BioCNTs Mediated Delivery of Systemically Mobile Small RNAs via Leaf Spray to Control Both Tomato DNA and RNA Viruses

Advanced Science, EarlyView.
A carbon nanotube‐based biopesticide system (BioCNTs) enables efficient delivery and systemic movement of RNAi molecules to control major tomato viruses. By integrating shRNA and tRNA‐like structures (TLS) with BioCNTs, this green and scalable approach achieves long‐term silencing and high antiviral efficacy through simple foliar spraying.

Implementation of a Controller to Eliminate the Limit Cycle in the Inverted Pendulum on a Cart

Complexity, 2019
A frequency response-based linear controller is implemented to regulate the inverted pendulum on a cart at the inverted position. The objective is to improve the performance of the control system by eliminating the limit cycle generated by the dead-zone,

Chromatin Topology Reconfiguration Orchestrates Thermotolerant Male Fertility via GhAL5 in Cotton

Advanced Science, EarlyView.
This study investigates cotton’s high‐temperature (HT) response using multi‑omics. Dynamic 3D genome changes drive expression bias affecting male fertility. The tolerant line shows controlled chromatin dynamics, while the sensitive line exhibits overactivation.

Carbon-Supported Platinum Molybdenum Electro-Catalysts and Their Electro-Activity Toward Ethanol Oxidation

International Journal of Electrochemical Science, 2011
We synthesized and studied a series of carbon-supported PtMo catalysts with a 20% metal loading as active phase. The analysis was made with three atomic ratios in the active phase, Pt-Mo: 1-1, 7-3 and 3-1.
