Advanced Healthcare Materials, EarlyView.Negative‐ and positive‐staining TEM is essential for rapid nanometer‐resolution characterization of organic specimens ranging from nanoparticles to cells. Uranyl salts are widely used negative‐/positive‐stains but are radioactive and highly toxic to users and the environment.

Advanced Healthcare Materials, EarlyView.Highly sprouting organoid‐like neurovascular spheroids (NVUs) are developed, featuring cell‐loaded poly‐3‐hydroxybutyrate 4‐hydroxybutyrate(P34HB) porous microsphere cores embedded within Gelatin Methacryloyl. NVUs formed complex vascular plexuses and secreted extracellular matrix in vitro, simulating autologous nerves and blood interaction.

Advanced Healthcare Materials, EarlyView.This study develops itaconate‐based polymer microparticles (IA‐MPs) for macrophage‐targeted intracellular delivery, overcoming the limitations of traditional itaconate administration. IA‐MPs achieve controlled release through phagocytosis, reducing pro‐inflammatory cytokine expression and reprogramming macrophage metabolism toward glycolysis.

Infrared analysis of carbon blacks
Carbon, 1987Results of computer-assisted analyses of the ir spectra of carbon blacks are presented. Absorption bands corresponding to specific surface functional groups have been identified and analysed by dispersing the blacks in KBr at different concentrations (0.03%-0.15% wt/wt). With few exceptions, Beer's law is obeyed.

Carbon Black Reinforced Elastomers [PDF]
, 2015 Carbon black is commonly added in large quantities to elastomers/rubbers as so-called reinforcing agents: less so to raise the modulus, but more so to increase the tensile strength at break, the abrasion resistance and fatigue properties. The dynamic properties are commonly somewhat negatively influenced.

Endor studies of carbon black and carbon black-polymer composites
Carbon, 1987Abstract Electron-nuclear double resonance (ENDOR) spectra have been obtained at the free proton frequency for a carbon black and a carbon black-polymer composite, at temperatures ranging from 130 K to 350 K. The ENDOR spectra show an unusual dependence on the saturation of the associated homogeneously broadened ESR resonance, as “non-saturating ...

Black Carbon and the Carbon Cycle
Science, 1998When vegetation and fossil fuels burn, the combustion creates "black carbon" that becomes distributed throughout the environment. Determining how it is created and where it goes is important for studying the past history of fire and for understanding global carbon and oxygen budgets.
