Currently, amorphous LiPON prepared by magnetron sputtering is the most employed thin film electrolyte due to its ionic conductivity (∼10−6 S.cm−1), negligible electronic conductivity, absence of grain boundaries and ability to passivate Li metal. Despite the outstanding cycling performance that this combination of properties enables, its moderate conductivity hinders the use microbatteries in Internet of Things applications due to the need for short but high current pulses during communication phases. To better meet this requirement, LiSiPON thin films with ionic conductivities more than ten times greater than that of LiPON have been synthesized, while encountering some challenges in controlling the composition and the reproducibility of the synthesis. Herein, we have synthesized LiSiPON thin films from a set of precursor targets having distinct lithium concentrations. The main results indicate that an increase in the lithium content in the target material significantly enhances its ionic conductivity. Curiously, the most conductive target results in lithium-deficient and poorly conductive thin films that are not particularly reproducible in terms of composition and electrical properties. Our results suggest that lithium migration away from the sputtered area (or racetrack), favored by the high ionic conductivity of the target, is the origin of the resulting Li-deficient films. Finally, we have succeeded in preparing LiSiPO targets with sufficiently low Li-ion conductivity that enable the reproducible deposition of highly conductive LiSiPON solid electrolytes.

Adolescence involves significant reorganization within the medial prefrontal cortex (mPFC), including modifications to inhibitory neurotransmission mediated through parvalbumin (PV) interneurons and their surrounding perineuronal nets (PNNs). These developmental changes, which result in increased PV neuron activity in adulthood, may be disrupted by drug use resulting in lasting changes in mPFC function and behavior. Methamphetamine (METH), which is a readily available drug used by some adolescents, increases PV neuron activity and could influence the activity-dependent maturational process of these neurons. In the present study, we used male and female Sprague Dawley rats to test the hypothesis that METH exposure influences PV and PNN expression in a sex- and age-specific manner. Rats were injected daily with saline or 3.0 mg/kg METH from early adolescence (EA; 30-38 days old), late adolescence (LA; 40-48 days old), or young adulthood (60-68 days old). One day following exposure, effects of METH on PV cell and PNN expression were assessed using immunofluorescent labeling within the mPFC. METH exposure did not alter male PV neurons or PNNs. Females exposed in early adolescence or adulthood had more PV expressing neurons while those exposed in later adolescence had fewer, suggesting distinct windows of vulnerability to changes induced by METH exposure. In addition, females exposed to METH had more PNNs and more intense PV neuron staining, further suggesting that METH exposure in adolescence uniquely influences development of inhibitory circuits in the female mPFC. This study indicates that the timing of METH exposure, even within adolescence, influences its neural effects in females.

Background: Single injection ropivacaine interscalene anesthesia (ISA) is frequently used in Latarjet reconstruction to enhance post-operative analgesia. A potential limitation is the occurrence of severe rebound pain on block resolution. We investigated the effect of intravenous magnesium on post-operative pain, particularly at the transition of block resolution to multimodal analgesia.
Methods: Elective patients (n = 40) having Latarjet open shoulder reconstruction were randomised to receive either intravenous magnesium sulphate 50 mg/kg (M) or normal saline (S) before induction. Post-operatively, a standardised analgesic regimen was used, and post-operative pain was recorded using a verbal numerical rating assessment (VNRA) score. Requirement for injected opioid analgesia was recorded.
Results: ISA provided longstanding analgesia in all patients with block duration slightly prolonged in the magnesium group (16.7(1.0) (S), 17.8(1.3) h (M), p = 0.049). Magnesium resulted in less rebound pain following ISA resolution (VNRA 4.0 (0.6) M, 6.2 (0.8) S, p = 0.03) and lower pain intensity at 24 h. Four patients had nausea and two required rescue opioid injection.
Conclusion: Magnesium before Latarjet surgery results in less rebound pain following ropivacaine block and improves post-operative analgesia. Magnesium may be indicated in major upper limb surgery, where significant pain intensity is anticipated.

背景：单次注射罗哌卡因腋窝间麻醉（ISA）常用于拉塔吉重建术，以加强术后镇痛。其潜在的局限性在于阻滞解除后会出现严重的反跳痛。我们研究了静脉注射镁对术后疼痛的影响，尤其是在阻滞解除向多模式镇痛过渡时：方法：在诱导前，接受拉塔喷射开放式肩关节重建术的择期患者（n = 40）被随机分配到静脉注射硫酸镁 50 毫克/千克（M）或生理盐水（S）。术后采用标准化镇痛方案，并使用口头数字评级评估（VNRA）评分记录术后疼痛情况。记录了注射阿片类镇痛剂的需求：结果：ISA 为所有患者提供了持久的镇痛效果，镁组的阻滞时间略有延长（16.7(1.0) h (S)，17.8(1.3) h (M)，p = 0.049）。镁可减少 ISA 缓解后的反跳痛（VNRA 4.0 (0.6) M，6.2 (0.8) S，p = 0.03），并降低 24 小时后的疼痛强度：结论：Latarjet 手术前服用镁可减少罗哌卡因阻滞后的反跳痛，并改善术后镇痛。镁可用于预期疼痛强度较大的上肢大手术：治疗研究；随机盲法；2 级。

