title: Data-Integrated microbial–enzymatic pathways driving carbon sequestration in plant litter crusts of semi-arid sandy soils

description: Field sampling was conducted in July 2018 and 2019 in degraded sandy soils at litter crust monitoring sites, following the methodology of Cheng et al. (2025). Three representative sites, spaced more than 1000 m apart, were selected in vegetation-free areas (within a one-meter radius). At each site, four treatments were established: bare sandy soil (control), early-successional litter crust (1-3 years), mid-successional litter crust (3-5 years), and late-successional litter crust (5-8 years) (Fig. 1a). Naturally formed litter crusts, consisting mainly of Populus simonii Carr. and other plant litter, persist for several years and typically as discrete patches or belts in low-lying or flat sandy areas. The age of the litter crust was determined in the field based on established morphological characteristics, including litter color and the degree of adhesion between soil and litter (Jia et al. 2018). Sampling was conducted in two consecutive years, providing six replicates per treatment (3 sites × 2 years). For each treatment, three replicate plots (1 m × 1 m) were established at each site, spaced more than 10 m apart. Within each plot, composite soil samples were collected from the 0-10 cm depth using a 5-cm-diameter soil auger. Each composite sample consisted of five sub-samples obtained via the five-point sampling method. All samples were immediately placed in insulated coolers with ice packs and transported to the laboratory on the same day. One portion was stored at -80 ℃ for DNA extraction, another at 4 ℃ for enzyme activity assays, and the remainder was air-dried for physicochemical soil characterization. Prior to analysis, visible plant debris was removed by sieving through a 2-mm sieve.

description: 30-minute Soil Moisture data at 10 cm at CSIS Block-9. Collection of soil volumetric water content data at Jornada LTER Cross-scale Interactions Study (CSIS) blocks, New Mexico, supports the environmental monitoring objectives of the Jornada LTER monitoring program that look at plant-soil water dynamics. Soil volumetric water content is measured at 10 cm depth at 3 locations at each of the 4 plots per block. The locations in each plot are under bare soil, under perennial grass, and under shrub. Volumetric water content, bulk electrical conductivity, soil temperature, and bulk dielectric permittivity are recorded every 30 minutes at an automated meteorological station installed at Jornada LTER CSIS Block-9 site. This is an ONGOING dataset.

title: Development of a two-board potentiostat device for real-time detection of cadmium ion in solution

description: Cadmium is classified as a non-essential heavy metal element as it is harmful to human health even in a trace amount. Despite the implementation of guidelines and regulations on cadmium handling, unfortunately, mortality cases among wild animals due to cadmium poisoning still occur. To effectively investigate the sources of cadmium contaminants in the environment, it is suggested to establish real-time monitoring across the area. Thus, the aim is to design and develop a potentiostat device (HMstat) with the capability to perform a square wave anodic stripping voltammetry (SWASV) method for real-time monitoring of cadmium ion detection. The design and development of the HMstat are realized by using a two-board type potentiostat which is implemented through-hole technology as an analog component and the myRIO platform as a digital component. The capability of HMstat working under constant, ramp, and SWV signals has suggested that the HMstat has a high potential to perform the SWASV method.

The design files included here are:
Constant_applied_potential: containing LabVIEW file of constant V_ap signal generation

Utilizing the DUAL Nominator mechanism, we establish a mathematically rigorous model incorporating a 51/49 frictional balance, a finite scaling threshold, and a 90-degree rotational transformation to regulate quantum oscillations. Our high-precision computational simulations demonstrate self-regulating energy stability within the vacuum field, suggesting <b>profound connections</b> between prime sequences, gravitational wave structures, and space-time geometry.
