Article Synopsis

  • Surfaces contaminated with pathogens significantly threaten global public health and current disinfection methods either act quickly but are not long-lasting or are enduring but slow to work.
  • Research introduces new antimicrobial surfaces using plant secondary metabolites that can quickly disinfect a wide range of pathogens while maintaining effectiveness for months, even in harsh conditions.
  • These innovative surfaces can be easily applied to various materials using simple techniques like spray or brush coating.

Article Abstract

Surfaces contaminated with bacteria and viruses contribute to the transmission of infectious diseases and pose a significant threat to global public health. Modern day disinfection either relies on fast-acting (>3-log reduction within a few minutes), yet impermanent, liquid-, vapor-, or radiation-based disinfection techniques, or long-lasting, but slower-acting, passive antimicrobial surfaces based on heavy metal surfaces, or metallic nanoparticles. There is currently no surface that provides instant and persistent antimicrobial efficacy against a broad spectrum of bacteria and viruses. In this work, we describe a class of extremely durable antimicrobial surfaces incorporating different plant secondary metabolites that are capable of rapid disinfection (>4-log reduction) of current and emerging pathogens within minutes, while maintaining persistent efficacy over several months and under significant environmental duress. We also show that these surfaces can be readily applied onto a variety of desired substrates or devices via simple application techniques such as spray, flow, or brush coating.

Per- and polyfluoroalkyl substances (PFASs) are environmentally persistent, bioaccumulative, and toxic chemicals that contaminate global drinking water resources. Their ubiquity and potential impact on human health motivate large-scale remediation. Conventional materials used to remove PFASs during drinking water production are functionally inefficient or energetically expensive, motivating the discovery of new materials and technologies.

Quasi-exact dynamic average consensus under asynchronous communication and symmetric delays.

ISA Trans

August 2025

Departamento de Informatica e Ingenieria de Sistemas (DIIS) and Instituto de Investigacion en Ingenieria de Aragon (I3A), Universidad de Zaragoza, C. María de Luna, 50018, Zaragoza, Spain. Electronic address:

This work focuses on the problem of dynamic average consensus, which involves computing the average of a set of time-varying reference signals spread across a network in a distributed fashion. To make this problem more applicable to realistic scenarios, we consider agents in the network that can only communicate at asynchronous discrete-time instants and are subject to time-varying symmetric edge-wise delays. Our proposal is based on high-order sliding modes.

Water-Resistant Supramolecular Eutectogel Lubricant with MoS: Thixotropic Behavior and High-Efficiency Lubrication.

ACS Appl Mater Interfaces

August 2025

Key Laboratory of Applied Surface and Colloid Chemistry of Ministry of Education, Shaanxi Key Laboratory of New Concept Sensors and Molecular Materials, School of Chemistry and Chemical Engineering, Shaanxi Normal University, Xi'an 710119, China.

The development of supramolecular gel lubricants with excellent rheological properties is critical for high-performance lubrication. Although hydrophobic deep eutectic solvents (HDESs) have shown considerable potential as lubricants, eutectogels containing HDESs remain largely unexplored. Herein, we report the first water-resistant supramolecular eutectogel based on HDES, exhibiting an outstanding thixotropic behavior and lubrication performance.

A Novel Hypnotic Intervention for the Treatment of Ornithophobia. A Case Study.

Int J Clin Exp Hypn

August 2025

Department of Research, Centro Provinciale Istruzione Adulti Salerno Paulo Freire, Salerno (SA), Italy.

This case study explores the successful treatment of severe ornithophobia in a 25-year-old woman, referred to as Emma, through a novel hypnotic intervention that integrates mindfulness and autogenic training. Emma's chronic fear of pigeons had significantly impacted her professional life. The Severity Measure for Specific Phobia-Adult (SMSP-A) was used to assess her level of phobia pre- and post-intervention, as well as at a 6-month follow-up.
