Recently, highly efficient solar cells based on organic-inorganic perovskites have been intensively reported for developing fabricating methods and device structures. Additional power conversion efficiency should be gained without increasing the thickness and the complexity of the devices to accord with practical applications. In this paper, a rough interface between perovskite and HTM was fabr...

Various polybenzimidazole (PBI)-based ion-exchange films were prepared and thoroughly characterized by Fourier transform infrared (FT-IR) spectroscopy, proton conductivity, and water uptake for possible use as fuel cell membranes. Upon the increase in the flexibility of the PBI-based polymer films (e.g., poly(oxyphenylene benzimidazole) (OPBI) and sulfonated OPBI (s-OPBI)), the membranes exhibi...

In well-selected patients who choose to pursue breast conservation therapy (BCT) for early-stage breast cancer, partial breast irradiation (PBI) delivered externally or intraoperatively, may be a viable alternative to conventional whole breast irradiation. Two large, contemporary randomized trials have demonstrated breast intraoperative radiotherapy (IORT) to be noninferior to whole breast exte...

on thyroxine-binding proteins (UTBP), T4 bound to thyroxine-binding proteins (PBI or TBPT4) andfree thyroxine (FT4). thyroid status. This is shown in diagrammatic fashion in fig 1 which illustrates the changes that occur in thyrotoxicosis and hypothyroidism and in those situations where there are alterations in thyroxine-binding protein capacity, such as the increase in thyroxine-binding globul...

Arthritogenicity, as determined by joint swelling and synovial histology, was compared between or within two Borrelia genospecies that cause Lyme arthritis in humans. The spirochete burden in bladder tissue (a site of spirochete persistence) was documented by quantitative polymerase chain reaction, and immune responses were analyzed. In C3H/HeJ mice, three B. burgdorferi isolates and two of the...

The currently available PEMs are suitable for use at maximum 80C because of the requirement of the presence of water for proton conductivity. However, for emerging applications, a fuel cell operating at temperatures as high as 120 C is required. This can possibly be achieved by creating novel PEMs. Supramolecular polymers are being investigated extensively and may be conjugated with heteropolya...

OBJECTIVE The goal of this study was to contrast the childhood environment of adult psychiatric outpatients reporting to have been bullied at school with those who were not. METHOD One-hundred-sixty consecutive adult outpatients from a psychiatric clinic in Norway completed self-administered questionnaires about their psychosocial environment during childhood and adolescence. The frequency of...

A method for the determination of serum protein-bound iodine (PBI) is presented. Chioric acid digestion is carried out in a single tube as described by other authors. In order to shorten the period when close supervision is necessary, the digestion process has been reduced to 1 hour and the estimation completed within 4 hours. The method has been modified to make it a more manageable routine pr...

Spectrally resolved photoluminescence is used to measure the band-to-band absorption coefficient α(BB)(ℏω) of organic-inorganic hybrid perovskite methylammonium lead iodide (CH₃NH₃PbI₃) films from 675 to 1400 nm. Unlike other methods used to extract the absorption coefficient, photoluminescence is only affected by band-to-band absorption and is capable of detecting absorption events at very low...
