Data archive for "Chemically fueled transient geometry changes in diphenic acids"
Transient changes in molecular geometry are key to the function of many important biochemical systems. Here, we show that diphenic acids undergo out-of-equilibrium changes in dihedral angle when reacted with a carbodiimide ... -
Data archive for "Conformational control of ortho-phenylenes by terminal amides"
Control over the folding of oligomers, be it broad induction of a preferred helical handedness or subtle changes in the orientations of individual functional groups, is important for applications ranging from molecular ... -
Data archive for "Dissipative assembly of macrocycles comprising multiple transient bonds"
Dissipative (nonequilibrium) assembly powered by chemical fuels has great potential for the creation of new adaptive chemical systems. However, while molecular assembly at equilibrium is routinely used to prepare complex ... -
Data archive for "Engineering chiral induction in centrally functionalized ortho-phenylenes"
Work on foldamers, non-biological oligomers that mimic the hierarchical structure of biomacromolecules, continues to yield new architectures of ever increasing complexity. o-Phenylenes, a class of helical aromatic foldamers, ... -
Data archive for "Fluorine Labeling of ortho-Phenylenes to Facilitate Conformational Analysis"
1H NMR spectroscopy is a powerful tool for the conformational analysis of ortho-phenylene foldamers in solution. However, as o-phenylenes are integrated into ever more complex systems, we are reaching the limits of what ... -
Data archive for "Folding-controlled assembly of ortho-phenylene-based macrocycles"
The self-assembly of foldamers into macrocycles is a simple approach to non-biological higher-order structure. Previous work on the co-assembly of ortho-phenylene foldamers with rod-shaped linkers has shown that folding ... -
Data archive for "Guest-driven control of folding in a crown-ether-functionalized ortho-phenylene"
A crown-ether-functionalized o-phenylene tetramer has been synthesized and coassembled with monotopic and ditopic, achiral and chiral secondary ammonium ion guests. NMR spectroscopy shows that the o-phenylene forms both ... -
Data archive for "Macrocycles of higher ortho-phenylenes: assembly and folding"
Higher-order structure in abiotic foldamer systems represents an important but largely unrealized goal. As one approach to this challenge, covalent assembly can be used to assemble macrocycles with foldamer subunits in ... -
Data archive for "ortho‐Phenylene‐based macrocyclic hydrocarbons assembled using olefin metathesis"
While many foldamer systems reliably fold into well‐defined secondary structures, higher order structure remains a challenge. A simple strategy for the organization of folded subunits in space is to link them together ... -
Data archive for "Structure–property effects in the generation of transient aqueous benzoic acid anhydrides by carbodiimide fuels"
The design of dissipative systems, which operate out-of-equilibrium by consuming chemical fuels, is challenging. As yet, there are a few examples of privileged fuel chemistries that can be broadly applied in abiotic systems ... -
Data archive for "Substituent effects on transient, carbodiimide-induced geometry changes in diphenic acids"
Nucleotide-induced conformational changes in motor proteins are key to many important cell functions. Inspired by this biological behavior, we report a simple chemically fueled system that exhibits carbodiimide-induced ... -
Data archive for "Transient Polymers through Carbodiimide-driven Assembly"
Biochemical systems make use of out-of-equilibrium polymers generated under kinetic control. Inspired by these systems, abiotic supramolecular polymers driven by chemical fuel reactions have recently been reported. Conversely, ... -
Data: Real-Time Bio-Layer Interferometry Ubiquitination Assays as Alternatives to Western Blotting
Ubiquitination is a crucial cellular pathway enabling normal cellular functions such as cell cycle regulation, DNA damage repair, cell signaling, and maintenance of protein homeostasis. However, abnormalities or failures ... -
Degree-constrained Minimum Latency Trees are APX-Hard
(2008-03-25)When transmitting data from a single source to many recipients, it is often desirable to use some recipients of the stream to re-broadcast the stream to other users. In such multicast systems each client may be used as a ... -
A Demonstration of Computer Assisted Instruction Using Authorware Professional to Teach Basic Theology
(1996-12-01)The purpose of this thesis is to investigate principles which are basic to Computer Assisted Instruction and how Authorware Professional is able to make use of these principles. A computer assisted instruction module will ... -
Design and Implementation of a Hypertext-based Information Retrieval System
(1992-08-01)Information Retrieval (IR), which is also known as text or document retrieval, is the process of locating and retrieving documents that are relevant to the user queries. In hypertext environments, document databases are ...
