The isolation of graphene in 2004 from graphite was a defining moment for the "birth" field: two-dimensional (2D) materials. In recent years, there has been rapidly increasing number papers focusing on non-graphene layered materials, including transition-metal dichalcogenides (TMDs), because new properties and applications that emerge upon 2D confinement. Here, we review significant advances important developments materials "beyond graphene". We provide insight into theoretical modeling...

The impact of the Ag particle (metal powder in screen printed paste) size on quality thick-film ohmic contacts to high-sheet-resistance emitters Si solar cells is investigated. Spherical was varied range (ultrafine large). Even though ultrathin glass regions are achieved for large paste, giving low specific contact resistance , secondary ion mass spectroscopy measurements showed a higher concentration at p–n junction that increased leakage current and decreased by fill factor (FF) . Pastes...
The water/graphene interface has received considerable attention in the past decade due to its relevance various potential applications including energy storage, sensing, desalination, and catalysis. Most of our knowledge about interfacial water structure next graphene stems from simulations, which use experimentally measured contact angles (WCAs) on (or graphite) estimate water-graphene interaction strength. However, existence a wide spectrum reported WCAs supported graphitic surfaces makes...
For decades, the enzymes of fungus Hypocrea jecorina have served as a model system for breakdown cellulose. Three-dimensional structures almost all H. cellulose-degrading are available, except HjLPMO9A, belonging to AA9 family lytic polysaccharide monooxygenases (LPMOs). These enhance hydrolytic activity cellulases and essential cost-efficient conversion lignocellulosic biomass. Here, using structural spectroscopic analyses, we found that native HjLPMO9A contains catalytic domain family-1...
Robotic assisted laparoscopic pyeloplasty is an emerging, minimally invasive alternative to open in children for ureteropelvic junction obstruction. The procedure associated with smaller incisions and shorter hospital stays. To our knowledge previous outcome analyses have not included human capital calculations, especially regarding loss of parental workdays. We compared perioperative factors patients who underwent robotic at a single institution, regard changes, institutional cost...
In this work, to explain doping behavior of single-layer graphene upon HSSYWYAFNNKT (P1) and HSSAAAAFNNKT (P1–3A) adsorption in field-effect transistors (GFETs), we applied a combined computational approach, whereby peptide was modeled by molecular dynamics simulations, the lowest energy configuration confirmed density functional theory calculations. On basis resulting structures hybrid materials, electronic structure transport calculations were investigated. We demonstrate that π–π stacking...
Sensors for human health and performance monitoring require biological recognition elements (BREs) at device interfaces the detection of key molecular biomarkers that are measurable state indicators. BREs, including peptides, antibodies, nucleic acids, bind to in vicinity sensor surface create a signal proportional biomarker concentration. The discovery BREs with required sensitivity selectivity low concentrations remains fundamental challenge. In this study, we describe an in-silico...
Critical infrastructure components nowadays use microprocessor-based embedded control systems. It is often infeasible, however, to employ the same level of security measures used in general purpose computing systems, due stringent performance and resource constraints Furthermore, as software sits atop relies on firmware for proper operation, software-level techniques cannot detect malicious behavior firmware. In this work, we propose ConFirm, a low-cost technique modifications systems by...
Familial isolated GH deficiency type II is an autosomal dominant form of short stature, associated in some families with mutations that result missplicing to produce del32–71-GH, a protein cannot fold normally.

Risk of testicular germ cell tumors (TGCT) is consistently associated with a history cryptorchidism (CO) in epidemiologic studies. Factors modifying the association may provide insights regarding etiology TGCT and suggest basis for individualized care CO. To identify modifiers CO-TGCT association, we conducted comprehensive, quantitative evaluation data.Human studies cited PubMed or ISI Web Science indices through December 2011 selected unpublished data were reviewed to 35 articles one...
Abstract The fabrication of nanoscale devices requires architectural templates on which to position functional molecules in complex arrangements. Protein scaffolds are particularly promising for nanomaterials due inherent molecular recognition and self-assembly capabilities combined with genetically encoded functionalities. However, difficulties engineering protein quaternary structure into stable well-ordered shapes have hampered progress. Here we report the development an ultrastable...
Abstract Heterostructures consisting of two-dimensional materials have shown new physical phenomena, novel electronic and optical properties device concepts not observed in bulk material systems or purely three dimensional heterostructures. These effects originated mostly from the van der Waals interaction between different layers. Here we report that a platform can be provided by heterostructures 2D graphene with metal oxide (TiO 2 ). Our direct synthesis graphene/TiO heterostructure is...
Real-time sensing of proteins, especially in wearable devices, remains a substantial challenge due to the need convert binding event into measurable signal that is compatible with chosen analytical instrumentation. Impedance spectroscopy enables real-time detection via either measuring electrostatic interactions or electron transfer reactions while simultaneously being amenable miniaturization for integration form-factors. To create more robust methodology optimizing impedance-based sensors,...

Understanding the factors that influence interaction between biomolecules and abiotic surfaces is of utmost interest in biosensing biomedical research. Through phage display technology, several peptides have been identified as specific binders to material surfaces, such gold, graphene, silver, so forth.

Breathing-air quality within commercial airline cabins has come under increased scrutiny because of the identification volatile organic compounds (VOCs) from engine bleed air used to provide oxygen cabins. Ideally, a sensor would be placed pipe itself, enabling detection before it permeated through and contaminated entire cabin. Current gas-phase sensors suffer issues with selectivity, do not have appropriate form factor, or are too complex for deployment. Here, we chose isopropyl alcohol...
