Using the cylindrical rod method and a vector network analyzer to determine the dielectric permittivity of materials on microwave range

open access: yesDoklady Belorusskogo gosudarstvennogo universiteta informatiki i radioèlektroniki, 2019
It's considered the way in which the method of a cylindrical rod together with a vector network analyzer is used to determine the dielectric constant. The algorithm for determining the dielectric constant is developed.

Machine Learning‐Enabled Polymer Discovery for Enhanced Pulmonary siRNA Delivery

open access: yesAdvanced Functional Materials, EarlyView.
This study provides an efficient approach to train a machine learning model by merging heterogeneous literature data to predict suitable polymers for siRNA delivery. Without the need for extensive laboratory synthesis, the machine learning enabled a virtual screening and successfully predicted a polymer that is validated for effective gene silencing in

Regulating the Interphase Strain in High‐Entropy Oxide Thin Films – An Approach to Attaining Giant Energy Storage Capability under Moderate Electric Fields

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates an interphase strain engineering strategy to regulate capacitive energy storage performance in high‐entropy oxide thin films. Through introducing pyrochlore nanocolumns, the polarization response of perovskite unit cells is strengthened, yielding recoverable energy densities up to 93 J cm−3 with an efficiency of 83% under ...
