Silicon nanowires (SiNWs) have demonstrated great potential for energy storage due to their exceptional electrical conductivity, large surface area, and wide compositional range. Metal-assisted chemical etching (MACE) is a widely used top-down technique for fabricating silicon micro/nanostructures. SiNWs fabricated by MACE exhibit significant surface areas and diverse surface chemistry.

Metal-oxide-based gas sensors are extensively utilized across various domains due to their cost-effectiveness, facile fabrication, and compatibility with microelectronic technologies. The copper (Cu)-based multifunctional polymer-enhanced sensor (CuMPES) represents a notably tailored design for non-invasive environmental monitoring, particularly for detecting diverse gases with a low concentration. In this investigation, the Cu-CuO/PEDOT nanocomposite was synthesized via a straightforward chemical oxidation and vapor-phase polymerization.

Article Synopsis
  • Researchers developed a new type of sodium-ion solid-state electrolyte called NaPSCl, which is chlorine-rich and has shown significant improvements in ionic conductivity compared to previous versions, reaching a peak conductivity of 1.2 × 10 S/cm at 25 °C.
  • The study found that the increased chlorine content enhanced both ionic conductivity and electrochemical stability while lowering activation energy, making the NaPSCl composite a pure ionic conductor without electronic conductivity.
  • Testing in a lab-scale all-solid-state sodium battery demonstrated stable performance, showing the potential of NaPSCl as an effective electrolyte and highlighting an anion-modulation strategy for future solid-state electrolyte development.

As supercapacitor (SC) technology continues to evolve, there is a growing need for electrode materials with high energy/power densities and cycling stability. However, research and development of electrode materials with such characteristics is essential for commercialization the SC. To meet this demand, the development of superior electrode materials has become an increasingly critical step.

A high capacitance and widened voltage frames for an aqueous supercapacitor system are challenging to realize simultaneously in an aqueous medium. The severe water splitting seriously restricts the narrow voltage of the aqueous electrolyte beyond 2 V. To overcome this limitation, herein, we proposed the facile wet-chemical synthesis of a new CuSe-TiO-GO ternary nanocomposite for hybrid supercapacitors, thus boosting the specific energy up to some maximum extent.

The interaction between cathode and anode materials is critical for developing a high-performance asymmetric supercapacitor (SC). Significant advances have been made for cathode materials, while the anode is comparatively less explored for SC applications. Herein, we proposed a high-performance binder-free anode material composed of two-dimensional ZnFeO nanoflakes supported on carbon cloth (ZFO-NF@CC).

Water is essential for life, agriculture, and industrialization; however, a rapid increase in population is constantly causing water scarcity and pollution in Pakistan. Mining activities produce the potential toxic element (PTE) accumulation, which lead to unnatural enrichment, ecological pollution, and environmental degradation. The ecological resources impeded by the PTEs cause serious abnormalities in the population through dermal contact, inhalation, and digestion.

Difluoroethane is the active ingredient in various computer cleaners and is increasingly abused by teenagers due to its ease of access, quick onset of euphoric effects, and lack of detectability on current urine drug screens. The substance has detrimental effects on various organ systems; however, its effects on the kidneys remain largely unreported. The following case report adds new information to the developing topic of acute kidney injury in patients abusing difluoroethane inhalants.

Introduction: Transposed basilic vein arteriovenous fistulas suffer from stenosis at their basilic angle of transposition (BAT). This lesion exhibits frequent recurrence after angioplasty. The primary goal of this study was to determine the effect of stent-graft placement on BAT lesion- and access-patency.

Arteriovenous grafts (AVGs) suffer from high thrombosis rates. It is not known whether placement of stent grafts at the venous anastomosis (VA) of thrombosed AVGs would impact future thrombosis. This is a retrospective study evaluating a group of AVGs that underwent endovascular thrombectomy with placement of a stent graft at their VA.

Bread wheat (Triticum aestivum L.) germplasm consisting of 45 genotypes were clustered phenotypically using ten morphological traits and Area Under Disease Progress Curve (AUDPC) as measure of stripe rust resistance. The clustering was ratified by using twenty three molecular markers (SSR, EST and STS) linked to stripe rust (Puccinia striiformis f.

Daclizumab can decrease the incidence of acute rejection (AR) in renal transplant (RTx) recipients. In this prospective study, 52 RTx patients were divided into two groups according to the dose of daclizumab: 1 mg/kg on day 0 and every 14 days for five doses (group 1, n = 30) or a truncated regimen of 2 mg/kg on day 0 and on the day of discharge (group 2, n = 22). The following variables were recorded: demographics; delayed graft function; AR at 3, 6, and 12 months; time to AR; chronic allograft nephropathy (CAN); and serum creatinine.
