Thermally efficient compact fluorescent fixtures [PDF]

open access: yesConference Record of the 1990 IEEE Industry Applications Society Annual Meeting, 2002
A series of prototype fixtures that employ convective venting and heat sinking to reduce elevated lamp temperatures is described. Experimental data show that decreases in fixture efficiency can approach 20% due to elevated temperature conditions inside the lamp compartment.

Stochastic efficiency for effusion as a thermal engine [PDF]

open access: yesEPL (Europhysics Letters), 2015
The stochastic efficiency of effusion as a thermal engine is investigated within the framework of stochastic thermodynamics. Explicit results are obtained for the probability distribution of the efficiency both at finite times and in the asymptotic regime of large deviations.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
