We report the synthesis and optoelectronic properties of TIPS-peri-pentacenopentacene (TIPS-PPP), a vertical extension TIPS-pentacene (TIPS-PEN) low-band-gap material with remarkable stability. found synthetic conditions to avoid competition between 1,2- 1,4-addition lithium acetylide on large aromatic dione. The high stability TIPS-PPP is due peri-fusion which increases aromaticity by generati...

This paper demonstrates the sectioning of chemically synthesized, single-crystalline microplates of gold with an ultramicrotome (nanoskiving) to produce single-crystalline nanowires; these nanowires act as low-loss surface plasmon resonators. This method produces collinearly aligned nanostructures with small, regular changes in dimension with each consecutive cross-section: a single microplate ...

Controlled modification of appropriate sharpness for nanotips is of paramount importance to develop novel materials and functional devices at a nanometer resolution. Herein, we present a reliable and unique strategy of laser irradiation enhanced physicochemical etching to manufacture super sharp tungsten tips with reproducible shape and dimension as well as high yields (~80%). The corresponding...

Potentiometric pH selective tips for scanning electrochemical microscopy (SECM) have been developed and used to image local pH changes in a variety of model chemical systems. Images of pH profiles around a platinum microelectrode during water reduction, a corroding disk of silver iodide in aqueous potassium cyanide, a disk of immobilized urease hydrolyzing urea, and a disk of immobilized yeast ...

BACKGROUND The teaching of humanistic values is recognized as an essential component of medical education and continuing professional development of physicians. The application of humanistic values in medical care can benefit medical students, clinicians and patients. AIMS This article presents 12 tips on fostering humanistic values in medical education. METHOD The authors reviewed the lite...

Aqueous nanoparticle (NP) dispersions are commonly used as model systems for spectro- scopic study of singlet exciton fission (SF) in acenes such 6,13-(triisopropylsilylethynyl) pentacene (TIPS-Pn). However, the potential particle size effects to complicate interpretation results is generally ignored. In this work, we amorphous TIPS-Pn NP prepared by re-precipitation method over a range sizes. ...

research misconduct is not a new problem in the research field. however, in recent years, the researchers themselves could be a victim of a newly expanded trouble: being hijacked by email. being obsessive about publishing one’s research results and finding the “real journals” seems not to be enough in recent years. in this article we will have a closer look to this issue and discuss two real ex...

BACKGROUND Tissue microarray technology has provided a high throughput means of evaluating potential biomarkers in archival pathological specimens. This study was carried out in order to produce tissue microarray blocks using mechanical pencil tips without high cost. METHOD Conventional mechanical pencil tips (Rotring Tikky II Mechanical Pencil 1.0 mm) were used to cut out 1 mm wax cylinders ...
