Electrochemical Biosensor for Rapid Detection of Acute Rejection in Kidney Transplants

Advanced Healthcare Materials, EarlyView.
A low‐cost, rapid electrochemical immunosensor coated with a novel antifouling nanocomposite enables single‐step, dual‐biomarker profiling directly from unprocessed urine. Application in a clinical study shows accurate discrimination of acute rejection in kidney transplants from other acute kidney injuries via machine learning.

Robust chaos-based stream-cipher for secure public communication channels

International Conference for Internet Technology and Secured Transactions, 2016
In this paper, we propose a novel stream cipher based on a chaotic system. In order to get the cipher text, the plain text is simply XORed with the key-stream generated by a strong pseudo chaotic number generator (PCNG).

A Ship‐in‐a‐Bottle Strategy: Crosslinking Amines and Epoxides inside MOF Pores for Enhanced CO2 Capture Performance

Advanced Materials, EarlyView.
A “ship‐in‐a‐bottle” strategy is used to grow oligomers inside of a MOF by crosslinking alkylamines with epoxides within the pores of Cr‐BDC. When tested in postcombustion carbon capture applications, the composites show excellent performance with high CO2 adsorption capacity, exceptional CO2/N2 selectivity, and enhanced stability over 100 adsorption ...

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

Advanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.
