Published: September 2023

AbstractThe present research endeavors to examine the moderating effect of firm size on the relationship between the tenure of the audit committee chair and the board of directors with sustainability disclosure. Data from 592 non‐financial firms listed on the ASE from 2014 to 2021 were analyzed. The findings indicated that a longer tenure of a board of directors leads to increased sustainability disclosure, and firm size positively moderates this relationship. Moreover, the research outcomes indicated that the audit committee chair tenure had a positive yet non‐significant correlation with sustainability disclosure, with no moderating effect of firm size on this relationship. This study provides valuable insights for stakeholders, including investors, managers, and regulators, particularly in developing economies, by demonstrating the influence of corporate governance (CG) on sustainable development. The examination of firm size as a moderating factor offers a unique contribution to the existing literature, thus providing a deeper understanding of the indirect impact of CG on sustainability reporting.
The Scent of Change: Sustainable Fragrances Through Industrial Biotechnology
Authors: Michailidou Freideriki 
Published: September 2023

AbstractCurrent environmental and safety considerations urge innovation to address the need for sustainable high‐value chemicals that are embraced by consumers. This review discusses the concept of sustainable fragrances, as high‐value, everyday and everywhere chemicals. Current and emerging technologies represent an opportunity to produce fragrances in an environmentally and socially responsible way. Biotechnology, including fermentation, biocatalysis, and genetic engineering, has the potential to reduce the environmental footprint of fragrance production while maintaining quality and consistency. Computational and in silico methods, including machine learning (ML), are also likely to augment the capabilities of sustainable fragrance production. Continued innovation and collaboration will be crucial to the future of sustainable fragrances, with a focus on developing novel sustainable ingredients, as well as ethical sourcing practices.
Delays in transferring patients from prisons to secure psychiatric hospitals: An international systematic review
Authors: Sales Christian P. , Forrester Andrew , Tully John 
Published: September 2023

AbstractBackgroundTransfer to a psychiatric hospital of prisoners who need inpatient treatment for a mental disorder is an important part of prison healthcare in the UK. It is an essential factor in ensuring the principle of equivalence in the treatment of prisoners. In England and Wales, delays in transferring unwell prisoners to hospital were identified by the 2009 Bradley Report. There has been no subsequent systematic review of progress in so doing nor a corresponding appraisal of transfer arrangements in other parts of the world.AimTo conduct a systematic review of international literature about transfers of mentally unwell individuals from prison to hospital for the treatment of mental disorder since 2009.MethodEight databases were searched for data‐based publications using terms for prison and transfer to hospital from 1 January 2009 to 4 August 2022. Inclusion criteria limited transfer to arrangements for pre‐trial and sentenced prisoners going to a health service hospital, excluding hospital orders made on the conclusion of criminal hearing.ResultsIn England, four articles were identified, all showing that transfer times remain considerably longer than the national targets of 14 days (range, 14 days to >9 months); one study from Scotland found shorter mean transfer times, but more patients had been transferred to psychiatric intensive care units than to secure forensic hospitals. There were only two studies that investigated prison to hospital transfers for mental disorder from outside the UK and only one reported time‐to‐transfer data.ConclusionsFindings from this literature review highlight failures to resolve transfer delays in England and provide little evidence about the problem elsewhere. Given the lack of data, it is unclear whether other countries do not have this problem or simply that there has been no research interest in it. A possible confounding factor here is that, in some countries, all treatment for prisoners’ mental disorders occurs in prison. However, the principle that prisons are not hospitals seems important when people need inpatient care. Prospective, longitudinal cohort studies are urgently needed to map transfer times and outcomes.

