A novel aureothin diepoxide derivative from Streptomyces sp. NIIST-D31 strain
The Journal of Antibiotics, 2022A novel vicinal diepoxide of alloaureothin was isolated from Streptomyces sp. NIIST-D31 strain along with three carboxamides, p-aminobenzoic acid and 1,6-dimethoxyphenazine. Exhaustive 2D NMR analysis and analysis of experimental, theoretical CD spectra aided in establishing the structure of compound 1. Compound 1 inhibits adipogenesis and accumulation

Equivalent homogeneous model of D31-mode longitudinal piezoelectric transducers
Journal of Intelligent Material Systems and Structures, 2017This article focuses on modelling of D31-mode longitudinal piezoelectric transducers. A simple equivalent one-dimensional homogeneous model of D31-mode longitudinal piezoelectric transducers is proposed in this article. Homogeneous properties of the model are derived by a simple analytical mixing method based on the operation principle of D31-mode ...

Simulating the Effects of Porosity on the D31 Piezoelectric Coefficient of Polyvinylidene Fluoride
ASME 2022 Conference on Smart Materials, Adaptive Structures and Intelligent Systems, 2022Abstract A piezoelectric, thin film polyvinylidene fluoride (PVDF) material was developed for application as a blood pressure/flow sensor within an artificial heart. In an effort to increase the piezoelectric coefficient, d31, and maximize the sensitivity of the PVDF material, nanoscale pores were introduced into the thin films.

An Attempt to Topology Optimize 3D Printed Piezoelectric Composite Sensors for Highest D31 Output
ASME 2021 Conference on Smart Materials, Adaptive Structures and Intelligent Systems, 2021Abstract By adopting topology optimization based on numerical solvers, the geometries of the piezoelectric sensors can be optimized to produce higher electrical output in a certain loading directions. 2D topology optimization and simulation studies are carried out with ANSYS using Piezo and MEMS extensions for coupled systems.

Simulations, fabrication, and characterization of d31 mode piezoelectric vibration energy harvester
Microsystem Technologies, 2019This paper presents the development work on d31 mode piezoelectric vibration energy harvester. The device structure consists of a fixed-free type cantilever beam with a seismic mass attached at the free end of the beam. On top of the cantilever beam, a ZnO piezoelectric layer is sandwiched between two metal electrodes.

Zaštita od buke cestovnog prometa na dionici ceste D31 - spoj D31 na D30 i na D408
2010Za dionicu ceste D31 – spoj na D30 i na D408 izrađen je idejni projekt zaštite od buke. Izrađen je 3D modela prostora za navedenu dionicu. Primjenom računalnog programa LIMA koristeći njemačku i francusku metodu proračuna određene su razine buke. Predviđena vrsta zaštite su zidovi za zaštitu od buke za koje je izvršena optimizaciju njihovih visina i ...
