Ultra-Dense Nano- and Molecular-Electronic Circuits [PDF]

, 2007
This thesis describes research towards the realization of large-scale, ultra-dense nanowire-based circuits. The primary means for the construction of such circuits is the superlattice nanowire pattern transfer (SNAP) technique.

Ultra-Low-Density Carbon Nanotube Aerogel Film for Fast and Sensitive Bolometric Sensing

, 2023
In various applications, infrared (IR) detectors with quick responses and high sensitivity at room temperature are essential. This work synthesizes carbon nanotube aerogel films (CAFs) with an ultra-low density of 1.33 mg cm–3.

Quadratic behavior of fiber Bragg grating temperature coefficients [PDF]

, 2004
We describe the characterization of the temperature and strain responses of fiber Bragg grating sensors by use of an interferometric interrogation technique to provide an absolute measurement of the grating wavelength. The fiber Bragg grating temperature

ULT freezer performance and dual-temperature storage in a modern biobank: preserving sample integrity during transition

Journal of Laboratory Medicine
This study evaluated temperature stability, warm-up characteristics, and energy consumption of ultra-low temperature (ULT) freezers operated at −80 °C, −70 °C, and −60 °C, to support sustainable storage practices in biobanking.

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Balancing Sustainability and Specimen Protection [version 2; peer review: 1 approved, 2 approved with reservations, 1 not approved]

F1000Research
Background Biobanks are critical infrastructures for biomedical research but are energy- and cost-intensive due to reliance on ultra-low temperature (ULT) storage and redundant systems.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.
