The growing environmental difficulties triggered by enterprises' activities have drawn academics and development experts' attention to mechanisms to advance growth and development without compromising the environment. Discussions about eco-innovation have become topical as a result, yet there still remains a dearth of understanding on the subject. Eco-innovation emphasises the duality of technological innovation and environmental protection as long-term solutions to the inherent tensions between these goals. Despite this, there has been little research on methods to improve eco-innovation performance, taking into account internal and external factors. Cognizant of the external environment's dynamics, this study, based on institutional theory, investigates how institutional pressure affects eco-innovation. We used a cross-sectional survey approach to draw data from 155 businesses. Results revealed institutional pressures, that is, normative, mimetic, and coercive, also environmental complexity (EC) has a positive role in promoting eco-innovation. While environmental dynamics was found to have a positive moderating effect on the relationship between normative pressure and eco-innovation, EC was revealed to have a moderating influence on the relationship between mimetic, normative pressure, and eco-innovation. In light of these seminal findings that have received little research attention, we propose policy, theoretical, and practical implications. [ABSTRACT FROM AUTHOR]

Photocatalytic ozonation of organics under simulated solar irradiation with a g-C3N4nanosheet was investigated. g-C3N4was prepared by calcinations of urea and characterized by TEM, BET, XRD and UV-Vis. Oxalic acid and bisphenol A were used as model substances to evaluate its catalytic ability. The results showed that g-C3N4possess 2D nanosheet structure. The degradation ratio of oxalic acid and bisphenol A with g-C3N4/O3/Solar was 1.50 and 1.92 times as great as the sum ratio when it was individually degraded by g-C3N4/Solar and O3, separately. The results of recycling experiment indicated that g-C3N4catalyst is very stable under experimental conditions. [ABSTRACT FROM PUBLISHER]

Graphitic carbon nitride (g-C 3 N 4 )–reduced graphene oxide (rGO) nanocomposites were synthesized successfully by grinding a mixture of melamine and graphene oxide (GO) with different weight ratios, followed by calcination at 550 °C under flowing nitrogen atmosphere. Photoluminescence (PL) analysis was performed to investigate the efficiency of charge separation in g-C 3 N 4 –rGO composite. The result showed that the intensity of emission peak for g-C 3 N 4 –rGO composite is much lower than pure g-C 3 N 4 . The activity of g-C 3 N 4 –rGO composite in photocatalysis and photocatalytic ozonation process was evaluated by degradation of oxalic acid (OA) under simulated solar light irradiation. The results demonstrated that the degradation rate of OA with g-C 3 N 4 –rGO composite was significantly improved compared with pure g-C 3 N 4 in both process. This enhancement was due to the hetero-junction built between rGO and g-C 3 N 4 . Furthermore, during photocatalytic ozonation process, g-C 3 N 4 –rGO composite could trigger a synergistic effect between photocatalysis and ozonation. This study indicated that the metal-free g-C 3 N 4 –rGO nanocomposite showed high solar-light activity in photocatalytic ozonation process, which makes them promising materials for further applications in wastewater treatment.

Objective: To demonstrate the clinical applicability of three-dimensional CT angiography by evaluating the anatomic features and variation of inferior mesenteric artery(IMA) and left colic artery(LCA) in order to provide reference to vessel ligation strategy in laparoscopic rectal cancer surgery., Methods: Clinical and image data of 123 patients receiving abdominal multislice CT at The Sixth Affiliated Hospital from 2014 to 2015 were retrospectively analyzed. The images were 3D-reconstructed with computer 3D CT angiography and arterial enhancement phase images were chosen for analysis. Linear distances from IMA root to abdominal aortic bifurcation and from LCA at IMA root level to IMA root were measured. Branch types of IMA, coursing pattern of LCA, and association between LCA and inferior mesenteric vein (IMV) site were summarized., Results: Of 123 cases, 80 were males and 43 were females, mean age was (46.8±16.6) years, body weight was (57.7±10.4) kg, and BMI was (21.3±3.6) kg/m 2 . The average distance from IMA root to abdominal aortic bifurcation was (42.5±7.9) mm, and this distance was closely associated with body weight (OR=4.771, 95%CI: 1.398 to 16.283, P=0.013). Longer distance tended to appear in the heavier patients. LCA and sigmoid artery (SA) originating from same single IMA was found in 61(49.6%) cases; LCA and SA forking at same point in 35(28.5%) cases; LCA and SA coursing together and forking afterwards in 24(19.5%) cases, and LCA disappearing in 3(2.4%) cases. In 71(57.7%) patients, LCA ascended medial to the lateral border of left kidney, while in 16(13.0%) patients, LCA arranged below the inferior border of left kidney. When the LCA site was higher and the distance from LCA to IMA root was closer [distance from LCA to IMA root level was (24.2±9.9) mm, (30.0±15.2) mm and (66.6±12.3) mm, F=83.2, P<0.001]. At the level of IMA root, LCA located medial to IMV in 21(17.1%) cases, located just lateral to IMV in 54(43.9%) cases, and located lateral and ascended far away from IMV in 48(39.0%) cases., Conclusion: 3D-CT angiography is non-invasive, efficient and accurate in evaluating coursing features and variation of IMA and its branches, which can provide important reference to the surgeons, promising laparoscopic surgery smooth and safe.
