A new method that makes use of monomolecular patches on a liquid surface has been developed for the crystallization of single chain, and single-chain single crystals of poly(ethylene-oxide) and isotactic polystyrene were investigated. The molecular mass and molecular mass distribution of samples could be found to match a statistical analysis of single ...

Single-Layer Single-Crystalline SnSe Nanosheets
Journal of the American Chemical Society, 2013Single-layer single-crystalline SnSe nanosheet with four-atomic thickness of ~1.0 nm and lateral size of ~300 nm is presented here by using a one-pot synthetic method. It is found that 1,10-phenanthroline plays an important role in determining the morphology of the SnSe product as three-dimensional SnSe nanoflowers are obtained in the absence of 1,10 ...

The increasing use of single use medical devices is being driven by a growing awareness of iatrogenic (from the Greek; caused by the doctor) and nosocomial infections. Public health perceptions relating to transmissible spongiform encephalopathies, specifically variant Creutzfeldt-Jakob disease (vCJD), the Human Immunodeficiency Virus (HIV) and ...

Pragmatics and Society
Abstract This EMCA (Ethnomethodology and Conversation Analysis) study concerns carers’ multimodal methods for including residents living with dementia in social activities in remote locations. It illustrates how groups of residents are pre-arranged and how the residents are subsequently singled out one by one through requests to come ...

Single-passband, single-stopband narrowband filters
2000 IEEE MTT-S International Microwave Symposium Digest (Cat. No.00CH37017), 2000Techniques are presented for obtaining an optimum filter response for narrow-band requirements of a single passband and a single stopband. For certain transformed equiripple passband responses, including Chebyshev and elliptic function responses and a new "double n/2 poles" response, the minimum number of resonators can be easily determined, resulting ...

Confined Nanopipette Sensing: From Single Molecules, Single Nanoparticles, to Single Cells
Angewandte Chemie International Edition, 2018AbstractNanopipettes provide a promising confined space that enables advances in electrochemical, optical, and mass spectrometric measurements at the nanoscale. They have been employed to reveal the hidden population properties and dynamics of single molecules and single particles.
