A novel bandage for better healing of wounds

Researchers have developed a dermal patch with a blend of natural healing agents and polymers in a bilayer structure for improved wound healing

Wound dressings have evolved considerably from the herbal concoctions and magical potions that were popularly accepted as therapy, until the 19th century. Today, wound care is no longer just using a piece of gauze dipped in Dettol. With bioactive agents, nanoparticles, antioxidant agents, growth factors, polymers and more, the science of wound healing is advancing continually.

Money rewards are less likely to improve mood if you are in pain.

University students who experience physical pain perform worse on tasks and have lower moods than those without pain.

Everyone experiences some physical pain in life. Pain affects our mood. Research has shown that people diagnosed with long-term pain frequently experience a negative mood. Would it be similar for people whose pain is not severe enough to consult a doctor and get it diagnosed, that is, sub-clinical?

Better face shields, better protection: hydrophobic coating helps mitigate COVID-19 exposure

Researchers improve the efficiency of face shields by coating them with a hydrophobic layer.

Face shields act as primary barriers to airborne disease-carrying droplets. They are effective in closed spaces such as aircraft cabins and offices where chances of exposure to the droplets from speech, breath, cough or sneeze are high. Face shields have assumed importance during the COVID-19 pandemic, and simple face shields made from plexiglass plastic or polyethylene terephthalate (PET) are available for public use.

A ‘spongy’ liquid to clean up industrial carbon dioxide

A porous liquid composite can convert adsorbed carbon dioxide from industrial effluents to calcium carbonate

Globally, carbon dioxide emissions from human and industrial activities are rising alarmingly, and the gas is escaping into the atmosphere. Industries use physical and chemical absorption methods to capture carbon dioxide from industrial emissions. However, these methods can only capture and store carbon dioxide, which must be transported to a permanent storage site, which requires spending energy additionally.

Wearable sweat sensors on a bandage

Researchers develop thread-based sensors to detect changes in metabolite levels in sweat. 

Metabolism — or the processing and utilisation of energy resources to sustain life — results in a number of by-product molecules called metabolites. Medical practitioners measure the concentration of these molecules in body fluids such as blood, urine, sweat and saliva to test whether the body is functioning normally. While biannual check-ups suffice for the regular population, people with chronic diseases need to monitor their medical conditions constantly.
