Published: December 2024

AbstractConsiderable efforts have been devoted to augmenting the performance of displacement sensors constrained by quantum noise, particularly within high‐precision applications such as gravitational wave detection. Frequency‐dependent squeezing methodologies have adeptly exceeded the standard quantum limit in optomechanical force measurements, catalyzing profound advancements in the field. Concurrently, notable strides in integrated photonics have paved the way for the realization of integrated Kerr quantum frequency combs (QFCs). In this work, a sophisticated platform designed for the creation of Einstein–Podolsky–Rosen (EPR)‐entangled QFCs utilizing on‐chip silicon nitride microring resonators is presented. This platform facilitates an exhaustive analysis and optimization of entanglement performance, establishing a robust framework for noise mitigation. By incorporating the quantum dynamics of Kerr nonlinear microresonators, the system accommodates at least 12 continuous‐variable quantum modes, including 6 pairs of concurrently EPR‐entangled states. Moreover, through precise tuning of the detection angle of the idler mode, the signal mode transitions into a single‐mode squeezed state. Harnessing the frequency‐dependent nature of this detection angle enables the achievement of frequency‐dependent squeezing. A comparative analysis under different dispersion conditions is also presented.
Could Metamaterials be the Next Frontier of Catalysis?
Authors: Loh Joel Y. Y. 
Published: December 2024

AbstractPlasmonic catalysis, whereby either an optically resonating metal couples to a catalytic material or a catalytic metal particle achieves optical resonance, has been a mainstay of photo‐catalysis research for the past few decades. However, a new field of metal‐dielectric metamaterials, including plasmonic metamaterials, is emerging as the next frontier in catalysis research. With new optical behaviors that can be achieved by sub‐wavelength structures, in either periodic or semi‐periodic arrangements, metamaterials can overcome some of the limitations of conventional plasmonic catalysis. This review lays out the results of various metamaterial catalysis demonstrations associated with broadband optical absorption, thermal engineering, anapole resonances and bound in continuum states. This work also discusses emerging metamaterial technologies that can be incorporated into catalysis, such as magnetic concentrators, 2D material‐integrated metamaterial hybrids and colloidal metamaterials. In order for metamaterials to be economically viable, some of the methods to fabricate metamaterial structures on planar surfaces are also discussed. With these unique unnatural advantages and an on‐going drive to lower fabrication costs, electro‐magnetically driven metamaterials can be a promising approach to enabling efficient catalysis toward green fuel production.

Published: December 2024

AbstractThe demand for temperature‐robust electromagnetic wave (EMW) absorption materials is escalating due to the varying operational temperatures of electronic devices, which can easily soar up to 100 °C, significantly affecting EMW interference management. Traditional absorbers face performance degradation across broad temperature ranges due to alterations in electronic mobility and material impedance. This study presented a novel approach by integrating semiconductor metal–organic frameworks (SC‐MOFs) with paraffin wax (PW), leveraging the precise control of interlayer spacing in SC‐MOFs for electron mobility regulation and the introduction of paraffin wax for temperature‐inert electromagnetic properties. This synergistic strategy enhanced dielectric properties and impedance matching across temperature ranges from ambient to 100 °C. A metamaterial shell layer, designed through finite element simulation and fabricated by 3D printing, encapsulated the composite, resulting in a broadband metamaterial absorber with an 11.81 GHz effective absorption bandwidth and a nearly unchanged absorption peak position across 25–100 °C. This temperature‐robust metamaterial absorber paves the way for advanced EMW management materials capable of operating reliably in extreme temperature environments.

AbstractThe study presents a multi‐functional and semiconductor polymer poly[bis(3‐hexylthiophen‐2‐yl)thieno[3,4‐c]pyrrole‐4,6‐dione] (PBDTTPD) doping strategy that significantly enhanced the performance of the two‐terminal all‐perovskite tandem perovskite solar cells (T‐PSCs). An optimized power conversion efficiency (PCE) of 26.87% has been achieved. The incorporation of PBDTTPD into the wide bandgap (WBG) perovskite layer evidently improved its crystallinity and enhanced the top‐cell's PCE to 18.49%. After 2880 h dark storage in nitrogen, the TPSC retained 87.4% of initial PCE, which demonstrates the device's stability. On flexible polyethylene‐naphthalate (PEN) substrate, the TPSC achieved an enhanced champion PCE of 22.96%, and significantly advanced anti‐bending ability. The TPSC's enhanced performance is ascribed to the strong coordinate‐bonding between the S/N/O passivation sites in PBDTTPD, and the Pb2+ defects in the WBG perovskite layer's grain boundaries. Optoelectronic simulations demonstrated a 23%‐24% theoretical PCE limit for the WBG single‐junction PSCs with ≈1.8 eV bandgap. To boost the PCE of next‐generation TPSCs, it is crucial to further mitigate both the bulk and the surface recombination.

