Article Synopsis
- A study aimed to evaluate the fracture resistance of dental ceramics by comparing a custom load-to-fracture test with a conventional method for measuring fracture strength.
- Acoustic emission testing was used to assess fracture toughness in three types of dental materials (glass sheets, zirconia sheets, and monolithic zirconia crowns), with a total of 130 samples tested.
- Results indicated that the custom method produced lower mean fracture loads for all sample types compared to conventional testing, suggesting it may better detect cracks at lower loads, although more research is needed for broader applicability and accuracy.
Kinetic Exploration of Nanoscale Polymorphs through Interface Energy Adjustment.
ACS Nano
August 2024
Department of Chemistry, The University of Tokyo, 7-3-1 Hongo, Bunkyo-ku, Tokyo 113-0033, Japan.
Traditionally, the study of crystal polymorphism has relied on thermodynamics and measurements averaged over time and the crystal's constituents. This work introduces a kinetic approach to phase identification─millisecond cinematographic electron microscopic imaging of the dynamics of phase transitions of crystals of a few nm in diameter. We demonstrate a remarkable impact of the interface energy on the relative stability of the nanocrystal's polymorphs, enabling in situ manipulation of phase transitions through size increase or decrease.

A body of experimental research has aimed to investigate processes underlying dream formation by examining the effects of a range of pre-sleep stimuli and events on subsequent dream content. Given its ever-growing presence and salience in people's everyday lives, pre-sleep media consumption stands out as a key variable that could influence people's dreams. We conducted a scoping review to evaluate the experimental evidence of the effects of pre-sleep exposure to visual media on dream content.

Background: Physiological motion of the lumbar spine is a topic of interest for musculoskeletal health care professionals since abnormal motion is believed to be related to lumbar complaints. Many researchers have described ranges of motion for the lumbar spine, but only few have mentioned specific motion patterns of each individual segment during flexion and extension, mostly comprising the sequence of segmental initiation in sagittal rotation. However, an adequate definition of physiological motion is still lacking.

This article examines cinematographic observational studies of infants conducted by a loosely connected group of female psychologists and physicians in the USA from the 1930s to the 1960s. Largely forgotten today, these practitioners realized detailed and carefully planned research projects about infant behavior in a variety of settings-from the laboratory to the well-baby clinic. Although their studies were in conversation with better-known works, such as John Bowlby's research on attachment and René Spitz's films on institutionalized infants, they differed in a close examination of individual characteristics of babies and a critical attitude toward contemporary notions of 'pathological mothering'.
