Advanced analysis of fully-printed organic transistors platform for multi-ion detection in sweat

Danick Briand, Xi Chen, Silvia Demuru, Jaemin Kim, Brince Paul Kunnel

Organic electrochemical transistors are emerging as prominent biochemical sensors for multi-sensing, including ions, metabolites, hormones, or viruses. However, the implementation of the devices is mainly limited to a single-analyte detection and a single- ...

Correlated insulator collapse due to quantum avalanche via in-gap ladder states

Xi Chen, Camille Didier Georges Aron

The significant discrepancy observed between the predicted and experimental switching fields in correlated insulators under a DC electric field far-from-equilibrium necessitates a reevaluation of current microscopic understanding. Here we show that an elec ...

Dopaminergic neurodegeneration induced by Parkinson's disease-linked G2019S LRRK2 is dependent on kinase and GTPase activity

Elpida Tsika, Darren Moore, Xi Chen

Mutations in leucine-rich repeat kinase 2 (LRRK2) are the most common cause of late-onset, autosomal-dominant familial Parkinson's disease (PD). LRRK2 functions as both a kinase and GTPase, and PD-linked mutations are known to influence both enzymatic acti ...

Flexible Disaster Response of Tomorrow: Final Presentation and Evaluation of the CENTAURO System

Xi Chen, Fabian Maximilian Schilling

Mobile manipulation robots have great potential for roles in support of rescuers on disaster-response missions. Robots can operate in places too dangerous for humans and therefore can assist in accomplishing hazardous tasks while their human operators work ...

Nonlinear electrical conductivity through the thickness of multidirectional carbon fiber composites

Marcos Rubinstein, Xi Chen, Anastasios Vassilopoulos, Jie Li

Lightning strikes pose a serious natural threat to carbon fiber-reinforced poly- mers (CFRPs). Knowledge of the electrical current distribution is essential for modeling the interaction between CFRP with lightning. In most applications, the anisotropy of C ...

Conversion of chitin derived N-acetyl-D-glucosamine (NAG) into polyols over transition metal catalysts and hydrogen in water

Felix Daniel Bobbink, Ning Yan, Xi Chen

N-Acetyl-D-glucosamine (NAG), the monomer of the world's second most abundant biopolymer chitin, has been for the first time converted to its corresponding amide/amino substituted sugar alcohols, smaller C2-4 polyols and N-acetylmonoethanolamine (NMEA), ov ...
