<p>We have re-evaluated the X40x10 benchmark for halogen bonding using conventional and explicitly correlated coupled cluster methods. For the aromatic dimers at small separation, improved CCSD(T)–MP2 “high-level corrections” (HLCs) cause substantial reductions in the dissociation energy. For the bromine and iodine species, (n-1)d subvalence correlation increases dissociation energies, and turns out to be more important for noncovalent interactions than is generally realized. As in previous studies, we find that the most efficient way to obtain HLCs is to combine (T) from conventional CCSD(T) calculations with explicitly correlated CCSD-F12–MP2-F12 differences.</p>

Malignant Skin

Melanoma is a malignant skin tumor that results in poor disease prognosis due to unsuccessful treatment options. During the early stages of tumor progression, surgery is the primary approach that assures a good outcome. However, in the presence of metastasis, melanoma hasbecome almost immedicable, since the tumors can not be removed and the disease recurs easily in a short period of time. However, in recent years, the combination of nanomedicine and chemotherapeutic drugs has offered promising solutions to the treatment of late-stage melanoma. Extensive studies have demonstrated that nanomaterials and their advanced applications can improve the efficacy of traditional chemotherapeutic drugs in order to overcome the disadvantages, such as drug resistance, low drug delivery rate and reduced targeting to the tumor tissue. In the present review, we summarized the latest progress in imaging diagnosis and treatment of melanoma using functional nanomaterials, including polymers, liposomes, metal nanoparticles, magnetic nanoparticles and carbon-based nanoparticles. These nanoparticles are reported widely in melanoma chemotherapy, gene therapy, immunotherapy, photodynamic therapy, and hyperthermia.

AbstractArtificial nanorobot is a type of robots designed for executing complex tasks at nanoscale. The nanorobot system is typically consisted of four systems, including logic control, driving, sensing and functioning. Considering the subtle structure and complex functionality of nanorobot, the manufacture of nanorobots requires designable, controllable and multi-functional nanomaterials. Here, we propose that nanozyme is a promising candidate for fabricating nanorobots due to its unique properties, including flexible designs, controllable enzyme-like activities, and nano-sized physicochemical characters. Nanozymes may participate in one system or even combine several systems of nanorobots. In this review, we summarize the advances on nanozyme-based systems for fabricating nanorobots, and prospect the future directions of nanozyme for constructing nanorobots. We hope that the unique properties of nanozymes will provide novel ideas for designing and fabricating nanorobotics.
