Synthesis and viscosity behavior of poly(γ-p-biphenylmethyl-L-glutamate) in benzene/dichloroacetic acid mixtures, a comparison with poly(γ-benzyl-L-glutamate) [PDF]

open access: yes, 1974
The synthesis of poly(γ-p-biphenylmethyl-L-glutamate), PBPLG, (poly{L-imino-1-[2-(4-biphenylylmethoxycarbonyl)ethyl]-2-oxoethylene}), (1d) is described. The viscosity behavior of this polymer in benzene/dichloroacetic acid mixtures (c=0,2.10 -3 - 1,4.10 -

Cupriavidus metallidurans CH34 Possesses Aromatic Catabolic Versatility and Degrades Benzene in the Presence of Mercury and Cadmium

open access: yesMicroorganisms, 2022
Heavy metal co-contamination in crude oil-polluted environments may inhibit microbial bioremediation of hydrocarbons. The model heavy metal-resistant bacterium Cupriavidus metallidurans CH34 possesses cadmium and mercury resistance, as well as genes ...

Electronic spectra of polyatomic molecules with resolved individual rotational transitions [PDF]

open access: yes, 1981
The density of rotational transitions for a polyatomic molecule is so large that in general many such transitions are hidden under the Doppler profile, this being a fundamental limit of conventional high resolution electronic spectroscopy.

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.

Benzene formation in the inner regions of protostellar disks [PDF]

open access: yes, 2006
Benzene (c-C6H6) formation in the inner 3 AU of a protostellar disk can be efficient, resulting in high abundances of benzene in the midplane region. The formation mechanism is different to that found in interstellar clouds and in protoplanetary nebulae,

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Benzene [PDF]

open access: yesACM Transactions on Architecture and Code Optimization, 2018
This article proposes Benzene, an energy-efficient distributed SRAM/STT-RAM hybrid cache for manycore systems running multiple applications. It is based on the observation that a naïve application of hybrid cache techniques to distributed caches in a manycore architecture suffers from limited energy reduction due to uneven utilization of scarce SRAM ...

Simulation of benzene transport and biodegradation during transient hydraulic conditions [PDF]

open access: yes, 2000
Thesis (M.S.) University of Alaska Fairbanks, 2000MODFLOW and BIOMOC were used to simulate transport and biodegradation of benzene in the alluvial aquifer adjacent to the Chena River. MODFLOW was used to calculate ground water fluxes at the boundaries of
