The UN Sustainable Development Goals (SDGs) are becoming a crucial mechanism for coordinating governments’ efforts to address global challenges. However, their implementation by managers is challenging. In this article, we offer an overview of the pros and cons SDGs as mechanisms multinationals help contribute sustainable development. On pro side, comprehensive actionable. con they vague, complex may lend themselves “rainbow-washing.” We provide suggestions them respond these challenges...
In this study, we propose the fabrication of a photodetector based on heterostructure p-type Si and n-type MoS2. Mechanically exfoliated MoS2 flakes are transferred onto layer; resulting Si–MoS2 p–n photodiode shows excellent performance with responsivity (R) detectivity (D*) 76.1 A/W 1012 Jones, respectively. addition, effect thickness depletion layer heterojunction is investigated using model; obtained results, optimize photoresponse device by varying thickness. Furthermore, low-frequency...
This Special Issue explores the vital connection between business and public health, highlighting their interdependence in addressing today’s global challenges. First, we demonstrate how firms are both contributors to recipients of health outcomes. Second, examine complexities faces defining its responsibilities, particularly when navigating diverse often ambiguous stakeholders, such as communities. Third, emphasize importance interdisciplinary research multifaceted challenges at...
Negative photoconductivity (NPC), a reduction in under light illumination, could provide low power consumption and high-speed frequency response. The NPC has been generally observed low-dimensional materials, which can be easily affected by the trapping of photocarriers. However, gradual transition between positive (PPC) controlling intensity not reported. In this study, reversible switching PPC is achieved van der Waals heterostructure graphene MoTe2. initially state becomes with increase...
There are only a few insole ground reaction force (GRF) measurement systems for running and jumping because the capacity durability of system were not guaranteed to measure heavy load on foot. We propose insole-type that can up 900N assure GRF during jumping. The proposed was implemented using sensor-embedded flexible shoe including four custom optoelectronic based sensors with high reliability. In order evaluate performance sensor, static loading unloading tests performed compare hysteresis...
In recent years, inflatable actuators have been widely used in wearable suits to assist humans who need help moving their joints. Despite lightweight and simple structure, they long inflation deflation times, which make quick use difficult. To resolve this issue, we propose an wrinkle actuator with fast responses. First, a theoretical model is proposed develop that satisfies the design requirements: desired assistive torque foam factor based on wearability. Second, reduce times by partially...
We investigate the reverse leakage characteristics of InGaN/GaN multiple-quantum-well light-emitting diodes (LEDs) grown on Si (111) substrate by metal-organic chemical vapor deposition. The LED silicon are measured as low ~10 nA at -5 V and -10 μA -15 V. Temperature-dependent current-voltage ( <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">I</i> - xmlns:xlink="http://www.w3.org/1999/xlink">V</i> ) measurements devices reveal that current...
Despite the rapid advances in soft robotic actuation technologies, main energy source that powers most wearable systems remains conventional tethered stationary air compressor greatly limits these systems' applicability. Several portable pneumatic sources have been introduced; however, limited maximum output pressure and flow rate, size weight, large operational noise, potential safety hazards must still be resolved before being applied to current applications. In this study, we propose...

A data-driven approach has recently been investigated for identifying human joint angles by means of soft strain sensors because the corresponding modeling difficulty. However, this commonly incurs a high computational burden due to voluminous amount data required and time-series-oriented network architecture. Moreover, nature makes problem worse inherent nonlinearity hysteresis material. In study, we developed novel wearable sensing brace design measuring multiple degrees freedom (DOF)...
Organic photodetectors (OPDs) show their advantages in flexibility, lightweight, and ultrathin form factors, large area compatibility, low-cost manufacturability, but absorption wavelengths are typically limited to the visible range. Although internal photoemission is a promising platform achieve sub-bandgap photodetection near-infrared (NIR) or mid-IR wavelengths, very few studies have been reported for organic-based Schottky barrier (SBPDs) operable NIR region. In this work, we...
