Adding metal-oxide shell layers is a promising route for improving the performance of metal nanoparticles (NPs) in various applications. However, despite the rapidly growing interest and a significant amount of experimental work on metal@metal-oxide NPs, computational modeling is relatively scarce, particularly on the sintering mechanism, which plays a crucial role in both the synthesis and perfor

An interesting subset of nanoparticles is core-shell nanoparticles: encapsulating a core particle of one material with a shell of another material can be utilized to combine and even extend the properties of the respective material. Strategies to synthesize core-shell nanoparticles in the aerosol phase remain relatively unexplored, despite the benefit of the continuous, ambient pressure nature of

The retail landscape is transforming at an unprecedented speed and scale, thereby driving an unparalleled growth in last-mile delivery. The already rapidly growing online sales have been further fueled by the coronavirus pandemic. However, the share of online sales varies greatly among different retail sectors. In grocery retail, the share of online sales is still relatively low even though it is

Abstract: Breast cancers are heterogeneous tumours. Prognostic markers are needed to better profile the patient´s risk, and predictive markers to indicate the expected benefit of systemic treatment. Using gene expression analyses, breast tumours can be divided into intrinsic subtypes. Immunohistochemical (IHC) markers (oestrogen and progesterone receptors (ER and PR), human epidermal growth factor

What caused the recovery from the British Great Depression? A leading explanation - the “expectations channel” - suggests that a shift in expected inflation lowered real interest rates and stimulated consumption and investment. However, few studies have measured, or tested the economic consequences of, inflation expectations. In this paper, we collect high-frequency information from primary and se

How sticky were wages during the Great Depression? Although classic accounts emphasize the importance of nominal rigidity in amplifying deflationary shocks, the evidence is limited. In this paper, I calculate the degree of nominal wage rigidity in the United Kingdom between the wars using new granular data covering millions of wages.I find that nominal wages were more flexible downwards than in mo

Interaction of the T cell receptor (TCR) with an MHC-antigenic peptide complex results in changes at the molecular and cellular levels in T cells. The outside environmental cues are translated into various signal transduction pathways within the cell, which mediate the activation of various genes with the help of specific transcription factors. These signaling networks propagate with the help of v

In 1966, Gallai asked whether every connected graph has a vertex that is common to all its longest paths. The answer to this question is negative. We prove that the answer is positive for outerplanar graphs. Another related question was raised in 1995 at the British Combinatorial Conference: Do any three longest paths in a connected graph have a vertex in common? We prove that, in a connected grap

Over the last years, there have been huge research efforts in the synthesis of advanced nanoparticle heterostructures to promote their performance in photocatalysis.[1] Especially, the combination of metals with semiconductors has been identified as a potential approach to enhance the photocatalytic activity via efficient charge carrier separation enabled by plasmon- exciton coupling.[2] The physi

Vascular plant observances were compiled for 10 well-documented parishes in Scania, southernmost Sweden, from published floras, herbarium specimens, modern inventories, and a large citizen-science database to provide decade-level presence/absence data of species throughout the period 1800–2020. Species-specific plant traits and ecological indicator values were then used to examine functional and e

Sjötrafik har alltid haft en stor betydelse för vårt samhälle genom att transportera gods och människor mellan och inom länder. Transporter till sjöss har stora fördelar associerat till relativt låga klimatutsläpp och transportkostnader. Tyvärr medför sjötrafik även en negativ påverkan på vår miljö. Den negativa påverkan kan till exempel bestå av utsläpp av luftföroreningar, tömning av ballastvatt

Typhoid fever continues to be a health challenge in low-and middle-income countries where access to clean water and sanitation infrastructure is scarce. The non-confirmatory diagnostic method continues to hinder effective diagnosis and treatment, ensuring in a high antimicrobial resistance. This systematic review and meta-analysis aimed to estimate the pooled prevalence and antimicrobial susceptib

OBJECTIVE: The aim of the study was to investigate the associations of total sleep time (TST) and occupational stress based on the Brief Job Stress Questionnaire (BJSQ) with cholesterol levels in an occupational cohort of Japanese office workers. METHODS: The present study is a secondary analysis of a subset of participants from a randomized controlled trial. Participants were 179 employees from 5

Cassava is a vital food-security crop in Sub-Saharan Africa. Cassava crops are, however, severely affected by viral diseases transmitted by members of the whitefly species complex Bemisia tabaci. We have here investigated the role of olfaction in host selection behavior of the cassava whitefly B. tabaci SSA-ESA biotype. Surprisingly, we find that the whiteflies appear to make little use of olfacti

Radical excision of periorbital skin tumors is difficult without sacrificing excessive healthy tissue. Photoacoustic (PA) imaging is an emerging non-invasive biomedical imagi­­ng modality that has potential for intraoperative micrographic control of surgical margins. This is the first study to assess the feasibility of PA imaging for the detection of periocular skin cancer. Eleven patients underwe

The recent finding of the flea beetle species Podagrica fuscicornis (Linné, 1767) in a commercial market garden at Ystad just off the south coast of Skåne (Scania), the southernmost province of Sweden, is discussed. The species was found in August 2010 residing on plants of Lavatera cashmeriensis (Malvaceae), the follwing years in numbers. Old literature records from Sweden of the species (e.g. Gy
