Mechanisms for accumulation and migration of technetium-99 in saltmarsh sediments

open access: yes, 2000
This thesis describes the development of analytical methods for both the bulk determination of 99Tc, and determination of 99Tc in sequential extracts from sediments.

The Effect of Iron Deficiency Anemia on the Morphology–Voltage–P Wave Duration (MVP) Risk Score

open access: yesAnnals of Noninvasive Electrocardiology
Background Iron deficiency anemia (IDA) is a common global health issue affecting over two billion people and is associated with cardiovascular complications. Electrocardiographic (ECG) abnormalities may reflect cardiac involvement in IDA. The Morphology‐

Endogenous tetrahydrobiopterin in humans: circadian rhythm, sex, race, age, and disease status

open access: yesFrontiers in Pharmacology
Introduction6R-L-erythro-5,6,7,8-tetrahydrobiopterin (BH4) is an essential cofactor for multiple enzymes, including phenylalanine hydroxylase (PAH). Exogenous BH4, or its natural precursor sepiapterin, is utilized to treat patients with phenylketonuria ...

Semiconducting Polymers Post‐Functionalized With Ureido‐Pyrimidinone for Robust Stretchable Transistors

open access: yesAdvanced Functional Materials, EarlyView.
The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable

Synthesis and Biochemical Characterization of Tricyclothymidine Triphosphate (tc-TTP) [PDF]

open access: yes, 2014
Tricyclo-DNA (tc-DNA) is a conformationally restricted oligonucleotide analogue that exhibits promising properties as a robust antisense agent. Here we report on the synthesis and biochemical characterization of tc-TTP, the triphosphate of a tc-DNA ...

Nanoscale Spatial Tuning of Superconductivity in Cuprate Thin Films via Direct Laser Writing

open access: yesAdvanced Functional Materials, EarlyView.
Maskless direct laser writing enables local control of oxygen stoichiometry in epitaxial YBCO thin films under ambient conditions. Sub‐micrometer grayscale patterns with tunable optical response and superconducting transport properties are achieved.

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

open access: yesAdvanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...
