This study explores the impact of blending polyethylene terephthalate (PET) with polybutylene terephthalate (PBT) on the thermal, structural, and mechanical properties of 3D-printed materials. Comprehensive analyses, including Fourier-transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), X-ray diffraction (XRD), differential scanning calorimetry (DSC), and mechanical testing, were conducted to assess the influence of blend composition. FT-IR confirmed that PET and PBT blend physically without transesterification, while TGA showed enhanced thermal stability with increasing PET content. XRD revealed that PET and PBT crystallize separately, with the crystallinity decreasing sharply for blends with more than 50% PET. The DSC results indicated that PET effectively slows down the crystallization kinetics of PBT, promoting cold crystallization. Mechanical tests demonstrated that the elastic modulus remains relatively unchanged, but the strain at break decreases with a higher PET content, indicating increased stiffness and reduced ductility. Overall, incorporating PET into PBT improves 3D-printability and dimensional stability, reducing warpage and enhancing print precision, making these blends advantageous for 3D-printing applications.

Abstract Polyethylene terephthalate (PET) is a kind of high performance engineering plastic. However, the application of pure PET is subject to limitation because of its slow crystallization rate. In order to overcome this difficulty, thermoplastic resins are often added into PET matrix by a compounding technique. Polybutylene terephthalate (PBT) possesses many advantages such as a high degree of crystallinity and rapid molding, thus, is very suitable to adjust the crystallization behaviors of PET. In this work, the crystallization behaviors of PET/PBT alloys were studied by a differential scanning calorimeter (DSC) and thermal platform polarizing microscope. The obtained results indicate that the content of PBT could tune the melting and crystallization behaviors of the alloy. The parameters of non-isothermal crystallization of the alloys for blends were analyzed by the Jeziorny and Kissinger methods. The non-isothermal crystallization process for PET, PBT and PET/PBT alloys fit the Jeziorny model well at the early stage, but there is a certain small deviation at the later stage, indicating that the nucleation mechanism of PET/PBT alloy is complicated. In addition, the crystallization rate accelerates with an increase in cooling rate. The alloys show the best crystallization performance when the content of PBT is 10 wt%, and their crystallization activation energy reaches up to -201.78 kJ/mol.

271 Background: Evaluation of tumor response to radiation therapy in pancreatic ductal adenocarcinoma (PDA) using conventional radiological tests is difficult due to generally small size and inflammatory or fibrotic changes of radiated tissue. Although increasing evidence has shown that 18-F-fluorodeoxyglucose-positoron emission tomography (FDG-PET) can assess functional changes in various tumors, available data in PDA with radiation therapy is scarce. In this study, we investigated the role of FDG-PET in long-term monitoring tumor response to proton beam therapy (PBT) for PDA. Methods: Thirty-four locally advanced PDA patients with pre- and post-PBT FDG-PET data were included in this study. Local tumor responses by computed tomography (CT) and FDG-PET were defined as below: response group in CT (complete response: CR, partial response: PR, stable disease: SD, progressive disease: PD) was defined according to Response Evaluation Criteria in Solid Tumors, but only evaluation of primary tumor; and in FDG-PET, CR was defined as disappearance of FDG uptake, PR as decrease, SD as unchange, and PD as increase, compared to pre-PBT data. We evaluated tumor response at three different time points: 0-3, 3-6, and 6-12 months after PBT. Also serum CA19-9 values were evaluated. Results: Radiation doses were 50.4-70.2 GyE and 28 (82%) patients received concomitant chemotherapy. During the follow-up period (median 19 months), a total of 90 FDG-PET tests were performed. At the first time point, SD was noted in 90% (9/10) of patients by CT, whereas CR or PR in all by FDG-PET. At the second point, 39% (7/18) of patients demonstrated PR by CT, whereas 91% CR or PR by FDG-PET. Two patients with PD by FDG-PET were diagnosed as SD by CT, while one patient with PD by CT was diagnosed as PR by FDG-PET. At the third point, four patients with PD by FDG-PET were diagnosed as PR or SD by CT. Serum CA19-9 values supported FDG-PET findings. In four of 14 patients with serial FDG-PET, the maximum effects were noted at the second point. Conclusions: Serial FDG-PET can detect changes in local tumor response to PBT for PDA earlier and more sensitively than CT. Of note, there is the risk for false positive in early post-PBT FDG-PET.

