Abstract Composites‐based photocatalysis relies on the interfacial electron transfer between metallic cocatalyst and photosensitizer (the semiconductor) to realize spatial separation of charge carriers. Herein, an ingenious heterojunction Co‐CN single atom catalysts (SACs) g‐C 3 N 4 is constructed for heterogeneous photo‐Fenton‐like reactions. Driven by built‐in electric field across heterojunc...

BACKGROUND Mutations in SACS, leading to autosomal-recessive spastic ataxia of Charlevoix-Saguenay (ARSACS), have been identified as a frequent cause of recessive early-onset ataxia around the world. Here we aimed to enlarge the spectrum of SACS mutations outside Quebec, to establish the pathogenicity of novel variants, and to expand the clinical and imaging phenotype. METHODS Sequencing of S...

Recently Stebbins and Eakin (1) revived in modified form a concept of a photothermal function of the parietal eye of reptiles. Laboratory and field studies indicated that surgical removal of the "eye" from the lizard, Sceloporus occidentalis, leads to increased activity and exposure to light. They postulated that under stimulation the retina of the "eye" produces a hormone which, perhaps after ...

Chlorophyll and carotenoid are the main pigments that responsible for coloration of citrus fruit. The changes in their contents related to development stage During fruit maturation, carotenoids massively accumulated flavedo juice sacs, while chlorophyll decreased rapidly. In contrast, increase content decrease observed during regreening process. addition, plant hormones environmental conditions...

Energy is the substance foundation of human society. Single−atom catalysts (SACs) have emerged as promising electrode materials in energy field owing to their unique characteristics. It was demonstrated that hydrogen evolution reaction (HER) performance SACs relies on metal−centric species and corresponding local coordination engineering. Herein, recent progress relating asymmetric atomic for H...

Ultrasound has revolutioned the care of women carring twins. First trimester evaluation is the best time to determine chorioniocity and amnioniocity in multiple gestations. First trimester diagnosis is based on the number of gestational sacs, amnions and yolk sacs. Growth rate in multiple multiple gestations during the fist and early second trimesters parallels the growth rate of singleton preg...

Converting CO2 emissions to valuable carbonaceous chemicals/fuels under mild conditions provides a sustainable way maintain carbon balance and alleviate the energy shortage. Low-dimensional material (LDM) supported single-atom catalysts (SACs) have been attracted significant attention for electrochemical reduction reaction (ECR) in recent years. This is mainly because integrating single-atoms L...
