Preventing Benzoquinone‐Based Catalyst Aggregation Enables the One‐Step Synthesis of Highly Conductive Poly(benzodifurandione) without Post‐Reaction Purification

Advanced Materials, EarlyView.
α‐Tocopherylquinone (α‐TQ), the oxidation product of α‐tocopherol (α‐TOH), catalyzes the oxidative polymerization of 3,7‐dihydrobenzo[1,2‐b:4,5‐b′]difuran‐2,6‐dione (HBFDO). The saturated aliphatic chiral side chain of α‐TQ suppresses its crystallization, enabling high‐conductivity polymer ink without needing post‐polymerization dialysis. This scalable

Vitamin D3 and calcium to prevent hip fractures in elderly women.

New England Journal of Medicine, 1992
BACKGROUND Hypovitaminosis D and a low calcium intake contribute to increased parathyroid function in elderly persons. Calcium and vitamin D supplements reduce this secondary hyperparathyroidism, but whether such supplements reduce the risk of hip ...

Vitamin D Supplementation and Prevention of Type 2 Diabetes.

New England Journal of Medicine, 2019
BACKGROUND Observational studies support an association between a low blood 25-hydroxyvitamin D level and the risk of type 2 diabetes. However, whether vitamin D supplementation lowers the risk of diabetes is unknown.

Fully Passive Electrochemical Oxygen Sensor Enabled With Organic Electrochemical Transistor

Advanced Materials Technologies, EarlyView.
A wireless oxygen sensor that operates with low power without batteries, using organic electrochemical transistors (OECTs) powered by near‐field communication (NFC) is presented. The sensor combines an oxygen‐permeable membrane and a gel electrolyte to detect oxygen in air and complex liquids, making way for sustainable sensor technologies.

Terapevtski potencial vitamina A, retinoidov in karotenoidov za preprečevanje in zdravljenje raka sečnega mehurja

Zdravniški Vestnik
Rak sečnega mehurja je v svetovnem merilu 10. najpogostejši rak z izjemno visoko ponovljivostjo. Slovenska incidenca, umrljivost in prevalenca so pri tem raku v primerjavi z drugimi evropskimi državami in svetom nadpovprečne.

Artificially Weaved Textile‐like Surface Micromachined Graphene‐Polymer Flexible Bioelectrodes

Advanced Materials Technologies, EarlyView.
This study reports on the engineering of microscale textured surfaces of SU‐8/PMMA polymer composites much like a “weft‐warp” pattern to resemble “artificially‐weaved” textiles. These microstructured surfaces enable conformal layering of functional reduced graphene oxide (rGO), all‐in‐all offering favorable features including remarkable self ...

Effects of stocking density on the performance of lettuce (Lactuca sativa) in small‐scale lettuce‐Nile tilapia (Oreochromis niloticus L.) aquaponic system

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 458-469, December 2022., 2022
Graphical Abstract : Aquaponics, hydroponics, stocking density. Abstract Aquaponics incorporates aquaculture with hydroponics, whose principles and operations largely remain untested. Currently, there is a knowledge gap on the performance of aquaponic systems used for fish production under different stocking densities.
