ジャーナル 認証ありWe identified ways to stop the dissociative swelling of graphene oxide membranes in the presence of humidity by incorporating nanodiamonds. The stabilization phenomenon is identified as an enhanced electrostatic interaction between the negatively charged graphene oxide sheets and the positively charged carbonaceous nanodiamonds. Essentially, through the introduction of nanodiamonds, water is prevented from (a) absorbing within the graphene oxide structures, (b) blocking the pathways for hydrogen transport, and (c) irreversibly re–organizing the nanolaminated graphene oxide galleries. Of notable interest, the overall permaselective performance of the membrane was found to exceed that of any reported membrane material performance for the separation of carbon dioxide from hydrogen. For comparison, we surveyed best–in–class performances reported for silicas, polymers and metal and covalent organic frameworks.抄録全体を表示PDF形式でダウンロード (653K) -

ジャーナル 認証ありInduction of curvature in lipid bilayers may lead to increased exposure of hydrophobic membrane core to cell surfaces and the eventual hydrophobic interaction with amphiphilic peptides. Not only physicochemical driving force, the membrane curvature and exposure of the hydrophobic core can be elicited by physiological cellular actions including movement of the cell membrane driven by cytoskeletal F–actin restructuring. This review highlights our findings during our studies on developing curvature–inducing peptides and intracellular IgG delivery peptides.抄録全体を表示PDF形式でダウンロード (830K)

ジャーナル 認証ありLast time, the author described the study of membrane fouling and the transport equation for membrane permeation. This time, the author would like to introduce his research on creating membranes. Polymer membranes and inorganic membranes have been developed. The polymer membranes are negatively and positively charged ultrafiltration membranes, which are polysulfone membranes with sulfonic acid groups and quaternary ammonium groups. The charged membranes have a complex separation mechanism, that is combination of separation by membrane pores and by charge repulsion between the membrane and solute. It was possible to separate not only salts but also various substances such as amino acids, peptides, and proteins. The transport equations of charged membranes were also studied. Inorganic membranes are mainly silica membranes produced by chemical vapor deposition, and zeolite membranes have also been produced, but they will not be introduced here. The author started with low–temperature deposition using ozone, and finally deposited membranes at high temperature (600 ℃) using various silica sources, and was able to obtain high–performance membranes. Since the advantages of inorganic membranes can be applied to membrane reactors, membrane reactors have been applied to steam reforming of methane, dehydrogenation of cyclohexane and methylcyclohexane, and thermal decomposition of hydrogen sulfide. In particular, the cyclohexane dehydrogenation membrane reactor operated continuously for 1,054 hours, and a small membrane reactor equipped with six 50 cm membranes was also developed.抄録全体を表示PDF形式でダウンロード (1062K)

ジャーナル 認証ありIn developing countries, naturally occurring heavy metals contaminate groundwater and are taken into the body as drinking water, resulting in health hazards. We proposed a forward osmosis process using zeolite membranes to remove heavy metals from water. Na–ZSM–5 membrane showed a small solute flux and a high rejection for As, Se and Cr.抄録全体を表示PDF形式でダウンロード (578K) -

ジャーナル 認証ありHighly concentrated particle composite membrane consisting of PIM–1 and surface–modified nanoparticles was developed. The gas permeation properties of the fabricated composite membranes were dependent on the molecular weight of the matrix. The maximum gas permeability of the fabricated composite membranes was 45,000 Barrer. The selectivity of the fabricated composite membranes was maintained. We have succeeded in developing an excellent separation membrane with high permeability.抄録全体を表示PDF形式でダウンロード (610K) -

ジャーナル 認証ありZeta potential is widely used as an indicator of the dispersion stability of colloids. On the other hand, it is also an important quantity in the investigation of solid surface properties. Two main methods for evaluating the zeta potential of solid surfaces are known : the streaming potential method and the electrophoresis method. The principles and practical differences between these two methods will be outlined. The evaluation of fouling and cleaning effects of microfiltration membranes using our SurPASSTM 3 streaming potential measurement system will also be presented.抄録全体を表示PDF形式でダウンロード (782K)
