Comparison of lithium disilicate blocks and resin blocks for CAD-CAM
Published:05 August 2023Odontology
(2023)AbstractA
total of 20 lithium disilicate glass –ceramics (IPS e.max CAD, Ivoclar
Vivadent) and 20 resin nano-ceramic (Voco Grandio Blocks) onlay
restorations were performed in 20 patients using a split-mouth design to
compare the two-year clinical performance of lithium disilicate and
resin nano-ceramic onlay restorations. Both restoration s were evaluated
at baseline, one-year, and two-year clinical follow-ups based on the
modified United States Public Health Service (USPHS) criteria.
Chi-square and Fisher’s exact tests showed no statistically signific...

‘I’m not littering – the Nanofiche is very small!’: meet the man who sends art to the moon
Physicist Samuel Peralta ’s Lunar Codex project has seen the work of 30,000 artists from 158 countries carried on into space – and the effect on them has been profoundBefore the age of space exploration, all artists could do was look up and gaze, sketch and write about a moon they could never reach. But Samuel Peralta, a semi-retired physicist living in Canada, has changed all that with the launch of theLunar Codex, a project that sends art to the moon, converted into Nanofiche files (think microfiche but smaller) and left on the surface in time capsules.“The whole thing started with the realisation that Nasa was goi...

This butterfly-inspired paint could keep your car cool
Scientists have designed a thin film that mimics a butterfly’s wings to help keep surfaces cool. The vivid blue color of morpho butterflies doesn’t come from pigment but from tiny nanostructures on their wings that bend and reflect light. In a recent study, scientists designed a thin film with a…#readfullstory (Source: Reuters: Health)

Evaluation of the antibacterial activity of dental adhesive containing biogenic silver nanoparticles decorated nanographene oxide nanocomposites (Ag@nGO NCs) and effect on bond strength to dentine
Published:12 July 2023Odontology
(2023)Cite this articleAbstractOur
study aimed to evaluate the antibacterial activities and dentin bond
strengths of silver nanoparticles (Ag NPs) and silver nano-graphene
oxide nanocomposites (Ag@nGO NCs) produced by green and chemical
synthesis methods added to the dental adhesive. Ag NPs were produced by
green synthesis (biogenic) (B-Ag NPs) and chemical synthesis methods
(C –Ag NPs) and deposited on nGO (nano-graphene oxide). Ag NPs and Ag@nGO
NCs (0.05% w/w) were added to the primer and bond (Clearfil SE Bond).

‘Endless possibilities’: the chemists changing molecules atom by atom
A new method called ‘skeletal editing’ offers a hugely simplified way to alter matter, paving the way for world-changing innovations in personalised medicine and sustainable plasticsAsk Mark Levin what excites him about his work, and the associate professor of chemistry at the University of Chicago could double as a poet. “We’re one of the only fields of science that at its core is about making things that have never existed anywhere else in the universe, and would never have existed if we didn’t intervene,” he enthuses. “We get to manipulate matter at the atomic level to shape it to whatever purpose we can t...

Electrified cement could turn houses and roads into nearly limitless batteries
Tesla’s Powerwall, a boxy, wall-mounted, lithium-ion battery, can power your home for half a day or so. But what if your home
was
the battery?
Researchers have come up with a new way to store electricity in cement, using cheap and abundant materials. If scaled up, the cement could hold enough energy in a home’s concrete foundation to fulfill its daily power needs. Scaled up further, electrified roadways could power electric cars as they drive. And if scientists can find a way to do this all cheaply the advance might offer a nearly limitless capacity for storing energy from intermittent renewable sources...

AI helps crack salt water ’s curious electrical properties
Water is a near-universal solvent, able to dissolve substances ranging from limestone to the sugar in your coffee. That chemical superpower originates, oddly enough, in water’s electrical properties. It can oppose and almost entirely cancel electric fields—including attractions among dissolved ions that might otherwise pull them together. Curiously, dissolving salt in water weakens that electrical response. Now, a team of physicists has figured out exactly why this happens, using state-of-the-art computer simulations bolstered by artificial intelligence (AI).
“This is a fundamental property of water and one can...
