Standalone Highly Efficient Graphene Oxide as an Emerging Visible Light-Driven Photocatalyst and Recyclable Adsorbent for the Sustainable Removal of Organic Pollutants.

Carbon-based nanostructures are promising eco-friendly multifunctional nanomaterials because of their tunable surface and optoelectronic properties for a variety of energy and environmental applications. The present study focuses on the synthesis of graphene oxide (GO) with particular emphasis on engineering its surface and optical properties for making it an excellent adsorbent as well as a visible light-active photocatalyst. It was achieved by modifying the improved Hummers method through optimizing the synthesis parameters involved in the oxidation process.

Drug Delivery Challenges and Current Progress in Nanocarrier-Based Ocular Therapeutic System.

Drug instillation via a topical route is preferred since it is desirable and convenient due to the noninvasive and easy drug access to different segments of the eye for the treatment of ocular ailments. The low dose, rapid onset of action, low or no toxicity to the local tissues, and constrained systemic outreach are more prevalent in this route. The majority of ophthalmic preparations in the market are available as conventional eye drops, which rendered <5% of a drug instilled in the eye.

Prospective for Diagnosis and Treatment of Diabetic Retinopathy.

Diabetic retinopathy is a posterior eye disorder in which damage occurs to the light sensitive retina due to diabetes mellitus. This disorder specifically affects people aged between 18-64 with type ІІ diabetes. This disease progresses through different pathophysiological pathways, which include oxidative stress, inflammation, stimulation of the growth factor in the eye's vasculature, isoforms of protein kinase C, and also the activation of the hexosamine pathway.

Processable dispersions of photocatalytically active nanosheets derived from titanium diboride: self assembly into hydrogels and paper-like macrostructures.

Titanium diboride (TiB), a layered ceramic material, is well-known for its ultrahigh strength, wear resistance, and chemical inertness. In this work, we present a simple one-pot chemical approach that yields sheet-like nanostructures from TiB. We serendipitously found that TiB crystals can undergo complete dissolution in a mild aqueous solution of HO under ambient conditions.

Organogels composed of trifluoromethyl anthryl cyanostyrenes: enhanced emission and self-assembly.

A series of α-cyanostyrenes bearing anthracene and electron withdrawing trifluoromethyl units were designed and synthesized. The α-cyanostyrene skeleton favors aggregation induced enhanced emission behavior due to the restriction of intramolecular rotations. Remarkably, the anthryl cyanostyrenes bearing simple trifluoromethyl (CF3) substituents form stable organogels with enhanced fluorescence emission compared to their solution state.