Conductive plastics are made by placing conductive fillers in polymer matrices. It is known that a conductive filler in a binary polymer blend with a co-continuous morphology is more effective than in a single polymer, because it aids the formation of a ‘segregated conductive network’. We embedded a relatively low-cost conductive filler, aluminium nano platelets, in a 60/40 PBT/PET polymer blend. While 25 vol.% of the Al nanoplatelets when placed in a single polymer (PET) gave a material with the resistivity of an insulator (1014 Ωcm), the same Al nano platelets in the 60/40 PBT/PET blend reduced the resistivity to 7.2 × 107 Ωcm, which is in the category of an electrostatic charge dissipation material. While PET tends to give amorphous articles, the 60/40 PBT/PET blends crystallised in the time scale of the injection moulding and hence the conductive articles had dimensional stability above the Tg of PET.

The pyrolysis of plastic waste is a promising method to reduce waste accumulation while it could provide value-added transportation fuels. The main goal of this study is to investigate the influence of PET and PBT contamination during plastic pyrolysis oil production utilizing HDPE, LDPE, PP, and PS mixtures as these plastics are good candidates for transportation fuel production via pyrolysis and distillation. Seven different waste blends were prepared and pyrolyzed in a laboratory-scale batch reactor equipped with reflux. Mass balance, gas analysis, thermogravimetric analysis, and deposit formation were evaluated. It was concluded that by increasing the PET or PBT concentration in the initial solid waste mixtures, the oil production decreases while the amount of gases increases. Additionally, either PET or PBT generates operational difficulties due to they form deposits in piping system in form of benzoic acid. The maximum concentration of these plastic waste materials was 20% (PET) and 25% (PBT) in this study as further increase blocked the cross-section of piping, causing operational difficulties. Based on the obtained results the concentration of PET and PBT should be limited in waste mixtures when transportation fuel production is desired.

The need for solid-waste management has pushed the development of alternative systems for recycling and revalue used plastic containers. Poly(ethylene terephthalate) (PET) is being widely used as raw material for beverage bottles. However, as has been widely reported, PET undergoes degradation and hydrolysis when reprocessed. On the other hand, poly(butylene terephthalate) (PBT) is another thermoplastic polyester with easy processability but high brittleness and cost. Hence, it has been blended with other polymers such as polypropylene to overcome its disadvantages. In this work, bentonite was incorporated into recycled PET and PBT/polypropylene blends by extrusion. Rheological and tensile properties and processability of the composites thus prepared were studied. Results showed a strong newtonean character of extrudates of recycled PET and higher viscosities and a more pseudoplastic behavior and improved reprocessability when bentonite was added to PET. Furthermore, inclusion of the filler increased its initial degradation temperature, as observed during rheological testing. All composites displayed a brittle behavior. However, the tensile properties of PET composites were not strongly deteriorated. There was a slight increase in the Young’s modulus values and in the tensile strength, with unnoticeable effects on the elongation at break. The Young’s modulus values of PBT/PP composites were not significantly affected.

