Wound dressings that promote quick hemostasis and are highly efficient in healing wounds urgently needed to meet the increase clinical demands worldwide. Herein, a dihydrazide-modified waterborne biodegradable polyurethane emulsion (PU-ADH) oxidized hyaluronic acid (OHA) were autonomously cross-linked form hybrid acid-polyurethane (HA-PU) cryogel by hydrazone bonding at -20 °C. Through its specific macroporous structure (which is approximately 220 μm) constructed aggregated PU-ADH particles...
A catalytic asymmetric conjugate allylation was successfully developed to synthesize potential pharmacologically active 4-allyl-2-oxochroman skeletons. dual activation strategy employed by using N,N'-dioxide-Yb(OTf)(3) activate coumarins and (CuOTf)(2)•C(7)H(8) tetraallyltin via transmetalation, respectively. Good yields enantioselectivities were obtained under mild conditions.
Abstract The asymmetric synthesis of 2‐amino‐5‐oxo‐5,6,7,8‐tetrahydro‐4 H ‐chromene derivatives was achieved through a tandem Michael addition–cyclization reaction easily available cyclohexane‐1,3‐dione and ethyl 2‐cyano‐3‐phenylacrylates. Moderate to good yields (up 81 %) high enantioselectivities 89 % ee ) were obtained with chiral salen–cobalt(II) complex. This process air tolerant performed, which provides an efficient method for the 4 derivatives.
Enantioselective Michael addition of malononitrile to chalcones was catalyzed by a simple quinine and Al(OiPr)3 complex products were obtained in good ee as well high yields, which facilitated the asymmetric synthesis biologically active 4H-pyran compound.
Hinckdentine A, a marine-sponge-derived tribrominated indole alkaloid bearing unique indolo[1,2-c]quinazoline skeleton, was completed in 12 steps featuring the construction of Nα-quaternary carbon center by asymmetric azo-ene cyclization. A novel organocatalyst developed to promote high-yielding tribromination, which represents challenging process encountered previous syntheses. Density functional theory calculations scrutinized viable substrates and deciphered origin enhancement C8...
Structured light 3D shape metrology has become a very important technique and one of the hot research topics in face recognition. However, it is still challenging to use digital projector (DLP) scanner achieve high-speed, low-cost, small-size, infrared-illuminated measurements. Instead using DLP, this paper proposes galvanometer project phase-shifted fringes with projection speed infrared up 500 fps. Moreover, measurement accuracy multi-frequency (hierarchical) multi-wavelength (heterodyne)...
The machine learning (ML) as well quantitative structure activity relationship (QSAR) method has been explored for predicting compounds with antibacterial activities at impressive performance. It is desirable to test additional ML methods, select most representative sets of molecular descriptors, and subject the developed prediction models rigorous evaluations. This work evaluated three support vector classification (SVC), k-nearest neighbor (k-NN), C4.5 decision tree, which were trained...
A cooperative chiral guanidine/Ag(I) catalyst system was developed for the asymmetric isocyanoacetate aldol reaction with isatins. The corresponding spirooxindole oxazolines were obtained in good yields (up to 99%), moderate diastereoselectivities 88:12 dr) and enantioselectivities 90% ee).
Abstract Solar‐driven interfacial water evaporation technology is considered as a promising clean production strategy addressing the issues of global pollution and scarcity. In this study, highly efficient polyvinyl alcohol/carbon nanotube/polypyrrole (PVA/CNT/PPy) aerogel evaporator fabricated by combining hydrophilic PVA with superior absorption property carbon‐based fillers coupled photo‐thermal conversion effects. By regulating pore structure aerogel, capillary effect enhanced, thereby...
Security of cyber-physical systems against cyber attacks is an important yet challenging problem. Cyber-physical are prone to information leakage from the physical domain. The analog emissions, such as magnetic and power, can turn into side channel revealing valuable data, even crypto key system. Template attack a popular type side-channel analysis using machine learning technology. Malicious attackers use template profile emission, then recover secret But conventional requires that...
This study aimed to investigate the effect of magnesium (Mg) and strontium (Sr) surface modification on osseointegration titanium (Ti) implants with a hierarchically structured coating. Mg- Sr-doped hierarchical coating has been fabricated Ti implant through hydrothermal method. Scanning electron microscopy (SEM), atomic force (AFM), energy dispersive spectrometer (EDS), inductively coupled plasma/optical emission spectroscopy (ICP-OES) contact-angle measurement have applied characterize The...
The influence of alumina addition on mechanical behavior and fracture properties all-ceramics zirconia dental materials was evaluated. Samples containing 0, 5, 10, 15 wt.% Al 2 O 3 particles were prepared by cold isostatic pressing (200 MPa) sintered at 1500°C for 5 h. Commercial powders investigated bulk density phase formation using Archimedes principle X-ray diffraction (XRD). Bending strength load determined room temperature three-point bending test. In order to study the fracture, we...
A novel strategy for the selective synthesis of ( E )-vinyl sulfone derivatives from p -tosylmethyl isocyanide (TosMIC) and ortho -substituted benzaldehydes has been established.
Abstract The gastrointestinal tract (GIT) microbiome of ruminants significantly influences their nutrition metabolism and health. Current understanding is extensive for bacterial archaeal communities, but limited viral communities within the GIT. To address this, we created Ruminant Gastrointestinal Virome Catalogue (RGVC), which includes 43,981 non-redundant Operational Taxonomic Units (vOTUs), with 89.3% newly identified, derived from 370 samples across 10 GIT regions in seven ruminant...
The clinical demand for occlusal reconstruction increases rapidly with increasing number of patients who have lost their normal occlusion because tooth wear and dentition defects. Occlusal is a special type restoration defined as comprehensive the function stomatognathic system by reestablishing uniform stable relationship between upper lower dentitions. analysis an important part to achieve accurate design adjustment. Digital was conducted monitor movement mandible obtain related data...
