Electrochemical Properties of Polyaniline-Coated Li-Rich Nickel Manganese Oxide and Role of Polyaniline Coating Layer

Polyaniline is coated on Li[Li 0.2 Ni 0.2 Mn 0.6 ]O 2 synthesized via co-precipitation. X-ray diffraction patterns exhibit that the polyaniline coating does not affect structural change of the Li[Li 0.2 Ni 0.2 Mn 0.6 ]O 2 , and the resulting transmission electron microscopic images show the presence of coating layers on the surface of Li[Li 0.2 Ni 0.2 Mn 0.6 ]O 2 . Electrochemical tests using coin type cells confirm that the surface modification by polyaniline is effective in maintaining capacity and retention upon cycling. The conducting coating character also assists improvement in rate capability. The polyaniline layer forms F-doped polyaniline during cycling, as is proved by time-of-flight secondary ion mass spectroscopy. Therefore, the presence of the polyaniline layers plays a role in lowering HF levels via scavenging F − from HF in the electrolyte, and this F-doped polyaniline layer also assists in protecting the Li [Li 0.2 Efforts have been made to improve their intrinsic low rate capability stemming from the tetravalent Mn in the oxide matrix and cyclability as well. Hence, partial substitutions of Mn site with other elements or surface modifications have been made. 10,12 A recent report by Kang et al. 14 suggested that surface modification by Al(OH) 3 on Li[Li 0.2 Ni 0.2 Mn 0.6 ]O 2 was fairly effective in capacity retention, rate capability, and thermal stability. Similar effects were also reported using Al 2 O 3 coating and AlPO 4 coating on the over-lithiated manganese oxides. 17,18 Furthermore, we perceive the main problem of oxide coating to be difficulty in complete encapsulation of active materials like core-shell materials due to condensation and crystal growth of the coating materials even at mild heat-treatment condition; it, hence, shows an islands-like coating. 18 For the reason, we object to complete encapsulation of Li[Li 0.2 Ni 0.2 Mn 0.6 ]O 2 using a conductive polyaniline, which does not need further heat-treatment after polymerization. Also, the conductive coating layers are expected to improve the rate capability of the active material. In this paper, we introduce the details of polyaniline-coated Li [ • C for 5 h. The dehydrates were thoroughly mixed with an appropriate amount of LiOH (samchun) and calcined at 900 • C for 15 h in air. In attempt to modify the as-synthesized active materials with polyaniline (hereafter referred as to be PANi), Cl − -doped emeraldine salt state PANi ([C 24 H 26 N 4 (Cl) 2 ] n ) was polymerized with aniline monomer (C 6 H 5 NH 2 ) and ammonium persulfate ((NH 4 ) 2 S 2 O 8 ,). First, aniline monomer and ammonium persulfate were separately poured into 1M HCl aqueous solution, and they were mixed to self-polymerize for 2 days. And the produced PANi in the solution was rinsed with absolute ethanol and acetone to remove the residual monomer, oligomer, and low molecular weight organic intermediates. To prepare violet pernigraniline base state (hereafter referred as to be VPB) PANi which needs to be dissolved in N-methyl-2-pyrrolinon(NMP) or m-cresol and so on, 19,20 the Cl − -doped PANi was poured into a 1M NaOH aqueous solution and continuously stirred at 350 rpm for 2 days. Then, the solution was dried at 80 • C in air. The obtained VPB powders were mixed with campor-10-sulfonic acid, β (CSA, Sigma-aldrich, with a ratio of 4:1 in weight) to prepare (SO) 3 2− -doped emeraldine salt state (hereafter referred as to be ES) PANi and dissolved into N-methyl-2-pyrrolinon (NMP X-ray diffractometry (XRD, Rint-2000, Rigaku) and highresolution transmission electron microscopy (HR-TEM, JEM-3010, JEOL) were employed to characterize the synthesized powders. Timeof-flight secondary ion mass spectroscopy (ToF-SIMS, PHI TRIFT V nanoTOF, ULVAC-PHI) was also used to confirm the presence of th

Effect of 660 nm Light-Emitting Diode on the Wound Healing in Fibroblast-Like Cell Lines

Light in the red to near-infrared (NIR) range (630–1000 nm), which is generated using low energy laser or light-emitting diode (LED) arrays, was reported to have a range of beneficial biological effects in many injury models. NIR via a LED is a well-accepted therapeutic tool for the treatment of infected, ischemic, and hypoxic wounds as well as other soft tissue injuries in humans and animals. This study examined the effects of exposure to 660 nm red LED light at intensities of 2.5, 5.5, and 8.5 mW/cm2 for 5, 10, and 20 min on wound healing and proliferation in fibroblast-like cells, such as L929 mouse fibroblasts and human gingival fibroblasts (HGF-1). A photo illumination-cell culture system was designed to evaluate the cell proliferation and wound healing of fibroblast-like cells exposed to 600 nm LED light. The cell proliferation was evaluated by MTT assay, and a scratched wound assay was performed to assess the rate of migrating cells and the healing effect. Exposure to the 660 nm red LED resulted in an increase in cell proliferation and migration compared to the control, indicating its potential use as a phototherapeutic agent

Electro-Mechanical Safety Testing of Portable ECG Devices for Home Healthcare Usage

