FUNCTIONALIZED CROWN ETHERS FOR LITHIUM-ION BATTERIES
An electrolyte containing functionalized crown ethers suitable for use in electrochemical energy storage devices useful for reducing battery resistance, increasing cycle life, and improving high-temperature performance is disclosed.
Access to chiral bisphenol (BPOL) ligands through desymmetrizing asymmetric ortho-selective mono-halogenation
The subject invention pertains to a method of halogenating phenols, yielding a range of halogenated phenols with enantiomeric ratio of up to 99.5:0.5. In certain embodiments, the subject invention pertains to a method of asymmetric halogenation of bisphenol, yielding a range of chiral bisphenol ligands. The novel chiral bisphenols are potent privileged catalyst cores that can be applied to the preparation of ligands for various catalytic asymmetric reactions. The catalyst library can easily be accessed because late-stage modification of the scaffold can readily be executed through cross-coupling of the halogen handles on the bisphenols.

SELECTIVE DETECTION OF BED BUGS
A device, system, and method of controlling pests are disclosed. A pest control device includes a sensor having a sensor cell and a controller. A surface of the sensor cell is coated with an agent that reacts with a targeted biochemical analyte secreted by pests. The controller is coupled to the sensor and is configured to receive sensor data from the sensor cell indicative of a rate of change in sensor mass detected on the surface of the sensor cell, determine whether the rate of change in the sensor mass based on the received sensor data exceeds a predefined threshold rate, and transmit a pest detection alert notification to a server in response to a determination that the rate of change exceeds the predetermined threshold rate.

Selective detection of bed bugs
A chemical agent useful for controlling pests is disclosed. The agent can be a thiol, such as a cyclic thiol according to Formula I. The agent can be used to react with a targeted biochemical analyte secreted by pests, such as bed bugs, to provide an adduct. The agent can be useful in a pest control device, system, or method for detecting pests, which can involve use of a controller and a sensor cell coated with composition containing the agent. The disclosure also describes the adduct obtained from the agent and the analyte, as well as a composition containing the agent or adduct. ##STR00001##
