Host preference of a tree-killing bark beetle across a geographic boundary separating host species
<p><span>The life cycles of bark beetles are intimately linked to their host species. Therefore, bark beetle species are expected to show traits that vary among different host species and across geographic ranges. The taxonomic proximity of host tree species can also influence host selection. <em>Abies</em> species native to Japan are genetically classified into three phylogenetic groups. Their natural distributions are separated by a </span><span>distinct biogeographic boundary in Japan (i.e. the Tsugaru Strait, also referred to as Blakiston's Line)</span><span>. Especially, <em>A. sachalinensis</em> is the only species native to Hokkaido, north of the </span><span>Tsugaru Strait</span><span>. I, therefore, investigated the host preference of <em>Polygraphus proximus</em> Blandford within four allopatrically distributed <em>Abies</em> species across the north and south of the Tsugaru Strait</span> <span>through field surveys and field choice experiments</span><span>.</span> <span>Field observations and field host-choice bioassays showed that <em>A. sachalinensis</em> was less severely attacked by <em>P. proximus</em> than was <em>A. veitchii</em> on both sides of the Tsugaru Strait.</span><span> The beetles also </span><span>preferred to attack <em>A. firma</em> (which </span><span>belongs to a genetically distinct group (i.e., the section <em>Momi</em>) from that of <em>A. veitchii</em> and <em>A. sachalinensis</em> (i.e., the section <em>Balsamea</em>)), over </span><em><span>A</span></em><span><em>. sachalinensis</em> in both Hokkaido and Honshu</span><span>.

Effects of marking, chilling and mechanical separation on the blood feeding success, fecundity and fertility of wMel-infected Aedes aegypti.
<p>In field trial II (Nausori 2019), mosquitoes were sampled from the emergence cages (rearing control), after cold-immobilization at 4°C for 30 minutes (immobilization control) and at the end of UAV flights (aerial). Collected mosquitoes were sorted into cages of 50 females and 15 males. Females were allowed to blood feed and the blood feeding success was determined. Blood fed females were kept and allowed to oviposit and fecundity is shown as eggs per female. Eggs were hatched and larvae were counted 48 hours post hatching to determine fertility. Statistical analysis was performed using ordinary one-way ANOVA. NS = Not statistically significant and ND = Not done.</p>
Data related to the utilisation of source-separated biowaste for the production of bio-based chemicals
<p><span>The main objective of this dataset was to demonstrate the technological solution of biosolvents production (mainly bioethanol) via the utilisation of urban biowaste within the city context of Athens, Greece. More specifically, the aim of the dataset is the demonstration of a pre-existing system, namely PILOT 5 for the production of bioethanol. </span></p> <p><span>The results achieved were very promising for the viability of the process, either with dried or wet feedstock. It is important to consider the energy consumption, as it constitutes more than 50% in the overall ethanol production cost. In comparison, the total energy consumption for the production of ethanol with dried feedstock is 26% higher than with wet feedstock.</span><span> </span><span>The most energy-intensive stage is drying, followed by distillation. </span></p> <p> </p>
Separable processes for live "in-person" and "zoom-like" faces
<p>Increased reliance on Zoom-like (webcam) platforms for interpersonal communications has raised the question of how this new virtual format compares to real face-to-face interactions. This question is also relevant to current models of face processing. Neural coding of simulated faces engages feature-selective processes in the ventral visual stream and two-person live face-to-face interactions engage additional face processes in the lateral and dorsal visual streams. However, it is not known if and/or how live in-person face processes differ from live virtual face processes because the faces and tasks are essentially the same. Current views of functional specificity predict no neural difference between the virtual and live conditions. Here we compare the same live faces viewed both over a video format and in person with measures of functional near-infrared spectroscopy (fNIRS), eye tracking, pupillometry, and electroencephalography (EEG). Neural activity was increased in dorsal regions for in-person face gaze and was increased in ventral regions for virtual face gaze. Longer dwell times on the face, increased arousal indexed by pupil diameter, increased neural oscillation power in the theta band, and increased cross-brain coherence were also observed for the in-person face condition. These findings highlight the fundamental importance of real faces and natural interactions for models of face processing.</p>

