Untethered Autonomous Holonomic Mobile Micromanipulator for Operations in Isolated Confined Spaces

Advanced Intelligent Systems, EarlyView.
Herein, a lightweight (515 g), compact (10 cm3), untethered holonomic mobile micromanipulator powered by piezoelectric actuators is presented. It autonomously manipulates mm to sub‐mm objects and droplets in narrow, hazardous spaces, achieving 0.18 ± 0.51 mm positioning accuracy and −0.4° ± 1.2° angular deviation.

Solvent‐Free Process for Preparing Metal‐Organic Framework Composites Based on Carbon‐Based Quantum Dots and Their Derivatives as Drug Delivery Systems for Andrographolide

Chemistry – A European Journal, EarlyView.
Andrographolide (ADG) was conjugated with MOFs (MIL‐53(Al), ZIF‐8) carbon‐based quantum dots (CBQDs) and doped carbon‐based quantum dots (D‐CBQDs) using the green approach of high‐pressure (0.3 GPa) solid phase contact. This method enhances the drug solubility, as indicated by changes in hydrophobicity observed via 1H NMR. Abstract Andrographolide (ADG)

Study on acoustic radiation impedance at aperture of a waveguide with circular cross section taking account of interaction between different guided modes [PDF]

arXiv, 2014
In this paper we simulated self- and mutual- acoustic impedances of guided modes at the aperture and estimated accuracy of the piston radiation approximation. We used the Rayleigh integral to simulate the interactions between different guided modes at the aperture, with low time-consuming.

Optical Communication Channel in Systems for Measurement of Parameters of the Internal Combustion Engine Piston

Bulletin of Kalashnikov ISTU, 2016
The use of a telemetric system with an optical communication channel is considered for obtaining information on piston parameters. The structure of an optical communication channel is described, and also the possible errors in the transfer of an optical signal through the intermediate environment are considered.
