The Evolution of Cellulose Crystallinity During the Entire Wheat Straw Organosolv Biorefinery Process and Its Relationship with Enzymatic Hydrolysis

Sustainable Chemistry
Cellulose crystallinity is frequently associated with lignocellulosic biomass digestibility, yet its development during multistep biorefinery processing and its relationship with enzymatic hydrolysis remain difficult to isolate.

Fault Detection of Gearbox from Inverter Signals Using Advanced Signal Processing Techniques [PDF]

, 2012
The gear faults are time-localized transient events so time-frequency analysis techniques (such as the Short-Time Fourier Transform, Wavelet Transform, motor current signature analysis) are widely used to deal with non-stationary and nonlinear signals ...

Water-Based Pretreatment Combined with Severity-Optimized Organosolv Enables Near-Complete Enzymatic Hydrolysis of Wheat Straw at Reduced Energy Demand

Sustainable Chemistry
Wheat straw is an abundant agricultural residue with high potential for carbohydrate-based bioconversion, yet its efficient utilization is limited by lignocellulosic recalcitrance.

Sensors and chemometrics in downstream processing

Biotechnology and Bioengineering, 2023
AbstractThe biopharmaceutical industry is still running in batch mode, mostly because it is highly regulated. In the past, sensors were not readily available and in‐process control was mainly executed offline. The most important product parameters are quantity, purity, and potency, in addition to adventitious agents and bioburden.

Integrated downstream processing with membranes

, 2022
S.184-191 : Abb.,Tab.,Lit.Bioprocesses have several disadvantages over chemical processes: for example, they take place under normal conditions and in highly dilute aqueous solutions; in addition, most products inhibit the productivity of biocatalysts ...
