Ultrahigh-Sensitive Broadband Photodetectors Based on Dielectric Shielded MoTe /Graphene/SnS p-g-n Junctions.

Adv Mater 2018 Dec 14:e1805656. Epub 2018 Dec 14.

Department of Physics, Southern University of Science and Technology, Shenzhen, 518055, China.

2D atomic sheets of transition metal dichalcogenides (TMDs) have a tremendous potential for next-generation optoelectronics since they can be stacked layer-by-layer to form van der Waals (vdW) heterostructures. This allows not only bypassing difficulties in heteroepitaxy of lattice-mismatched semiconductors of desired functionalities but also providing a scheme to design new optoelectronics that can surpass the fundamental limitations on their conventional semiconductor counterparts. Herein, a novel 2D h-BN/p-MoTe /graphene/n-SnS /h-BN p-g-n junction, fabricated by a layer-by-layer dry transfer, demonstrates high-sensitivity, broadband photodetection at room temperature.

Methods: Air pollution indices from studies covered in this review were compared to relevant guideline standards such as the World Health Organization (WHO) 24-hr guideline and the United States Environmental Protection Agency (USEPA)'s National Ambient Air Quality Standard (NAAQS) daily permissible limits for fine particles of less than 2.

A Possible Prebiotic Ancestry of Porphyrin-Type Protein Cofactors.

Orig Life Evol Biosph 2018 Dec 13. Epub 2018 Dec 13.

Department of Bioinorganic Chemistry and Chemical Evolution, Institute of Chemistry, University of Hohenheim, Garbenstr. 30, 70599, Stuttgart, Germany.

In previous experiments that simulated conditions on primordial volcanic islands, we demonstrated the abiotic formation of hydrophobic porphyrins. The present study focused on the question whether such porphyrins can be metalated by prebiotically plausible metal ion sources. We used water-insoluble octaethylporphyrin (Hoep) as a model compound.

The effect of flexible joint-like elements on the adhesive performance of nature-inspired bent mushroom-like fibers.

Beilstein J Nanotechnol 2018 19;9:2893-2905. Epub 2018 Nov 19.

Mechanical Engineering, Texas Tech University, Lubbock, TX 79409-1021, USA.

Many organisms rely on densely packed, tilted and curved fibers of various dimensions to attach to surfaces. While the high elastic modulus of these fibers enables an extremely large number of fibers per unit area, where each fiber stands freely without sticking to its neighbors, the tilt/curvature provides them with the compliance and the directional adhesion properties to attach strongly and efficiently to a surface. Recent studies have revealed that many of such organisms also feature materials with a graded elastic modulus that is tailored towards improving the contact area without sacrificing the fiber density.

Eucalypt leaf litter impairs growth and development of amphibian larvae, inhibits their antipredator responses and alters their physiology.

Conserv Physiol 2018 10;6(1):coy066. Epub 2018 Dec 10.

Ecology, Evolution and Development Group, Doñana Biological Station (CSIC), C/ Americo Vespucio 26, Sevilla, Spain.

Consequences of human actions like global warming, spread of exotic species or resource consumption are pushing species to extinction. Even species considered to be at low extinction risk often show signs of local declines. Here, we evaluate the impact of eucalypt plantations, the best-known exotic tree species worldwide and its interaction with temperature and predators on amphibian development, growth, antipredator responses and physiology.

Morphological variations of lingula and prevalence of accessory mandibular foramina in mandibles: A study.

Natl J Maxillofac Surg 2018 Jul-Dec;9(2):129-133

Department of Oral Medicine and Radiology, Career Post Graduate Institute of Dental Sciences and Hospital, Lucknow, Uttar Pradesh, India.

Introduction: The lingula is used for identifying the site for injection of local anesthetics and for excision of nerve in facial neuralgia. The relationship between lingula and lingual nerves may aid in risk associated with an impacted third molar. Due to its connection to nerve and vascular structures, the study of the lingula provides important information related to oral and maxillofacial surgical procedures, such as the sagittal split ramus osteotomy and the intraoral vertico-sagittal ramus osteotomy carried out to correct dento facial deformities.

Air pollutant particulate matter 2.5 induces dry eye syndrome in mice.

Sci Rep 2018 Dec 13;8(1):17828. Epub 2018 Dec 13.

Department of Ophthalmology, the First Affiliated Hospital of Nanchang University, Nanchang, 330006, Jiangxi Province, China.

In this study, we explored the effects of particulate matter 2.5 (PM) eye drops on the ocular surface structure and tear function in mice and established a novel animal model for dry eye research. We found that, following treatment with PM, the tear volume and, the tear film break-up time showed statistical differences at each time point (P < 0. Read More

The immunosuppressant macrolide tacrolimus activates cold-sensing TRPM8 channels.

J Neurosci 2018 Dec 13. Epub 2018 Dec 13.

Instituto de Neurociencias de Alicante, Universidad Miguel Hernández-CSIC, 03550 San Juan de Alicante, Spain

TRPM8 is a polymodal, non-selective cation channel activated by cold temperature and cooling agents that plays a critical role in the detection of environmental cold. We found that TRPM8 is a pharmacological target of tacrolimus (FK506), a macrolide immunosuppressant with several clinical uses, including the treatment of organ rejection following transplants, treatment of atopic dermatitis and dry eye disease. Tacrolimus is an inhibitor of the phosphatase calcineurin, an action shared with cyclosporine. Read More

Fatty acids characterization and oxidative stability of spray dried designer egg powder.

Lipids Health Dis 2018 Dec 13;17(1):282. Epub 2018 Dec 13.

Department of Chemistry, Faculty of Physical Sciences, Government College University, Faisalabad, Pakistan.

Background: Designer eggs (DEs) have gained positive importance in maintaining cholesterol level, triglyceride profile and protection towards cardiovascular diseases due to the presence of essential fatty acids (EFAs) such as omega-3 (or) n-3 fatty acids. However, extreme heat conditions effect the quality as well as quantity of EFAs during the production of designer egg dried powder (DEDP). Therefore, the main mandate of research was the development of DEDP and determination of spray drying conditions impact on fatty acids composition of DEDP samples. Read More
