Lithium recovery from end-of-life Li-ion batteries(LIBs)through pyro-and hydrometallurgical recycling processes involves several refining stages,with high consumption of reagents and energy.A competitive technological alternative is the electrochemical oxidation of the cathode materials,whereby lithium can be deintercalated and transferred to an electrolyte solution without the aid of chemical extracting *** article investigates the potential to selectively recover Li from LIB cathode materials by direct electrochemical extraction in aqueous *** process allowed to recovering up to 98%of Li from high-purity commercial cathode materials(LiMn_(2)O_(4),LiCoO_(2),and Li Ni_(1/3)Mn_(1/3)Co_(1/3)O_(2))with a faradaic efficiency of 98%and negligible co-extraction of Co,Ni,and *** process was then applied to recover Li from the real waste LIBs black mass obtained by the physical treatment of electric vehicle battery *** black mass contained graphite,conductive carbon,and metal impurities from current collectors and steel cases,which significantly influenced the evolution and performances of Li electrochemical ***,due to concomitant oxidation of impurities,lithium extraction yields and faradaic efficiencies were lower than those obtained with high-purity cathode *** oxidation was found to occur within the voltage range investigated,but it could not quantitatively explain the reduced Li extraction *** fact,a detailed investigation revealed that above 1.3 V ***/Ag Cl,conductive carbon can be oxidized,contributing to the decreased Li *** on the reported experimental results,guidelines were provided that quantitatively enable the extraction of Li from the black mass,while preventing the simultaneous oxidation of impurities and,consequently,reducing the energy consumption of the proposed Li recovery method.

Endoscopic ultrasound and magnetic resonance imaging for re-staging rectal cancer after radiotherapy

AIM： To compare the sensitivity and specificity of two imaging techniques, endoscopic ultrasound （EUS） and magnetic resonance imaging （MRI）, in patients with rectal cancer after neoadjuvant chemoradiation therapy. And we compared EUS and MRI data with histological findings from surgical specimens. METHODS： Thirty-nine consecutive patients （51.3% Male; mean age： 68.2 ＋ 8.9 years） with histologically confirmed distal rectal cancer were examined for staging. All patients underwent EUS and MRI imaging before and after neoadjuvant chemoradiation therapy. RESULTS： After neoadjuvant chemoradiation, EUS and MRI correctly classified 46% （18/39） and 44% （17/39） of patients, respectively, in line with their histological T stage （P 〉 0.05）. These proportions were higher for both techniques when nodal involvement was considered： 69% （27/39） and 62% （24/39）. When patients were sorted into T and N subgroups, the diagnostic accuracy of EUS was better than MRI for patients with T0-T2 （44% vs 33%, P 〉 0.05） and NO disease （87% vs 52%, P = 0.013）. However, MRI was more accurate than EUS in T and N staging for patients with more advanced disease after radiotherapy, though these differences did not reach statistical significance. CONCLUSION： EUS and MRI are accurate imaging techniques for staging rectal cancer, However, after neoadjuvant RT-CT, the role of both methods in the assessment of residual rectal tumors remains uncertain.

Light emitting devices based on Si nanoclusters:the integration with a photonic crystal and electroluminescence properties

STMicroelectronics MLD R&Dstradale Primosole 5095121 Catania Italy.

We present the properties and potentialities of light emitting devices based on amorphous Si nanoclusters. Amorphousnanostructures may constitute an interesting alternative to Si nanocrystals for the monolithic integration of optical andelectrical functions in Si technology. In fact, they exhibit an intense room temperature electroluminescence (EL). The ELproperties of these devices have been studied as a function of current and of temperature. Moreover, to improve theextraction efficiency of the light, we have integrated the emitting system with a 2D photonic crystal structure opportunelyfabricated by using conventional optical lithography to reduce the total internal reflection of the emitted light. The extractionefficiency in such devices increases by a factor of 4 at a resonance wavelength.

Sport in Psychiatric Rehabilitation: A Tool in Pre-Acute, Post-Acute and Chronic Phase

引用

International Journal of Clinical Medicine 2011年第5期2卷 568-569页

作者： giorgio Corretti Christian Martini pier L. Greco Francesco P. Marchetti 不详

The principal goal of psychiatric rehabilitation is to improve the global functioning of a person who suffer from a mental disorder. New emerging groups of patients meet difficult to attend to a rehabilitation program. Sport represents a new flexible model that can be used in psychiatric rehabilitation. Sport improves physical health and well being, increases sociality, increases self-efficacy and self-esteem. It is well accepted and well tolerated by the patients, too. Its use goes over the chronic phase of illness (typical target of rehabilitation) and it extends to the post-acute and pre acute phase, too.

Eye Movement Modeling Examples as a Teaching Tool for Epidural Block

引用

Open Journal of Anesthesiology 2023年第4期13卷 75-84页

作者： Emanuele Capogna Marco Scorzoni Gian Luigi Gonnella Matteo Velardo pier Paolo Giurì Mariano Ciancia Gaetano Draisci giorgio Capogna European School of Obstetric Anesthesia (EESOA) Roma Italy Department of Anesthesiology Catholic University Medical School-Fondazione Policlinico Gemelli IRCCS Roma Italy

Introduction: Video examples with task demonstrations by experts, with the expert’s eye movements superimposed on the task, are known as “eye movement modeling examples” (EMME). We performed this study to evaluate if there were improvements in the performance of anesthesia novice trainees when executing the epidural technique after an EMME of epidural block procedure. Methods: We developed an eye movement modeling example (EMME) from eye tracking recordings made by experienced anesthesiologists with more than 20 years of experience. Forty-two PGY3 anesthesia trainees who had never previously performed an epidural block were randomized to receive (study group) or not receive (control group) the EMME video before their institutional training. All the trainees were evaluated every 10 epidural blocks until the end of the rotation period, by an independent, blinded observer using the Global Rating Scale for Epidural Anesthesia (GRS). Results: Trainees who received the EMME training exhibited more respect for the patient’s tissues (P Discussion: This is the first study that has used the EMME for a practical, clinical teaching purpose on real patients and that has used it as an aid in teaching epidural anesthesia. We demonstrated that inexperienced trainees who received the EMME training improved their proficiency at epidural blocks as compared to those who had no EMME training beforehand. Given this result, we welcome further studies to investigate the impact and the role of EMME on clinical teaching in the field of anesthesia.
