Miniature Nanomesh Mechano‐Acoustic Sensor with Wide Linear Dynamic Range, Broad Bandwidth, and Flat Frequency Response

Advanced Functional Materials, EarlyView.
A miniaturized mechano‐acoustic sensor is developed using an electrospun PVDF nanomesh as the diaphragm in a capacitive sensor structure. Unlike conventional nanomesh‐based sensors, it achieves high linear sensitivity, a broad and flat frequency response, and a compact form factor.

Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

Advanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

Multicolor Optoelectronic Synapse Enabled by Photon‐Modulated Remote Doping in Solution‐Processed Van Der Waals Heterostructures

Advanced Functional Materials, EarlyView.
Multicolor optoelectronic synapses are realized by vertically integrating solution‐processed MoS2 thin‐film and SWCNT. The electronically disconnected but interactive MoS2 enables photon‐modulated remote doping, producing a bi‐directional photoresponse.

Complex Cryptographic and User‐Centric Physically Unclonable Functions Enabled by Strain‐Sensitive Nanocrystals via Selective Ligand Exchange

Advanced Functional Materials, EarlyView.
This study investigates electromechanical PUFs that improve on traditional electric PUFs. The electron transport materials are coated randomly through selective ligand exchange. It produces multiple keys and a key with motion dependent on percolation and strain, and approaches almost ideal inter‐ and intra‐hamming distances.

Chemical reaction networks

IEEE Transactions on Circuits and Systems, 1974
A set of chemical species "interconnected" by reaction pathways is commonly referred to as a chemical network. We show that chemical networks are mathematically equivalent to a class of multiport networks. Hence, abstract circuit theory can be applied to study chemical systems.

RELEVANT CYCLES IN CHEMICAL REACTION NETWORKS [PDF]

Advances in Complex Systems, 2001
We characterize the distributions of short cycles in a large metabolic network previously shown to have small world characteristics and a power law degree distribution. Compared with three classes of random networks, including Erdős–Rényi random graphs and synthetic small world networks of the same connectivity, both the metabolic network and models ...

DNA‐Based Chemical Reaction Networks

ChemBioChem, 2019
AbstractMotivated by complex molecular networks of biological organisms, which enable control of the temporal and spatial concentrations of molecules, the bottom‐up development of artificial chemical reaction networks has received renewed interest from biochemists.

Chemical reaction network sensitivity analysis

The Journal of Chemical Physics, 1984
Traditional sensitivity analysis of a chemical reaction system’s periodic trajectory shows how the oscillation depends on the reaction rate constants. We develop sensitivity analysis within the framework of a stoichiometric network analysis, which is a theory that relates the dynamics of complex chemical reaction systems to feedback loops in the ...

Embracing Noise in Chemical Reaction Networks

Bulletin of Mathematical Biology, 2019
We provide a short review of stochastic modeling in chemical reaction networks for mathematical and quantitative biologists. We use as case studies two publications appearing in this issue of the Bulletin, on the modeling of quasi-steady-state approximations and cell polarity.

Reconstructing chemical reaction networks

Proceedings of the 14th ACM SIGKDD international conference on Knowledge discovery and data mining, 2008
We present an approach to reconstructing chemical reaction networks from time series measurements of the concentrations of the molecules involved. Our solution strategy combines techniques from numerical sensitivity analysis and probabilistic graphical models.