Published: December 2024

AbstractWater energy‐converting techniques that focus on interfacial charge separation and transfer have aroused significant attention. However, the water‐repelling nature leads to a less dense liquid layer and a sharp gradient of liquid velocity, which limits its output performance. Here, a water sliding generator (WSG) based on a smooth liquid‐like/semiconductor surface (SLSS) is developed that harnesses the full advantage of liquid sliding friction. The prepared SLSS not only retained the slippery surface's close contact with liquid droplets and the characteristic of sliding without residue but also exhibited an enhanced friction effect on the low‐friction surface. The smooth liquid‐like/semiconductor surface water sliding generator (SLSS‐WSG) exerts outstanding liquid sliding friction energy harvesting with high output (≈16 V and ≈60 µA) demonstrated, capability in series connection, dual operation of power generation and self‐cleaning effect, and high physical and chemical stability (continuous current scour and sun exposure). The prepared surface can be integrated with photovoltaic panels, enabling them to generate electricity from water‐sliding energy during rainy days, compensating for the reduced output of photovoltaic panels during overcast and rainy weather. Furthermore, it allows for energy collection even during rainy nights. The prepared surface can be potentially applied in various fields, showing great potential for the development of water‐based clean energy.

AbstractAqueous zinc‐ion batteries (AZIBs) stand out among many energy storage systems due to their many merits, and it's expected to become an alternative to the prevailing alkali metal ion batteries. Nevertheless, the cumbersome manufacturing process and the high cost of conventional separators make them unfavorable for large‐scale applications. Herein, inspired by the unique nature of cellulose and ZrO2, a Janus cellulose fiber (CF)/polyvinyl alcohol (PVA)/ZrO2 separator is prepared via the vacuum filtration method. The interwoven cellulose fibers offer robust mechanical strength, which prevents dendrites from penetrating through the separator, while ZrO2 nanoparticles with Maxwell‐Wagner effect regulate electric field and effectively promote uniform nucleation. Density functional theory (DFT) reveal CF/PVA/ZrO2 separator's ability to manipulate Zn2+ deposition orientation to Zn (002), resulting in a dendrite‐free, compact, and flat anode. Consequently, the obtained Zn||Zn symmetric cell exhibits superior electrochemical performance, able to operate at 1 mA cm−2 for more than 1500 h and 6 mA cm−2 for 400 h. In addition, CF/PVA/ZrO2 separator outperforms the commercially available glass fiber (GF) separator and CF separator when assembled into full cells using either polyaniline (PANI)@carbon nanotube (CNT) or MnO2@CNT as cathode material. This work serves as a reference for the subsequent research in high performance AZIBs.
Substrate‐Mediated Growth of Au Nanowires Under Weak CTAB Control and Rapid Au Deposition

Published: December 2024

AbstractThe selective Au deposition at the Au‐substrate interface is known to give ultrathin Au nanowires and the synthesis usually employs strong thiol‐based ligands. It is shown that, by increasing the rate of Au deposition, weak cetyltrimethylammonium bromide (CTAB) can be made to behave like a strong ligand, so that it induces Active Surface Growth and gives Au nanowires. The ligand strength also depends on the packing interactions in the ligand layer, in the order of C14TAB, C16TAB, and C18TAB. The substrate‐mediated growth under weak CTAB control is different in many ways from the previous studies, in terms of the huge imbalance in the inter‐particle competition among the active sites, and the formation of nanosheets/nanobelts in defiance of Rayleigh instability of the active sites. With a small amount of chiral thiol‐based ligand (glutathione), the strengthened control by mixed ligands gives orderly bifurcated nanowires, with a clear‐cut transition from the initial nanosheets/nanobelts.
Monetarism and Monetary Policy
Authors: Hetzel Robert L. 
Published: December 2024

AbstractStarting in the 1960s, Milton Friedman defined the monetarist‐Keynesian debate. His greatest victory occurred by the end of the 1970s when he argued that the Federal Reserve System, not corporations and unions with market power, was responsible for inflation. However, monetarism retreated in the early 1980s when high rates of growth of money failed to predict inflation. This paper re‐exposits the quantity theory of money and monetarism in an attempt to again make relevant Friedman's arguments for a rules‐based monetary policy and for an understanding of how in actual practice central banks control inflation assuming inflation is a monetary phenomenon.

