Compared with pure PLA, with the rise of PCL content, the 4D-printed PLA/PCL composites show decreased glass transition temperature (Tg) from 67.2 to 55.2 掳C. Through the precise control of the deformation condition, controllable sequential deformation with an outstanding shape memory effect can ...
To interpret the non-linear shape of H₂S and the non-planar shape of PCl₃ based on VSEPR theory, we will analyze the molecular geometry of both compounds step by step.Step 1: Determine the Valence Electrons - H

Human emotions fluctuate over time. However, it is unclear how these shifting emotional states influence the organization of episodic memory. Here, we examine how emotion dynamics transform experiences into memorable events. Using custom musical pieces a
In the context of 4D printing, the term “fourth dimension” pertains to the capacity of materials to change their shape or form once they have been manufactured. This characteristic enables them to possess enhanced functional capabilities and enables the creation of applications that prioritize perfor...
Fig. 2. Classification of poly(lactic acid) (PLA) relative to other biodegradable polymers. Biodegradable polymers are classified into two types according to their origins: petrochemical or renewable. Some biodegradable from petrochemical resources are polycaprolactone (PCL), poly(glycolic acid) (PGA),...
The mass loss was substantially accelerated, in enzymatic degradation when Pseudomonas cepacia lipase was added, which was reported to accelerate the degradation of PCL. During hydrolytic degradation a continuous decrease in elongation at break (?B) from ?B = 800% to 15% was observed in a time...
