Advances in Floating Solar Desalination Systems

Water and Environment Journal, EarlyView.
This review critically classifies floating solar desalination systems into five main categories and compares their thermal performance, productivity and technological limitations. Membrane‐based and multieffect systems showed the highest efficiencies, while traditional designs remain limited by heat losses and scaling.

Cryogen‐Aided Chromatographic Purification of Millimole Quantities of Methane for Spectroscopic Clumped Isotope Analysis

Rapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Quantum cascade laser absorption spectroscopy (QCLAS) is a fast and reliable method for analyzing the bulk (𝛿13C‐CH4, 𝛿D‐CH4) and clumped isotopic (∆13CH3D and ∆12CH2D2) composition of methane. However, precise measurements of ∆12CH2D2 require 0.5 to 1.8 mmol of purified methane (equivalent to 15 to 40 mL at STP).

Theoretical and Experimental Study of Positive-Pressure Condensation Heat and Mass Transfer Processes in Bent-Tube Heat Exchangers

Buildings
Condensation dehumidification is currently the mainstream means of dehumidification, and the idea is to precipitate moisture by cooling the air below the dew point temperature; however, this process requires the use of a chiller to provide a low ...
