The demand for Li-ion batteries (LIBs) for vehicles is increasing. However, LIBs use valuable rare metals, such as Co and Li, aswell as environmentally toxic reagents. LIBs are also necessary to utilize for a long period and to recycle useful materials. The reduction, reuse,and recycle (3R) of spent LIBs is an important consideration in constructing a circular economy. In this paper, a flowsheet of the 3R of LIBs isproposed and methods to reduce the utilization of valuable rare metals and the amount of spent LIBs by remanufacturing used parts and designingnew batteries considering the concept of 3R are described. Next, several technological processes for the reuse and recycling of LIBs are *** technologies include discharge, sorting, crushing, binder removal, physical separation, and pyrometallurgical and hydrometallurgicalprocessing. Each process, as well as the related physical, chemical, and biological treatments, are discussed. Finally, the problem of developedtechnologies and future subjects for 3R of LIBs are described.

Objective: Skin damage induced by ischemia/reperfusion (I/R) is a multifactorial process that often occurs in plastic surgery. The mechanisms of I/R injury include hypoxia, inflammation, and oxidative damage. Hydrogen gas has been reported to alleviate cerebral I/R injury by acting as a free radical scavenger. Here, we assessed the protective effect of hydrogen-rich saline (HRS) on skin flap I/R injury. Methods: Abdominal skin flaps of rats were elevated and ischemia was induced for 3 h; subsequently, HRS or physiological saline was administered intraperitoneally 10 min before reperfusion. On postoperative Day 5, flap survival, blood perfusion, the accumulation of reactive oxygen species (ROS), and levels of cytokines were evaluated. Histological examinations were performed to assess inflammatory cell infiltration. Results: Skin flap survival and blood flow perfusion were improved by HRS relative to the controls. The production of malondialdehyde (MDA), an indicator of lipid peroxidation, was markedly reduced. A multiplex cytokine assay revealed that HRS reduced the elevation in the levels of inflammatory cytokines, chemokines and growth factors, with the exception of RANTES (regulated on activation, normal T-cell expressed and secreted) growth factor. HRS treatment also reduced inflammatory cell infiltration induced by I/R injury. Conclusions: Our findings suggest that HRS mitigates I/R injury by decreasing inflammation and, therefore, has the potential for application as a therapy for improving skin flap survival.

I do not know the meaning of 'disease without satisfactory treatment method', but I know the principle the doctor should obey when he faces such patients. That is he should choose the most effective method for the patients, considering not the interest of himself, but the benefit of the patients, not the treatment method he can offer, but the method the patients need. Unfortunately, such principles are not followed sometimes. Patients in plight are often manipulated by evil hand and then drop into despair circumstance. They become suspicious of every doctor in this field in the end. The development in this field is then blocked forever.

Efficient separation of palladium(Pd(Ⅱ))from high-level liquid waste(HLLW)not only helps the safe disposal of nuclear waste,but also is a vital importan supplement to Pd(Ⅱ)***,16 kinds of nove Amberlite XAD resins-based adsorbents were prepared by vacuum impregnation method for the separation of Pd(Ⅱ)from simulated HLLW,and the MMBT/XAD7HP prepared using 4-methyl-2-mercaptobenzothiazole(MMBT)as ligand and Amberlite XAD7HP resin(XAD7HP)as the carrier was selected as the optimal research *** analysis experiments proved the successful preparation of MMBT/XAD7HP,which exhibited ultrahigh adsorption selectivity for Pd(Ⅱ)(distribution coefficient(K_d)≥12584.5 ml·g^(-1),separation factor(SF_(Pd/M))≥2818.4)and superior adsorption capacity(Q≥130.1 mg·g^(-1)).The adsorption kinetics and adsorption isotherms for Pd(Ⅱ)matched with pseudo-secondorder(PSO)kinetics model and Langmuir model,indicating that the adsorption mode for Pd(Ⅱ)by MMBT/XAD7 HP was monolayer chemical *** dynamic column experiments showed that MMBT/XAD7 HP achieved efficiently separation of Pd(Ⅱ)from simulated HLLW,and the recovery rate was nearly 100% The adsorption mechanism was analyzed by Fourier transform infrared spectroscopy(FTIR),X-ray photoelectron spectroscopy(XPS)and density functional theory(DFT),and the ultrahigh selectivity of MMBT/XAD7 HP is attributed to the preferred affinity of the soft-N,S donor atoms in MMBT for Pd(Ⅱ).MMBT has the shortest frontline molecular orbital energy band gap(HOMO-LUMO)among the four ligands,which makes it easier to become an electron donor to attract Pd^(2+)to participate in ***_(3)^(-)participates in the adsorption to keep charge *** summary,MMBT/XAD7 HP has broad application prospects for the treatment of Pd(Ⅱ)in HLLW.

Aim: Keloids often occur on the chest wall, with high recurrence rates despite surgery and radiotherapy. Garment pressure therapy is commonly used to treat hypertrophic scars and keloids. Irregularity of the chest wall surface can inhibit the effects of the garment pressure therapy. This clinical study is to determine the effect of inflatable pressure garment in preventing keloid recurrence after keloid operation and radiotherapy. Methods: Chest wall keloid was removed and radiotherapy was administered at the surgical sites on the 1st and 7th postoperative days in 61 patients. An inflatable pressure garment device was designed and its pressure effect was confirmed by comparing it with the general pressure garment at the sites of the right and left infraclavicular area, manubrium and sternal area between breasts. The keloid patients were treated with inflatable pressure garment device 1 month after the operation. The clinical results were observed. Results: The detected pressures were 0.26 ± 0.21, 0.49 ± 0.16, 0.53 ± 0.10 and 0.91 ± 0.17 kPa at the sites of the right infraclavicular area, the manubrium area, the left infraclavicular area and sternal area between breasts with the general pressure garment. These were obvious lower (P < 0.05) than that generated with the inflatable pressure garment device of which the average pressures were 7.26 ± 0.41, 7.6 ± 0.32, 9.02 ± 0.54 and 10.31 ± 0.14 kPa at the corresponding ***-one patients were treated with this device after keloid surgical excision and radiotherapy. Satisfactory results were observed. Conclusion: Appropriate and effective pressure can be generated with inflatable pressure garment on the chest wall. This device may be useful in preventing chest wall keloid recurrence after keloid operation and radiotherapy.

For the recycling of Pd and Ag from high-level liquid waste(HLLW), the electrochemical behaviors of Pd and Ag in the simulated HNO_(3) solutions were investigated by cyclic voltammetry and potentiostatic *** electron microscopy(SEM) and X-ray diffraction(XRD) were used to-observe the deposits morphology and to evaluate their composition. The results indicate that the formation of NO_(2)^(-)electrodeposited. When Pd and Ag are electrodeposited together, more metals are gained in the same time, and the deposited Ag does not dissolve in this situation. The metals are electrodeposited completely at the potentials from -0.4 to -0.6 V(vs MSE) and the deposits contai-n Ag and PdHx. The electrodeposition of Pd can boost h-ydrogen evolution,and then the reaction between H;and NO_(2)^(-)is sped up, thereby lowering the concentration of NO_(2)^(-)and inhibiting the dissolution of Ag.
