Summary: This article introduces a method for synthesizing polyethylene thermoplastic elastomers from ethylene, which is highly attractive due to its diverse applications and low cost. By synthesizing alpha-diimine nickel catalysts, polyethylene with high activity and high molecular weight was successfully obtained. These catalysts also exhibited high thermal stability and good solubility, enabling the production of polyethylene thermoplastic elastomers at high temperatures with excellent mechanical properties and strain recovery values.

Summary: A facile catalytic approach utilizing POSS-modified MgCl2-based Ziegler-Natta catalyst was reported for preparing fine UHMWPE particles, resulting in the synthesis of nascent UHMWPE with less entangled state and fine particle size. This combination of structural advantages significantly improved the toughness/stiffness/strength balance of nascent UHMWPE, especially achieving an impact strength of 113.6 kJ/m(2) with a relatively low molecular weight.

Summary: Ultra-high-molecular-weight polyethylene (UHMWPE) wear and particle-induced osteolysis contribute to the failure of total hip arthroplasty (THA) and total knee arthroplasty (TKA). Highly crosslinked polyethylene (HXLPE) has been developed to reduce wear, but its benefits are more prominent in THA than in TKA.

Summary: The tribological characteristics of ultra-high molecular weight polyethylene (UHMWPE) under unsaturated lubrication of water and brine were studied. The effect of load and speed on the friction properties of UHMWPE were analyzed. The results showed that the lubrication form of UHMWPE gradually transited from saturated lubrication to unsaturated lubrication with the increase in load or speed. Under brine-unsaturated lubrication, the anti-friction property of UHMWPE was better than that in water-unsaturated lubrication at high speed. The wear resistance of UHMWPE also varied under different lubrication conditions.

Summary: This study investigated the effects of incorporating bio-friendly nano-zeolite (NZ) on the tensile and impact properties of ultra-high molecular weight polyethylene (UHMWPE)/NZ nanocomposites through experimental and morphological assessments. The results showed significant improvements in tensile modulus, strength, and impact toughness upon the inclusion of NZ. The bonding characteristics between NZ and UHMWPE were analyzed using Fourier transform infrared spectroscopy (FTIR), and the alterations in crystalline structure were examined using differential scanning calorimetry (DSC). Super-magnified images from impact-fractured SEM micrographs were used to investigate the micro-mechanisms responsible for toughening induced by nanoparticles.

Summary: This study investigated the blending performance of ultra-high molecular weight polypropylene (UHMWPP) with high-density polyethylene (PE) and maleic anhydride grafted-polyethylene (mPE). It was found that the optimal comprehensive mechanical properties were achieved when the UHMWPP content reached approximately 50 wt%, although the elongation properties did not match those of pure PE or mPE. In addition, the tensile strength of PE/UHMWPP blends significantly decreased with decreasing UHMWPP content, while the mPE/UHMWPP blends showed minimal changes in tensile strength. Furthermore, the melt index of the blend system was substantially reduced when the UHMWPP content exceeded 10% by weight.

Summary: The high melt viscosity of ultra-high molecular weight polyethylene (UHMWPE) poses a challenge in melt-processing of nanocomposites. Blending UHMWPE with cellulose nanofiber (CNF) through melt blending led to improved mechanical properties compared to non-melt blending. The mechanical properties of UHMWPE/CNF bionanocomposites were enhanced with the addition of CNF, demonstrating the effectiveness of melt-blending processing.

Summary: This study investigates the tensile properties of uUltra-high molecular weight polyethylene (UHMWPE) fibers by using mixed solvents with improved solubility. By introducing olive oil (OO) as a poor solvent for pre-swelling UHMWPE in decalin, UHMWPE fibers with high molecular weight and low entanglement are prepared using paraffin oil as spinning solvent. The addition of 20 wt% OO results in significant molecular chain disentanglement, higher molecular weight retention, and improved tensile strength and modulus of the obtained UHMWPE fibers.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: This study investigates the effects of high energy/fluence proton radiation on the performance of HfZrOx-based FeFETs memory with different Zr content. The results show that the characteristics of FeFETs are influenced by proton radiation, and the extent of the influence depends on the Zr content. FeFETs with 50% Zr content exhibit minimal changes in memory window and demonstrate good endurance and retention performance.

Different levels of nanoporosity were prepared and tested to investigate the sensing properties, and it was found that nanoporous black gold is suitable for hydrogen sensing. The sensitivity of the film depends on its nanoporosity.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
