Construct: The purpose of this study was to provide validity evidence for the mini-clinical evaluation exercise (mini-CEX) as an assessment tool for clinical skills in the workplace. BACKGROUND: Previous research has demonstrated validity evidence for the mini-CEX, but most studies were carried out in internal medicine or single disciplines, therefore limiting generalizability of the findings. If the mini-CEX is to be used in multidisciplinary contexts, then validity evidence should be gathered in similar settings...

Organic molecules with wide absorption spectra exhibit great sunlight harvesting capability and are critically important for solar cell applications. In this manuscript, we develop an A-D-A'-D-A type small molecule acceptor (IID-IC) using isoindigo (IID) as the electron-deficient core unit (A'), thiophene as the electron-rich bridging units (D) and 2-(3-oxo-2,3-dihydroinden-1-ylidene)malononitrile (IC) as the electron-deficient endcapping groups (A). IID-IC shows a wide absorption spectrum with the full width at half maximum (FWHM) of 190 nm, which is almost twice that of a typical A-D-A type molecule acceptor...

Organic field-effect transistor (OFET) performance is dictated by its composition and geometry, as well as the quality of the organic semiconductor (OSC) film, which strongly depends on purity and microstructure. When present, impurities and defects give rise to trap states in the bandgap of the OSC, lowering device performance. Here, 2,8-difluoro-5,11-bis(triethylsilylethynyl)-anthradithiophene is used as a model system to study the mechanism responsible for performance degradation in OFETs due to isomer coexistence...

On the basis of an in situ photoemission spectroscopy (PES) system, we propose a novel, direct diagnosis method for the characterization of graphene (Gr) doping states at organic semiconductor (OSC)/electrode interfaces. Our in situ PES system enables ultraviolet/X-ray photoelectron spectroscopy (UPS/XPS) measurements during the OSC growth or removal process. We directly deposit C60 films on three different p-type dopants-gold chloride (AuCl3), (trifluoromethyl-sulfonyl)imide (TFSI), and nitric acid (HNO3)...

We have examined the structural, electronic, and optical properties of zinc-octaethylporphyrin [Zn(OEP)]/C60 co-deposited films to elucidate the donor (D)-acceptor (A) interactions at the D/A interface of heterojunction organic solar cells (OSCs), using Fourier-transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), ultraviolet-visible (UV-vis) spectroscopy, and photoluminescence (PL) spectroscopy in combination with first-principles and semi-empirical calculations. The FT-IR and XRD results indicated that Zn(OEP) and C60 were mixed with each other at the molecular level in the co-deposited film...

The filamentous anoxygenic phototrophic bacterium Oscillochloris trichoides DG-6 has been studied, and it has been shown that there are no lipopolysaccharides on the cell surface. Fatty acids hydroxylated at the C3 position, amino sugars and phosphate-containing compounds characteristic of lipid A have also not been found. The genes encoding for proteins responsible for the synthesis of lipopolysaccharides and the genes for the transport system, usually localized in the outer membrane of Gram-negative bacteria, have not been detected in the genome...

The research on bulk heterojunction (BHJ) organic solar cells (OSCs) is rapidly growing from the past two decades and the device performance has reached power conversion efficiency over 13%. In this minireview we have highlighted the design strategies used for the development of diketopyrrolopyrrole (DPP) and tetracyano based molecular donors. We have also described how tetracyano bridged non-fullerene acceptors can be developed by click type [2+2] cycloaddition-retroelectrocyclization reaction of acetylene bridged small molecule with tetracyanoethylene (TCNE) by simple modification...

The power conversion efficiencies (PCEs) of state-of-the-art organic solar cells (OSCs) have increased to over 13%. However, the most commonly used solvents for making the solutions of photoactive materials and the coating methods used in laboratories are not adaptable for future practical production. Therefore, taking a solution-coating method with environmentally friendly processing solvents into consideration is critical for the practical utilization of OSC technology. In this study, a highly efficient PBTA-TF:IT-M-based device processed with environmentally friendly solvents, tetrahydrofuran/isopropyl alcohol (THF/IPA) and o-xylene/1-phenylnaphthalene, is fabricated; a high PCE of 13...

Traditional examination has inherent deficiencies. Objective Structured Clinical Examination (OSCE) is considered as a method of assessment that may overcome many such deficits. OSCE is being increasingly used worldwide in various medical specialities for formative and summative assessment. Although it is being used in various disciplines in our country as well, its use in the stream of general surgery is scarce. We report our experience of assessment of undergraduate students appearing in their pre-professional examination in the subject of general surgery by conducting OSCE...

Triplet materials have been employed to achieve high performing OSCs, while the triplet nonfullerene acceptor materials have never been reported for bulk heterojunction OSCs. Herein, for the first time, three triplet molecular acceptors based on tellurophene with different extent of ring fusing were designed and synthesized for OSCs. Significantly, these molecules possess long exciton lifetime and diffusion length, leading to efficient power conversion efficiency (7.52%), which is the highest values for tellurophene based OSCs...

INTRODUCTION: Although recent literature suggests that students should be trained in the care of persons with disability (PWDs) as a form of cultural sensitivity (CS), healthcare professionals may receive limited experience during their formal training. After pharmacy students in 2 previous years of testing failed to adequately assess and plan for the care of a standardized patient's chief complaint and disability in an Objective Structured Clinical Examination (OSCE), the investigators added debriefing to the OSCE to determine if it would improve student's ability to assess and plan for the care of PWD...
