Embracing Creative Nonconformists and Promoting Them May Require Leaders' High Control Appraisals

Journal of Organizational Behavior, EarlyView.
ABSTRACT Promoting creative employees is essential to innovation and organizational success. However, leaders do not always embrace the nonconformist nature of creative behaviors. This study examines how leaders' control appraisals—a personal orientation reflecting their belief in their own ability to control situations—influence their receptiveness ...

Mass Spectrometry Structural Proteomics Enabled by Limited Proteolysis and Cross‐Linking

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The exploration of protein structure and function stands at the forefront of life science and represents an ever‐expanding focus in the development of proteomics. As mass spectrometry (MS) offers readout of protein conformational changes at both the protein and peptide levels, MS‐based structural proteomics is making significant strides in the

Thermal Interaction Mechanisms of Ammonium Perchlorate and Ammonia Borane

Molecules
Ammonia borane (AB), with a theoretical hydrogen content of 19.6 wt%, is constrained by its low crystalline density (0.758 g/cm3) and poor thermal stability (decomposing at 100 °C).

Kinetic Compensation of Barrel Launch Under High‐Speed Solid‐Phase Particulate Impacts

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT An accurate launch‐dynamics computational method is critical for barrel weapon service life assessment and multiphase physics field refinement. Given the lack of studies on the solid‐phase buildup behavior at the projectile base, this paper provides an improved method for calculating the launching dynamics under high pressure and high speed ...

Inhibiting aluminum agglomeration and enhancing combustion in composite propellants via perfluoropolyether

Results in Engineering
Aluminum powder is widely incorporated into solid propellants to boost their specific impulse, yet its coalescence into large agglomerates during combustion impairs ballistic performance by reducing combustion efficiency, increasing two-phase flow losses,
