Biphasic Co‐Delivery of Curcumin and 5‐FU using 3D‐Printed Dissolving Microneedles for Skin Cancer Therapy

Advanced Healthcare Materials, EarlyView.
Using pixel‐aware digital light processing, the authors created high‐resolution, dissolvable microneedles from a PEGDA/VP matrix. These microneedles encapsulate curcumin and 5‐fluorouracil and dissolve in the skin, co‐delivering drugs directly to tumours.

A DDS-PLL hybrid based fast settling wideband frequency synthesizer for frequency hopping radios

Procedia Computer Science, 2017
Abstract The new generation software defined radios implement a wideband RF front-end which calls for a wideband frequency synthesizer for generating the local oscillator signal. Moreover military applications demands frequency hopping capability also.

Polyimide‐Linked Hexaazatriphenylene‐Based Porous Organic Polymer with Multiple Redox‐Active Sites as a High‐Capacity Organic Cathode for Lithium‐Ion Batteries

Advanced Materials, EarlyView.
A high‐capacity polyimide‐linked porous organic polymer (HAT‐PTO) incorporating numerous redox‐active centers is synthesized via a hydrothermal reaction, delivering a high theoretical capacity of 484 mAh g−1. In situ hybridization with carboxyl‐functionalized multiwalled carbon nanotubes enhances conductivity and stability, achieving 397 mAh g−1 at C ...

Impact of Grid Strength on the Transient Dynamics of Droop- and VSM-Based Grid-Forming Converters

International Transactions on Electrical Energy Systems
With the increasing use of converter-based resources, it has become more crucial to comprehend the dynamic interaction between grid-forming (GFM) control strategies and power system transients under different grid strengths.

Frequency Response Enhancement of an Islanded Hydro Turbine-Based Microgrid Using Battery Storage and Adaptive Predictive Control

IEEE Access
Hydraulic turbine generators (HTG) inherently exhibit slow dynamic responses; therefore, when operating as the sole power source in an islanded microgrid (MG), they may be unable to comply with the frequency limits imposed by existing grid codes for ...

Room‐Temperature Skyrmionic Synapse in 2D Ferromagnet Fe3GaTe2 Operating via Collective Spin Texture Transformation

Advanced Materials, EarlyView.
We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.

Effects of nonlinearities from the analog frequency-ramps of the fast network-analyser [PDF]

Advances in Radio Science, 2003
The developed network analyser with four ports allows very fast measurements of S-parameters in comparison with a conventional network analyser. This is possible because highly linear analogue frequency ramps are used.

Azobenzene's Cross‐Scale Optics and Photonics: Molecular Photoswitching, Mesoscopic Material Motions, and Adaptive Devices

Advanced Materials, EarlyView.
Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...
