Regioselective and Anisotropic Multi‐Patching of Small Microparticles via a Polymer Brush‐Assisted Microcontact Printing (µCP)

open access: yesAdvanced Functional Materials, EarlyView.
A method to fabricate anisotropic SiO2 patchy microspheres is presented using a modified microcontact printing technique. This involves a PDMS elastomer stamp with grooved surface topography, creating a confined environment for the microspheres.

Simple Mechanical Equivalents of Stepping Rotary Dynamics in F$_1$-ATPase [PDF]

open access: yesarXiv, 2002
Two simple (rotator and one-particle) mechanistic models are suggested to describe simultaneously at a minimal level of sophistication two basic functions of F$_1$-ATPase: a motor regime driven by ATP hydrolysis and its inverted function as ATP synthesis.

Light‐Mediated Photomultiplication via Cascade Energy Transfer in Organic Photodiode

open access: yesAdvanced Functional Materials, EarlyView.
Light‐mediated photomultiplication via cascade energy transfer in organic photodiode demonstrates external quantum efficiency exceeding 200% and specific detectivity surpassing 5.0 × 1013 Jones. This advancement effectively addresses the limitation of elevated dark current density characteristic of prior photomultiplication organic photodetectors ...

A Homeostatic Photonic Device Integrating Vapor‐Regulated Thermo‐Optical Feedback Mechanisms

open access: yesAdvanced Functional Materials, EarlyView.
An inorganic homeostatic photonic device is designed to autonomously regulate light, temperature, and vapor sorption through integrated positive and negative feedback mechanisms at multiple wavelengths. The device uses a graded mesoporous 1D photonic crystal coupled with a photothermal layer.

Transition to Chaos in the Kinetic Model of Cellulose Hydrolysis Under Enzyme Biosynthesis Control [PDF]

open access: yesarXiv, 2017
In the paper the kinetic model of the biochemical process of cellulose hydrolysis with cell application is presented. The model includes enzyme biosynthesis control and is open conditions it represents the dynamical system in the preturbulent regime. The limit cycle and its five consequence bifurcations of the doubling-period type are found.