Exclusive chemical conversions of polyesters [poly(ethylene adipate) (PEA), poly(butylene adipate) (PBA), poly(ethylene terephthalate) (PET), poly(butylene terephthalate) (PBT)] to the corresponding monomers (diethyl adipate, diethyl terephthalate, ethylene glycol, 1,4-butane diol) by transesterification with ethanol using Cp’TiCl3 (Cp’ = Cp, Cp*) catalyst have been demonstrated. The present acid-base-free depolymerizations by Cp’TiCl3 exhibited completed conversions (>99%) of PET, PBT to afford diethyl terephthalate and ethylene glycol or 1,4-butane diol exclusively (selectivity >99%) without formation of any other by-products in the NMR spectra (150–170 °C, Ti 1.0, or 2.0 mol%). The resultant reaction mixture after the depolymerization of PBA with ethanol via the CpTiCl3 catalyst (1.0 mol%, 150 °C, 3 h), consisting of diethyl adipate and 1,4-butane diol, was heated at 150 °C in vacuo for 24 h to afford high molecular weight recycled PBA with unimodal molecular weight distribution (Mn = 11,800, Mw/Mn = 1.6), strongly demonstrating a possibility of one-pot (acid-base-free) closed-loop chemical recycling.

Nell'ambito della Diagnostica per Immagini, l'imaging ibrido sta assumendo un ruolo fondamentale in molte applicazioni cliniche, tra cui oncologia, neurologia e cardiologia. La possibilità di integrare informazioni complementari, funzionali e morfologiche, in un'unica immagine, permette di valutare con estrema accuratezza varie tipologie di malattie, diminuendo i tempi di acquisizione e i disagi per i pazienti. La risonanza magnetica, in sostituzione alla TAC nel sistema integrato PET/TC, introduce notevoli vantaggi quali l'acquisizione simultanea dei dati, l'ottimo contrasto dei tessuti molli, l'assenza di radiazioni ionizzanti e la correzione degli artefatti da movimento; ciò migliora l'accuratezza delle immagini e, di conseguenza, il processo diagnostico. Nonostante sia un interessante strumento di diagnostica e l'apice dello sviluppo tecnologico in imaging nucleare, vi sono alcune problematiche che ne impediscono la diffusa adozione, tra cui le interferenze reciproche tra le due modalità, i costi elevati e ancora una ridotta pubblicazione di articoli al riguardo.

Resumo:

Recently, systems that integrate positron emission tomography and magnetic resonance imaging (PET/MR) have become available for clinical use. This new technology, which combines the high spatial resolution and superior soft-tissue contrast of MR with the picomolar sensitivity, quantitative capabilities, and wide array of tracers of PET, has the potential to benefit patients and provide insights that were previously unattainable in standalone systems. Simultaneous measurement of PET and MR parameters provides complementary information, allowing for a more complete assessment of disease, as well as cross validation and calibration of MR and PET measurements and techniques. To take full advantage of such a multi-modal system, accurate quantification of the PET data is necessary. Due to the low spatial resolution of PET – which can be further reduced by external factors like patient motion – and the inherent lack of anatomic detail, accurate quantification can be challenging. The simultaneously acquired MR information provides an opportunity to optimize PET quantification and analysis. In order to fully realize the benefits provided by the simultaneously acquired MR data, the MR data cannot be treated as discrete sequences, but as the continuous flow of information. This is due to differences in the time required for data collection to generate PET and MR images. This work describes the development and optimization of a pipeline for the reconstruction and analysis of PET data in a brain-dedicated prototype PET/MR system, the BrainPET (Siemens Healthcare). First, the performance of the BrainPET system was optimized for neurological imaging. MR-hardware interference and characteristics of the PET camera were quantified and a method for multimodal alignment was developed. To simplify and streamline the reconstruction and quantification process, a platform was designed which utilizes the functionality of a number of specialized brain imaging analysis software packages in an automated fashion. Second, MR-based methods addressing specific challenges to PET quantification were addressed. Simultaneously acquired structural MR data was used to correct the PET data for attenuation and partial volume effects. The use of MR data for motion correction was addressed and a unified algorithm which derives motion estimates from the PET data when MR data is unavailable was presented. Finally, the value of the optimized PET processing for neurological studies was evaluated in three instances: first an upper limit on the physiologic noise introduced by MR imaging on cerebral metabolism was estimated using PET and found to be minimal; next the benefit of MR-based motion correction and partial volume effect correction were estimated in a patient study; and lastly, a method to derive the PET radiotracer input function from the PET data using multiple MR sequences was presented.
