Synergistic effects of silica fume, nanomaterials and inorganic salts on the hydration and compressive strength of low-density oil well cement slurry

Cement
During offshore cementing at shallow depth, the low-temperature environment at the bottom of the sea and the low-density requirement of the cement slurry significantly hinder the strength development of oil well cement systems.

Small scale purification and biophysical characterization of haptoglobin derived from human Cohn fraction IV

Biotechnology Progress, EarlyView.
Abstract Haptoglobin (Hp) is a polymorphic acute phase α‐2 glycoprotein found in plasma that plays a critical role in binding, neutralizing, and removing cell‐free hemoglobin (Hb) from the circulation. Under clinical conditions characterized by high levels of hemolysis, such as in patients with sickle cell disease (SCD), large quantities of cell‐free ...

Unveiling the Potential of Metal and Non‐Metal Modified Porous Carbon for the Electrochemical Reduction of CO2

Carbon Energy, EarlyView.
Earth‐abundant metal‐ and non‐metal‐modified porous carbons offer a highly tunable platform for electrochemical CO2 reduction. This review shows how electronic interactions, active‐site coordination, pore architecture, and cooperative catalytic effects jointly govern intermediate stabilization, product selectivity, and device‐relevant CO2RR performance.
