High Performance, Flexible, Solid-State Supercapacitors Based on a Renewable and Biodegradable Mesoporous Cellulose Membrane

High Performance, Flexible, Solid‐State Supercapacitors Based on a Renewable and Biodegradable Mesoporous Cellulose Membrane

A renewable, flexible, and degradable mesoporous cellulose membrane is prepared using a facile and scalable approach, and exhibits rational capacitance and excellent cyclability used in solid-state energy storage devices. A simple yet smart integrated design of micro-supercapacitors is also developed by directly depositing the electrode materials on the membrane-based polymer electrolyte without the use of binder or complicated setups.

Porous Poly(Ionic Liquid) Membranes as Efficient and Recyclable Absorbents for Heavy Metal Ions

Porous Poly(Ionic Liquid) Membranes as Efficient and Recyclable Absorbents for Heavy Metal Ions

Porous poly(ionic liquid) (PIL) membranes are synthesized via in situ photo-crosslinking of vinyl imidazole with both hydrophilic and hydrophobic ionic liquid monomers. The prepared PIL membranes show high metal ion absorption capacity, and can be easily recycled.

Enhancement of Growth of MOF MIL-68(Al) Thin Films on Porous Alumina Tubes Using Different Linking Agents

Enhancement of Growth of MOF MIL‐68(Al) Thin Films on Porous Alumina Tubes Using Different Linking Agents

MIL-68(Al) thin membranes are prepared on cylindrical alumina supports. Different kinds of binders or linking agents (colloidal silica LUDOX®, silicalite-1, and chitosan) are used to promote the growth of MOF crystals. Single-gas permeation experiments are carried out to study the quality and efficiency of the membranes.

Photocatalytic Nanofiltration Membranes with Self-Cleaning Property for Wastewater Treatment

Photocatalytic Nanofiltration Membranes with Self‐Cleaning Property for Wastewater Treatment

A photocatalytic nanofiltration membrane (NFM) with self-cleaning capability is fabricated via a facile biomimetic mineralization process. In visible light, this membrane exhibits efficient photocatalytic activity for degrading dyes through the photo-Fenton reaction concurrently with effective nanofiltration performance. The as-prepared NFM shows great potential in advanced textile wastewater treatment with satisfactory stability.

Enhancement of Oxygen Activation and Mobility in CaTixFe1−xO3−δ Oxides

Enhancement of Oxygen Activation and Mobility in CaTixFe1−xO3−δ Oxides

On the move: Oxygen mobility, as evaluated by oxygen isotopic exchange, is lower in CaTi0.9Fe0.1O3−δ than in CaTi0.8Fe0.2O3−δ. This difference in activity disappears if CaTi0.9Fe0.1O3−δ is associated with LaMnO3 in a dual-bed system. Only a small amount of manganite favors oxygen activation on CaTi0.9Fe0.1O3−δ and contact between the two beds, which results in a triple-phase boundary that is not indispensable.

Broad Spectrum Macromolecular Antimicrobials with Biofilm Disruption Capability and In Vivo Efficacy

Broad Spectrum Macromolecular Antimicrobials with Biofilm Disruption Capability and In Vivo Efficacy

Biodegradable eight membered polycarbonates that exhibit broad spectrum antimicrobial activity are synthesized by organocatalytic ring-opening polymerization. These materials are nonhemolytic and nontoxic with the ability to lyse individual microbes or biofilm via membrane lytic mechanism. In a blood stream infection mouse model, the polymer, injected intravenously, removes bacteria from the blood more rapidly than the antibiotic Augmentin without causing toxicity.

Coordinating Biointeraction and Bioreaction of a Nanocarrier Material and an Anticancer Drug to Overcome Membrane Rigidity and Target Mitochondria in Multidrug-Resistant Cancer Cells

Coordinating Biointeraction and Bioreaction of a Nanocarrier Material and an Anticancer Drug to Overcome Membrane Rigidity and Target Mitochondria in Multidrug‐Resistant Cancer Cells

A nanocomposite of binary lipids and polymer with anticancer prodrug mitomycin C (MMC) (MMC-DHA-PLN) is designed to overcome multifaceted drug resistance. It first utilizes the biointeraction of nanomaterial docosahexaenoic acid (DHA) to facilitate cellular uptake of the nanoparticle-encapsulated MMC, and then synchronizes intracellular activation of MMC and lipid peroxidation of DHA to damage mitochondria, leading to enhanced anticancer efficacy in vitro and in vivo.

Highly Efficient Virus Rejection with Self-Organized Membranes Based on a Crosslinked Bicontinuous Cubic Liquid Crystal

Highly Efficient Virus Rejection with Self‐Organized Membranes Based on a Crosslinked Bicontinuous Cubic Liquid Crystal

Virus rejection by a liquid crystal membrane is realized for the first time using a self-assembling mesogen stabilized by crosslinking in an ordered bicontinuous cubic phase. This structure allows for the level of control over pore size distribution necessary for efficient rejection of small particles including viruses while allowing for permeation of water. Applying pressurization to the membrane prior to testing results in improved virus removal efficiency and water flux.

A Charge Reversible Self‐Delivery Chimeric Peptide with Cell Membrane‐Targeting Properties for Enhanced Photodynamic Therapy

An easy-to-fabricate charge reversible self-delivery chimeric peptide is developed to realize cell membrane targeted photodynamic therapy (PDT). Under light irradiation, C16––PRP–DMA can directly disrupt the cell membrane and rapidly induce cell necrosis, which remarkably increases the PDT effect.

Control of Cell Alignment and Morphology by Redesigning ECM‐Mimetic Nanotopography on Multilayer Membranes

Flexible and freestanding biomimetic multilayer membranes, which topography resemble the nanofeatures of the extracellular matrix, are successfully developed using a friendly user layer-by-layer technology. The ability to crosslink with genipin as well as the presence of a patterned topography on the surface of the natural-based membranes provides a promising system to tailor cellular behavior including cell alignment and differentiation.

Planarizable Push–Pull Probes: Overtwisted Flipper Mechanophores

Overengineering? Small structural changes related to the deplanarization of a fluorophore based on the dithienothiophene dimer lead to a complete loss of mechanosensitivity of this probe when it is integrated in lipid bilayer membranes; however, nanoparticles of this material are fluorescent in water.