OBJECTIVES: This paper suggests the experimental guidelines to evaluate the electro-mechanical safety of belt type equipment. The electro-mechanical safety was determined by using the International Electrotechnical Commission guidelines, which are widely used as important factors for assessing the electro-mechanical safety of belt type equipment. However, the local guidelines on wearable healthcare sensors are currently not well-established. Therefore, safety guidelines suited for the actual circumstances in Korea are required, and this paper attempts to try a new experimental safety test procedure of the wearable healthcare sensor. METHODS: This belt type device measures the electrocardiogram (ECG) and heart rates by attaching to the chest. Examination lists were selected by analyzing the common standards ofelectro-mechanical safety (IEC 60601-1) and environment tests (IEC 60068-1, IEC 60068-2) of home-healthcare equipment. RESULTS: The essential electrical safety, which was required for the RS300G3 as a medical device, was evaluated, and most of the examination lists were selected by considering the circumstances of the users. The device passed all the selected examinable lists that are applicable to the Korean environment. CONCLUSIONS: This study has limitations to estimate and to conduct electro-mechanical safety experiments because our study focused on the belt type of heart-rates equipment. We are not taking into account the overall electro-mechanical home-healthcare measurements. According to industrial and technological development, there are infinite possibilities for the advancement of home-healthcare equipment, so more examination lists for safety are being added in addition to what we have doneope

Evaluation for Damaged Degree of Vegetation by Forest Fire Using LiDAR and Digital Aerial Photograph

The amount of vegetation physically damaged by forest fire can be evaluated using lidar (Light Detection And Ranging) data because the loss of canopy height and width by forest fire can be relevant to the number of points transmitted to the ground through the canopy of the damaged forest. On the other hand, the biological damage of vegetation caused by forest fire can be obtained from the Normalized Difference Vegetation Index (NDVI), which determines the vegetation vitality. In this study, the degree of physical damage from the lidar data was classified into serious physical damage (SPD) and light physical damage (LPD). The degree of biological damage using NDVI was likewise classified into serious biological damage (SBD) and light biological damage (LBD). Finally, the damaged area was graded into four categories: (a) SPD and SBD, (b) LPD and SBD, (c) SPD and LBD, and (d) LPD and LBD. The accuracy assessment for the area classified into four grades showed an overall accuracy of 0.74, and a kappa value of 0.61 which provides improvement over previous works

A novel sphingosylphosphorylcholine and sphingosine-1-phosphate receptor 1 antagonist, KRO-105714, for alleviating atopic dermatitis

Background Atopic dermatitis (eczema) is a type of inflammation of the skin, which presents with itchy, red, swollen, and cracked skin. The high global incidence of atopic dermatitis makes it one of the major skin diseases threatening public health. Sphingosylphosphorylcholine (SPC) and sphingosine-1-phosphate (S1P) act as pro-inflammatory mediators, as an angiogenesis factor and a mitogen in skin fibroblasts, respectively, both of which are important biological responses to atopic dermatitis. The SPC level is known to be elevated in atopic dermatitis, resulting from abnormal expression of sphingomyelin (SM) deacylase, accompanied by a deficiency in ceramide. Also, S1P and its receptor, sphingosine-1-phosphate receptor 1 (S1P1) are important targets in treating atopic dermatitis. Results In this study, we found a novel antagonist of SPC and S1P1, KRO-105714, by screening 10,000 compounds. To screen the compounds, we used an SPC-induced cell proliferation assay based on a high-throughput screening (HTS) system and a human S1P1 protein-based [35S]-GTPγS binding assay. In addition, we confirmed the inhibitory effects of KRO-105714 on atopic dermatitis through related cell-based assays, including a tube formation assay, a cell migration assay, and an ELISA assay on inflammatory cytokines. Finally, we confirmed that KRO-105714 alleviates atopic dermatitis symptoms in a series of mouse models. Conclusions Taken together, our data suggest that SPC and S1P1 antagonist KRO-105714 has the potential to alleviate atopic dermatitis.This work was supported by a grant from the Korea Research Council for Industrial Science and Technology (KK-1933-20) to HC, under the industrial infrastructure program for fundamental technologies and Korea Institute for Advancement of Technology through the Inter-ER Cooperation Projects (R0002017) which are funded by the Ministry of Trade, Industry & Energy, Korea to YDG

Synchronous double primary cancers associated with a choledochal cyst and anomalous pancreaticobiliary ductal union

A 60-year-old female was admitted with epigastric pain lasting a month. Preoperative diagnosis was choledochal cyst with anomalous pancreaticobiliaryductal union (APBDU), C-P type. A papillary mass measuring 2.5 × 1.9 cm was found adjacent to the pancreaticocholedochal junction. Gallbladder (GB) cancer was also observed. Pyloric-preserving pancreaticoduodenectomy (PPPD) was performed. The patient received adjuvant chemotherapy/radiation therapy on the tumor bed. The gallbladder cancer showed serosal invasion, while the bile duct cancer extended into the pancreas. Although common bile duct (CBD) cancer lesion showed focally positive for p53 and the gallbladder cancer lesion showed negative for p53, the Ki-67 labeling index of the CBD cancer and GB cancer were about 10% and 30%, respectively. Nine months after curative resection, a stricture on the subhepatic colon developed due to adjuvant radiation therapy. Localized peritoneal seedings were incidentally found during a right hemicolectomy. The patient underwent chemotherapy and had no evidence of tumor recurrence for two years after PPPD
