Polyether ether ketone (PEEK) composites face concurrent ultraviolet (UV) and thermo-oxidative aging in real-world service environments, yet the synergistic effects remain poorly understood.
Researchers characterized four commercial blue pigments with three conservation binders using thermal analysis, ATR-FTIR, SEM-EDS, and microscopy, revealing marked differences in thermal behavior and predominantly non-homogeneous pigment-binder mixtures. Most notably, a commercial manganese blue contained no detectable manganese, while 11 of 12 pigment-binder combinations showed non-uniform behavior, highlighting the value of verifying material composition and compatibility before conservation use.
Korea Institute of Materials Science (KIMS), led by President Chul-jin Choi, announced that a research team led by Principal Researcher Sung Mook Choi of the Energy & Environment Materials Research Division, in collaboration with research teams led by Professor Min Ho Seo of Pukyong National University and Professor Won Bae Kim of Pohang University of Science and Technology (POSTECH), has developed a highly durable platinum-nickel (PtNi) hydrogen evolution catalyst that suppresses nickel (Ni) leaching through atomic ordering.
Some of nature’s most important chemical reactions rely on the coupled movement of negatively and positively charged particles. These processes play central roles in photosynthesis, catalysis and biological energy conversion yet remain difficult to observe.
It's challenging for scientists to monitor chemical processes at nuclear facilities in real time. In this study, scientists developed new techniques to analyze chemical solutions in complex environments.
Thermo Fisher Scientific Inc., the world leader in serving science, today introduced the Thermo Scientific™ EMPAD™ G2 detector, a new detector designed to help researchers see and understand materials in unprecedented detail.
Researchers developed isosorbide-based plasticizers that made brittle poly(isosorbide carbonate) more flexible while preserving its ability to undergo ammonolysis after use. The resulting degradation products supported plant growth, including in an edible vegetable, highlighting a new way to design plastics with a useful end-of-life function.
Researchers showed that alkaline cyanide aerosols interacting with six mineral substrates can spontaneously form mineral-organic hybrid materials, with mineral identity and reaction time shaping the resulting nitrogen-rich organic structures. The findings reveal that minerals can actively influence prebiotic molecular complexity while organic coatings can also stabilize or transform the underlying mineral phases.
Bruker Corporation today announced an expanded strategic collaboration with Atinary Technologies Inc., the pioneer of Self-Driving Labs® technologies and AI-driven R&D with applications in pharmaceuticals, chemicals, energy, and materials.
Virginia Tech chemist and chemical engineer Guoliang “Greg” Liu and his lab have developed a process that converts the plastic polyvinyl chloride (PVC) into polyalphaolefin, a key component in lubricants such as engine oil.
