Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

open access: yesAdvanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Fusogenic RNA Nanomodules for Fusion‐Mediated and Multiplexed siRNA Delivery

open access: yesAdvanced Functional Materials, EarlyView.
A fusogenic lipid‐layered RNA nanomodules (L‐CRAMs) enable high‐capacity and long‐lasting siRNA delivery through membrane fusion. These nanomodules carry exceptionally large siRNA payloads, avoid conventional endosomal uptake, and release multiple functional siRNAs through Dicer‐mediated processing.

Results of research on determining the coefficient of rolling resistance of the wheel by the rollback method

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
AbstractThe simultaneous rolling process of two identical wheels in the driving and braking modes is simulated, taking into account the rollback process. The processes of interaction of the driving and braking wheels of the same size with each other and with the mobile platform (road) separating them are studied.

Disentangling Bulk and Surface Contributions to Charge and Discharge Fading in High‐Voltage LiCoO2

open access: yesAdvanced Functional Materials, EarlyView.
High‐voltage operation of LiCoO2 accelerates capacity fading through bulk and surface degradation. By introducing a LiTaO3 coating to selectively suppress surface degradation, bulk and surface contributions to charge and discharge fading are decoupled.

Road surface influence on tyre/road rolling resistance

open access: yes, 2011
Rolling resistance is a form of energy loss caused by the interaction between a rolling tyre and the road surface. This functional property of road surfaces and also of tyres is one of the most important from both an economical and environmental point of
