Federal Employees on Social Media Could Hurt Government Image
The complicated societal and political times that we now live in have resulted in an explosion of social media communications from government employees that can conflict with the mission and image of the employing agency. The rise of “alt” or “rogue” government social media accounts has become a notable development.

An overlooked defense in faculty First Amendment academic freedom and other cases
(January 21, 2025) - Mark Meyerhoff and David Urban of Liebert Cassidy Whitmore discuss the doctrine of claim preclusion as a defense to lawsuits brought by faculty at colleges and universities challenging their termination and raising issues of academic freedom. Terminating tenured faculty can present significant challenges for public colleges and universities.
Ninth Circuit Provides New Guidance For Defining Protected Speech Under the First Amendment And The Permissible Scope Of Social Media Policies
Social media sites have become the new “public square” where individuals share opinions and information about all types of political and societal events. Public sector employees, as much as anyone else, use social media to post viewpoints and to participate in public debate.
Characterization of the Impact of Mixing and Droplet Volumes on the Behavior of Microfluidic Ion-Selective Droptodes
Characterization of the Impact of Mixing and Droplet Volumes on the Behavior of Microfluidic Ion-Selective Droptodes Droplet microfluidic optodes, or “droptodes”, have emerged as a powerful technology for rapid detection of small ions in complex matrices. While using segmented aqueous phases provides the benefits of sample isolation, the influence of the liquid nature of the oil carrier phase has not yet been explored.
Nitric Oxide Release for Enhanced Biocompatibility and Analytical Performance of Implantable Electrochemical Sensors
Review Qi Zhang, University of Michigan, UNITED STATES Search for more papers by this author Mark Meyerhoff, Corresponding Author mmeyerho@umich.edu University of Michigan, UNITED STATES Search for more papers by this author PDF ShareShare Abstract In this review, the physiological functions of NO to improve the biocompatibility of implantable electrochemical sensors are introduced, followed by a brief analysis of chemical approaches to realize NO release from such devices.
Plasticizer-free and pH-independent ion-selective optode films based on a solvatochromic dye
Plasticizer-free and pH-independent ion-selective optode films based on a solvatochromic dye A layer of a solvatochromic dye, an ionophore, and an ion-exchanger deposited on a Nylon membrane enables highly selective colorimetric and fluorometric ion sensing. This new platform does not suffer from interference from the sample pH and does not require a plasticizer to dissolve the sensing chemicals.

Synthesis and Characterization of a Fluorinated S-Nitrosothiol as the Nitric Oxide Donor for Fluoropolymer-Based Biomedical Device Applications
Fluorinated polymers are widely used as biomaterials in various biomedical implant and device applications. However, thrombogenicity, surface-induced inflammation, and risk of microbial infection remain key issues that can limit their use. In this work, we describe the first nitric oxide (NO) releasing fluorinated polymer, in which a new fluorinated NO donor, S-nitroso-N-pentafluoropropionylpenicillamine (C F -SNAP), is incorporated within the polyvinylidene fluoride (PVDF) tubing.
Detecting Levels of Polyquaternium-10 (PQ-10) via Potentiometric Titration with Dextran Sulphate and Monitoring the Equivalence Point with a Polymeric Membrane-Based Polyion Sensor - Analytical Methods (RSC Publishing)
Polymeric quaternary ammonium salts (polyquaterniums) have found increasing use in industrial and cosmetic applications in recent years. More specifically, polyquaternium-10 (PQ-10) is routinely used in cosmetic applications as a conditioner in personal care product formulations. Herein, we demonstrate the use of potentiometric polyion-sensitive polymeric membrane-based electrodes to quantify PQ-10 levels.
