Interfacial Passivation Engineering for Highly Efficient Quantum Dot Light-Emitting Diodes via Aromatic Amine-Functionalized Dipole Molecules.

Blue quantum dot (QD) light-emitting diodes (QLEDs) exhibit unsatisfactory operational stability and electroluminescence (EL) properties due to severe nonradiative recombination induced by large numbers of dangling bond defects and charge imbalance in QD. Herein, dipolar aromatic amine-functionalized molecules with different molecular polarities are employed to regulate charge transport and passivate interfacial defects between QD and the electron transfer layer (ETL). The results show that the stronger the molecular polarity, especially with the -CF groups possessing a strong electron-withdrawing capacity, the more effective the defect passivation of S and Zn dangling bonds at the QD surface.

Defect passivation and electron band energy regulation of a ZnO electron transport layer through synergetic bifunctional surface engineering for efficient quantum dot light-emitting diodes.

Zinc oxide nanoparticles (ZnO NPs) have been actively pursued as the most effective electron transport layer for quantum-dot light-emitting diodes (QLEDs) in light of their unique optical and electronic properties and low-temperature processing. However, the high electron mobility and smooth energy level alignment at QDs/ZnO/cathode interfaces cause electron over-injection, which aggravates non-radiative Auger recombination. Meanwhile, the abundant defects hydroxyl group (-OH) and oxygen vacancies (O) in ZnO NPs act as trap states inducing exciton quenching, which synergistically reduces the effective radiation recombination for degrading the device performance.

Balanced carrier injection of quantum dots light-emitting diodes: the case of interface barrier of bilayer ZnO electron transport layer.

Unbalanced carrier injection is one of the most important reasons for the efficiency roll-off in quantum dot light-emitting diodes. Reducing the electron injection can effectively balance the carrier transport and improve the optoelectronic performance of the device. In this work, a bilayer ZnO electron transport layer was fabricated by twice spin-coating and annealing methods.

Distinguishing Benign from Malignant Circumscribed Orbital Tumors in Children.

An orbital neoplasm in children is an uncommon clinical finding. Clinical suspicion should be based on many factors, including its location, the nature of onset, associated systemic signs and symptoms, family and social histories, examination findings, and radiographic characteristics. We present two cases of young children of similar age with a rapid-onset orbital mass.

Adult patients with uveitis associated with juvenile idiopathic arthritis: a retrospective review.

Objective: To describe clinical characteristics and outcomes of adults with uveitis associated with juvenile idiopathic arthritis (JIA).

Methods: Retrospective chart review from 2001 to 2014 of adult patients with JIA and follow-up ≥2 months. Outcome measures included visual acuity, intraocular pressure (IOP), inflammation grade, ocular findings/complications, immunosuppressive therapies, and surgeries.

Dermatofibroma of the Eyelid: Immunohistochemical Diagnosis.

A 66-year-old man developed a painless 2 mm to 3 mm recurrent nodule at the left upper eyelid margin. Excision disclosed a spindle cell lesion without frank atypia or mitotic activity growing in a twisted fascicular pattern often referred to as storiform. All the surgical margins were involved with tumor.

Eyelid Eccrine Cyst: An Exceptional Lesion Among Dominant Apocrine Cysts.

A 71-year-old woman developed a small bluish lesion beneath the cilia of the left lower eyelid. Excision and microscopic examination disclosed a cyst with an intimately associated eccrine sweat gland. Immunohistochemistry demonstrated that the cyst's epithelium was strongly CK5/6, CK14, CK7 weakly positive, and gross cystic disease fluid protein-15 and smooth muscle actin negative.

Dermatofibroma of the eyelid with monster cells.

Dermatofibromas are most frequently encountered in women on the lower extremities, often after minor trauma. A recurrent lesion of the right lower eyelid developed in a 64-year-old woman. It harbored "monster cells" that were large, with either multiple nuclei or a single, large, convoluted, and hyperchromatic nucleus.

Chronic Non-infectious Uveitis in Patients with Juvenile Idiopathic Arthritis.

Purpose: To describe clinical findings and analyze treatment evolution of chronic, non-infectious uveitis in patients with juvenile idiopathic arthritis (JIA).

Methods: A total of 82 patients (147 eyes) with JIA-related uveitis treated for ≥2 months were included (78% females; 79% bilateral uveitis; 74% anterior uveitis). Outcome measures were visual acuity (VA), inflammation control, side-effects, and surgical procedures.

Adult-Onset Ligneous Conjunctivitis with Detection of a Novel Plasminogen Gene Mutation and Anti-Plasminogen IgA Antibody: A Clinicopathologic Study and Review of Literature.

Purpose: To report a novel plasminogen gene mutation and detection of anti-plasminogen antibodies in a patient with ligneous conjunctivitis successfully treated with 60% fresh frozen plasma (FFP).

Methods: Retrospective data collected on a 45-year-old Caucasian female presenting with unilateral chronic membranous lesions.

Results: Laboratory investigation demonstrated decreased plasminogen antigen level, plasminogen activity, and rate of plasminogen activation by u-PA or t-PA, and elevated plasminogen activator inhibitor-1.

Ranibizumab in patients with dense cataract and proliferative diabetic retinopathy with rubeosis.

Background: To evaluate the safety of ranibizumab as a surgical adjunct during cataract surgery in patients with proliferative diabetic retinopathy (PDR) with rubeosis, and to evaluate the efficacy and adverse effects of ranibizumab in treating PDR with rubeosis.

Materials And Methods: Three intravitreal injections of 0.5 mg ranibizumab were administered on day-1, months-1 and -2 with cataract surgery 6-16 days after first injection.

Placement of ProKera in the management of ocular manifestations of acute Stevens-Johnson syndrome in an outpatient.

Purpose: To report the clinical use of ProKera (Bio-Tissue, Inc., Miami, FL) under topical anesthesia in an outpatient for the management of ocular manifestations of acute Stevens-Johnson syndrome (SJS).

Methods: Interventional case report.

Mycophenolate mofetil in the treatment of chronic non-infectious, non-necrotizing scleritis.

Purpose: To determine the effectiveness and corticosteroid (CS) sparing capabilities of mycophenolate mofetil (MMF) in the treatment of chronic non-infectious, non-necrotizing scleritis.

Methods: A retrospective chart review of patients treated for scleritis at the Institute of Ophthalmology and Visual Science at New Jersey Medical School was performed. Only those patients taking MMF for greater than or equal to six consecutive months were included.
