Abstract Bio‐based and bio‐degradable plastics such as polybutylene succinate (PBS) have the potential to become sustainable alternatives petrochemical‐based plastics. Polybutylene can be produced from bio‐based succinic acid 1,4‐butanediol using first‐generation (1G) or second‐generation (2G) sugars. A cradle‐to‐grave environmental assessment was performed for PBS products in Europe investigate non‐renewable energy use (NREU) greenhouse gas (GHG) impacts. The investigated are single‐use...
Cadmium-containing quantum dot (QD) nanoparticles are integrated into electronic displays because of their ability to efficiently convert colors. There conflicting accounts as whether these particles present a hazard the environment, they have been studied either (1) embedded QDs in display screen films or (2) model with small, hydrophilic ligands. Both approaches limitations that we addressed by synthesizing featuring core–shell structure and thick polymer coating commercial devices probe...
Abstract Thanks to an accelerating voltage in the range of 30 300 kV, electron beam can pass through a thin specimen and form image with sub‐Ångström spatial resolution. When impinging on crystalline specimen, fast electrons scatter diffract. The transmitted pattern depends local thickness, density, crystal structure, chemical nature sample. transmission microscope (TEM) shapes incoming using magnetic lenses onto and, different set lenses, focuses projected camera. final magnification...
Nanomaterials (NMs) entering the human body via oral route are subjected to successive digestive chambers in gastrointestinal (GI) tract, which altered their physicochemical properties and toxicity profile.
Light emissive organics and inorganic nanoparticles are substance classes competing for applications in displays the form of organic light emitting diodes (OLEDs) quantum LEDs (QLEDs), respectively. Upcoming classes, perovskites Q-OLED displays, also contain novel nanomaterials these applications. However, safety viability substances is difficult to assess quickly broadly because their complexity, inherently different structures, rapid evolution literature. We propose use an alternatives...
Commercially used quantum dots (QDs) exemplify complex nanomaterials with multiple components, though little is known about the type of interactions between these components in determining overall toxicity this material. We synthesized and characterized a functional QD (CdSe/ZnS_P&E) that was identical structure composition to patented commercially applied combinations its (CdSe, CdSe/ZnS, ZnS, CdSe_P&E, ZnS_P&E, P&E). Cells exposed incremental concentrations materials were investigated for...

Chemicals and materials with essential functional uses are central to economic social well-being. However, the development application of such items may be challenged when sustainability factors considered. These further by disciplinary gaps concerns over reproducible responsible research. Here, we detail a checklist for early career researchers on how "to do" research chemicals, materials, processes, products in manner that is safe sustainable design. The contains 20 organized into five...
