Semiconducting transition metal dichalcogenides (TMDs) have attracted significant attention for their potential to develop high-performance, energy-efficient, and nanoscale electronic devices. Despite notable advancements in scaling down the gate and channel length of TMD field-effect transistors (FETs), the fabrication of sub-30 nm narrow channels and devices with atomic-scale edge control still poses challenges. Here, we demonstrate a crystallography-controlled nanostructuring technique to fabricate ultranarrow tungsten disulfide (WS) nanoribbons as small as sub-10 nm in width.

Two-dimensional (2D) transition metal dichalcogenides (TMDs) have received significant interest for use in tunnel field-effect transistors (TFETs) due to their ultrathin layers and tunable band gap features. In this study, we used density functional theory (DFT) to investigate the electronic properties of six TMD heterostructures, namely, MoSe/HfS, MoTe/ZrS, MoTe/HfS, WSe/HfS, WTe/ZrS, and WTe/HfS, focusing on variations in band alignments. We demonstrate that WTe/ZrS and WTe/HfS have the smallest band gaps (close to 0 or broken) from the considered set.

Potentially toxic elements (PTEs) and microplastics (MPs) in the atmosphere raise widespread apprehension due to their association with the ecosystem and public health. The accumulation of airborne MPs and PTEs was analyzed in leaves, and the Pollution Index (PI) was calculated along an industrial, residential, and rural gradient in Bangladesh. Only polyethylene terephthalate (PET) was found in the highest concentration in industrial areas compared to other areas.

Despite the significant growth in Sonali chicken production across Bangladesh, inadequate disease surveillance and control measures along with indiscriminate antimicrobial use remain major challenges to the sector. In this study, we evaluated the disease burden and antimicrobial prescription patterns of Sonali chickens in Bangladesh using a web-based data recording system from 2020 to 2021 and analyzed 1690 cases. The diagnoses recorded in the system were presumptive, as they were based on clinico-epidemiological history, clinical signs, and gross necropsy findings noted by registered veterinarians.

Evaluating fish habitat suitability (FHS) is of utmost importance in the present times, as rising pollution and ecological stress have led to the deterioration of their habitat and population. The present study has evaluated ecological water quality using the comprehensive pollution index (CPI), eutrophication index (EI), and organic pollution index (OPI). Fish community structure has been assessed based on tropic level score (TLC) and habitat orientation score (HOS).

This study investigates the use of various industrial waste materials-silica fume (SF), cement kiln dust (CKD), calcium carbide residue (CCR), rice husk ash (RHA), and ground granulated blast furnace slag (GGBS)-as eco-friendly stabilizers for expansive clay soil (ECS). Laboratory tests were conducted to assess the impact of different proportions (3 %, 6 %, and 9 %) of these additives on the soil's physical, mechanical, and microstructural properties. Results indicated that the inclusion of industrial waste significantly improved the soil's behavior, with notable reductions in liquid limit (up to 37.

The disruption of health service delivery during public health emergencies, like Ebola and COVID-19, due to hesitancy among healthcare workers (HCWs) is well-documented. While previous studies have identified motivating factors for HCWs, accommodating all is often unfeasible due to resource limitations. Thus, identifying precise preferences is crucial from a policy standpoint.

The discovery of ferroelectricity in hafnia based thin films has catalyzed significant research focused on understanding the ferroelectric property origins and means to increase stability of the ferroelectric phase. Prior studies have revealed that biaxial tensile stress via an electrode "capping effect" is a suspected ferroelectric phase stabilization mechanism. This effect is commonly reported to stem from a coefficient of thermal expansion (CTE) incongruency between the hafnia and top electrode.

Unlabelled: Difficulties exist in obtaining full-length, correctly folded, and soluble papain or papain-like proteases that necessitate the exploration of alternative strategies. This study describes the development of an strain capable of producing soluble papain without the need for complex and time-consuming refolding steps. To enhance the production of soluble papain, engineered T7 promoters and a recombinant papain translationally fused with varying tags were constructed.

This article provides a dataset for line × tester analysis in the F1 generation of summer tomatoes using open-source R statistical software and the 'agricolae' package. The dataset includes seven inbred lines as female parents (L) and two testers as male parents (T) with diverse genetic bases and heat tolerance qualities. Fourteen cross combinations were produced through L × T (7 × 2) mating design, involving hybridization between lines () and testers () in a one-to-one fashion.

Despite professional skills being part of the Day One Competences published by national as well as international accreditation bodies, veterinary schools in Bangladesh have limited associated teaching within their curricula. Therefore, our study aimed to identify the most important professional skills for veterinarians in Bangladesh through local consultation to inform future initiatives to change the curriculum. Eleven focus groups were conducted with 45 stakeholders who included veterinarians who supervise students on workplacements, faculty, recent graduates, final year students, and clients.

Despite extensive efforts to develop γ-lactamization reactions for pyrrolidinone synthesis using either cyclometallation, C-H insertion, or radical C-H abstraction strategies, γ-lactamization reactions of aliphatic amides using practical catalysts and common protecting groups remain extremely rare. Herein we report copper-catalyzed γ-C(sp)-H lactamization and iminolactonization of tosyl-protected aliphatic amides using inexpensive Selectfluor as the sole oxidant. A switchable selectivity of γ-lactams or γ-iminolactones can be obtained by using two different sets of reaction conditions.

Article Synopsis
  • The study examines how thermal conductivity in metallic nanostructures changes as their size approaches the mean free path of electrons, revealing decreased conductivity due to increased scattering.
  • Matthiessen's rule, used for assessing electron scattering rates, was experimentally validated as it applies to thin copper films of varying thicknesses and structures.
  • The research finds that while the electron-phonon coupling factor is consistent regardless of thickness, electronic scattering rates rise as film thickness decreases, providing insights for improving thermal management in future electronics.
