Graphene presents unique optoelectronic properties, making it attractive for the development of a wide range of new and advanced technological applications such as high-speed photodetectors and all-optical modulators. The study and control of the generated carriers in graphene, namely their ultrafast relaxation dynamics, are of great importance for these applications. Here, we report the ultrafast
Effective electron supply to produce ammonia in photoelectrochemical nitrogen reduction reaction (PEC NRR) remains challenging due to the sluggish multiple proton-coupled electron transfer and unfavorable carrier recombination. Herein, InP quantum dots decorated with sulfur ligands (InP QDs-S2−) bound to MIL-100(Fe) as a benchmark catalyst for PEC NRR is reported. It is found that MIL-100(Fe) can
Many insects depend on high-altitude, migratory movements during part of their life cycle. The daily timing of these migratory movements is not random, e.g. many insect species show peak migratory flight activity at dawn, noon or dusk. These insects provide essential ecosystem services such as pollination but also contribute to crop damage. Quantifying the diel timing of their migratory flight and
From vision to sound. In this piece I was interested to transfer special properties of color into sound. This transference occurred in two ways: 1) Timbre as representing some color property; 2) Sound sequences/gestures as representing some color property.These transferences are metaphorical and inspirational, not systematic nor literal in any sense.Some of these special properties include:ACHROMA
Pulmonary tuberculosis (TB) causes progressive and irreversible damage to lung tissue, a damage that may not fully resolve after treatment. Mycobacterial vesicles (MVs), which are poorly understood, may contribute to TB pathology. This study investigated the effects of stress, such as treatment with conventional TB antibiotics rifampicin, isoniazid, ethambutol, or treatment with an antimycobacteri
Despite evidence that cesarean section rates above 10 percent at the population level do not reduce maternal or neonatal mortality, global rates continue to rise and are projected to reach 30 percent by 2030. The factors behind this increase are complex and vary across contexts, emphasizing the need for a local understanding in order to design and implement effective interventions to curb overuse.
Marine sediments have been suggested as a reservoir for pathogenic bacteria, including Escherichia coli. The origins, and properties promoting survival of E. coli in marine sediments (including osmotolerance, biofilm formation capacity, and antibiotic resistance), have not been well-characterized. Phenotypes and genotypes of 37 E. coli isolates from coastal marine sediments were characterized. The
Aim: Opioids might be harmful to the developing brain and dosing accuracy is important. We aimed at investigating fentanyl effects on cortical activity in infants using computational re-analysis of bedside recorded EEG signals. Methods: Fifteen infants born at median 26.4 gestational weeks (range 23.3–34.1), with a birth weight 740 grams (530–1420) and postnatal age 7 days (5–11) received fentanyl
At MAX IV laboratory the linac is used to inject into the two rings but also to drive the FemtoMAX beamline, which is a source of (incoherent) short pulses in the Hard X-ray range.In this contribution we present the design and simulations for a new mode of operation of the linac that would allow to generate coherent ultra-short FEL pulses in the soft X-ray domain. Preliminary simulations indicate
Background: Deep learning methods are revolutionizing natural science. In this study, we aim to apply such techniques to develop blood type prediction models based on cheap to analyze and easily scalable screening array genotyping platforms. Methods: Combining existing blood types from blood banks and imputed screening array genotypes for ~111,000 Danish and 1168 Finnish blood donors, we used deep
Purpose: The purpose of this study is to scrutinize the connection between creativity and innovation in the context of public healthcare. This is achieved by applying the theoretical concept of employee-driven innovation (EDI) to explore employees’ perceptions of their creative engagement in innovation processes, as well as to capture the managerial implications of setting up such processes in the
Background: Cardiovascular diseases (CVDs) are the most common cause of death worldwide. CVDs share heterogeneous pathophysiologic mechanisms, one of which includes increased oxidative stress. Main Body: Surplus levels of reactive oxygen species induce damage to cellular macromolecules such as DNA, proteins, and lipids. Increased reactive oxygen species result in decreased nitric oxide availabilit
Malaria caused by Plasmodium falciparum leads to the destruction of red blood cells (RBCs). A better understanding of how naturally immune individuals control infections should be valuable for future vaccine studies. Antibodies against RBCs and RBC surface antigens were measured together with different inflammatory markers in healthy adults living in a malaria endemic area of Uganda and compared t
The S-scheme mechanism in photocatalysis offers a promising approach to significantly enhance photoreductive activity. Here, using Bi dots as electronic media, and by changing the amount of added C@CuO on the surface of flower-shaped Bi2MoO6, a diverse range of CBM-x heterojunctions, were synthesized using a multi-step approach that incorporated solvothermal preparation and calcination methods. CB
Background: Cancer affects not only the person with the disease but those around them. Being a family member is described as strenuous and, often, associated with stress, anxiety and feelings of loneliness. There is a heightened risk of distress for family of those with fast-progressing, severe oesophageal or gastric cancer. Early palliative care involving family is vital yet often overlooked. In
Dose conversion coefficients attempt to harmonize the material-, location-, and exposure-dependent results from retrospective dosemeters. The issues and uncertainties arising from dose conversion are explored within the framework of an interlaboratory comparison exercise in which mobile phones were positioned around anthropomorphic phantoms and exposed to non-uniform photon fields, with the glass
This article compares and explores vacuum foam-drying as an alternative drying technology to freeze-drying and spray drying for a recombinant human lipase as the model protein. Materials characteristics such as structure, surface composition and the solid-state properties of the dry materials were compared and investigated. Moreover, the technical functionality in terms of reconstitution character
Poly-ADP-ribose polymerases (PARPs) catalyze transfer of ADP-ribose from NAD(+) to specific residues in their substrate proteins or to growing ADP-ribose chains. PARP activity is involved in processes such as chromatin remodeling, transcription control, and DNA repair. Inhibitors of PARP activity may be useful in cancer therapy. PARP2 is the family member that is most similar to PARP1, and the two
