Small Structures, Volume 7, Issue 7, July 2026.This review highlights how PLLA's molecular chirality and noncentrosymmetric chain packing generate intrinsic shear piezoelectricity without electrical poling, while crystallinity, optical purity, and molecular orientation define its design space. By distinguishing intrinsic d14 from device‐level outputs and connecting processing strategies to tissue ...

Micro-machined membrane deformable mirrors for cryogenic adaptive optics [PDF]
, 2002 In this Thesis, the suitability of 37 actuator Micro-machined membrane deformable mirrors (MMDM) for adaptive optics at cryogenic temperatures is evaluated. A method is described to safely cool MMDMs to 78K. The initial surface figures of three MMDMs are

British Journal of Pharmacology, Volume 183, Issue 13, Page 3780-3795, July 2026.Receptor‐induced Kv7/M‐current suppression increases neuronal activity and contributes to pathology of several conditions. A new class of Kv7 modulators identified in this study attenuates M‐current suppression and shows therapeutic effects. Abstract Background and Purpose Neuronal Kv7 channels generate low voltage–gated potassium currents known as the

Matching optics for Gaussian beams [PDF]
, 1991 A system of matching optics for Gaussian beams is described. The matching optics system is positioned between a light beam emitter (such as a laser) and the input optics of a second optics system whereby the output from the light beam emitter is ...

A Comparison of Acoustic Field Measurement by a Microphone and by an Optical Interferometric Probe
Acta Polytechnica, 2002 The objective of this work is to show that our optical method for measuring acoustic pressure is in some way superior to measurement using a microphone. Measurement of the integral acoustic pressure in the air by a laser interferometric probe is compared
