A method to determine the time course of ethanol concentration in the brains of rats during operant ethanol self-administration is described. Gas chromatography with flame ionization detection is used to quantify ethanol in the dialysate samples, because it has the sensitivity required for the small volumes that are generated.

We present protocols to be used in the measurement of spray droplet size from agricultural nozzles used in both aerial and ground based agrochemical applications. These methods presented were developed to provide consistent and repeatable droplet size data both inter- and intra-laboratory, when using laser diffraction systems.

Biofuels: Producing Ethanol from Cellulosic Material

2023
Source: Laboratories of Margaret Workman and Kimberly Frye - Depaul University In this experiment, cellulosic material (such as corn stalks, leaves, grasses, etc.) will be used as a feedstock for the production of ethanol. The cellulosic material is first pretreated (ground and heated), digested with enzymes, and then fermented with yeast. Ethanol production is monitored using an ethanol probe. The experiment can be extended to optimize ethanol production by varying the feedstock used,...

Topical Airway Anesthesia for Awake-endoscopic Intubation Using the Spray-as-you-go Technique with High Oxygen Flow

2017
The topical anesthetic lidocaine was atomized using a high oxygen flow through the working channel of a flexible intubating endoscope to achieve topical airway anesthesia for awake endotracheal intubation. We prefer this modified spray-as-you-go technique for endoscopic intubation to classical bolus application because of higher patient satisfaction and better compliance.
FAQs
The antimicrobial effect depends on whether the formulation reaches an effective ethanol concentration and remains in contact with the target long enough to act. If ethanol evaporates before adequate contact occurs, microbial reduction may be limited. Application should therefore follow the product instructions for concentration, coverage, and contact time rather than relying on spraying alone.
Ethanol can penetrate microbial cells, disrupt lipid membranes, and denature proteins. These changes interfere with the structural and functional components needed for cellular integrity. The combined effects explain why ethanol-based formulations can reduce microbial contamination on suitable skin or surface targets when the spray provides adequate coverage and contact.
Fine droplets must reach the relevant target area for the formulation to work consistently. Uneven coverage can leave untreated portions, while rapid evaporation can shorten contact time. These factors make the way a spray is distributed clinically important, especially when preparing skin or surfaces where missed areas could reduce overall antimicrobial performance.
Before application, identify the intended target and follow the product instructions for coverage and contact time. Confirm that the formulation is appropriate for topical skin, a surface, or another stated use. After spraying, the treated area must receive the specified exposure needed for antimicrobial action, rather than being evaluated only by how quickly it dries.
Ethanol spray is flammable, so handling and storage should account for that hazard. It may also irritate damaged skin or mucous membranes, making the intended application site important. Medical users should avoid treating unsuitable areas and follow product directions, particularly when the skin barrier is compromised or contact with mucous membranes is possible.
In medicine, ethanol spray may support hand and skin hygiene, prepare surfaces before procedures, or help control transmission of infectious agents. Its value depends on appropriate formulation and application, including sufficient coverage and contact time. These uses address microbial contamination at different points in care, so the selected product should match the intended target.
