郭新闻论文成果：Defect-Enriched N,O-Codoped Nanodiamond/Carbon Nanotube Catalysts for Styrene Production via Dehydrogenation of Ethylbenzene
nanodiamond/carbon nanotube hybrid nitrogen and oxygen codoping structural defect direct dehydrogenation styrene production
2023/3/6
Owing to the unique structure and enriched surface ketonic carbonyl group, nanodiamond (ND) shows excellent catalytic performance for dehydrogenation reaction. However, the agglomeration of predispers...
Study reports repair of mitochondrial recycling defect linked to Parkinson’s disease
dopamine PD mitochondria recovery
2021/8/11
A study in mice shows that an experimental small molecule helped restore the removal of damaged mitochondria from dopamine-producing brain cells.
Sometimes 3D printers mess up. They extrude too much material, or too little, or deposit material in the wrong spot. But what if this bug could be turned into a (fashionable) feature?
DEEP LEARNING AND IMAGE PROCESSING FOR AUTOMATED CRACK DETECTION AND DEFECT MEASUREMENT IN UNDERGROUND STRUCTURES
Deep Learning Automated Crack Detection Photographic Tunnelling Surveys
2018/6/4
This work presents the combination of Deep-Learning (DL) and image processing to produce an automated cracks recognition and defect measurement tool for civil structures. The authors focus on tunnel c...
Coming to a monitor near you:a defect-free,molecule-thick film
defect-free molecule-thick film
2015/12/7
An emerging class of atomically thin materials known as monolayer semiconductors has generated a great deal of buzz in the world of materials science. Monolayers hold promise in the development of tra...
Robust registration of defect set by local consistency of point data
Registration defect inspection robustness consistency
2015/8/25
A novel registration algorithm using Local consistency of point dispersion (LCPD) is proposed, which is based on a new type of measure of consistency between two sets of point data. It is expected to ...
Biomechanical assessment of freeze-dried allograft cortical bone plate graft in canine bone defect model
bone defect model dual-energy x-ray absorptiometry absorbable bone plate
2015/4/2
Freeze-dried cortical bone can be used as a biological plate, either alone or in combination with other internal fixation devices, to stabilize fractures. In addition to it conferring mechanical stabi...
Scattering of a Solitary Pulse on a Local Defect or Breather
Model of nonlinear impulsive nonlinear defect optical pulse long fiber nonlinear optical fiber
2014/12/29
A model is introduced to describe guided propagation of a linear or nonlinear pulse which encounters a localized nonlinear defect, that may be either static or breather-like one. The model with the st...
Restriction of A-discriminants and dual defect toric varieties
Variable characterization Gail double double defect classification
2014/12/25
We study the A-discriminant of toric varieties. We reduce its computation to the case of irreducible configurations and describe its behavior under specialization of some of the variables to zero. We ...
Assessing climate model software quality: a defect density analysis of three models
model software quality: three models
2014/12/10
A climate model is an executable theory of the climate; the model encapsulates climatological theories in software so that they can be simulated and their implications investigated. Thus, in order to ...
Pig Spermatozoa Defect in Acrosome Formation Caused Poor Motion Parameters and Fertilization Failure through Artificial Insemination and In vitro Fertilization
Boar Sperm Motion Parameters In vitro Fertilization Acrosome Defect
2016/5/17
The selection of morphologically normal spermatozoa is critical to obtain high breeding performances in boar breeding farms and artificial insemination (AI) centers. Parameters for the selection of se...
Tunable Reflection Bands and Defect Modes in One-Dimensional Tilted Photonic Crystal Structure
Photonic Crystal Structure Photonic Band Gap (PBG) Omnidirectional Reflector Tilted PC Structure De-fect Modes
2013/1/30
We show theoretically that range of reflection bands and defect modes inside the band gap can be tuned by using a one-dimensional tilted photonic crystal (TPC) structure. A TPC structure is similar to...
