Nota sôbre a dosagem iodométrica da vitamina C nos frutos cítricos Iodometric determination of vitamin C in citrus fruit juices

open access: yesMemorias do Instituto Oswaldo Cruz, 1943
Ascorbic acid was determined in pure aquous solutions and in citrus fruit juices by iodometric, dichlorophenolindophenol and iodate methods. More constant values were obtained with iodate and Tillmans methods.

Autocatalytic plume pinch-off

open access: yes, 2010
A localized source of buoyancy flux in a non-reactive fluid medium creates a plume. The flux can be provided by either heat, a compositional difference between the fluid comprising the plume and its surroundings, or a combination of both.

f‐Block Element‐Based MOF Thin Films: A Platform for Luminescence, Sensing, and Energy Applications

open access: yesSmall, EarlyView.
f‐Block element–based metal–organic framework (f‐MOF) thin films offer exceptional potential for luminescent, sensing, and energy‐related applications. This review surveys recent progress in their synthesis, characterization, and functional implementation, emphasizing the diversity of available thin‐film fabrication strategies. The convergence of these

Iodate in calcite, aragonite and vaterite CaCO3: Insights from first-principles calculations and implications for the I/Ca geochemical proxy [PDF]

open access: yes, 2018
The incorporation of iodine into each of the three polymorphs of CaCO3 – calcite, aragonite and vaterite, is compared using first-principles computational simulation.

A flexible arched artificial photoreceptor constructed by photodeformable liquid crystal polymers and its application in vision restoration

open access: yesSmart Molecules, EarlyView.
A flexible arched artificial photoreceptor with high stability and biocompatibility was fabricated by integrating liquid crystal polymers with polyvinylidene fluoride‐trifluoroethylene. This device exhibits robust photoelectric responses under low‐intensity illumination and demonstrates efficacy in restoring visual responses in blind rats following ...

Modeling iodide ? iodate speciation in atmospheric aerosol

open access: yes, 2006
International audienceThe speciation of iodine in atmospheric aerosol is currently poorly understood. Models predict negligible iodide concentrations and accumulation of iodate in aerosol, both of which is not confirmed by recent measurements. We present

Sodium channel inactivation kinetics of rat sensory and motor nerve fibres and their modulation by glutathione [PDF]

open access: yes, 1993
Na+ channel currents of rat motor and sensory nerve fibres were studied with the patch-clamp technique on enzymatically demyelinated axons. Differences between motor and sensory fibres in multi-channel inactivation kinetics and the gating of late single ...

First attempt at using a synthetic diet in short‐lived killifish, a vertebrate model of ageing

open access: yesJournal of Fish Biology, EarlyView.
Abstract Diet standardization of model organisms is crucial for experimental consistency and repeatability in laboratory research, yet laboratory fish often lack species‐specific, open‐formula standardized diets. This study aims to address this gap by testing the effect of macronutrient content on the performance of Nothobranchius furzeri, an ...

Effect of Two Therapeutic Renal Diets on Hormonal and Regulatory Pathways Affecting Calcium Homeostasis in Cats With Early‐Stage Chronic Kidney Disease

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Chronic kidney disease (CKD) is a known risk factor for hypercalcemia in cats. Phosphate‐restricted diets have also been implicated in causing hypercalcemia, in part because phosphate restriction increases the Ca:P ratio. The primary objective of this study was to evaluate the impact of two different therapeutic renal foods on ionized (iCa ...

Selective capture of iodate anions by a cerium-based metal-organic framework

open access: yesNational Science Open
Effective remediation of radioactive IO3− is highly desirable for fuel reprocessing, medical waste disposal, and nuclear accidents. However, the nature of high solubility, strong mobility, and extremely hard to bind with minerals for IO3− makes this task
