Are diamonds GaN’s best friend? Revolutionizing transistor technology
The integration of a 3C-SiC layer between GaN and diamond significantly reduces thermal resistance at the interface and improves heat dissipation, allowing for better performance. Credit: Jianbo Liang, Osaka Metropolitan University Researchers at Osaka Metropolitan University are proving that diamonds are so much more than just a girl’s best friend. Their groundbreaking research focuses on…

Using molecular ‘cookie cutters’ to view membrane protein organization
With Native-nanoBleach, nanodiscs containing target membrane proteins and their native cell membrane environment are cut out of the cell membrane. Each protein subunit has a molecule attached to it that fluoresces under light. Over time, the light exposure will bleach the fluorescent molecules, and the step-wise decrease in fluorescence allows researchers to count how many…

Magnetic order in 2D antiferromagnets revealed by spontaneous anisotropic magnetostriction
First principles analysis of spontaneous magnetostriction in MPS3 Transition-metal phosphorus trisulphides, with general formula MPS3, are layered materials stacked in a monoclinic lattice with symmetry group C2/m17, as shown in the top view of a single-layer in the paramagnetic phase, Fig. 1a, top panel. The spins of FePS3 point out-of-plane, whereas both CoPS3 and NiPS3 are…

Molecular motion cools off gold nanoclusters
Competing interests Rice University has patented molecular motor-based technologies for cancer treatment. These technologies have been licensed to a company in which J.M.T. is a shareholder, but he is not an officer, director or employee. Conflicts of interest are mitigated though regular disclosure to and compliance with the Rice University Office of Sponsored Programs and…

Polar bear fur-inspired sweater is thinner than a down jacket — and just as warm
Chinese scientists have created a sweater as snuggly as this bear, using synthetic fibres.Credit: Belfalah Soufian/500px via Getty A sweater knitted from a fibre that mimics polar bear fur offers as much warmth as a down jacket, despite being one-fifth as thick, according to a study published today in Science1. The fibre — made from…

Redox-enabled electronic interrogation and feedback control of hierarchical and networked biological systems
Chemicals Potassium chloride (KCl), H2O2 (30%), phosphate-buffered saline (PBS), potassium phosphate monobasic (KH2PO4), potassium phosphate dibasic (K2HPO4), potassium hexachloroiridate(III) (K3IrCl6, Ir), and gelatin from porcine skin (gel strength ≈ 175 g Bloom, Type A, G2625) were purchased from Millipore-Sigma. All antibiotics (ampicillin, kanamycin, and chloramphenicol) were purchased from Millipore-Sigma. Lysogeny broth (LB) and agarose were from Fisher Scientific.…

A dual-mode fiber-shaped flexible capacitive strain sensor fabricated by direct ink writing technology for wearable and implantable health monitoring applications
Fabrication and characterization of the FSFCSS As shown in Fig. 1a, b, FSFCSS presents a three-layer structure, namely, the elastic TPU fiber, parallel helical Ag electrodes, and BTO@Ecoflex encapsulation layer. The TPU fiber was selected as the substrate material due to its excellent elasticity (over 400%) and high rebound rate (>95%). A parallel helical structure…

A decouple-decomposition noise analysis model for closed-loop mode-localized tilt sensors
Device structure and characterization The mechanical configuration of the mode-localized tilt sensor comprises a proof mass supported by four suspensions, a pair of differential microlever force amplifiers, two identical clamped-clamped (C–C) resonators connected by a mechanical microlever coupling structure, and a virtual electrostatic tuning structure, as shown in Fig. 1a, b25,26. The dimensions of the…

Study details how biomimetic nanomaterials can minimize damage after a heart attack
Effect of controlled freeze-thaw (cFT) process on mouse RBCs. a, cFT process promotes erythrocyte cell lysis and induces the formation of senescent like erythrocyte ghost (SEGs). The SEGs formation process was monitored using KEYENCE BZ-X series all in one fluorescence microscope and the samples were labeled with CyAm7. (Scale bar 50 µm). b, Schematic outline…
