Microwave‐Assisted Subcritical Water Extraction Method for the Optimized Isolation of Cellulose From Residual Soybean Hulls

open access: yesChemSusChem, Volume 19, Issue 17, 14 September 2026.
Almost pure cellulose was extracted from soybean hulls by microwave‐assisted alkaline treatment (MW‐NaOH) and characterized. The microwave‐assisted subcritical water extraction (MASWE) of waste biomass falls within the circular economy approach, promotes sustainability, and reduces both treatment times and the use of harsh chemicals.

Effect of thermal ageing on impact ductility of the nuclear reactor pressure vessel steel SA533B and its weld metal

open access: yes, 1987
The effects of long term thermal ageing on the impact toughness of a reactor pressure vessel (RPV) steel SA533B and its submerged arc weld metal have been studied. The annealings were carried out at 350–450 °C with a duration of 1–5 years. An estimate of

The development of advanced creep constitutive equations for high chromium steel P91 at low stress range [PDF]

open access: yes, 2013
Diffusion dominates the creep deformation at low stress range for high chromium steel P91. Brittle creep fracture is caused by cavity nucleation, growth and coalescence of cavities and large precipitates (Laves phase and M23C6) at grain boundary under ...