Published: December 2024

ABSTRACTThe purpose of this paper is to analyse the factors that influence the low usage of technology orders in Brazil. A systematic literature review was conducted to analyse the theoretical aspects and findings from case studies related to the challenges of implementing this process. The information obtained at this stage enabled a comparison to be made between the potential of technology orders and the opportunities for improvement observed in the national innovation system. The study helped to develop an understanding of the multidimensional nature of technology orders, which connects achieving results with the necessity of implementing appropriate methods and approaches.

AbstractGenomic selection can enhance the rate of genetic gain of cane and sucrose yield in sugarcane (Saccharum L.), an important industrial crop worldwide. We assessed the predictive ability (PA) for six traits, such as theoretical recoverable sugar (TRS), number of stalks (NS), stalk weight (SW), cane yield (CY), sugar yield (SY), and fiber content (Fiber) using 20,451 single nucleotide polymorphisms (SNPs) with 22 statistical models based on the genomic estimated breeding values of 567 genotypes within and across five stages of the Louisiana sugarcane breeding program. TRS and SW with high heritability showed higher PA compared to other traits, while NS had the lowest. Machine learning (ML) methods, such as random forest and support vector machine (SVM), outperformed others in predicting traits with low heritability. ML methods predicted TRS and SY with the highest accuracy in cross‐stage predictions, while Bayesian models predicted NS and CY with the highest accuracy. Extended genomic best linear unbiased prediction models accounting for dominance and epistasis effects showed a slight improvement in PA for a few traits. When both NS and TRS, which can be available as early as stage 2, were considered in a multi‐trait selection model, the PA for SY in stage 5 could increase up to 0.66 compared to 0.30 with a single‐trait model. Marker density assessment suggested 9091 SNPs were sufficient for optimal PA of all traits. The study demonstrated the potential of using historical data to devise genomic prediction strategies for clonal selection early in sugarcane breeding programs.

Published: December 2024

AbstractOne Health is increasingly recognized for its value in addressing emerging infectious disease threats. In Bangladesh, the integration of One Health approaches into outbreak investigation and response can be traced back to the advent of outbreaks of Nipah and avian influenza viruses. Through accounts from epidemiological, anthropological, ecological, and animal health investigations, this chapter narrates a case study of partnership among the government, development partners, and research organizations in Nipah virus outbreak management. It depicts how persuadable, collaborative and problem-solving leadership, cooperative approaches, common goals and mutual support could result in strong partnerships among different individuals and organizations towards building a One Health platform to achieve common goals.
Addressing Sexual and HIV-Related Stigma in Haiti: Need for Societal Engagement
Authors: Dunbar Willy , Coppieters Yves 
Published: December 2024

AbstractAs the world has entered the fourth decade of the AIDS epidemic, Men who have sex with men (MSM) continue to be disproportionately affected by HIV and victims of stigma, prejudice, and discrimination in the Caribbean and Haiti. Using a mixed-methods realist design, we have engaged with MSM communities, healthcare providers, policymakers, and members of civil society to analyze the impact of stigma on the linkages across the continuum of HIV services through engagement, linkage, and retention. Findings showed that from the social construction of heteronormativity to Christian religious and political influences, several factors lie behind sexual and HIV-related stigma, resulting in loss to follow-up and failure to realize the health benefits of proper treatment fully. However, societal engagement and partnerships, multi-level and contextual-based interventions can produce stigma mitigation through personal, health systems’ and contextual mechanisms for better engagement, adherence, and retention in healthcare.

