Even though efficient near-infrared (NIR) detection is critical for numerous applications, state-of-the-art NIR detectors either suffer from limited capability of detecting incoming photons, i.e., have poor spectral responsivity, or are made of expensive group III-V non-CMOS compatible materials.

The demand for broadband, room-temperature infrared, and terahertz (THz) detectors is rapidly increasing owing to crucial applications in telecommunications, security screening, nondestructive testing, and medical diagnostics. Current photodetectors face significant challenges, including high intrinsic dark currents and the necessity for cryogenic cooling, which limit their effectiveness in detecting low-energy photons. Here, we introduce a high-performance ultrabroadband photodetector operating at room temperature based on two-dimensional black arsenene (b-As) nanosheets.

Circular dichroism mapping (CDM) method was introduced by utilizing the highly collimated light beam of synchrotron radiation (SR) available at Diamond Light Source B23 beamline for scanning the thin films of the N phase. We apply SR-CDM to two achiral dimeric materials exhibiting the N phase: symmetric DTC5C9 and dissymmetric DTC5C9CB. The SR-CDM measurements directly capture the chiral information in the local N domains, providing the ultimate complement to the theoretical predictions of the helical structures: the spontaneous symmetry breaking in N phase is ambidextrous.

Anthropogenic climate change will have a negative impact on worldwide well-being over and above the direct consequences of rising average temperatures. But anthropogenic heat (AH) relationship with childhood attention deficit hyperactivity disorder (ADHD) is unknown. To assess the relationship with AH exposure and childhood ADHD symptoms in the context of global climate change, this study was conducted in a cross-sectional survey from April 2012 to May 2018 in the northeastern, northwestern, and southern regions of China, with a total enrollment of 179,846 children aged 6-18 years.

Monitoring the seasonal and diurnal variations in headwater stream metabolic regimes can provide critical information for understanding how ecosystems will respond to future environmental changes. In East Fork Creek, a headwater stream in middle Tennessee, week-long field campaigns were set up each month from May 2022 to May 2023 to collect stream metabolism estimators. In a more extensive field campaign from July 2-5 in 2022, diel signals were observed for temperature, pH, turbidity, and concentrations of Ca, Mg, K, Se, Fe, Ba, chloride, nitrate, DIC, DO, DOC, and total algae.
