Synaptic and Circuit Mechanisms Governing Corollary Discharge in the Mouse Auditory Cortex
(2015)Auditory sensations can arise from objects in our environment or from our own actions, such as when we speak or make music. We must able to distinguish such sources of sounds, as well as form new associations between our ... -
Syntax of Phase Transition Peptide Polymers with LCST and UCST Behavior
(2013)"Smart" polymers that sense stimuli in aqueous environments and that respond with a pronounced change in their solvation are of great utility in biotechnology and medicine. Currently, however, only few peptide polymers are ... -
Synthesis and Mechanistic Study of Carbon Nanotubes and Tungsten Oxide Nanowires by Chemical Vapor Deposition Methods
(2007-09-28)Chemical vapor deposition (CVD) is a versatile method for material preparation. Materials from films to nanostructures can be obtained by tuning the parameters of the CVD method. In the field of one-dimensional nanostructures, ... -
Synthesis and Properties of GaAs1-xBix Prepared by Molecular Beam Epitaxy
(2016)GaAs1-xBix is a III-V semiconductor alloy which has generated much fundamental scientific interest. In addition, the alloy possesses numerous device-relevant beneficial characteristics. However, the synthesis of this material ... -
Synthesis and Self-assembly of Amphiphilic DNA Copolymers
(2018)The unique structural and chemical properties of DNA enable it as a polymeric building material in bionanotechnology. Conjugating hydrophobic moieties to DNA chains makes DNA amphiphiles that can self-assemble into various ... -
Synthesis of Protected Amines from Azadiene and Azaallyl Anion Building Blocks
(2018)Amines are ubiquitous in medicinal compounds and essential to human health. We have addressed the limitations of amine synthesis by significantly expanding the utility of 2-azaallyl anions and 2-azaallyl anion-like reagents ... -