New Azo-DMOF-1 MOF as a photo-responsive low-energy CO2 adsorbent and its exceptional CO2/N2 separation performance in mixed matrix membranes
<p>Data repository for manuscript, published in <em>ACS Applied Materials & Interfaces</em>, <strong>2018</strong>, <em>10</em> (40), pp 34291–34301, <a href="https://dx.doi.org/10.1021/acsami.8b12261">http://dx.doi.org/10.1021/acsami.8b12261</a></p> <p><strong>Abstract</strong></p> <p>A new generation-2 light-responsive metal–organic framework (MOF) has been successfully synthesized using Zn as the metal source and both 2-phenyldiazenyl terephthalic acid and 1,4-diazabicyclo[2.2.2]octane (DABCO) as the ligands. It was found that Zn-azo-dabco MOF (Azo-DMOF-1) exhibited a photoresponsive CO<sub>2</sub> adsorption both in static and dynamic condition because of the presence of azobenzene functionalities from the ligand. Further application of this MOF was evaluated by incorporating it as a filler in a mixed matrix membrane for CO<sub>2</sub>/N<sub>2</sub> gas separation. Matrimid and polymer of intrinsic microporosity-1 (PIM-1) were used as the polymer matrix. It was found that Azo-DMOF-1 could enhance both the CO<sub>2</sub> permeability and selectivity of the pristine polymer. In particular, the Azo-DMOF-1–PIM-1 composite membranes have shown a promising performance that surpassed the 2008 Robeson Upper Bound.</p>

Supporting data for "Cellulose separators with integrated carbon nanotube interlayers for lithium-sulfur batteries: an investigation into the complex interplay between cell components"
<p>This is the dataset of electrochemical experiments for our publication "Cellulose separators with integrated carbon nanotube interlayers for lithium-sulfur batteries: an investigation into the complex interplay between cell components". This archive contains the raw data and scripts written in R used in the analysis and presentation of the results in this manuscript.</p> <p><strong>Abstract for the manuscript:</strong></p> <p>This work aims to address two major roadblocks in the development of lithium-sulfur (Li-S) batteries: the inefficient deposition of Li on the metallic Li electrode and the parasitic “polysulfide redox shuttle”. These roadblocks are here approached, respectively, by the combination of a cellulose separator with a cathode-facing conductive porous carbon interlayer, based on their previously reported individual benefits. The cellulose separator increases cycle life by 33%, and the interlayer by a further 25%, in test cells with positive electrodes with practically relevant specifications and a relatively low electrolyte/sulfur (E/S) ratio. Despite the prolonged cycle life, the combination of the interlayer and cellulose separator <em>increases</em> the polysulfide shuttle current, leading to reduced Coulombic efficiency. Based on XPS analyses, the latter is ascribed to a change in the composition of the solid electrolyte interphase (SEI) on Li. Meanwhile, electrolyte decomposition is found to be slower in cells with cellulose-based separators, which explains their longer cycle life. These counterintuitive observations demonstrate the complicated interactions between the cell components in the Li-S system and how strategies aiming to mitigate one unwanted process may exacerbate another. This study demonstrates the value of a holistic approach to the development of Li-S chemistry.</p> <p>Manuscript preprint <a href="http://dx.doi.org/10.26434/chemrxiv.8835728">available at ChemRxiv</a> (pending approval as of 9/7/19).</p>
A Review on Emerging Organic-containing Microporous Material Membranes for Carbon Capture and Separation
<p><strong>Published article:</strong> Prasetya, N., Himma, N. F., Doddy Sutrisna, P., Wenten, I. G. & Ladewig, B. P. <em>Chem. Eng. J.</em> 123575 (2019). <a href="https://doi.org/10.1016/j.cej.2019.123575">https://doi.org/10.1016/j.cej.2019.123575</a></p> <p><strong>Abstract</strong></p> <p>Membrane technology has gained great attention as one of the promising strategies for carbon capture and separation. Intended for such application, membrane fabrication from various materials has been attempted. While gas separation membranes based on dense polymeric materials have been long developed, there is a growing interest to use porous materials as the membrane material. This review then focuses on emerging porous materials to be used for the fabrication of membranes that are designed for CO<sub>2</sub>separation. Criteria for selecting microporous material are first discussed, including physical and chemical properties, and parameters in membrane fabrication. Membranes based on emerging porous materials,such as metal-organic frameworks, porous organic frameworks, and microporous polymers,are then reviewed. Finally, special attention is given to recent advances, challenges, and perspectives in the development of such membranes for carbon capture and separation. </p>
