Rapid and Reversible Morphing to Enable Multifunctionality in Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
This article introduces a rapid, reversible, and repeatable morphing robot through a bistable latch‐mediated, spring actuated (LaMSA) mechanism. This enables an untethered, multifunctional robot to near‐instantaneously (< 50 ms) and reversibly switch between a flying and driving configuration to navigate through different environments.

A Perturbative Approach to the Redshift Space Correlation Function: Beyond the Standard Model

open access: yes, 2017
We extend our previous redshift space power spectrum code to the redshift space correlation function. Here we focus on the Gaussian Streaming Model (GSM). Again, the code accommodates a wide range of modified gravity and dark energy models.

Efficient and Fast Microplastic Separation From Aqueous Media by Electron Beam Assisted Developed Superhydrophobic Jute Fabric

open access: yesJournal of Applied Polymer Science, EarlyView.
Efficient and fast microplastic separation from aqueous media by superhydrophobic jute fabric. ABSTRACT The accumulation of microplastics (MPs) in various aquatic environments is an alarming problem in the modern world. Hydrophobic surfaces are potential candidates to remove microplastics from water.
