We present a technique to achieve low-velocity to intermediate-velocity collisions between fragile dust aggregates in the laboratory. For this purpose, two vacuum drop-tower setups have been developed that allow collision velocities between <0.01 and ~10 m/sec. The collision events are recorded by high-speed imaging.

Dust charging and mobilization is demonstrated in three experiments with exposure to thermal plasma with beam electrons, beam electrons only, or ultraviolet (UV) radiation only. These experiments present the advanced understanding of electrostatic dust transport and its role in shaping the surfaces of airless planetary bodies.

Zebrafish are emerging as a valuable model of dietary lipid processing and metabolic disease. Described are protocols of lipid-rich larval feeds, live imaging of dietary fluorescent lipid analogs, and quantification of food intake. These techniques can be applied to a variety of screening, imaging, and hypothesis driven inquiry techniques.
FAQs
The apparatus meters dry particulate material from a feed reservoir into a moving air stream. This coupling allows the powder to enter the airflow in controlled quantities rather than being introduced as an uncontrolled bulk release. The resulting dispersion supports more consistent aerosol administration, which helps researchers relate the material delivered to pharmacological or toxicological responses.
The system allows researchers to regulate aerosol concentration and exposure duration. Concentration determines how much particulate material is present in the respirable dust cloud, while duration determines how long the laboratory model encounters it. Controlling both variables helps distinguish effects associated with administered powder dose from those associated with the length of exposure.
Consistent dispersion improves the reliability of inhalation experiments because each exposure can be related more clearly to an administered powder dose. A respirable dust cloud provides the delivery format needed for respiratory studies, while controlled generation reduces variation in aerosol administration. This strengthens interpretation of observed drug effects, respiratory responses, or particulate toxicity.
A typical workflow begins with placing the dry particulate material in the feed reservoir, introducing it into a moving air stream, and producing the dust cloud for the planned exposure. Researchers then regulate concentration and duration while administering the aerosol to a laboratory model. The resulting exposure can be compared with measured pharmacological or toxicological responses.
Experiments can help relate a controlled powder exposure to respiratory responses, pharmacological effects, or toxicological outcomes. Because concentration and exposure duration are regulated, researchers can examine how changes in administered aerosol conditions correspond to observed effects. The apparatus therefore supports interpretation of dose-related findings in studies involving inhaled drugs or particulate material.
The apparatus is especially relevant when a study evaluates substances delivered through inhalation, including inhaled drugs and dry particulate materials. It provides a controlled way to administer the exposure while researchers examine respiratory responses and other pharmacological outcomes in laboratory models. Its value lies in connecting aerosol delivery conditions with the effects observed during the experiment.
