AI Article Synopsis
- A microperiodic structure known as holographic polymer dispersed liquid crystals (LCs) is created using a photo-induced phase separation technique, involving different LC composites.
- The study examines how temperature and polarization affect the diffraction properties of these LC composite gratings.
- The changes in refractive index due to the LCs' transition from a nematic to isotropic state at higher temperatures facilitate holographic image reconstruction.
Article Abstract
A microperiodic structure composed of polymer and liquid crystal (LC) phases, called holographic polymer dispersed LC, is fabricated by a photo-induced phase separation technique using LC composites with different physical properties, such as refractive indices and clearing points. Effects of thermal modulation on diffraction properties of LC composite gratings are experimentally investigated in the viewpoints of polarization and temperature dependences. The diffractions based on the change of refractive index induced by the nematic-isotropic transition of LCs with the increase of temperature are applied for a holographic image reconstruction.

Article Synopsis
- Recent research indicates that blocking the RIPK1/RIPK3/MLKL necrosome can help reduce inflammatory pain linked to conditions like demyelination in the central nervous system.
- This study tests necrostatin-1s (Nec-1s), a specific RIPK1 inhibitor, on LPS-induced inflammatory pain in male mice, assessing pain sensitivity through hot plate tests and examining related protein changes.
- Results show that Nec-1s not only prevents LPS-induced pain relief but also reverses the activation of key proteins and signals involved in inflammation and demyelination, suggesting that RIPK1 inhibitors could be a promising treatment for managing inflammatory pain.
Conserved ancillary residues situated proximally to the VIM-2 active-site affect its metallo β-lactamase activity.

Verona-integron-metallo-β-lactamase (VIM-2) is one of the most widespread class B β-lactamase responsible for β-lactam resistance. Although active-site residues help in metal binding, the residues nearing the active-site possess functional importance. Here, to decipher the role of such residues in the activity and stability of VIM-2, the residues E146, D182, N210, S207, and D213 were selected through in-silico analyses and substituted with alanine using site-directed mutagenesis.

Nickel complexes are a potential candidate for antibacterial and antifungal activity. A new Ni (II) complex, bis(2-methoxy-6-{[(2-methylpropyl)imino]methyl}phenolato)nickel (II) (2), was synthesised by reacting, bis(3-methoxy-salicylaldehyde)nickel (II) (1) with isobutylamine. It was characterised by single crystal X-ray diffraction (ScXRD), UV-Vis, NMR, IR, mass spectrometry, and thermogravimetry (TG) to study its structure and physico-chemical properties.

Triply periodic minimal surface (TPMS) metamaterials show promise for thermal management systems but are challenging to integrate into existing packaging with strict mechanical requirements. Composite TPMS lattices may offer more control over thermal and mechanical properties through material and geometric tuning. Here, we fabricate copper-plated, 3D-printed triply periodic minimal surface primitive lattices and evaluate their suitability for battery thermal management systems.
