Sonication

Entropic repulsion caused by interfacial orientational fluctuations of cholesterol layers restricts protein adsorption and bacterial adhesion, providing a conceptually new physicochemical perspective on biointerfaces that may guide future material design in regulation of adhesion.

Abstract: Nanoparticle dispersions at a minute concentration in salt mixtures have recently been reported to significantly increase their specific heat capacity. However, there is a discrepancy between experimental results reported for the same kind of molten salt-nanoparticle mixtures by different research groups. From our literature survey, we learned that there is no standardized synthesis protocol […]

From electrical fields to ultrasound waves, the growing science of brain stimulation could launch a new era of meditation research. It might move us beyond self-care, stress, and depression.

A "sonication" time between 1 and 3 minutes is ideal to get the perfect cold brew.

Vaterite is one of the three forms of calcium carbonate, along with calcite and aragonite. Nanosized vaterite is valuable for various applications, such as drug delivery, cosmetics, and bone defect filling, owing to its biocompatibility, high porosity, solubility, and large specific surface area.

Liquid metals (LM) such as pure gallium (Ga) and Ga-based alloys are a new class of materials with unique physicochemical properties. One of the most prominent applications of LMs is photothermal therapy against cancer, in which functional LM nanoparticles convert light energy to heat energy, thus killing cancerous cells. LM-based phototherapy is superior to traditional cancer therapy owing to its high specificity,…

Since the International Organization of Vine and Wine (OIV) approved the use of ultrasound to promote the extraction of grape compounds back in 2019, its application for obtaining superior red wines has been studied extensively.

Magnesium diboride (MgB2) is a low-cost, non-toxic superconductor used in field magnets, electric motors, and generators. However, producing nanoscale boron (B) particles to fabricate MgB2 is expensive. Researchers recently tackled this issue by using high-energy ultra-sonication in 2-propanol, a highly viscous solvent, to produce impurity-free, nm-sized B particles. The approach is cost-effective and enables…

IL-2 cytokine therapy is made safer by splitting a designed mimetic in two for tumor targeting.

The SARS-CoV-2 protein ORF8 functions as a mimic of histone H3 to disrupt host cell epigenetic regulation.

There is an emerging need for noninvasive neuromodulation techniques to improve patient outcomes while minimizing adverse events and morbidity. Low-in…

An interdisciplinary team of researchers at the University of Alabama at Birmingham have developed a new plasma-enabled process that could limit the proliferation of toxins from implants into a patient's bloodstream. The team, led by Vinoy Thomas, Ph.D., associate professor in the UAB School of Engineering's Department of Mechanical and Materials Engineering, recently published findings in the ACS Applied Materials…

Baker Heart and Diabetes Institute researchers have designed and developed a novel drug delivery method that can vastly improve the efficacy of a drug used to treat atherosclerosis and has the potential to identify and treat other diseases.

Over in the Potency department, it is the cannabis chemist's job to accurately determine the cannabinoid profile of any sample that enters the laboratory. Let's break down how cannabis laboratories do this from beginning to end to help you understand the process

Ammonia is commonly used in fertilizer because it has the highest nitrogen content of commercial fertilizers, making it essential for crop production. However, two carbon dioxide molecules are made for every molecule of ammonia produced, contributing to excess carbon dioxide in the atmosphere.

In groundbreaking experiments, carbothermal reduction fuels new possibilities for sustaining life and fueling spacecraft far from Earth.

A study published in the journal of Engineering reveals a remarkable development in the field of green coating materials for leather. Researchers have successfully synthesized a solvent-free, bio-based antibacterial agent and aromatic monomer called methacrylated vanillin (MV). This innovative compound not only imparts antibacterial properties to leather coatings but also serves as an eco-friendly alternative to…

Liquid metal, planet-like nanodroplets have been successfully formed with a new technique developed at RMIT University, Australia. Like our own planet Earth, the nanodroplets feature an outer "crust," a liquid metal "mantle," and a solid "core."

A team of researchers has developed a new method for exfoliating MoS2 flakes that produces very large and very thin flakes with high yield. The microwave-assisted exfoliation yields 50 times more flakes than those obtained by ultrasonication and gives a material quality comparable to mechanical exfoliation. This fast process requires minimal processing and holds promise to enable new applications in electronic and…

Using a high-quality chromosome-scale assembly of the faba bean genome, the genetic basis of seed size and hilum colour is explored.
