The increasing reliance on nuclear energy as a significant low‐carbon power source necessitates effective solutions for managing radioactive emissions. This study introduces a novel application of MXene nanohybrids, specifically silver‐MXene (Ag‐Ti3C2Tx), as an effective sorbent for radioiodine off‐gas capture at an operating temperature of 150 °C. Through comprehensive material characterization, including X‐ray diffraction, scanning and transmission electron microscopies, energy‐dispersive X‐ray spectroscopy, Raman spectroscopy, thermogravimetric analysis, inductively coupled plasma optical emission spectroscopy, and gas sorption analyses, the successful loading of Ag nanoparticles onto Ti3C2Tx is confirmed and the subsequent formation of AgI upon iodine capture. The results demonstrate that Ag‐Ti3C2Tx exhibits superior iodine uptake compared to traditional silver‐based sorbents such as silver mordenite zeolite (AgZ) and silver‐functionalized silica aerogel (AgAero). The Ag‐Ti3C2Tx achieves an iodine loading of 946 mg g−1, significantly outperforming AgZ (131 mg g−1). These findings highlight the potential of Ag‐Ti3C2Tx as a highly efficient, thermally stable sorbent for radioiodine capture, and potentially addressing key limitations of existing materials. Silver‐MXene (Ag‐Ti3C2Tx) nanohybrids effectively captured iodine gas at 150 °C, with Ag nanoparticles loaded onto MXene via silver nitrate reduction. Upon exposure to iodine gas, silver iodide forms, confirming successful adsorption. Ag‐Ti3C2Tx shows superior iodine uptake (946 mg g−1) compared to conventional sorbents, demonstrating its potential as an efficient, thermally stable solution for radioiodine capture.

Silver‐MXene Nanohybrid for Iodine Gas Capture In article 2500011, Michael Naguib and co‐workers report the synthesis of silver‐MXene nanohybrids and demonstrate their use for iodine gas capture at 150 °C. The material achieves an iodine uptake of 946 mg·g−1, outperforming conventional silver‐based sorbents. The formation of thermally stable silver iodide is confirmed, underscoring the potential of MXene hybrids as effective sorbents for radioiodine and nuclear off‐gas capture applications.

Tracing the flow of solid matter during an explosion requires a rugged tag that can be measured by a unique identifiable signature. Silica-covered semiconductor quantum dots (QDs) provide a unique and tunable photoluminescent signature that emits from within a sacrificial outer layer. Five types of silica-covered zinc sulfide QDs were synthesized and covalently bound to commercial luminescent powders. The combination of five dots and five powders enables a matrix of 25 unique tags. The tracers are shown to be tolerant of environments associated with chemical explosives and provides a unique tag to evaluate debris fields.

Non-destructive testing using the technique of thermal wave imagine is a relatively recent innovation still out of define its useful boundaries. As a consequence this approach is still undergoing practical and theoretical development in the areas of; thermal wave detection, measurement techniques and applications.The work described in this thesis covers elements of all the above areas from the development of practical photoacoustic and photo thermal detectors to their use in thermal wave imaging experiments. These tests were performed on a wide range of coating materials (<1mm thick) including metals, polymers and ceramics detecting both changes in coating thickness and delamination’s. Imagine interpretation was significantly aided by swept frequency measurements which acted as an ideal method of detector characterization, sometimes allowing specimen thermal diffusivity to be accurate measured. This was even extended in a few situations to cover a direct comparison between theoretical and observed behavior. Attention was particularly focused on piezoelectric thermal wave detection which proved far more versatile than expected, dominating most of the work.
