Butterworth pattern based simultaneous damping and tracking controller designs for nanopositioning systems

Frontiers in Mechanical Engineering, 2016
The Butterworth filter is known to have maximally flat response. Incidentally, the same response is desired in precise positioning systems. This paper presents a method for obtaining a closed-loop Butterworth filter pattern using common control schemes ...

Asymmetrically Nonlinear Generation of Optical Orbital Angular Momentum via Cooperation of Bragg Diffraction and Birefringent Phase Matching

Laser &Photonics Reviews, Volume 20, Issue 2, 22 January 2026.
Nonlinear orbital angular momentum (OAM) manipulation is crucial for fundamental physics and information technologies. An integrated lithium niobate platform combining Bragg diffraction and birefringent phase matching asymmetrically generates and controls second‐harmonic OAM beams, achieving a normalized conversion efficiency of 10−2 W−1 and supports a

Single‐Source Cyanurate Precursor for Making Manganese Carbodiimide and the Second Harmonic Generation Effect of the Intermediate Manganese Monohydrocyanurate Mn(HC3N3O3)

European Journal of Inorganic Chemistry, Volume 28, Issue 36, December 15, 2025.
The thermal conversion of the single‐source precursor Mn(H2C3N3O3)2(H2O)4 reveals a sequence of new compounds. One intermediate compound is the second‐harmonic‐generation‐active Mn(HC3N3O3) (MHCY) that appears before pure Mn(CN2) is formed. Two manganese cyanurate compounds, Mn(H2C3N3O3)2(H2O)4 and Mn(H2C3N3O3)2(H2O)7 were prepared and structurally ...

Millikelvin Intracellular Nanothermometry with Nanodiamonds

Advanced Science, Volume 12, Issue 45, December 4, 2025.
Nanothermometry in living cells is crucial for understanding heat diffusion and advancing cellular biology and drug discovery. Previous studies have reported controversial intracellular temperature variations. Using nanodiamond nanothermometry in macrophages, it is found that, in such experimental setting, apparent temperature changes are actually due ...