Ethical Challenges in Global Health Research
Authors: Waechter Randall , Coomansingh Kareem , Macpherson Cheryl , Sarma Sameera 
Published: December 2024

AbstractUnderstanding global health ethics requires insight into factors that influence inequalities in global health such as economic disparities, extreme poverty, limits on human rights, political oppression, and unequal distribution of research funding. We review some ethical issues related to global health, focusing on global infectious disease research. Significant ethical concerns include inequities and disparities in national and institutional capacity to conduct global health research on infectious diseases because these can influence the extent to which low-resource countries benefit from the research. Research funding for global health or infectious disease often comes from the governments and institutions of developed countries. It is allocated based on their institutional priorities, which may not align with those of the developing country. When they do align, developing countries may lack the necessary research, manufacturing, and logistical capacity to discover, produce, and distribute medicines and/or vaccines for infectious diseases within their countries. Research ethics guidelines evolve iteratively to help global health practitioners and researchers navigate concerns involving global health and infectious disease. There is an ongoing need for legal and regulatory frameworks, support for research capacity building—including ethics capacity, and systems to audit the impacts of capacity-building programs. While partnerships are essential to carrying out global health research, inequities between high- and low-resource countries drive ethical challenges in global health and infectious disease work. Recognizing and mitigating these inequities is a core challenge in global health research ethics supported by wider efforts toward decolonization.

AbstractThe late René Dubos, a microbiologist and an ecological philosopher, famously coined the phrase, “Think global, act local.” This phrase presents a framework for how we might envision a new direction in education on pathogens across the globe. Infectious diseases can be considered at a global scale, as demonstrated by the recent COVID-19 pandemic, and also at the community scale, as is the case for endemic liver fluke disease in Southeast Asia. While the 30,000 foot view can help us to understand some aspects of a given pathogen and disease, it is critical that we shift our framework, such that local factors affecting disease burden are considered and relevant education is provided to the affected communities. Traditional training in microbiology has focused on knowing the pathogen. To again quote Dubos, “the etiology of disease cannot be entirely explained by the etiology of infection.” If we accept this thesis, then future training in infectious diseases must also encompass knowledge of the environmental and social determinants of health. In this chapter, we will provide a brief historical framework regarding education and research in the field of Tropical Medicine. We will then offer perspectives from the field for contextualizing the current state of training. Finally, we will conclude with ideas on how to create more holistic educational pathways that build interdisciplinary teams able to tackle both infectious disease research and improved wellbeing of affected communities.

Published: December 2024

AbstractThe field of global health has increasingly captured international attention in recent years. The spread of infectious diseases across international borders has sparked significant public attention as well as interest among healthcare workers, researchers, and educators. While the field provides a wide range of exciting opportunities, its historical roots in colonialism and saviorism remain in our current approaches to training and implementation. This chapter presents an overview of the challenges faced in global health training from the perspective of current and recently graduated trainees. Key issues include the gender disparity in leadership positions and insufficient efforts to improve the diversity, inclusion, and retention of minoritized trainees. We also address the growing calls to decolonize global health training and curriculum, examine the role that medicine plays in perpetuating these practices, and discuss how training costs hinder people from low- to middle-income countries and diverse socio-cultural backgrounds from advancing in the field of global health. We highlight our collective experiences in global health research and clinical training to emphasize the need for a new vision and approach to training future global health leaders. Furthermore, we aim to offer constructive criticism of the existing institutional system frameworks, and most importantly, we aim to align ourselves with the voices of those who have fiercely advocated for a more inclusive field.

AbstractInfectious disease research requires expertise from multiple diverse backgrounds. In Papua New Guinea (PNG), relationships are an integral part of the culture, both historically and today, and play a critical role in conducting infectious disease research activities across the country. Research efforts on vector-borne diseases (VBDs), such as malaria and dengue, run parallel to rigorous implementation research to reduce the burden of other neglected tropical diseases and combat growing anti-microbial resistance in the country. This chapter will highlight the history of collaborative research in Papua New Guinea and specifically, how the partnership-based approach to implementation research has been adopted to conduct infectious disease research at different levels of the health system. In PNG, genuine trust-based relationships have been established over time by incorporating a set of guiding principles into daily practice and focusing on principles such as authenticity, courage, equality, equity, mutual benefit, and transparency throughout the research cycle. This chapter showcases key learnings across multiple and interconnected levels of the health system. It also sheds light on nuanced approaches to partnerships which harness local knowledge and empower champions to enable meaningful research and systemic change.
