Direct Evidence of Topological Dirac Fermions in a Low Carrier Density Correlated 5d Oxide

open access: yesAdvanced Functional Materials, EarlyView.
The 5d oxide BiRe2O6 is discovered as a low‐carrier‐density topological semimetal hosting symmetry‐protected Dirac fermions stabilized by nonsymmorphic symmetries. Angle‐resolved photoemission spectroscopy, quantum oscillations, and magnetotransport measurements reveal gapless Dirac cones, quasi‐2D Fermi surfaces, high carrier mobility, and a field ...

Self‐Immolative Activatable Nanoassembly toward Immuno‐Photodynamic Therapy in TME

open access: yesAdvanced Functional Materials, EarlyView.
A quinone methide‐gated, self‐immolative, H2O2‐responsive nano‐photosensitizer (Pyz/PS) is developed for targeted immuno‐photodynamic therapy. Pyz/PS selectively activates within tumor microenvironments, restores photosensitizer activity, generates ROS, and depletes intracellular GSH, enhancing oxidative stress.

On the stability of a particular class of one-dimensional states of dynamic equilibrium of the Vlasov–Poisson electron gas

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки
The one-dimensional problem of the linear stability of dynamic states of local thermodynamic equilibria with respect to small perturbations was studied for the case when the Vlasov–Poisson electron gas contains electrons with a stationary distribution ...

Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

Block Copolymer Microcapsules with Perpendicularly‐Perforated Ultrathin Membranes for Controlled Transmembrane Transport

open access: yesAdvanced Functional Materials, EarlyView.
Block copolymer microcapsules with ultrathin, perpendicularly perforated membranes are developed through double emulsions, initiated by the diffusion of water into single emulsions. Both shell thickness and channel diameter can be systematically tuned, offering precision in molecular sieving and significantly enhanced permeation rates.

Numerical Simulation on Self-Propulsion Characteristics of Bionic Flexible Foil Considering Ground Wall Effect

open access: yesBiomimetics
In order to figure out the wall effect on the propulsive property of an auto-propelled foil, the commercial open-source code ANSYS Fluent was employed to numerically evaluate the fluid dynamics of flexible foil under various wall distances.
