Building a Library for Catalysts Research Using High‐Throughput Approaches

AbstractThe development of new catalysts is an urgent task in chemistry research because of the increasing demands for higher productivity and efficiency in modern industrial chemistry. High‐throughput (HT) technologies have emerged as powerful accelerators for the discovery of new catalytic materials. Generally, HT techniques involve HT computational screening of catalytic materials and HT experimental approaches. Significant progress has been made in discovering and optimizing catalysts, which demonstrates the speed and economic advantages of HT methods in a matter of process within days and even hours, in contrast with traditional time‐consuming trial and error experiments. From this perspective, the key processes of HT technologies for building a catalysts library are highlighted, including the virtual lab construction based on informatics tools and experimental data lab involving the following processes: 1) design of experiments; 2) reactants prepared manually or automatically; 3) constructing reactor that can well control the variations including materials diversity and reaction conditions (e.g., temperature and reaction time); 4) parallel characterization of fabricated catalysts. Moreover, the correlation between virtual lab and experimental data is discussed to inspire explorations in this field. Furthermore, several remaining challenges of HT technologies accompanied by possible research directions are presented to promote efforts in catalysts library creation.

Ischaemia-free liver transplantation in humans: a first-in-human trial.

SummaryBackground Ischaemia-reperfusion injury is considered an inevitable component of organ transplantation, compromising organ quality and outcomes. Although several treatments have been proposed, none has avoided graft ischaemia and its detrimental consequences.Methods Ischaemia-free liver transplantation (IFLT) comprises surgical techniques enabling continuous oxygenated blood supply to the liver of brain-dead donor during procurement, preservation, and implantation using normothermic machine perfusion technology. In this non-randomised study, 38 donor livers were transplanted using IFLT and compared to 130 conventional liver transplants (CLT).Findings Two recipients (5•3%) in the IFLT group experienced early allograft dysfunction, compared to 50•0% in patients receiving conventional transplants (absolute risk difference, 44•8%; 95% confidence interval, 33•6-55•9%). Recipients of IFLT had significantly reduced median (IQR) peak aspartate aminotransferase levels within the first week compared to CLT recipients (365, 238-697 vs 1445, 791-3244 U/L, p<0•001); likewise, median total bilirubin levels on day 7 were significantly lower (2•34, 1•39-4•09 mg/dL) in the IFLT group than in the CLT group (5•10, 1•90-11•65 mg/dL) (p<0•001). Moreover, IFLT recipients had a shorter median intensive care unit stay (1•48, 0•75-2•00 vs 1•81, 1•00-4•58 days, p=0•006). Both one-month recipient (97•4% vs 90•8%, p=0•302) and graft survival (97.4% vs 90•0%, p=0•195) were better for IFLT than CLT, albeit differences were not statistically significant. Subgroup analysis showed that the extended criteria donor livers transplanted using the IFLT technique yielded faster post-transplant recovery than did the standard criteria donor livers transplanted using the conventional approach.Interpretation IFLT provides a novel approach that may improve outcomes, and allow the successful utilisation of extended criteria livers.Funding This study was funded by National Natural Science Foundation of China, Guangdong Provincial Key Laboratory Construction Projection on Organ Donation and Transplant Immunology, and Guangdong Provincial international Cooperation Base of Science and Technology.Panel: Research in context

Research on the Exploration of Petrochemical Virtual Simulation Laboratory Construction Based on VR Technology

Students' Perceptions of Learning Mathematics Online

This research was motivated by a change from direct learning to online learning. This is due to the Covid-19 pandemic that occurred in early 2020. There are students who think that learning Mathematics online is difficult. So that students have negative perceptions about learning Mathematics online. This study aims to describe students' perceptions about learning Mathematics online in terms of the stages before learning, while studying, and after learning. This research uses a descriptive approach with quantitative methods. The population in this study was students of SMA UNP Laboratory Construction for the 2020/2021 academic year, totaling 621 and sample 243 students. The sample selection used simple random sampling technique. The data collection technique used a questionnaire on students' perceptions about learning Mathematics online with a Likert scale model. Data were analyzed using descriptive statistical analysis techniques. This research as a whole shows that the students' perceptions about learning Mathematics online at the UNP Laboratory Development High School as a whole are in the quite good category with a percentage of 60%. Furthermore, seen from the aspect of the stages before learning is in the quite good category, namely 65%, Then, seen from the aspects of the stages during learning, it was in the quite good category, namely 60%, and seen from the aspect of the stages after learning is in the quite good category, namely by 66%. The implication of this research can later be used as a consideration of guidance and counseling in the school.

Robust detection of non-overlapping ellipses from points with applications to circular target extraction in images and cylinder detection in point clouds

Detection of non-overlapping ellipses from 2-dimensional (2D) edge points is an essential step towards solving typical photogrammetry problems pertaining to feature detection, calibration, and registration of optical instruments. For instance, circular and spherical black and white calibration and registration targets are represented as ellipses in images. Furthermore, the intersection of a cut plane with cylindrical point clouds generates 2D points following elliptic patterns. To this end, this study proposes a collection of new methods for the automatic and robust detection of non-overlapping ellipses from 2D points. These methods will first be applied to detect circular and spherical targets in images and, second, to detect cylinders in 3D point clouds. The method utilizes the Euclidian ellipticity and a new systematic and generalizable threshold to decide if a set of connected points follow an elliptic pattern. When connected points include outliers, the newly proposed robust Monte Carlo-based ellipse fitting method will be deployed. This method includes three new developments: (i) selecting initial subsamples using a bucketing strategy based on the polar angle of the points; (ii) detecting inlier points by reducing the robust ellipse fitting to a robust circle fitting problem; and (iii) choosing the best inlier set amongst all subsamples using adaptive, systematic, and generalizable selection criteria. A new process is presented to extract cylinders from a point cloud by detecting non-overlapping ellipses from the points projected onto an intersecting cut plane. The proposed methods were compared to established state-of-the-art methods, using simulated and real-world datasets, through the design of four sets of original experiments. The experiments include (i) comparisons of robust ellipse fitting; (ii) sensitivity analysis of the ellipse validation criteria; (iii) comparison of non-overlapping ellipse detection; and (iv) detection of pipes from terrestrial laser scanner point clouds. It was found that the proposed robust ellipse detection was superior to four reliable robust methods, including the popular least median of squares, in both simulated and real-world datasets. The proposed process for detecting non-overlapping ellipses achieved F-measure of 99.3% on real images, compared to 42.4%, 65.6%, and 59.2%, obtained using the methods of Fornaciari, Patraucean, and Panagiotakis, respectively. The proposed cylinder extraction method identified all detectable mechanical pipes in two real-world point clouds collected in laboratory and industrial construction site conditions. The results of this investigation show promise for the application of the proposed methods for automatic extraction of circular targets from images and pipes from point clouds.
