Recovery of spores and crystals from the fermentation broth of Bacillus thuringiensis (Bt) was studied using the membrane separation technology. Four types of polymeric membranes, with different characteristics, in the range of microfiltration (MF) and ultrafiltration (UF) were used for evaluating their permeate flux and spore–crystal recovery capacity. Results indicated that both MF and UF mem...

Deep eutectic solvents (DES) have recently emerged as a new class of inexpensive biodegradable and additives with diverse applications. In this study, family non-ionic deep (NIDES) is proposed for the first time membrane preparation. Three types NIDES, N-methylacetamide-acetamide (DES-1), N-methyl acetamide-N-methyl urea (DES-2), acetamide-N,N′-dimethyl (DES-3) were synthesized used to dissolve...

Solid-state Li metal batteries with solid electrolytes have built a potential way to solve the safety and low energy density problems of current commercial Li-ion liquid electrolyte. As key component solid-state batteries, require high ionic conductivities good mechanical properties. We designed composite electrolyte (CSE) consisting poly(vinylidene fluoride-hexafluoropropylene) (PVDF-HFP)-Li6....

Early works have shown that highly reproducible piezoelectric film PVDF (Poly(vinylidene fluoride)) can be reliably used in a wide range of precise stress and stress-rate measurements. The direct stress-derivative or stress-rate PVDF signals have nanosecond resolution and higher operating stress limits than any other technique. Uses of PVDF stress gauges have been conducted in many fields of sh...

• PANI-TNT nanocomposite was used for modification of pure PVDF membrane. Phase inversion method to develop PVDF-PANI-TNT nanofiltration membranes. Developed membranes show excellent self-cleaning properties in filtration processes. Water flux, hydrophilicity and antifouling improved by adding PANI-TNTs. In this research article, the (polyvinylidene fluoride)–PANI (polyaniline)–titanium nanotub...

Mixtures of poly(vinylidene fluoride) (PVDF) and ε−caprolactam (CPL) have been investigated as models for possible cross-interactions between vinylidene fluoride and amide structural units, that might account for the very fine phase morphology previously observed in PVDF/polyamide 6 blends. Over the entire composition range, the PVDF/CPL mixtures are monophase above the PVDF melting temperature...
