Incorporation of cobalt ferrite on the field dependent performances of magnetorheological grease

Journal of Materials Research and Technology, 2020
Magnetorheological grease (MRG) is one of the smart materials that experiences a high off-state viscosity, which hassles the operation of devices at the beginning and causes more energy consumption upon operation.

A lung targeted miR-29 mimic as a therapy for pulmonary fibrosis

EBioMedicine, 2022
Summary: Background: MicroRNAs are non-coding RNAs that negatively regulate gene networks. Previously, we reported that systemically delivered miR-29 mimic MRG-201 reduced fibrosis in animal models, supporting the consideration of miR-29-based therapies

Fluxional Monomers Remodel Crystallinity at Low Loadings in Diketopyrrolopyrrole Co‐Thienothiophene Conjugated Polymers

Angewandte Chemie, EarlyView.
Bullvalene is a fluxional molecule capable of adopting numerous conformations spontaneously; just like a Rubik's Cube. In this paper, we explore the incorporation of bullvalene into the backbone of a highly rigid conjugated polymer semiconductor and observe that the inherent fluxionality reduces average crystallite size.

The first observational evidence of a mixed Rossby–gravity wave contribution to triggering the onset process of the South China Sea summer monsoon

Environmental Research Letters, 2023
Convectively coupled equatorial waves (Kelvin waves, equatorial Rossby waves, the Madden–Julian Oscillation, tropical depression–type waves, and mixed Rossby–gravity (MRG) waves) are important components of the tropical atmosphere.
