Modulation of Electrostatic Potential in 2D Crystal Engineered by an Array of Alternating Polar Molecules.

The moiré potential in rotationally misfit two-dimensional (2D) heterostructures has been used to build artificial exciton and electron lattices, which have become platforms for realizing exotic electronic phases. Here, we demonstrate a different approach to create a superlattice potential in 2D crystals by using the near field of an array of polar molecules. A bilayer of titanyl phthalocyanine (TiOPc), consisting of alternating out-of-plane dipoles, is deposited on monolayer MoS.

Nanoscale Periodic Trapping Sites for Interlayer Excitons Built by Deformable Molecular Crystal on 2D Crystal.

The nanoscale moiré pattern formed at 2D transition-metal dichalcogenide crystal (TMDC) heterostructures provides periodic trapping sites for excitons, which is essential for realizing various exotic phases such as artificial exciton lattices, Bose-Einstein condensates, and exciton insulators. At organic molecule/TMDC heterostructures, similar periodic potentials can be formed via other degrees of freedom. Here, we utilize the structure deformability of a 2D molecular crystal as a degree of freedom to create a periodic nanoscale potential that can trap interlayer excitons (IXs).

Radical Alkynylations with EthynylBenziodoXolones: from Photocatalysis to Direct Excitation.

Ethynylbenziodoxolones (EBXs) have recently emerged as potent reagents for the alkynylation of radicals. Their combination with photocatalysis allows the synthesis of valuable alkynes at room temperature. Herein, we discuss two photomediated strategies for the synthesis of internal alkynes.

Direct Photoexcitation of Ethynylbenziodoxolones: An Alternative to Photocatalysis for Alkynylation Reactions*.

Ethynylbenziodoxolones (EBXs) are commonly used as radical traps in photocatalytic alkynylations. Herein, we report that aryl-substituted EBX reagents can be directly activated by visible light irradiation. They act as both oxidants and radical traps, alleviating the need for a photocatalyst in several reported EBX-mediated processes, including decarboxylative and deboronative alkynylations, the oxyalkynylation of enamides and the C-H alkynylation of THF.

Photocatalytic Umpolung of - and -substituted alkenes for the synthesis of 1,2-amino alcohols and diols.

We report an organophotocatalytic 1,2-oxyalkynylation of ene-carbamates and enol ethers using Ethynyl BenziodoXolones (EBXs). 1-Alkynyl-1,2-amino alcohols and diols were obtained in up to 89% yield. Photocatalytic formation of radical cations led to Umpolung of the innate reactivity of the alkenes, enabling addition of a nucleophilic benzoate followed by radical alkynylation.

Photocatalysis with organic dyes: facile access to reactive intermediates for synthesis.

Organic dyes have emerged as a reliable class of photoredox catalysts. Their great structural variety combined with the easy fine-tuning of their electronic properties has unlocked new possibilities for the generation of reactive intermediates. In this review, we provide an overview of the available approaches to access reactive intermediates that employ organophotocatalysis.

Metal-Free Electrophilic Alkynylation of Sulfenate Anions with Ethynylbenziodoxolone Reagents.

Alkynyl sulfoxides are important building blocks with a unique reactivity in organic chemistry, but only a few reliable methods have been reported to synthesize them. A novel route to access alkynyl sulfoxides is reported herein by using ethynyl benziodoxolone (EBX) reagents to trap sulfenate anions generated in situ, via a retro-Michael reaction. The reaction takes place under metal-free and mild conditions.

Picture this: a photovoice study of international students' food experience in Canada.

Purpose: International student enrolment in Canadian universities is increasing. As international university students acculturate, they experience a culture shock in which food plays a major role. International university students' Canadian food experiences therefore were explored.

Telemedicine in a rural memory disorder clinic-remote management of patients with dementia.

Background: There are many reasons to develop telemedicine clinics for assessment and management of dementia. Time constraints, location, and poor weather conditions can all impact on the ability of patients and providers to attend rural clinics. The utility of telemedicine in the diagnosis of dementia and subsequent follow-up appears promising in the literature, as it provides a viable means of assessing cognition in patients in remote areas with limited access to medical specialists.

Difficulties encountered in collaborative care: logistics trumps desire.

Introduction: This study examines the development of collaborative relationships between family physicians (FPs) and Anticipatory And Preventative Team Care (APTCare) team members providing care to medically complex patients who have been identified as at-risk for negative health outcomes.

Methods: We undertook a qualitative study of a primary health care intervention in a family practice. Interviews were held with FPs and ATPCare intervention nurse practitioners (NPs) and pharmacists.

Feasibility of providing nephrology services to remote communities with videoconferencing.

We examined the feasibility of telemedicine clinics for patients with chronic kidney disease (not on dialysis) for a period of 18 months. Telemedicine clinics were run at two peripheral hospitals about 100 km from the specialist hospital in Ottawa. A total of 115 questionnaires were completed by patients and providers during the period March 2009 to July 2009.

Clinical pathways: adherence issues in complex older female patients with heart failure (HF).

HF is a leading health care concern, often under-recognized and under-treated in older women. Management of this complex condition frequently requires a multidisciplinary approach and a clinical pathway can be used to deliver coordinated care. This report is based on the intervention/treatment arm (n = 45) of a randomized controlled trial in older women who participated in a multidisciplinary clinic.

Integration of nurse practitioners into a family health network.

A randomized controlled study called Anticipatory and Preventative Team Care (APTCare) explored a new role for nurse practitioners (NPs) within a multidisciplinary team. The aim of the study was to evaluate whether integrating NPs and a pharmacist was an effective approach for the management of patients living with multiple chronic illnesses. Over an 18-month period, three part-time NPs and a pharmacist became part of a rural Family Health Network (FHN).

Interprofessional education in palliative care: a pilot project using popular literature.

A need to introduce the concepts of death and dying to the medical and health sciences undergraduate curriculum was identified at the University of Ottawa, Ontario, Canada. As care of the terminally ill is complex and requires the collaborative involvement of a diverse group of health care professionals, an interprofessional educational approach was utilized to address this need. A seminar course was developed using popular literature as the basis for learning, and offered to first and second year medical students, fourth year nursing students and graduate students in spiritual care.

Evaluation of in-hospital management of fracture risk in older patients: a chart review study of tertiary prevention.

Hip fractures are associated with considerable morbidity and mortality in the elderly. Both fall prevention strategies and bone integrity/osteoporosis assessment should be addressed in this population. This study's goal was to evaluate the management of potential re-fracture risk after a hip fracture in an acute care setting.

A continuing medical education initiative for canadian primary care physicians: the driving and dementia toolkit: a pre- and postevaluation of knowledge, confidence gained, and satisfaction.

This study examined the effect of the Driving and Dementia Toolkit on physician knowledge and confidence gained and the anticipated change in patient assessment and evaluated the extent to which physicians found the material to be useful. Before receiving the driving toolkit, 301 randomly selected primary care physicians received a copy of the pretest questionnaire; 145 responded and met the eligibility criteria. This group was then sent the toolkit, a satisfaction a survey, and a posttest questionnaire.
