Synergistic role of graphene oxide-magnetite nanofillers contribution on ionic conductivity and permeability for polybenzimidazole membrane electrolytes

Efficient nanofillers within polymeric electrolytes are an interesting design for constructing high-performance membranes for direct methanol alkaline fuel cells. In this work magnetite (Fe3O4) particles are synthesized onto graphene oxide (GO) nanofillers and incorporating into a polybenzimidazole (PBI) matrix for membrane formation. The Fe3O4 nanoparticles are simultaneously anchored onto GO carbon basal planes to form GO-Fe3O4 via the solvothermal process. The pristine PBI, PBI/GO, PBI/Fe3O4, and PBI/GO-Fe3O4 composites are formulated and doped with potassium hydroxide solution to form ionic conductors. GO nanofillers suppress the methanol permeation rate in PBI/GO-Fe3O4 composite membranes while the anchored Fe3O4 nanoparticles result in a bumpy surface, reducing chain packing and promoting anionic conductivity via the loose polymeric free volume. Therefore, the conductivity-to-permeability selectivity of PBI/GO-Fe3O4 composite membrane is improved three times than other samples. The maximum peak power density (Pmax) of a fuel cell employing the PBI/GO-Fe3O4 composite membrane achieves 233 mW cm?2 at 80 C. The superior power output is attributed to the combined effect of the enhanced anionic conduction resulting from anchored GO-Fe3O4 particles’ steric hindrance on polymer chains to enlarged ion diffusion pathways, and the reduced methanol cross-over from the GO’s high aspect ratio to retard molecular permeation in the composite membrane.

Synthesis of 1,8,11,12-tetrachlorotricyclo[6.2.2.02,7]dodec-2- ene-4,5:9,10-bis(dicarboximides)

1,8,11,12-Tetrachlorotricyclo[6.2.2.02,7]dodec-11-ene-4,5:9,10- bis(dicarboximides) containing similar and different substituents on the nitrogen atoms were selectively synthesized by reactions of the corresponding dianhydride and imide anhydrides with aliphatic and aromatic amines in dimethylformamide. The structure of the resulting diimides was confirmed by independent synthesis via Diels-Alder reaction of N-substituted 1,2,3,4-tetrachlorobicyclo[4.4.0]deca-2,4-diene-8,9-carboximide with substituted maleimides.

A facile and economical procedure for the synthesis of maleimide derivatives using an acidic ionic liquid as a catalyst

Seven maleimide derivatives were synthesized in good yields and high purity from the corresponding maleamic acids using a Bronsted acidic room temperature ionic liquid (RTIL) as a catalyst. The products were obtained through merely a decanting and removal of the solvent, suggesting that this procedure is superior to the conventional routes, in which the strong organic/inorganic acids were used as the catalysts, as well as a complicated post-processing procedure for the separation and purification of the products was employed.

Recent developments in cholinesterases inhibitors for Alzheimer’s disease treatment

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder of the central nervous system (CNS) which is the most common cause of dementia in the elderly. It is characterized by the deficits in the cholinergic system and presence of characteristic hallmarks: neurofibrillary tangles and amyloid plaques. Since the cholinergic system plats an important role in the regulation of learning and memory processes it became a target for the design of antialzheimer drugs. Cholinesterase inhibitors enhance cholinergic transmission indirectly, by inhibiting the enzyme which hydrolyses acetylcholine. It has been also demonstrated that acetylcholinesterase (AChE) is involved in the development of amyloid plaques. Therefore, substances which are AChE inhibitors (AChEI) are the only drugs approved for the symptomatic treatment of AD. This review presents the main classes of cholinesterase inhibitors developed recently for the treatment of AD. We hace started with the analogues of the existing drugs: tacrine, donepezil, rivastigmine and galantamine which are still of interest for many research groups. Among them there is a very interesting group – dual binding site inhibitors characterized by increased inhibitory potency against AChE and amyloid plaques formation. There is also a group of compounds with additional properties such as: antioxidant activity, affinity to 5-IIT3 receptors, inhibition of N-methyltransferase that metabolize histamine, which can be beneficial for the treatment of AD. Furthermore there are some interesting compounds which belong to different chemical groups also of natural origin. In this review we sum up current research concerned with development of AChEIs which can be more effective in the future treatment of AD.

