Magnetic anisotropy slows down magnetic relaxation and plays a prominent role in the design of permanent magnets. Coordination compounds of Co(II) in particular exhibit large magnetic anisotropy in the presence of low-coordination environments and have been used as single-molecule magnet prototypes. However, only a limited sampling of cobalt's vast chemical space has been performed, potentially obscuring alternative chemical routes toward large magnetic anisotropy.

- Researchers have developed biocompatible and bioresorbable scaffolds for neural tissue engineering, aiming to enhance the repair and reconnection of injured spinal cord and nerves.
- The scaffolds are created from conductive and nanotopographically-modulated poly(D,L-lactic acid) (PLA) and poly(lactic-glycolic acid) using a replica molding technique and a conductive polymer coating.
- Testing shows that these PLA-based films can retain their electrical and surface properties in liquid for up to three weeks, supporting the growth of nerve cells, making them a promising option for future implantable devices.
Article Synopsis
- Cellular alignment is crucial for the function of various human tissues, and traditional 3D scaffolds for this purpose often require invasive surgical implantation.
- Researchers developed a novel injectable hydrogel that incorporates magnetic nanoparticles, allowing for precise control of the hydrogel's structure using a low-intensity magnetic field.
- The hydrogel demonstrated mechanical properties similar to soft human tissues and promoted cell growth while being safe and biocompatible, highlighting its potential for non-invasive treatment options in tissue regeneration.
We present a self-consistent field (SCF) approach within the adaptive derivative-assembled problem-tailored ansatz variational quantum eigensolver (ADAPT-VQE) framework for efficient quantum simulations of chemical systems on near-term quantum computers. To this end, our ADAPT-VQE-SCF approach combines the idea of generating an ansatz with a small number of parameters, resulting in shallow-depth quantum circuits with a direct minimization of an energy expression that is correct to second order with respect to changes in the molecular orbital basis. Our numerical analysis, including calculations for the transition-metal complex ferrocene [Fe (CH)], indicates that convergence in the self-consistent orbital optimization loop can be reached without a considerable increase in the number of two-qubit gates in the quantum circuit by comparison to a VQE optimization in the initial molecular orbital basis.

Titanium-based implants are considered the gold standard for rehabilitation of edentulous spaces. However, the insurgence of allergic reactions, cellular sensitization and low integration with dental and gingival tissues lead to poor osseointegration, affecting the implant stability in the bone and favoring infections and inflammatory processes in the peri-implant space.
