Methods for substituting onsite ambient ultraviolet radiation measurements for personal exposure studies

Photochemistry and Photobiology, EarlyView.
Three methods for substituting on‐site ambient ultraviolet radiation measurements for personal exposure measurements were investigated. Assuming spatial persistency of measurements from high‐grade instruments delivers lowest uncertainties up to distances of 82 km.

Ultra‐Broadband Optical Characterization of TiO2 Nanotube Arrays Revealing Annealing‐Tunable THz Absorption

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
Lithography‐free spaced TiO2 NT arrays unlock tunable broadband absorption from THz to UV. By harnessing annealing‐driven phase transitions, strong phonon–polariton resonances emerge in the 1.4–3.6 THz range, whereas high absorptance persists beyond 10 THz.

Review of Amorphous Gallium Oxide: From Material Synthesis to Device Applications

physica status solidi (a), Volume 223, Issue 15, 5 August 2026.
Amorphous gallium oxide (a‐Ga2O3) is reviewed as a promising ultra‐wide‐bandgap material for solar‐blind UV photodetectors. The influence of structural disorder, defect states, and trap‐assisted transport on optical and electronic performance is examined.

Compact Fourier‐Transform Spectrometer on Thin‐Film Lithium Niobate via Mode‐Circulating Modulation

Advanced Photonics Research, Volume 7, Issue 8, August 2026.
Schematic diagram of the proposed compact on‐chip Fourier‐transform spectrometer on thin‐film lithium niobate that exploits mode‐circulating electro‐optic modulation, in which guided light is sequentially converted among multiple spatial modes to accumulate multiple phase modulation events within a single physical modulation arm.

An Instrument for Isomer‐Specific Action Spectroscopy of Charged Clusters: Electronic Spectra of C 14 + and Ca@C 60 +

Chemistry–Methods, Volume 6, Issue 8, August 2026.
Disentangling spectral congestion of a mixture of isomers in gas‐phase spectroscopy is critical. We present an instrument combining ion mobility, mass spectrometry, and spectroscopy in a cryogenic 3D Paul trap to investigate the isomer‐specific charged clusters and illustrate its performance with the electronic spectra of C14+ and Ca@C60+. Interpreting

Designing chiral organic small molecules for circularly polarized light detection via group theory

InfoMat, Volume 8, Issue 8, August 2026.
The chiral point group determines the arrangement of the μ‐m of chiral organic small molecules, thereby influencing their chiral photoelectric properties. In particular, chiral molecules with the D2 point group can effectively align the μ‐m to be either 0° or 180°, an effective strategy for high‐performance circularly polarized light photodetectors ...

An Ultrafast Time Resolved Infrared and Computational Study of the Photochemistry of Ethyl 2‐Diazo‐3,3,3‐Trifluoropropanoate (CF3CN2CO2Et)

Journal of Physical Organic Chemistry, Volume 39, Issue 8, August 2026.
The photochemistry of ethyl 2‐diazo‐3,3,3‐trifluoropropanoate shows that its excited singlet state undergoes internal conversion, carbene formation, and diazirine formation. The resulting singlet carbene reacts through solvent‐dependent pathways, forming ylides in methanol and acetonitrile or a C–Cl insertion product in chloroform.

Electronic and Structural Effects in Porphyrin Metal–Organic Framework Sensitizers for Solid‐State Dye‐Sensitized Solar Cells

ChemPhysChem, Volume 27, Issue 14, 29 July 2026.
Porphyrin metal–organic frameworks (PMOFs) offer structurally ordered and compositionally tunable platforms for sensitized photovoltaics. Titanium‐ and indium‐based PMOFs, together with a tin‐doped indium analog, were investigated as photosensitizers in solid‐state dye‐sensitized solar cells (ssDSSCs). Electrochemical and optical measurements confirmed