Thermally cleavable surfactants

Two new surfactant molecules are reported which contain thermally labile Diels-Alder adducts connecting the polar and non-polar sections of each molecule. The two surfactants possess identical non-polar dodecyl tail segments but exhibit different polar headgroups. The surfactants become soluble in water when anionic salts are formed through the deprotonation of the surfactant headgroups by the addition of potassium hydroxide. When either surfactant is exposed to temperature above about 60 C., the retro Diels-Alder reaction occurs, yielding hydrophilic and hydrophobic fragments and the aqueous solutions of the surfactants subsequently exhibit loss of all surface-active behavior.

Polybenzimidazole (PBI)-functionalized silica nanoparticles modified PBI nanocomposite membranes for proton exchange membranes fuel cells

Polybenzimidazole (PBI) has been chemically bonded to silica nanoparticles (SNPs) through an ozone-mediated process using N-(p-carboxyphenyl)maleimide (pCPM) functionalized SNPs (SNP-pCPM) as precursors, to enhance the interfacial compatibility between SNPs and PBI in PBI/SNP nanocomposites. The PBI-functionalized SNPs (SNP-PBI) have been well characterized and used as inorganic nanofillers for preparation of PBI/SNP-PBI membranes for fuel cells. Addition of PBI-SNP to PBI membranes enhances their thermal and mechanical properties as well as decreases their phosphoric acid uptakes. For the PBI/SNP-PBI membrane with 10wt% of SNP-PBI, it shows a proton conductivity of about 50mScm-1 at 160C, which is 25% higher compared to the pristine PBI membrane. Consequently, the PBI/SNP-PBI membrane demonstrates a maximum power density of 650mWcm-2 in a single cell test, compared to the value of 530mWcm-2 read from the test for pristine PBI membrane.

Preparation of polybenzoxazine-functionalized Fe3O4 nanoparticles through in situ Diels-Alder polymerization for high performance magnetic polybenzoxazine/Fe3O4 nanocomposites

Hybrids and nanocomposites of polymer and magnetic Fe3O4 nanoparticles have been utilized as magnetically-responsive materials and magnetically-directed nanoparticles. In this work, we prepare polymer-functionalized Fe3O4 nanoparticles through in situ Diels-Alder polymerization using maleimide-functionalized Fe3O4 nanoparticle as a precursor. Polybenzoxazine-functionalized Fe3O4 nanoparticles (MNP-PBz) have been obtained and characterized with Fourier Transform Infrared, X ray photoelectron, and Raman spectroscopies. The high saturation magnetization value of 51.9emu g-1 of the MNP-PBz nanoparticles demonstrates its superparamagnetism. Moreover, MNP-FBz has been utilized as a nanofiller for preparation of cured PBz/MNP-PBz nanocomposites, which contain various MNP-PBz contents of 67, 50, 33, and 17wt.%. The sample of PBz/MNP-PBz-67 shows a storage modulus of 8.0GPa, a saturation magnetization value of 37.6emu g-1, and a glass transition temperature above 380C. As a result, the PBz/MNP-PBz nanocomposites could be classified as magnetically-responsive high performance materials.

Isobutylene-rich macromonomers: Dynamics and yields of peroxide-initiated crosslinking

New isobutylene-rich elastomers bearing multiple pendant styrenic, acrylic, maleimidic, vinylic, and allylic functional groups have been prepared and examined in the context of peroxide-initiated crosslinking. Halide displacement from brominated poly(isobutylene-co-isoprene) (BIIR) by the requisite carboxylate nucleophiles in homogeneous toluene solutions provide the desired esters in quantitative yield without complications from dehydrohalogenation or premature crosslinking. Heating the resulting macromonomers with dicumyl peroxide to 160 C under solvent-free conditions gives thermoset derivatives, with reaction rates and yields depending markedly on functional group structure. In general, high cure extents can only be achieved using highly reactive pendant functional groups, owing to the competitive balance between crosslinking through C=C oligomerization, and degradation through beta-scission of backbone macroradical intermediates. Independent control of crosslinking rates and cure extents is gained through the use of nitroxyl radical traps bearing acrylate functionality.
