The Role of Current Mismatch on Reverse‐Bias Stability of Monolithic Perovskite/Silicon Tandem Solar Cells

open access: yesEcoEnergy, Volume 4, Issue 4, August 2026.
Reverse‐bias stability in monolithic perovskite/silicon tandem solar cells requires a silicon–current‐limited regime. When the perovskite current exceeds the silicon current, the reverse voltage is mainly borne by the silicon cell, reducing perovskite stress.

Transient Conjugate MHD Flow With Variable Thermal Conductivity: A CFD to ANN Study

open access: yesEngineering Reports, Volume 8, Issue 8, August 2026.
A star‐shaped obstacle inside a hexagonal cavity alters fluid flow and heat transfer under magnetic fields. Simulations and ANN predictions reveal that magnetic strength and material properties control cooling efficiency, supporting smarter designs for real‐time thermal management.

Quantifying Multidimensional Effects in Linear Site Response Using 1D and 2D Simulations of Sedimentary Basins in Wellington, New Zealand

open access: yesEarthquake Spectra, Volume 42, Issue 3, August 2026.
This study quantifies the influence of multidimensional effects on site response in the Wellington region of New Zealand by comparing results from different simulation approaches. Response‐spectral amplification functions from 1D and 2D site response analyses are compared to quantify the magnitude and spatial distribution of multidimensional effects ...

Inter‐Theta‐Gram Spectroscopy: A General Super‐Spectral‐Resolution Scattering Method Demonstrated on Diamond

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 8, Page 1359-1366, August 2026.
Inter‐Theta‐Gram spectroscopy enables super‐spectral‐resolution Raman analysis by jointly reconstructing the excitation laser line and Raman peak during an etalon angle scan, yielding internally referenced Raman shifts. Demonstrated on lab‐grown versus natural diamond, it resolves 0.1–0.2 cm−1 Raman‐shift offsets that are invisible in conventional ...

A physics primer on photon‐counting detectors in CT: Physics, signal formation, and performance

open access: yesMedical Physics, Volume 53, Issue 8, August 2026.
Abstract Photon‐counting detector CT (PCD‐CT) is moving from laboratory development to clinical deployment. However, its threshold‐bin data arise from a tightly coupled detector–readout chain that can be difficult to understand as a whole. These data are not a direct readout of photon energy, but the outcome of a sequence of physical and electronic ...

Enhancement of the WS2 A1g Raman Mode in MoS2/WS2 Heterostructures

open access: yesphysica status solidi (b), Volume 263, Issue 8, August 2026.
In van der Waals heterostructures consisting of WS2 and MoS2 monolayers, we find a strong, selective enhancement of the WS2 A1g Raman mode due to interlayer coupling and in‐phase vibration of sulfur atoms in the adjacent MoS2 layer. When combined into heterostructures, transition metal dichalcogenide monolayers enable the exploration of novel physics ...

Accurate Sizing and Resolution of Nominal 200 nm Diameter Polystyrene Nanospheres With Charge Detection Mass Spectrometry

open access: yesSmall, Volume 22, Issue 43, 3 August 2026.
This study highlights the utility of charge detection mass spectrometry (CDMS) as a high‐throughput nanoparticle characterization tool. CDMS measurements of 200 nm polystyrene size standards are within 1% of those derived from transmission electron microscopy (TEM). Notably, a mixture of three ∼200 nm samples is readily resolved by CDMS but not by TEM,
