In many optoelectronic applications, patterning is required for functional and/or aesthetic purposes. However, established photolithographic technique can't be applied directly to the hybrid perovskites, which are considered as promising candidates for optoelectronic applications. In this work, a wettability-assisted photolithography (WAP) process, which employs photolithography and one-step solution process to deposit hybrid perovskite, was developed for fabricating patterned hybrid perovskite films. Uniform pinhole-free hybrid perovskite films with sharp-edged micro-patterns of any shapes can be constructed through the WAP process...

We present the enhanced photoluminescence (PL) of a corrugated Al2O3 film enabled by colloidal CdSe quantum dots. The colloidal CdSe quantum dots are fabricated directly on a corrugated Al2O3 substrate using an electrochemical deposition (ECD) method in a microfluidic system. The photoluminescence is excited by using a 150 nm diameter ultraviolet laser spot of a scanning near-field optical microscope. Owing to the electron transfer from the conduction band of the CdSe quantum dots to that of Al2O3, the enhanced photoluminescence effect is observed, which results from the increase in the recombination rate of electrons and holes on the Al2O3 surface and the reduction in the fluorescence of the CdSe quantum dots...

A vacuum assisted UV micro-molding (VAUM) process is proposed for the fabrication of freestanding and defect-free polymer membranes based on a UV-curable methacrylate polymer (MD 700). VAUM is a highly flexible and powerful method for fabricating low cost, robust, large-area membranes over 9 × 9 cm(2) with pore sizes from 8 to 20 μm in diameter, 20 to 100 μm in thickness, high aspect ratio (the thickness of the polymer over the diameter of the hole is up to 15 : 1), high porosity, and a wide variety of geometrical characteristics...

In this work, the microfluidic-assisted synthesis of copper-tetracyanoquinodimethane (Cu-TCNQ) nanostructures in ambient environment is reported for the first time. A two-layer microfluidic device comprising parallel actuated microchambers was used for the synthesis and enabled an excellent fluid handling for the continuous and multiple chemical reactions in confined ultra-small chambers. Different precautions were applied to ensure the reduction state of copper for the synthesis of Cu-TCNQ charge-transfer compounds...

The electrical storm is a life-threatening situation which causes a complex antiarrhythmic treatment. We firstly report a rhythmological stabilization through mechanical unloading of the left ventricle in a health patient who developed electrical storm after endo- and epicardiac re-ablation and who previously underwent 27 unsuccessful defibrillations. No evidence for a specific etiology of the rhythm disturbances was found. After implantation of a percutaneous left ventricular assist device (pLVAD) a single additional defibrillation was needed to terminate ventricular fibrillation...

We report on the fully percutaneous insertion and removal of the Impella 5.0 microaxial flow device via the axillary artery in a patient with cardiogenic shock and peripheral artery disease. Due to inadequate iliofemoral vasculature and desire for mobility, the axillary artery was felt to be the most appropriate access approach for temporary mechanical circulatory support. The procedure was well tolerated and the patient was supported for 17 days, at which time the device was safely removed in a fully percutaneous manner at the time of permanent left ventricular assist device placement...

OBJECTIVES: Over 30% of critically ill patients on positive-pressure mechanical ventilation have difficulty weaning from the ventilator, many of whom acquire ventilator-induced diaphragm dysfunction. Temporary transvenous phrenic nerve pacing using a novel electrode-bearing catheter may provide a means to prevent diaphragm atrophy, to strengthen an atrophied diaphragm, and mitigate the harms of mechanical ventilation. We tested the initial safety, feasibility, and impact on ventilation of this novel approach...

PURPOSE OF REVIEW: Cardiac transplant remains the gold standard of care for patients with end-stage heart failure. Unfortunately, due to the limited availability of donor hearts in the United States, not all eligible candidates are able to be transplanted. Since the introduction of mechanical assist devices for the treatment of advanced heart failure, patients gain a significant survival benefit while awaiting transplant. With rapidly evolving technology, it is important to appreciate the advances in the current use of mechanical assist devices...

Increased survival rates after corrective or palliative surgery for complex congenital heart disease (CHD) in infancy and childhood are now being coupled with increased numbers of patients who survive to adulthood with various residual lesions or sequelae. These patients are likely to deteriorate in cardiac function or end-organ function, eventually requiring lifesaving treatment including heart transplantation. Although early and late outcomes of heart transplantation have been improving for adult survivors of CHD, outcomes and pretransplant management could still be improved...

PURPOSE: The use of an argatroban-based percutaneous ventricular assist device (pVAD) purge solution in a patient with suspected heparin-induced thrombocytopenia (HIT) is described. SUMMARY: A 70-year-old woman in cardiogenic shock was admitted to a coronary care unit after being discovered unresponsive at home. A transthoracic echocardiogram revealed a low ejection fraction and findings consistent with takotsubo cardiomyopathy. Administration of multiple inotropes and vasopressors was initially required for hemodynamic support...

This case report describes the successful resuscitation of an 11-year-old boy who suffered out-of-hospital cardiac arrest (OHCA) using mechanical cardiopulmonary resuscitation (CPR) by adapting the Lund University Cardiopulmonary Assist System (LUCAS)(2) Device by rolling a blanket under the patient's back to increase his chest height, thus allowing the LUCAS device to administer compliant CPR.

BACKGROUND: Currently, the cryopreservation of embryos and oocytes is essential for assisted reproductive technology (ART) laboratories worldwide. This study aimed to evaluate the efficacy of the Kitasato Vitrification System (KVS) as a vitrification device for the cryopreservation of mouse embryos to determine whether this novel device can be adapted to the field of ART. METHODS: In Experiment 1, blastocysts were vitrified using the KVS. Vitrified blastocysts were warmed and subsequently cultured for 72 h...

DESIGN: A case series of 5 patients with multilevel cervical myelopathy treated by French-door cervical laminoplasty (FDCL) and use of unicortical iliac crest graft as spacer fixed with titanium miniplates and screws is described. OBJECTIVE: To report a minimum of 6-year follow-up results of our new plate-screw fixation technique for FDCL. SUMMARY OF BACKGROUND DATA: Hardware-assisted laminoplasty has the potential advantage of preventing restenosis by holding the laminar door "open" while healing progresses and also prevents spacer dislodgement...

INTRODUCTION: Although there has been substantial emphasis on the neuromuscular and cardiovascular adaptations following rehabilitation, pulmonary adaptations in individuals with incomplete SCI (iSCI) in response to locomotor training have been less frequently studied. In healthy individuals, effective transition from rest to work is accomplished by a hyperpneic response, which exhibits an exponential curve with three phases. However, the degree to which our current understanding of exercise hyperpnea can be applied to individuals with iSCI is unknown...

BACKGROUND: The impact of aortic insufficiency (AI) on the morbidity and mortality of left ventricular assist device (LVAD) patients remains controversial. This study's aim is to assess the hemodynamics of LVAD patients with at least mild AI, at baseline and in response to device speed changes. METHODS: Asymptomatic LVAD patients were prospectively enrolled and underwent a hemodynamic and echocardiographic ramp study. Hemodynamics at rest and in response to device speed changes were compared between patients with at least mild AI at their baseline speed and patients without AI...
