Overcoming intranasal delivery barriers with ultrastable polyzwitterionic siRNA nanocages for enhanced glioblastoma therapy

BMEMat, EarlyView.
A ROS‐responsive, zwitterionic nanocage enables stable, intranasal siRNA delivery to glioblastoma, promoting deep tumor penetration via non‐degradative pathways and trigeminal nerve transport. This platform achieves durable gene silencing and tumor suppression, offering a non‐invasive, storage‐stable strategy for treating glioma and other neurological ...

Carrier‐free self‐assembled nanomedicine for combination‐therapy of acute myeloid leukemia

BMEMat, EarlyView.
CPDS combines drugs with three different mechanisms of action to achieve a multi‐mechanism combination therapy for AML by directly killing tumor cells and activating anti‐tumor immunity. Abstract As the main acute myeloid leukemia (AML) clinical treatment, the chemotherapy alone cannot meet the clinical therapeutic needs due to the high heterogeneity ...

Amorphous Protective Layers to Reshape Inorganic‐Rich Interphases for High‐Voltage Sodium‐Ion Batteries

Carbon Energy, EarlyView.
Herein, we propose a straightforward and efficacious strategy of surface modification for P2‐type Na0.7Li0.03Mg0.03Ni0.27Mn0.6Ti0.07O2 cathode in high‐voltage Na‐ion batteries. The stable amorphous SiO2 coating layer on the cathode surface contributes to a strong, dense, fluorine and silicon‐rich cathode–electrolyte interphase, which inhibits the side ...

FeCl3 doped polyvinylidene fluoride

Journal of Materials Science, 1994
Infrared (350-4000 cm -1) and optical (1.1 5 x 1 04 - 2.95 x 1 04 cm -1) spectra, differential thermal analysis (DTA) and d.c. electrical resistivity of FeCI3- doped polyvinylidene fluoride (PVDF) films, over the doping mass fraction range 0 ~< w ~< 0.40, have been measured. The i.r. spectra provided evidence of: (a) the presence of both ~ and y phases

Ferroelectricity in polyvinylidene fluoride

Journal of Applied Physics, 1978
Changes induced in the orientation of the axes of crystallites in thin films of polyvinylidene fluoride by the application of 6×107 V/m at 100 °C for 1/2 h have been observed. The changes were observed by measuring the intensity of x rays diffracted from the film as a function of the orientation of the film relative to the diffracting x-ray beam.

Pyroelectricity in polyvinylidene fluoride

Journal of Applied Physics, 1973
The pyroelectric behavior of as-received 2-mil polyvinylidene fluoride films was studied as a function of the poling treatment. It is shown that poling induces a thermally reversible electric polarization in addition to an electric polarization which vanishes upon the first heating of the sample.

Pyroelectricity in polyvinylidene fluoride

Journal of Applied Physics, 1979
The magnitude of the pyroelectric coefficient in polyvinylidene fluoride was observed to increase significantly on maintaining the poling field while cooling the samples from elevated poling temperatures to ambient temperature. The results of the measurement of the depolarization currents with repeated thermal cycling of poled specimens from ...

Force induced piezoelectric effect of polyvinylidene fluoride and polyvinylidene fluoride-co-trifluoroethylene nanofibrous scaffolds

The International Journal of Artificial Organs, 2018
Polyvinylidene fluoride and its co-polymer with trifluoroethylene are promising biomaterials for supporting nerve regeneration processes because of their proven biocompatibility and piezoelectric properties that could stimulate cell ingrowth due to electrical activity upon mechanical deformation.
