A novel top‐to‐bottom film restructuring strategy is applied to perovskite films, taking advantage of high penetration of vapor‐phase ligand. A gradient‐distributed 2D perovskite structure is built up from top surface to film bulk, meanwhile, inhomogeneity at the buried interface is mitigated, which leads to high quality perovskite films with improved ...

Model predictive control with inline parameter adaptation for direct crystal growth rate regulation
Abstract In batch cooling crystallization, many interactive factors, including supersaturation, reactor dimensions, and operating conditions, govern crystal growth and significantly influence product properties. Variables such as temperature or refractive index are used as surrogate control variables but have limitations in capturing growth rate ...

Second Molar Uprighting with Temporary Anchorage Devices: A Finite Element Study
BACKGROUND AND OBJECTIVE: Premature loss of mandibular first molar is a common problem in adults. Mesial tipping of second molar may occur in this situation. Various orthodontic mechanics have been proposed for molar uprighting. The aim of this study was

Small‐Scale Magnetic Peristaltic Soft Robot With Mobility and Transport Capabilities
This study introduces a miniature, untethered soft magnetic microrobot with peristaltic capabilities for both locomotion and cargo transport. Eight helically magnetized elastomeric strips deform under rotating fields (10–80 mT, 1–5 Hz), enabling movement across rods and lumina at up to 4.1 body lengths min‐¹.

Inspired by the Mexican jumping bean, this study presents a centimeter‐scale, electronics‐free robot that merges principles from both the animal and plant kingdoms. A thermo‐responsive actuator mimicking larval motion, enclosed within a uniquely shaped plant‐seed‐inspired shell, generates jumping, rolling, flipping, sliding, and climbing through ...

Success Rates Of Temporary Anchorage Devices Placed In An Orthodontic Clinic [PDF]
In recent years, the use of a variety of temporary placed implants to attain absolute anchorage has been described in the orthodontic literature. The use of temporary implants, fixed to bone, overcomes some of the limitations of traditional anchorage and

Thermally Drawn Bioelectric Catheters: Enabling Proprioceptive Endovascular Navigation
This work introduces a novel bioelectric navigation system eliminates the need for harmful fluoroscopy during endovascular surgeries. A bespoke 16‐electrode catheter is fabricated using rapid thermal drawing and laser micro‐machining. Paired with a real‐time tracking algorithm fusing vascular geometry detection and distance estimation, this technology ...
