Flexible Graphite/PPG Hybrid Composite-Based Resistive Sensor for Sensing Organic Compounds.

Our objective in this study was to investigate a sensor for volatile organic compounds based on a graphite (G)/polypropylene glycol (PPG) hybrid composite (HC) for sensing hybrid elements. The G/PPG HC sensor films for organic-matter detection were successfully fabricated on polyethylene terephthalate (PET) film with a simple blade-coating method. The sensing paste based on G/PPG (1:2) HC showed good dispersibility and stability.

Innovatively Continuous Mass Production Couette-taylor Flow: Pure Inorganic Green-Emitting CsPbBr Perovskite Microcrystal for display technology.

We report for the first time the mass production of CsPbBr perovskite microcrystal with a Couette-Taylor flow reactor in order to enhance the efficiency of the synthesis reaction. We obtained a pure CsPbBr perovskite solid within 3 hrs that then realized a high photoluminescence quantum yield (PLQY) of 46%. Furthermore, the CsPbBr perovskite microcrystal is applied with red emitting KSiF phosphor on a blue-emitting InGaN chip, achieving a high-performance luminescence characteristics of 9.

Effective passivation of Ag nanowire-based flexible transparent conducting electrode by TiO nanoshell.

Silver nanowire-based flexible transparent electrodes have critical problem, in spite of their excellent electrical and optical properties, that the electrical conductance and transparency degrade within several days in air because of oxidation of silver. To prevent the degradation of the silver nanowire, we encapsulated Ag-NWs with thin TiO barrier. Bar-coated silver nanowires on flexible polymer substrate were laminated at 120 °C, followed by atomic layer deposition of TiO nanoshell.

Long-term stable stacked CsPbBr quantum dot films for highly efficient white light generation in LEDs.

We report highly efficient ethyl cellulose with CsPbBr perovskite QD films for white light generation in LED application. Ethyl cellulose with CsPbBr quantum dots is applied with SrSiN : Eu red phosphor on an InGaN blue chip, achieving a highly efficient luminous efficacy of 67.93 lm W under 20 mA current.

Short-term effect of botulinum toxin a injection on spastic equinovarus foot in cerebral palsy patients: a study using the foot pressure measurement system.

Objective: To evaluate the therapeutic effect of botulinum toxin A (BTX-A) injection on spastic gastrocnemius (GCM) and tibialis posterior muscles (TPo) by using the foot pressure measurement system (FPMS).

Methods: Eighteen ambulatory CP patients were recruited in this study. BTX-A was injected into the GCM at a dose of 6-12 units/kg and TPo at a dose of 4-9 units/kg according to the severity of equinus and varus deformity.

Relation between cognition and neural connection from injured cingulum to brainstem cholinergic nuclei in chronic patients with traumatic brain injury.

Background: This study investigated the relation between cognition and the neural connection from injured cingulum to brainstem cholinergic nuclei in patients with traumatic brain injury (TBI), using diffusion tensor tractography (DTT).

Methods: Among 353 patients with TBI, 20 chronic patients who showed discontinuation of both anterior cingulums from the basal forebrain on DTT were recruited for this study. The Wechsler Intelligence Scale and the Memory Assessment Scale (MAS; short-term, verbal, visual and total memory) were used for assessment of cognition.

Characteristics of injury of the corticospinal tract and corticoreticular pathway in hemiparetic patients with putaminal hemorrhage.

Background: No study on the characteristics of injury of the corticospinal tract (CST) or corticoreticular pathway (CRP) in patients with putaminal hemorrhage has been reported. In this study, using diffusion tensor tractography, we attempted to investigate the characteristics of injury of the CST and CRP in hemiparetic patients with putaminal hemorrhage.

Method: Fifty seven consecutive patients with putaminal hemorrhage and 57 healthy control subjects were recruited for this study.
