 -sensing units under air, EuIII -hcpt (hcpt 2,3,6,7,10,11-hexakis(4-carboxy-phenyl)triphenylene), is reported. read more The hexadentate carboxylic acids in hcpt ligands play an important role in the formation of tight-packed three-dimensional networks in EuIII -hcpt, giving hyper thermo-stable structures (decomposition temperature=420 °C). The three-dimensional porous network promotes bright luminescence (4f-4f emission quantum yield=70 %). The emission lifetime of EuIII -hcpt under vacuum (0.86 ms) was twice as large as that under O2 (0.48 ms, 1 atom101.3 kPa). The Arrhenius analysis of the emission decay profile indicates that the back energy transfer (BEnT) from the emitting level of the europium(III) ion to the excited T1 state of the hcpt ligand should be activated at room temperature. The gradual decrease of emission lifetime is caused by the BEnT process in EuIII -hcpt. Finally, an advanced pressure-sensitive luminophore is demonstrated. Gender differences in the efficacy of treatment and the mortality of HIV-infected patients have not yet been fully elucidated. For the first time, we used data from a 20-year cohort of people living with HIV (PLWH) in four provinces (Fars, Bushehr, Bandar Abbas, and Kohgiluyeh and Boyer-Ahmad) in the southern part of Iran to assess the gender difference in all-cause mortality in PLWH in Iran. We analysed data for 1216 patients aged ≥ 15years who were diagnosed with HIV/AIDS between 1997 and 2017. Three hundred and fourteen (25.8%) were women. The death rate from all causes among women was 13.7% vs. 43.8% among men (P<0.001). All-cause mortality was significantly associated with gender [the adjusted hazard ratio (aHR) for men compared with women was 3.20], not being on antiretroviral therapy (ART) compared with being on ART at the last visit (aHR5.42), older age (aHR1.03), delayed HIV diagnosis compared with early diagnosis (aHR1.72), history of incarceration (aHR1.57), higher log CD4 count at diagnosis (aHR0.
