Hydrogen Bonding Strength Determines Water Diffusivity in Polymer Ionogels.

J Phys Chem B 2021 May 12. Epub 2021 May 12.

Department of Chemical Engineering, University of California Santa Barbara, Santa Barbara 93106-9010, United States.

Polymeric ionogels, cross-linked gels swollen by ionic liquids (ILs), are useful vehicles for the release and storage of molecular solutes in separation, delivery, and other applications. Although rapid solute diffusion is often critical for performance, it remains challenging to predict diffusivities across multidimensional composition spaces. Recently, we showed that water (a neutral solute) diffuses through alkyl-methylimidazolium halide ILs by hopping between hydrogen bonding sites on relatively immobile cations. Read More

Fabry-Perot cavity enhanced three-photon luminescence of atomically thin platinum diselenide.

Nanoscale 2021 May 11. Epub 2021 May 11.

Institute of Photonic Chips, University of Shanghai for Science and Technology, Shanghai 200093, China and Centre for Artificial-Intelligence Nanophotonics, School of Optical-Electrical and Computer Engineering, University of Shanghai for Science and Technology, Shanghai 200093, China.

Two-dimensional materials, such as transition metal dichalcogenides (TMDs), exhibit intriguing physical properties that lead to both fundamental research and technology development. The recently emerged platinum diselenide (PtSe2), as a new member of the TMDs, has attracted increasing attention because of its good air stability, large refractive index and high electron mobility. However, being atomically thin significantly hinders its interaction with light, severely limiting the spontaneous or stimulated linear and nonlinear emission. Read More

High-Performance Full-Photolithographic Top-Contact Conformable Organic Transistors for Soft Electronics.

Adv Sci (Weinh) 2021 May 18;8(9):2004050. Epub 2021 Feb 18.

Center for Advanced Optoelectronic Functional Materials Research and Key Lab of UV-Emitting Materials and Technology of Ministry of Education Northeast Normal University 5268 Renmin Street Changchun 130024 China.

Organic thin-film transistors (OTFTs) are identified to be the most promising candidate for next-generation wearable and implantable electronics because of their unique advantages including their flexibility, low cost, long-term biocompatibility, and simple packaging. However, commercialization of organic transistors remains an enormous challenge due to their low mobility and lack of scalable strategy for high-precise soft devices. Here, a novel photolithography fabrication strategy is proposed, which is completely compatible with various commercial organic semiconductor materials, for the first demonstration of the fully photolithographic top-contact conformable OTFTs with the device density as high as 1523 transistors cm.

HBD1 protein with a tandem repeat of two HMG-box domains is a DNA clip to organize chloroplast nucleoids in .

Proc Natl Acad Sci U S A 2021 May;118(20)

Department of Botany, Graduate School of Science, Kyoto University, Kita-Shirakawa Oiwake-cho, Sakyo-ku, Kyoto 606-8502, Japan;

Compaction of bulky DNA is a universal issue for all DNA-based life forms. Chloroplast nucleoids (chloroplast DNA-protein complexes) are critical for chloroplast DNA maintenance and transcription, thereby supporting photosynthesis, but their detailed structure remains enigmatic. Our proteomic analysis of chloroplast nucleoids of the green alga identified a protein (HBD1) with a tandem repeat of two DNA-binding high mobility group box (HMG-box) domains, which is structurally similar to major mitochondrial nucleoid proteins transcription factor A, mitochondrial (TFAM), and ARS binding factor 2 protein (Abf2p).

Alligators employ intermetatarsal reconfiguration to modulate plantigrade ground contact.

J Exp Biol 2021 May 11. Epub 2021 May 11.

Department of Ecology and Evolutionary Biology, Division of Biology and Medicine, Brown University, Providence, RI, USA.

Feet must mediate substrate interactions across an animal's entire range of limb poses used in life. Metatarsals, the 'bones of the sole,' are the dominant pedal skeletal elements for most tetrapods. In plantigrade species that walk on the entirety of their sole, such as living crocodylians, intermetatarsal mobility offers the potential for a continuum of reconfiguration within the foot itself.

The End of the Partnership With a Guide Dog: Emotional Responses, Effects on Quality of Life and Relationships With Subsequent Dogs.

Front Vet Sci 2021 22;8:543463. Epub 2021 Apr 22.

Institute of Veterinary, Animal and Biomedical Sciences, Massey University, Palmerston North, New Zealand.

Guide dogs are mobility aids that facilitate independent travel of people who are blind or visually impaired. Additional benefits imparted to the guide dog handler include companionship, and increased: social-function, self-esteem and confidence. Some evidence shows that the end of the guide dog partnership can result in reduced mobility, and may have profound psychosocial effects on the handler due to feelings of bereavement and loss of self-esteem.

Revealing the dynamic adsorption and diffusion of peptide amphiphile on supported lipid bilayer by single molecule experiment and simulation.

Colloids Surf B Biointerfaces 2021 May 1;204:111809. Epub 2021 May 1.

Key Laboratory of Materials Chemistry for Energy Conversion and Storage (HUST) of Ministry of Education, School of Chemistry and Chemical Engineering, Huazhong University of Science and Technology (HUST), Wuhan, 430074, China.

Evaluation of four field portable devices for the rapid detection of mitragynine in suspected kratom products.

J Pharm Biomed Anal 2021 Apr 30;201:114104. Epub 2021 Apr 30.

U.S. Food and Drug Administration, Forensic Chemistry Center, 6751 Steger Drive, Cincinnati, OH, 45237, USA. Electronic address:

The development of a method for the rapid screening of food and drug products for constituents such as mitragynine, the most abundant alkaloid found in Mitragyna speciosa (kratom) plant leaves, has become increasingly important. The use of kratom is said to produce stimulant or narcotic effects and poses risks of addiction, abuse, and dependence, much like other opioids. Direct Analysis in Real Time with thermal desorption mass spectrometry (DART-TD-MS), hand-held mass spectrometry, portable ion mobility spectrometry (IMS), and portable Fourier-transform infrared spectroscopy (FT-IR) were each evaluated as field-deployable screening techniques for the detection of mitragynine in food and drug products.

Hydrothermally-altered feldspar as an environmentally-friendly technology to promote heavy metals immobilization: Batch studies and application in smelting-affected soils.

J Environ Manage 2021 May 5;291:112711. Epub 2021 May 5.

School of Agricultural Sciences, Department of Soil Science, Federal University of Lavras, Lavras, MG, Brazil. Electronic address:

Hydrothermally-altered feldspar (HydroPotash, HYP) possesses, among other physicochemical properties, high pH buffering and cation exchange capacity. Therefore, it may potentially remove heavy metals from aqueous solutions and immobilize these metals in contaminated soil. This study aimed to evaluate the capabilities of two types of HydroPotash (HYP-1 and HYP-2) and a zeolite sample (a commercial adsorbent) for immobilizing cadmium (Cd), zinc (Zn), and lead (Pb) from both aqueous solution and contaminated soils from a Zn-smelting area (classified as soil, soil, and soil based on their level of soluble metal concentration).
