Membranes for Artificial Kidney

Kobunshi, 1972
人工腎に用いられる膜は,その発祥から現在に至るまで一貫してセルロース膜である。この王座は当分動きそうにない。ではいまのcuprophane膜に満足しているのかといえば,決してそうではない。透過性・強度いずれの点でも不満が多い。他の膜が提供されないから, できの悪いcuprophaneでガマンしているというのが現状である。新しい膜を開発する研究も数多く行なわれている。どれも実用化に至らないのは, 個々の点ですぐれていても総合点になるとcuprophaneより卓越したものがないからである。透過性の点はともかく, ダイアライザーという特殊構造に組み入れられたときの機械的強度に難点のあることが多い。新しい膜の中で実用化に近い点まで達しているのは,いずれも天然高分子(セルロース, コラーゲン) の膜である ...

Topology and energy transport in networks of interacting photosynthetic complexes [PDF]

, 2012
We address the role of topology in the energy transport process that occurs in networks of photosynthetic complexes. We take inspiration from light harvesting networks present in purple bacteria and simulate an incoherent dissipative energy transport ...

Phase transitions in biological membranes

, 2018
Native membranes of biological cells display melting transitions of their lipids at a temperature of 10-20 degrees below body temperature. Such transitions can be observed in various bacterial cells, in nerves, in cancer cells, but also in lung ...

High‐Performance Low‐Emissivity Paints Enabled by N‐Doped Poly(benzodifurandione) (n‐PBDF) for Energy‐Efficient Buildings

Advanced Functional Materials, EarlyView.
This study introduces a scalable and colored low‐emissivity (low‐e) paint achieved by spraying an ultrathin n‐doped poly(benzodifurandione) (n‐PBDF) coating onto various colored substrates. The low‐e paint enhances thermal regulation by reducing mid‐infrared thermal emissivity to 0.19, thereby stabilizing indoor temperatures across diverse climates ...

Modeling Amyloid Beta Peptide Insertion into Lipid Bilayers [PDF]

, 2004
Inspired by recent suggestions that the Alzheimer's amyloid beta peptide (A beta) can insert into cell membranes and form harmful ion channels, we model insertion of the 40 and 42 residue forms of the peptide into cell membranes using a Monte Carlo code ...

Biointerfacing with AgBiS2 Quantum Dots for Pseudocapacitive Photostimulation

Advanced Functional Materials, EarlyView.
It is demonstrated that AgBiS2 quantum dots exhibit unique photoinduced pseudocapacitive charge transfer properties, enabling efficient light‐to‐electrical energy conversion. These quantum dots facilitate enhanced light absorption and transduction when integrated with ZnO nanowires, which serve as an effective charge transport medium.
