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.

This is a method to visualise leukocyte adhesion to the endothelium in harvested pressurised vessels. The technique enables studying vascular adhesion under shear flow with differing intraluminal pressures up to 200 mmHg thus mimic-ing the pathophysiological conditions of high blood pressure.
FAQs
The key biological sequence begins when sterile talc contacts the pleural surfaces and triggers localized inflammation. This response promotes fibrin deposition, followed by development of fibrous adhesion between the parietal and visceral pleura. The resulting adhesion joins the pleural layers and helps create the lasting pleurodesis needed to reduce reaccumulation in the pleural space.
Pleural adhesion reduces the potential space between the parietal and visceral pleura. When these layers become joined, fluid or air has less room to reaccumulate, which supports control of recurrent pleural problems. This mechanism is clinically relevant because it can reduce repeated drainage procedures and help maintain the intended therapeutic result.
Thoracoscopy provides the setting for clinicians to distribute sterile talc across both the parietal and visceral pleura. Contact with these surfaces is important because the subsequent inflammatory and fibrotic response must connect the pleural layers. The approach therefore links direct visualization and application with formation of the adhesion required for pleurodesis.
During thoracoscopy, clinicians apply sterile talc to the pleural surfaces and distribute it across the parietal and visceral pleura. The treated surfaces then undergo localized inflammation, fibrin deposition, and later fibrous adhesion. This sequence is the procedural pathway by which talc application produces pleurodesis and helps limit renewed accumulation of fluid or air.
The technique is used primarily when pleural fluid or air repeatedly returns and preventing another episode is clinically important. Its main applications are recurrent malignant pleural effusion and recurrent pneumothorax. In these settings, creating adhesion between the pleural layers can support symptom control and reduce the need for repeated procedures to drain the pleural space.
By helping obliterate the pleural space, the intervention can reduce symptoms associated with recurrent accumulation of fluid or air. It may also limit repeated drainage procedures and support minimally invasive thoracic care. The intended outcome is not simply talc delivery, but a lasting pleural adhesion that helps maintain control of the underlying recurrent problem.
