3D‐Printed Hygroscopic Polymer Networks for High‐Humidity Triboelectric Nanogenerators to Wirelessly Power Implantable Electronic Devices‐ A Conceptual Pathway

Advanced Functional Materials, EarlyView.
This work develops 3D‐printable tribopolymer networks that can enhance triboelectric performance under high humidity environments. Polar hydrophilic functional groups and incorporation of zwitterionic monomers promote bound‐water–dominated interfacial polarization thereby increasing electrical outputs.

Estudio por espectroscopía infrarroja de la reacción de obtención de geles de borosilicato con diferentes relaciones Si/B

Boletín de la Sociedad Española de Cerámica y Vidrio, 2005
Borosilicate gels with different Si/B ratio have been prepared by the sol-gel method. Such gels were obtained by hydrolysis and further condensation of TEOS (tetraethylorthosilicate) and TEB (triethylborate) alkoxides in acidic aqueous media.

Engineering Intelligent Graphene Oxide‐Cellulose Membranes: Suppressing Thermal Runaway for a Safer Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
A novel thermos‐responsive hydroxypropyl cellulose/graphene oxide (HPC/GO) composite membrane is fabricated for reversible temperature‐gated ion transport in aqueous zinc‐ion batteries. Enabled by LCST‐driven structural transition, unimpeded ion diffusion at room temperature delivers high capacity, while elevated temperature suppresses transport; full ...

Self‐Healing and Stretchable Synaptic Transistor

Advanced Functional Materials, EarlyView.
A self‐healing stretchable synaptic transistor (3S‐T) is realized using a p‐PVDF‐HFP‐DBP/PDMS‐MPU‐IU bilayer as gate insulator, where dipole‐dipole interaction enhances polarization to achieve a large memory window. Leveraging its neuronal biomimicry, the synaptic transistor demonstrates electrically compatibility with the biological brain. Furthermore,

Analysis of lard in cream cosmetics formulations using FT-IR spectroscopy and chemometrics [PDF]

, 2011
Typically, cream preparation is composed from complex mixtures; therefore its analysis is rather difficult. The presence of lard (LD) in any personal care products is prohibited to be used by the Followers of Islam.