AbstractBackgroundSeverely calcified coronary lesions present a particular challenge for percutaneous coronary intervention.AimsThe aim of this randomized study was to determine whether coronary intravascular lithotripsy (IVL) is non‐inferior to rotational atherectomy (RA) regarding minimal stent area (MSA).MethodsThe randomized, prospective non‐inferiority ROTA.shock trial enrolled 70 patients between July 2019 and November 2021. Patients were randomly (1:1) assigned to undergo either IVL or RA before percutaneous coronary intervention of severely calcified coronary lesions. Optical coherence tomography was performed at the end of the procedure for primary endpoint analysis.ResultsThe primary endpoint MSA was lower but non‐inferior after IVL (mean: 6.10 mm2, 95% confidence interval [95% CI]: 5.32–6.87 mm2) versus RA (6.60 mm2, 95% CI: 5.66–7.54 mm2; difference in MSA: −0.50 mm2, 95% CI: −1.52–0.52 mm2; non‐inferiority margin: −1.60 mm2). Stent expansion was similar (RA: 0.83 ± 0.10 vs. IVL: 0.82 ± 0.11; p = 0.79). There were no significant differences regarding contrast media consumption (RA: 183.1 ± 68.8 vs. IVL: 163.3 ± 55.0 mL; p = 0.47), radiation dose (RA: 7269 ± 11288 vs. IVL: 5010 ± 4140 cGy cm2; p = 0.68), and procedure time (RA: 79.5 ± 34.5 vs. IVL: 66.0 ± 19.4 min; p = 0.18).ConclusionIVL is non‐inferior regarding MSA and results in a similar stent expansion in a random comparison with RA. Procedure time, contrast volume, and dose‐area product do not differ significantly.

AbstractBackgroundPreprocedural computed tomography planning improves procedural safety and efficacy of transcatheter aortic valve implantation (TAVI). However, contemporary imaging modalities do not account for device‐host interactions.AimsThis study evaluates the value of preprocedural computer simulation with FEops HEARTguideTM on overall device success in patients with challenging anatomies undergoing TAVI with a contemporary self‐expanding supra‐annular transcatheter heart valve.MethodsThis prospective multicenter observational study included patients with a challenging anatomy defined as bicuspid aortic valve, small annulus or severely calcified aortic valve. We compared the heart team's transcatheter heart valve (THV) planning decision based on (1) conventional multislice computed tomography (MSCT) and (2) MSCT imaging with FEops HEARTguideTM simulations. Clinical outcomes and THV performance were followed up to 30 days.ResultsA total of 77 patients were included (median age 79.9 years (IQR 74.2–83.8), 42% male). In 35% of the patients, preprocedural planning changed after FEops HEARTguideTM simulations (change in valve size selection [12%] or target implantation height [23%]). A new permanent pacemaker implantation (PPI) was implanted in 13% and >trace paravalvular leakage (PVL) occurred in 28.5%. The contact pressure index (i.e., simulation output indicating the risk of conduction abnormalities) was significantly higher in patients with a new PPI, compared to those without (16.0% [25th–75th percentile 12.0–21.0] vs. 3.5% [25th–75th percentile 0–11.3], p < 0.01) The predicted PVL was 5.7 mL/s (25th–75th percentile 1.3–11.1) in patients with none‐trace PVL, 12.7 (25th–75th percentile 5.5–19.1) in mild PVL and 17.7 (25th–75th percentile 3.6–19.4) in moderate PVL (p = 0.04).ConclusionFEops HEARTguideTM simulations may provide enhanced insights in the risk for PVL or PPI after TAVI with a self‐expanding supra‐annular THV in complex anatomies.
Real‐time 3D–3D image fusion of CTA/CBCT roadmap fluoroscopy in the transcatheter mitral intervention

Published: September 2023

AbstractAbsence of periprocedural visualization of three‐dimensional (3D) left heart anatomy and its surrounding structures in fluoroscopy may reduce the rate of successful transcatheter mitral valve repair. We proposed a multimodal imaging strategy based on 3D computed tomography (CT) angiography and 3D cone beam CT fusion images, which enabled real‐time visual inspection of 3D cardiac structures on fluoroscopy, to optimize transcatheter mitral intervention. This new image fusion technology, together with standard transesophageal echocardiography guidance, improved the efficiency and safety of the procedure, and could be considered as a new workflow for transcatheter mitral valve intervention.
Electrochemical C‐N Coupling on Tri‐metallic Mo‐embedded Graphdiyne towards Efficient Urea Synthesis

Published: September 2023

AbstractSynthesis of urea by electrochemical C−N coupling is a promising alternative to the conventional approaches. A metal‐cluster catalyst generally possesses multi‐atomic active sites and can achieve co‐adsorption and activation of several species. As a two‐dimensional porous material, graphdiyne (GDY) is predicated to be a good substrate for loading a metal cluster. In this study, tri‐metallic Mo‐embedded graphdiyne (Mo3@GDY) stands out for efficient urea synthesis among several TM3@GDY (TM=Mo, Fe, Co, Ni and Cu), based on density functional theory (DFT) computations. The co‐adsorption of side‐on N2 and end‐on CO on Mo3@GDY is benefit to the formation of the urea precursor *NCON with a negative free energy change (−0.66 eV). The final hydrogenation step is the potential‐determining step (PDS) with a medium onset potential (‐0.71 V). This work extends the application of GDY and first provides a new approach for the electrochemical synthesis of urea by loading tri‐metallic atoms on GDY.
Modeling properties of autoclaved aerated concrete (AAC) by different pore size
Authors: Walczak Paweł 
Published: September 2023