Pulmonary blastoma (PB) is an exceedingly rare and aggressive malignant lung neoplasm that has distinct biphasic morphology. In this report, we document rare manifestations and molecular alterations in PB. A 59-year-old non-smoker female, presented with cough and hemoptysis for 4 months. The high-resolution computed tomography chest scan showed a 3.5x2.7 cm mass in the basal segment of the left lung. Positron emission tomography and computed tomography revealed a fluorodeoxyglucose avid lobulated mass in the superior segment of the lower lobe of the left lung. On core biopsy, the diagnosis of pleomorphic carcinoma in a background of adenocarcinoma was made. A definite diagnosis of pulmonary blastoma was established on the left lung lobectomy specimen based on morphological and immunohistochemical findings. Post-surgical biopsy from the scalp swelling showed metastatic deposits. On Next Generation Sequencing (NGS), in addition to conventional CTNNB1 gene mutation, new pathogenic MYCN and ATM gene mutations were detected. Post-chemotherapy, the patient was doing well after 10 months of close follow-up. PB exhibited rare associations in the form of non-smoker status, scalp metastasis, and MYCN and ATM gene mutations on NGS in addition to conventional CTNNB1 gene mutation. Large cohort studies are required to discover the incidence, significance and therapeutic implications of these co-existing pathogenic molecular alterations in PB.

Commercial solid oxide fuel cells (SOFCs) primarily operate in the intermediate temperature range (600 °C–800 °C); hence, developing cathode materials with good stability and excellent catalytic activity in this temperature range is necessary. Herein, we are reporting the performance of SrCo0.5Fe0.5O3−δ (SCF) and SrCo0.5Fe0.25Cu0.2Nb0.05O3−δ (SCFCN) perovskite oxide as cathode materials for solid oxide fuel cells (SOFCs). The SCFCN sample maintains a cubic structure under a CO2 atmosphere. The polarization resistance of the SCFCN cathode on La0.9Sr0.1Ga0.83Mg0.17O3−δ (LSGM) reaches 0.067 Ωcm2 at 700 °C. The charge transfer and oxygen reduction reactions of the SCFCN cathode on the LSGM electrolyte are the main rate-limiting steps at 600 °C–700 °C. The SCFCN cathode maintains good electrochemical stability during a 200-h test with a configuration of SCFCN/LSGM/SCFCN symmetrical cell. Compared with SCF, the doping of Cu and Nb effectively reduces the Rp attenuation of SCFCN from 0.00012 to 0.00005 Ωcm2/h. The output power density of the fuel cell with SCFCN as the cathode on LSGM reaches 1124 mWcm−2 at 800 °C. This indicates that SCFCN can be a potential material for fabricating cathode for intermediate-temperature SOFCs (IT-SOFCs).

Out of the immense possibilities of developing new materials, processes and mechanisms using ionic liquids, lies the great possibility of employing ionic liquids in the area of battery electrolytes. Battery technology is directly dependent on progress of battery electrolytes. In recent years there has been a fast growing demand of lithium ion batteries (LIBs) in mobile phones, laptops, electric vehicles and related high-voltage electrochemical applications.

The Ruddlesden-Popper phase La2NiO4+δ (LNO214) has received a significant level of research attention with respect to its employment as a Solid Oxide Fuel Cell cathode material. However, it is known that there are many factors that are capable of influencing the performance of this phase when utilised in this role. One such factor that can impact on electrode behaviour is the choice of sintering temperature. In this paper, a study of this effect is detailed. This is achieved via the use of both symmetrical and single cell testing configurations, with additional investigation provided by ex-situ analysis. It is shown that a sizeable improvement in electrode performance can be achieved via an increase in sintering temperature. This is despite observations on the reactivity between LNO214 and the contact electrolyte material Ce0.9Gd0.1O2-δ. Further, it is also demonstrated that the addition of a noble metal contacting layer can dramatically improve the performance of an LNO214 electrode. In comparison, the impact of a contacting layer on a state-of-the-art La0.6Sr0.4Co0.2Fe0.8O3-δ composition is shown to be relatively minor. This has implications towards SOFC testing methodologies given the widespread employment of noble metal contacting pastes.
