DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

open access: yesAdvanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Pskov Chronicles on the History of Russian-Horde Relations

open access: yesRUDN Journal of Russian History
The author examines the Pskov Chronicle collections, written in the 15th century, towards the end of and after the end of the yoke of the Golden Horde. These chronicles represent not only a separate layer of information on the history of the Golden Horde

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

open access: yesAdvanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

The amazing synchronicity of the Global Development (the 1300s-1450s). An institutional approach to the globalization of the late Middle Ages [PDF]

open access: yes, 2010
In a new approach to a long-ranging debate on the causes of the Late Medieval Debasement, we offer an institutional case-study of Russia and the Levant.

An Engineered Living Material With Pro‐Angiogenic Activity Inducible by Near‐Infrared Light

open access: yesAdvanced Functional Materials, EarlyView.
NIR‐responsive engineered living materials (ELMs) for controlled angiogenesis: Near‐infrared (800 nm) light activates engineered probiotic bacteria within alginate‐based living materials to secrete a blood vessel‐regenerating protein. The released protein promotes pro‐angiogenic effects in endothelial networks and chick chorioallantoic membranes.

Shaping of Biohybrid Functional Living Materials

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates a strategy for shaping living mycelium into functional materials by directing its natural growth. Nanoparticles armor hyphae, micron‐scale particles entangle within the network, and printed hydrogel architectures steer expansion, creating defined geometries.

Polymer Infiltration Into SURMOF Channels Enables Hydrophobic and Solid‐Like Slippery Functional Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
We report a polymer‐chain insertion strategy to fabricate pore‐threaded MOF thin films with precisely tuned surface chemistry and wettability. Grafting n‐alkane chains into the pillared layer Cu2(bdc)2(dabco) MOF thin film's vertical nanochannels enhances water stability, and induces hydrophobicity and lubricant‐free, solid‐like slippery behavior ...

Bone Remains of Birds from the Central Part of the Bolgar Fortified Settlement

open access: yesАрхеология евразийских степей
The remains of birds from the CLXXIX excavation site in the central part of the Bolgar fortified settlement of the pre-Mongol, early and late Golden Horde periods were studied. The total number of identified species is 32.