AbstractAutoclaved aerated concrete (AAC) is a very popular and porous material, which is foamed in a production process by using aluminum powder. The research program explores the influence of different particle size distributions for properties of AAC with different densities. The compressive strength, thermal conductivity, and shrinkage can be improved by changing the pore size. The research program focused on different density classes of AAC. The pore sizes were changed by using different aluminum powder, different water‐to‐solid ratio, and different starting temperature of the concrete mix. All tests were made on a technological scale and all properties were tested according to EN 771‐4:2011+A1:2015 standard. All samples were tested for dry density, compressive strength, thermal conductivity, shrinkage, and phase composition. The change in pore size can influence not only the AAC properties but also the amounts of raw materials used in the production process and CO2 consumption in its cycle life.

Published: September 2023

AbstractThe compressive strength of the columns was tested on six models made of AAC (autoclaved aerated concrete) masonry elements. Three models were built without strengthening, while the others were made circumferentially strengthened with the FRCM system. The columns were made with cross‐sectional dimensions of 0.18 × 0.18 m and a height of 1.90 m. During the test, strains and the manner of model cracking were also observed. The reinforcement increased the compressive strength by 20%. The test results were compared with the results of analytical calculations.
Achieving the 2025 future homes energy and carbon standard for England using AAC masonry
Authors: Fudge Clifford , Hopkin Tony 
Published: September 2023

AbstractIn 2019, the Government for England published a consultation document on the changes to energy conservation and ventilation in homes for 2025, with an interim change effective from 2022. The 2025 proposed target was issued as the “Future Homes Standard.” The Standard is aiming to produce highly efficient non‐domestic buildings which use low‐carbon heat and have the best fabric standards possible. Buildings built to the Future Buildings Standard will be zero carbon ready, with the ability to decarbonize over time alongside the national grid without any further energy efficiency retrofit work. The target for 2025 is effectively some 80% improvement in energy and carbon compared to the 2013 regulation. Midland Heart Housing Association decided to trial the various options available in the Future Homes Standard under a project called “Project 80.” This comprises an initial development of 12 family homes, constructed with a mix of AAC and aggregate concrete masonry. The first residents moved into their homes in 2022 and have gone through training to understand how the technologies will work in their homes. The homes model how to do this in three different ways, using different technologies. The constructions using AAC are given in this paper, with the technical details of the build.
BIM—A new paradigm for building and maintaining a manufacturer‐architect relationship
Authors: Piekunko‐Mantiuk Iwona , Trusiewicz Piotr 
Published: September 2023

AbstractThe adoption of BIM (Building Information Modeling) technology significantly impacts the ways, in which the building industry operates. This technology not only provides all industry participants with numerous advantages, but also brings new types of relationships and ways in which it can be utilized. Taking into account the fact that many companies have incorporated relationship marketing into their strategies, manufacturers of building materials should look to ways of digitalization to shape collaboration with architects most of all. It seems inevitable when considering that relationship marketing paves the way to competitive value creation. In addition, relationships equip marketers with data and knowledge, which could play a significant role in developing markets and new products, as well as supporting sales departments by providing solid leads. The aim of this paper was to indicate what kind of role BIM methodology could have in establishing long‐term relationships in the manufacturer‐architect line. In research, we focus on the manufacturer's perspective and show possibilities for long‐term cooperation with architects. In this research, a mixed methodology approach has been used, in which a systematic review of the literature, an own survey on a group of architects, and a case study based on a solution used by one of the clients of the BIM ALLY. The possibilities of using BIM as a marketing communication channel, sales channel, and channel for obtaining key data and information about the users of digital models were proven and indicated.
Belite cement clinker from autoclaved aerated concrete waste fines with high sulfate content

