Many physical processes such as exciton interfacial dissociation, exciton interfacial recombination, and exciton-electron and exciton-hole interactions coexist at the interface of organic solar cells (OSC). In this study, the direction of free charge generation is defined as the direction from the interface to the side where free charges are left. For a p-n type device, the direction of free electron (hole) generation from exciton dissociation at the donor/accepter (D/A) interface is the same as the subsequent transportation direction under the built-in electric field...

The article presents the results of work on the Polish adaptation of the Death Attitude Profile-Revised by Wong, Reker, and Gesser (1994). The psychometric properties of the Polish version of the tool have been described. The results are consistent with the original version of the questionnaire and confirm that the Polish version of Death Attitude Profile-Revised fulfils the psychometric requirements for psychological tests and, as a result, can be applied in scientific research. The final version of the questionnaire consists of 32 items (including 31 diagnostic ones) that make up five dimensions of attitudes toward death: (a) Fear of Death, (b) Death Avoidance, (c) Neutral Acceptance, (d) Escape Acceptance, and (e) Approach Acceptance...

It is well-known that substrate surface properties have a profound impact on the morphology of thin films solution coated atop and the resulting solid-state properties. However, design rules for guiding the substrate selection have not yet been established. Such design rules are particularly important for solution-coated semiconducting polymers, as the substrate-directed thin film morphology can impact charge transport properties by orders of magnitude. We hypothesize that substrate surface energies dictate the thin film morphology by modulating the free energy barrier to heterogeneous nucleation...

We introduce monotitanium-based endohedral metallofullerenes (EMFs) using density functional theory calculations. Isomeric C64 fullerenes are initially employed as hosts, and Ti@C64 species show novel features on the electronic structures. Energetically, the preference of titanium residing on triple-fused-pentagon subunits is proposed in theory. More importantly, different from current knowledge on mono-EMFs, electron transfer between titanium and carbon cages is not unified but is essentially dependent on the pentagon distribution of the binding sites, giving rise to variations of the cationic titanium of Ti@C64 ...

STUDY DESIGN: Meta-analysis. OBJECTIVES: Although the association between modifiable psychosocial factors and spinal cord injury (SCI) pain has been identified, the full range of psychological and social difficulties for those who experience acute and/or persistent pain remains unclear. This meta-analysis consolidates the available evidence, using the International Classification of Functioning, Disability and Health (ICF) as a reference framework. METHODS: Nineteen studies that examined persistent neuropathic, nociceptive or mixed pain subtypes in adults with a SCI (newly acquired and chronic; Nparticipants=2934) were identified from electronic database searches...

Collagen fibrils type I display a typical banding pattern, so-called D-periodicity, of about 67 nm, when visualized by atomic force or electron microscopy imaging. Herein we report on a significant shortening of the D-period for human corneal collagen fibrils type I (21 ± 4 nm) upon air-drying, whereas no changes in the D-period were observed for human scleral collagen fibrils type I (64 ± 4 nm) measured under the same experimental conditions as the cornea. It was also found that for the corneal stroma fixed with glutaraldehyde and air-dried, the collagen fibrils show the commonly accepted D-period of 61 ± 8 nm...

The cellular translational machinery (TM) synthesizes proteins using exclusively L- or achiral aminoacyl-tRNAs (aa-tRNAs), despite the presence of D-amino acids in nature and their ability to be aminoacylated onto tRNAs by aa-tRNA synthetases. The ubiquity of L-amino acids in proteins has led to the hypothesis that D-amino acids are not substrates for the TM. Supporting this view, protein engineering efforts to incorporate D-amino acids into proteins using the TM have thus far been unsuccessful. Nonetheless, a mechanistic understanding of why D-aa-tRNAs are poor substrates for the TM is lacking...

OBJECTIVES: Self-affirmation (induced by reflecting upon important values, attributes, or social relations) appears to reduce defensive resistance to health-risk information and increase subsequent readiness for health behavior change. However, these effects of self-affirmation have yet to be subjected to formal, quantitative integration. Consequently, the current article reports a meta-analysis of the impact of self-affirmation on outcomes at 3 key points in the process of health-behavior change: (a) message acceptance, (b) intentions to change, and (c) subsequent behavior...

Lysine 5,6-aminomutase (5,6-LAM) and ornithine 4,5-aminomutase (4,5-OAM) are two of the rare enzymes that use assistance of two vitamins as cofactors. These enzymes employ radical generating capability of coenzyme B12 (5'-deoxyadenosylcobalamin, dAdoCbl) and ability of pyridoxal-5'-phosphate (PLP, vitamin B6) to stabilize high-energy intermediates for performing challenging 1,2-amino rearrangements between adjacent carbons. A large-scale domain movement is required for interconversion between the catalytically inactive open form and the catalytically active closed form...

The photophysical and electrochemical properties of four novel donor-accepter (D-A) conjugated oligomers a-d based on 3,4-ethylenedioxythiophene (EDOT) and electrondeficient heterocycle rings were investigated. The UV-vis absorption spectroscopy, fluorescence emission spectroscopy and cyclic voltammertry studies suggest that the oligomers are expected to provide enhanced charge-transporting properties for the development of efficient electroluminescent materials. Furthermore, the third-order nonlinear optical (NLO) measurements made by Z-scan technique indicate that they have good third-order NLO response and are desired materias for fabricating nonlinear photonic devices...
