Practical applications of small-angle neutron scattering
Recent improvements in beam-line accessibility and technology have led to small-angle neutron scattering (SANS) becoming more frequently applied to materials problems. SANS has been used to study the assembly, dispersion, alignment and mixing of nanoscale condensed matter, as well as to characterise the internal structure of organic thin films, porous ...

Ultra-small-angle neutron scattering with azimuthal asymmetry [PDF]
Small-angle neutron scattering (SANS) measurements from thin sections of rock samples such as shales demand as great a scattering vector range as possible because the pores cover a wide range of sizes. The limitation of the scattering vector range for pinhole SANS requires slit-smeared ultra-SANS (USANS) measurements that need to be converted to ...

This review explores how in situ and operando spectroscopic techniques reveal the real‐time behavior of reticular materials, including MOFs and COFs. These methods track material formation and functionalization, structural changes, defect formation, dynamic responses to external triggers, and catalytic processes.

Monitoring of Bainite Transformation Using in Situ Neutron Scattering
Bainite transformation behavior was monitored using simultaneous measurements of dilatometry and small angle neutron scattering (SANS). The volume fraction of bainitic ferrite was estimated from the SANS intensity, showing good agreement with the results

Liquid Argon Cryogenic Detector Calibration by Inelastic Scattering of Neutrons [PDF]
A method for calibration of cryogenic liquid argon detector response to recoils with certain energy -8.2 keV - is proposed. The method utilizes a process of inelastic scattering of monoenergetic neutrons produced by fusion DD neutron generator. Features of kinematics of inelastic scattering cause sufficient (forty times) increase in count rate of ...

Leveraging the numerous advantages of ammonium‐ion (NH₄⁺)—including cost‐effectiveness, low corrosiveness, preferential orientation, and rapid diffusion kinetics—aqueous NH₄⁺ batteries (AAIBs) have gained significant attention. This review highlights and evaluates the progress of AAIBs utilizing organic electrode materials such as small molecules ...

Moisture‐Dependent Vibrational Dynamics and Phonon Transport in Nanocellulose Materials
Uptake of water in cellulose play an important role in modulating the structure and phonon transport. This study reports how moisture‐dependent structural modification relates to the vibrational dynamics and phonon transport and scattering of nanocellulose using inelastic neutron scattering and wide angle X‐ray scattering.

Mechanical Resonant Sensing of Spin Texture Dynamics in a 2D Antiferromagnet
Detection of antiferromagnetic spin texture in a 2D magnetic crystal is achieved through nanomechanical resonators at radio frequencies. Sharp magnetic transitions that lead to abrupt changes in mechanical linear and nonlinear responses are assigned to antiferromagnetic domain motions.

A novel and efficient method is explored to synthesize 1D single‐crystal sub‐stoichiometric WnO3n‐2 (n = 25) nanowire bundles. The approach utilizes selective low‐energy He+ ion irradiation (27 eV) on Mo‐Ni doped WOx surface, achieving efficient catalyst‐free self‐organized growth of high aspect ratio nanowires at the temperature of 700 °C.