Published: September 2023

AbstractThe processing of belite cement clinker in a rotary kiln at about 1000°C in a CO2 atmosphere is a new recycling option for Autoclaved Aerated Concrete (AAC) waste that otherwise must be landfilled. Waste fine fractions from a sorting facility enriched in sulfate due to intermixing with waste plaster have been processed. During clinkering the cement clinker phase belite (Ca2SiO4) besides technical ellestadite, (Ca10(SiO4)3(SO4)3Cl2), or ternesite, (Ca5(SiO4)2SO4), are formed, depending on the addition of flux minerals. However, not all phases of the novel clinker react hydraulically. Whereas ternesite reacts with water, ellestadite forms complex solid solution series (Ca/Pb, SO4/PO4), which may be used as an insoluble reservoir mineral for undesirable constituents, such as phosphates and chlorides. The produced clinker has been successfully used to partially substitute OPC in AAC production in technical trials. Waste quantities and landfill costs are minimized, while at the same time, CO2 emissions and the primary resource consumption of AAC production are reduced. Joint work with industrial companies is underway to increase technology readiness. Particularly large reduction effects on CO2 emissions can be achieved through electrical heating of the rotary kiln.

AbstractAutoclaved Aerated Concrete (AAC) is a special composite and widely accepted construction material owing to good durability, raw material availability, and environmentally friendly nature. Nevertheless, the continuing focus of the industry remains in cost optimization and maximizing the performance of blocks. The investigations related to the effects of admixtures in AAC are continuing globally with the objective of improving the productivity and strength improvement of AAC blocks. It is now well documented that the behavior of admixtures in conventional concrete and AAC is different, partly due to the low quantities of cement in a mix design and production systems. Hence it is essential to conduct a detailed investigation for finding the suitability of chemical admixtures. This review paper shows the trend of admixtures used in AAC and describes how they affect the rheological characteristics, setting time, and mechanical properties. From the review, it is clear that the performance of admixtures mainly depends on the type of binder, type, and dosage of admixtures. PCE‐based superplasticizers and performance enhancers are generally recommended to provide incremental improvement in flow behavior and mechanical strength. However, it is important to note the mix design and complex interplay of various materials have a large impact on the performance of any admixture employed. The investigations thus far indicate that chemical admixtures also impact the initial curing times without sacrificing the mechanical properties of AAC. In general, the usage of admixtures can enhance the strength of blocks between 5% and 15% depending on the type and quantity of admixture.
Influence of a mortar type on shrinkage of autoclaved aerated concrete
Authors: Walczak Paweł 
Published: September 2023

AbstractShrinkage is one of the most important properties of Autoclaved Aerated Concrete (AAC), which is tested in accordance with EN 680:2008. Unfortunately, in construction, we have only a situation where AAC blocks are connected together with different types of mortar: standard mortar, thin joint mortar, or polyurethane glue. The shrinkage of masonry structures is determined by properties of AAC and properties of the used glue system. This research program, based on the standard EN 680, included AAC specimens of different density classes connected with various types of mortar: thin joint mortar with different compressive strengths, manufactured by various producers, and polyurethane glue. Specimens were prepared in accordance with the standard EN 680:2008, but connected by mortars in two different directions. Test results can be helpful in designing masonry structures.

Authors: Walczak Paweł 
Published: September 2023

AbstractCarbonation is a natural process in all materials based on burnt lime and cement. Many publications treat the influence of carbonation on the properties of Autoclaved Aerated Concrete (AAC), especially on compressive strength. The influence of carbonation on compressive strength, dry density, shrinkage, and thermal conductivity on AAC in different density classes (350–600) was a subject of this research program. AAC specimens were subjected to accelerated carbonation in a climate chamber at a temperature of 20°C, 65% RH of a period of 14 days with a CO2 concentration of 0.5%. The different moisture content of specimens was used in the research program. All tests were conducted in accordance with EN 771‐4:2011+A1:2015. To determine the phase content and microstructure change the XRD analysis was used.

Published: September 2023

AbstractThis article describes BIM‐related issues. BIM is still a hot topic. Many manufacturers offer their tools to designers. However, not all of them are practical tools that designers will use. Even some will not be accepted by designers. BIM tools should have a number of advantages, thanks to which they will determine their usefulness and practical application in the design and implementation of buildings. The article contains values that should be characterized by BIM tools that will meet the expectations of designers. The article also addresses the issue of the different approach of designers and design offices to BIM tools. The article was created on the basis of design experience and in cooperation with designers.
