Cleaning ability of rotary NiTi systems with different kinematics

Bulletin of the National Research Centre, 2019
Background The aim of this study was to compare the cleaning ability of rotary NiTi systems with different kinematics: ProTaper Next (PTN) (continuous rotation motion), WaveOne Gold (WOG) (reciprocating motion), and Twisted File Adaptive (TFA) (adaptive ...

Cheetah Experimental Platform Web 1.0: Cleaning Pupillary Data [PDF]

, 2017
Recently, researchers started using cognitive load in various settings, e.g., educational psychology, cognitive load theory, or human-computer interaction. Cognitive load characterizes a tasks' demand on the limited information processing capacity of the

Repetition, pattern and the domestic: notes on the relationship between pattern and home-making [PDF]

, 2010
Repetition constitutes the very essence of pattern. Repetition is also the basis of our most ordinary actions. Repetitive gestures are usually so integrated in our lives that we tend to take them for granted.

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

Advanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Technical note: formation of airborne ice crystals in a wall independent reactor (WIR) under atmospheric conditions [PDF]

, 2008
Both, gas and particle scavenging contribute to the transport of organic compounds by ice crystals in the troposphere. To simulate these processes an experimental setup was developed to form airborne ice crystals under atmospheric conditions. Experiments

Ferrocene Derivatives Enable Ultrasensitive Perovskite Photodetectors with Enhanced Reverse Bias Stability

Advanced Functional Materials, EarlyView.
Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

Advanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...
