Reduced Sliding Friction of Lubricant-Impregnated Catheters.

Journal Article ACS omega · January 2024 During urethral catheterization, sliding friction can cause discomfort and even hemorrhaging. In this report, we use a lubricant-impregnated polydimethylsiloxane coating to reduce the sliding friction of a catheter. Using a pig urethra attached to a microf ... Full text Cite

Post-Pandemic: Investigation of the Degradation of Various Commercial Masks in the Marine Environment.

Journal Article Langmuir : the ACS journal of surfaces and colloids · August 2023 During COVID-19, personal protective equipment such as face masks was in urgent demand in the daily life. As the pandemic may have withdrawn from public attention, the disposal of face masks is a significant issue, especially plastic pollution. To address ... Full text Cite

A SARS-CoV-2 and influenza double hit vaccine based on RBD-conjugated inactivated influenza A virus

Journal Article Science Advances · June 23, 2023 The circulating flu viruses merging with the ongoing COVID-19 pandemic raises a more severe threat that promotes the infectivity of SARS-CoV-2 associated with higher mortality rates. Here, we conjugated recombinant receptor binding domain (RBD) of ... Full text Cite

Gecko-Inspired Adhesives with Asymmetrically Tilting-Oriented Micropillars.

Journal Article Langmuir : the ACS journal of surfaces and colloids · July 2022 The anisotropic adhesion behavior of the gecko is closely related to their feet and is comprised of keratinous hairs, setae, where van der Waals forces permit attachment and detachment during locomotion. Previous research either achieved only isotropic adh ... Full text Cite

Recent Advances in Water Harvesting: A Review of Materials, Devices and Applications

Journal Article Sustainability (Switzerland) · May 1, 2022 Water is essential for life. However, water scarcity is becoming one of the most severe issues worldwide in terms of its potential impacts. There are diverse forms of water on earth and water harvesting from them is quite feasible to access more fresh wate ... Full text Cite

Harps Enable Water Harvesting under Light Fog Conditions

Journal Article Advanced Sustainable Systems · June 2020 AbstractFog harvesting is useful for passively collecting fresh water in arid regions, but the efficiency of current mesh‐based harvesters is compromised by their poor drainage. Inspired by the linear needles of redwood tre ... Full text Cite

Passive water ascent in a tall, scalable synthetic tree

Journal Article Scientific Reports · January 14, 2020 AbstractThe transpiration cycle in trees is powered by a negative water potential generated within the leaves, which pumps water up a dense array of xylem conduits. Synthetic trees can mimic this transpiration cycle, but ha ... Full text Cite
