The intrinsic n-type behavior and unavailability of the appropriate p-type doping method for MoS allows only n-type conduction with depletion mode (D-mode) characteristics and forbids the implementation of p-type field-effect transistors (FETs). The D-mode characteristic results in a high off-current (I) at zero gate bias, which limits the usage of MoS FETs for industry-scale (n-channel metal-oxide semiconductor) NMOS/(complementary metal-oxide semiconductor) CMOS-logic-based applications due to significant power dissipation. Both these issues, i.

Article Synopsis
  • * This study focused on measuring the ice nucleation rate of 2-methyltetrols (2-MT), a component of certain organic aerosols, and found that as the aerosol's viscosity increases, its ice nucleation ability also increases significantly, especially when transitioning from liquid to semisolid states.
  • * A new model based on classical nucleation theory was created to quantify the relationship between viscosity and ice nucleation rate, which can be used in climate models to better represent cir

Wildfires emit solid-state strongly absorptive brown carbon (solid S-BrC, commonly known as tar ball), critical to Earth's radiation budget and climate, but their highly variable light absorption properties are typically not accounted for in climate models. Here, we show that from a Pacific Northwest wildfire, over 90% of particles are solid S-BrC with a mean refractive index of 1.49 + 0.

Article Synopsis
  • - Arabinoxylan, a complex sugar, can be broken down by enzymes like α-l-arabinofuranosidase and xylanase; a new bifunctional enzyme (BoGH43_35) from Bacteroides ovatus has been studied for its ability to degrade these sugars.
  • - The enzyme's structure features a stable 5-bladed β-propeller fold and carbohydrate-binding modules, with molecular dynamics confirming its compactness and stability during simulations.
  • - Binding affinity analysis showed BoGH43_35 has the strongest interaction with arabinose and maintains stability in its complex forms, along with measurements suggesting good solubility and low aggregation in solution.

Background & objectives India has been classified as an intermediate Hepatitis B Virus (HBV) endemic country, and the transmission is believed to mostly occur horizontally. However, community-based data on HBV prevalence among blood donors in India are limited. The burden of Hepatitis B Virus (HBV) is unknown in the asymptomatic blood donor population.
