Graphene is two-dimensional nanomaterial consisting of a single layer of sp2 network of carbon atoms (Fig. 1a)1. While the thickness of a graphene sheet is on the order of a single atomic unit, its lateral dimension can approach up to tens of microns. Graphene and its derivatives such as graphene oxide (GO) (Fig. 1b), and reduced graphene oxide (r-GO, a.k.a. chemically modified graphene) (Fig. ...

The purpose of a Safety Data Sheet (SDS), formerly known as Material Safety Data Sheets (MSDS), is to provide information on the hazards of working with a chemical and procedures that should be used to ensure safety. State and Federal law require that employers obtain an SDS for each hazardous substance they use or store and make the SDS available to employees. The PI/instructor is responsible ...

Newborn screening fact sheets were last revised in 1996 by the American Academy of Pediatrics Committee on Genetics. This revision was prompted by advances in the field since 1996, including technologic innovations, as well as greater appreciation of ethical issues such as those surrounding informed consent. The following disorders are discussed in this revision of the newborn screening fact sh...

We are, or at least most of us are, librarians. We tend collections that are still mostly made up of physical items on a series of shelves (for the purposes of this discussion, I am considering physical journals, bound or unbound, to be books. Humor me, please). Some of our collections are reaching a tipping point where the electronic resources we have will outweigh (intellectually, at least) t...

PURPOSE To study the feasibility of engineering conjunctival epithelial cell sheets on a temperature-responsive culture dish for ocular surface reconstruction. METHODS Rabbit conjunctival epithelial cells (rCjECs) were cultured in DMEM/F-12 (1:1) medium. The morphology and phenotype of the rCjECs were confirmed with phalloidin staining, periodic acid-Schiff (PAS) staining, and immunocytochemi...

To determine the effect of adipose-derived stem cells (ADSCs) added to bone marrow-derived mesenchymal stem cell (MSC) sheets on bone formation at an ectopic site. We isolated MSCs and ADSCs from the same rabbits. We then prepared MSC sheets for implantation with or without ADSCs subcutaneously in the backs of severe combined immunodeficiency (SCID) mice. We assessed bone formation at eight wee...

Intangible assets are a very economically significant asset class yet are largely excluded by accounting conventions from corporate balance sheets. Ownership (or control) of intangible assets can allow firms to differentiate their offerings to customers and establish some degree of competitive advantage. However, intangibles do not, apart from a few cases of licensing, generate value on their o...

While the effectiveness of one-on-one human tutoring has been well established, a great deal of controversy surrounds the issue of which features of tutorial dialogue separate effective uses of dialogue in tutoring from those that are less effective. In this paper we present a formal comparison of Socratic versus Didactic style tutoring that argues in favor of the Socratic tutoring style.
