Shear and Elongational Flow Properties of Long-Chain Branched Poly(ethylene terephthalates) and Correlations to Their Molecular Structure

, 2016
Reactive processing with low-molar-mass modifiers is a well-known method to create long-chain branched (LCB) structures in a poly­(ethylene terephthalate) (PET) melt. However, less is known about the elongational flow properties of LCB-PET.

The plastisphere in marine ecosystem hosts potential specific microbial degraders including Alcanivorax borkumensis as a key player for the low-density polyethylene degradation.

Journal of Hazardous Materials, 2019
Most plastics are released to the environment in landfills and around 32% end up in the sea, inducing large ecological and health impacts. The plastics constitute a physical substrate and potential carbon source for microorganisms.

Soft Robotic Excretory Care Simulator for Nursing Education: Functional and Perceptual Biomimetics Approach

Advanced Robotics Research, EarlyView.
A soft robotic simulator is developed to replicate the digital removal of feces (DRF), a sensitive yet essential nursing procedure. Integrating soft actuators, sensors, and a realistic rectal model, the simulator balances functional fidelity with perceptual realism. Engineering evaluations and nurse feedback confirm its potential to enhance training in

Studies on Polyethylene Terephthalate. (Part 2). Analysis of Ethyleneglycol and Diethyleneglycol in Polyethylene Terephthalate

The Journal of the Society of Chemical Industry, Japan, 1962
ポリエチレンテレフタレート(PET)中に存在するジエチレングリコール(DEG)が,重合体の性質に大きい影響を及ぼすと考えられるので,重合体中のエチレングリコール(EG)およびDEGの化学的分析法を検討し,EGの分析法として四酢酸鉛法をDEGの分析法として過ヨウ素酸・重クロム酸カリウム法を見出し,これによってEG-DEG混合物ではDEG含有量を相対誤差1%以下で求められるようになり,重合体中のDEGも実用に差支えない程度に定量できるようになった。これによって求めたTs=258.1℃の重合体のDEG含量は約2mol%である。

Infrared properties of polyethylene terephthalate films [PDF]

Solar Energy Materials, 1982
Abstract The infrared radiation properties of polyethylene terephthalate films are calculated from the optical constants. Hemispherical total transmittance and emittance are given as functions of thickness. The difference between these properties and those of glass will significantly affect the thermal conductance of windows or solar collector covers.

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots

Advanced Robotics Research, EarlyView.
This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.

Bioinspired Soft‐Skeleton Robotics With Cooperative Shape Transformation and Stiffness Adaptation

Advanced Robotics Research, EarlyView.
A bioinspired soft‐skeleton robot that integrates variable‐stiffness chain skeletons into a soft textile skin is developed. The chain skeletons are highly flexible initially but can stiffen upon pneumatic actuation, enabling large deformation and enhanced load‐bearing capacity.
