To summarise research studies on scar laser therapy since the 21st century using bibliometric methods, and to speculate on the possible development in the future. The literature about scar laser therapy in Web of Science database was searched. CiteSpace and VOSviewer were used to analyse main countries, institutions, journals，subject hotspots and trends, etc. A total of 884 papers have been published since the 21st century. These publications were written by 653 authors from 515 institutions in 58 countries. The United States published 287 papers in this field and ranks first. Laser in Surgery and Medicine is the most widely published journal, with Shumaker as the core author. The main keyword clustering includes terms such as combination therapy, wound healing, fractional photothermolysis, experience, scar formation, etc. CiteSpace and VOSviewer were used to sort out and summarise the countries, institutions, authors, journals, research hotspots and frontier topics of related literature about scar laser therapy since the 21st century. The current situation of its application and basic scientific research in clinical treatments were summarised briefly. This provides a new idea for the development and research of scar laser therapy in the future. [ABSTRACT FROM AUTHOR]

In order to promote the actual optoelectronic application of lead-free perovskite CsSnBr3, the stability and optoelectronic properties of metal dopants in the lead-free perovskite CsSnBr3 have been studied systematically by using first-principles calculations based on density functional theory. Cd and Mn doping is more efficient in CsSnBr3 than other considered metal dopants by calculating the doped formation energies. The stability of a doping system is related to the atomic radius of the dopant. Cr, Mn and Cu dopants can enlarge effectively the band gap of CsSnBr3 and show a higher optical absorption coefficient in short wavelength region of visible light compared to undoped ones. Our work may provide a feasible pathway to manipulate and improve the stability and optoelectronic performance of CsSnBr3. [ABSTRACT FROM AUTHOR]

Cutaneous melanoma (CM) is an aggressive cancer; given that initial and specific signs are lacking, diagnosis is often late and the prognosis is poor. RNA modification has been widely studied in tumour progression. Nevertheless, little progress has been made in the signature of N1‐methyladenosine (m1A), 5‐methylcytosine (m5C), N6‐methyladenosine (m6A)‐related regulators and the tumour microenvironment (TME) cell infiltration in CM. Our study identified the characteristics of m1A‐, m5C‐ and m6A‐related regulators based on 468 CM samples from the public database. Using univariate, multivariate and LASSO Cox regression analysis, a risk model of regulators was established and validated by a nomogram on independent prognostic factors. The gene set variation analysis (GSVA) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) clarified the involved functional pathways. A combined single‐sample gene set enrichment analysis (ssGSEA) and CIBERSORT approach revealed TME of regulator‐related prognostic signature. The nine‐gene signature stratified the patients into distinct risk subgroups for personalized prognostic assessment. Additionally, functional enrichment, immune infiltration and immunotherapy response analysis indicated that the high‐risk group was correlated with T‐cell suppression, while the low‐risk group was more sensitive to immunotherapy. The findings presented here contribute to our understanding of the TME molecular heterogeneity in CM. Nine m1A‐, m5C‐ and m6A‐related regulators may also be promising biomarkers for future research.

Passive radiative cooling material of cellulose by coupling inorganic nanoparticles, have demonstrated competitive advantages in sustainably cooling buildings and constructions due to their voluminous availability, biodegradability, renewability, and natural origin. However, the weak stability of cellulose-inorganic nanoparticle materials when exposed to water or external forces remains a significant challenge that impedes their practical application. In this study, we proposed an easy-to-prepare, scalable, and robust cooling cellulose composite by coupling nano-SiO 2 and cellulose acetate (CA) within cellulose fibers, using the mature pulping and paper process (filling of inorganic particles of nano-SiO 2 and subsequent sizing of polymer of CA). More importantly, the CA molecules form the strong bonding with the cellulose molecules due to the high similarity of their molecular structure, which makes CA function as a "glue" to effectively fasten nano-SiO 2 on the cellulose fibers. Correspondingly, our cellulose composite features desirable robustness and structural stability even undergoing mechanical beating and water-soaking treatments, demonstrating its excellent robustness and desirable adaptability to natural environments, such as wind and rain. As a result, despite undergoing water-soaking (for 40 days) or environmental exposure (for 90 days), the cooling cellulose composite still exhibits excellent solar reflectance (>95 %) and infrared thermal emissivity (>0.95 at 8–13 μm), enabling sub-ambient temperature (∼6.5 °C during daytime and ∼8 °C at nighttime) throughout the day. Our cooling cellulose composite demonstrates promising potential as an environmentally friendly, low-cost, and stable cooling material in our low-carbon society. A robust, sustainable, low-cost and scalable cellulose composite is developed via loading nano-SiO 2 and cellulose acetate (CA) into cellulose fiber network, which demonstrates superior water resistance and long-term stability of cooling. In such cooling composite, cellulose fibers function as skeleton structure to give the deposition location of nano-SiO 2 and CA molecules; both nano-SiO 2 and CA strengths the solar reflectance and thermal emissivity of natural cellulose; CA endows the cellulose composite with high water-proof uniqueness (water contact angle >110°), and structural stability via effectively bonding nano-SiO 2 and cellulose, thus showing super-stably cooling capability in outdoor environments. The prepared cooling cellulose composite endures long-term exposure to sun and rain weather (>3 months), and still features stable and superior cooling capability, as well as self-cleaning distinction.
