s‐Orbital Mediated Metavalent Bonding Enables State‐Of‐The‐Art n‐Type AgBiSe2 Thermoelectrics
Advanced Functional Materials, EarlyView.Metavalent bonding (MVB) underpins the exceptional property portfolio of chalcogenides. Typical MVB solids are mainly found in p‐bonded systems. This work reveals that MVB can also be formed with s‐p orbital interactions upon forming a single‐electron σ‐bond, as exemplified in AgBiSe2.

A Study of pressure fluctuation caused by hydraulic jump in stilling basin [PDF]
مهندسی منابع آب, 2018 A stilling basin is one of the energy dissipaters downstream of a spillway. The place of maximum pressure caused by jet impact and the effect of various factors on the amount and location of pressure are important factors in designing of stilling basin ...

Triple basin active solar still
International Journal of Energy Research, 1999 The Runge–Kutta method has been used to solve three coupled differential equations to determine the performance of an active triple basin solar distillation system. Hourly variation of various temperatures and yield have been evaluated alongwith overall thermal efficiency.

Theoretical Criterion for Stability of Free Hydraulic Jump on Adverse Stilling Basins [PDF]
Journal of Hydraulic Structures, 2014 Hydraulic jump on adverse stilling basin is an unstable phenomenon which causes some complexities in controlling of the jump. This paper considers the stability of free hydraulic jump on adverse stilling basins from a theoretical point of view.

Advanced Science, EarlyView.ABSTRACT Precise transgene‐free gene upregulation remains a challenge in crop biotechnology, as conventional enhancers often exceed CRISPR‐mediated knock‐in size constraints and face regulatory hurdles. Here we establish a foundational cross‐species resource of compact transcriptional enhancers developed via STEM‐seq, a high‐throughput screening ...
