colorless plate crystal (0.028 × 0.034 × 0.046 mm3) of 2 for single crystal data analysis. All the data were collected using a Bruker SMART BREEZE diffractometer equipped with a 1K CCD area detector using graphite monochromated Mo Kα radiation at 200 K. A hemisphere of data was collected using a narrow-frame method with the scan widths of 0.30° in omega and an exposure time of 5 s/frame. The first 50 frames were remeasured at the end of the data collection to monitor the instrument and crystal stability

R L Timings describes materials as being a vital part of the evolution of mankind. He stated that our ability to use and develop materials to satisfy a human requirement is what really set us apart from other animals. This started from building weapons by manipulating stone and wood to hunt and defend territory. He goes on to say this lead to building tools to cultivate land and to manufacture artefacts such as cooking utensils. He finishes this part of his writing by listing how materials have developed

Calcium- Phosphate Ceramics (CPC) Calcium phosphate ceramics are a type of ceramics with varying calcium-to-phosphate ratio, the important properties of calcium phosphate biomaterials are their bioresorption and bioactivity. The most widely used calcium phosphate based bioceramics are hydroxyapatite (HAP) and β-tricalcium phosphate (β-TCP). Synthetic Hydroxyapatite (HA) is a calcium phosphate whose stoichiometric formula corresponds to Ca10(PO4)6(OH)2 with calcium-to-phosphate ratio is 1.67, it

Bryn slid into the chair opposite Tony, slapping his hand on the table. He nodded briefly to the waitress as he settled in. Tony eyed the data crystal with mixed feelings. “That’s everything I could find on Fancher and his crew,” Bryn said without equivocation. “Pretty standard stuff; Fancher is career Fleet. Commanding officer of the Rankori for 6 years, service record reads like a Fleet novel.” Bryn sipped the coffee the waitress placed in front of him, grimacing at it before adding copious

exploring the use of these single metal oxides in a mixed form. The three dimensional or geometrical arrangement of molecules or atoms as points in a specific form in space is called a crystal lattice. The smallest unit of a crystal lattice is called a unit cell. A unit cell is the smallest repeating unit of a crystal. The unit cells have different structures. These arrangements are also called Bravais

brought to the earth’s surface in Xenolith, from the earth’s mantle, as a result of volcanic eruptions. Asteroid and meteorite sites also often result in high temperatures and pressures, which release stardust and debris, often including diamond crystals. NASA scientists have found many nanodiamonds in meteorites within our

Effect of processing technique and core thickness on fracture resistance of Lithium disilicate copings having two different thicknesses Keywords: IPS e.max;Press; CAD / CAM; core thickness; fracture strength. Introduction High-strength All ceramic restorations, with different composition, structure, and processing methods, have been introduced as an alternative to metal ceramic restorations in many applications (1). Due to their translucency and strength, IPS e.max ceramics

INTRODUCTION A successful orthopedic implant must meet following criteria: it resembles natural bone, is anti-inflammatory, biocompatible, bearable, has a long lifetime, and supports cell proliferation.1 Since titanium alloy satisfies most of these conditions, it has been widely used as a main element of current implants.2 Another benefit of Ti is the oxide layer yielded from environmental effects, which works as a protective cover against severe situations.1,2 Yet not all the requirements of

Crystal Structures and Additive Manufacturing Report Introduction Crystal structures refers to the certain ordered pattern of stacking atoms, and it can repeat and stack to form the material (Wikipedia, Crystal structure). We are studying how atoms are arranged within a unit cell. It is crucial that different crystal structure can determine the properties of materials. By analyzing the crystal structure, we can create the materials with certain properties. The additive manufacturing, also called
