The compositions of the pure and irradiated films were investigated using X-ray diffraction, which confirmed the amorphous structures of the pristine and the irradiated Ge10Se70Bi20 thin films. The optical parameters such as optical bandgap

Pulsed plasma polymerisation of Carvone: chemical characterization and enhanced antibacterial properties Surf. Innov. (IF 3.5) Pub Date : 2022-06-15 Asad Masood, Naeem Ahmed, MF Mohd Razip Wee, Muhammad ASM Haniff, Ebrahim Mahmoudi, Anuttam Patra, Kim S Siow
The production of suitable coating with excellent antibacterial performance has now become a viable technique for enhancing the functional qualities of various biomedical materials. Here, pulsed plasma polymerisation was used to produce an antibacterial coating from carvone oil of spearmint plant. The coating films have adjustable chemical and physical properties based on the deposition parameter,

Self-propelled drops on hydrophilic microfinned surfaces Surf. Innov. (IF 3.5) Pub Date : 2022-06-13 Qianbing Zhou, Zhihai Jia, Xuejiao Xiong, Jiao Wang, Xinran Dai
Straight and curved hydrophilic microfinned surfaces are prepared in this work by photolithography and sputtering coating techniques using silicon wafers as substrates. The behavioral characteristics of drops on these surfaces are discussed by using image-processing technology. The experimental results show that when a drop is placed on the straight microfinned surface, the front contact line of the

Interfacial behavior of intravitreally injected drugs in silicone-oil-filled eye models Surf. Innov. (IF 3.5) Pub Date : 2022-06-13 Anfisa Ayalon, Alexander Rubowitz, Pritam Kumar Roy, Shraga Shoval, Irina Legchenkova, Edward Bormashenko
This paper is devoted to the interfacial aspects of the intraocular behavior, migration and distribution of commonly injected ophthalmic drugs in eyes filled with medical-grade 1300 cSt silicone oil used as a retinal tamponade agent. Novel in vitro and ex vivo models were created for studying the physical properties of the retinal surface and interfacial spreading of the ophthalmic drugs over retinas

Fabrication of radiative cooling film with superhydrophobic self-cleaning property Surf. Innov. (IF 3.5) Pub Date : 2022-06-06 Dong-Mei Zhang, Hui-Di Wang, Meng-Chen Huang, Ting-Ting Fan, Fu-Quan Deng, Chao-Hua Xue, Xiao-Jing Guo
Radiative cooling materials can cool terrestrial objects without any energy input but are susceptible to rain wetting and dust contamination, which affects badly their cooling characteristics. Herein, this work fabricated a radiative cooling porous film with superhydrophobic self-cleaning properties using poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and poly(vinylidene fluoride) (PVDF)
